  • Effects of grazing disturbance on plant diversity, community structure and
           direction of succession in an alpine meadow on Tibet Plateau, China

    • Authors: Yujie Niu; Siwei Yang; Guizhen Wang; Li Liu; Limin Hua

      To elucidate the effects of grazing intensity and grazing time on plant diversity and community structure, as well as the successional differentiation in an alpine meadow, a controlled grazing trial, with six grazing intensities on an alpine meadow was conducted in the eastern Qilian Mountain region for four years. Using species accumulation curves, RDA ordination and variance decomposition, we analyzed the changes in proportion of dominant species, richness, abundance, as well as the life forms of plant communities under grazing disturbance. Both the grazing intensity and grazing time had a significant effect on these dominant species, richness, abundance, as well as the life forms in the plant community (P <0.01). More detailed results showed that: (1) The richness and abundance of plant species were highest in the light grazing plot, and these increased as time passed. In the heavy grazing plot, the abundance of plant species decreased as time passed, but the richness of these species did not change significantly. (2) The abundance of Gramineae and Umbelliferae were negatively and significantly correlated with the duration of grazing treatments, whereas Plantaginaceae and Geraniaceae were positively and significantly correlated with the grazing intensity. Over time, the abundance of bunch-type plants decreased and other life forms of plants have increased. With the increase in grazing intensity, the plants' abundance with the rosette type did not change, but other life forms of plants decreased. The results of variance decomposition indicated that grazing disturbance has had greater effects on life forms and plant populations, followed by the changes in the dominant species and their abundance, with lesser effects on the richness of the species. Grazing intensity had a greater effect than the duration of the grazing treatment had. The results of PCA showed that the climax community in both the lowest and the highest grazing intensity plots had changed over time. In the sample plots with light grazing intensity, the plant community changed to an Elymus nutans + Poa crymophila community, but later changed to a Melilotoides ruthenicus + Kobresia humilis community under heavy grazing.

  • Hematological indices and oxidative stress biomarkers response to the
           starvation of Clarias gariepinus

    • Authors: M. Bassam AL-Salahy; Ahmed Th. Ibrahim

      Starvation effects for five weeks on energy reserves, oxidative stress and hematological indices in Nile catfish Clarias gariepinus was studied. The low protein level in starved fish may result from the lowering effect of prolonged starvation on protein synthesis rather than due to its degenerating protein. Moreover, the elevated level of serum amino acids may promote gluconeogenesis in liver. In addition, the lipid depletion in starved fish may be related to the preferential uses of lipids as an energy to starve fish. Also, unchanged glycemic level may introduce a potent evidence for the presence of active gluconeogenesis, depending on both amino and fatty acids precursors. Also, kidney and liver showed disturbances in metabolites associated with oxidative damage such as elevations in total peroxide, carbonyl protein and DNA fragmentation; these may cause dysfunction to these organs after five weeks of starvation. Total peroxide, carbonyl protein and DNA fragmentation were significantly increased in gills, liver and kidney by 29.9, 30.9 and 30.5; 83.6, 84.6 and 53.7; 82.4, 43.3 and 75.7%, respectively. Starvation induced severe anemia and loss of body weight in the fish. However, white muscle did not show any oxidative damage after five weeks of starvation.

      Plant functional traits are the plant physiological characteristics which can response to the changes of the living environment and have a certain impact on the ecosystem structure and function. The objective of our study was to explore characters of present functional diversity indices, the relationships between functional diversity and environmental variables, the relevance of species diversity and functional diversity. In this paper, habitat type, seed dispersal, pollination method, life cycle, life form, leaf form, leaf hair type, flowering period and flowering time were chosen as functional traits, and the research were done in the typical forest communities in the Xiaowutai Mountain National Nature Reserve, Hebei. One hundred and forty-eight quadrats (10m×10m) of forest communities were established along altitude gradients, at the same time, species composition, functional traits, and environmental variables were measured in each quadrat. The results showed that functional diversity indices in forest communities that were calculated by functional distances varied greatly. Functional diversity indices (FAD, MFAD, FDp, FDc, FRic, Rao and FDis) had highly significantly positive correlation with Patrick index and showed a linear increasing trend. All the nine functional diversity indices (FAD, MFAD, FDp, FDc, FRic, Rao, FEve, FDiv, FDis) had significantly correlation with Shannon-Wiener index and Pielou index. Only FDiv showed significantly negative correlation, and the other eight functional diversity indices showed positive correlation. Environmental filtering was important to functional diversity pattern, and functional diversity indices showed correlation with environmental variables. Altitude was a significant factor to functional diversity in forest communities. Except for FDiv, other functional diversity indices displayed a decreasing trend along altitude gradients. Among all the functional diversity indices, only Rao and FDis showed significantly positive correlation with aspect. The functional diversity indices (FAD, MFAD, FDp, FDc, FRic, Rao and FDdis) showed a negative correlation with slope, slope position, litter layer thickness, soil thickness, while, they showed a positive correlation with soil temperature and disturbance. All the nine indices were proved successful in the analysis of functional diversity in forest communities with different effectiveness. They were divided into three categories, functional richness (FAD, MFAD, FDp, FDc, FRic), functional divergence (Rao, FDis), functional evenness (FEve, FDis). Meanwhile, each category was highly inter-correlated and each category was relatively independent with other categories. The study of functional diversity provides a number of ecological indication and monitoring methods for the forest, and it can address a wide range of important ecological questions that links species and ecosystems through mechanisms in biodiversity research.

      Avena sp. is a major weed threat cereal cropping and there is a need to the ecological knowledge to provide principles for facilitates their management tactics. The autoecology of strilis oat (Avena sterilis L.) into four localities natural rangelands and cultivated lands at El-Jabal Al-Akhdar, Libya were investigated. The demography studies in the cultivated sites revealed 274 specimens belonging to 15 species, within 15 genera and 6 families (wheat) and 252 specimens for 21 species that belonging to 17 genera and 6 families (barley) respectively. The description analysis in rangelands were reported approximately 185 specimens belonging to 14 species within 14 genera and 5 families (Wadi El-Mashel) and 185 specimens that belonging to 17 species within 16 genera and 5 families (Wedi El-Mienisry). The variation between the cultivated and rangelands sites have higher species richness, species evenness, diversity indexes, and homogeneity with smooth rank abundance plots. However, barley and Wedi El-Mienisry communities were more diverse than wheat and Wadi El Mashel. The correlation analysis between main filed density (MFD) of A. sterilis and diversity was strong negative. The phytotoxicity of A. sterilis water extracts was higher in wheat than barley under experiment conditions, while subterranean parts pose significant allelopathic effects than other parts that affect plant assemblages, communities and explained the lower yield of wheat and barley crops.

      The free-living amoeboflagellate Naegleria fowleri is the only species infects humans world widely distributed. N. fowleri is the causative agent of very rare but severe brain infection called primary amoebic meningo-encephalitis (PAM), a rapidly fatal disease of the central nervous system mainly in immuno-compromised individuals. N. fowleri infects human through the entry of the nose, and it happens when human swimming or diving in warm freshwater, such as lakes, rivers and swimming pools. The disease is acute, and patients often die within 5–10days and before the infectious agent can be diagnosed. Limited information is available about the existence of pathogenic N. fowleri, in Egypt, so the present of N. fowleri is an important public health. In the present study, we examined hundred water, dust and swap samples collected from 5 swimming pools in Cairo, Egypt. Based on morphological characteristics of trophozoite and cyst, flagellation test 56% of thermo-tolerant Naegleria like amoeba was detected. The incidence of thermo-tolerant free-living amoebae reached 84, 80and 70% from water, cotton swap and dust samples, respectively at cultivation temperature of 45°C. The highest occurrence of thermo-tolerant amoebae were recorded in summer (100 & 87.5%) while the lowest one were recorded in winter (58 & 37.5%) in both water and dust samples, respectively. In swap samples, the highest occurrence of thermo-tolerant free-living amoeba was recorded in both summer and spring (100%), while the lowest one was recorded in winter (40%). N. fowleri was performed on 24 samples from a total of 56 (42.2%) samples which are positive by culture. Nested PCR using Mp2Cl5 gene primers that is unique to N. fowleri was carried out. The N. fowleri specific primer showed band at 166bp against 24 of 56 (42.2%) samples. The majority of positive samples unique to N. fowleri was detected in water samples followed by swap samples and finally dust samples 14 of 24 (58%), 7 of 24 (29%), 3 of 24 (13%), respectively. In conclusion, swimming pools water may be the source of Naegleria invasion. The use of molecular methods to identify free-living amoebae N. fowleri could provide a more rapid means to diagnose infections caused by those amoebae.

      Meta-analysis is an effective and popular tool for studies of systemic literature or research cases review. Compared with medicine, the ecological publications with meta-analysis typically addressed more questions, but with a less datasets. Therefore, in ecology the meta-analysis method should have higher credibility as it does in medicine. For the future of meta-analysis in ecology, the more important work is to implement more empirical studies, such as ‘coordinated distributed experiment’, to get more reliable datasets.

      Conservation of marine fauna is a great concern in the present days for a number of reasons. Implementation of marine protected area is considered to be a common practice for the conservation of marine fauna at a specific area. However, in many cases, the present management system of the marine protected areas fails to protect marine fauna. This paper proposes a marine protected area surveillance system that uses airborne image sensing and digital image processing to monitor the marine protected area against illegal vessels efficiently. The system architecture, including the system structure, execution planning, and algorithm, has been described for the proposed surveillance system. It is apparent from this study that the currently proposed marine protected area surveillance system is better than the previously proposed ones.

      Sediments of the Dohezar River in Tonekabon contain high levels of heavy metals and therefore, they were chemically analyzed to determine concentrations of these elements. In fact, this research intended to evaluate the ecological risks of the heavy metals As, Pb, Cr, Zn, and Cu in the river sediments. Contamination indices such as enrichment factor and contamination factor, potential ecological risk index for each heavy metal (Ei), and potential ecological risk index (RI) were evaluated. Considering the average concentrations of the heavy metals at all of the Stations, the maximum average for the elements was zinc and the minimum was copper. Therefore, the averages of changes in the concentrations of the elements are Zn>Cr>Pb>As>Cu. Considering calculation of the enrichment factors for the heavy metals according to the EF classification table, the maximum number of Stations (43.02%) with respect to contamination with As were in class 4(moderately severe enrichment). With respect to enrichment of Pb, Zn, Cr, and copper, the rest of the stations with 83.72, 77.91, 86.05, and 69.77%, respectively, were in class 2 (minor enrichment). Considering the high concentrations of the studied elements in the sediments of the region compared to the background value, and based on calculations related to contamination factor, arsenic with the average of 11.9 exceeded the most from the standard limit. It was followed by Pb with 2.2, zinc with 2, Cr with 1.8, and Cu with1.6 (copper exceeding the least from the standard limit). With respect to Ei (the potential ecological risk index for each heavy metal), arsenic was the element with the highest environmental risk. Moreover, with respect to RI (potential ecological risk index), most Stations were in the low-grade range (low environmental risk). This research used statistical studies on correlation coefficients and cluster analysis to find the origin of the heavy metals in the sediments of the region. The low correlation between the heavy metals in the soil can indicate they probably did not have the same source. Moreover, these elements have different geochemical behaviors due to their low correlation. Finally, the kriging method was employed to extract interpolation maps of the spatial distribution for each of the heavy metals.

      The study of environmental conditions is one of the most important measures in the field of reforestation. The present study was undertaken to assess the environmental status of the mangrove forest of Alibaug, Maharashtra, India with respect to different sixteen physicochemical parameters of water using Geographical information system (GIS) for rehabilitation, conservation and development of the destructed area of the mangrove forest. The Base map of study area was prepared using topographic map and the remote sensing data of Landsat 7 ETM+ for spatial analysis. The distributions of water pollutants were assigned using a GIS approach of Inverse Distance Weighted (IDW). The results showed that the amounts of EC, COD, hardness, O&G, Cl−, Na+, Ca2+, Mg2+, NO3 − and PO4 3 − are higher than the normal ranges in mangrove forest due to natural processes and human activity, industrial and domestic wastewater disposal, oil spillage and agricultural runoff which all eventually affect the water quality of mangrove forest of Alibaug. To identify the areas within the normal ranges of 16 studied parameter, suitability map of water was prepared through an integration of 16 suitability maps of the studied parameters. The suitability map of water classified the water to six classes of suitability in order of moderate>moderate to high>low to moderate>high>low suitable. The areas with classes of 1 and 2 were suitable for the protective measures. Classes 3 and 4 were suitable for replantation and restoration of native mangrove species as well as local communities' cooperation in the participatory protection measures. The areas of classes 5 and 0 need to be designed an urgent management and mitigation plan to reduce impact of human activities. The result of the study also proves the use of GIS as a powerful tool in addressing assessment and monitoring programs of the water quality in the mangrove ecosystems.

      The Life cycle of maize stem borer, Chilo partellus (Swinhoe) was studied in in vitro conditions. Development of stem borer undergoes following stages like egg, larvae, pupa and moth. The egg incubation period ranged from 3 to 6days, larval stage was observed in five instars. The mean value of I, II, III, IV and V instars showed 3.8±0.16, 5.2±0.02, 6.1±0.06, 7.35±1.5, and 10.12±0.29days, respectively and complete larvae period ranged from 42 to 49days. Pupae stage was observed in 8–9days. The pre-mating and mating period was found at 9.10±1.20 and 5.14±1.08h while egg laying period in 4.1±1.32days respectively. Fecundity rate of stem borer is from 262 to 657 eggs. The life span of adult male (3-7) and female (3-8) days was observed with a mean of 6.30±0.85 and 5.10±0.69days respectively. Life cycle of stem borer gets completed in 47 to 51days. Development of quality insects in required quantities at different developmental stages and their timely supply plays an inevitable role particularly for insect-breeding resistant programs. Hence to meet these challenges we had tried to standardize an artificial diet with cost effective to rear Chilo partellus under in vitro conditions.

      Adsorption processes of 4GL on two different bentonite-based sorbents were compared: i) Sodium-bentonite in the presence of a cationic surfactant CTAMB; ii) organobentonite alone. This latter was prepared by exchanging the inorganic cation of bentonite with a quaternary ammonium cation at 100% of the clay's CEC. Batch adsorption studies were conducted to evaluate the effect of various parameters such as the quaternary ammonium cation (CTAMB) loading, contact time and initial 4GL concentration. From the kinetic study, it is interesting to note that Organobentonite exhibits faster kinetics compared to Na-bentonite/CTAMB system. The comparison between isotherm plots makes clear that the presence of CTAMB in solution changes the 4GL isotherm. Compared to organobentonite, the adsorption capacity is higher when CTAMB was present in solution. In this case, the results of 4GL adsorption by bentonite obey to Langmuir model. While for organobentonite, all models seem to be applicable. The difference between the two methods is confirmed by XRD analysis. The performance shown by Organobentonite and Na-bentonite/CTAMB system was suitable compared to other adsorbents, reflecting a promising future utilization in wastewater treatment.

      China has become one of the countries most seriously affected by invasive alien weeds in the world. Weeds impact agriculture, the environment and human health, and conventional control methods such as herbicides are expensive, damaging to human health and unsustainable. As the impacts and costs of weed control in China increase, there is an urgent need to manage some of the more important weeds through more sustainable methods. Classical biological control of invasive alien weeds is environmentally-friendly and sustainable. Biological control in China began in the 1930s with the introduction of two agents into Hong Kong for the control of Lantana camara. Since then, a further seven biological control agents have been introduced into China to control four weed species. In addition, 11 biological control agents targeting seven weed species have naturally spread into China. Together, these biological control agents are helping to control some of China's worst weeds. However, these efforts are only a small portion of the weeds that could be targeted for weed biological control. This paper reviews the current status of weed biological control efforts against introduced weeds in ten provinces and regions in southern China and provides a platform to identify the most effective and appropriate weed biological control opportunities and programmes to pursue in the future. Introducing additional safe and effective biological control agents into China to help manage some of the worst weeds in the region should reduce the use of herbicides and impacts on human health and the environment, while increasing productivity and food security.

      Western Hubei is the most concentrated area of forest resources in Hubei Province, and the knowledge of the distribution characteristics of ecosystem carbon density is important to understand the regional characteristics of carbon density and its mechanism of formation. Carbon density and factors influencing different layers in the ecosystem were studied by using field data. The average carbon density of ecosystems in western Hubei was 159.05t/hm2; the carbon density of different forest types in descending order was Abies fargesii forests (362.25t/hm2), mixed broadleaf-conifer forests (154.13t/hm2), broad-leaved forests (146.09t/hm2), and coniferous forests (135.76t/hm2), and ecosystem carbon density increased with increasing age. The carbon density of the arborous layer, shrub layer, and soil layer of A. fargesii forests was significant higher than that of the other forests (P <0.05), indicating the carbon storage per unit area of A. fargesii forests, which grow at higher elevations, was the greatest. The carbon density in arborous layers of broad-leaved forests, mixed broadleaf-conifer forests, and coniferous forests was 39.29t/hm2, 48.99t/hm2, and 48.39t/hm2, respectively. Those of the soil layer were 102.96t/hm2, 100.97t/hm2, and 82.37t/hm2, respectively, and there were no significant differences among them. Among the three forest types, carbon density in the litter layer was greater than that of the shrub layer, which indicated the litter layer plays an important role in carbon storage. The carbon density of mixed broadleaf-conifer forests was greatest, excluding A. fargesii forests, in medium (58.71t/hm2) and mature forests (79.66t/hm2). Thus, the carbon sink of mixed broadleaf-conifer forests had more potential than the others at the medium and mature forest stage. The soil layer carbon density in different forests constituted 60.67—70.48% of the entire ecosystem, and was 1.70—2.62 times greater than that of the arborous layer. There are many factors influencing ecosystem carbon density, which result from the interaction of environmental and topographical factors. The main explanatory variables of carbon density of the region were altitude, precipitation, and canopy density. The vegetation and soil layer carbon density increased as altitude increased, and the rate of change for every vertical 100m was 1.3t/hm2 and 1.9t/hm2, respectively (P <0.05). Although the annual average precipitation only affected the carbon density of the vegetation, it increased to 4t/hm2 (P <0.01) when average precipitation was >100mm.

      In the World urbanization is a serious problem especially in developing countries which creates serious environmental problems like climatic and ecological changes in the ecosystem. The present paper aims to explain urbanization that causes loss of agriculture lands, biodiversity, soil erosions and grazing in District Dir. Urbanization decreased species richness such as Salix alba and Populus alba in the last few years in the local area. Soil of local area was divided into three different zones and was tested for soil texture and mineral percentage. Zone I soil showed sandy loamy texture with a pH of 8.3, Nitrogen 0.012%, Phosphorus 5.0% and organic matter was 0.74 (ppm). Zone II soil was loamy sand in texture with pH8.1, Nitrogen 0.011%, Phosphorus 6.2%, and organic matter was 0.24 (ppm) while Zone III soil texture was silty clay loam with a pH of 8.1, Nitrogen 0.032%, Phosphorus 11.3%, and organic matter was 0.60 (ppm). The current work concludes that urbanizations affect natural biodiversity and agriculture lands, and that soil erosion and watering-points trampled by livestock is one of the significant problems in district Dir, and that the main degrading factor is the overexploitation of vegetation for fuel-wood and livestock grazing.

      In order to examine germination characters, seedling parameters, water relative content, tolerance index and enzyme activities of seven Hungarian wheat landraces varieties (Tiszadadai, Riscsei, Komloi, Leweucei, Mateteleki, Mikebudai and Nyiradi) under five concentrations of water stress (0, 6, 12, 18, and 24%) of polyethylene glycol (PEG-6000). A laboratory experiment has been conducted through Factorial Experiment in Randomized Complete Block Design (RCBD) with four repetitions at Research Institute of Nyiregyhaza, Hungary. From the obtained results, Leweucei variety was surpassed other studied verities under study and recorded the highest values of all studied characters followed by Mateteleki, Komloi, Nyiradi, Riscsei, Tiszadadai and Mikebudai. Increasing water stress (PEG-6000) from 0 to 6, 12, 18 and 24% significantly reduced germination characters, seedlings parameters, water relative content (WRC), tolerance index and α and β-amylases activities. Generally, under water stress condition, Leweucei and Mateteleki varieties were recorded the highest values of water relative content (WRC), tolerance index (TI) and α and β-amylases activities as well as able to prompt better drought tolerance and could be suggested as a good resource for breeding programs and cultivation under drought stress conditions compared with other wheat landraces varieties.

      Cane is one of the important forest products after timber, form an integral part of a rural and tribal population of many of the tropical countries of South East Asia, Africa and America. Calamus nambariensis Becc. has been recognized as endemic and threatened cane to the North East region of India. The plant is restricted to only two pockets of Assam with a poor population size. Therefore, conservation of this plant through proper scientific investigation is utmost necessary. The present investigation has as its objectives to study the distribution, estimation of population size, standardization of suitable micropropagation methods for reintroduction and reinforcement in suitable wild habitat as determined by ecological niche modelling (ENM) for the purposes of conservation. For improving the conservation status of the species, potential area and habitat for reintroduction was determined using maximum entropy (MaxEnt) distribution modelling algorithm. The population size in both the site was found to be very poor i.e., mean density, frequency of occurrence and abundance in relation to other associated species was 0.600, 29.26 and 2.307 in Nambor Reserve Forest whereas 0.526, 27.407 and 2.112 respectively in Gibbon Wildlife Sanctuary. Macropropagation of C. nambariensis was standardized here through seed germination which was found to be more efficient in terms of time and cost which revealed 87% germination in treated seeds, followed by 61% only for untreated seeds till 90days. It was also observed that seedlings in the hilly slope of Gibbon Wildlife Sanctuary (reinforcement) showed high survivability than that of the hilly slop of Lahorijan Reserve Forest (reintroduction). Further, survival rate was measured for 24months, which revealed significantly very high on an average of 97.85% in both the locations, while 1200 numbers of C. nambariensis plantlets were transferred to the field. The present study could change the population size of C. nambariensis in its natural habitat, proving effective means for preventing extinction and improving conservation status of the plant.

      There are high numbers of endangered birds in Iran. Birds also are indicators of biodiversity in different landscapes and using birds as indicator give us a complete overview about the ecological status of the landscape. In the present study migratory waterfowls were used to identify biodiversity hotspots in Iran. Iran is an interesting place for ornithologists because it is in fact a crossroads of flyways for migratory waterfowls coming from Europe, southern Asia, and Siberia. We predicted the habitat distributions for 27 bird species of Anseriformes in Iran using an ensemble forecasting framework to identify biodiversity hotspots. Moreover, we measured the percentage of overlap between hotspots and protected areas including Ramsar sites. The results showed that suitable habitats for different bird species greatly varied among different ecosystems and they showed dissimilar responses to environmental variables. However, for most species digital elevation model (DEM) was the most important variable in predicting suitable habitats. Our study also revealed that 36.02% of Iran can be considered as suitable habitats for the species and the highest suitability belongs to areas along Zagros and Alborz mountain ranges. Furthermore, the suitable habitats had 7.10% overlap with protected areas and 75% with Ramsar sites. The low overlap between hotspots and protected areas demonstrated the shortage of biodiversity protection in Iran. Therefore, it is essential to select new protected areas based on biodiversity hotspots, and to develop a network of protected areas within those hotspots in Iran.

      A laboratory bioassay was conducted to determine the allelopathic potentials of aqueous extracts from either roots or leaves of seventeen sweet potato [Ipomoea batatas L. (Lam)] cultivars (SP0, SP1, SP2, SP3, SP4, SP5, SP6, SP7, SP9, SP10, SP11, SP13, SP14, SP15, SP16, SP18, and SP19). Most inhibitory rates on Lactuca sativa calculated for leaf or root extracts from the seventeen sweet potato cultivars exhibited positive values and significantly increased with increasing concentration. Germination was totally inhibited at a concentration of 0.05g·mL−1 for leaf water extracts of SP13, SP15, SP18 and at a concentration of 0.05g·mL−1 for both leaf and root water extracts of SP19. Inhibition of root length was clearly greater than inhibition of shoot length for both leaf and root water extracts. Biomass inhibition increased with increasing concentration, but some cultivars showed stimulatory effects at low concentrations, and inhibition was generally more pronounced for root water extracts than for leaf water extracts. Moreover, most synthetical inhibitory rates for both leaf and root water extracts from the seventeen cultivars exhibited positive values and significantly increased with increasing concentration. Comparing the synthetical inhibitory rates for both leaf and root water extracts among the seventeen cultivars, SP19, SP6, SP11, and SP7 had the highest allelopathic inhibition. The inhibitory activity on germination index was the greatest, followed by germination rate, root length, biomass, and shoot length in all bioassays. Inhibition by leaf water extracts was generally greater than inhibition by root water extracts, except in the case of shoot length or biomass. Overall, we conclude that all seventeen sweet potato cultivars have strong inhibitory effects on L. sativa, but that these effects vary with cultivar and plant part, with SP19, SP6, SP11, and SP7 exhibiting the highest rates of allelopathic inhibition.

      The present study investigates the variation in the relative growth, biomass and nutrient allocation in two threatened tree species viz. Magnolia punduana Hook.f. & Th. and Elaeocarpus prunifolius Wall. ex Müll. Berol. grown under three different levels of irradiance. The irradiance ranged between 1 and 12molm−2 d−1. Results showed that the highest relative growth rate (RGR) was achieved under the intermediate light treatment for both the species (mean: 0.005mgmg−1 d−1). The growth response coefficient (GRC) model revealed that net assimilation rate (NAR) was the factor driving the RGR in both species. A significant positive correlation was found between NAR and RGR (R2 =0.33, p =0.000) whereas specific leaf area (SLA) and leaf mass fraction (LMF) was negatively correlated to RGR. Overall, multiple regression of the studied species based on the independent variables viz. NAR, SLA, and LMF showed a significant relation with RGR (F(3,50,53=13.001, p =0.000, R2 =0.43). The biomass distribution in the studied species is in agreement with the “balanced-growth hypothesis” where high irradiance increased allocation to below ground biomass fraction and decreased irradiance increased allocation to the above ground fraction. The highest nitrogen concentration in leaves was observed under the intermediate light treatment. Overall seedlings growth under intermediate light had a higher mean RGR indicating the species' preference for partial light conditions. Long-term experiments under varied light conditions as in the present study would provide useful insight into plant growth strategies in varied environmental conditions.

      The vine total biomass of different planting ages from plants in vineyard (1–12 years) was investigated by analysing biomass in stands with various ages and also simulated using the denitrification-decomposition (DNDC) model in the east Helan Mountains, Ningxia in 2011. The results indicated that the DNDC model accurately simulated the total biomass at different planting ages in the studied vineyard; the simulated results were approximately 93.6% of the measured results, and the biomass determination coefficient R 2 between the model simulation and the in situ observations was 0.948 (p < 0.01), representing a significant correlation. Under the simulation, the vine biomass accumulation was found to be sensitive to the changes of fertilisation depth, soil organic carbon content, pH and other factors, and would effectively increase by appropriate increase of the fertilisation amount and decrease of the irrigation amount at the same time. Therefore, the DNDC model is applicable for simulating biomass in Ningxia vineyards and it has the potential to be widely applied to assess crop biomass variations under different climate conditions or management methods.

      A field experiment was conducted to assess the influences of soil chemical, physical, and biological properties of Alhagi sparsifolia community in Linze, Gaotai, and Guazhou County, Gansu province, China. Results showed that soils sampled were generally infertile with low levels of organic matter, available nitrogen, phosphorus, copper, manganese, and zinc with bacteria dominant microbial communities supporting A. sparsifolia. Available potassium and iron were sufficient in the study sites. With increasing soil layer depth, the contents of organic matter, available nitrogen, phosphorus, potassium, manganese, urease, dehydrogenase, bacteria, and actinomyces in the soil decreased significantly (P <0.05), whereas the concentrations of moisture, available iron, and zinc in the soil increased significantly (P <0.05). The contents of organic matter, available nitrogen, phosphorus, potassium, iron, manganese, zinc, copper, urease, dehydrogenase, bacteria, and actinomyces showed strong seasonal variations (P <0.05). All these variables except dehydrogenase, bacteria, and actinomyces were the highest in summer and the lowest in spring. The comprehensive score of soil qualities was the greatest in Linze, medium in Guazhou, and lowest in Gaotai.

      To expand investigations and insights into the phylogenetic diversity of bacteria inhibiting seafloor biosphere, six Arctic Ocean sediments neighboring the Bering Strait were sampled and their bacterial diversities were investigated by pyrosequencing of 16S rRNA genes. A total of 157,454 trimed sequences were obtained, resulting in 9413 OTUs at the 97% sequence identity (OTU3%). This pyrosequencing allowed detection of higher than 85% of richness estimator Chao1 and Ace at the OTU3% level. Higher coverage (≥0.97) and much less of rare types (singletons, only accounting for 24.5% of all OTU3%) indicated that this pyrosequencing recovered most of bacteria inhabiting these biospheres. At the phylum level, the high relative sequence abundance (42.0% to 63.3%) showed that Proteobacteria was the dominant member at all these sampling sites. At the class level, Deltaproteobacteria, Gammaproteobacteria, and Flavobacteriia composed the majority of bacterial communities, and the relative abundance of Cyanobacteria and Bacilli varied significantly among the six samples. At the genus level, abundant OTUs related with sulfate reduction, including Desulfobulbus and Desulforhopalus, were identified. Shared and unique OTUs analysis revealed that, at the OTU3% level, 508 OTUs were shared by all the six samples, and the number of unique OTUs ranged from 98 (R02) to 195 (NB04). Principal coordinates analysis PCoA analysis revealed that samples C04 and NB04 had the similar communities and were distinct from the others. Canonical correspondence analysis (CCA) revealed that temperature was the most significant factors that correlated with the bacterial community composition. The differences in bacterial compositions and diversities indicate that the similar sediment habitats contain a large variation in microbial biodiversity.

      Crabs belong to the superfamily Ocypodoidea are a significant component of benthic fauna and considered as ecosystem engineers because of their dynamic role as an active burrower in mangrove and estuarine environment. The current investigation was to evaluate the crab burrow density, diameter and total area of burrow opening along the coast of Pakistan. The variations in burrow properties and their relation to sediment characteristics were also evaluated to recognize the most influencing variables of sediments that effects on crab burrows. All crab burrow and sediment characteristics differed significantly (p <0.05) among the monitoring sites. Regression analysis showed that crab density was significantly correlated with burrow density (P <0.001). Moreover, burrow density was noticed significantly greater (p <0.05) than crab density. Pearson correlation analysis reveals that moisture, porosity, organics, sand and mean grain size observed as most influencing the features of sediment to determine the ecological functioning of crab burrows in mangrove and mudflats of Pakistan.

      We studied the interaction effects of 8-different land uses systems viz., forestry (T1), silvopastoral (T2), horticulture (T3), agrihorticulture (T4), agrisilviculture (T5), agrihortisilviculture (T6)>grassland (T7) and agriculture (T8) in 2-altitudinal gradient for three consecutive soil layers of up to 1m deep from sub-montane to low hill sub-tropical zone of Western Himalayas in Himachal Pradesh State of India. All the land uses under agroforestry practices viz., agrisilviculture, silvopastoral, agrihorticulture and agrihortisilviculture showed significantly enhanced values of pH, organic carbon (OC %), available N, P, K and exchangeable Ca, Mg and available S than agriculture land use. A maximum value of soil carbon (1.08%) was observed in forest land use followed by silvopastoral, horticulture, agrihorticulture, agrisilviculture, agrihortisilviculture, grassland and agriculture, respectively. Overall highest values of available N, P and K were observed under forest land use and silvopastoral among agroforestry systems. Available N, P, and K declined with increasing altitude. Exchangeable Mg followed the trend T7 >T2 >T5 >T1 >T6 >T3 >T4 >T8 and available Sulphur as T7 >T3 >T2 >T6 >T5 >T4 >T8 >T1, respectively. The value of exchangeable Ca and available S increased with increasing altitude. From the study it can be concluded that tree based land use systems of subtropical zone of the Himalayan region are more sustainable and environment friendly than agriculture and grassland use systems. Hence, they need to be conserved and promoted on large scale. The outcome of this paper will be helpful in convincing the farmers for adoptions of agroforestry practices in large scale.

      Current research includes the effects of asphalt forest roads on changes of plant cover and tree regeneration from asphalt forest roads edges towards its inner parts in two compartments of Nave Asalem forests located in the north of Iran. For this reason, in each side of road, 6 sample plots (20m×20m) were established for measuring plant species diversity. In each sample plot, ground vegetation and tree regeneration were assessed within nine 2×2m micro plots. In total, 12 sample plots and 108μ plots were established. Results indicated that the road positions were effective on plant species diversity. The highest diversity and evenness indices value were observed down of the road compared to the up of the road position for herbal and tree regeneration layers. The same results were found also for herbal richness indices. Up of road position had the greatest value of richness indices in comparison to the other road position for tree regeneration layer. Also, the results showed that diversity, richness, and evenness indices were decreased with the increasing of distance from the road side for herbs and tree regeneration layers. This study indicated that roads can increase plant biodiversity; that is, tree regeneration density.

      In addition to their ornamental value, butterflies provide value to flowering plants through pollination, which can improve their heterosis. Studying the relationship between butterflies and flowers is useful for understanding the adaptive relationship between them. By observing the pollinating and feeding behaviour of Aporia bieti in the Xiama forest, Gansu, we explored the adaptive relationship between A. bieti proboscis size and the corolla tube length of the flowers. To eliminate interference from the butterfly's sense of smell, we used foam flowers instead of real flowers. The results indicated that (1) of the red, yellow, pink, purple, and white flowers tested, yellow flowers were preferred; (2) there was no distinct difference in the preferences of A. bieti for large- (45mm) and small- (25mm) sized flowers; and (3) A. bieti proboscis length was significantly related to the corolla tube length of the flowers fed on by the butterfly, which suggests co-evolution between butterfly proboscis length and the length of the pollen tube.

      This study was conducted to evaluate the chemical composition of asafoetida (Ferula assa-foetida) essential oil (FAEO) and Shirazi thyme (Zataria multiflora) EO (ZMEO) and their impact on vase life of gerbera cut flowers (Gerbera jamesonii cv. Rosalyn). Five concentrations of both, ZMEO and FAEO including 0, 100, 200, 300 and 400mgL− 1 used as continuous vase solution for gerbera cut flowers. EOs used in this study were extracted by hydrodistillation method using Clevenger apparatus. They were analyzed by GC and GC–MS for determination of the active compounds. Thirty five compounds were identified in ZMEO, mainly including thymol (40.1%), p-cymene (15.5%) and carvacrol (6.5%). Also, thirty compounds were identified in FAEO. The main components were trans propenyl sec-butyl disulfide (21.7%), eudesmol (10-epu-γ) (19.2%) and cis propenyl sec-butyl disulfide (10.2%). The results showed that both ZMEO and FAEO at all concentrations could act as an effective antibacterial compounds and this property increased by increasing their concentration. The results of this research showed that ZMEO increased the vase life at all concentrations but high concentrations of FAEO increased mortality percentage and reduced the vase life of cut flowers. The relative fresh weight and vase solution uptake of gerbera cut flowers increased by the applied EOs treatments. ZMEO at 400mgL−1 and FAEO at 300 and 400mgL−1 resulted the least stem color change. Overall, 200mgL−1 ZMEO and 100mgL−1 FAEO were the best treatments for maintenance of gerbera cut flowers quality during vase life.

      South east of Morocco is one of the biggest cutaneous leishmaniasis disease foci. Despite its non-lethality, this disease causes several socioeconomic and psychological impacts. This disease has lots of risk factors. Some of these are related to the environmental change, and others are linked to the demographic and socio-economical system. The interactions between these risk factors create the need for a multidisciplinary approach to estimate the vulnerability risk to the cutaneous leishmaniasis. In this context, a new index was proposed and six provinces were selected, which are Zagora, Ouarzazate, Tinghir, Errachidia, Figuig, and Tata. The findings depict that in term of anthropogenic vulnerability, Tinghir is the most vulnerable to leishmaniasis followed by Errachidia and Ouarzazate. Geographically, Errachidia has the very high vulnerability score and Figuig have the high vulnerability. The results show also an important risk to leishmaniasis in all provinces regarding the socio-economical component, except for Tata. Regarding services category, Zagora is the most vulnerable. However, for the hygiene, Figuig, Ouarzazate, and Errachidia present the high scores of vulnerability, then the rest provinces. The total score of cutaneous leishmaniasis vulnerability of the selected provinces indicates that Tinghir is the most vulnerable regarding this disease followed respectively by Errachidia, Ouarzazate, Zagora, Figuig, and Tata.

      The presence of Bacillus in natural biofilms which develop in sink drainage pipes is not widely studied. Therefore, the main aim of this study was to isolate and identify Bacillus spp. using the BIOLOG GEN III system as a phenotypic fingerprint and polymerase chain reaction (PCR). A total of 61 biofilms samples were collected from sink drainage pipes in a kitchen and bathroom of different households in Helwan area and both laboratory and hospital collected from National Research Centre (NRC). Bacillus was isolated from the biofilms using HiCrome Bacillus Agar followed by isolates identification by both BIOLOG to the species level and PCR using genus specific primers to the genera level. Bacillus was detected in all tested biofilm samples (61 samples). The highest counts were observed in hospital sink drainage pipes (105 CFU/10 cm2) while; the lowest counts were observed in both bathroom and laboratory sink drainage pipes (102 CFU/10 cm−2). In total, 61% Bacillus isolates were identified by BIOLOG while, 67% isolates were confirmed by PCR. The diversity of Bacillus among species level using BIOLOG were 34% B. cereus, 23% B. subtilis ss subtilis, 17% B. thuringiensis, 16% B. licheniformis and 13% B. amyloliquefaciens. It can be concluded that; PCR is more sensitive than BIOLOG for identification of Bacillus. However, BIOLOG can identify Bacillus at species level and test 94 carbon and chemical sources on a microplate in one shot. Thus, the combination between phenotyping by BIOLOG and molecular approaches such as PCR for identification of bacterial isolates is recommended.

      Feverfew (Tanacetum parthenium) (TP) is a valuable medicinal plant from Asteraceae family with various pharmaceutical and therapeutic properties. A pot experiment was conducted to evaluate the effect of salicylic acid (SA) on the physiological and morphological responses of TP under salinity stress. Salinity was induced by NaCl and CaCl2 (2:1) at 30, 60, 90, 120, 150 and 180mM levels. SA was applied as foliar application at 0, 200 and 300ppm concentrations. Plant height, leaf and shoot number, fresh and dry weight and essential oil, starch, sugar, protein, proline, catalase (CAT), peroxidase (POD), and ascorbic peroxidase (APX) contents were as measured morpho-physiological traits. The results showed that SA significantly (P ≤0.05) improved the measured traits and caused higher tolerance in TP plants under salinity stress. The essential oil content increased with increasing the salinity level up to 90mM, which was more significant when combined with SA application. All of the measured traits except proline content, antioxidant enzymes, essential oil and sugar decreased at high salinity levels.

      The aim of this study is to investigate the antifungal activity of mycelia of Pleurotus ostreatus (white oyster mushroom) and licorice (Glycyrrhiza glabra) root extract against three undesirable fungi. They are Trichoderma spp., Trichoderma harzianum I and Trichoderma harzianum II which was tested on PSA (potato sucrose agar) medium enriched with licorice (Glycyrrhiza glabra) root extract (PSA-G media) using three concentrations (0.05, 0.10 and 0.20g/L) in alone and dual cultures. Trichoderma spp. showed less mycelial growth of 8.75, 9.17 and 9.50mm/day on PSA-G0.05, PSA-G0.1 and PSA-G0.2 respectively compared with 10.25mm/day on fresh PSA (control) in dual culture. The best mycelial growth inhibition was recorded on PSA-G0.2 (14.97%) by T. harzianum II in alone culture opposite 63.72% in dual ones. The lower mycelial growth rate of T. harzianum I was 17.75mm/day on PSA-G0.1 (0.10g/L). In dual culture, overgrowth time of T. harzianum I had 5days compared as approx. 6days in alone culture. Generally, when the concentration of licorice extract increased, the mycelial growth rate of the undesirable fungi decreased. Also, all PSA-G media, especially PSA-G0.2, indicated low growth averages compared with the control (fresh PSA) against the pathogen while this concentration encourages growth of oyster mushroom. Also, this concentration reduced the density of sporulation of green molds; therefore, this concentration can be applied to reduce influence this pathogen in cultivation farm.

      Present research work investigated the impact of hexane extract of Lantana camara leaves on the survival, survival duration, growth and development of the Dysdercus koenigii. Newly emerged fifth instar nymphs were exposed to nine concentrations viz. 10%, 5%, 2.5%, 1.25% 0.1%, 0.05%, 0.025%, 0.0125% and 0.00625% of the extract by ‘dry film residual method’ for 24h. The results indicated that the survival and the growth of the nymphs decreased with increasing concentrations of the L. camara extract. The nymphs presented developmental malformation including incomplete moulting followed by death of the moulting nymphs, supernumerary nymphal instars, adults with wing deformities, and adults with exuviae attached to the body. The GC–MS analysis of the extract indicated presence of phytoconstituents with insecticidal activities, and intermediates of the juvenile hormone biosynthetic pathway. It was surmised that these intermediates individually or synergistically influence JH biosynthesis. L. camara extract causes mortality, inhibits growth and development and results in developmental anomalies in the D. koenigii thus indicated its potentials in the ‘integrated pest management’.

      This study provides an introduction and a novel view of the impacts of oil refineries industry on human health, ecosystem quality and resources. The scope and issues for dealing with these challenges are rather wide and complex because the Oil refineries are complex facilities. Several processes, such as distillation, vacuum distillation, or steam reforming are required to produce a large variety of oil products such as gasoline, light fuel oil or bitumen. The goals, perspectives and expectation for the environmental practice and control have changed dramatically over the last couple of decades. Hence the required approach has to be multidisciplinary, based on established scientific concepts and sound engineering principles. The environmental impacts of oil refineries are assessed using the technique of life cycle assessment (LCA). In this paper, only the material production phase of the bitumen LCA is considered. To improve the quality of the LCA, a regionalized life cycle inventory (LCI) database for the Oil refineries and commercial LCI databases are used to validate and model unit processes with an LCA software.

      The effect of root surface iron plaque formation on the uptake, transfer and accumulation of La and Nd in the rice root system was evaluated by using solution cultures. The results showed that La and Nd pollution stress inhibit formation of rice root surface iron plaques. The amount of La and Nd absorbed by the rice root surface iron plaque rose with the increase of La and Nd solution concentrations. Iron plaque formation on the rice root surface significantly decreases the La and Nd concentrations in rice roots and shoots. At growth solution La concentrations of 0.1, 0.5, and 1.0mmol.L−1, concentrations of La in rice roots with induced iron plaques decreased by 17.1%, 37.4%, and 31.2%, respectively, and concentrations of La in rice shoots decreased by 43.9%, 60.6%, and 27.0%, respectively, when compared to plants with non-induced iron plaques. Also, with Nd solution concentrations of 0.1, 0.5, and 1.0mmol.L−1, the Nd concentrations in rice roots and shoots of plants with induced iron plaques decreased by 21.0–31.7% and 22.7–47.5%, respectively when compared to plants with non-induced iron plaques. Iron plaque formation on the rice root surface affects the accumulation and transfer of La and Nd in rice roots. Accumulation of La and Nd was greater in rice roots than in rice shoots regardless of whether the plants had induced or non-induced iron plaques. Transfer coefficients of iron plague on rice root surface and root system under La treatments were both higher than those under Nd treatment. For rice roots and iron plaques on the root surface, the enrichment coefficient in the La treatment group was less than that in the Nd treatment group, while for rice shoots, the enrichment coefficient in the La treatment group was greater than that in the Nd treatment group. Clearly, the mechanisms governing the effect of iron plaque on La and Nd uptake and transfer in the rice root system are rather complicated.

      Soil enzyme activity and microorganism community can be changed through different long-term fertilization patterns. However, the effect of different fertilization practices on soil microorganisms might differ among crop systems. The objective of the study was to reveal the change of soil enzyme activity and soil microorganism community in different fertilizations both in upland and paddy soils. Therefore, based on long-term fertilization experiments in upland soil started in 1986 and adjacent paddy soil experiment commenced in 1981, with both consisting of 4 treatments: Control (no fertilization), N (only nitrogen fertilizer), NPK (nitrogen, phosphate and potassium fertilizers) and NPKM (nitrogen, phosphate and potassium fertilizers plus organic manure), grain yield, soil fertility, activities of soil urease, catalase, acid phosphatase, microorganism community (the number of bacteria, fungus and actinomycete) were analyzed. The result showed that: the highest grain yield was attained under the application of chemical fertilizers plus manure, as compared with Control, NPKM significantly increased the grain yield by 908.63% in corn and 118.80% in rice (p <0.05). Meanwhile, NPKM treatment increased significantly soil organic matter and nutrient contents in upland and paddy soils. Interestingly, there was no significant difference in soil pH among all the treatments of paddy soil, but in upland, NPKM increased pH in comparison to Control by 23.06% (1.15 units of pH). Compared with Control, soil urease, catalase activities, bacteria and actinomycete numbers of NPKM were increased by 321.39%, 129.64%, 229.79%, 85.81% in upland soil, and 25.11%, 251.12%, 292.83%, 196.34% in paddy soil. However, in paddy soil, the soil acid phosphatase activity of Control, NPK and NPKM treatments were higher than upland soil by 34.87%, 44.81%, 52.73% and 30.11%. Then, the soil fungus and actinomycete numbers of paddy soil were lower than upland soil by 20.20% and 88.29%. Therefore, it indicated that long-term application of chemical and organic fertilizers delivered highest productivity in both experiment but the effect of fertilizer practices differed between land uses.

      Heavy metal contaminations in the environment of mining area have become a global problem. The vicinity of an iron ore mine was investigated to estimate the concentrations of As, Pb, Cd, Mn, Ni, Zn, and Cr in the soil and the feasibility of using native plants for phytoremediation. For this, concentrations of elements in soil samples collected and were analyzed by inductivity coupled plasma optical emission spectrometry. The concentrations of heavy metals and arsenic in the roots and aerial parts of Dactylis glomerata L. and Scleranthus orientalis Rössler were analyzed by inductively coupled plasma mass spectrometer too. As concentrations in the samples surpassed the soil toxicity threshold. Cd concentration in soil samples was considerably high next to mine pit. Neither species was identified as a hyperaccumulator, but both species could be considered as excluder plants for As.

      Pollution is one of the most important factors inhibiting growth in the environment; therefore the effects of zinc pollution were studied in Acer velutinum specie. One year old seedlings of Acer velutinum specie were prepared from nursery, the concentrations of zero and one hundred thirty mg per liter of zinc chloride solution were added to the soil of seedlings pots after calculating and after passing a three-month period of seedling growth, the plant organs were removed, then the amount of zinc concentration in the samples was determined and data were analyzed. The results of the analysis showed that the highest amount of accumulation on the stem, root and soil in treatment concentrations is 87.75, 65.68 and 24.78mgperkg and accumulation of zinc in total chlorophyll and sugar in treatment concentrations is 4.61 and 0.6028mgperg, respectively, and accordingly Acer velutinum specie is suitable for refinement of soils contaminated with zinc.

      The paper describes the bio efficacy of a protease inhibitor; isolated from Allium sativum ‘garlic’ (ASPI); against Aedes aegypti mosquito, a well-known transmitter of dengue and Chikungunya. The purification of protease inhibitor from Allium sativum ‘garlic’ (ASPI) was carried out by ammonium sulfate precipitation followed by Fast Protein Liquid Chromatography using akta DEAE-Cellulose column. The protein fraction demonstrating trypsin inhibitory activity was further evaluated for its insecticidal activity using gut protease inhibition assay and larvicidal assay. ASPI is an inhibitor of porcine trypsin (IC50 of 650.726 μg/mL) and has molecular weight of ~15 kDa determined by SDS PAGE similar to other inhibitors of the Kunitz-type family (14–26 kDa). ASPI demonstrated 50% reduced activity of Ae. aegypti midgut proteases and showed a dose-dependent acute toxicity on Ae. aegypti 3rd instars exhibiting LC50 value of ~50.827 μg/mL. After ten days of larval exposure ASPI resulted in a 24-h delay of larval development and ~72% mortality at 61.5 μg/mL. These results suggest that ASPI may serve as potent insecticidal agent and hence opens a new gateway in the field of phyto-remediation.

      In this paper, a study on the surface and deeper waters of the Yercaud Lake, Tamil Nadu, South India, was carried out to understand the geochemistry of the lake waters and also to determine its utility for agricultural purposes. Totally, 50 surface and deep water samples were collected from Yercaud Lake. Major ion and heavy metals were measured. The data obtained were interpreted using the lake water composition. The mean concentration of physicochemical parameters and heavy metals for the surface and deep waters have the following values, pH (7.6), EC (263.4), Ca2+(16.3), Mg2+(7.4), Na+(19.2), K+(1.5), Cl−(18.2), NO3 −(1.5), SO4 2−(1.5), HCO3 – (97.9), Fe (1.3), Mn (0.1), Cr (0.4), Cu (0.005), Pb (0.31), Zn (0.01), Co (0.095) and Ni (0.075). The data generated reflects that the water samples are dominated by recharge process, especially due to the monsoonal rains and natural springs within the lake. The geochemical data reveals that the lake water is suitable for the agricultural purpose and the chemistry of water is mainly influenced by the weathering of bedrock, especially the charnockites bedrock. The sodium adsorption ratio and sodium percentage (%Na) values indicate that the lake water is suitable for irrigation. Dominant heavy metals in the lake waters are mainly because of the lithogenic as well as through minor anthropogenic inputs. Based on our data it is noted that proper management plans are required to monitor the pollution source in the lake, with strict policy measures.

      Using Superabsorbent is one of the solutions to water shortages in arid and semi-arid regions. In order to evaluate the effect of zeolite and geohumus on the growth of Nitraria schoberi L. species, a factorial experiment in a completely randomized design was conducted with nine replications in Kashan city. The treatments consisted of various zeolite levels (0, 10 and 15wt%) and geohumus (0, 100, 150, 250 gr for hole) and irrigation (normal irrigation, low irrigation). This study showed that superabsorbent application has a positive effect on establishment and other indices such as plant height, large and small canopy diameter and collar diameter. The highest survival percentage was observed in superabsorbent application (100%) and the lowest was measured in control treatment of low irrigation (the soil free of modifying substances) (78%). Also, the most growth indices of the plant are related to the treatment of 250g geohumus with low irrigation treatment. Based on the results, it was found that adding superabsorbent on soil causes more establishment and improves vegetative growth traits. Also, considering the economical price of zeolite superabsorbent compared to geohumus as well as its abundance in Iran, it is recommended to use in order to increase irrigation intervals and reduce costs in desertification projects.

      Both Schisandra sphenanthera (S. sphenanthera) and Schisandra chinensis (S. chinensis) are used as traditional Chinese medicines, but they have different medicinal properties. Because S. sphenanthera is cheaper, it is often used as a counterfeit product for S. chinensis. In the present study, an electronic tongue (e-tongue) was used for discrimination of the two Schisandraceae species. In addition, the contents of schisandrin, schizandrol B, schisantherin A, deoxyschizandrin, and schisandrin B were determined simultaneously by ultra-performance liquid chromatography. Principal component analysis (PCA) and discriminant factor analysis (DFA) were used to establish the mathematical models for species identification, and the classification rates for both methods reached 100%. The e-tongue coupled with multivariate analysis exhibited the excellent performance and classification accuracy, and this was validated by the ultra-performance liquid chromatography results. This simple e-tongue technique could be useful for rapid and accurate identification of S. sphenanthera and S. chinensis.

      To elucidate the effects of grazing intensity and grazing time on plant diversity and community structure, as well as the successional differentiation in an alpine meadow, a controlled grazing trial, with six grazing intensities on an alpine meadow was conducted in the eastern Qilian Mountain region for four years. Using species accumulation curves, RDA ordination and variance decomposition, we analyzed the changes in proportion of dominant species, richness, abundance, as well as the life forms of plant communities under grazing disturbance. Both the grazing intensity and grazing time had a significant effect on these dominant species, richness, abundance, as well as the life forms in the plant community (P <0.01). More detailed results showed that: (1) The richness and abundance of plant species were highest in the light grazing plot, and these increased as time passed. In the heavy grazing plot, the abundance of plant species decreased as time passed, but the richness of these species did not change significantly. (2) The abundance of Gramineae and Umbelliferae were negatively and significantly correlated with the duration of grazing treatments, whereas Plantaginaceae and Geraniaceae were positively and significantly correlated with the grazing intensity. Over time, the abundance of bunch-type plants decreased and other life forms of plants have increased. With the increase in grazing intensity, the plants' abundance with the rosette type did not change, but other life forms of plants decreased. The results of variance decomposition indicated that grazing disturbance has had greater effects on life forms and plant populations, followed by the changes in the dominant species and their abundance, with lesser effects on the richness of the species. Grazing intensity had a greater effect than the duration of the grazing treatment had. The results of PCA showed that the climax community in both the lowest and the highest grazing intensity plots had changed over time. In the sample plots with light grazing intensity, the plant community changed to an Elymus nutans+Poa crymophila community, but later changed to a Melilotoides ruthenicus + Kobresia humilis community under heavy grazing.
