  • Assessment of the Population Status of O. Fedtsch. In the Mountains of
           Uzbekistan

    • Abstract: Currently, the genetic resources of plants are on the verge of gradual disappearance, called genetic erosion. The erosion of genetic diversity implies the loss of diverse genes in individual plant species. Therefore, special attention should be paid to the collection and conservation of genetic resources of endangered plants for future use. The aim of this study is to research the natural coenopopulation of the ancestral species of cultivated plant, Allium oschaninii in the mountains of Uzbekistan. Field studies were conducted in nine coenopopulations in the Turkestan, Gissar, and Alai ranges. For each coenopopulation, a phytocoenotic characteristic given on the sites of 100 m2. When determining the structure of A. oschaninii and the characteristics of the coenopopulation, transects from 10 to 30 sites of 1 m2 were established. The condition of the coenopopulation was assessed by the age structure of A. oschaninii and using a demographic indicator. We found that the condition of the coenopopulation is normal, but incomplete. The condition of the coenopopulations 1, 8, 9 is under threat due to anthropogenic load (overgrazing) and unfavorable factors of the ecotype. The ontogenetic spectrum is centered with a peak on average generative individuals and does not coincide with the characteristic one. Coenopopulations with a left-sided type, with a predominance of juvenile individuals, are formed on stony-gravelly, fine-grained gravel, and soft-soil mountain plains. By biological nature, the ontogenetic spectrum of A. oschaninii is left- sided, with an absolute maximum on one of the pregenerative groups. According to the demographic indicators, in diverse communities and in low-mountain and medium-category habitats and in a static substrate with grazing, the coenopopulation is young, mature, and in a transitional state.

  • Water Quality from the Sources of Non-Centralized Water Supply within the
           Rural Settlements of Zhytomyr Region

    • Abstract: The research was conducted within the territories of rural settlements of Zhytomyr region. A total of 72 sources of non-centralized water supply were surveyed. Water quality was assessed by physical and chemical (pH, iron total, total water hardness) and toxicological (nitrites, nitrates, and ammonium) indicators, the content of which was compared with the norms given in the State Sanitary Regulations and Standards 2.2.4-171-10 “Hygienic Requirements for Drinking Water Intended for Human Consumption.” The assessment of drinking water quality was carried out in accordance with DSTU (National Standards of Ukraine) 4808:2007 and with the water quality index (WQI). It was found that the largest deviations from the norm among toxicological indicators were observed for nitrates – 63.9%. In terms of water quality classes according to DSTU 4808:2007, drinking water from sources of non-centralized water supply of villages showed the following distribution: 2.8% of the samples belonged to class 1 (excellent water quality), 72.2% to class 2, and 25% to class 3. According to WQI, 16.7% of the examined sources of non-centralized water supply had excellent water, 63.9% had good water, and 19.4% had poor water. Despite the fact that the water from the investigated sources of non-centralized water supply was of acceptable quality, it is impotable due to the excessive nitrate content. The results obtained show that there is a need for monitoring of drinking water quality from the sources of non-centralized water supply, especially in rural settlements that are not provided with centralized water supply.

  • Effects of Different Cropping and Land Management Practices on the Quality
           of Irrigated Soils of the Upper Awash Basin, Central Rift Valley of
           Ethiopia

    • Abstract: Irrigation is one way of utilizing the land resources to enhance agricultural production. Irrigation crop production is crucial in the present study area due to its arid and semi-arid climatic characteristics. However, little is known about the influence of different cropping and land management practices on soil quality (SQ). This study aimed to determine the effects of different cropping systems and land management practices on variability of SQ indicators in the Central Rift Valley of Ethiopia (CRVE). To this end, 45 disturbed surface (0‒20 cm) and 24 undisturbed (upper 7 cm) soil samples were collected from four adjacent farms: large-scale perennial farms (LSPF), large-scale annual farms (LSAF), smallholder subsistence annual farms (SHAF), and non-cultivated lands (NCL). Soil analyses were made for selected SQ indicators – particle size analysis, bulk density, soil water content, organic matter, pH, total nitrogen, available potassium and phosphorus, exchangeable bases, and cation exchange capacity. One-way analysis of variance (ANOVA) and Pearson correlation coefficient (r) were computed. Key informants’ interview was conducted to substantiate the data obtained from soil laboratory analyses. As the results confirmed, different cropping and land management practices had significant effects on some SQ indicators. Soil organic matter, total nitrogen, available P, and available K declined significantly (P < 0.05) in the soils of LSAF and SHAF. This is attributed to land management-induced problems such as frequent tillage practice of mono-cropping, high level of mechanization, removal of crop residues/above-ground biomass in LSAF, and use of low external inputs and overcultivation without appropriate land management practices in SHAF. However, LSPF practice resulted in the improvement of key SQ indicators, next to NCL. Therefore, LSPF can be an alternative cropping and land management practice to achieve sustainable agricultural production and land management in semi-arid irrigated lands of CRVE and in places with similar environments.

  • The Effect of Population Pseudo-Rejuvenation in Adverse Changes in Living
           Conditions: A Case Study on the Highland Plant Species in the Ukrainian
           Carpathians

    • Abstract: “Rejuvenation of population” is commonly considered as an increase in the proportion of young individuals in the population. In our opinion, the term “rejuvenation” has to be used in case of an increasing percentage of young individuals providing maintenance or increase of the entire population size. In return, an increasing percentage of young individuals while reducing the number of the entire population should be considered as “pseudo-rejuvenation.” A key feature of rejuvenation is the positive dynamics of the population. Instead, pseudo-rejuvenation is an indicator of negative exogenous or endogenous changes and is evidence of population degradation under adverse environment conditions. The article presents the most common examples of the processes of rejuvenation of populations in different plant species under the influence of anthropogenic and natural factors in the plant communities of the Ukrainian Carpathians. The main causes of rejuvenation and pseudo-rejuvenation of populations of the target plant species have been identified. Studies of population structure changes in situ were performed using both long-term monitoring transects laid 5–40 years ago and in new sites. Transects are located in the alpine, subalpine, and upper forest zones of the Ukrainian Carpathians in the height range of 1200–2000 m a.s.l. The study areas cover the most common alpine and chionophilic communities, some forest and subalpine phytocenoses.

  • The Value of Protected Areas Ranger Service Personnel for Biodiversity
           Monitoring: Case Study in Paklenica National Park (Croatia)

    • Abstract: To preserve the long-term survival of habitats and wildlife, it is necessary to monitor their status. In protected areas, that is, biodiversity centres, rangers have excellent knowledge of specific locations and they spend a large amount of time in the field. But since rangers are not required to have a university degree, the question is whether they can be an added value in baseline survey monitoring. To investigate this issue, a case study was conducted in the Paklenica National Park (Paklenica NP), Croatia, using camera trapping survey between 2011 and 2016 at 22 camera sites. The aims of this survey were (1) to collect baseline data of mammalian diversity, (2) to analyse the regulatory effect of top predators on the trophic pyramid through top–down effects and (3) to estimate the data gathered by ranger service from the Paklenica NP. Data gathered through this study represents the first peer-reviewed list of medium- to large-sized mammals for Paklenica NP, as up till now, there is no peer-reviewed published paper of Paklenica NP mammalian diversity. Results showed that the recorded top predator–mesopredator–prey ratios were concordant with the trophic pyramid hypothesis. Also, as it was expected according to the literature, species richness indices were higher when top predators were present. On analysing the costs for conducting camera trapping survey by external and internal services, a significant difference was observed. Internal rangers’ cost was nine times lower than the external service cost. Future research run by rangers needs to be conducted in way to capture all mammalian biodiversity. Therefore, we propose camera trapping methodology for rangers in the protected areas since this may be an invaluable tool for biodiversity monitoring.

  • Influence of Plants on the Spatial Variability of Soil Penetration
           Resistance

    • Abstract: Soil penetration resistance is an informative indicator to monitor soil compaction, which affects a range of ecological processes in floodplain ecosystems. The aim of the investigation was to reveal the influence of vegetation cover on the spatial variability of penetration resistance of floodplain soils. The study was carried out in the elm oak forest in the floodplain of the Dnipro River (Dniprovsko-Orilsky Nature Reserve, Ukraine). The study of the soil profile morphology was performed in accordance with the guidelines of the field description of soils FAO. The soil penetration resistance was measured in the field using the Eijkelkamp manual penetrometer to a depth of 100 cm at 5-cm intervals within the polygon consisted of 105 sampling points. Vegetation descriptions were made in a 3×3-meter surrounding from each sampling point. The soil penetration resistance was found to regularly increase with increasing depth. The changes in resistance values were insignificant until 25–30 cm depth. After that, there was a sharp increase in penetration resistance up to the depth of 70–75 cm, after which the indicators plateaued. In the three-dimensional aspect, the spatial variation of soil penetration resistance can be fractionated into broad-scale, medium-scale, and fine-scale components. Tree vegetation induces a broad-scale component of soil penetration resistance variations, which embraces the whole soil profile. The herbaceous vegetation induces a medium-scale component, which embraces the upper and middle parts of the soil profile. The fine-scale component is influenced by pedogenic factors.

  • Tree Species Biodiversity in Small Ukrainian Towns

    • Abstract: Biodiversity is one of the important indicators of ecosystem sustainability, which is less studied in relation to urban areas, particularly Ukraine, and even more so in small towns. Taking the example of three small Ukrainian towns, the biodiversity of tree species is compared in the article. The studied small towns are located in two geographic zones, mixed forests (Polissya) and forest-steppe, and administratively, in Chernihiv and Kyiv regions. An inventory of trees in the residential area of Ukrainka, in the central streets of Novhorod-Siverskyi, as well as in the central part and all streets of Vyshhorod was conducted. Thus, the species richness of trees both between the studied towns and between its central part and the whole territory of the town was compared. The species structure of tree plantings in terms of richness, diversity, dominance, alignment, and similarity was assessed. The obtained results were subjected to cluster and correlation analysis. It was found that the greatest diversity is characteristic for the dendroflora of the whole territory of Vyshhorod, which is the fastest growing town, located closest to the capital. The dendrofloras of small towns were quite similar to each other. The values of similarity indices varied in a wide range: Jacquard’s index from 0.26 to 0.56 and Sørensen index from 0.41 to 0.66. The lowest degree of similarity was found with the dendroflora of the most distant Novgorod-Siverskyi town. Mainly the urban plantings require enrichment of the tree species composition, taking into account their resistance to anthropogenic impacts and climate change.

  • Assessment of Naturalness: The Response of Social Behavior Types of Plants
           to Anthropogenic Impact

    • Abstract: The aims of this research are to assess the relationship between the concepts of hemeroby and naturalness of plant communities and to test the hypothesis about the ordinal nature of the response of social behavior types of plants under anthropogenic influence. Study area is the recreational zone of the Botanical Garden of Dnipro National University, named after Oles Gonchar, Dnipro City, Ukraine (48.43°N 35.05°E). Four polygons (105 relevés in each) were examined. Two polygons were in the zone after park reconstruction, and two were in the zone without reconstruction. The vegetation community ordination was performed using RLQ analysis. The Q-table was represented by eight dummy variables, which indicated social behavior types. The most important predictors of naturalness were aggressive alien species and invaders and weeds (positive dependence) and disturbance tolerants (negative dependence). The most important predictors of hemeroby were aggressive alien species (negative dependence) and ruderal competitors, invaders, and disturbance tolerants (positive dependence). Naturalness and hemeroby reflect different strategies for transforming a plant community and are not completely symmetrically opposed concepts. The response of a plant community is multivariate, so the naturalness metric based on the social behavior types is only able to distinguish well between the extreme states of a plant community, but is a poor measure for a more detailed assessment of naturalness.

  • Methodology of Wildlife Underpasses Attractiveness Assessment

    • Abstract: The permeability of line barriers in the landscape is often a prerequisite for the survival of the wide spectrum of native species. The aim of this study is to create a methodology for assessing the attractiveness of wildlife underpasses used by animals during migrations, translocations or as a habitat. Understanding the relationship between the parameters of underpasses in the broader landscape-ecological context and their attractiveness for animals is a key aspect in spatial planning and the construction of new linear transport structures, which will significantly help mitigate the barrier effect and isolation of animal populations. The attractiveness assessment is based on the evaluation of the underpass individual parameters and its surroundings through the 8 sub-indexes (openness, substrate, anthropogenic, vegetation, landscape structure elements, ecological networks, potential and real migration/habitat).

  • Water Quality and Zooplankton Assessment of Iyiakwu River, Southeast
           Nigeria

    • Abstract: Water quality and zooplankton assessment of a rural river in Southeast Nigeria was carried out between May 2019 and October 2019 in three stations in relation to anthropogenic activities. The major anthropogenic activity in the river was indiscriminate sand mining. The water samples were collected and analyzed using standard sampling and analytical procedures while zooplankton samples were collected using filtration method. pH and dissolved oxygen values were lower than acceptable limits while some of the biochemical oxygen demand values exceeded the acceptable limit. A total of 447 individuals from 25 zooplankton taxa and three major taxonomic groups were recorded. Copepoda was the dominant group (158 individuals/L), followed by Rotifera (147 individuals/L) and Cladocera (142 individuals/L). Spatially, station 1 had the highest abundance (159 individuals/L), followed by station 3 (152 individuals/L) and station 2 (136 individuals/L). The biodiversity indices (Shannon–Weiner and Margalef) were low while Evenness was high when compared with their respective ranges. This study has shown that the combined effects of season, sand mining and other activities have not adversely affected the water quality and zooplankton community. However, the community structure of the zooplankton groups gave an indication of a moderately polluted environment; attributable to the effects of season and human activities in the watershed. Sand mining is a major activity in the river and needs to be regulated to forestall any adverse effect on the water quality and biota in future as observed elsewhere.

  • Soil Fauna of Ranibari Community Forest, Kathmandu, Nepal

    • Abstract: Ranibari Community Forest (RCF) is the important forest patch present within the highly urbanized Kathmandu Valley with information gaps on soil fauna. This study aimed to explore the soil meso and macrofauna of the forest. Fourteen random quadrats (1 × 1 m2) were laid within seven blocks. Leaf litter samples and soil cores were collected, screened, sieved, and searched under a white sheet, once a fortnight from May to November 2019. The results showed that the diversity, abundance, and richness of soil fauna were the highest in the summer season (H´ = 2.897, abundance = 1,973, S = 84) dominated by Collembola. The Soil Biological Quality Index (QBS-ar) value was also found to be the highest in summer (QBS-ar = 417) and successively decreased in succeeding seasons. Soil fauna was diverse and evenly distributed in soil layers throughout the seasons, but the abundance was greater in leaf litters, particularly in summer. Fauna like Chilopoda, Diplopoda, Haplotaxida, and Isopoda were seen to be affected negatively by soil temperature in summer and autumn seasons. Soil moisture content was found to be positively correlated with immature insects, earthworms, and millipedes in the rainy and autumn seasons. Besides, the pH of the soil was seen to affect Diplura only in the autumn season. The relation of fauna with the physicochemical parameters (temperature, moisture, and pH) and also with other taxa showed their ecological roles and adaptation to a specific microclimate.

  • Temporal Dynamics of Soil Invertebrate Communities in a Vineyard Under
           Treatment with Pesticides

    • Abstract: Phytosanitary treatments with pesticides are widely used to control pests and diseases in vineyards. An important part of the dispersed pesticide reaches the soil, affecting the fauna, producing quantitative and qualitative changes in the edaphic population’s structure and physiological activities. This study aims to evaluate the temporal dynamics of the soil macro and mesofauna through different pesticide treatment periods, where fungicides are the dominant pest control agent. A field experiment was carried out in Boumerdes, a specific viticultural region in Algeria. Soil samples were taken during three periods, before, during, and after treatment with pesticides, using the quadrat method at three soil depths. During these three periods, the soil macro and mesofauna were observed and compared. The results showed significant differences in the composition of invertebrate communities that tended to disappear during pesticide application. The structure and diversity of 11 invertebrate classes, including Collembola, changed along the treatment gradient. The effects of sampling periods on occurrence, abundance, and taxon richness were consistently negative. These indices were significantly lower after pesticide application. Therefore, we can suppose that climatic factors and pesticide treatements are the main factors affecting the activity and density of all classes of invertebrates, but these effects vary between the functional groups of soil biota.

  • Phenology and Diurnal Behaviour of Ruddy Shelduck at Oglat Eddaira (Ain
           Ben Khlil) Wetland, Southwest of Algeria

    • Abstract: The ecological study (phenology and daytime budget) of ruddy shelduck Tadorna ferruginea (Anatidae) at Lake Oglat Eddaira (Ain Ben Khlil), Southwest of Algeria, was carried out for three consecutive years from August 2017 to July 2020. While ruddy shelduck has the status of a sedentary species, it was found all year round, persisting at low numbers in mid-summer months (July–August). The numbers of ruddy shelduck began to increase from the first decade of September with the arrival of the wintering and breeding populations. High numbers of ruddy shelduck were mainly recorded between late January and early March. During our monitoring, the balance sheet of the rhythms of daytime activities was dominated by feeding in water and on banks (68%), followed by preening (16.77%), swimming (9.85%,), sleeping (4.67%) and flying (1.22%). Therefore, we can conclude that Oglat Eddaira wetland plays the role of a diurnal grazing ground for this Anatidae.

  • The Ornithological Zoning of the Azov–Black Sea Dry Steppe Enclave
           of Europe

    • Abstract: The scheme of ornithological zoning of the Azov–Black Sea dry steppe enclave of Europe has been presented in the article based on domination of individual ornithological complexes, depending on the landscape structure of the territory. This enclave is a unique region due to its utmost western location and moderate continental climate. Its typical natural features and factors of their formation have been determined. The anthropogenic transformations of region have been characterized, and peculiarities of landscape changes have been caused by them. It has been found that the agro-landscapes are dominated in the Azov–Black Sea dry steppe enclave by the area. The schemes of physical–geographical zoning have been determined, which are suitable for ornithological zoning of the region; the dependence of composition of ornithological fauna on predominant landscapes has been revealed. On this basis, the scheme of ornithological zoning of the mentioned region has been proposed. The flat interfluve-steppe, stony-steppe, sandy-steppe, floodplain-river, and liman-marine ornithological areas have been singled out and have been characterized. The main differences in the ornithological regions are correlations of predominant and codominant ornithological faunistic complexes, which depend on the area landscapes and natural and anthropogenic transformation of their components; they are relief, soil, water bodies, and vegetation.

  • New Investigation and Challenge for Spatiotemporal Drought Monitoring
           Using Bottom-Up Precipitation Dataset (SM2RAIN-ASCAT) and NDVI in Moroccan
           Arid and Semi-Arid Rangelands

    • Abstract: Remotely sensed soil moisture products showed sensitivity to vegetation cover density and soil typology at regional dryland level. In these regions, drought monitoring is significantly performed using soil moisture index and rainfall data. Recently, rainfall and soil moisture observations have increasingly become available. This has hampered scientific progress as regards characterization of land surface processes not just in meteorology. The purpose of this study was to investigate the relationship between a newly developed precipitation dataset, SM2RAIN (Advanced SCATterometer (SM2RAIN-ASCAT), and NDVI (eMODIS-TERRA) in monitoring drought events over diverse rangeland regions of Morocco. Results indicated that the highest polynomial correlation coefficient and the lowest root mean square error (RMSE) between SM2RAIN-ASCAT and NDVI were found in a 10-year period from 2007 to 2017 in all rangelands (R = 0.81; RMSE = 0.05). This relationship was strong for degraded rangeland, where there were strong positive correlation coefficients for NDVI and SM2RAIN (R = 0.99). High correlations were found for sparse and moderate correlations for shrub rangeland (R = 0.82 and 0.61, respectively). The anomalies maps showed a very good similarity between SM2RAIN and Normalized Difference Vegetation Index (NDVI) data. The results revealed that the SM2RAIN-ASCAT and NDVI product could accurately predict drought events in arid and semi-arid rangelands.

  • Temporal Variation in Pollinators’ Visitation of in a Tropical Urban
           

    • Abstract: Pollinator richness, abundance and visitation frequency may be affected by the abundance of floral resources and abiotic factors, influencing plant reproductive success. We analysed whether the diversity, abundance and frequency of butterfly visitation on Lantana camara vary across the year in a tropical urban landscape and whether this variation in butterfly community influences plant’s reproductive success. A two-period survey, referred to here as rainier and drier seasons, was carried out in 12 spatially independent plants. Five pollination treatments were applied: single visit, hand cross-pollination, hand self-pollination, spontaneous self-pollination and open pollination (control). A total of 15,749 flowers were used for fruit production analysis. Butterfly richness, abundance and the reproductive success of L. camara increased in the drier season. Open pollination was ninefold more reproductively successful during the drier season. Fruit production of hand cross-pollinated plants was threefold higher than open-pollinated plants during the rainier season. No significant difference was found between these treatments in the drier season, attesting the highest abundance of pollination during this period. We provide evidence that changes in the pollinator community affect fruit production. The increase in pollinator diversity allows different visitors to pollinate the plant, increasing fruit set through functional complementarity. This effort establishes baseline data of plant–pollinator interactions for further long-term investigations across different weather seasons. The understanding of L. camara and butterflies’ synergism will support conservation measures of pollinator populations.

  • The Influence of Urbanization on Mammal Diversity and their Population
           Patterns: A Case Study of Tashkent, Uzbekistan

    • Abstract: The article provides a survey of the mammalian fauna and ecology in different habitats across the city of Tashkent that vary in the degree of urbanization. The current mammalian fauna of Tashkent is represented by 32 species; during the city’s development, 9 species have disappeared from the place, either through an anthropogenic impact or having been forced out by alien species. The urban mammalian fauna has increased through arrival of five new invasive species. With the ongoing urbanization, the species diversity of small-sized mammals is decreasing, while their numbers are growing, resulting in simplification of the structure of small mammals’ urban communities and lowering of their biodiversity. The urbanization does not impact the age and sex structure of the house mouse population noticeably. The urban population shows a productivity 1.7 times higher than the wild populations, which is a compensatory response to the relatively high embryonic mortality that is almost totally absent in natural populations. Differences in the morphophysiological indicators of the house mouse synanthropic population and those of populations in the wild are an adaptive response to anthropogenic impact, which appears in the form of more rapid growth, a higher metabolism, exchange of energies, and overall stress load on the rodents in urban biocoenoses. The study showed that the skulls of urban animals grow more rapidly than those of wild mice, while their proportions change following the development pattern of juvenile mice, which suggests that individuals from the Tashkent population can be referred to as rapidly growing animals, with outdoor individuals showing greater relative cranial parameters.

  • Assessment of the impact of urbanisation on agricultural and forest areas
           in the coastal zone of Mostaganem (western Algeria)

    • Abstract: The accelerated and uncontrolled urbanisation in the coastal zone of Mostaganem is exclusively at the expense of agricultural and natural areas and is reflected in the aggravation of their degradation. The study area is a 62-km-long littoral to the west of Mostaganem and includes 11 municipalities. The Corine Land Cover nomenclature was used by exploiting data from Landsat satellite images over a 30-year period. The exploitation of statistics related to agricultural and forestry areas reveals a worrying dynamics. All spaces are under pressure mainly due to urbanisation. The phenomena of urbanization and coastalisation and the development of seaside tourism have increased the pressures on natural heritage to the point of compromising it. The analysis identified seven thematic object classes for the study area. An assessment of the dynamics of urban, forest and agricultural areas is an informative indicator of the sustainability of natural areas in the coastline of Mostaganem. The cultivated areas measured from 42,356 ha in 1985 to 38,301 ha in 2015,forest formations from 8207 ha to 9298 ha and urbanised areas from 2604 ha to 5049 ha. The dramatic land use change stimulated by rapid urbanisation in the study areas has resulted in a fundamental change in the landscape pattern. The thematic maps and the results obtained through different periods show that the predominant agricultural landscape has been gradually converted into urban areas.
