  • Estimating Aboveground Forest Biomass Using Radar Methods

    • Free pre-print version: Loading...

      Abstract: The forest biomass dynamics in boreal forests has a significant effect on global carbon cycles. Biomass estimates provide insight into the carbon balance of forest vegetation in Siberia. This paper discusses the methods used in modern studies (2010–2021) to estimate aboveground forest biomass on the basis of radar remote sensing data. Biomass estimation methodologies are described, including field data collection, data preprocessing, and modeling of relationships between remote sensing (RS) data and biomass. In terms of forest biomass estimation, radar sensing has limited capabilities determined by the characteristics of the survey equipment and parameters of studied forest stands. Modern studies combine optical and radar RS data to estimate forest biomass more accurately using regression models, machine learning, and special techniques (BIOMASAR, SWCM, and MaxEnt). Vegetation optical depth values estimated on the basis of microwave surveys make it possible to solve the saturation problem hindering the estimation of large amounts of biomass. It is difficult to compare the accuracy of biomass estimation methods due to the lack of uniform approaches to experimental and error computation procedures. Errors in biomass estimates produced on the basis of optical and radar data vary considerably (~25% on average). The small amount of reference field data complicates biomass estimations in boreal forests of Siberia. It is believed that the application of machine learning algorithms to remote sensing data collected by the Sentinel-1 and ALOS-PALSAR satellites will make it possible to estimate the biomass of boreal forests with a high spatial resolution.

  • Microstatial Distribution of Dung Beetles (Coleoptera: Scarabaeoidea) in
           Horse Excrement in the Southern Sikhote-Alina, Russia

    • Free pre-print version: Loading...

      Abstract: The differentiation by microsites of the population of dung beetles inhabiting horse droppings in the southern Sikhote-Alin, Primorsky krai, has been studied for the first time. The heterogeneity of the substrate has a significant effect on the distribution of beetles among microstations. The key factor affecting the seasonal dynamics of the species composition, abundance, and biomass of beetles in different parts of the droppings are the temperature and humidity regime. It is shown that the confinement of certain species of dung beetles to areas of horse manure can serve as a way of dividing their ecological niches and a way of avoiding competition within one functional group.

  • Enzyme Activity as an Indicator of the Ecological State of Alluvial Soils
           (Using the Example of the Zeya River)

    • Free pre-print version: Loading...

      Abstract: — The regulation of river flows by constructing hydroelectric power plants and dams leads to a significant transformation of the floodplain ecosystems downstream and their components. One way to assess the ecological state of natural landscapes is to determine enzymatic activity. However, the global literature has very little data on the enzymatic activity in floodplain landscapes, not only disturbed but also natural ones. This results mainly from the difficulties of studying floodplain areas, as they are highly dynamic natural objects with strong variations of properties and parameters, both in space and time. In this work, we partially fill in this gap by showing whether the activity of enzymes can be used to assess the ecological state of floodplain soils with the long-term regulation of the river flow. The Zeya River has been regulated by the Zeya Hydroelectric Power Station since 1975. We have determined the activity of enzymes (phosphatases, ureases, catalases, polyphenol oxidases, and peroxidases) in five types of floodplain landscapes: meadow on the riverine floodplain; meadow, arable land, and forest on the central floodplain; and a swamp in the backswamp depression. The high activity of phosphatase (max. up to 10 mg/g) and low activity of urease (max. up to 0.55 mg/g) and catalase (max. up to 0.55 g/cm3) have been determined. The activities of polyphenol oxidase (max. up to 85 mg/100 g) and peroxidase (max. up to 290 mg/100 g), expressed through the humus accumulation coefficient (max. 41%), indicate the average level of floodplain soil fertility. The diversity of enzymes has been evaluated using Pielou’s index and geometric mean. Under the long-term regulation of the river flow, the highest levels of enzymatic activity have been determined for the soils under the floodplain forest and the lowest for arable soils. However, we have not identified a specific soil parameter that would reliably affect all enzymes. Phosphatase, urease, and catalase exhibit significant positive relationships with exchangeable acidity. Catalase has been characterized by strong positive relationships with organic matter and negative with pH. The data allow us to state that the long-term regulation of river flow leads to a decrease in the activity and diversity of enzymes.

  • Spatial-Temporal Dynamics of Evapotranspiration in the Podkamennaya
           Tunguska River Basin

    • Free pre-print version: Loading...

      Abstract: The hydrological role of forest communities dominating in the Podkamennaya Tunguska basin has been assessed by their contribution to the total evaporation in the watershed area based on the landscape differentiation of the region. We have used evapotranspiration parameters obtained by remote sensing data from MODIS Global Evapotranspiration Project (MOD16 ET), which takes into account the climatic data of the studied area, the types of the terrestrial surface, and the diversity of the landcover. The studies show that the evapotranspiration of the specified classes of forest vegetation is characterized by significant variability both in space and with time. The variability of evapotranspiration from year to year is primarily related to changes in meteorological parameters and the leaf index. The evaporation variability in space is determined by general climatic characteristics of the research area and different species composition of forest stands. The analysis of data reveals the tendency to a decrease in the annual evapotranspiration in the Podkamennaya Tunguska basin from 2000 to 2014. A comparative analysis of evapotranspiration trends with those in air temperature and precipitation confirms that the evapotranspiration decrease is related to changes in climatic conditions in the studied area. It is revealed that the landscape structure of watersheds may be used to indicate the processes forming evapotranspiration as an important component of the water balance, as well as to determine the hydrologically significant boundaries of landscapes. The assessment of evaporation from the land surface based on remote sensing data (product MOD16 ET) may be used for water balance calculations in watersheds of various sizes, particularly in the absence of a runoff database.

  • Evaluation of the Water Quality of the Ilke Stream According to Biotic
           Indices Based on Benthic Macroinvertebrates (West Anatolia, Turkey)

    • Free pre-print version: Loading...

      Abstract: Benthic macroinvertebrates can provide an integrated picture of environmental changes. Health of freshwaters can be assessed based on measured changes in the ecological structure of benthic macroinvertebrates. During the study period, 33 taxa were determined in Ilke Stream. As a result of principle component analysis (PCA), mainly nine components (T °C, EC, TDS, BOD5, NH4–N, NO2–N, NO3–N, PO4–P and CI–) account for 92% of the total variance among the water quality parameters. As a result of the UPGMA analysis, the highest similarity value was observed between the 1th and 2nd sampling points. SI, BMWP, ASPT and BBI indices were more proper than FBI index to determine the water quality of Ilke Stream. The results indicate that these indices should be adapted based on the ecological, geomorphological and environmental features of the regions.

    • Free pre-print version: Loading...

      Abstract: This article presents an analysis of the influence of technogenic pollution on the content of biologically active substances and the antioxidant activity of the fruits of Rosa corymbifera Borkh. In a technogenic environment (using the region of Donetsk as an example), an increase in the concentration of anthocyanins, tannins, and oxycinnamic acids and a decrease in the level of flavonoids, ascorbic acid, and polysaccharides have been revealed. Under the conditions of anthropogenic pressure, the content of flavonoids changes most significantly. A significant increase (2 times) in antioxidant activity under conditions of technogenic load is revealed. The interrelation of the content of heavy metals (lead, cadmium, and mercury) in the soil (mobile forms) and fruits is evaluated. The conformity of fruits of R. corymbifera plants growing in the Donetsk region to the requirements of the regulatory documents is evaluated.

  • Seed Longevity in Calcareous Ecosystems

    • Free pre-print version: Loading...

      Abstract: Calcareous lands play an important role in the gene reservoir persistence through soil seed bank (SSB). This research was carried out to assess soil seed bank dynamics (SSBDs) in a calcareous and a non-calcareous land in central Iran through time. Plot-based sampling was done at two times in 6 and 18 months after seed dispersal. Environmental and soil characteristics and diversity and germination indices (DIs, GIs) were measured for SSB. Multivariate ordination (CCA) and liner regression was performed to detect relationship between SSBDs and soil factors. Nitrogen (N), organic matter (OM), phosphorous (P), and soil moisture (SM) affected SSBDs in short time and lime content had a positive effect in persistent SSB in long time, especially in grasses (Sig. < 0.05). In calcareous soil, the lime content showed a positive relation with GIs, where has led to an inducible seed dormancy and preserved vigor index (VI) {R2 = 0.67 and 0.45 in grasses and forbs, respectively} after 18 months.

  • The Accumulation of Cu, Co, and Mg Ions and Its Effect on the Growth of
           Darlingtonia californica Torr. In Vitro

    • Free pre-print version: Loading...

      Abstract: — The response of Darlingtonia californica Torr. on the effect of Cu, Co, and Mg ions in vitro is studied. The following concentrations of mineral salts are tested: 0.1 (control), 10, 25, 50, 75, and 100 μM CuSO4·5H2O (which corresponds to 0.006, 0.6, 1.6, 3.2, 4.8, and 6.4 mg/L of water-soluble Cu ions); 0.1 (control), 10, 25, 50, 75, and 100 μM CoCl2·6H2O (corresponding to 0.006, 0.6, 1.5, 3.0, 4.4, and 5.9 mg/L of water-soluble Co ions); and 1500 (control), 4500, 7500, 10500, and 15 000 μM MgSO4·7H2O (corresponding to 36, 108, 181, 253, and 362 mg/L of water-soluble Mg ions). The results show a direct significant correlation between the accumulation of Cu, Co, and Mg ions in D. californica plants depending on their content in nutrient solutions. The maximum accumulation of ions is found after 45 days of cultivation, Cu—138.24 mg/kg of dry matter, Co—249.92 mg/kg, and Mg—4722.26 mg/kg. It is shown that the concentrations used do not significantly affect the parameters of plant growth and development in vitro. Morphological and anatomical studies confirm the high level of ecological adaptation of this species to extreme conditions. In addition, the plants do not require specific cultural conditions; they are able to grow on nutrient media rich in mineral composition at a temperature of 24 ± 1°C and do not require low positive temperatures for the root system. The results show that D. californica plants are able to accumulate Cu, Co, and Mg ions and tolerate high concentrations of these elements in nutrient media in vitro, but they are not characterized by an increased need for these elements for normal growth and development.

  • Is Water Pollution the Only Cause of Abnormalities of the Attachment
           

    • Free pre-print version: Loading...

      Abstract: A comparative study of the haptoral morphology of three diplozoon species (Monogenea: Diplozoidae) from the gills of fish from polluted water bodies (the Obʼ River and Rybinsk Reservoir, Russia) and the unpolluted Tana Lake (Africa) has been carried out. An examination of the haptors of Paradiplozoon megan (Bychowsky et Nagibina, 1959) from ide captured in the Obʼ River and Rybinsk Reservoir and Diplozoon paradoxum von Nordmann, 1832 from bream from the same water bodies has revealed a large number of abnormalities in the attachment clamps. Different abnormalities in the structure of attachment clamps have also been found in Paradiplozoon spp. from barbels from Lake Tana, which is not exposed to industrial pollution. According to the literature data, abnormalities in the haptor structure have also been found in diplozoons from relatively clean water bodies. Abnormalities, such as the formation of rudiments of the fifth and sixth clamps, have been recorded only in clean water bodies. It is hypothesized that the pollution of water bodies is not the main cause of the formation of abnormalities in the structure of clamps; there is also a natural (“background”) frequency of occurrence of abnormalities in diplozoons.

  • Influence of Abiotic Environmental Factors on the Accumulation of Phenolic
           Metabolites of Dasiphora fruticosa

    • Free pre-print version: Loading...

      Abstract: The composition and content of phenolic compounds in the leaves of Dasiphora fruticosa growing in the Far East and Southern and Eastern Siberia in the range of 43°13′–62°52′ N has been studied. The phenolic complex of D. fruticosa is composed of 16–22 components and remains constant. Its variation is caused mainly by minor components. Seven flavonol glycosides (hyperoside, isoquercitrin, rutin, avicularin, quercitrin, astragalin, and kaempferol-rutinoside), two aglycones (quercetin and kaempferol), and ellagic acid and its glycoside have been found using HPLC and UV spectrometry. The total content of phenolic compounds in plant leaves ranges from 13.5 to 28.3 mg/g, the content of quercetin glycosides ranges from 4.8 to 17.3 mg/g, and the content of kaempferol glycosides ranges from 0.1 to 1.3 mg/g. The total content of ellagic tannins in the leaves varies from 6.9 to 12.9 mg/g. It is found that the content of all individual components increases except for avicularin (which, on the contrary, decreases) as D. fruticosa moved from south to north with insolation on the background of low-temperature stress and drought. It is shown that the content of phenolic compounds (in total and in groups) is determined by temperature (by 53–75%) and the content of flavonols by drought (50–91%) and solar radiation (50–54%). The accumulation of ellagic compounds in leaves of D. fruticosa is 60% determined by temperature; other factors are of low importance. Air temperature, drought, and UV radiation make a significant contribution to the accumulation of phenolic compounds in D. fruticosa.

  • How the Physical Properties of the Leaves of Common Plants Affect
           Dependent Acoustic Characterization in Urban Areas of Istanbul, Turkey

    • Free pre-print version: Loading...

      Abstract: To date, several ecological studies have addressed the influences of environmental noise. However, fundamental studies on noise reduction depending on the acoustic characterization of natural materials are still lacking. The present study quantitatively evaluates experimental data on sound absorption and attenuation of untreated plant leaves commonly found in urban areas. The leaves of English Ivy (Hedera helix L.), Horse Chestnut (Aesculus hippocastanum L.), Hortensia (Hydrangea macrophylla (Thunb.) Ser.), Japanese Privet (Ligustrum japonicum Thunb.), Laurel (Laurus nobilis L.), Linden (Tilia tomentosa Moench), Magnolia (Magnolia grandiflora L.), Osmanthus (Osmanthus heterophyllus (G.Don) P.S.Green), Plane Tree (Platanus orientalis L.), and Cherry Laurel (Prunus laurocerasus L.) were collected from branches of healthy plants grown under identical climate and soil conditions. To acoustically characterize plant leaves, impedance tube and pulse-echo techniques were used to experimentally determine the normal incidence sound absorption coefficient (SAC), speed of sound and sound attenuation coefficient (SC) values, respectively. In addition, as more effective numerical outputs, the normalized SAC (SAC′) and normalized NRC (NRC′) values were calculated by empirical modelling. As a statistical approach, multiple regression was also conducted to predict the dependent acoustic variables based on the independent physical parameters of the samples.

      Abstract: As birds adapt to life in urban areas, separate urban populations are formed which are, in regards to many biological and ecological characteristics, distinct from birds of the same species that inhabit natural environments. The woodpigeon is one of the most common representatives of synurbic bird species that has successfully managed to spread to cities in most of Europe over the past century. This article explores the history of formation of synurbic woodpigeon groups in Belarus and looks at the differences in the breeding biology of forest and urban birds based on research in 2000–2021. During this period, we collected information about 109 woodpigeon nests in forest areas and 368 nests in urban areas. In the course of our research, we found out that the synurbic woodpigeon continues spreading to northern and eastern parts of Belarus. By now, urban birds live in around 70% of the entire territory of the country. Our analysis of the woodpigeon breeding biology shows that there are differences between forest and urban birds that stem from the fact that the latter live in urban areas. Despite the absence of clear differences in the phenology of the arrival of the woodpigeon in cities and natural landscapes, the nesting period of urban birds starts earlier and lasts much longer. In addition, the share of birds that breed more than once per season is larger than in forest birds. The peculiarities of nesting sites observed in urban birds as opposed to wild birds result from the peculiarities of urban green spaces and the effect of predation. We discovered that the share of nest failures peaks in spring (April–May). The breeding success of the woodpigeon in urban areas amounts to 52% of all nesting cases.

  • Territorial Heterogeneity of the Earthworm Population (Opisthopora,
           Lumbricidae) of Omsk Oblast and Environmental Factors: A Quantitative
           Assessment of the Relationship

      Abstract: — According to the results of 9 years of earthworm collections in soil in Omsk oblast from 2009 to 2018, their population has been analyzed in order to identify the main environmental factors associated with the territorial heterogeneity of species richness and group density. Five types of Lumbricidae populations have been identified, two of which are divided into two subtypes, where ten species and two subspecies of earthworms are found. It has been established that environmental factors such as zonality and subzonality; the depth of the soil layer; and, to a lesser extent, the topography characteristics have the greatest influence on the distribution of worms: 9, 7, and 0.7% of the considered variance of the density similarity matrix, respectively. In general, all environmental factors and their combinations (modes) explain 38% of the considered variance; the multiple correlation coefficient is 0.62. Dendrobaena octaedra (7–52%) and Aporrectodea caliginosa (15–74%), alien species of European origin, and the native Eisenia n. nordenskioldi (6–28%) took over in terms of the share of the population density in most taxa of the classification, as well as Eisenia ventripapillata (42%) and E. nana (16%) of Asian origin, for the territories of the southern forest steppe and steppe. Such changes in earthworm populations, namely the replacement of native species of the Eisenia nordenskioldi complex with alien species, can significantly affect soil characteristics and ecosystem services determined by earthworms.

  • Impact of Climate Change on Ecosystem Productivity of the Belarusian
           Polesia According to Remote Data

    • Free pre-print version: Loading...

      Abstract: The results of an analysis of changes in the productivity of forest, swamp, and arable ecosystems in the eastern part of the Belarusian Polesia in 2000–2020 are presented based on satellite imagery (the MODIS radiometer of the Terra satellite). The normalized difference vegetation index (NDVI) was used to evaluate productivity. The correlation between changes in climate indicators and the NDVI has been studied. It is established that the ecosystems differ in their response to climate change. Statistically significant positive NDVI trends are found for forest and wetland ecosystems. No reliable correlation between this indicator and the average summer temperature and the amount of summer precipitation has been established. Arable ecosystems are characterized by the absence of a statistically significant trend in productivity and a significant negative correlation of the NDVI with temperature and a positive one with precipitation. The influence of climatic characteristics on the NDVI of arable ecosystems depends on their soil type.

  • Genetic Diversity of Nitraria sibirica Pall. (Nitrariaceae) in the
           Populations of Siberia and Kazakhstan Based on the Polymorphism of
           Intermicrosatellite Markers

      Abstract: The authors have investigated the diversity of Nitraria sibirica by the ISSR-PCR method in 22 natural populations of Altai krai, the Republic of Altai, and the Republic of Kazakhstan. When primer UBC-807 is used, the number of amplified DNA fragments is 16 and their sizes vary from 200 to more than 1000 bp. The number of polymorphic loci is 14 and their proportion is 87.5%. A high level of interpopulation differentiation is revealed for N. sibirica. The interpopulation component accounts for 68% of all variability. The Nei genetic distance (D) between samples within populations does not exceed D = 0.14. Interpopulation distances vary within D—0.11–0.50. In total, 14 variants of the genotype have been found which are divided into 2 groups: Siberian and Kazakhstan. The maximum genetic differences are recorded in Kazakhstan samples Nitraria from the Koktal population, which may be a consequence of the ecological and geographical differentiation of N. sibirica in the extra-arid conditions of the Ili Basin.

  • Climate Changes in Central Asia as a Prerequisite and Trigger of Plague
           Microbe (Yersinia pestis) Speciation

    • Free pre-print version: Loading...

      Abstract: Two physical and climatic factors that were distant and recent prerequisites and a transformation trigger for a clone of the ancestral pseudotuberculous microbe Yersinia pseudotuberculosis O:1b (the causative agent of the Far East scarlet-like fever (FESLF)) into a population of the plague microbe derivative Y. pestis are considered. One remote prerequisite was the aridification of the Central Asian landscapes in the second half of the Cenozoic period and the formation of the Gobi Arid Zone. The arid conditions of Central Asia determined the formation of adaptive species-specific protective behavior in the Tarbagan marmot (Marmota sibirica) when installing the plug of a wintering hole, which later contributed to the massive infection of the animals with FESLF by the aberrant (traumatic, not alimentary) method during hibernation. A recent prerequisite and a real trigger of Y. pestis speciation was the onset of the last maximum (Sartan) ice age in Central Asia at the turn of the Pleistocene and Holocene, 22 000–15 000 years ago. Freezing of the cooling burrows of the Tarbagan marmot caused a behavioral shift in the larval population of the marmot flea Oropsylla silantiewi and the transition to the cold winter–spring months of the year from saprophagy in the nesting litter to hematophagy on the bodies of sleeping animals. Larval scarifications in the oral cavity of sleeping marmots have become the entrance gate for a unique traumatic FESLF infection. The constellation of climatic changes, the heterothermal (and, accordingly, heteroimmune) condition of the family groups of sleeping marmots, and the year-round propagation of marmot fleas in wintering burrows, combined with behavioral shifts in marmots and fleas caused by climatic changes, led to the formation of conditions in the parasitic system M. sibirica–O. silantiewi in which the transformation of the FESLF microbe into the causative agent of the plague occurred according to peripatric speciation. Thus, the climatic changes that happened at different times in the Cenozoic initially led to a shift in behavior of the Tarbagan marmot and, subsequently, to a shift in the behavior of the fleas parasitizing it. Ultimately, the change in the behavior of marmots and fleas caused the transition of the clone(s) of the FESLF causative agent into a new ecological niche and adaptive zone, as well as the transformation into a population(s) of the plague microbe.

  • Leading Factors of the Dynamics of Lake Ecosystems under a Changing
           Nutrient Load: Analysis of Long-Term Monitoring Data of Naroch Lakes

    • Free pre-print version: Loading...

      Abstract: Since the second half of the 1970s, the ecosystems of lakes Batorino, Myastro, and Naroch have undergone anthropogenic eutrophication, targeted deeutrophication, and benthification caused by the introduction of the filter-feeding mollusk Dreissena polymorpha Pallas. The set of continuous series of seasonal mean values of eight parameters of each ecosystem obtained in 1978–2015 have been analyzed by mathematical-statistical methods of principal components (PCA) and singular spectra (SSA). The analysis showed that the complicated long-term dynamics of the set of the chosen parameters of the ecosystems was described during this period of time by three principal components by 92% and 90% for Lake Batorino and Lake Myastro, respectively, and by five principal components by 94% for Lake Naroch. We propose a biological interpretation of these principal components, i.e., a hypothesis of the factors exerting the greatest effect on the ecosystem dynamics during those years. The first main factor, which determines the dynamics of the ecosystems of lakes Batorino, Myastro, and Naroch by 63, 65, and 43%, respectively, is interpreted as the resistance of the lake ecosystem to a variable biogenic load, which is inversely related to the trophicity of the reservoir. The second main factor, which contributes 21, 15, and 22% to the dynamics of the ecosystem parameters of Naroch lakes (in the same order), was interpreted as solar radiation activity. The interpretation of the third main factor depends on the properties of a particular ecosystem. For ecosystems that are not deficient in biogenic elements (lakes Batorino and Myastro, with a contribution of the factor to the ecosystem dynamics of 8 and 10%), this may be the transfer of the primary organic matter to consumers of the next trophic level related to the structure of the food chain in the ecosystem. For an ecosystem in which the process of primary production formation is limited by the available amount of biogenic elements (Lake Naroch, in which the contribution of the third main factor to ecosystem dynamics is 13%), this very factor is the third main one, affecting the ecosystem long-term dynamics. The fourth main factor, which determines the dynamics of the Lake Naroch ecosystem by 9%, is also related to the process of primary production formation. Only the fifth main factor, which determined 7% of the dynamics of the ecosystem of Lake Naroch during the analyzed time period, controls the transfer of primary production to consumers of the first trophic level. Thus, our statistical study not only confirmed empirical regularities of the functioning of lake ecosystems, but for the first time enabled us to obtain quantitative assessments of the importance of each main factor for ecosystem development under specific conditions, depending on the trophicity of the water body.

  • Ecological State of Larch Forests in the Forest-Tundra Ecotone of Western
           Siberia (As Exemplified by the Mongayurbey River Valley)

    • Free pre-print version: Loading...

      Abstract: Based on remote sensing and tree-ring chronology data, the ecological state of the extrazonal sparse larch forest in the Mongayurbey River valley (Taz Peninsula) has been studied. This area is one of the northernmost enclaves of taiga vegetation in Western Siberia. An analysis of Terra-MODIS satellite images from 2000 to 2020 shows that the value of the normalized difference vegetation index (NDVImean), which reflects the average amount of photosynthetically active phytomass for the summer period, most strongly depends on air temperature (correlation coefficient R = 0.69). However, despite the steady trend towards an increase in the avarage annual summer temperatures, no statistically significant trend in the vegetation index is found, which is due to the inertness of the shrub–moss–lichen ground cover. An analysis of the relationship between the maximum normalized difference vegetation index NDVImax and the absolute tree ring width (TRW) in Larix sibirica Ledeb. shows a strong correlation (R = 0.72) in the marginal, near-watershed area, where a young forest stand with the highest crown density and abundant undergrowth is located. In the valley areas, conversely, forest-stand digression associated with the deterioration of natural conditions is seen (changes in drainage, soil characteristics, and permafrost-geochemical conditions). With continued warming, the spread of the larch forest from the river floodplain to the watershed can be expected, which confirms the current shift of the forest vegetation boundary to the north.

  • Ecological Niches of Fusarium poae (Peck) Wollenw. in Western Siberia

    • Free pre-print version: Loading...

      Abstract: Fusarium poae (Peck.) Wollenw. is a dominant member of pathogenic mycocenoses of host plant organs in Western Siberia. The underground organs of host plants are its main first-order ecological niche, where this plant pathogen realizes T and R tactics, while generative organs are an auxiliary one. The S tactics are realized in second-order ecological niches, such as soil (main) and seeds (auxiliary). The level of realization of the F. poae ecological niche in underground plant organs depends on a number of factors, among which the main roles are played by the host plant resistance, the hydrothermal conditions of vegetation, soil suppressiveness, and interspecific relationships with other plant pathogens. Under certain conditions, F. poae loses its dominance; by the end of the growing season, it can be completely displaced from the underground organs of plants by its competitors, Bipolaris sorokiniana Sacc. Shoem. and F. oxysporum Schltdl. The maximum (up to 100%) overlapping of ecological niches in terms of the frequency of a joint occurrence has been observed for F. poae and F. oxysporum, indicating sharp competitive relationships between them. The minimum overlapping (5–10%) has been revealed for F. poae and F. sporotrichioides Sherb., as well as F. sambucinum Fuckel. The influence of the year of observations on the suppressiveness of a rhizosphere soil towards F. poae at different plant development phases varies from 29.2 to 90.9% and is statistically significant at a significance level of 0.01. The correlation coefficients between the variety-induced soil suppression towards F. poae and its representation in pathogenic complexes at different vegetation phases vary between –0.546 ± 0.216 and ‒0.765 ± 0.152 (p < 0.05). A study of interpopulation relationships shows that F. poae is antagonistic towards F. oxysporum, F. solani Koord., and B. sorokiniana and neutral with signs of competition towards F. equiseti (Corda) Sacc. and F. sambucinum. The realization of an auxiliary first-order ecological niche of F. poae in the generative organs of plants is determined by seasonal conditions and the structure of generative organs of host plants.

  • Effects of Small Mammals on Broods of Ground Nesting Passerines in Alfalfa
           Fields

    • Free pre-print version: Loading...

      Abstract: Most of the changes in land use have led to a decline in the biodiversity of agricultural land. Extensive perennial alfalfa fields favor the proliferation of agricultural pests, especially common voles. However, rodents can damage not only the plants but also the nests of passerines that breed on the ground. Their seasonal and annual dynamics influence the breeding success of ground nesting passerines, thereby influencing their global populations. We assumed that the number of rodents is higher on perennial alfalfa fields and the ground nests of passerines breeding there are less likely to survive than on a newly established field. Furthermore, we also presumed that the predation pressure inside the plots is lower than at their edges, as more rodents tend to be at the edges of the plots and in the hedges. We tested our hypotheses by trapping small mammals and using artificial ground nests with plasticine and quail eggs. The survey was carried out in the spring of 2017 on large plots of agricultural land in the southern part of Hungary, near the Croatian state border, in the vicinity of Püspökbóly settlement. Contrary to our expectations, the abundance of small mammals was similar in two-year-old (3 individuals per 100 trap nights) and one-year-old (2.5 ind. per 100 trap nights) alfalfa fields. The majority of rodents (more than 86%) were caught near the edges of both plots. The nest predation study lasted for two weeks as the incubation time for ground nesting passerines. From the total of the 80 nests, only in 14 artificial nests (17.5%) was a predation event observed. At the edge of the two plots, where the abundance of rodents was high, the survival chances of the ground nests were similar. In contrast, the daily survival rate of ground nests inside the two-year-old alfalfa plot (99%) was significantly higher than in the one-year-old one (96%). The daily survival rates of nests inside and at the edges of the plots were similar. Besides the small mammals, the nests were also predated by red foxes and birds, therefore there were no differences between the predation activity of rodents and the survival of eggs in artificial ground nests.
