Background. Islands of rivers and water reservoirs are objects with quite a large total area. Despite their attractiveness for recreational and economic activities, these objects are little-studied, without legal account and protection. Sustainable management and environmental protection of islands are impossible without taking into account their soil cover – the foundation of island ecosystems. Nevertheless, the soil cover of islands is difficult to investigate due to the ongoing evolutionary processes caused by flooding after reservoir creation. The objective of the research was to reveal the features of soil cover distribution on the territory of the floodplain islands using the analysis of relationships of soil development with the terrain parameters, calculated from the elevation data. Materials and methods. The object of the study is the islands of floodplain genesis, located on the territory of the Kazan region of variable backwater. According to the results of field investigation (57 soil slits were located on the 45 islands and 2 peninsulas), natural soil cover of the island is represented by three soil groups: alluvial sod soils, alluvial meadow soils and alluvial meadow-march soils. To determine the development features of islands soils, 8 terrain attributes were calculated to be used as the predictors in logistic regression analysis. Results. Analysis of the affiliation dependencies of soil profile to one of the three alluvial soil groups showed that particle size distribution plays the key role in genetic features forming due to the impact on the height of a capillary border and as a result, the development of hydromorphic signs. Revealed dependencies from the terrain parameters showed the role of stream distribution in development of alluvial soils. Conclusion. The research results showed the ability of terrain features to characterize the development and evolution of soil cover in the territory of the floodplain islands. The logistic regression analysis showed the relief conditions significant for hydromorphic processes development that on their turn determines the genetic affiliation of soil profile.

This study presents a preliminary analysis of the survival of 428 Steller’s sea eagles in captivity based on the data of the European Studbook of this species. We analysed survival rates of 212 males and 216 females and found that females live 6–8 years longer. This phenomenon is explained by parameterization of Weibull ageing model, which reveals higher rates of ageing in males, while the extrinsic (not related to age) mortality does not differ between sexes. An individual’s ageing is followed by decline in its condition. This process can be traced by changes in fecundity, which gradually decreases after the age of 27. Maximum recorded reproduction age of males and females is 34 and 35 respectively.

. Background. To reveal anthropogenic processes that were directly influencing formation of contemporary forest vegetation in forestry of the Zvenigorod Biologocal Station (ZBS, Moscow region), it is necessary to analyze the 19th century documents. Question of the research is to determine which kinds of land-use are reliably documented, and the general objective is to describe anthropogenic impact on formation of contemporary forests systematically. Materials and Additional information was extracted from published (1870–1899) reports of Forestry Department (Ministry of State Property). The data of forest inventory (1985–1986) were used to demonstrate the former land-use effects in structure of contemporary forests vegetation. Results. For the first half of the 19th century archive documents were found those reflect numerous commercial cuts and annual mowing in forests. In the second half of the 19th century, sizes of clear-cuttings and number of seed trees, leaved behind cuts, were set by state rules of cuts published in 1870; in the same rules, also plowing (and even grain agriculture for several years) on clear-cuttings was recommended to improve tree seed germination. The effects of such land-use ways were detected in spa-tial structure and tree-layer species composition of the contemporary forests. Documents on fire history or purposeful tree planting have not been found yet. Conclusion. It is documented that contemporary forests of the Zvenigorod Biological Station have been formed under impact of cuts and regular mowing. The reported experience of document search and the review of published state forestry standards can be useful for planning further studies on land-use history concerned with other European Russian regions under similar landscape and historical conditions.

Background. As taxonomic character of wing venation in dolichopodid flies is often used in taxonomic studies, more detailed observation including variation in shape and pattern of sexual dimorphism between different generations and between sides of individuals has the potential to shed light on evolutionary trends in the family. Materials and methods. A geometric morphometric analysis was conducted to examine the patterns of wing shape variation in the individual population of Poecilobothrus regalis (Meigen, 1824). ANOVA was used to estimate significance of differences among generations, sexes and sides. CVA was performed to allocate these differences. Degree of asymmetry was computed as difference between sizes of left and right wings. Assessment of differences between values of asymmetry in the groups was taken using t-test. Results. An analysis of the data using the Procrustes method found significant intergenerational differences in wing size and shape, and it was shown that the intergenerational shape variation was partly explained by the allometry. Statistic comparison of the amount and pattern of sexual shape dimorphism among three generations reveals no significant differences. In three cases, significant directional asymmetry was found. Conclusion. A comparison of the intergenerational and intra-generational pattern of shape variation and variation, attributed to directional asymmetry, showed their considerable correspondence. There was no significant evidence that level of fluctuating asymmetry may be a measure of the ability of individuals to cope with environmental conditions.
背景。由于翼脉的分类特征经常被用于分类研究，更详细的观察包括不同代之间和个体之间两性二态性的形状和模式的变化，有可能揭示家族的进化趋势。材料和方法。通过几何形态计量学分析，研究了Poecilobothrus regalis (Meigen, 1824)个体种群中翅膀形状的变化模式。采用方差分析(ANOVA)估计代际、性别、侧面差异的显著性。采用CVA来分配这些差异。不对称程度以左右翼大小之差计算。采用t检验评估组间不对称值的差异。结果。利用Procrustes方法对数据进行分析，发现不同代间翅膀的大小和形状存在显著差异，表明异速生长可以部分解释不同代间翅膀形状的变化。统计比较3代间两性形态二态性的数量和模式，差异无统计学意义。在三个病例中，发现明显的方向不对称。结论。代际和代内的形状变异和变异模式的比较，归因于方向不对称，表明它们具有相当大的相关性。没有明显的证据表明，波动不对称的程度可能是衡量个人应对环境条件能力的一种标准。
