Abstract:
... The α-diversity of the grass layer was compared for communities exposed to Acer negundo and unexposed communities. The communities were aligned by characteristics by their degrees of urbanization, fragmentation, and anthropogenic disturbance. The research was carried out in the city of Yekaterinburg (the southern taiga subzone, Russia) at 13 sites. Each site included two sampling plots: one in com ...

Abstract:
... Communities of soil animals (meso- and macrofauna) in rice paddies tend to be fragmented, and have extremely low abundance. Nevertheless, some groups, such as enchytraeids, may become dominant in flooded conditions, as shown in tropical rice agroecosystems. However, the fauna and functional composition of enchytraeids (Annelida, Clitellata, Enchytraeidae) under such conditions have not yet been st ...

Abstract:
... Special aspects of solving certain key problems in the ecology of Quaternary mammals using materials from the Ural region are considered. Possibilities and limitations accounted for by specific features of the region are analyzed. The nature of “mixed” (mammoth, tundra-steppe, hyperborean) faunas and their diversity are considered in the context of questions related to trends in the dynamics of ra ...

Abstract:
... The spatial distribution of coarse woody debris in pine forests has been studied in the Transvolga region of the Marii El Republic. For this purpose, 30 test plots have been established in pine (Pinus sylvestris) stands of the study region. The results are indicative of a tendency toward the spatial grouping (clustering) of woody debris by fractions, decomposition classes, and stocks along with in ...

Abstract:
... The results of studies on the biomorphological features of 22 plant species growing on the southern coast of the Russian Far East provide evidence for the diversity of pathways of their adaptation to stressful habitat conditions. An analysis of the anatomical and mesostructural characteristics of their leaves has revealed representatives of euhalophytes, crinohalophytes, and glycohalophytes among ...
