- Abstract:
- ... The article presents long-term (from 1996 to 2018) data on the distribution of burbot larvae at the endogenous-feeding stage during downstream migration in a stream of spawning tributaries of the Ob River: the Severnaya Sosva River (16 years of observations), the Sob River, and the Voikar River (one year of observations). The assumption that the predominance of larvae in the flow horizons depends ...

- 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 ...

In this study, the effects of warming on growing season CO₂ exchange in an alpine tundra ecosystem were examined with closed transparent chamber attached to an infrared gas analyzer. Compared to ambient controls, open-top chambers (O ...

We suggest the concept of ecogeographic aggregations (EGAs) of plant species, according to which populations (ecogeographic units, EGUs) of each species are combined into spatially close groups (aggregations) if they are adjacent to each other and live under similar conditions. The specification of EGA is based on the analysis of thematic geographic maps (of soils, topography, etc.). The delineate ...

The aim of the study was to verify a hypothesis that the proximity of different ecosystems have an impact on the richness of flora in three forest patches in the Choszczno Forest Inspectorate (West Pomeranian Province in NW Poland). Between 2013–2015, the survey involved three areas with different adjacent ecosystems: forest, built−up area, and grassland. At each object we analyzed four test plots ...

- Abstract:
- ... Modeling of the bioclimatic niches of the complex of tall herb communities in the current and predicted climatic conditions by 2070, as well as in the conditions of the climate of the Last Glacial Maximum (about 21 thousand years ago), has been performed. The most important bioclimatic parameters controlling the geographical distribution of tall herbs are the amount of snow precipitation (snow dep ...

The material for the study was obtained from report forms collected in the course of national census of Eurasian Woodcock during the evening roding period in 2016 (2001 forms) and 2017 (2538 forms). The numbers of reported contacts with roding birds reached 14242 and 17 024, respectively. For the first time, a geostatistical kriging method was applied to this large amount of material to describe t ...

A comparative analysis of the seasonal formation of tree rings has been performed in Siberian larch (Larix sibirica Ledeb.) and Scots pine (Pinus sylvestris L.), growing in the southern taiga of Central Siberia in two sites on the altitudinal transect (200 and 536 m a.s.l.). Core samples were taken from April to September in 2012. The results have shown that the onset and duration of different pha ...

It has been found that they could reach this region not earlier than 6500–7000 years BP, i.e ...
