- 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 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 ...

Changes in the temperature parameters of surface air and the rooting peat horizon, as well as an increase in the degree of decomposition and ash content, a decrease in the bog water level and acidity of the upper layer of the peat ...

- Abstract:
- ... The gray crow stay at the Polar circle latitude in Western Siberia lasts approximately six months, from the beginning and middle of April to the beginning and middle of October. The timing of the arrival of the gray crow to the Lower Ob region shifted to earlier calendar dates from 1970–2017. The breeding season starts in May and lasts 2.5–3 months, until late July. Postbreeding moulting starts in ...

- Abstract:
- ... The annual relative mass of storage organs cycle of Bufo gargarizans in southwestern China was studied from December 2005 to November 2006. We described how those organs changed in response to extreme temperatures. Energy reservation dropped to the lowest levels after dormancy for both sexes, and then increased for period of 4.25 month. However, the mass of these organs dropped again rapidly until ...

Quantitative parameters of cenopopulations of Lobaria pulmonaria, an endangered cyanolichen, have been studied in spruce phytocenoses of Karelia recovering after disturbance through the successional stage of aspen stands for a period ranging from 80 to 450 years. The results show that, as the time since disturbance increases, the total number of L. pulmonaria thalli and the number of colonized sub ...

- Abstract:
- ... Carbon dioxide fluxes from the surface of coarse woody debris (CWD) have been measured in Korean pine forests of the southern Sikhote-Alin mountain range. The seasonal dynamics of oxidative conversion of CWD carbon have been evaluated, and average values of the CO₂ emission rate have been determined for CWD fragments of three tree species at different stages of decomposition. The degree of decompo ...

- Abstract:
- ... The Geographic Profiling (GP) is a data analysis tool that has great potential. Presently, it is used only minimally, and is almost always used “as it is”, independently on other analysis or data processing methods. GP was initially created as a forensic tool, to find the origin of a series of events (crimes) done by a single actor. However, using this method in integration with others, it is poss ...

Microhabitat affinities of sand cat and its den site selection were investigated in Sistan and Baluchistan Province from early 2013 to late 2015 in Semsor area. The data acquired from 29 presence plots of indi ...

No correlation between evenness (dominance) and productivity ...

The period of depression was associated with a significant decrease in the species richness of parasite fauna. Su ...
