Light avoidance in Baikalian amphipods as a test response to toxicants
Contemporary Problems of Ecology - Tập 10 Số 1 - Trang 77-83 - 2017
The dependence between the time of escape of Eulimnogammarus vittatus from light
and toxicants in the medium has been studied. It has been shown that these
amphipods display the most rapid response to light in pure Baikal water.
Toxicants slow down the movement of E. vittatus in the dark. A similar effect
has been observed during the experiments with heavy metals, detergents, and
petroleum product...
Cartographic representation of the distribution of black grouse (Lyrurus tetrix L.) and hazel grouse (Tetrastes bonasia L.) in the West Siberian plain

Long-Term Dynamics of Forest Fires in Southern Siberia
Contemporary Problems of Ecology - Tập 16 - Trang 205-216 - 2023
The research focus. Wildfire is a critical environmental disturbance affecting
forest dynamics, succession, and the carbon cycle in Siberian forests. Forests
of southern Siberia experienced an increase of fire rate. We analyzed spatial
and temporal dynamics of burned area in the southern Central Siberian Mountains.
We considered burning rate within different forest types: dark needle conifers
(DNC...
On the Issue of Ecological Niches of Plant Pathogens in Western Siberia
Contemporary Problems of Ecology - Tập 12 - Trang 667-674 - 2020
This article outlines a systematic and ecological approach to the analysis of
ecological niches of pathogenic plant micromycetes taking into account the
achievements of general and evolutionary ecology and epiphytothiology. The
regularities of the expansion of phytopathogen niches in different ecological
environments are traced. The evolutionarily formed primary narrow ecological
niches of soil mi...
Spatial Variation in the Concentration of Phenolic Compounds and Nutritional Elements in the Needles of Spruce in Northern Taiga Forests
Contemporary Problems of Ecology - Tập 12 - Trang 769-779 - 2020
Patterns of lateral intrabiogeocenotic (between separate elementary
biogeoranges) and interbiogeocenotic variability in the content of secondary
metabolites and nutritional elements in the different-age needles of spruce
(Picea abies ssp. obovata (Ledeb.) Domin) have been studied along the
geochemical transect in spruce forests in northern taiga (Kola Peninsula). The
perennial needles of spruce un...
Reconstruction of palaeoecological and palaeoclimatic conditions of the Holocene in the south of the Taimyr according to an analysis of lake sediments
Contemporary Problems of Ecology - Tập 10 - Trang 363-369 - 2017
A sediment core from Khatanga-12 Lake (Taimyr Peninsula, Krasnoyarsk krai) has
been studied. The 131.5-cm-long core covers ca. 7100 years of sedimentation.
Chironomid analysis, a qualitative reconstruction of the paleoenvironment in the
region, and a quantitative reconstruction of variations of the mean July air
temperature and in the water depth of the lake have been performed using
Northern Russ...
Estimation of the carry-over of substances by dragonflies from water bodies to land in the forest-steppe of West Siberia
Contemporary Problems of Ecology - Tập 5 - Trang 34-39 - 2012
The results of many years’ monitoring of the number and distribution of
dragonflies in the Chany area of the Baraba forest-steppe are presented. An
estimation of the biomass carry-over by dragonflies from water bodies to land
ecosystems is given. The data presented provide evidence of the important role
of dragonflies in the migration of substances from water bodies to land.
Dynamics of Species and Size Structures of Phytoplankton at Different Levels of Bottom-Up and Top-Down Effects in Experimental Conditions
Contemporary Problems of Ecology - Tập 12 - Trang 245-253 - 2019
An experimental study of the impacts of trophic conditions and the activity of
zooplankton and fish on the phytoplankton structure has shown that, at the
beginning of the experiment, the species and size structures of algae were
dependent on the N : P ratio. This parameter causes the differences in
phytoplankton structures between mesotrophic and eutrophic conditions so that,
in mesotrophic condit...
Analysis of sexual polymorphism of the plant from subclass Rosidae in Siberia
Contemporary Problems of Ecology - Tập 5 - Trang 337-342 - 2012
Sexual systems and association with several ecological and life history
attributes were examined for 977 native angiosperms of subclass Rosidae in
Siberia. The majority of angiosperms in Siberia are hermaphrodites (87.7%, N =
867). The most widespread forms of sexual differentiations are andromonoecy,
gynodioecy, and dioecy. The rarest forms of sexual differentiations are monoecy,
trioecy, and and...
Present Range of Tuva Mountain Vole Alticola tuvinicus Ognev, 1950 (Review of Environmental Conditions and Modeling)
Contemporary Problems of Ecology - Tập 12 - Trang 453-463 - 2019
This study analyzes the present distribution of the Tuva mountain voles based on
literary data, museum collections, and our own materials. A bioclimatic model of
potential species distribution has been constructed using 25 localities
identified as having Tuva mountain voles in Russia and Mongolia. It is shown
that the species range of the Tuva voles consists of three large isolated parts:
the nort...
