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
S. A. Abramov, N. V. Lopatina, I. V. Moroldoev, Yu. N. Litvinov
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...... hiện toàn bộ
Microscale Heterogeneity of Floodplain Meadows (Using the Example of the Delta of the Northern Dvina River)Contemporary Problems of Ecology - Tập 11 - Trang 35-44 - 2018
T. A. Parinova, A. G. Volkov, A. A. Popova
This article provides a quantitative evaluation of aspects of the spatial heterogeneity of soil and vegetation cover of floodplains in relation to the microrelief using the example of floodplains of the Northern Dvina River delta. It is detected that the soil and vegetation cover of the floodplain meadows in the Northern Dvina Delta is a feature of a relief on a microlandscape level. This dependen...... hiện toàn bộ
Communities of Saproxylic Beetles of Silver Birch (Betula pendula Roth.) in the Voroninsky Nature ReserveContemporary Problems of Ecology - Tập 15 - Trang 71-82 - 2022
A. N. Volodchenko, D. G. Seleznev
This study has been conducted to examine the diversity and community structure of saproxylic beetles inhabiting silver birch (Betula pendula Roth) in the Voroninsky State Nature Reserve. The beetles were caught using interception traps located on the trunks of birch trees in different decomposition stages. The results show that a total 1806 individuals of saproxylic beetles, belonging to 96 specie...... hiện toàn bộ
Reaction of coniferous trees in the Kuznetsk Alatau alpine forest-tundra ecotone to climate changeContemporary Problems of Ecology - Tập 8 - Trang 423-430 - 2015
I. A. Petrov, V. I. Kharuk, M. L. Dvinskaya, S. T. Im
In recent decades there has been an increase in the radial growth of Larix sibirica Ledeb., Pinus sibirica Du Tour, and Abies sibirica in the Kuznetsk Alatau alpine forest-tundra ecotone. Larch growth correlates positively with summer temperatures; cedar and fir growth is determined by temperature, precipitation, and sunshine duration. It is shown that the current growth of maturing larch trees is...... hiện toàn bộ
Health of Vegetation in the Area of Mass Outbreaks of Siberian Moth Based on Satellite DataContemporary Problems of Ecology - Tập 12 - Trang 743-752 - 2020
S. V. Knyazeva, N. V. Koroleva, S. P. Eidlina, E. N. Sochilova
This paper presents the results of analyzing the state and dynamics of damaged vegetation from satellite images of high and ultrahigh spatial resolution. This study was conducted based on the example of the site of coniferous forests in the Lower Angara region (Krasnoyarsk krai), where a large outbreak of the Siberian moth took place in 1944–1995. The remote assessment of the state of dark conifer...... hiện toàn bộ
Morphological, Physiological, and Biochemical Characteristics of Adaptation of Calcephytes of the Genus HedysarumContemporary Problems of Ecology - Tập 14 - Trang 465-471 - 2021
O. A. Rozentsvet, E. S. Bogdanova, G. N. Tabalenkova, S. N. Rozina
The morphological and physiological biochemical features of calcephytes Hedysarum grandiflorum Pall. and Hedysarum gmelinii Ledeb are investigated. The H. gmelinii plants are grown on a more moisturized and saline soil substrate. The leaf parameters of H. grandiflorum plants are characterized by a greater thickness and area and contained significantly more water compared to the leaves of H. gmelin...... hiện toàn bộ
Experience of a Synthetic Approach to an Ecological Classification of Vascular EpiphytesContemporary Problems of Ecology - Tập 12 - Trang 434-443 - 2019
N. M. Derzhavina
On the basis of an investigation into epiphytic ferns and taking into account the literature data, information on ecological classifications of vascular epiphytes has been summarized and a multiple ecological classification is proposed in which vascular epiphytes are grouped into three blocks of morphofunctional types (MFT): facultative epiphytes (protoepiphytes), obligate epiphytes (holoepiphytes...... hiện toàn bộ
