Mass mortality events in wildlife are a growing concern. Under conditions of rapid global change, opportunistic responses in bacterial commensals, triggered by environmental stressors, may be increasingly implicated in die‐offs. In 2015, over 200,000 saiga antelope died of hemorrhagic septicemia caused by the pathogen Pasteurella multocida serotype...
The review describes the subject of the UNESCO Man and the Biosphere (MAB) program and how the network of Russian biosphere reserves was developed. The MAB Program is designed to coordinate the efforts of scientists from many countries who conduct fundamental research in order to reduce anthropogenic impact and the gap between consumption and conse...
The paper gives data on the fauna of chigger mites (Thrombiculinae), the ectoparasites of small mammals in Mongolia. The ecological and geographic analysis could reveal the major abiotic and biotic determinants of the spread of the chigger mites and make a map of their potential area.
To identify the main factors that affected a catastrophic decrease in the population of the saiga antelope in the Northwest Pre-Caspian region from 800 000 heads in the middle of the past century to about 5000 heads in Spring 2012, long-term data about the saiga antelope biology and the condition of its habitat were analyzed. The results obtained b...
The study of the current ecology of Mongolian gazelle (Procapra gutturosa Pallas, 1777), a typical inhabitant of steppe ecosystems of Eastern Mongolia, and a comparison of the obtained data with previously collected data are required to improve the Biodiversity Conservation Action Plan for the Daurian Steppe ecoregion, which was included into the l...
At the end of 1950s the population of the saiga antelope (Saiga tatarica) in the North-West Pre-Caspian region counted over 800,000 individuals. Estimates of 2008 suggested that about 18,000 saigas were left, in a reduced range area, and after the severe 2009–2010 winter the population has declined to only 8,000 animals. To understand the present c...
The process of vegetation burning is an essential component in the dynamics of grassy arid ecosystems. An understanding of
the impact of fires on various components of the arid ecosystem is required for scientific, environmental, and management
tasks, and it should be assessed with a high spatial and temporal resolution. This paper presents a metho...
Fire is an important natural disturbance process in many ecosystems, but humans can irrevocably change natural fire regimes. Quantifying long-term change in fire regimes is important to understand the driving forces of changes in fire dynamics, and the implications of fire regime changes for ecosystem ecology. However, assessing fire regime changes...
Satellite telemetry is a powerful tool for monitoring animal movements, and Argos transmitters have been widely used. Unfortunately,
only few studies have systematically evaluated the performance of Argos satellite collars for wildlife monitoring. We tested
Argos satellite telemetry transmitters at two power levels in Southern Russia (five transmit...
Effective conservation requires a good understanding of factors causing variation in population growth rate. We here analyse the relationship between female age and fecundity in the saiga antelope Saiga tatarica tatarica, a critically endangered ungulate of the Eurasian steppes and semideserts, at both individual and population levels. Annual varia...
Effective conservation of exploited species requires an understanding of the motivations experienced by resource users. When use is illegal, it can be particularly difficult to distinguish users from non-users. The attitudes of local people are critical to conservation success, because they interact with social circumstances to determine behaviour....
The possibility of implementing 12 principles of the ecosystem approach is considered with regard to the results of meetings
of the Conference of the Parties to the Convention on Biological Diversity (CBD) and recent international forums. The importance
of these principles for achieving the main goals of the CBD is shown, and the role of biosphere...
Based on the results of analysis of the published and the authors' data, schemes of distribution of the great gerbil (Rhombomys opimus Licht. 1823) subspecies and spatial structure of the whole geographical range of this species were compiled. Historical changes in the distribution and methods for studying various population groups are considered....
In polygynous mammals, males generally benefit more from extra allocation of maternal resources than females. However, limitations to sex-specific allocation are usually ignored. We propose the 'allocation constraint' hypothesis, whereby maternal resource allocation is more likely to follow life-history predictions in single sex litters than in mix...
We analysed the mtDNA control region (HV1) of 93 tissue samples from all five populations of the saiga antelope Saiga
tatarica. The results show a slight but clear distinction between S.
t.
mongolica and S.
t.
tatarica, supporting the current designation of S.
t.
mongolica as a subspecies rather than a separate species. Levels of genetic diversity...
The mitochondrial DNA D-loop hypervariable fragment sequence polymorphism was examined in 27 Mongolian gazelles from Mongolia, Russia, and China. Intraspecific polymorphism of the D-loop fragment examined was demonstrated. All haplotypes described were unique. The average nucleotide diversity (pi) for the mtDNA fragment investigated constituted 5.8...
Using as molecular marker the most variable mDNA segment - left domain of control region (D-loops) able to reflect changes of effective population number (including 'bottle gourd' passing), it is shown that presently in the European population of Saiga antelope, due to catastrophic decline of its number, the decreasing of general genetic diversity...
A common assumption is that breeding in polygnous systems is not limited by the number of males because one male can inseminate many females. But here we show that reproductive collapse in the critically endangered saiga antelope (Saiga tatarica tatarica) is likely to have been caused by a catastrophic drop in the number of adult males in this hare...
The phylogeny of the family Bovidae has been inferred from our data on the 12S and 16S rRNA gene sequences and from the results of other authors. A considerable (2,460 bp) length of the analyzed fragments of these conserved genes and the use of different methods of cladogram construction allowed us to verify the systematic position of the genera Sa...
Data are presented on the changes in distribution and abundance of the Mongolian saiga Saiga tatarica mongolica in the last few decades, based on an analysis of the literature and the authors’ field observations. The subspecies has suffered a considerable decline in its range because of hunting and competition with domesticated stock. In 1997 a sur...
We present new data on the size of all the saiga antelope populations; three populations of the subspecies Saiga tatarica tatarica in Kazakhstan, one of S. t. tatarica in Kalmykia, Russia, and two of S. t. mongolica in Mongolia. The data suggest that three populations are under severe threat from poaching and have been declining at an increasing ra...
The current status of the Mongolian gazelle population is described. The range of this species is located in the territories of China, Mongolia and Russia. Urgent tasks for investigation and conservation of this species within the framework of international cooperation are discussed.
The history of studies of the great gerbil range was analyzed and position of the range boundaries was made more precise on the basis of the published data, museum collections, various natural maps, and authors' field observations. A scheme of the range regionalization is presented, in which three regional complexes of autonomous population groups...

... Опустынивание ландшафтов аридной зоны рассматривается как результат однонаправленного действия комплекса природных (аридизация и засухи) и антропогенных (распашка, выпас скота, ландшафтные пожары) факторов. Численность крупных диких животных -потребителей растительной массы пастбищ в последние десятилетия многократно сократилась, поэтому не может рассматриваться как существенный фактор опустынивания, тем не менее отдельные локальные вспышки численности саранчовых могут существенно влиять на запас надземной фитомассы (Karimova et al., 2021). Воздействие природных и антропогенных факторов на состояние пастбищных ландшафтов достаточно сложно анализировать по отдельности (Золотокрылин, Виноградова, 2007;. ...
... Another question open for discussion is whether the lesions lead to dehydration and disturbed osmoregulation, both crucial for the survival of the animals. New host-parasite association combined with wounded and damaged skin significantly increases the chance of other infections even with opportunistic pathogens (Robinson et al. 2019). In bats, a wide variety of commensal bacterial and fungal species are known to be enteropathogens and have the potential to cause opportunistic infections (Mühldorfer 2013). ...

... A drastic decline of the global population has led to a Critically Endangered listing on the 2002 IUCN Red List (Milner-Gulland et al. 2003). The most recent sudden decline of saiga population in the pre-Caspian has been argued to be caused by a catastrophic drop in the number of adult males owing to selective poaching for the horns (Milner-Gulland et al. 2003;Neronov et al. 2013). In this harem-breeding ungulate, an adult male typically defends a harem of 12-30 females during the rut which takes place in December (Bekenov et al. 1998;Sokolov and Zhirnov 1998). ...
... At present S. t. mongolica and S. t. tatarica are isolated by the Altai Mountain Range, with approximately 1500 km separating them (IUCN, 2018). Current available genetic studies based on the mitochondrial control region (CR) support the split into two subspecies (Kholodova et al., 2006). ...

... a collapse of the state farming systems, and as animals were used as a trade currency by the rural population in times of economic hardship: in Kazakhstan, sheep declined from 36 million animals in 1990 to 9.5 million in 1998 (−73%) and cattle from 9.8 million to 4.0 million (−60%, Kamp et al., 2016). Populations of the most important wild grazer, the Saiga Antelope Saiga tatarica, also collapsed in the 1990s (decline of 96%, Milner-Gulland et al., 2001). This massive loss of grazing animals in less than a decade resulted in a very large decrease of grazing pressure across the Eurasian steppe and was mirrored in adjacent regions of Russia (Dubinin et al., 2010). ...
