The research was carried out in the north of Samarskaya Luka in May and July 2012–2018. Sixteen bats were captured and tagged with transmitters. Research revealed that tree hollows serve as main roosts for bats. Regular roost switching is characteristic for pregnant and post-lactating female colonies, while lactating females utilize the same roost for nearly the entire lactation period. Evening emergence of bats is highly light dependent and occurs 40 minutes after sunset on average. Female home range size is similar in spring and summer, and averages 430.7 and 401.8 ha, respectively. Regardless of the season, their main foraging sites are forest edges, clearings, and spaces along the vertical tree and shrubbery vegetation structure of the riverbank area. Pregnant and post-lactating females not caring for offspring exhibit similar duration of nocturnal activity. Lactating females forage less and in phases. In late spring, females often hunt in places located over 3 km away from daytime roosts, while in summer they usually forage within 1 km of the roost. The revealed differences in behavior of pregnant, lactating, and post-lactating females are discussed in relation to insect resources and the energy costs of foraging and feeding non-flying offsprings.

In the common vole, the growth rates of pups reared by single females were significantly higher than in the pups reared by both parents, and the presence of the sire negatively affected the growth rates of the young males. As for the bank vole, the presence of the male was found to have no effect on the growth rates of the young individuals. The results of the study indicate a decrease in reproductive success, and, accordingly, in fitness, of males of the species under study, especially in the common vole, if they choose a reproductive strategy based on pair bonding and biparental care.

Kirilyuk","doi":"10.15298/RUSJTHERIOL.20.1.04","DOIUrl":"https://doi.org/10.15298/RUSJTHERIOL.20.1.04","url":null,"abstract":"Mongolian gazelle (Procapra gutturosa) has been recovering in the Zabaikalsky Krai of Russia since 1993–1994. The process, supported by successful conservation measures, was slow at first, but then accelerated rapidly. Establishment of sedentary groups and increase of their abundance on the Russian territory took place with a simultaneous increase of seasonal migrations of transboundary groups. They became annual since 2008. Russian part of the range expanded from 260 km2 in 1998 to 29 700 km2 in 2020. It covers about 90% of habitats suitable for gazelle in the region. In 2019–2020, both the number of antelopes entering Russia and an area they occupy increased the most: not only antelopes wintered in Russia but they also expanded their occurrence on Russian territory during summer time which was unusual previously and led to a rapid increase of resident local groups. Also, barbed wire fence along a state border near the junction of Mongolia and China contributed to increased accumulation of antelopes on the Russian territory. An unusual entry of Goitered gazelle (Gazella subgutturosa) from Mongolia to Zabaikaisky Krai was first recorded in January 2020. The adult male was photographed near Solovyevsk station more than 500 km from the nearest part of its current range. My findings show that Mongolian gazelles rapidly concentrate in a disproportionately small part (4%) of their current range i.e. the steppe part of Zabaikalsky krai of Russia. This concentration increases a probability of human-wildlife conflicts in Russia. Moreover, given the limited area of the suitable habitats and large number of natural and artificial barriers, chances of mass mortality among migrating cross-border groups increase dramatically. The observed processes evidence anthropogenic displacement of ungulates from the Mongolian territory due to a growing depletion of the forage supply and other negative drivers. In particular, climate change can increase the dangerous impact of humans. There is an urgent need to implement effective measures for conservation of Mongolian gazelle, based on regular monitoring of populations’ parameters that serve as indicators of their sustainability.

This paper presents the results of dietary overlap of Cuvier's gazelle (Gazella cuvieri) and two species of livestock to evaluate whether or not they compete for forage. The study was conducted from September 2016 to August 2017 in the Djebel Messaâd Forest, Algeria, using microhistological analysis. The diet of Cuvier’s gazelle and livestock maintained a high proportion of grasses, shrubs and trees. At Djebel Messaâd Forest, of the total 48 food plant species identified in fecal samples, 39 of which were found in Cuvier’s gazelle, 29 and 36 from domestic sheep and goats respectively; 20 genera occurred in the annual diets of both Cuvier’s gazelle and livestock. The principal foods were browses (N% = 52.6) for Cuvier’s gazelle, while the dominant forage species included Stipa tenacissima, Artemisia herba alba, Pistacia terebinthus, Stipa parviflora, Helianthemum sp. The food diversity was invariably high for Cuvier’s gazelle in autumn and generally decreased from winter to summer, we conclude that this gazelle exhibited a higher dietary diversity than livestock. Shared species 21 represented a higher proportion of dietary items for Cuvier’s gazelle (N% = 76.9) than for sheep (N% = 54.0). While shared 28 species, a very higher proportion of those used by Cuvier’s gazelle (N% = 91.4) than by goats (N% = 61.2). Dietary overlap indices confirmed that, livestock had very similar diets. while, both of them had moderate diet overlap with Cuvier’s gazelle.

The prevalence of these characters was found to be significantly different between samples of V. vulpes and mainland V. lagopus, which can be used to determine species in a fossil record. Notably, Commander Islands V. lagopus differ from mainland V. lagopus in most of the characters. However, some characters of Mednyi Island V. lagopus are unique to them and are not found in any other sample. Some samples from Bering Island do not display such specific features. Samples of ancient foxes, V. praeglacialis and V. praecorsac, have also been studied. Primitive features were observed in both V. praeglacialis and V. praecorsac, with the latter exhibiting also a number of advanced features. It has also been found that primitive features are prevalent in the maxillary dentition of V. vulpes. The insular groups of V. lagopus display numerous primitive features, whereas mainland V. lagopus demonstrate a substantial number of advanced characters. This combination of primitive and advanced features is typical of insular V. lagopus and indirectly suggests that these populations have spent a long time in isolation.

Male rutting roaring activity represents an important part of red deer reproduction but there are no methods for unified evaluation of roaring dynamics. This study proposes the criteria for subdividing the entire rut period to phases (start, active, fading), applicable irrespectively to differences in population geographical area, animal density, subspecies or absolute values of call number per hour. With this approach, we estimate stag rutting roaring activity on hourly basis in five populations of red deer belonging to three subspecies by using two spaced automated recording devices per population, recording roars for 5 min/hour, 24 h/day, for 52–60 days of rutting period. Two spaced recorders per population provided similar data on rut dynamics, although absolute values of call number per hour were different. In four of the five study populations, rut period covered approximately the same calendar dates, from the last days of August until the last ten days of October. The mean roaring activity over a rut period differed strongly between populations (from 4– 15 calls/h to 319–377 calls/h). Effects of time of day on roaring activity differed between rut phases. The possible reasons of this variability are discussed. How to cite this article: Rusin I.Yu., Volodin I.A., Sitnikova E.F., Litvinov M.N., Andronova R.S., Volodina E.V. 2021.
