We have reconstructed Elasmotherium’s head based on complete intact skulls morphology analysis. The bony protuberance on the frontal bone was covered with a horny substance that protected the dome’s relatively thin bones. The keratinized cover grew from the base, clearly visible in the lower part of the bony dome, and its top was displaced dorso-aborally. The dome’s inner surface was an overgrown nasal cavity and served to intensify sense of smell, and, possibly, enhance sounds emitted. A relatively small narrow terminal horn-like cornified pad was attached at nasal and intermaxillary bones’ end, it served to loosen and dig up soil for lants’ succulent underground parts searching. Powerful muscles were especially prominent on the neck, they used to carry out lateral and dorsolateral movements of the head.

. The soil hardness inside burrows was studied in the lesser Japanese mole, Mogera imaizumii , to evaluate differences in the hardness of the ground surface, sidewalls, and bottoms of regular burrows (high usage frequency, R b) and temporary burrows (low usage frequency, T b). We analyzed usage frequency at 68 burrow points by setting snare-type tube traps, which triggered responses by the moles, at each burrow point to record the usage of moles without capturing them. These burrow points were classified as R b or T b based on the presence or absence of a response, respectively, sixteen hours after being set; 20 burrow points were identified as R b, and 48 were identified as T b. No differences in the frequencies of R b and T b were observed relation to the depth, which is related to the vertical gradient of hardness. In addition, newly detected burrows were more frequently found to be T b than in R b during early spring to summer, which seems to be related to mole dispersal. Moreover, we measured the soil hardness of the ground surface, sidewalls, and bottoms of the burrows at the 68 burrow points. On comparisons of the relationships between the soil hardness and the burrow usage frequency, we found that the bottoms were significantly harder in R b than in T b. Therefore, the hardness of the bottom soil in R b is considered to have been caused by the frequent treading of mole movements. to the usage

. The article considers the biography of Anna Semyonovna Stroganova (Evdonina) — a specialist in the field of ecology and faunistics of mammals, Candidate of Biological Sciences, a researcher at the Zoological Institute of the USSR Academy of Sciences (ZIN). The article provides information about the family, education at the Leningrad State University (1929–1933), work at the Leningrad Commercial-Biological Zonal Station (1932–1941), and the Zoological Institute of the USSR Academy of Sciences (1941–1961). The nature of A.S. Stroganova’s work is described to study the ecology of commercial mammals and methods for predicting the dynamics of their numbers to justify fur harvesting in the country and quotas for the permissible withdrawal of resources. The period of her life in the ZIN in the first year of the Great Patriotic War, summer evacuation to Elabuga and then to Stalinabad in 1942, work in Tajikistan and return to Leningrad, restoration work at the Institute and scientific activity in the post-war years are considered in sufficient detail. A.S. Stroganova researched the ecology of commercial mammals and devised methods for predicting the dynamics of their numbers. She also studied the faunistics of mammals in the trans-Volga region and the possibility of changes in fauna because of agricultural afforestation and irrigation. A.S. Stroganova published more than 20 research papers. Unfortunately, her life ended way too soon. She only had half a century to live and did not manage to finish many of her projects or publish all of the articles she wrote. How to cite this article: Tikhonova E.P. 2021.

. Long-term monitoring (2015–2019) was carried out on artificial salt licks (a total of 19 in 3 districts). The total monitoring time was 7123 camera trap days. Depending on the place and year of monitoring, from 5 to 33 different individuals were recorded on each salt lick. Six sex and age groups were identified: adult males, yearling males, adult single females, yearling female, adult females with calves, adult females with yearling individuals. All duration data by sex and age groups including "passing" visits have the form of an exponential distribution (λ = 0.029 ± 0.001 min -1 ). The data of the duration of geophagous visits have the form of a gamma distribution ( k = 1.76 ± 0.087; θ = 21.20 ± 1.501 min). European Moose visit salt licks all year round, most actively in May-August. The average duration of a visit is close to half an hour for each of the identified groups (33.7 ± 1.3 min for all groups; clear time of geophagous visit is 33.2 ± 2.8 min). The duration of salt licking and the mineral lick attendance differs between some identified sex-age groups and months. During the days of salt licking, the same individual most often visits the lick several times (1 to 5 visits a day (max 11), on average 1.48 ± 0.39). The activity of visiting salt licks during the day has a pronounced tendency to acquire peak values in the twilight post-sunset and pre-dawn periods. The moose use a third of the month (34.9% ± 20.8% of month) for salt licking, alternating this with various-time periods break. Age and sex competition for the use of salt licks was noted.

We have studied the composition of scats in the free-ranging population of the red fox Vulpes vulpes on Urup Island during the population depression of the island's key prey — the brown rat Rattus norvegicus caraco. The scat samples were collected on the northern and southern points of the island. We determined the occurrence of certain food components and biomass of the different-sized fractions of the faecal particles after sieving. Vertebrates make up a small part of the red fox`s diet, both in terms of occurrence and biomass of the remains in the scats. The occurrence of the micromammals is less than 20%. Bird remains occur in the scats twice as high especially in the northern part of the island, where there are forest communities. Insects and crustaceans have the greatest occurrence and the bulk of the biomass in the faecal fragments. This demonstrates the importance of coastal and tidal habitats for the red fox. The berries of wild shrubs are often found in the scats. The discrete mean (dMean) of faecal particle size is 2.47 ± 0.12 mm for all samples. The dMean value is determined by the proportion of the largest faecal particle fraction. The proportion of the smallest size fraction of particles reliably correlates with the fraction of insect biomass. The negative correlation is found between the proportions of the biomass of insects and crustaceans, and between the proportion of crustaceans and the proportion of plant items in the scats. In the period of reduction and absence of some foods in local island sites, the red fox switches to alternative forages easily, confirming its dietary plasticity and opportunistic omnivory. The importance of certain food items in the fox nutrition and the ecological significance of this mesopredator in the ecosystems of Urup Island have been discussed.

. The occurrence and distribution of ten larger terrestrial mammals on the Ionian Island of Corfu were investigated from January 2020 to March 2021. The northern white-breasted hedgehog and the stone marten were found to be common, and this is probably also the case for the least weasel. The red fox was primarily found in the island’s rocky northeast and although not uncommon it may be under pressure as it is often considered a pest. Wild boars were found to be present, and reproduction may occur, but the status of this species needs further investigation. The Eurasian otter was found in several areas around the island, but the data indicates that the Corfu population contains few individuals that move over large areas. We suggest strengthened protection for this species to avoid further population decline and subsequent extinction. Brown hares of unknown origins are repeatedly released on the island, and in combination with extensive hunting any genetic characteristics of the indigenous population is expected to be lost. No evidence for presence of fallow deer was found, and except for photos of single specimens this was also the case for red deer and golden jackal. All investigated species are potentially threatened by habitat loss, caused by increasing tourism, extensive development, high water out-take and, in some cases, persecution.

The helminth’s fauna of small mammals of the Smolny National Park (Republic of Mordovia, Russia) was studied during 2018–2019. In total, 973 individuals of 14 species of small mammals were trapped, including 9 individuals of Microtus subterraneus (Rodentia, Cricetidae). Four European pine voles were found to be infected by helminths. The helminth fauna of pine voles was analyzed in Russia for the first time. Average abundance of helminths was found as 1.0. Three species of helminths were reported, namely: Anoplocephaloides dentata s. l., Hydatigera taeniaeformis s. l. (larva) and Heligmosomoides laevis. These are known as common parasites of the Microtus voles. The helminth fauna found in Microtus subterraneus is formed by the rodent’s lifestyle, it defined by herbivory of pine voles. The low species richness of helminths in the pine voles may also associated with a small number of animals studied and the low infection level of the rodents is defined by low abundance of this vole species in a wild. The review on the helminth’s fauna in Microtus subterraneus in the European range is presented. To date, 23 helminth species are recorded for the pine voles, namely: Trematoda — 1, Cestoda — 16 and Nematoda — 6. How to cite this article: Kirillova N.Yu., Kirillov A.A., Ruchin A.B. 2021.

To date, 23 helminth species are recorded for the pine voles, namely: Trematoda — 1, Cestoda — 16 and Nematoda — 6. How to cite this article: Kirillova N.Yu., Kirillov A.A., Ruchin A.B. 2021.

Many deer species exhibit typical vigilance behavior as an anti-predator response to human disturbances. However, vigilance behavior in sika deer (Cervus nippon) has not previously been assessed. I explored whether human disturbances increase vigilance in sika deer by comparing their behaviors in two areas with different levels of human activity using camera-trapping techniques. The deer spent a significantly higher proportion of time exhibiting vigilance behavior in the site with higher levels of human activity, supporting my initial hypothesis. In addition, their vigilance increased in winter, possibly due to hunting by humans. How to cite this article: Tsunoda H. 2021.
