The purpose of this work is to investigate the divergence of the brain’ size and shape of three vole's taxa of “guentheri” group using geometric and linear morphometric analysis. The obtained data show that the sex factor does not affect the brain's linear parameters and shape of the studied taxa that indicates a weak effect of the sexual selection on morphological adaptation and variability of the brain structure. The linear measurements of the investigated taxa differ significantly by all signs (24 parameters). The obtained data indicate that the divergence of Microtus guentheri and M. hartingi is the most significant (92%) that obviously is associated with ancient isolation of this species by Anatolian Diagonal. The differences between the two subspecies (M. hartingi hartingi and M. h. lydius) are much smaller — 63%. It should be noted that the vole of the Strandzha Mountain — M. h. strandzensis differs from the M. h. hartingi and M. h. lydius significantly more — 82 and 75%, respectively. These differences may reflect the history of the investigation of voles from Anatolia to Europe. Geometric deformities of the brain of all taxa are found. Analysis of canonical variations showed that all three taxa differ significantly, both laterally and dorsally. Comparison of taxa lateral views showed that M. h. lydius brain is more flatten than M. h. hartingi, but M. guentheri has a broader brain and a smoother outer olfactory tract as well as smaller olfactory bulbs. By dorsal view, deformation of M. guentheri brain at the attachment sites of the cerebellum hemisphere to the cerebral hemisphere is observed, while the cerebellum worm of M. h. lydius is more flattened. The factors affecting the diversity of brain complexity could include allometry, phylogeny and natural selection. The accelerated morphological evolution of the “guentheri” group can be explained by the fragmentation of the range and habitats.

Intraspecific variation in body weight is a common phenomenon in many mammals and is largely related to variation in quality and abundance of foods. The amount of food in the spring–summer period may affect the growth of the young animals and in winter time affect the fat reserves both affecting the body weight. In this study I examined the winter body weight in adult red foxes Vulpes vulpes in five areas in Scandinavia. The amount of food varied strongly between years in the three northern areas. The winter body weight also varied between years, but this was not a result of that foxes in years with plenty of food were fatter. The reason was differences between years in the proportion of foxes born in years with varying amount of voles. Foxes in the north down to the central part of Sweden are of the same size at least the phenotypes. In spite of that foxes are heavier southwards. The reason is that foxes in the north have thinner bones, probably an adaptation to the amount of snow. In Scania in the most southern part of Sweden the foxes are the largest in Scandinavia and therefore the heaviest. Danish foxes are not as heavy as foxes in Scania. When studying the weights of wild animals in areas where food sometimes is extremely scarce, such as near the limits of the species range, it is important to treat data from different birth cohorts separately. To ignore that may result in misleading conclusions. How to cite this article: Englund J.K.Å. 2020.

The size of mammals is often given as the head and body length (HBL). The condylobasal length of the skull (CBL) is also used as a measure of the size of mammals. The HBL in small mammals is mostly measured from the tip of the nose to the root of the tail. In species like whales, human beings and elephants, the measurements are not comparable with those from small mammals which in fact does not matter. On the contrary, it is of prime importance for the measurements taken within the same species to be comparable. If we deal with incomparable data from different authors or museums, it may result in false conclusions. In the present paper this problem is illustrated by the red fox Vulpes vulpes. The HBL in Scandinavian red fox is 4.43 to 4.54 times the CBL. Data in the literature indicates that European foxes outside Sweden have a HBL 4.54 to 4.96 times their CBL. The difference is probably an artifact of different measuring techniques. Therefore we believe that CBL gives better information about the size of the foxes. However, the length of the skull is far from ideal here, since the proportion HBL/CBL seems to vary geographically. We suggest that what has been measured and how the measurements have been taken must be carefully reported by the authors. The scientists would know then which data can certainly be used for an extended meta-analysis. How to cite this article: Englund J.K.Å., Elmeros M., Österdahl L.E.W. 2020.

In the Gobi region of Mongolia, mining activities have developed rapidly over the last 20 years. The development of the mining sector is important for the economic growth of Mongolia, but local communities have always been critical of its negative impact. The purpose of our study was to determine the mining effects on the small mammal community in the Gobi region. In order to achieve this goal, we estimated the species diversity and abundance of small mammal populations in the vicinity of the Tavan Tolgoi and Oyu Tolgoi mines in Umnugobi aimag of Mongolia in August 2017 and in August 2018. Generally, mining activities in the Gobi region have negative impacts on small mammal communities, and at the same time effects differ on the different species of small mammals.

The current evidence confirms the presence of only one species of spiral-horned antelopes, Pontoceros ambiguus, in the Tamanian (late Early Pleistocene) faunal complex of Eastern Europe. The re-study of fossil materials revealed that the horn core from the Tsimbal locality (Sennaya) on the Taman Peninsula (Russia), previously identified as Tragelaphus sp., belongs to an antelope of this species.

The management of biological resources, which have important utilitarian value, should be based on current knowledge about their distribution, abundance, and taxonomic status. The data on the dynamics of distribution ranges and species abundance are easily available in the literature. However, it would seem that the simplest information — the lists of game species and their regional differences — is difficult for mammalogists to access. We compared the modern lists of hunting mammals of Estonia, Latvia, Lithuania, Poland, Belarus, and the bordering region of the Russian Federation with respect to their quantitative composition, structure and taxonomic verification. General trends and national features of the lists are noted. The recent and historical changes in the lists of objects of legal hunting are analysed.

The acoustic communication in four species of voles of the subgenus Alexandromys (Microtus oeconomus, M. limnophilus, M. maximowiczii, and M. middendorffii) includes two signals: squeaks in the context of discomfort, and singing during courtship for the female. Comparison of signal parameters shows a rather large similarity in the structure of sounds, especially between the lacustrine and Middendorf's voles, the squeaks of which have almost no differences in characteristics when using discriminant analysis. The most different in the squeak parameters is the root vole, which has recently been included in the subgenus Alexandromys. Singing is the most characteristic element of sexual behavior among species of the subgenus along with other behavioral characteristics of species and is used by animals more often than voles of subgenera Microtus and Sumeriomys.

四种亚属田鼠(Microtus oeconomus, M. limnophilus, M. maximowiczii和M. middendorffii)的声音交流包括两种信号:不适时的吱吱声和雌性求偶时的鸣叫。信号参数对比表明，在声音结构上有相当大的相似性，特别是湖田鼠和米登多夫田鼠之间，用判别分析时，两者的吱吱声特征几乎没有差异。在吱吱声参数上最不同的是根田鼠，它最近被纳入亚属Alexandromys。鸣叫是该亚属物种中最具特征的性行为特征，与其他物种的行为特征一起，动物使用鸣叫的频率高于鼠亚属和Sumeriomys的田鼠。本文出处:Rutovskaya M.V. 2020。四种亚属Alexandromys的声通讯研究//俄罗斯J.

Field surveys of mammals in two protected areas of the north-eastern limestone region of Vietnam, the Cham Chu (Tuyen Quang Province) and Bac Me (Ha Giang Province) Nature Reserves were conducted in 2018 and 2019. Thirty-five species of small mammals were recorded based both on field observations and on morphological and/or molecular evidence, as follows: one Scandentia species, four Eulipotyphla species, 14 Chiroptera species, and 16 Rodentia species. New records of Aselliscus dongbacanus and Chiromyscus thomasi in north-eastern Vietnam have been confirmed. Interestingly, the mole specimens collected during this study resemble Euroscaptor orlovi morphologically but significantly differ from it genetically. The present study has revealed that Chiroptera (38.9%) and Rodentia (47.2%) are the dominant groups in terms of their species diversity. Yet, the number of bat species is much lower as compared to that revealed by the previous study conducted in the same region (16 vs. 35). Although a couple of abundant species — Aselliscus dongbacanus (40 of 176 specimens) and Hipposideros cf. larvatus (37 of 176 specimens) — have been found during the present survey, other common species, such as Callosciurus inornatus and Rhizomys pruinosus, were very scarce, suggesting the occurrence of a severe anthropogenic pressure on small mammal fauna. More studies to assess a conservation status of and anthropogenic threats to small mammals are needed to protect them from serious population decline in the future.

Thirty-five species of small mammals were recorded based both on field observations and on morphological and/or molecular evidence, as follows: one Scandentia species, four Eulipotyphla species, 14 Chiroptera species, and 16 Rodentia species. New records of Aselliscus dongbacanus and Chiromyscus thomasi in north-eastern Vietnam have been confirmed. Interestingly, the mole specimens collected during this study resemble Euroscaptor orlovi morphologically but significantly differ from it genetically. The present study has revealed that Chiroptera (38.9%) and Rodentia (47.2%) are the dominant groups in terms of their species diversity. Yet, the number of bat species is much lower as compared to that revealed by the previous study conducted in the same region (16 vs. 35). Although a couple of abundant species — Aselliscus dongbacanus (40 of 176 specimens) and Hipposideros cf. larvatus (37 of 176 specimens) — have been found during the present survey, other common species, such as Callosciurus inornatus and Rhizomys pruinosus, were very scarce, suggesting the occurrence of a severe anthropogenic pressure on small mammal fauna. More studies to assess a conservation status of and anthropogenic threats to small mammals are needed to protect them from serious population decline in the future.
