Abstract:

Closely related animal species living in similar conditions can enter into competitive relationships. The study of parasitic worms of animal hosts living in the same habitats is of great interest. We conducted a comparative analysis of the parasitic worms of cohabiting mice Apodemus flavicollis and Apodemus uralensis in the Mordovia Nature Reserve and the National Park “Smolny” (European Russia) in 2018–2022. A total of 1457 individuals of the two mouse species were examined by the complete helminthological necropsy: 635 A. flavicollis and 822 A. uralensis. In total 17 species of parasitic worms were recorded, including five cestodes, four trematodes, and eight nematodes. We found that the species diversity of helminths is higher in A. uralensis. All 17 species of parasites were identified in this rodent. The helminth fauna of A. flavicollis is less diverse and represented by 10 parasite species, also characteristic of A. uralensis, including three tapeworms, two flukes, and five nematodes. Apodemus flavicollis and A. uralensis inhabit similar forest habitats and are characterized by an average degree of similarity in helminth composition. The identified differences in the helminth fauna may be associated with the food preferences of these mouse species and the features of their microhabitats. Infection of the two mice with shared helminth species varied among the protected areas studied. At some sampling sites, the infection of A. flavicollis turned out to be higher, at others – of A. uralensis, which is due to changes in the moisture content of the forest floor and a different number of food items (invertebrates) that are intermediate hosts of helminths. The data obtained confirm the partial overlap of ecological niches of sympatric forest rodents, mainly in the spatial and trophic components.

Abstract:

This article presents the results of a comparative analysis of two physiographic regions of Azerbaijan. 19 species of lagomorphs and rodents are registered in the Samur-Davachi physiographic region. 7 Western Asian species predominate in this area (36.84%): Lepus europaeus, Hystrix indica, Allactaga euphratica, Cricetulus migratorius, Meriones libycus, Microtus sosialis, Sylvaemus witherbyi. 6 (31.58%) species (Glis glis, Dryomys nitedula, Microtus arvalis, Micromys minutus, Apodemus agrarius, Apodemus (Sylvaemus) uralensis) are of European origin, 3 (15.78%) species (Arvicola amphibius,Microtus majori, Mus musculus) are of widely distributed in Palearctic, 1 (5.26%) species (Allactaga elater) is of Turanian origin, 1 (5.26%) species (Rattus norvegicus) is listed as an alien species and 1(5.26%) species (Apodemus(Sylvaemus)ponticus) is Caucasus endemic. Major species are of Western Asian and European origin, and least ones of turanian origin. South Asian species are not found. An analysis carried out in the Zaqatala-Lahyj physiographic region showed that 4 (21.05%) species (Arvicola amphibius, Microtus majori, Mus musculus, Ratus rattus) are widespread in the Palearctic region, 5 (26.31%) species (Lepus europaeus, Hystrix indica, Cricetulus migratorius, Microtus socialis, Sylvaemus witherbyi) are widespread in the Western Asian region, 5 (26.31%) species (Glis glis, Dryomys nitedula, Mus macedonicus, Apodemus (Sylvaemus) uralensis, Microtus arvalis) are of European origin and 5 (26.31%) species (Sciurus anomalus,Microtus dagestanicus,Chionomys gud, Chionomysroberti, Apodemus (Sylvaemus) ponticus) are endemics. No desert species of Turanian origin were noted. In the Zaqatala-Lahyj physical-geographic region, species of European and Western Asian origin are also predominant. A total of 25 rodent species have been registered in these regions. Of the species distributed in the Samur-Davachi and Zaqatala-Lahyj physiographic regions, only 13 (52%) species are found in both physiographic regions. It should be noted that each physiographic region has its own specific species. 6 species (Sciurus anomalus, Microtus dagestanicus, Chionomys gud, Chionomys roberti, Mus macedonicus, Rattus rattus) are found in the Zaqatala-Lahyj physiographic region only, 6 species (Allactaga euphratica, Allactaga elater, Meriones libycus, Apodemus agrarius, Rattus norvegicus, Micromys minutus) are found in the Samur-Davachi physiographic region only.

Abstract:

В статье рассматривается вопрос сопряженности пространственного распределения популяций мелких млекопитающих (лесных мышей и полёвок) и структуры растительного покрова. Исследование проводили в летний период 2023 г. на территории ООПТ «Малиновая гряда» (г. Нижний Новгород) с прилегающей водоохранной зоной реки Оки. Отлов осуществлялся в границах пробных площадей, выбор которых обусловлен различным характером растительного покрова. В липняках доминантным видом являлась рыжая полёвка ( Myodes glareolus ). Одинаковая численность двух видов зверьков - рыжей полёвки и полевой мыши ( Apodemus agrarius ) - отмечена в лиственничнике медуницевом. Выявлено, что более высокая освещённость обуславливает заселение полевой мышью отдельных участков леса и её содоминирование с рыжей полёвкой. Низкая освещённость характерна для вязовника волосисто-осокового, где в представленности грызунов доминировала малая лесная мышь ( A. uralensis ). Для рыжей полёвки и полевой мыши выявлено по одному местообитанию с положительной биотопической приуроченностью, для малой лесной и желтогорлой мыши ( A. flavicollis ) - по два. Приуроченность микроместообитаний рыжей полёвки к растительным ассоциациям, с доминированием сныти обыкновенной ( Aegopodium podagraria ) по результатам анализа избыточности, статистически значима. The article considers the issue of the conjugacy of the spatial distribution of populations of rodents and the structure of vegetation cover. The study was conducted in the summer of 2023 on the territory of the protected area "Malinovaya gryada" (Nizhny Novgorod) with the adjacent water protection zone of the Oka River. The capture was carried out within the boundaries of the sample areas, the choice of which is due to the different nature of the vegetation cover. In the linden forests, the dominant species was the Myodes glareolus . The same number of two species of animals ( Myodes glareolus and Apodemus agrarius ) it is noted in the larch medunitsevy. It was found out that higher illumination causes the Apodemus agrarius to inhabit certain areas of the forest and its sodomination with the Myodes glareolus . Low illumination is typical for the hairy-sedge elm, where the A. uralensis dominated the rodent representation. For the Myodes glareolus and the Apodemus agrarius , one habitat with positive biotopic confinement was identified, for the A. uralensis and A. flavicollis - two each. The association of the Myodes glareolus microhabitats with plant associations, with the dominance of the common vole ( Aegopodium podagraria ), according to the results of the redundancy analysis, is statistically significant.

Abstract:

To know rodent species in an area is important in wildlife management studies, forestry applications, conservation purposes, and public health studies because of some rodent-borne diseases. To determine rodent species and their distribution in Zonguldak was aimed to supply a detailed inventory data and distribution maps for further studies in future. Samples were collected mostly by Sherman traps, and rarely conventional cage-like traps, phototraps, or visually from 33 localities that represent different habitat types, between 2009 and 2016. A total of 427 specimens from 15 species were evaluated. These species are: Sciurus anomalus, Myodes glareolus, Microtus subterraneus, M. levis, Apodemus flavicollis, A. sylvaticus, A. uralensis, A. witherbyi, A. mystacinus, Rattus rattus, R. norvegicus, Mus domesticus, M. macedonicus, Glis glis and Muscardinus avellanarius. Of them S. anomalus, M. levis, A. uralensis, M. macedonicus and M. avellanarius were recorded by primary data for the first time from Zonguldak. According to the results, Sciurus anomalus, Apodemus flavicollis and Glis glis are the most common species by being recorded from 13, 12 and 9 localities, respectively. Among the 33 localities trapped, Kurtköy and Beldibi areas have highest number of rodent species by each having 7 species. Trap Night Index (TNI) was calculated to find the most caught rodent species, the overall trap success for rodents caught and the localities where the majority of rodent samples were caught. TNI was calculated as 21.43 for seven of the localities studied. Skull and pelage morphology (pectoral spot expressions, the posterior end of the palatal bone, pterygoid process, fronto-parietal suture and upper molar crown patterns) were used to identify Apodemus species. Morphological evaluations of Apodemus specimens verified the occurrence of A. sylvaticus in Asiatic Turkey.

Abstract:

Bone remains of amphibians, reptiles and small mammals from unconsolidated deposits of Chesnochnaya Cave (Kushtau, Ishimbaysky district of the Republic of Bashkortostan, Southern Fore-Urals) were studied. Amphibians are represented by Pelobates fuscus, Bufo bufo, Bufotes viridis, Rana arvalis. Emys orbicularis, Anguis fragilis, Natrix tessellata, Vipera berus belong to reptiles. The identified species composition of amphibians and reptiles from the Chesnochnaya Cave locality consists of species characteristic of various biotopes of the Southern Fore-Urals. The Holocene fauna of amphibians and reptiles on the area of Southern Fore-Urals was discovered and studied for the first time. In the small mammal community from the Chesnochnaya Cave locality, the codominants were Myodes ex gr. glareolusrutilus, Chiroptera, and Microtus arvalis; the subdominants were Apodemus flavicollis, Apodemus ex gr. uralensis-agrarius, Sorex sp., Cricetus cricetus, Arvicola amphibious, Eliomys quercinus, Talpa europaea, Lagurus lagurus, Microtus agrestis, Eolagurus luteus and Alexandromys oeconomus; the rare ones were Crocidura sp., Ochotona pusilla, Ellobius talpinus, Craseomys rufocanus and Mustela nivalis. The main group in the community is made up of taxa characteristic of the late Holocene of the Southern Urals and of the modern fauna of small mammals of the Southern Fore-Urals — Sorex sp., Eliomys quercinus, Apodemus ex gr. uralensis-agrarius, Cricetus cricetus, Arvicola amphibious. The community of small mammals is characterized by a significant group of forest and meadow species, meanwhile typical steppe species are also present — Crocidura sp., Ochotona pusilla, Lagurus lagurus, Eolagurus luteus, the bone remains of which could have been redeposited from more ancient Holocene horizons.

Abstract:

AbstractMice of the genus Apodemus are widely distributed across Eurasia. Several species of this genus are hosts of important zoonotic diseases and parasites. The evolutionary history and dispersal routes of these mice remain unclear and the distribution of these species in China was poorly explored in previous studies. We here investigate the divergence times and historical geographical evolution of Apodemus and study the taxonomy of species in China by integrating molecular and morphological data. The crown age of this genus is dated to the Late Miocene, approximately 9.84 Mya. Western and Central Asia were inferred as the most likely ancestral area of this genus. Moreover, we recognize nine living species of Apodemus in China: Apodemus uralensis, A. agrarius, A. chevrieri, A. latronum, A. peninsulae, A. draco, A. ilex, A. semotus and A. nigrus sp. nov., the last from the highlands (elevation > 1984 m) of Fanjing Mountain in Guizhou Province and Jinfo Mountain in Chongqing Province. This new species diverged from A. draco, A. semotus and A. ilex approximately 4.53 Mya. The discovery of A. nigrus highlights the importance of high mountains as refugia and ‘isolated ecological islands’ for temperate species in south-eastern China.

Abstract:

The spatial distribution of Apodemus species (yellow-necked, field, and small forest mice) was studied on the example of the protected area «Oak forest of National Research Lobachevsky State University of Nizhny Novgorod Botanical Garden». Twelve plant associations with non-moral character and representing derivatives of the indigenous type of vegetation were studied. Environmental conditions assessed by the Ellenberg phytoindication method affect the distribution of small mammals in space indirectly. The nature of vegetation cover is more significant. When projective cover increases, the abundance of both small woodland and field mice increases. The strategy of Apodemus agrarius appears to be similar to that of Apodemus uralensis, a species that shows stenobiontic traits in the studied PA. At the same time, insignificant anthropogenic load, a marker of which is the presence of Urtica dioica ruderal species, leads to an increase in the mosaic of vegetation cover, which has a positive effect on the abundance of these small mammal species. A moderate increase in the Berger-Parker dominance index for vegetation cover is positively associated with the confinement of micromammals. In addition, in the conditions of the recreational zone of the upland part of N. Novgorod, Apodemus agrarius prefers areas of old-growth broadleaved forest, not showing the features of anthropophily.

Abstract:

The paper deals with a comparative analysis of the features of the population organization of the Myodes glareolus and the Apodemus uralensis on the territory of the State Nature Reserve Kologrivsky Forest named after M.G. Sinitsyn. This research is a part of a long-term monitoring of the state of populations of dominant species of small mammals on the site of the Kologrivsky Reserve. The paper presents factors of the dynamics of the density of rodent populations, considers trends in the number of individuals of the studied species, their sex and age structure, characteristics of interior and exterior features. The general tendencies and regularities of rodent adaptation to various external environmental factors are revealed. The authors have established a direct statistical dependence of the density of the studied populations on the average air temperature and an inverse dependence on the amount of precipitation. The dependence of exterior and interior features on the gender and age structure, population dynamics and weather conditions is traced. The role of autoregulation of integral population indicators as one of the mechanisms for maintaining its homeostatic state is considered. The revealed patterns allow us to make a forecast of the population dynamics of the Myodes glareolus and the Apodemus uralensis on the territory under consideration. It is possible to use the results of the study as a control example for comparison with other populations of cyclomorphic rodents in ecologically contrasting conditions of forest biocoenoses.

Abstract:

We tested whether the prevalence of ticks can be predicted reliably from a simple epidemiological model that takes into account only mean abundance and its variance. We used data on the abundance and distribution of larvae and nymphs of 2 ixodid ticks parasitic on small mammals (Apodemus agrarius,Apodemus flavicollis,Apodemus uralensis,Clethrionomys glareolusandMicrotus arvalis) in central Europe.Ixodes triangulicepsis active all year round, occurs in the study area in the mountain and sub-mountain habitats only and inhabits mainly host burrows and nests, whereasIxodes ricinusoccurs mainly during the warmer seasons, occupies a large variety of habitats and quests for hosts outside their shelters. InI. ricinus, the models withkvalues calculated from Taylor's power law overestimated prevalences. However, if moment estimates ofkcorrected for host number were used instead, expected prevalences of both larvae and nymphsI. ricinusin either host did not differ significantly from observed prevalences. In contrast, prevalences of larvae and nymphs ofI. triangulicepspredicted by models using parameters of Taylor's power law did not differ significantly from observed prevalences, whereas the models with moment estimates ofkcorrected for host number in some cases under-estimated relatively lower larval prevalences and over-estimated relatively higher larval prevalences, but predicted nymphal prevalences well.

Abstract:

Characters of taxonomy and evolutionary scenario based on genetic differentiation of generic groups of forest and field mice Apodemus s. l. were established by analyzing the variability of the cyt-b (cytochrome-1, cytb) gene. For this purpose, 124 sequences of Apodemus s. l. and other Palaearctic Muridae genera (Mus, Micromys, Rattus) were downloaded from GenBank. The adequacy of the categories of semispecies, allospecies, species, whose genetic differentiation corresponds to GD ranges of 0.03–0.06, 0.06–0.1 and 0.1–0.15, has been proven. Within the genus Sylvaemus the following species are recognised: S. (Sylvaemus) alpicola, S. (S.) arianus (= witherbyi), S. (S.) flavicollis, S. (S.) hyrcanicus, S. (S.) ponticus, S. (S.) (superspecies) sylvaticus, S. (S.) (superspecies) uralensis, S. (Karstomys) epimelas, S. (K.) mystacinus, S. rusiges: within Apodemus: A. agrarius, A. chevrieri, within Alsomys: Al. argenteus, Al. (superspecies) major (= peninsulae), Al. nigrus, Al. semotus, Al. speciosus. Generic taxonomy remains ambiguous, which is caused not only by different scales of differentiation of most species of Western and Eastern Palaearctic lineages, but also by the lack of information on key genus-specific characters: the number of roots on upper molars and number of mammary glands for most East Asian species.

Abstract:

In this study, we investigated the gastrointestinal helminth fauna of small mammals in the highland region of Usholta (Racha, Western Georgia). In total, 19 specimens of small mammals were examined, of which 10 gastrointestinal helminth species were detected. Five out of eight specimens of Apodemus uralensis were infected with three nematode species: Heligmosomoides polygyrus, Syphacia obvelata, and Trichuris muris. Notably, the liver of a single individual of A. uralensis was also infected with cestode—Echinococcus multilocularis, (larvocysts) —a novel host record for this parasite in Georgia. All eight exeminated Microtus daghestanicus specimens were infected with both cestode (Paranoplocephala omphalodes and Rodentolepis asymmetrica) and nematode (Heligmosomum costellatum and Syphacia sp.) parasites. Similarly, all three exeminied specimens of Mustela nivalis were infected with cestodes (Versteria mustelae) and nematodes (Molineus patens, Syphacia sp.). For Syphacia sp., M. nivalis is a new host record in Georgia. Only one specimen of A. uralensis was simultaneously infected by two species of nematodes (Syphacia sp., T. muris) and also a single individual of M. nivalis was infected with three species of helminths (V. mustelae, M. patens, Syphacia sp.). This study provides valuable insights into the helminth diversity and host-parasite relationships in the region, highlighting the importance of continued research on wildlife parasites.

The work presents unpublished data on the diet of this subspecies from several territorial units of eastern and northern Slovakia, obtained from pellets and the nest linings in boxes (1 ,564 pieces). There is less data about prey brought to young in the nest but still not yet consumed (137 pieces). Published data from analysis of the stomachs of dead and shot owls come from the first six decades of the 20th century. Together with existing published data, 2,134 pieces of the diet of S. uralensis from Slovakia are evaluated. They indicate the dominance of non-forest species Microtus arvalis and a more plentiful representation of larger species of prey: Lepus europaeus, Sciurus vulgaris and Corvus sp. In upper Orava the diet of young S. uralensis also consists of frogs Rana temporaria, moles Talpa europaea and mountain species of rodents: Microtus agrestis, M. subterraneus, Sicista betulina and Arvicola amphibius. In data from the mountains of central Slovakia the Clethrionomys glareolus has high abundance, and in eastern Slovakia the Apodemus flavicollis and A. agrarius are more represented, and in the lowlands also the Cricetus cricetus. Upon evaluation ofmaterial from the entire breeding grounds of S. uralensis it can be deduced that the basic diet consist of mammals (88.6%) from the orders Soricomorpha and Rodentia. In the countries of Central Europe the species M. arvalis, M. subterraneus, A. flavicollis and Muscardinus avellanarius are more abundantly represented, and in the Baltic states the species Sorex araneus, M. agrestis, M. oeconomus and M. rossiaemeridionalis. The species S. betulina and A. agrarius occur in the diet of S. uralensis from Central Europe up through the Far East.

Abstract:

The study of the species composition, biological and ecological features of small mammals was carried out for five years (2018–2022) in the surroundings of the village of Rozsohuvata (Kharkiv Oblast, Ukraine). During the study period, nine species of mouse-like rodents and three species of insectivorans were detected. The re-search area is represented by a ravine-beam system, agrocoenoses, field-protecting forest strips, riparian vege-tation around artificial reservoirs and streams, dry meadows, and pastures. Trappings of small mammals were carried out on thirty lines of traps. During the entire period of trapping, the dominant species was Sylvaemus uralensis and in some seasons Sylvaemus sylvaticus dominated. Starting from 2018, the relative abundance increased in autumn, reached a peak in 2020 and declined in the following years. In general, 2019 was the year of maximum abundance and most species were recorded in the summer of this year. The greatest number of species was found in the ecotone between riparian vegetation and field (10 species), as well as in the area of the multi-grass steppe in the beam (8 species). The eurytopic species include Sylvaemus uralensis and Syl-vaemus sylvaticus, whereas the stenotopic species is Mus spicilegus. According to the obtained abundance scores, only one species—Myodes glareolus—occurs randomly, whereas the rare species here are Mus spicile-gus, Sorex minutus, and Crocidura suaveolens. Six species are non-abundant: Apodemus agrarius, Sylvaemus tauricus, Mus musculus, Microtus levis, Cricetulus migratorius, and Sorex araneus. Only Sylvaemus sylvaticus belongs to common species, and only Sylvaemus uralensis is abundant. It should be mentioned that Cri-cetulus migratorius, which usually belongs to the category of random or rare species, turned out to be non-abundant in the study region, and it was recorded regularly in almost half of the studied biotopes. Myodes glareolus, which usually prefers oak forest, was extremely rare. The abundance of Apodemus agrarius, which usually belongs to common species in river valleys, was also low. Sylvaemus showed greater ecological valence, dominated in abundance and inhabited most biotopes, except for Sylvaemus tauricus, which began to occur only in the last two years and mainly in forest strips.

Abstract:

The article is devoted to the ecological and faunal analysis of the family Muridae of Ternopil Region, namely, the study of species composition, relative abundance, landscape distribution, and habitat preferences of the representatives of this group. The species composition of the mammal fauna of all six landscape areas was analysed and the habitat preferences of rodents were determined. The materials were collected during 2017–2020, and 7350 trap-days were processed and 206 specimens of rodents were trapped, representing 7 species. The richest, in terms of genus and species composition, is the tribe Apodemurini, represented by the genera Apodemus (1 species), Micromys (1), and Sylvaemus (3). The tribe Murini is less rich and is represented by two species of two genera, Mus (1) and Rattus (1). The most abundant and widespread species of the first tribe is the yellow-necked wood mouse (Sylvaemus tauricus), the others are common species (Apodemus agrarius, S. uralensis, S. sylvaticus, and Micromys minutus). The second group includes two alien species that have the status of abundant, particularly in synanthropic habitats: the house mouse (Mus musculus) and the brown rat (Rattus norvegicus). The geographical ranges of the identified species are characterised. The described species are common in their natural zones and habitat types. The differentiation of representatives of the genus Sylvaemus (S. tauricus, S. uralensis, and S. sylvaticus) according to their habitat preferences in different types of forest biocenoses was confirmed. The alien species Mus musculus and Rattus norvegicus, preferring urban areas, form exantropic colonies in summer. Ruderal habitats are attractive for Apodemus agrarius and Micromys minutus. The natural habitats of mouse-like rodents in the region are quite heterogeneous, although they are represented by one ecological group, which the authors designate as ‘terrestrial-burrowing’ animals. Distribution maps of each species of the family Muridae in western Podillia are presented. The distribution cadastres were compiled on the basis of spring and summer surveys of typical habitats of mouse-like rodents in six landscape areas of Western Podillia. Only the locations of exantropic settlements in the region were included in the Mus musculus and Rattus norvegicus cadastres.

Abstract:

Впервые изучены эколого-физиологические и видовые особенности системы лей- коцитов крови двух видов цикломорфных грызунов – рыжей полевки Myodes glareolus Schreber, 1780 и малой лесной мыши Apodemus uralensis Pallas, 1811 на сопредельных территориях Коло- гривского и Костромского районов Костромской области. Установлено, что лейкоформулы иссле- дуемых грызунов видоспецифичны и значимо отличаются у особей, обитающих на территории заповедника «Кологривский лес» и на территории Костромского лесничества. Многофакторный дисперсионный анализ выявил существенное влияние на лейкоформулу всех изученных фак- торов: «локация отлова», «видовая принадлежность», «пол», «стадия популяционного цикла» и «год исследования». Относительно высокая степень девиации индекса селезенки у исследуемых видов свидетельствует о неоднородности популяций по данному признаку. При этом достоверной сопряженности риска развития спленомегалии у мышевидных грызунов с особенностями их ре- продуктивной стратегии и восприимчивости к инвазиям не обнаружено. The ecological, physiological and species-specific characteristics of the leukocyte profile of two species of cyclomorphic rodents, the bank vole Myodes glareolus (Schreber, 1780) and the pygmy wood mouse Apodemus uralensis (Pallas, 1811), were studied for the first time in the adjacent territories of the Kologriv and Kostroma districts of the Kostroma Oblast. It was established that the leukocyte profiles of the studied rodents are different in different species and vary significantly among individuals inhabiting the Kologrivsky Forest Reserve and the Kostroma Forestry. Multivariate analysis of variance showed that the white blood cell differential parameters largely correlate with the following factors: “location of capture,” “taxonomic species,” “gender,” “stage of the population cycle,” and “year of study.” The relatively high degree of deviation of the splenic index in the studied species indicates the heterogeneity of populations for this trait. At the same time, no reliable association was found between the risk of developing splenomegaly in mouse-like rodents, and the characteristics of their reproductive strategy and susceptibility to invasions.

Abstract:

The article considers the issues of carriage by small mammals of dangerous zoonotic diseases: leptospirosis, tularemia, hantaviruses. Data on the detection of antigens to pathogens in the districts of the Kaluga region are presented. As you know, small mammals are the main link in maintaining zoonotic natural focal diseases. The larval phases of ixodic ticks, mosquitoes and other parasitic arthropods prefer to feed on the blood of mouse rodents, which contributes to the spread of vector-borne infections and infestations. The following species of mouse rodents are found in the Kaluga Region: small forest mouse (Apodemus uralensis), gray vole, red vole (Myodes glareolus), field mouse (Apodemus agrarius), gray rat (Rattus norvegicus), and house mouse (Mus musculus). In natural biotopes, field species prevail in number: field mouse, gray vole, red vole. In the Kaluga region, antigens for tularemia, hantaviruses, and leptospirosis were found in small mammals in 4.9–9.4% of the studied animals on average per year. Of particular concern are the city of Kaluga, Borovsky, Babyninsky, Yukhnovsky, Ulyanovsk, Medynsky, Maloyaroslavetsky, Meshchovsky, Peremyshlsky, Kozelsky, Dzerzhinsky and Ulyanovsk districts. The data obtained indicate the stationarity of these diseases in the territory of the Kaluga region.

Abstract:

We assessed the sexual size dimorphism (SSD), analyzing standard morphometric traits in juveniles, subadults, and adults, of 14 species of voles, mice, and shrews in Lithuania on the basis of long-term surveys, updating information published 35 years ago and in the context of data from other countries. ANOVA, t-tests, and a 5% threshold were used in the analyses. Male-biased SSD was observed in Apodemus flavicollis and Alexandromys oeconomus, which was subject to Rensch’s rule, and in three other meadow vole species, with the strongest expression in adult individuals. Female-biased SSD was best expressed in Clethrionomys glareolus and was also identified in four mouse species, although patterns were less consistent across age groups. Shrews and the smallest mouse, Apodemus uralensis, exhibited monomorphic traits. The transition of dimorphism during postnatal development was observed in some species. We present an assessment of SSD in Microtus rossiaemeridionalis and Sicista betulina, the less common small mammals not analyzed in publications by other authors, and provide new baseline data for boreal mid-latitude small mammal species as a foundation for future studies on SSD and its adaptive significance under shifting ecological pressures or climate change.

Abstract:

In this study, we investigated the gastrointestinal helminth fauna of small mammals in the highland region of Usholta (Racha, Western Georgia). In total, 19 specimens of small mammals were examined, of which 10 gastrointestinal helminth species were detected. Five out of eight specimens of Apodemus uralensis were infected with three nematode species: Heligmosomoides polygyrus, Syphacia obvelata, and Trichuris muris. Notably, the liver of a single individual of A. uralensis was also infected with cestode—Echinococcus multilocularis, (larvocysts) —a novel host record for this parasite in Georgia. All eight exeminated Microtus daghestanicus specimens were infected with both cestode (Paranoplocephala omphalodes and Rodentolepis asymmetrica) and nematode (Heligmosomum costellatum and Syphacia sp.) parasites. Similarly, all three exeminied specimens of Mustela nivalis were infected with cestodes (Versteria mustelae) and nematodes (Molineus patens, Syphacia sp.). For Syphacia sp., M. nivalis is a new host record in Georgia. Only one specimen of A. uralensis was simultaneously infected by two species of nematodes (Syphacia sp., T. muris) and also a single individual of M. nivalis was infected with three species of helminths (V. mustelae, M. patens, Syphacia sp.). This study provides valuable insights into the helminth diversity and host-parasite relationships in the region, highlighting the importance of continued research on wildlife parasites.

Abstract:

This study reviews the taxonomy of cestodes of the genus Catenotaenia Janicki, 1904 (Cyclophyllidea: Catenotaeniidae) in Eurasia and presents the first molecular phylogenetic hypothesis of Catenotaenia, Skrjabinotaenia Ahumyan, 1946 and Meggittina Lynsdale, 1953, all parasites of rodents. The phylogenetic data are based on sequences of 28S ribosomal RNA. The analysis does not support the proposed subfamilial classification of the Catenotaeniidae into Catenotaeniinae Spasskii, 1949 and Skrjabinotaeniinae Genov & Tenora, 1979. Instead, the main division appears to be between Eurasian species and a basal Nearctic species. The results support the monophyly of the Skrjabinotaeniinae but not that of the Catenotaeniinae or Catenotaenia as traditionally understood. It is suggested that the Old World catenotaeniid cestodes appeared in murid rodents and diverged subsequently as Skrjabinotaenia and Meggittina (Skrjabinotaeniinae) in Africa. According to the molecular phylogeny, Eurasian Catenotaenia codiverged with their hosts, with the exception of Catenotaenia dendritica that originated via a host shift from murid rodents to squirrels. The crown clade of Eurasian Catenotaenia consists only of species found in cricetid rodents and the three terminal species only in the Arvicolinae (voles). Phylogenetic structure within the Eurasian Catenotaenia clade suggests seven distinct lineages, three of which are described as new: C. apodemi n. sp. from Apodemus peninsulae (type host) from the Republic of Buryatia and from Apodemus uralensis from the Lower Tunguska River, North-Central Siberia (Russian Federation); C. cricetuli n. sp. from Cricetulus barabensis from the Republic of Buryatia and C. microti n. sp. from Microtus socialis from Kazakhstan. A new genus (Catenotaenioides n. g.) is proposed for C. kirgizica Tokobaev, 1959, a basal species within the Old World clade. Of the various morphological features, proglottid form (short acraspedote proglottids widest at middle vs. elongated craspedote proglottids widest posteriorly) is consistent with the phylogenetic pattern exhibited by catenotaeniid cestodes.

Abstract:

Abstract The extant species of the genus Apodemus represent the most common small mammals of Central Europe. Unfortunately, their phylogenetic past is only poorly known. With the aid of detailed biometric analyses we tried to identify the first appearance of the phenotypic patterns characterizing the extant populations. We examined dental material of Apodemus from 53 community samples from the territory of the Czech Republic and Slovakia dated from the early Villanyian (MN 16/17) to the late Middle Pleistocene (Q 3) with particular respect to their correspondence with the morphometric characteristics of the extant species. While the Toringian (Q 3) interglacial samples invariably include forms identical with the extant taxa A. flavicollis, A. sylvaticus and supposedly A. uralensis (including the items corresponding to A. maastrichtiensis), the samples of Early Pleistocene age (MN 17 – Q 2) exhibited clear differences in the variation pattern which results in questioning the possibility of their co-identification with the respective extant species. In most instances they varied within the limits in resembling A. sylvaticus but exceeded its variation ranges in some non-metric characters. Regarding serious doubts on real taxonomic status of other named fossil species we propose to denote these Plio-Pleistocene sylvaticus-like phenotypes provisionally with the prior name A. atavus Heller, 1936.

Abstract:

New data were obtained on the implementation of the Alaria alata life cycle in the conditions of the Central Black-Soil Region. Based on the materials of our research, paratenic hosts of A. alata were identified: Natrix natrix, Vipera berus, Neovison vison, Myodes glareolus. Alaria mesocercariae were observed in all the studied Natrix natrix (27 specimens) and Vipera berus (7 specimens) with the extensiveness of infestation (EI) of 100%. Intensity of infestation (II) averaged 12.0 specimens in N. natrix (2–18 specimens) and 261.3 specimens (12–627 specimens) in V. berus. Alaria mesocercariae were found in the Neovison vison with localization mainly in the esophagus, subcutaneous tissue, striated muscles, and serous integuments. The maximum number of mesocercariae was found in the esophagus – 50 specimens. The M. glareolus was registered as a paratenic host of A. alata with localization of mesocercariae in the M. glareolus in the esophagus. Taking into account the earlier helminthofaunistic materials on the study of the life cycle of A. alata conducted in the Voronezh Region and adjacent areas, other species of mammals were also registered as paratenic hosts. Mesocercariae have been recorded in Sus scrofa, mouse-like rodents: M. glareolus and Microtus arvalis, mice: Apodemus uralensis, Apodemus flavicollis and A. agrarius, Dryomys nitedula and Castor fiber.

Abstract:

This paper deals with the problem of the connection between small mammals spatial distribution and the vegetation cover. The study was carried out during the summer period of 2018 and 2019 in the landscape protected area Oakwood of the NNSU Botanical Garden in the province of Nizhny Novgorod. Three relevs were set up in various plant associations: Ulmetum pulmonarioso-asaroso-aegopodiosum, Acereto-Tilietum pulmonarioso-impatienosum (noli-tangerae), Querceto-Acereto-Tilietum asareto-aegopodiosum. A standard geobotanical description was carried out according to the generally accepted method using a series of Raunkier sites registration. Microtine rodents were trapped by standart traps and live traps. The caught animals turned out to belong to 2 genera and 3 species: the bank vole Myodes glareolus Schreber, the pygmy wood mouse Apodemus uralensis Pallas, and the field mouse Apodemus agrarius Pallas. The low population size of animals, as well as the fact that Apodemus agrarius is a co-dominant, may indirectly indicate the anthropogenic pressure in the investigated oak groves. Ecological plasticity of the species Myodes glareolus has been confirmed. Bank voles inhabit micro-habitats with the average data of illumination as well as shaded ones. In general, the vegetation projective cover and the presence of Norway maple undergrowth are crucial for the microtine rodents spatial distribution. Small mammals choose sites with a minimum number of Acer platanoides undergrowth, and gravitate to places where the projective cover of grass has moderate rates (from 35 to 50%). The Principal Component Analysis (PCA) using a vegetation cover species spectrum showed the presence of a significant factor for microtine rodents, which is associated with nitrophilous species (common nettle and touch-me-not balsam). The presence of those plants may indicate a significant anthropogenic pressure on the vegetation cover. In addition, it is important that plants belong to a particular eco-coenotic group. The species Myodes glareolus and Apodemus agrarius differ on the nemoral factor, and their ecological niches do not overlap.

Abstract:

The National Park “Smolny” is a large forest area, located in the center of European Russia. The helminth fauna of myomorph rodents was studied for the first time within the National Park in 2018–2020. Rodents were examined by the method of complete helminthological dissection. A total of 30 species of parasites were recorded in 11 rodent species: 6 trematodes, 11 cestodes and 13 nematodes. The trematode Plagiorchis maculosus (Rudolphi, 1802) was found in Clethrionomys glareolus (Schreber, 1780) from the Russian fauna for the first time. Clethrionomys glareolus and Microtus arvalis (Pallas, 1779) are new hosts for P. maculosus and metacestode Versteria mustelae (Gmelin, 1790), respectively. The most widespread and eurybiont rodent species have the most diverse and rich helminth fauna, such as C/ glareolus (14 species), Apodemus agrarius (Pallas, 1771) (12) and Sylvaemus uralensis (Pallas, 1811) (10). The helminth fauna is less diverse in Sylvaemus flavicollis (Melchior, 1834), M. arvalis (7 species each), Microtus agrestis (Linnaeus, 1761) (5), Microtus subterraneus (de Selys-Longchamps, 1836) (3), Sicista betulina (Pallas, 1779) (2) and Arvicola amphibius (Linnaeus, 1758) (1). Comparative analysis the helminth fauna of small rodents from the National Park “Smolny” with micromammals from other regions of European Russia revealed that the high similarity with other areas reaches the helminth fauna of M. subterraneus, S. flavicollis, S. uralensis, S. betulina, A. amphibius and M. agrestis.

Abstract:

Abstract Accumulation of heavy metals (Cu, Zn, Cd) in hemopoietic-competent organs of ecologically contrast species of small mammals (Clethrionomys glareolus, Sorex araneus, Apodemus uralensis) from natural populations of the Middle and South Urals were considered. The content of exogenous and essential trace elements in animal tissues (a liver, kidney, a spleen) was determined by atomic absorption spectroscopy. It has been shown that bioaccumulation of heavy metals in organs of insectivores significantly differs from it of bank voles and wood mice. The smallest total content of heavy metals is shown in wood mice in technogenic territories of the Middle Urals. The submitted data demonstrate the competitive mechanism of the Cu, Zn, Cd. The increased concentrations of endogenous trace elements (copper, zinc) in relation to a toxicant (cadmium), other things being equal, reduce cadmium accumulation level in the tissues Sorex araneus.

Abstract:

ABSTRACT In May 1999, field surveys of Lyme disease spirochetes were conducted around the Tianshan Mountains in Xinjiang Uygur Autonomous Region in northwestern People's Republic of China. Ixodes persulcatus ticks were obtained in a Tianchi Lake valley with primary forest, while the tick fauna was poor in the semidesert or at higher altitudes in this region. Species identities were confirmed by molecular analysis in which an internal transcribed spacer sequence was used. Of 55 adult ticks, 22 (40%) were positive for spirochetes as determined by Barbour-Stoenner-Kelly culture passages. In addition, some rodents, including Apodemus uralensis (5 of 14 animals) and Cricetulus longicaudatus (the only animal examined), and some immature stages of I. persulcatus (4 of 11 ticks) that had fed on A. uralensis were positive for spirochetes. Based on 5S-23S rRNA intergenic spacer restriction fragment length polymorphism analysis and reactivity with monoclonal antibodies, 35 cultures (including double isolation cultures) were identified as Borrelia garinii (20 isolates, including 9 Eurasian pattern B isolates and 11 Asian pattern C isolates),Borrelia afzelii (10 pattern D isolates), and mixed cultures (5 cultures, including isolates that produced B. garinii patterns B and C plus B. afzelii pattern D). These findings revealed that Lyme disease pathogens are distributed in the mountainous areas in northwestern China even though it is an arid region, and they also confirmed the specific relationship betweenI. persulcatus and genetic patterns ofBorrelia spp. on the Asian continent.

Abstract:

The bone remains of amphibians, reptiles and small mammals from the loose sediments of the entrance grotto of the Grebnevaya cave (the middle reaches of the Yuryuzan River, Southern Urals) were studied. Amphibians are represented by Bufo sp., Pelophylax ridibundus and Rana cf. temporaria. Reptiles — Anguis fragilis, Lacerta cf. agilis, Zootoca vivipara, Coronella austriaca, Natrix sp., Vipera berus. The identified species composition of amphibians and reptiles from the locality consists of species characteristic of various biotopes of the mountainous part of the Southern Urals from the early Holocene to the present. In the earlier deposits of the cave (layer 3), remains of Microtus (Stenocranius) gregalis, Alexandromys oeconomus, Arvicola amphibius predominate; single remains of Allactaga major and Dicrostonyx torquatus were found. The second layer is dominated by remains of Arvicola amphibius, Microtus arvalis and Alexandromys oeconomus. Ochotona pusilla, Cricetulus migratorius, Lagurus lagurus, Microtus (Stenocranius) gregalis and a few Sorex sp., Apodemus ex gr. uralensis-agrarius, Cricetus cricetus, Myodes ex gr. glareolus–rutilus. The youngest layer 1 is dominated by remains of Microtus arvalis, Sorex sp., Myodes ex gr. glareolus–rutilus and Arvicola amphibius. Pteromys volans, Sciurus vulgaris, Apodemus flavicollis, Ochotona pusilla, Cricetulus migratorius, Allocricetulus eversmanni, Lagurus lagurus and Microtus (Stenocranius) gregalis were identified. A change in the ecological groups of small mammals is observed in the locality. In layer 3, the proportion of forest and meadow species is small, and the proportion of steppe species is significant, which is typical for the middle and early Holocene of the mountainous part of the Southern Urals. In layer 3, remains of lemmings were found, a tundra species characteristic of the early Holocene. The first layer is characterized by a significant proportion of forest and meadow species, but typical steppe species are also present. The accumulation of bone remains of small mammals in the Grebnevaya Cave location probably occurred at the end of the early and middle Holocene. The near-surface deposits of the first layer are enriched with species more characteristic of the late Holocene and modern times. Изучены костные остатки земноводных, пресмыкающихся и мелких млекопитающих из рыхлых отложений привходового грота пещеры Гребневая (среднее течение р. Юрюзань, Южный Урал). Земноводные представлены Bufo sp., Pelophylax ridibundus и Rana cf. temporaria. Пресмыкающиеся — Anguis fragilis, Lacerta cf. agilis, Zootoca vivipara, Coronella austriaca, Natrix sp., Vipera berus. Выявленный видовой состав земноводных и пресмыкающихся из местонахождения состоит из видов, характерных различным биотопам горной части Южного Урала с раннего голоцена и до современности. В более ранних отложениях пещеры (слой 3) преобладают остатки Microtus (Stenocranius) gregalis, Alexandromys oeconomus, Arvicola amphibius, обнаружены единичные остатки Allactaga major и Dicrostonyx torquatus. Во втором слое преобладают остатки Arvicola amphibius, Microtus arvalis и Alexandromys oeconomus. Определены Ochotona pusilla, Cricetulus migratorius, Lagurus lagurus, Microtus (Stenocranius) gregalis и немногочисленные Sorex sp., Apodemus ex gr. uralensis-agrarius, Cricetus cricetus, Myodes ex gr. glareolus-rutilus. В наиболее молодом слое 1 преобладают остатки Microtus arvalis, Sorex sp., Myodes ex gr. glareolus–rutilus и Arvicola amphibius. Определены Pteromys volans, Sciurus vulgaris, Apodemus flavicollis, Ochotona pusilla, Cricetulus migratorius, Allocricetulus eversmanni, Lagurus lagurus и Microtus (Stenocranius) gregalis. В местонахождении наблюдается смена экологических групп мелких млекопитающих. В слое 3 доля лесных и луговых видов невелика, а доля степных видов значительна, что характерно для среднего и раннего голоцена горной части Южного Урала. В слое 3 обнаружены остатки лемминга — тундрового вида, характерного для раннего голоцена. Первый слой характеризуется значительной долей лесных и луговых видов, но присутствуют и типично степные виды. Накопление костных остатков мелких млекопитающих в местонахождении пещера Гребневая происходило, вероятно, в конце раннего и в среднем голоцене. Приповерхностные отложения первого слоя обогащены видами более характерными для позднего голоцена и современности.

Abstract:

Relationships between members of the parasitic system formed by the taiga tick Ixodes persulcatus (Schulze, 1930) at the preimaginal developmental stages, Borrelia garinii and small mammals were studied. Transovarial transmission of B. garinii in the taiga tick was not found. In natural biotopes of northwestern Russia, small mammals that were hosts of the preimaginal stages of Ixodes persulcatus included Myodes glareolus (Schreber, 1780) (52–53%), Sorex araneus Linnaeus, 1758 (33–34%), and Apodemus uralensis (Pallas, 1811) (14%). Larvae and nymphs were most numerous on hosts at the beginning of the season, in May and June. Subsequently, their number decreased by 5–10 times and slightly increased in September. In populations, up to 31.9% of M. glareolus individuals and 20.5% of A. uralensis individuals were infected with B. garinii. The aggregated type of distribution of taiga tick larvae and nymphs on hosts has been revealed. Infection of the main part of hungry larvae and nymphs occurred at the beginning of the activity season after wintering when feeding on overwintered infected hosts. This period is the key in circulation (exchange between vectors and reservoir hosts) and the preservation of B. garinii in the natural focus of borreliosis in northwestern Russia. Vertical transmission of B. garinii is possible from larvae and nymphs fed at the beginning of the season to nymphs and adult ticks that had molted in August-September, respectively. Horizontal transmission of the pathogen from small mammals, especially the bank vole, to larvae and nymphs, and vice versa, ensures the circulation and persistence of B. garinii in natural foci. The question of the preservation of the pathogen in overwintering preimaginal stages of ticks requires further research.

Abstract:

A phenetic analysis of non-metric cranial traits of two genetically identified cryptic species of the genus Apodemus in different ecological conditions of the North Caucasus was carried out. The maximum distance obtained between cryptic species did not exceed the level of subspecies differences. The phenetic distance between A. uralensis and A. flavicollis, which inhabit symbiotopically and sympatrically in the Western Caucasus, is almost 2 times lower. The smaller value of phenetic differences is probably related to the habitat of both species in similar land-scapebiotopic and climatic conditions, which contributes to the development of phenotypic similarity. In general, the obtained results indicate weak morphological differentiation of the studied species according to the studied phenetic characters (cranial foramen), although according to the results of molecular genetic analysis of the cyt b gene site, the genetic distance between the studied taxa is 10% and corresponds to the level of interspecific differences. Based on the above, reliable diagnosis of the studied species in the Caucasus is possible only by molecular genetic methods.

Abstract:

The genetic and morphological variability of the southern form of the European chromosomal race of the small wood mouse Apodemus (Sylvaemus) uralensis (Pallas, 1811) in the North Caucasus was studied. The results of the sequence analysis of the cytochrome b gene fragment from 9 geographical samples from the western, central and eastern parts of the North Caucasus indicate a low degree of their genetic isolation with a relatively high diversity of haplotypes. Analysis of morphological variability revealed high variety: three morphological groups were identified. Representatives of all three or two groups were found in the same geographical samples, but their distribution did not conform to the hypothesis of random occurrence. Based on indirect evidence, hypotheses about possible causes of the observed features of regional small forest mouse biodiversity are formulated, which require verification in the course of future studies. In particular, we hypothesised that in the Late Pleistocene (130–11.7 thousand cal yr BP) there were several isolated populations in the region that could have been sources of species diversity in the Holocene.
