Since 1957, zoologists of the Kharkiv Sanitary and Epidemiological Station have been conducting annual monitoring of small mammals in Kharkiv Oblast. To assess the current state of populations of mouse-like rodents and shrews, we analysed a dataset for the period from 2000 to 2018. The small mammal fauna was studied at 117 sites in 27 districts (raions) of Kharkiv Oblast. Various types of oak forests, dry and floodplain meadows, riparian vegetation, steppe areas, forest stripes, gardens, fields, and haystacks were examined. Four species of insectivores and 16 species of mouse-like rodents were identified. The dominant and widespread species in the region are Sylvaemus uralensis, Apodemus agrarius, Sorex araneus, Microtus levis, Myodes glareolus, and Sylvaemus tauricus. Some species are less common and in some areas of the region have not yet been identified, including Sorex minutus, Sylvaemus sylvaticus, Crocidura suaveolens, Micromys minutus, Cricetulus migratorius, and Microtus oeconomus. The least common species with single records include Neomys fodiens, Mus spicilegus, Lagurus lagurus, Terricola subterraneus, Dryomys nitedula, and Arvicola amphibius. Indigenous species of the region include seven species, another seven species are those that increased their number and range, three species have recently appeared in the region due to dispersal from adjacent territories, while, on the contrary, the abundance and range of three species have declines. Microtus oeconomus is characterised by a current southward range expansion. Myodes glareolus, which was mentioned in the last century north of our region, is now widely distributed throughout the region and further south. Lagurus lagurus is an invasive species with periodic population outbreaks in the region and currently is rarely recorded.

Abstract We studied species composition of assemblages of small mammals (rodents and shrews) inhabiting Polish 25 ombrotrophic mires and quaking bogs in several regions in order to reveal characteristic features of their quantitative structure and compare them between regions, internal zones of the bog habitats, and different levels of anthropogenic degradation. We reviewed also all published results of small-mammal trapping in such habitats. Mammals were captured in pitfalls, snap traps and live traps on 12 bogs of the Pomerania region, 4 bogs of the Orawa-Nowy Targ Basin (Kotlina Orawsko-Nowotarska), 3 bogs in the Świętokrzyskie Mts, and 6 bogs in Wielkopolska and the Lubusz Land. Additionally, we included materials collected from Barber traps (pitfalls) used during studies of epigeic invertebrates on 4 bogs. In total, 598 individuals of 12 species were collected. The number of pitfall captures per 100 trapnights was very low (7.0-7.8), suggesting low population density. Shrews predominated among mammals captured in pitfalls, and the assemblage structure appeared to be similar to impoverished forest fauna, slightly enriched with ubiquitous species from meadows and agroecosystems, with a very small percentage of typical wetland species (Neomys fodiens, Neomys anomalus, Microtus oeconomus). Rodents (mostly Myodes glareolus) predominated only in samples obtained by live and snap traps. Pygmy shrew Sorex minutus was the most numerous species at most sites, sometimes being the only small mammal in that habitat, especially in well-preserved, treeless parts of bogs, dominated by Sphagnum peatmoss. The dominance and high constancy of S. minutus appear to be a characteristic feature of small-mammal assemblages inhabiting ombrotrophic mires, at least in some regions of Central and Western Europe. Enrichment of the fauna with other species might be related to either improved trophic conditions (by contact with mineralized ground waters) or habitat degradation (by peat mining, drainage, and subsequent secondary succession).

ABSTRACT The fundamental charge of conservation biology is to preserve biological diversity. Yet, efforts to accomplish this goal have focused too narrowly on reversing the slide toward extinction in already threatened or endangered species. In this review, we argue that conservation biologists and fisheries managers should broaden their vision to include efforts to preserve the ecological and evolutionary processes that ultimately give rise to new biodiversity. Our view is based upon the simple observation that biological diversity is a function of both the rate at which new taxa originate as well as the rate at which established taxa are lost to extinction. Efforts to stem extinction that fail to maintain the ecological and evolutionary processes of speciation are ultimately unsustainable. We suggest that common, widespread species are particularly important to the origin of new diversity and argue that conservation biologists should pay particular attention to the evolution of diversity within such species. We illustrate several key points to this argument using the desert minnow, Utah chub <em>Gila atraria</em>, as a model system. In particular, we show that conservation efforts in common species must focus on clearly delineating conservation unit boundaries and that particular care should be paid to unique ecological and evolutionary diversity within such species.We also show the importance of understanding and conserving the range of ecological and evolutionary interactions that are common hallmarks of abundant and widespread taxa.We conclude our review by suggesting several specific areas of future research in Utah chub that would help more clearly define conservation and management priorities in this species.

Negative Impacts

Because biological invasions can cause many negative impacts, accurate predictions are necessary for implementing effective restrictions aimed at specific high-risk taxa. The pet trade in recent years became the most important pathway for the introduction of non-indigenous species of reptiles worldwide. Therefore, we decided to determine the most common species of lizards, snakes, and crocodiles traded as pets on the basis of market surveys in the Czech Republic, which is an export hub for ornamental animals in the European Union (EU). Subsequently, the establishment and invasion potential for the entire EU was determined for 308 species using proven risk assessment models (RAM, AS-ISK). Species with high establishment potential (determined by RAM) and at the same time with high potential to significantly harm native ecosystems (determined by AS-ISK) included the snakes Thamnophis sirtalis (Colubridae), Morelia spilota (Pythonidae) and also the lizards Tiliqua scincoides (Scincidae) and Intellagama lesueurii (Agamidae).

Abstract One of the less studied positive interactions among organisms is facilitation. Facilitation may have significant impact on diversity of species especially in low productive environments. We studied the effects of well-known facilitator and ecosystem engineer, the North American beaver (Castor canadensis), on small mammal assemblages in the boreal zone. The small mammals, namely voles, mice, and shrews, were trapped over 2 years in ten beaver-modified habitats and in ten control sites. Contrary to our expectations, we did not observe any differences between species or individual numbers between beaver-modified and control sites. However, there were differences in species composition between sites; grass-eating field voles (Microtus agrestis) and invertebrate-eating shrews (Sorex araneus, Neomys fodiens) tended to be more common in beaver sites while forest-dwelling wood lemmings (Myopus schisticolor) and yellow-necked mice (Apodemus flavicollis) were only captured in control sites. The most common species in both habitats was the bank vole (Myodes glareolus), which is a generalist in its habitat requirements. The bank vole’s population structures were similar between the two habitat types. The actions of beavers in water bodies within boreal forests seem to have no effect on the small mammal diversity and their numbers at the regional scale but may have positive effect on them at the larger landscape level as beavers are increasing the overall habitat diversity in the landscape.

Of the five species of helminths of the British muskrat (Ondatra zibethica L.), two (Notocotylus quinqueserialis and Hymenolepis evaginata) have been introduced with the animal. The three other species of helminths (Capillaria hepatica, Taenia taeniaeformis larva and T. tenuicollis larva) have probably been largely re-acquired from the local fauna. All of the three common species of ectoparasites [Laelaps multispinosus (Tetragonyssus spiniger), Listrophorus validus and Dermacarus n.sp.] occur in North America. Three other species (Tyroglyphus sp., Myobia n.sp., Polyplax sp.) have occurred as single individuals, the last species having probably been acquired from the water vole. Introduction into Britain has greatly depleted the original helminth fauna as regards number of species and individuals; but not so with the ectoparasites. Lists of the parasites hitherto recorded from the muskrat are given and those found in brown rats (Rattus norvegicus Erx.) and water voles (Arvicola amphibius amphibius L.).

AbstractThe study is focused on analyses of the impact of urbanized environment on the occurrence and structure of small mammals that are important with regard to transmission of diseases to man and domestic animals. The city of Nitra (Slovakia) was chosen as a model area, where an urban - rural gradient was determined. It was categorized into three zones, depending on the distance from the city centre. Small mammals were examined by a comprehensive annual research during the seasons. Overall, 12 species of small mammals were found, Microtus arvalis (29.6%), Apodemus sylvaticus (23.1%), Apodemus flavicollis (20.6%) were eudominant. The communities of small mammals showed an increase in species diversity and richness from the suburban to the peripheral zone, and a decrease of diversity and richness with increasing urban conditions from the peripheral to the pericentral zone. The identified species of small mammals were categorized according to their dependence on urban environment as exoanthropic species, avoiding the presence of man and his habitations (A. sylvaticus, A. flavicollis, and Clethrionomys glareolus); hemisynantropic species, which thrive on the edges of towns, with greater or lesser affinity to humans (M. arvalis, Apodemus uralensis, Sorex araneus, Sorex minutus, Mus spicilegus, and Microtus subterraneus); and synanthropic species, tied to human dwellings, very dependent on human resources (Crocidura suaveolens).

And Function

Common species shape the world around us, and changes in their commonness signify large-scale shifts in ecosystem structure and function. However, our understanding of long-term ecosystem response to environmental forcing in the deep past is centred on species richness, neglecting the disproportional impact of common species. Here, we use common and widespread species of planktonic foraminifera in deep-sea sediments to track changes in observed global occupancy (proportion of sampled sites at which a species is present and observed) through the turbulent climatic history of the last 65 Myr. Our approach is sensitive to relative changes in global abundance of the species set and robust to factors that bias richness estimators. Using three independent methods for detecting causality, we show that the observed global occupancy of planktonic foraminifera has been dynamically coupled to past oceanographic changes captured in deep-ocean temperature reconstructions. The causal inference does not imply a direct mechanism, but is consistent with an indirect, time-delayed causal linkage. Given the strong quantitative evidence that a dynamical coupling exists, we hypothesize that mixotrophy (symbiont hosting) may be an ecological factor linking the global abundance of planktonic foraminifera to long-term climate changes via the relative extent of oligotrophic oceans.

Common species shape the world around us, and changes in their commonness signify large-scale shifts in ecosystem structure and function. Dominant taxa drive productivity and biogeochemical cycling, in direct interaction with abiotic components of the Earth system. However, our understanding of the dynamic response of ecosystems to global environmental changes in the past is limited by our ability to robustly estimate fossil taxonomic richness, and by our neglect of the importance of common species. To rectify this, we use observations of the most common and widespread species to track global changes in their distribution in the deep geological past. Our simple approach is robust to factors that bias richness estimators, including widely used sampling-standardization methods, which we show are highly sensitive to variability in the species-abundance distribution. Causal analyses of common species frequency in the deep-sea sedimentary record detect a lagged response in the ecological prominence of planktonic foraminifera to oceanographic changes captured by deep-ocean temperature records over the last 65 million years, encompassing one of Earth's major climate transitions. Our results demonstrate that common species can act as tracers of a past global ecosystem and its response to physical changes in Earth's dynamic history.

The paper presents distribution of the European water vole Arvicola amphibius (Linnaeus, 1758) in Mazowsze and southern Podlasie in areas situated within a 120-kilometer radius from Warsaw. Data published so far and unpublished results from analyses of the diet of three common species of owls were set up. The rodent is rare in the study area, especially when compared with southern, western and far northern Poland. Its largest population lives in Kampinos Forest, from where many localities are known. In other parts of the study area it is present locally. Only 14 localities were known outside Kampinos Forest in the years 2000–2017. It is even absent from large areas rich in various water bodies like e.g. Mazowiecki and Chojnowski Landscape Parks or Bolimowska Forest. Rarity of the European water vole was confirmed by 235 large samples of owls’ food (at least 100 of vertebrate prey in each) equally distributed across Mazowsze and southern Podlasie, in which this species was not found.

In Europe, two species of hantaviruses, Puumala orthohantavirus (PUUV) and Dobrava orthohantavirus (DOBV), cause hemorrhagic fever with renal syndrome in humans. The rodent reservoirs for these viruses are common throughout Ukraine, and hence, the goal of this study was to identify the species and strains of hantaviruses circulating in this region. We conducted surveillance of small rodent populations in a rural region in northwestern Ukraine approximately 30 km from Poland. From the 424 small mammals captured, we identified nine species, of which the most abundant were Myodes glareolus, the bank vole (45%); Apodemus flavicollis, the yellow-necked mouse (29%); and Apodemus agrarius, the striped field mouse (14.6%) Using an indirect immunofluorescence assay, 15.7%, 20.5%, and 33.9% of the sera from M. glareolus, A. glareolus, and A. flavicollis were positive for hantaviral antibodies, respectively. Additionally, we detected antibodies to the hantaviral antigen in one Microtus arvalis, one Mus musculus, and one Sorex minutus. We screened the lung tissue for hantaviral RNA using next-generation sequencing and identified PUUV sequences in 25 small mammals, including 23 M. glareolus, 1 M. musculus, and 1 A. flavicollis, but we were unable to detect DOBV sequences in any of our A. agrarius specimens. The percent identity matrix and Bayesian phylogenetic analyses of the S-segment of PUUV from 14 M. glareolus lungs suggest the highest similarity (92–95% nucleotide or 99–100% amino acid) with the Latvian lineage. This new genetic information will contribute to future molecular surveillance of human cases in Ukraine.
