We investigated the composition of small mammals at nine locations in the southwestern suburban zone of Warsaw (central Poland) through the analysis of the pellets of the Tawny owl Strix aluco. In total, we recorded 611 individuals of 15 species of small mammal communities in the diet. Rodents constituted the most numerous mammalian order. Among the most abundant prey we recorded were Myodes glareolus (63 individuals = 10.3% of all mammals), Apodemus agrarius (56 individuals = 9.2%) (173), Apodemus flavicollis (54 individuals = 8.8%), Mus musculus (48 individuals = 7.9%) and Microtus arvalis (44 individuals = 7.2%). We recorded also some species rarely captured by the tawny owl: Nyctalus noctula and Mustela nivalis. Species composition of small mammals of the study area resembled city parks, with several species typical for anthropogenic landscape.

The diet of three owl species was analysed in 32 sites localised in the Masovian Landscape Park and its outskirts to determine the structure of small mammal communities. Study was done in the years 1993–2016, 5,728 vertebrate prey (including 4,001 mammals) were collected. Five species of soricomorphs, six bats, 14 rodents and one species of Carnivora were found. Among mammals, Myodes glareolus had the greatest share in the diet of Strix aluco. Tyto alba most frequently caught Microtus arvalis and Sorex araneus, while Asio otus – M. arvalis and M. oeconomus. Those prey, together with Apodemus flavicollis and A. agrarius, dominated in small mammal communities. One site of Crocidura leucodon was found on the western edge of its range in Poland. The share of bats in the diet of S. aluco was small (0.5% of mammals), Plecotus auritus was most frequent. Muscardinus avellanarius was found in forests of the southern part of the Masovian Landscape Park. It was relatively often caught by S. aluco in favourable habitats. Shares of M. oeconomus, M. agrestis and M. avellanarius in the diet of owls were significantly higher in southern part of the study area remote from Warsaw.

Changes of the moisture regime and its influence on the dominance of selected species of small mammal communities were studied in floodplain forests in southern Moravia (river Dyje). In period of typical floodplain regime characterized by groundwater table fluctuation (1968–1972, with high groundwater table level or floods in spring) dominance of Apodemus flavicollis (Mel.) was 42%, Myodes glareolus (Schreb.) 33% and Sorex araneus L. 15% of the total small mammal communities. In period 1982–1987 after cessation of floods by river regulation, rapid groundwater drop and changes in the herb layer, the dominance of Apodemus flavicollis and Myodes glareolus increased. Also the dominance of Apodemus sylvaticus (L.) increased, but that of Sorex araneus collapsed. Further revitalization measures were applied by systems of channels supplying the water to root system of forest trees but not to the herb layer. In 2002–2006 decreasing moisture condition further influenced the dominance of Apodemus flavicollis reaching mean dominance 62%, Myodes glareolus dominance decreased to 20% and that of Sorex araneus remain to be low. All estimated changes were correlated with moisture regime changes and were significant. Thus the changes in the forest moisture regime significantly affect the community of small terrestrial mammals.

Abstract Purpose Bacteria of the genus Bartonella are obligate parasites of vertebrates. Their distribution range covers almost the entire world, from the Americas to Europe and Asia. Many Bartonella species use rodents as reservoirs, and while much is known about Bartonella infection of rodents in central Europe, its extent is poorly understood in Eastern Europe. Methods The present study examines five rodent species (Apodemus flavicollis, Myodes glareolus, Microtus arvalis, Apodemus agrarius, Apodemus sylvaticus) in the Chernobyl Exclusion Zone in Ukraine. Total of 36 small mammals were captured in September 2017. Results The overall prevalence of Bartonella spp. was 38.9% (14/36) in rodents. Obtained four sequences from Apodemus flavicollis, were identical to Bartonella grahamii and B. taylorii. Conclusion This is the first report to confirm the presence of Bartonella spp. in rodents in the Chernobyl Exclusion Zone, Ukraine by molecular methods. The sequences show similarity to Bartonella strains occurring in Europe.

Changes in small mammal communities following logging were monitored in clear-cut and strip-cut upland black spruce (Picea mariana) stands and in selectively cut mixed wood stands in north-central Ontario. Clear-cutting and subsequent scarification essentially eliminated the vegetative cover. Much of the ground cover recovered within 5 years and shrubs within 12 years, but mosses and lichens took much longer. The small mammal community in both clear-cut and strip-cut stands changed over the first three years after logging from one dominated by southern red-backed voles (Clethrionomys gapperi) to one dominated by deer mice (Peromyscus maniculatus) and then remained relatively stable for up to 13 years after harvest. That shift was not apparent in selectively cut mixed wood stands where the composition of the small mammal community was similar between uncut stands and stands 4–23 years after harvest. There was relatively little change in total numbers of small mammals after logging. In general, the diversity and evenness of small mammals increased or remained stable in the first 1–3 years following harvest, decreased on older (3–16 years) cuts, and then increased to values similar to those in uncut stands on the oldest (19–23 years) cuts.

Francisella tularensisis uzročnik je zoonoze tularemije, koja ima široki raspon domaćina, uključujući člankonošce, sisavce i ptice. Dvije podvrste F. tularensis, subsp. tularensis (Tip A) i subsp. holartica (Tip B), opisane su kao najčešći uzročnici bolesti u ljudi (Kingry and Petersen, 2014; Kuehn et al., 2013). Tip A i Tip B razlikuju se po svojim biokemijskim značajkama, patogenosti, ekologiji, epidemiologiji te geografskoj rasprostranjenosti. Rasprostranjenost Tipa A uglavnom je ograničena na sjevernoamerički kontinent, za razliku od Tipa B, koji se javlja duž cijele sjeverne polutke, a ujedno je i najčešći uzročnik tularemije u Europi(Keim et al., 2007; Kuehn et al., 2013). No ekologija i kruženje ove bakterije u prirodi do danas još nisu u potpunosti razjašnjeni. Različiti glodavci (voluharice, miševi, tekunice, bizantski štakori, dabrovi) te dvojezupci (kunić i zec) opisani su kao mogući rezervoari F.tularensis. Zadnja epidemiološka i epizootiološka istraživanja tularemije u Hrvatskoj datiraju iz šezdesetih i sedamdesetih godina prošloga stoljeća(Borcić et al., 1975). Stoga je cilj ovoga rada bio prikupiti nove podatke o prevalenciji tularemije u populaciji sitnih sisavaca u Hrvatskoj. Ukupno 444 uzoraka sitnih glodavaca i kukcojeda sakupljeno je u razdoblju od dvije godine na osam različitih lokaliteta u šumama kontinentalne Hrvatske: Lipovljani, Nova Subocka, Velika Gorica, Stara Gradiška, Županja, Sunja, Koprivnica i Čakovec (Slika 1). Pretraženi su uzorci slezene od: 197 Apodemus agrarius (poljski miš), 78 Apodemus sylvaticus (šumski miš), 92 Apodemus flavicollis (žutogrli miš), 17 Myodes glareolus (šumska voluharica), 27 Mycrotus agrestis (livadna voluharica), 20 Microtus arvalis (poljska voluharica) te 13 Sorex araneus (rovka). Uzorcisu pretraženi na prisutnost DNA Francisella spp. koristeći qRT-PCR metodu. Dobiveni rezultati pokazuju da su od ukupno 444 prikupljene životinje tri uzorka (0.67%), od kojih dva poljska miša te jedan šumski miš, bili pozitivni su na francizelu (Tablica 1). Sva tri pozitivna uzorka prikupljena su na istom području – lokalitetu Lipovljani. Tularemija je bolest koja se primarno povezuje s „nizinskim“ i „vodenim“ ekosustavima (Borcić, 1973). Područje duž toka rijeke Save (Posavina) opisuje se kao prirodno žarište tularemije u Hrvatskoj (Borcic et al., 1976), akao glavni rezervoar tularemije na tom području navodi se poljska voluharica (Borcic et al., 1976). Trimiša pozitivna na F. tularensis upućuju da je ova bakterija i dalje prisutna u populaciji sitnih glodavaca u Hrvatskoj. Nadalje, svi pozitivni uzorci prikupljeni su na lokalitetu Lipovljani, smještenom u srednjem dijelu toka rijeke Save, stoga ova regija zadržava obilježje prirodnog žarišta tularemije u Hrvatskoj.

Polylepis forest, historically widespread throughout high elevations of the central and northern Andes, now remain only in discontinuous small patches.  An expanding agricultural frontier, along with other anthropogenic pressures, imperils these remnants through further isolation and loss of habitat quality. Using two grids of live traps we compared the populations of small nonvolant mammals in an intact Polylepis woodland with one nearby that had been logged 50 years before. Our study is the first to examine the effects of habitat degradation and associated changes to vertical complexity and habitat heterogeneity on mammalian communities in Polylepis woodlands above 3500 m. The intact woodland had significantly more vertical complexity than the mid-successional woodland.  A total of 315 captures of 147 individuals of 9 species were sampled during an intensive trapping effort in 2010.  Trap success was especially high averaging 35.4 % and 28.1 % in the intact and mid-successional woodland, respectively.  Diversity and abundance of small mammals were greater in the intact woodland than the mid-successional site.  Forest specialist species were more abundant in the intact habitat; while Thomasomys paramorum, a habitat generalist, was dominant in both.  Habitat quality affected movement patterns of T. paramorum.  The results affirm a high diversity and density of small mammals in intact Polylepis woodland and indicate that the effects of habitat disturbance are species dependent.  We suggest that habitat specialists are more susceptible to loss of habitat heterogeneity and vertical complexity than habitat generalists.

The degree of penetration of urban habitats by small terrestrial mammals was studied in Warsaw agglomeration and in adjacent areas up to 50 km from the city centre. Study material consisted of pellets of the tawny owl Strix aluco collected in 85 sites, which contained 15,152 remains of individuals of small mammals. The species that penetrated city agglomeration most intensively were: Apodemus agrarius, Mus musculus, Talpa europaea, Rattus norvegicus and Microtus subterraneus. Most central sites of these species were situated 1.3–2.3 km from the city centre. Microtus agrestis, Mustela nivalis, Arvicola amphibius, Neomys fodiens, Muscardinus avellanarius and Sicista betulina showed the lowest degree of penetration of an urban agglomeration (sites closest to the city centre: 8.2, 8.6, 8.6, 11.2, 17.8 and 20.2 km, respectively). Species, whose share among the owls’ prey decreased most with the distance from the city centre, were: A. agrarius and T. europaea. The reverse pattern was found for M. agrestis and M. avellanarius. Small terrestrial mammals are sensitive to the proceeding urbanization and the central part of Warsaw agglomeration is penetrated by only 1/3 of species of the local fauna.

AbstractLogging and mining are widespread in most West African countries and considering their socio-economic importance, little is known about their ecological impacts. In this study, we investigated the effects of chainsaw milling (logging) and artisanal mining on terrestrial small mammal communities in a tropical forest in Ghana. For this, we compared abundance, diversity measures and community composition of small mammals active at the forest floor in logged, mined and undisturbed forest sites. We found that abundance was higher in logged and undisturbed forest sites than in mined sites. Small mammal species richness, Shannon diversity and Pielou’s evenness did not differ significantly among the three forest disturbance categories. Community composition of small mammals varied between mined and undisturbed sites as well as between mined and logged sites, suggesting differential species responses to altered environments. This may be due to the presence of pits in mined forest sites, hence a reduction in exploitable ground habitat structures for shelter, nesting or food. Overall, our results suggest that artisanal mining has strong impacts on community composition of forest floor small mammals in tropical forests while the effect of logging by chainsaw milling activities is minimal, especially when practiced at low intensity. This effect was moderated by elevation and distance to streams that equally shaped small mammal communities. More research on the effects of specific forms of logging and mining activities on small mammals are urgently needed to better protect species in forests impacted by logging and mining.
