| novel hantavirus in the flat-skulled shrew (sorex roboratus). | genetically distinct hantaviruses have been identified recently in multiple species of shrews (order soricomorpha, family soricidae) in eurasia and north america. to corroborate decades-old reports of hantaviral antigens in shrews from russia, archival liver and lung tissues from 4 siberian large-toothed shrews (sorex daphaenodon), 5 eurasian least shrews (sorex minutissimus), 12 flat-skulled shrews (sorex roboratus), and 18 tundra shrews (sorex tundrensis), captured in the sakha republic in nor ... | 2010 | 20426682 |
| seewis virus: phylogeography of a shrew-borne hantavirus in siberia, russia. | hantaviral antigens were originally reported more than 20 years ago in tissues of the eurasian common shrew (sorex araneus), captured in european and siberian russia. the recent discovery of seewis virus (swsv) in this soricid species in switzerland provided an opportunity to investigate its genetic diversity and geographic distribution in russia. | 2010 | 20426688 |
| karyotype evolution of eulipotyphla (insectivora): the genome homology of seven sorex species revealed by comparative chromosome painting and banding data. | the genus sorex is one of the most successful genera of eulipotyphla. species of this genus are characterized by a striking chromosome variability including xy1y2 sex chromosome systems and exceptional chromosomal polymorphisms within and between populations. to study chromosomal evolution of the genus in detail, we performed cross-species chromosome painting of 7 sorex species with s. granarius and s. araneus whole-chromosome probes and found that the tundra shrew s. tundrensis has the most rea ... | 2011 | 21912114 |
| species of coccidia (apicomplexa: eimeriidae) in shrews from alaska, u.s.a., and northeastern siberia, russia, with description of two new species. | fecal samples (n = 636) from 10 species of shrews collected in alaska (n = 540) and northeastern siberia (n = 96) were examined for the presence of coccidia (apicomplexa: eimeriidae). five distinct oocyst morphotypes were observed. three types were consistent with oocysts of previously recognized coccidia species from other shrew hosts. these were eimeria inyoni, e. vagrantis, and isospora brevicauda, originally described from the inyo shrew (sorex tenellus), dusky shrew (s. monticolus), and nor ... | 2008 | 18576829 |
| two new cestode species of neoskrjabinolepis spasskii, 1947 (cyclophyllidea: hymenolepididae) from the tundra shrew sorex tundrensis merriam (mammalia: soricidae) in alaska and chukotka. | descriptions, illustrations and differential diagnoses for two new species of neoskrjabinolepis spassky, 1947, i.e. n. (neoskrjabinolepis) fertilis n. sp. and n. (neoskrjabinolepidoides) hobergi n. sp., are given. neoskrjabinolepis (neoskrjabinolepis) fertilis was found in the shrew sorex tundrensis merriam on the seward peninsula (alaska, usa) and from the mouth of the anadyr river (chukotka, russia), and n. (neoskrjabinolepidoides) hobergi was found in sorex tundrensis on the seward peninsula ... | 2012 | 23065302 |
| effects of late quaternary climate change on palearctic shrews. | the late quaternary was a time of rapid climatic oscillations and drastic environmental changes. in general, species can respond to such changes by behavioral accommodation, distributional shifts, ecophenotypic modifications (nongenetic), evolution (genetic) or ultimately face local extinction. how those responses manifested in the past is essential for properly predicting future ones especially as the current warm phase is further intensified by rising levels of atmospheric carbon dioxide. here ... | 2013 | 23505017 |
| persistence and diversification of the holarctic shrew, sorex tundrensis (family soricidae), in response to climate change. | environmental processes govern demography, species movements, community turnover and diversification and yet in many respects these dynamics are still poorly understood at high latitudes. we investigate the combined effects of climate change and geography through time for a widespread holarctic shrew, sorex tundrensis. we include a comprehensive suite of closely related outgroup taxa and three independent loci to explore phylogeographic structure and historical demography. we then explore the im ... | 2011 | 21919986 |
| sequencing and analysis of the complete mitochondrial genome of tundra shrew (sorex tundrensis) from china. | the complete mitogenome sequence of tundra shrew (sorex tundrensis) was determined using long pcr. the genome was 17,444 bp in length and contained 13 protein-coding genes, 2 ribosomal rna genes, 23 transfer rna genes, 1 origin of l strand replication and 1 control region. the overall base composition of the heavy strand is a (32.9%), c (24.8%), t (29.0%), and g (13.3%). the base compositions present clearly the a-t skew, which is most obviously in the control region and protein-coding genes. th ... | 2016 | 25812054 |
| co-circulation of distinct shrew-borne hantaviruses in the far east of russia. | insectivores are the new emerging reservoir of hantaviruses. here, we describe lena virus (lenv), a novel hantavirus harbored by the laxmann`s shrew (sorex caecutiens), which is also the host of artybash virus (artv). genetic analysis of the complete genomic sequence shows that lenv is in distant relation to artv and other sorex-borne hantaviruses, suggesting that lenv has emerged from cross-species transmission. additionally, new genetic variant of artv, designated as artv-st, was identified in ... | 2019 | 31422116 |
| geographic distribution and phylogeny of soricine shrew-borne seewis virus and altai virus in russia. | the discovery of genetically distinct hantaviruses (family hantaviridae) in multiple species of shrews, moles and bats has revealed a complex evolutionary history involving cross-species transmission. seewis virus (swsv) is widely distributed throughout the geographic ranges of its soricid hosts, including the eurasian common shrew (sorex araneus), tundra shrew (sorex tundrensis) and siberian large-toothed shrew (sorex daphaenodon), suggesting host sharing. in addition, genetic variants of swsv, ... | 2021 | 34372492 |
