Are the Western water shrew ( Sorex navigator ) and American water shrew ( Sorex palustris ) morphologically distinct
Canadian Journal of Zoology, 2017Co-Authors: David W. Nagorsen, Nick Panter, Andrew G. HopeAbstract:Recent phylogenetic studies applying the mitochondrial Cytb gene and nuclear genes revealed divergent cordilleran and boreal lineages in western populations of the Sorex palustris complex that are now recognized as distinct species: Sorex navigator (Baird, 1858) (Western water shrew), Sorex palustris Richardson, 1828 (American water shrew). Their distributions in western Canada are parapatric with a potential contact zone in the foothills of the Rocky Mountains. Using 80 specimens including 69 of known genotype, we assessed morphological differentiation in metric and non-metric traits among S . navigator , S . palustris , and S . bendirii (Merriam, 1894) (marsh shrew) a sister species of S. navigator. Multivariate analyses revealed discrete morpho groups concordant with their genetic lineages and species level divergence. Three individuals from northwestern British Columbia and one from southwestern Alberta with discorda...

Novel Hantavirus in the Flat-Skulled Shrew (Sorex roboratus)
Vector-Borne and Zoonotic Diseases, 2010Co-Authors: Hae Ji Kang, Satoru Arai, Andrew G. Hope, Joseph A. Cook, Richard YanagiharaAbstract:Abstract 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 northeastern Siberia during July and August 2006, were analyzed for hantavirus RNA by reverse transcription–polymerase chain reaction. A novel hantavirus, named Kenkeme virus, was detected in a flat-skulled shrew. Sequence analysis of the full-length S and partial M and L segments indicated that Kenkeme virus was genetically and phylogenetically distinct from Seewis virus harbored by the Eurasian common shrew (Sorex araneus), as well as all other rodent-, soricid-, and talpid-borne hantaviruses.

Phylogenetically distinct hantaviruses in the masked shrew (Sorex cinereus) and dusky shrew (Sorex monticolus) in the United States.
The American Journal of Tropical Medicine and Hygiene, 2008Co-Authors: Satoru Arai, Andrew G. Hope, Joseph A. Cook, Jin-won Song, Shannon N. Bennett, Laarni Sumibcay, Cheryl A. Parmenter, Vivek R. Nerurkar, Terry L. Yates, Richard YanagiharaAbstract:A limited search for hantaviruses in lung and liver tissues of Sorex shrews (family Soricidae, subfamily Soricinae) revealed phylogenetically distinct hantaviruses in the masked shrew (Sorex cinereus) from Minnesota and in the dusky shrew (Sorex monticolus) from New Mexico and Colorado. The discovery of these shrew-borne hantaviruses, named Ash River virus and Jemez Springs virus, respectively, challenges the long-held dogma that rodents are the sole reservoir hosts and forces a re-examination of their co-evolutionary history. Also, studies now underway are aimed at clarifying the epizootiology and pathogenicity of these new members of the genus Hantavirus.

Revision of the genus Soricinia Spassky & Spasskaja, 1954 (Cestoda: Cyclophyllidea: Hymenolepididae) with redescriptions of three species, an amended generic diagnosis and an identification key to species
Systematic Parasitology, 2016Co-Authors: Svetlana Kornienko, Rasa Binkienė, Vasyl V TkachAbstract:Redescriptions of three species of Soricinia Spassky & Spasskaja, 1954 are provided. The type-species of the genus, Soricinia soricis (Baer, 1925), is redescribed on the basis of the holotype from the Alpine shrew Sorex alpinus Schinz collected in Salève Mountain, France. Since the type-material of Soricinia infirma (Żarnowski, 1955) has apparently been lost, a neotype from the type-host Sorex araneus L. and from a region reasonably close to the type-locality (Poltavska Oblast’ in the Ukraine), is designated. The type-material of Soricinia quarta (Karpenko, 1983) Karpenko, 1999 from Sorex isodon Turov in Khabarovsk Kray (Russia) is redescribed. A taxonomic revision and an overview of the geographical distribution of species of the genus Soricinia are presented. An amended generic diagnosis and a key to identification of Soricinia spp. are also presented.

molecular identification of an avian dicrocoeliid brachylecithum mosquensis from a vagrant shrew Sorex vagrans in montana u s a
Comparative Parasitology, 2009Co-Authors: John M. Kinsella, Vasyl V TkachAbstract:Gravid dicrocoeliid flukes recovered from the liver of a vagrant shrew, Sorex vagrans, in Montana, U.S.A., were identified as Brachylecithum mosquensis by comparing their morphology and DNA sequences to specimens from 2 American robins, Turdus migratorius, from North Dakota, U.S.A. This is the first record in the world, to our knowledge, of a bird dicrocoeliid from a shrew and also the first record in North America of a dicrocoeliid parasitic in the genus Sorex.

Molecular phylogeny of long-tailed shrews (genus Sorex) from México and Guatemala
Zootaxa, 2010Co-Authors: Martha Esteva, Fernando A. Cervantes, Sara V. Brant, Joseph A. CookAbstract:We present a molecular phylogeny of North American species of long-tailed shrews of the genus Sorex. Our focus is on Mexican and Guatemalan species to begin understanding their evolutionary relationships and to test the validity of nominal species. Seventy-seven sequences of the mitochondrial cytochrome b gene were analyzed, including 19 specimens representing nine Mexican and one Guatemalan species. Phylogenetic analyses using parsimony, maximum likelihood and Bayesian approaches revealed two major clades of North American species, all within the subgenus OtiSorex. The first major clade includes S. trowbridgii and southern species (S. macrodon from Oaxaca; S. veraecrucis from Nuevo Leon, Michoacan, Chiapas, S. saussurei from Jalisco and Guatemala; S. veraepacis from Guerrero and Guatemala). Relatively deep branches among taxa characterize this clade and suggest that their early divergence from other North American shrews was soon after arrival of the ancestral stock from the Beringian region. The other major clade includes all other North American species of Sorex we examined, with two Mexican species, S. milleri and S. emarginatus, grouped in a subclade with the S. cinereus complex. Sorex veraecrucis is not, however, a monophyletic taxon because specimens of this nominal species were included in both the major clades. The Isthmus of Tehuantepec has likely played a role as a biogeographic barrier in the evolutionary history of Mexican shrews. This study of mitochondrial variation in southern North American shrews of the genus Sorex indicates there is substantial, previously undetected diversity that necessitates a revision of the taxonomy of S. veraecrucis and S. veraepacis.
