basal rate of metabolism and temperature regulation in sorex coronatus and s. minutus (soricidae: mammalia).	1. the basal rate of metabolism (bmr), body temperature and thermal conductance of sorex minutus and sorex coronatus were studied. special attention was given to measuring bmr in resting and postabsorptive shrews. 2. both species exhibit a high bmr, respectively 339 and 289% of the value expected on the basis of body mass. 3. the thermal conductance of both species is similar to the predicted value and their body temperature averages 38.6 and 37.6 degrees c respectively. 4. available data sugges ...	1989	2565786
genetic and karyotypic structure in the shrews of the sorex araneus group: are they independent?	the species of the common shrew (sorex araneus) group are morphologically very similar but exhibit high levels of karyotypic variation. here we used genetic variation at 10 microsatellite markers in a data set of 212 individuals mostly sampled in the western alps and composed of five karyotypic taxa (sorex coronatus, sorex antinorii and the s. araneus chromosome races cordon, bretolet and vaud) to investigate the concordance between genetic and karyotypic structure. bayesian analysis confirmed t ...	2006	16629812
tick-borne zoonotic bacteria in wild and domestic small mammals in northern spain.	the prevalence and diversity of tick-borne zoonotic bacteria (borrelia spp., anaplasma phagocytophilum, coxiella burnetii, and spotted fever group rickettsiae) infecting 253 small mammals captured in the basque country (spain) were assessed using pcr and reverse line blot hybridization. trapping sites were selected around sheep farms (study 1, 2000 to 2002) and recreational parks (study 2, 2003 to 2005). the majority of the studied mammals (162) were wood mice (apodemus sylvaticus), but six othe ...	2007	17693556
relationships of basal metabolic rate, relative testis size and cycle length of spermatogenesis in shrews (mammalia, soricidae).	the aim of the present study was to determinate the cycle length of spermatogenesis in three species of shrew, suncus murinus, sorex coronatus and sorex minutus, and to assess the relative influence of variation in basal metabolic rate (bmr) and mating system (level of sperm competition) on the observed rate of spermatogenesis, including data of shrew species studied before (sorex araneus, crocidura russula and neomys fodiens). the dynamics of sperm production were determined by tracing 5-bromod ...	2008	18402763
mass effects mediate coexistence in competing shrews.	recent developments in metacommunity theory have raised awareness that processes occurring at regional scales might interfere with local dynamics and affect conditions for the local coexistence of competing species. four main paradigms are recognized in this context (namely, neutral, patch-dynamics, species-sorting, and mass-effect), which differ according to the role assigned to ecological or life-history differences among competing species, as well as to the relative time scale of regional vs. ...	2008	18705388
cornea, retina, and lens morphology in five soricidae species (soricomorpha: mammalia).	we analyzed the cornea, retina, and lens of five species of soricidae (pygmy shrew, sorex minutus; common shrew, sorex araneus; millet's shrew, sorex coronatus; water shrew, neomys fodiens; greater white-toothed shrew, crocidura russula) by light and electron microscopy. in all of these species, the corneal epithelium showed a dead cell layer, which may increase the refractive power of the cornea, thereby reducing the hypermetropy that would be expected in a small eye. moreover, the anterior sur ...	2009	19367448
chromosomal versus mitochondrial dna evolution: tracking the evolutionary history of the southwestern european populations of the sorex araneus group (mammalia, insectivora).	the shrews of the sorex araneus group have undergone a spectacular chromosome evolution. the karyotype of sorex granarius is generally considered ancestral to those of sorex coronatus and s. araneus. however, a sequence of 777 base pairs of the cytochrome b gene of the mitochondrial dna (mtdna) produces a quite different picture: s. granarius is closely related to the populations of s. araneus from the pyrenees and from the northwestern alps, whereas s. coronatus and s. araneus from italy and th ...	1994	28568274
novel polyomaviruses in shrews (soricidae) with close similarity to human polyomavirus 12.	shrews (family soricidae) have already been reported to host microorganisms pathogenic for humans. in an effort to search for additional infectious agents with zoonotic potential, we detected polyomaviruses (pyvs) in common shrew, crowned shrew, and pygmy shrew (sorex araneus, s. coronatus and s. minutus). from these, 11 full circular genomes were determined. phylogenetic analysis based on large t protein sequences showed that these novel pyvs form a separate clade within the genus alphapolyomav ...	2017	29095685
protocol for the reconstruction of micromammals from fossils. two case studies: the skulls of beremendia fissidens and dolinasorex glyphodon.	we have developed a protocol for reconstructing 3d models of the skulls of extinct species of small mammals. for the first time, the reconstruction uses fragments of fossils from a mixture of different specimens and from related extant species. we use free software and commercial computers to make the process reproducible and usable for the scientific community. we present a semi-quantitative protocol to face the problem of making 3d reconstructions of fossil species that are incomplete in the f ...	2019	30893322
highly diversified shrew hepatitis b viruses corroborate ancient origins and divergent infection patterns of mammalian hepadnaviruses.	shrews, insectivorous small mammals, pertain to an ancient mammalian order. we screened 693 european and african shrews for hepatitis b virus (hbv) homologs to elucidate the enigmatic genealogy of hbv. shrews host hbvs at low prevalence (2.5%) across a broad geographic and host range. the phylogenetically divergent shrew hbvs comprise separate species termed crowned shrew hbv (cshbv) and musk shrew hbv (mshbv), each containing distinct genotypes. recombination events across host orders, evolutio ...	2019	31371507
