| [geography of chromosomes of natural populations of the shrews sorex araneus and suncus murinus]. | the geographic distribution of chromosome races of two shrew species (sorex araneus and suncus murinus) was analyzed on the basis of published data and personal results. it was shown that expansion of both species was accompanied by fixation of different chromosome rearrangements (mainly robertsonian translocations) in isolates. chromosome polymorphism studied from the viewpoint of ecology and geography of these species allows reconstruction of their evolutionary history and understanding of the ... | 1997 | 9378305 |
| disturbances of the mineral incorporation in various species of mice and shrews in the emission area of a phosphate plant. | the cd emission of a phosphate plant was clearly reflected by the cd status of herbivorous european wood mice and common field voles as well as of european shrews taking in mostly animal food. the antagonistic effect of the emitted cd and mo better available for plants with high ground ph most probably caused the deterioration in the cu status of the animals of both phases in the nutritional chain. the lower ca, p, and mg incorporation with european wood mouse and common field vole within the co ... | 1997 | 9404674 |
| meiosis and fertility in common shrews, sorex araneus, from a chromosomal hybrid zone in central sweden. | adult male common shrews from the uppsala and hällefors robertsonian chromosomal races and hybrids were collected from the area of surahammar in sweden. meiosis and fertility of hybrid (complex heterozygotes) and nonhybrid (homozygotes) individuals were compared based on an analysis of chromosomal interactions and synapsis at pachytene, chiasma characteristics at diakinesis, and germ-cell death. no individuals suffered severe germ-cell loss, and the differences found among the uppsala and hällef ... | 1997 | 9465899 |
| serosurvey for orthopoxviruses in rodents and shrews from norway. | two hundred and twenty one blood samples representing eight different rodent species and the common shrew (sorex araneus), collected in norway between 1993 and 1995, were examined for anti-orthopoxvirus antibodies by a competition enzyme linked imunnosorbent assay (elisa) and, when possible, an indirect immunofluorescence assay. the serological results indicated that the bank vole (clethrionomys glareolus), woodmouse (apodemus sylvaticus) and norway lemming (lemmus lemmus) may be reservoir speci ... | 1998 | 9577770 |
| [chromosomal localization of nine genes in common shrew (sorex araneus)]. | syntheny and localization of the following genes in common shrew sorex araneus were determined: isocitrate dehydrogenase 2 (idh2), acid phosphatase 2 (acp2), glutamine--pyruvate--oxo-acid transaminase (gpt), and inorganic pyrophosphatase (pp) on chromosome ik; adenylate kinases 1 and 3 (ak1 and ak3) on chromosome af; and enolase 1 (eno1) on chromosome jl. two genes were assigned to definite arms: aminoacylase 1 (acy1) to arm p of chromosome mp and glutamic-oxaloacetic transaminase 1 (got1) to ar ... | 1998 | 9589866 |
| muscle capillary supply in hind limb and diaphragm of the common shrew (sorex araneus). | shrew species of the subfamily soricinae have unusually high metabolic rates when compared to crocidurinae shrews and other similar-sized mammals. the aim of this study was to clarify whether the high basal metabolic rate of soricinae shrews is reflected in a high capillary density in their muscles. to this end, the capillary supply of four limb muscles and diaphragm of the common shrew (sorex araneus) was quantified from cross-sectioned muscles. the capillary densities of the limb muscles were ... | 1998 | 9646505 |
| zoo-fish analysis in insectivores: "evolution extols the virtue of the status quo". | in evolutionary terms, insectivores are thought to be close to primates. through zoo-fish analysis using human chromosome-specific painting probes, the syntenic relationship between the human and common shrew, sorex araneus, karyotypes was studied. the human karyotype was found to be conserved in the shrew, with 32 autosomal segments of common synteny. special arrangements, already known from similar studies on other species, were noted: fusions of hsa 16 and 19, hsa 3 and 21, and hsa 14 and 15. ... | 1998 | 9678336 |
| spermatogenesis in common shrews, sorex araneus, from a hybrid zone with extensive robertsonian polymorphism. | the analysis of the fertility of hybrid and nonhybrid individuals from a chromosomal contact zone gives us the possibility of studying the role of chromosomes in speciation processes. in this study, homozygous, "simple" and "complex" robertsonian heterozygous male common shrews (sorex araneus) from the abisko-sidensjö chromosomal hybrid zone in sweden were analysed. the degree of germ cell death was estimated, sperm counts were performed and the testis and seminal vesicles weighed in each indivi ... | 1998 | 9678351 |
| naturally occurring orthopoxviruses: potential for recombination with vaccine vectors. | orthopoxviruses are being increasingly used as live recombinant vectors for vaccination against numerous infectious diseases in humans, domestic animals, and wildlife. for risk assessments and surveillance, information about the occurrence, distribution and ecology of orthopoxviruses in western europe is important but has mainly been based on serological investigations. we have examined kidneys, lungs, spleens, and livers of norwegian small rodents and common shrews (sorex araneus) for the prese ... | 1998 | 9705389 |
| [features of the parasitic system of ixodid ticks--borrelia--small mammals in the russian northwest]. | mammals and ticks was collected in 1995-1997 years in novgorod region from may to september. traps were exposed during 5 consecutive days every month in 4 different biotopes. 928 hosts were captured during three years. 357 larvae and 59 nymphs of ixodes persulcatus, 356 larvae and 71 nymphs of i. trianguliceps were collected. the clethrionomys glareolus and sorex araneus are main hosts of larvae of i. persulcatus and i. trianguliceps. c. glareolus feed 76.2% of i. persulcatus larvae and 25% of i ... | 1998 | 9859127 |
| seasonal dynamics of pneumocystis carinii in the field vole, microtus agrestis, and in the common shrew, sorex araneus, in finland. | seasonal dynamics of pneumocystis carinii in the field vole, microtus agrestis, and in the common shrew, sorex araneus, were investigated in southern and central finland by microscopical examination of methenamine silver-stained tissue sections. in both host species at both localities the number of p. carinii cyst forms was highest in late autumn (november). in s. araneus, prevalence was higher than in m. agrestis during all seasons. none of the animals was heavily infected or apparently ill, an ... | 1999 | 10070655 |
| meiotic drive favors robertsonian metacentric chromosomes in the common shrew (sorex araneus, insectivora, mammalia). | meiotic drive has attracted much interest because it concerns the robustness of mendelian segregation and its genetic and evolutionary stability. we studied chromosomal meiotic drive in the common shrew (sorex araneus, insectivora, mammalia), which exhibits one of the most remarkable chromosomal polymorphisms within mammalian species. the open question of the evolutionary success of metacentric chromosomes (robertsonian fusions) versus acrocentrics in the common shrew prompted us to test whether ... | 1998 | 10072577 |
| emmonsiosis of wild rodents and insectivores in czechland. | adiaspores of the fungus emmonsia crescens were detected microscopically in the lung tissue of 13% of 10.081 small mammals belonging to 24 species examined in 14 areas of the czech republic between 1986 and 1997; 441/1.934 (23%) clethrionomys glareolus, 1/6 (17%) arvicola terrestris, 357/2.172 (16%) apodemus flavicollis, 220/1.981 (11%). a sylvaticus, 23/265 (9%) a. microps, 11/81 (14%) microtus subterraneus, 93/1.275 (7%) m. arvalis, 98/1.439 (7%) m. agrestis, 1/3 (33%) ondatra zibethicus, 1/1 ... | 1999 | 10231750 |

| [chromosomal localization of 10 genes on the cytogenetic map of the common shrew sorex araneus l]. | using a panel of hybrid clones (common shrew--chinese hamster and common shrew--mouse), the syntheny and localization of the following genes was determined: genes for alpha-galactosidase (gla), acid phosphatase (acp1), and phosphoglycerate kinase (pgk1) on chromosome de; adenosine kinase (adk) and glucuronidase 2 (gus2) on chromosome ik; glutamic-oxaloacetic transaminase 2 (got2) and peptidase d (pepd) on chromosome hn; and glyoxalase 1 (glo1) and phosphoglucomutase 2 (pgm2) on chromosome go. ge ... | 1999 | 10420272 |
| do riverine barriers, history or introgression shape the genetic structuring of a common shrew (sorex araneus) population? | the common shrew (sorex araneus) is subdivided into numerous chromosome races. the valais and cordon chromosome races meet and hybridize at a mountain river in les houches (french alps). significant genetic structuring was recently reported among populations found on the valais side of this hybrid zone. in this paper, a phylogenetic analysis and partial mantel tests are used to investigate the patterns and causes of this structuring. a total of 185 shrews were trapped at 12 localities. all indiv ... | 1999 | 10469203 |
| the phylogenetic position of the talpidae within eutheria based on analysis of complete mitochondrial sequences. | the complete mitochondrial (mt) genome of the mole talpa europaea was sequenced and included in phylogenetic analyses together with another lipotyphlan (insectivore) species, the hedgehog erinaceus europaeus, and 22 other eutherian species plus three outgroup taxa (two marsupials and a monotreme). the phylogenetic analyses reconstructed a sister group relationship between the mole and fruit bat artibeus jamaicensis (order chiroptera). the talpa/artibeus clade constitutes a sister clade of the ce ... | 2000 | 10666706 |
| pcr detection of granulocytic ehrlichiae in ixodes ricinus ticks and wild small mammals in western switzerland. | the presence of granulocytic ehrlichiae was demonstrated by pcr in ixodes ricinus ticks and wild small mammals in switzerland in two areas of endemicity for bovine ehrlichiosis. six ticks (three females and three nymphs) (1.4%) of 417 i. ricinus ticks collected by flagging vegetation contained ehrlichial dna. a total of 201 small mammals from five species, wood mouse (apodemus sylvaticus), yellow-necked mouse (apodemus flavicollis), earth vole (pitymys subterraneus), bank vole (clethrionomys gla ... | 2000 | 10698987 |
| a comparison of spermatogenesis in homozygotes, simple robertsonian heterozygotes and complex heterozygotes of the common shrew (sorex araneus l.). | spermatogenesis was studied in 56 shrews (sorex araneus l.) from two chromosomal hybrid zones in poland. the hybrid zones were formed between chromosome races that differed in robertsonian metacentrics. shrews were compared in four classes: homozygotes, simple robertsonian heterozygotes, complex heterozygotes forming four-element rings in meiosis i, and complex heterozygotes forming four- or five-element chains. there was a significant effect of karyotype on the level of germ-cell death and chai ... | 2000 | 10849082 |
| seasonality of leptin levels in the bat of the common shrew (sorex araneus). | leptin concentrations in the interscapular brown adipose tissue (ibat) of the common shrew (sorex araneus) were measured in different seasons. the leptin concentrations in ibat were much higher than in the liver, where leptin is supposed to be of blood origin. in the heart muscle no detectable amount of leptin was found. there were clear seasonal variations in the leptin concentrations in ibat. leptin levels in ibat were the lowest in november at the beginning of the winter. the concentrations i ... | 2009 | 10928559 |
| microsatellites can be misleading: an empirical and simulation study. | it has been long recognized that highly polymorphic genetic markers can lead to underestimation of divergence between populations when migration is low. microsatellite loci, which are characterized by extremely high mutation rates, are particularly likely to be affected. here, we report genetic differentiation estimates in a contact zone between two chromosome races of the common shrew (sorex araneus), based on 10 autosomal microsatellites, a newly developed y-chromosome microsatellite, and mito ... | 2000 | 11005307 |
| photoreceptor types and distributions in the retinae of insectivores. | the retinae of insectivores have been rarely studied, and their photoreceptor arrangements and expression patterns of visual pigments are largely unknown. we have determined the presence and distribution of cones in three species of shrews (common shrew sorex araneus, greater white-toothed shrew crocidura russula, dark forest shrew crocidura poensis; soricidae) and in the lesser hedgehog tenrec echinops telfairi (tenrecidae). special cone types were identified and quantified in flattened whole r ... | 2008 | 11193110 |
| findings of mycobacteria in insectivores and small rodents. | the organs of 30 insectivorous mammals and 62 rodents from areas inhabited by people or livestock where cattle paratuberculosis or mycobacterial infections of swine had been found to occur were examined by cultivation during the monitoring of occurrence and spread of mycobacterioses in cattle and swine. mycobacteria were found in the organs of 3 insectivores (10%) and 6 rodents (9.7%). mycobacterium chelonae was isolated from the organs of the lesser white-toothed shrew (crocidura suaveolens) an ... | 2000 | 11271823 |
| [chromosomal evolution of the common shrew sorex araneus l.from the southern ural and siberia in the postglacial period]. | this paper summarizes a series of studies on chromosomal geography of the common shrew sorex araneus l. in siberia and the southern urals. chromosomal races inhabiting the southern urals and the western siberian plain sequentially replace each other in the latitudinal direction. in this region, karyotypes of each two adjacent races differ from each other by a single whole-arm reciprocal translocation. in the eastern siberian branch, the neighboring races differ mainly in the number or set of met ... | 2001 | 11421117 |
| importance of surveillance of tularemia natural foci in the known endemic area of central europe, 1991-1997. | marked activation of natural foci of tularemia in the known endemic area of central europe, comprising the borderland of slovakia, austria and the czech republic, led to an epidemic outbreak in western slovakia and an increase in the number of human tularemia cases in the adjoining regions of northeastern austria and southern moravia from 1995 to 1997. the aim of this paper was to present the results of a longitudinal study on the prevalence of infection with francisella tularensis in small mamm ... | 2001 | 11467089 |

| short interspersed elements (sines) from insectivores. two classes of mammalian sines distinguished by a-rich tail structure. | four trna-related sine families were isolated from the genome of the shrew sorex araneus (sor element), mole mogera robusta (tal element), and hedgehog mesechinus dauuricus (eri-1 and eri-2 elements). each of these sines families is specific for a single insectivora family: sor, for soricidae (shrews); tal, for talpidae (moles and desmans); eri-1 and eri-2, for erinaceidae (hedgehogs). there is a long polypyrimidine region (tc-motif) in tal, eri-1, and eri-2 elements located immediately upstream ... | 2001 | 11668393 |
| effects of ash application on cadmium concentration in small mammals. | in order to assess the effects of wood ash application to forests on small mammals, we collected bank voles (clethrionomys glareolus) and common shrews (sorex araneus) from a forest area in southern finland. part of the sample population was from sites that had been treated with ash 1.5 years earlier, part from untreated control sites. the ash increased the soil ph and gave an average cadmium load in soil of 44 g ha(-1). when comparing treated and control areas, we found slightly but significant ... | 2013 | 11837422 |
| on morphological clocks and paleophylogeography: towards a timescale for sorex hybrid zones. | phylogeography--the study of within-species phylogenetic and geographic divergence--has been primarily the domain of molecular evolutionists because molecular markers record population structure on smaller scales than do traditional morphological traits. but when geometric morphometrics are combined with distance-based phylogenetics molar shape divergence appears to record population-level phylogeny, a fact that allows extant and fossil populations to be combined in a single phylogeographic stud ... | 2001 | 11838775 |
| [intraspecies phylogenetic connections in sorex araneus l.: a southern baltic subgroup of chromosome races]. | results of chromosome g-banding were used to identify two new karyotypic races of the common shrew (sorex araneus l.) in the european part of russia. the chromosomal diagnosis of race st. petersburg included five metacentrics (hk, ip, jl, mq, and nr) and two acrocentrics (g and o) (2na = 20); the diagnosis of race west dvina included six metacentrics (gm, hk, ip, jl, no, and qr) (2na = 18). the phylogenetic significance of the chromosomal markers gm, hk, and ip is considered and the possibility ... | 2002 | 11852798 |
| [involvement of the common shrew, sorex araneus (insectivora, soricidae), in circulation of the tick-borne encephalitis virus in south-western siberia]. | we presented the data on the abundance of immature instars of the taiga tick ixodes persulcatus schuize on the common shrews sorex araneus l. in natural foci of tick-borne encephalitis in the south of western siberia. basing on the results of virological and serological studies we demonstrated a low effectiveness of this host species as a donor of disease agent strains, which are predominant in the territory under study, for ticks feeding on shrews. the analysis of samples taken from the young s ... | 2001 | 11871252 |
| the evolutionary history of the two karyotypic groups of the common shrew, sorex araneus, in poland. | genetic variability within and among two karyotypic groups and five chromosome races of the common shrew (sorex araneus) in poland was assayed by sequencing a 1023 bp part of the cytochrome b gene (mtdna) from 28 individuals. thirty-four variable positions defined 21 distinct haplotypes with a maximum sequence divergence of 0.88%. no significant differentiation in the cytochrome b gene between western and eastern karyotypic groups was found. haplotype diversity estimates within the races and gro ... | 2002 | 11920129 |
| phylogeographical structure, postglacial recolonization and barriers to gene flow in the distinctive valais chromosome race of the common shrew (sorex araneus). | using one male-inherited and eight biparentally inherited microsatellite markers, we investigate the population genetic structure of the valais chromosome race of the common shrew (sorex araneus) in the central alps of europe. unexpectedly, the y-chromosome microsatellite suggests nearly complete absence of male gene flow among populations from the st-bernard and simplon regions (switzerland). autosomal markers also show significant genetic structuring among these two geographical areas. isolati ... | 2002 | 11972764 |
| fiber capillarization relative to mitochondrial volume in diaphragm of shrew. | the objective was to examine fiber capillarization in relation to fiber mitochondrial volume in the highly aerobic diaphragm of the shrew, the smallest mammal. the diaphragms of four common shrews [sorex araneus; body mass, 8.2 +/- 1.3 (se) g] and four lesser shrews (sorex minutus, 2.6 +/- 0.1 g) were perfusion fixed in situ, processed for electron microscopy, and analyzed by morphometry. capillary length per fiber volume was extremely high, at values of 8,008 +/- 1,054 and 12,332 +/- 625 mm(-2) ... | 2002 | 12070224 |
| the cerebellum at birth in therian mammals, with special reference to rodents. | the stage of cerebellar development at birth was assessed in 23 species of placental mammals. serial histological sections were examined and five stages in the differentiation of the cerebellar cortical layers were defined. a wide diversity of conditions at birth was found. the available evidence (after parsimony reconstruction) suggests that the last common ancestor of placentals was born with an altricial cerebellum in which the molecular layer was just present between the external granular la ... | 2002 | 12119530 |
| lack of a distinct gradient in biomarker responses in small mammals collected at different distances from a highway. | this study describes biomarker effects in small mammals exposed to traffic emissions. animals were collected at 10-50 m (site 1), 150-200 m (site 2), and 5 km (site 3) from a very busy highway (a2). to distinguish between routes of exposure, strictly carnivorous common shrews ( sorex araneus) and predominantly herbivorous bank voles ( clethrionomys glareolus) were collected. as a measure of exposure to polycyclic aromatic hydrocarbons (pahs), aromatic dna adduct levels were determined by (32)p-p ... | 2002 | 12202932 |
| meiotic studies of male common shrews (sorex araneus l.) from a hybrid zone between chromosome races. | thirty-three adult male common shrews (sorex araneus l.) were collected from a hybrid zone between two chromosomal races that differed in robertsonian metacentrics. anaphase i nondisjunction frequencies were estimated on the basis of metaphase ii counts. riv and cv complex heterozygotes (four-element rings and five-element chains at meiosis i, respectively) had substantially higher nondisjunction rates than homozygotes and simple robertsonian heterozygotes. however, at least in the case of riv-f ... | 2002 | 12438778 |
| alps, genes, and chromosomes: their role in the formation of species in the sorex araneus group (mammalia, insectivora), as inferred from two hybrid zones. | during the pleistocene glaciations, the alps were an efficient barrier to gene flow between isolated populations, often leading to allopatric speciation. afterwards, the alps strongly influenced the post-glacial recolonization of europe and represent a major suture zone between differentiated populations. two hybrid zones in the swiss and french alps between genetically and chromosomally well-differentiated species-the valais shrew, sorex antinorii, and the common shrew, s. araneus-were studied ... | 2002 | 12438784 |
| sex chromosome aneuploidy in wild small mammals. | we describe four examples of the xo condition in wild mammals. one xo house mouse (mus musculus domesticus) was caught in nature and subsequently gave birth to three litters in captivity, confirming for wild mice the fertility observed for xo laboratory mice. two other xo house mice were produced from laboratory crosses of wild-caught mice. an immature xo common shrew (sorex araneus) was caught in nature; this appears to be the first xo recorded in the order insectivora. we collected data from r ... | 2002 | 12438805 |

| risk assessment of metals and organic pollutants for herbivorous and carnivorous small mammal food chains in a polluted floodplain (biesbosch, the netherlands). | a risk assessment was made for a carnivorous and a herbivorous food chain in a heavily polluted natural estuary (biesbosch), by determining the most critical pollutants and the food chain most at risk. exposure of food chains to metals, polycyclic aromatic hydrocarbons (pahs), and polychlorinated biphenyls (pcbs) was assessed by analyzing dietary concentrations, internal concentrations, and biomarkers of exposure. common shrew (sorex araneus) and bank vole (clethrionomys glareolus) were selected ... | 2006 | 16530312 |
| cross-species chromosome painting unveils cytogenetic signatures for the eulipotyphla and evidence for the polyphyly of insectivora. | insectivore-like animals are traditionally believed among the first eutherian mammals that have appeared on the earth. the modern insectivores are thus crucial for understanding the systematics and phylogeny of eutherian mammals as a whole. here cross-species chromosome painting, with probes derived from flow-sorted chromosomes of human, was used to delimit the homologous chromosomal segments in two soricidae species, the common shrew (sorex araneus, 2n = 20/21), and asiatic short-tailed shrew ( ... | 2006 | 16544189 |
| is there an association of pneumocystis infection with the presence of arena-, hanta-, and poxvirus antibodies in wild mice and shrews in finland? | as part of studies on the nature of the endemic virus infections in natural rodent hosts, the possible association of cyst forms of pneumocystis spp. with the presence of hanta-, cowpox-, and arenavirus antibodies in wild mice (apodemus flavicollis, n=105; apodemus agrarius, n=63; micromys minutus, n=50) and the common shrew (sorex araneus, n=101) was studied in south-central finland. one hantavirus (saaremaa virus, saav) seropositive a. agrarius, and 2 cowpoxvirus (cpxv) seropositive s. araneus ... | 2006 | 16556344 |
| natural tick-borne encephalitis virus infection among wild small mammals in the southeastern part of western siberia, russia. | infestation of small mammals, including common shrews sorex araneus l., field mice apodemus agrarius pallas, and red voles clethrionomus rutilus schreber, with immature ixodes persulcatus ticks and their infection with tickborne encephalitis virus (tbev) were studied in the forest-steppe habitat in the vicinity of novosibirsk, russia. larval ticks parasitize all three host species, but virtually all nymphs were found only on field mice and red voles. detection of the viral rna using reverse tran ... | 2006 | 16584325 |
| speciation by monobrachial centric fusions. | fixation of centric fusions in natural populations often encounters minimal meiotic problems due to the ability of trivalents to segregate normally; therefore, little sterility barrier is achieved between a founder population and the parental stock. however, a strong sterility barrier can develop between different founder populations fixed for centric fusions that are monobrachially homologous in the resulting biarmed chromosomes (one arm is homologous but the other is nonhomologous). hybridizat ... | 1986 | 16593777 |
| chromosome localization of microsatellite markers in the shrews of the sorex araneus group. | the extremely high rate of karyotypic evolution that characterizes the shrews of the sorex araneus group makes this group an exceptionally interesting model for population genetics and evolutionary studies. here, we attempted to map 46 microsatellite markers at the chromosome arm level using flow-sorted chromosomes from three karyotypically different taxa of the sorex araneus group (s. granarius and the chromosome races cordon and novosibirsk of s. araneus). the most likely localizations were pr ... | 2006 | 16628496 |
| 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 |

| cycle length of spermatogenesis in shrews (mammalia: soricidae) with high and low metabolic rates and different mating systems. | the aim of the present study was to establish and compare the durations of the seminiferous epithelium cycles of the common shrew sorex araneus, which is characterized by a high metabolic rate and multiple paternity, and the greater white-toothed shrew crocidura russula, which is characterized by a low metabolic rate and a monogamous mating system. twelve s. araneus males and fifteen c. russula males were injected intraperitoneally with 5-bromodeoxyuridine, and the testes were collected. for cyc ... | 2007 | 17267697 |
| haemoparasites of common shrews (sorex araneus) in northwest england. | the presence of haemoparasites belonging to the taxa anaplasma, bartonella and trypanosoma was determined among 76 common shrews (sorex araneus) from northwest england. anaplasma phagocytophilum dna was recovered from the blood of 1 shrew (1.3%), with the amplified 16s rrna sequence identical to one previously reported from a bank vole (clethrionomys glareolus). trypanosoma spp. dna was detected in 9 shrews (11.8%), the amplified 18s rdna fragments being indistinguishable from one another, and d ... | 2007 | 17288633 |
| heavy-metal concentrations in small mammals from a diffusely polluted floodplain: importance of species- and location-specific characteristics. | the soil of several floodplain areas along large european rivers shows increased levels of heavy metals as a relict from past sedimentation of contaminants. these levels may pose risks of accumulation in food webs and toxicologic effects on flora and fauna. however, for floodplains, data on heavy-metal concentrations in vertebrates are scarce. moreover, these environments are characterised by periodical flooding cycles influencing ecologic processes and patterns. to investigate whether the sugge ... | 2007 | 17387425 |
| using a bayesian method to assign individuals to karyotypic taxa in shrew hybrid zones. | individuals sampled in hybrid zones are usually analysed according to their sampling locality, morphology, behaviour or karyotype. but the increasing availability of genetic information more and more favours its use for individual sorting purposes and numerous assignment methods based on the genetic composition of individuals have been developed. the shrews of the sorex araneus group offer good opportunities to test the genetic assignment on individuals identified by their karyotype. here we exp ... | 2007 | 17431326 |
| genetic diversity and population size: island populations of the common shrew, sorex araneus. | populations of many species are currently being fragmented and reduced by human interactions. these processes will tend to reduce genetic diversity within populations and reduce individual heterozygosities because of genetic drift, inbreeding and reduced migration. conservation biologists need to know the effect of population size on genetic diversity, as this is likely to influence a population's ability to persist. island populations represent an ideal natural experiment with which to study th ... | 2007 | 17498228 |
