| [arbovirus infections in spain: serological survey on small mammals]. | sera of 386 small mammals (rodents, insectivora, small carnivora and cheiroptera) trapped in spain in 1978 and 1979 were studied for antibody against 10 arboviruses. positive reactions were found against flaviviruses: west nile (3.1%), dengue type 2 (0.5%), tick-borne encephalitis, european type (0.2%), together with tahyna (6.5%), uukuniemi (2%) and bhanja (1%) viruses. the animal species concerned by positive reactions were essentially mus spretus and apodemus sylvaticus which were also the mo ... | 1980 | 7460127 |
| [studies of the ecology of some blood protozoa of wild small mammals in north germany (author's transl)]. | in 1977 and 1978, 696 small mammals of 9 different species were surveyed for protozoal blood parasites. the following parasites were found: hepatozoon sylvatici in apodemus flavicollis, h. erhardovae and trypanosoma evotomys in clethrionomys glareolus, t. microti and babesia microti in microtus agrestis and t. croicidurae in crocidura russula. h. erhardovae showed regularly high infection-rates (more than 70%) during all the years in 1977 and 1978. h. sylvatici was found only in 5.6% of the yell ... | 1980 | 6104423 |
| small mammal studies in a sad baiting area. | studies in the laboratory or in the field on the effect of sad virus on small rodents are reported. laboratory experiments by oral inoculation of sad strain in a wide variety of small mammals led to the conclusion that spontaneous sad transmission from rodent to rodent is a rare event. field experiments were conducted by live-trapping, sacrifice and analysis of 192 apodemus sylvaticus, 28 clethrionomys glareolus and 48 crocidura russula. they gave no indication that sad virus became established ... | 1982 | 7128065 |
| quantitative cytoarchitecture of the liver of the shrew crocidura russula (fam. soricidae). ultrastructural and morphometric comparison with rat liver. | the livers of two groups of the shrew crocidura russula, kept under standardized physiological conditions, were investigated with electron microscopy and morphometry. the adaptations to the extremely high basal metabolism of these small mammals are reflected in the architectural characteristics of the hapatocytes, which, in comparison with those of the rat, show a smaller cell volume of the mononuclear hepatocytes (3,800 micrometers3), and increased number of cells per cm3 of liver tissue (250 x ... | 1982 | 7105142 |
| [adiaspiromycosis in small wild mammals caught in tunisia]. | the authors examine the lungs of 125 small mammals caught in different provinces of tunisia and belonging to 12 species; 4 apodemus sylvaticus, 1 mus spretus and 1 crocidura russula possess one adiaspore of emmonsia crescens = chrysosporium parvum or more hundred. they find adiaspiromycosis only in damp biotopes. | 1984 | 6541531 |
| ultrastructural studies on oogenesis in the shrew (crocidura russula): i. the preantral follicle. | ultrastructural analysis of the ovarian follicle prior to antrum formation in the shrew, crocidura russula, shows gradual differentiation of mitochondria, endoplasmic reticulum, golgi complexes, vesicles, and multivescular bodies correlated with the growth of the oocyte from primordial to tertiary follicle and the development of the follicular wall. the growth rate of the follicle in relation to that of the oocyte was found to be biphasic. | 1984 | 6708111 |
| demodex foveolator sp. n. (acari: demodicidae), a new epidermis-dwelling parasite of crocidura suaveolens (pallas, 1821). | a new species, demodex foveolator, is described in all stages of the life cycle from the lesser white-toothed shrew, crocidura suaveolens (pallas, 1821). the species inhabits epidermal pits and apparently is a low-grade pathogen. a suggested trait of structural adaptations of epithelia-dwelling demodicids to their habitats is briefly discussed. | 1984 | 6714845 |
| comparative morphometry of the mitochondria and activity of some enzymes in the myocardium of small mammals. | heart rate in mammals is inversely related to body weight. in the etruscan shrew it exceeds 960 beats/min. since the heart depends primarily on energy from aerobic sources, it was interesting to examine some morphological parameters of the mitochondria in some mammals with a high heart frequency. volume fraction and surface to volume ratio of the mitochondria in the myocardium were determined in the white rat (221 g), white mouse (36 g), white-toothed shrew (8 g) and the etruscan shrew (2 g) usi ... | 1985 | 4020880 |

| ventricular myosin of the shrew crocidura russula, correlation with contractile properties. | the present study demonstrates that in the shrew ventricular muscle the speed of tension development and relaxation, as well as twitch duration, are much shorter than in the guinea-pig. it also shows that ventricular myosin of the shrew has a high ca2+-activated atpase activity and that it is composed of alpha-type heavy chains. namely, the native molecule is a v1 variety of myosin. these findings advance our knowledge on an as yet uncharacterized mammalian heart and further demonstrate the corr ... | 1988 | 2976845 |
| erve virus, a probable member of bunyaviridae family isolated from shrews (crocidura russula) in france. | an apparently new agent, provisionally named erve virus, was isolated in 1982 from tissues of three white toothed shrews, crocidura russula, trapped near saulges village in western france. results of virological and ultrastructural studies suggest that this virus belongs to the bunyaviridae family and is a bunyavirus-like agent. serosurveys indicate that erve virus had apparently a large geographical distribution in france and infects rodents, insectivores, wild boars (sus scrofa), red deer (cer ... | 1989 | 2570514 |
| paradoxical social effects on response to cold during ontogeny of the common white-toothed shrew, crocidura russula. | postnatal development of thermoregulatory responses to cold differs between shrews measured singly or in groups as a litter. single shrews increase their metabolic response to cold within 14 days to maintain normothermia. shrews measured in groups show little or no metabolic response to cold and do not reach normothermia before the 19th day. lower body temperatures in groups are explained by torpor, which obviously needs the prerequisite of forming a group. oxygen consumption of the singly measu ... | 1989 | 2778129 |
| development of temperature regulation in the common white-toothed shrew, crocidura russula. | 1. body temperature and oxygen consumption were measured during the first month of postnatal life in two litters of crocidura russula at four different ambient temperatures. 2. body temperature in the nest varies from 30.5-35.0 degrees c during the first 10 days; afterwards it becomes more constant (35.5-37.0 degrees c). 3. first homoiothermic reactions occur on the 2nd day of life and become effective on the 4th day. 4. in the case of undernourished shrews, torpor is already developed on the 2n ... | 1989 | 2565791 |
| metabolic, respiratory and cardiac activity in the shrew crocidura russula. | oxygen consumption, respiratory rate, heart rate and body temperature of resting common white-toothed shrews (crocidura russula, mean = 11.4 g), have been determined at ambient temperatures (ta) between 0 and 37 degrees c. mean basal oxygen consumption (ta = 30 degrees c, tb = 35.4 degrees c) was 2.3 ml.g-1.h-1 and was about 12% above the value expected on the basis of the allometric relationship applying for mammals. at 0 degree c oxygen consumption was 4.2 times that in the thermal neutral zon ... | 1991 | 1947455 |
| lung and hearth nematodes in some spanish mammals. | thirteen host species belonging to the orders rodentia, insectivora and carnivora from various localities in galicia (nw spain) were examined for heart and lung parasites. the following species were found: parastrongylus dujardini (5.5%) in apodemus sylvaticus, crenosoma striatum in erinaceus europaeus (83%), angiostrongylus vasorum, crenosoma vulpis and eucoleus aerophilus in vulpes vulpes (3, 3.46 and 0.50%, respectively), crenosoma taiga in putorius putorius (100%) and crenosoma sp. in meles ... | 1991 | 1844789 |

| a tendon-locking mechanism in two climbing rodents, muscardinus avellanarius and micromys minutus (mammalia, rodentia). | having compared the microanatomy of the toes of a terrestrial to two climbing species, adaptations were found in the flexor tendons and in the integument. in contrast to crocidura russula, both muscardinus avellanarius and micromys minutus have a tendon-locking mechanism (tlm) that is engaged when the middle phalanx is bent. a ventral thickening of the flexor tendon is situated deep to a thickened portion of the ventral tendon sheath. when twigs or stalks are grasped, the tlm allows less muscula ... | 1996 | 8755339 |
| origin and evolution of homologous repeated sequences in the mitochondrial dna control region of shrews. | the complete mitochondrial dna (mtdna) control region was amplified and directly sequenced in two species of shrew, crocidura russula and sorex araneus (insectivora, mammalia). the general organization is similar to that found in other mammals: a central conserved region surrounded by two more variable domains. however, we have found in shrews the simultaneous presence of arrays of tandem repeats in potential locations where repeats tend to occur separately in other mammalian species. these loca ... | 1996 | 8583904 |
| quadricuspid aortic valve and single coronary artery in a greater white-toothed shrew, crocidura russula. | an adult greater white-toothed shrew (crocidura russula) had both a quadricuspid aortic valve and a single coronary artery arising from the aorta. the shrew was caught on 10 may 1994 in the environs of málaga, southern spain. both congenital anomalies may be potential causes of cardiac dysfunction, but apparently produced no significant cardiac complication in the shrew. this is the first report of a quadricuspid aortic valve in a wild-living mammal. | 1996 | 9359065 |
| female-biased dispersal in the monogamous mammal crocidura russula: evidence from field data and microsatellite patterns. | we investigated dispersal patterns in the monogamous crocidura russula, based both on direct field observations (mark-recapture data) and on genetic analyses (microsatellite loci). natal dispersal was found to be low. most juveniles settled within their natal territory or one immediately adjacent. migration rate was estimated to two individuals per year and per population. the correlation between genetic and geographical distances over a 16 km transect implies that migration occurs over short ra ... | 1997 | 9061966 |
| novel sperm crypts and behavior of gametes in the fallopian tube of the white-toothed shrew, crocidura russula monacha. | the gametes of an insectivore, the white-toothed shrew, crocidura russula monacha, present certain idiosyncratic features not seen in most other eutherian mammals. the spermatozoa display an acrosome of giant proportions, and are produced in relatively small numbers. in trans-illuminated oviducts examined with dic optics, spermatozoa were first sequestered in languid clutches within the isthmus in deep narrow crypts, with some eventually ingested by the crypt epithelium. then, at ovulation (ca. ... | 1997 | 9063000 |
| anatomical study of the abdominal arterial system in soricids (insectivora, mammalia): functional and phylogenetic implications. | information on the anatomy of the abdominal arterial system in insectivora is scarce. we described the origin, distribution, and variations of the visceral abdominal arteries in some soricidae in order to provide the first comprehensive data on this subject in insectivora. results were interpreted from a functional and phylogenetic viewpoint. | 1997 | 9143678 |

| comparison of antihemorrhagic activities in skeletal muscle extracts from various animals against bothrops jararaca snake venom. | antihemorrhagic activities of skeletal muscle extracts from various animals were compared in inhibiting the hemorrhagic activity of bothrops jararaca venom. the muscle extracts of the european hedgehog (erinaceus europaeus) exhibited the strongest activity, followed by those of other insectivores such as the shrew (crocidura russula) and mole (talpa europaea). the antihemorrhagic activities of muscle extracts from experimental animals such as mice, rats, guinea-pigs, hamsters and rabbits were ne ... | 1998 | 9620591 |
| [erve and eyach: two viruses isolated in france, neuropathogenic for man and widely distributed in western europe]. | two arboviruses have been isolated from mayenne, western france, in 1981-1982, during systematic field surveys: eyach virus, a cultivirus from ixodes ricinus and i. ventalloi ticks, and erve virus, a nairovirus from the tissues of white-toothed shrews, crocidura russula. for many years, these two viruses were considered as "orphan viruses" without pathogenic power for man, since it became evident that they circulate actively in europe among populations of wild small and large mammals. moreover, ... | 1998 | 9673063 |
| breeding system and genetic variance in the monogamous, semi-social shrew, crocidura russula. | the population-genetic consequences of monogamy and male philopatry (a rare breeding system in mammals) were investigated using microsatellite markers in the semisocial and anthropophilic shrew crocidura russula. a hierarchical sampling design over a 16-km geographical transect revealed a large genetic diversity (h = 0.813) with significant differentiation among subpopulations (fst= 5-6%), which suggests an exchange of 4.4 migrants per generation. demic effective-size estimates were very high, d ... | 1998 | 28565220 |
| contraction parameters, myosin composition and metabolic enzymes of the skeletal muscles of the etruscan shrew suncus etruscus and of the common european white-toothed shrew crocidura russula (insectivora: soricidae). | in the etruscan shrew, the isometric twitch contraction times of extensor digitorum longus (edl) and soleus muscles are shorter than in any other mammal, allowing these muscles to contract at outstandingly high contraction frequencies. this species has the highest mass-specific metabolic rate of all mammals and requires fast skeletal muscles not only for locomotion but also for effective heat production and for an extremely high ventilation rate. no differences could be detected in the fibre typ ... | 1999 | 10460733 |
| individual reproductive success and effective population size in the greater white-toothed shrew crocidura russula. | in order to investigate the determinants of effective population size in the socially monogamous crocidura russula, the reproductive output of 44 individuals was estimated through genetic assignment methods. the individual variance in breeding success turned out to be surprisingly high, mostly because the males were markedly less monogamous than expected from previous behavioural data. males paired simultaneously with up to four females and polygynous males had significantly more offspring than ... | 2000 | 10821616 |
| the occurrence of cryptosporidium parvum and c. muris in wild rodents and insectivores in spain. | five rodent and two insectivore species were investigated for cryptosporidium at seven sites in north-eastern spain. of the 442 animals studied, 82 apodemus sylvaticus, 1 a. flavicollis, 5 mus spretus, 1 rattus rattus, 8 clethrionomys glareolus and 13 crocidura russula were infected with only c. parvum. eleven a. sylvaticus and 2 c. glareolus were infected with only c. muris and 16 a. sylvaticus, 1 m. spretus and 2 c. glareolus showed mixed infections. both cryptosporidial species were found in ... | 2000 | 10996736 |

| nmr spectroscopy based metabonomic studies on the comparative biochemistry of the kidney and urine of the bank vole (clethrionomys glareolus), wood mouse (apodemus sylvaticus), white toothed shrew (crocidura suaveolens) and the laboratory rat. | the metabolic profiles of three wild mammals that vary in their trophic strategies, the herbivorous bank vole (clethrionomys glareolus), the granivorous wood mouse (apodemus sylvaticus), and the insectivorous white-toothed shrew (crocidura suaveolens), were compared with that of a widely used strain of laboratory rat (sprague dawley). in conjunction with nmr spectroscopic investigations into the urine and blood plasma composition for these mammals, high resolution magic angle spinning (hrmas) 1h ... | 2000 | 11126766 |
| mitochondrial dna variation along an altitudinal gradient in the greater white-toothed shrew, crocidura russula. | the distribution of mitochondrial control region-sequence polymorphism was investigated in 15 populations of crocidura russula along an altitudinal gradient in western switzerland. high-altitude populations are smaller, sparser and appear to undergo frequent bottlenecks. accordingly, they showed a loss of rare haplotypes, but unexpectedly, were less differentiated than lowland populations. furthermore, the major haplotypes segregated significantly with altitude. the results were inconsistent wit ... | 2002 | 11975709 |
| on the development of the shoulder girdle in crocidura russula (soricidae) and other placental mammals: evolutionary and functional aspects. | the development of the shoulder girdle was studied in embryonic stages and a neonate of crocidura russula using histological sections and 3-d reconstructions. neonatal stages of suncus etruscus and mesocricetus auratus, both altricial placentals, were also studied. the earliest stage of c russula, in which the scapula is still partially blastematous, has already a supraspinous fossa. the dorsal portion of the scapular spine does not develop from the anterior margin of the scapula. its mode of de ... | 2002 | 12448772 |
| lipotyphla limb myology comparison. | fore- and hindlimb muscles were dissected in four species of lipotyphla: the western european hedgehog erinaceus europaeus (erinaceidae, erinaceinae); the moonrat echinosorex gymnura (erinaceidae, hylomyinae or galericinae); the tailless tenrec tenrec ecaudatus (tenrecidae, tenrecinae); and the common european white-toothed shrew crocidura russula (soricidae, soricinae). this work completely reviews the limb musculature of these walking mammals. twelve myological characters were evaluated in ord ... | 2002 | 11921044 |
| morphometric geographic variation in the asian lesser white-toothed shrew crocidura shantungensis (mammalia, insectivora) in east asia. | this study investigated geographic variation in the asian lesser white-toothed shrew, crocidura shantungensis miller, 1901, among a number of localities in east asia, including the korean peninsula, tsushima island, cheju island, and taiwan, using univariate and multivariate analyses of cranial morphometric characters. sexual differences were found in taiwanese shrews, but were not evident in those from korea or tsushima. the samples from taiwan had a larger overall cranial size than those from ... | 2003 | 12832832 |
| inbreeding in the greater white-toothed shrew, crocidura russula. | we combined mark-and-recapture studies with genetic techniques of parentage assignment to evaluate the interactions between mating, dispersal, and inbreeding, in a free-ranging population of crocidura russula. we found a pattern of limited and female-biased dispersal, followed by random mating within individual neighborhoods. this results in significant inbreeding at the population level: mating among relatives occurs more often than random, and f(it) analyses reveal significant deficits in hete ... | 2003 | 12703953 |
| taxonomic status and origin of the shrews (soricidae) from the canary islands inferred from a mtdna comparison with the european crocidura species. | european island shrews are either relicts of the endemic pleistocene fauna, e.g.,. crocidura zimmermanni, or were introduced from continental source populations. in order to clarify the taxonomic status and the origin of the two shrew species from the canary islands, a 981bp fragment of cytochrome b gene was investigated in all european crocidura species and compared with the canary shrew (crocidura canariensis) and the osorio shrew (crocidura osorio). the first shares its karyotype with the sic ... | 2003 | 12695091 |
| estimating sex-specific dispersal rates with autosomal markers in hierarchically structured populations. | a recent study suggests that sex-specific dispersal rates can be quantitatively estimated on the basis of sex- and state-specific (pre- vs. postdispersal) f-statistics. in the present paper, we extend this approach to account for the hierarchical structure of natural populations, and we validate it through individual-based simulations. the model is applied to an empirical data set consisting of 536 individuals (males, females, and predispersal juveniles) of greater white-toothed shrews (crocidur ... | 2004 | 15154563 |
| helminth associations in white-toothed shrews crocidura russula (insectivora: soricidae) from the albufera natural park, spain. | the helminths of 218 white-toothed shrews from 29 sites in 2 biotopes in the albufera natural park (valencia, spain) were examined from july 1990 to august 1991. an association analysis of helminths occurring at a prevalence of more than 4% was carried out for 4 species of cestodes located in the intestine (hymenolepis pistillum, h. scalaris, h. tiara, and pseudhymenolepis redonica) and 3 species of nematodes (pseudophysaloptera sp. located in the stomach, stammerinema rhopocephala larvae in the ... | 2004 | 15270101 |
| neotrombicula autumnalis (acari, trombiculidae) as a vector for borrelia burgdorferi sensu lato? | larvae of the trombiculid mite neotrombicula autumnalis were collected at 18 sites in and around bonn, germany, to be screened for infection with borrelia burgdorferi s.l. by means of pcr. questing larvae numbering 1380 were derived from the vegetation and 634 feeding ones were removed from 100 trapped micromammals including voles, mice, shrews and hedgehogs. in a laboratory infection experiment, a further 305 host-seeking larvae from the field were transferred onto borrelia-positive mice and ge ... | 2004 | 15285141 |
| mitochondrial simple sequence repeats and 12s-rrna gene reveal two distinct lineages of crocidura russula (mammalia, soricidae). | a short segment (135 bp) of the control region and a partial sequence (394 bp) of the 12s-rrna gene in the mitochondrial dna of crocidura russula were analyzed in order to test a previous hypothesis regarding the presence of a gene flow disruption in northern africa. this breakpoint would have separated northeast-african c. russula populations from the european (plus the northwest-african) populations. the analysis was carried out on specimens from tunisia (c. r. cf agilis), sardinia (c. r. ichn ... | 2004 | 15162115 |
| hand development and sequence of ossification in the forelimb of the european shrew crocidura russula (soricidae) and comparisons across therian mammals. | hand development in the european shrew crocidura russula is described, based on the examination of a cleared and double-stained ontogenetic series and histological sections of a c. 20-day-old embryo and a neonate. in the embryo all carpal elements are still mesenchymal condensations, and there are three more elements than in the adult stage: the 'lunatum', which fuses with the scaphoid around birth; a centrale, which either fuses with another carpal element or just disappears later in ontogeny; ... | 2004 | 15291793 |
| energy expenditure in crocidurinae shrews (insectivora): is metabolism a key component of the insular syndrome? | a cascade of morphological, ecological, demographical and behavioural changes operates within island communities compared to mainland. we tested whether metabolic rates change on islands. using a closed circuit respirometer, we investigated resting metabolic rate (rmr) of three species of crocidurinae shrews: suncus etruscus, crocidura russula, and c. suaveolens. for the latter, we compared energy expenditure of mainland and island populations. our measurements agree with those previously report ... | 2005 | 16154371 |
| evolutionary history of the greater white-toothed shrew (crocidura russula) inferred from analysis of mtdna, y, and x chromosome markers. | we investigate the evolutionary history of the greater white-toothed shrew across its distribution in northern africa and mainland europe using sex-specific (mtdna and y chromosome) and biparental (x chromosome) markers. all three loci confirm a large divergence between eastern (tunisia and sardinia) and western (morocco and mainland europe) lineages, and application of a molecular clock to mtdna divergence estimates indicates a more ancient separation (2.25 m yr ago) than described by some prev ... | 2005 | 16098767 |
| phylogeographical footprints of the strait of gibraltar and quaternary climatic fluctuations in the western mediterranean: a case study with the greater white-toothed shrew, crocidura russula (mammalia: soricidae). | we used mitochondrial cyt b sequences to investigate the phylogenetic relationships of crocidura russula (sensu lato) populations across the strait of gibraltar, western europe, maghreb, and the mediterranean and atlantic islands. this revealed very low genetic divergence between european and moroccan populations. the application of a molecular clock previously calibrated for shrews suggested that the separation of european from moroccan lineages occurred less than 60 000 bp, which is at least 5 ... | 2005 | 15773942 |
| sex-specific selective pressures on body mass in the greater white-toothed shrew, crocidura russula. | the direction, intensity and shape of viability-, sexual- and fecundity selection on body mass were investigated in a natural population of the greater white-toothed shrew (crocidura russula), combining parentage assignment through molecular techniques and mark-recapture data over several generations. a highly significant stabilizing viability selection was found in both sexes, presumably stemming from the constraints imposed by their insectivorous habits and high metabolic costs. sexual selecti ... | 2005 | 15715835 |
| nonshivering thermogenesis capacity associated to mitochondrial dna haplotypes and gender in the greater white-toothed shrew, crocidura russula. | a selection gradient was recently suggested as one possible cause for a clinal distribution of mitochondrial dna (mtdna) haplotypes along an altitudinal transect in the greater white-toothed shrew, crocidura russula (ehinger et al. 2002). one mtdna haplotype (h1) rare in lowland, became widespread when approaching the altitudinal margin of the distribution. as h1 differs from the main lowland haplotype by several nonsynonymous mutations (including on atp6), and as mitochondria play a crucial rol ... | 2005 | 15660955 |
| pliocene and pleistocene diversification and multiple refugia in a eurasian shrew (crocidura suaveolens group). | we sequenced 998 base pairs (bp) of mitochondrial dna cytochrome b and 799 bp of nuclear gene brca1 in the lesser white-toothed shrew (crocidura suaveolens group) over its geographic range from portugal to japan. the aims of the study were to identify the main clades within the group and respective refugia resulting from pleistocene glaciations. analyses revealed the asian lesser white-toothed shrew (c. shantungensis) as the basal clade, followed by a major branch of c. suaveolens, subdivided se ... | 2006 | 16426868 |
| life cycle and description of a new species of brachylaimid (trematoda: digenea) in spain. | the life cycle of brachylaima llobregatensis n. sp. (trematoda: brachylaimidae) is elucidated. embryonated, operculated, asymmetric eggs (30.9 x 18.2 microm) are eliminated with feces of natural hosts wood mouse mus spretus; white-toothed shrew, crocidura russula; and an experimental host, domestic mouse, mus musculus var. domesticus. the eggs are ingested by the helicid gastropod helix (cornu) aspersa, the only natural and experimental first intermediate host. the miracidium hatches from the eg ... | 2006 | 17304812 |
| shrews as reservoir hosts of borna disease virus. | borna disease virus (bdv) is the causative agent of severe t-cell-mediated meningoencephalitis in horses, sheep, and other animal species in central europe. here we report the first unequivocal detection of a bdv reservoir species, the bicolored white-toothed shrew, crocidura leucodon, in an area in switzerland with endemic borna disease. | 2006 | 16704819 |
| rate of metabolism during lactation in small terrestrial mammals (crocidura russula, mus domesticus and microtus arvalis). | basal rate of metabolism (bmr) and resting maternal rate of metabolism around peak lactation (rmr(l)) were measured in crocidura russula, mus domesticus and microtus arvalis. these species have a moderate or high bmr relative to the scaling relationship of kleiber. one goal of the study was to check whether females of these species show elevated rates of metabolism during lactation. a second goal was to test for a possible intraspecific correlation between the level of bmr and the change in rate ... | 2006 | 16630734 |
| disentangling reasons for low y chromosome variation in the greater white-toothed shrew (crocidura russula). | y chromosome variation is determined by several confounding factors including mutation rate, effective population size, demography, and selection. disentangling these factors is essential to better understand the evolutionary properties of the y chromosome. we analyzed genetic variation on the y chromosome, x chromosome, and mtdna of the greater white-toothed shrew, a species with low variance in male reproductive success and limited sex-biased dispersal, which enables us to control to some exte ... | 2006 | 16582448 |
| comparative fine structure of the epididymal spermatozoa from three korean shrews with considerations on their phylogenetic relationships. | this study examined the fine structures of epididymal spermatozoa on the lesser white-toothed shrew (crocidura suaveolens), the japanese white-toothed shrew (c. dsinezumi) and the big white-toothed shrew (c. lasiura) belonging to the subfamily crocidurinae living in korea. in the spermatozoa of c. suaveolens, the head has a large acrosome, a smooth inner acrosomal membrane and a wavy, finger-like, electron-dense apical body. the neck has a solid proximal centriole that is filled with electron-de ... | 2006 | 16972552 |
| mediterranean populations of the lesser white-toothed shrew (crocidura suaveolens group): an unexpected puzzle of pleistocene survivors and prehistoric introductions. | an earlier study revealed the strong phylogeographical structure of the lesser white-toothed shrew (crocidura suaveolens group) within the northern palaearctic. here, we aim to reconstruct the colonization history of mediterranean islands and to clarify the biogeography and phylogeographical relationships of the poorly documented middle east region with the northern palaearctic. we performed analyses on 998-bp-long haplotypes of the mitochondrial cytochrome b gene of 143 samples collected around ... | 2007 | 17688544 |
| bioaccumulation of metals and effects of landfill pollution in small mammals. part i. the greater white-toothed shrew, crocidura russula. | here we quantified the bioaccumulation of metals (lead, mercury, cadmium, iron, magnesium, zinc, copper, manganese, molybdenum, and chromium) and assessed several morphological (ri, relative weights) and genotoxic parameters as biomarkers of pollution from the landfill of garraf (barcelona, ne spain). specimens of crocidura russula (insectivora, mammalia) from the landfill site showed increased pb, cd, mg, zn, cu, and cr concentrations in their tissues. levels of mercury were below detection lim ... | 2007 | 17367842 |
| how does the greater white-toothed shrew, crocidura russula, responds to long-term heavy metal contamination? -- a case study. | heavy metals accumulation in parallel with the evaluation of physiological and biochemical effects resulting from continued metal exposure were considered here using for the first time the great white-toothed shrew crocidura russula as an in vivo model. shrews were originated from an abandoned lead/zinc mining area and from a reference area, both in alentejo, southern portugal. hepatic contents of nickel, copper, zinc, cadmium, mercury and lead were quantified by inductively coupled plasma mass ... | 2007 | 17321569 |
| a novel set of microsatellite marker loci linkage-mapped in the house musk shrew, suncus murinus. | ten microsatellite dna loci developed for the white-toothed shrew (crocidura russula) were tested for pcr amplification and for utility in linkage studies in the house musk shrew, suncus murinus. four primer pairs successfully yielded pcr amplicons and showed polymorphism between two mutant strains, ban-kc,oeb and wz. cloning and sequencing of the pcr amplicons of all the four loci confirmed the presence of microsatellite sequences. alleles segregating in an f2 resource population constructed fr ... | 2007 | 17283891 |
| 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 |
| metal bioaccumulation in the greater white-toothed shrew, crocidura russula, inhabiting an abandoned pyrite mine site. | hepatic and renal concentrations of iron, magnesium, zinc, lead, copper, manganese, mercury, cadmium, molybdenum, chromium, and nickel were quantified in shrews (crocidura russula) inhabiting a pyrite mine site in portugal. several morphological parameters (body weight, residual index, and relative weights) were also examined to clarify the physiological effects of pollution. shrews from the mine showed increased bioavailability of fe, pb, hg, cd, mo, and ni in comparison with reference specimen ... | 2007 | 17107703 |
| 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 |
| [localization of larvae of neotrombicula (n) monticola (trombiculidae) ticks on the vertebrates]. | the specific features of distribution of neotrombicula (n) monticola schluger et davidov, 1967 on small mammals were studied in the tien shan montains (kirghiz ridge). n. (n ) monticola was found to occur in all the places under study. nine species of mammals (pigmy white-toothed shrew, dwarf hamster, tamarisk gerbil, turkestan rat, long-tailed mouse, tien shan, kirghiz, and silver voles, and wood mouse) were established to be feeders of larvae of the ticks. n. (n) monticola larvae were detected ... | 2007 | 17912838 |
| the electrocardiogram of european shrews. | a recording method of electrocardiograms in resting animals is described. the electrocardiograms of crocidura russula, crocidura leucodon, crocidura suaveolens, neomys fodiens and sorex araneus are similar to those of other small mammals. t-wave directly follows the qrs-complex. the duration of electrocardiograms depends on heart mass and body temperature. heart rate shows no influence on the duration of electrocardiograms. | 2007 | 2870871 |
| bioaccumulation of lead, mercury, and cadmium in the greater white-toothed shrew, crocidura russula, from the ebro delta (ne spain): sex- and age-dependent variation. | we quantified bioaccumulation of lead, mercury, and cadmium in bones from 105 greater white-toothed shrews (crocidura russula) collected at the ebro delta, a polluted area, and the medas islands, a control site. lead and mercury levels varied with site, age, and sex, although statistical significances depended on each factor. globally, shrews from the polluted area exhibited significantly higher concentrations of pb and hg. increment of pb with age was particularly remarkable in wetland animals ... | 2007 | 16777291 |
| tissue, age, and sex distribution of thallium in shrews from doñana, a protected area in sw spain. | in 1998, the protected area of doñana, an important natural region in sw europe, was affected with great amount of acidic waters and sludge from a pyrite mine loaded with toxic metals such as thallium (tl). since this ecological catastrophe, several studies have addressed the effects of this pollution on the flora and fauna in this protected area. however, in contrast to other non-essential metals, scarce information on tl was available after this disaster, especially in terrestrial environments ... | 2007 | 17570462 |
| 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 |
| 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 |
| evaluation of some sources of variability in using small mammals as pollution biomonitors. | in the present study the effects of gender, age and nutritional status on tissue concentrations of some trace elements (zn, cu, mn, and cr) in wood mouse (apodemus sylvaticus), spanish shrew (sorex granarius), and great white-toothed shrew (crocidura russula) were investigated. four sampling stations were selected for the study: a restored mine dump, an area characterised by ultrabasic soil and two sites in oak woods in the vicinity of a power plant. gender had no effect on the tissue concentrat ... | 2008 | 18313721 |

| the role of rodents and shrews in the transmission of toxoplasma gondii to pigs. | inadequate rodent control is considered to play a role in toxoplasma gondii infection of pigs. this issue was addressed in the current study by combining a 4-month rodent control campaign and a 7-month longitudinal analysis of t. gondii seroprevalence in slaughter pigs. three organic pig farms with known rodent infestation were included in the study. on these farms, presence of t. gondii in trapped rodents was evaluated by real-time pcr. all rodent species and shrews investigated had t. gondii d ... | 2008 | 18606498 |
| lawsonia intracellularis in rodents from pig farms with the occurrence of porcine proliferative enteropathy. | lawsonia intracellularis is an obligate intracellular bacterium causing proliferative enteropathy in certain species of domestic, laboratory and captive animals. the aim of our study was to detect l. intracellularis in free-living rodents from pig farms in the czech republic. | 2008 | 18673433 |
| haematology, genotoxicity, enzymatic activity and histopathology as biomarkers of metal pollution in the shrew crocidura russula. | haematological (wbc, rbc, hgb and hct) and genotoxicity (mnt) parameters, hepatic enzymatic activities (gst, gpx and gr), and a histopathological evaluation of liver, kidneys and gonads were assessed as general biomarkers of metal pollution in the shrew crocidura russula inhabiting a pyrite mining area. specimens exposed to metals presented a few significant alterations when compared with reference animals: gst activity decreased; micronuclei increased; and evident liver alterations related to m ... | 2008 | 18448220 |
| 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 |
| histological description of seminiferous epithelium and cycle length of spermatogenesis in the water shrew neomys fodiens (mammalia: soricidae). | recently, we examined the spermatogenesis cycle length in two shrews species, sorex araneus characterized by a very high metabolic rate and a polyandric mating system (sperm competition) resulting in a short cycle and crocidura russula characterized by a much lower metabolic rate and a monogamous mating system showing a longer cycle. in this study, we investigated the spermatogenesis cycle in neomys fodiens showing an intermediate metabolic rate. we described the stages of seminiferous epitheliu ... | 2008 | 17629637 |
| habitat-quality effects on metapopulation dynamics in greater white-toothed shrews, crocidura russula. | the effects of patch size and isolation on metapopulation dynamics have received wide empirical support and theoretical formalization. by contrast, the effects of patch quality seem largely underinvestigated, partly due to technical difficulties in properly assessing quality. here we combine habitat-quality modeling with four years of demographic monitoring in a metapopulation of greater white-toothed shrews (crocidura russula) to investigate the role of patch quality on metapopulation processes ... | 2008 | 18959315 |
| the timing of the shrew: continuous melatonin treatment maintains youthful rhythmic activity in aging crocidura russula. | laboratory conditions nullify the extrinsic factors that determine the wild expected lifespan and release the intrinsic or potential lifespan. thus, wild animals reared in a laboratory often show an increased lifespan, and consequently an increased senescence phase. senescence is associated with a broad suite of physiological changes, including a decreased responsiveness of the circadian system. the time-keeping hormone melatonin, an important chemical player in this system, is suspected to have ... | 2009 | 19526053 |
| kestrel-prey dynamic in a mediterranean region: the effect of generalist predation and climatic factors. | most hypotheses on population limitation of small mammals and their predators come from studies carried out in northern latitudes, mainly in boreal ecosystems. in such regions, many predators specialize on voles and predator-prey systems are simpler compared to southern ecosystems where predator communities are made up mostly of generalists and predator-prey systems are more complex. determining food limitation in generalist predators is difficult due to their capacity to switch to alternative p ... | 2009 | 19234618 |
| inferring recent migration rates from individual genotypes. | we present a novel and straightforward method for estimating recent migration rates between discrete populations using multilocus genotype data. the approach builds upon a two-step sampling design, where individual genotypes are sampled before and after dispersal. we develop a model that estimates all pairwise backwards migration rates (m(ij), the probability that an individual sampled in population i is a migrant from population j) between a set of populations. the method is validated with simu ... | 2009 | 19222755 |
| characterization of imjin virus, a newly isolated hantavirus from the ussuri white-toothed shrew (crocidura lasiura). | until recently, the single known exception to the rodent-hantavirus association was thottapalayam virus (tpmv), a long-unclassified virus isolated from the asian house shrew (suncus murinus). robust gene amplification techniques have now uncovered several genetically distinct hantaviruses from shrews in widely separated geographic regions. here, we report the characterization of a newly identified hantavirus, designated imjin virus (mjnv), isolated from the lung tissues of ussuri white-toothed s ... | 2009 | 19357167 |
| 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 |
