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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
[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
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
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
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
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
modelling and monitoring organochlorine and heavy metal accumulation in soils, earthworms, and shrews in rhine-delta floodplains.	in the rhine-delta, accumulation of microcontaminants in floodplain foodwebs has received little attention in comparison with aquatic communities. to investigate organochlorine and metal concentrations in a terrestrial foodchain, samples of soil, earthworms (lumbricus rubellus), and shrew (crocidura russula, sorex araneus) livers and kidneys were taken from two moderately to heavily polluted floodplains. chlorobiphenyl residues in earthworm fat were 0.10 to 3.5 times the concentrations in soil o ...	1995	7794009

(trematoda microphallidae) obtained from the intestine of the shrew crocidura russula (hermann, 1780), definitive host of the fluke present in the estuary of the river llobregat (catalonia, spain). the larval stages are found in two hosts obtained from the area: 1) mercuria confusa (frauenfeld) [= pseudamnicola similis (draparnaud)] (mollusca: hydrobiidae), and 2) gammarus aequicauda (martynov) (crus ...	1993	8215113
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
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
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
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
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

sexual receptivity and oestrus in the white-toothed shrew, crocidura russula monacha.	in common white-toothed shrews, the vaginal smear was an inadequate indicator of receptivity. nucleated epithelial cells usually predominated and most matings took place when the smear was of this type. cornified cells in the smear in infrequent. mating tests showed that virgin females 2 to 4 months old, were unreceptive for extended periods. willingness to mate increased gradually with the age of the female. females were receptive throughout pregnancy, suggesting a continuous secretion of oestr ...	1975	1206646
[comparative macro- and microscopic anatomy of the nasal cavity of european insectivores].	the topography of the nasal fossa and its epithelium were studied in 4 european insectivores, sorex araneus l., crocidura russula (hermann), talpa europaea l. and erinaceus europaeus l. the following results were obtained: 1. the length of the nasal capsules is in relation to the length of the head in all 4 species the same. 2. the noses of all forms studies, except e. europaeus are very similar because of the trunk-shaped pars anterior nasi. 3. the numbers of turbinals are constant. 4. of all t ...	1975	1241682
