| a wild common shrew (sorex araneus) with an xxy sex chromosome constitution. | an adult male common shrew with an xxy sex chromosome constitution was found in a natural population. the external appearance of the animal and size of the accessory glands were normal but the testes were as small as those of immature shrews. histological preparations of the testis revealed seminiferous tubules containing only one type of cell, probably sertoli cells, and interstitial cell hyperplasia. | 1984 | 6694150 |
| nondisjunction frequencies in robertsonian heterozygotes from natural populations of the common shrew, sorex araneus l. | pregnant female common shrews were collected from an area of robertsonian polymorphism, involving five different arm combinations, around oxford (england). the females and their fetuses were karyotyped, and the karyotypes of the sires were deduced. ten pregnancies where at least one parent was known to be either a single or double robertsonian heterozygote were available for analysis. from these pregnancies, upper and lower estimates of anaphase i nondisjunction arising from robertsonian heteroz ... | 1984 | 6510020 |
| breeding the common shrew (sorex araneus) in captivity. | a method for the systematic breeding of the common shrew (sorex araneus) is described. by use of this method 20 litters of common shrew, conceived in the wild and in captivity, were reared to weaning. successful fertilization was recorded for 74% of pairings and 68% of young known to have been born were reared to weaning. breeding records indicate that common shrews will mate within a few days of pairing and that the duration of pregnancy and lactation is about 43 days. | 1984 | 6513501 |
| production efficiency in small mammal populations. | the data used to analyse the relationship between production (p) and respiration (r) in small mammals (grodziński and french 1983) are reanalysed and different conclusions are drawn. differences in production efficiency cannot be attributed to any particular trophic classe, but in the higher taxonomic categories the murids have higher production effeciency than the rest. however examination of numerous populations of the same species shows that production efficiencies of congeneric species somet ... | 1984 | 28310743 |
| light and electron microscopical observations on the male excurrent duct system of the common shrew (sorex araneus). | in sexually active common shrews (sorex araneus) the rete testis is a simple sac-like structure situated superficially between the equator and the anterior pole of the testis, and its epithelium glycogen-rich cells. in the ductuli efferentes, the tight junctions of the epithelial cells are poorly developed. the epididymis can be divided cytologically into initial, middle and terminal segments, and some variations are apparent in the fine structure of the principal cells throughout the duct. in t ... | 1984 | 6699809 |
| isoenzyme variation in the common shrew (sorex araneus) in britain, in relation to karyotype. | samples of common shrews with an aberdeen race, oxford race and hermitage race karyotype and from the oxford-hermitage hybrid zone were screened for genotype at six polymorphic enzyme loci. the common allele at all loci was the same in all samples suggesting that the degree of genic divergence between the karyotypic races is not great. however, shrews of the aberdeen race appear to be somewhat distinct. there were differences in allele frequencies, range of alleles and heterozygosities at the mp ... | 1985 | 2932412 |
| meiotic studies of robertsonian heterozygotes from natural populations of the common shrew, sorex araneus l. | adult male common shrews, both robertsonian heterozygotes and homozygotes, were collected from oxford and elsewhere in britain. in both simple robertsonian heterozygotes and robertsonian heterozygotes with monobrachial homology, regular chain configurations were observed at meiosis i; only 1-2% were incomplete such that univalents were observed. on the average, there was one chiasma per chromosome arm among those that displayed robertsonian variation, including both chain configurations and biva ... | 1986 | 3956265 |
| karyotypic races of the common shrew (sorex araneus l.) from northern poland. | karyotypic races of the common shrew which differed with respect to the combinations of chromosome arms in certain 2-armed autosomes were distinguished in poland. two eastern races with the arm combination ik, and one western race with the arm combination hi in the third pair of autosomes were established. in the contact area of these chromosomal forms, the fourth karyotypic race with the arm combination hk was found. | 1986 | 3743724 |
| 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 |
| the xyy condition in a wild mammal: an xy/xyy mosaic common shrew (sorex araneus). | xy/xyy sex-chromosome mosaicism was demonstrated in both bone marrow and germ cells of a wild adult common shrew. secondary sexual characteristics were those of a normal male, but the testes were small, and the sperm count was only about 3% of normal. most of the seminiferous tubule cross-sections examined revealed serious spermatogenic impairment and a reduced diameter. a range of sex-chromosome pairing configurations was observed in xyy primary spermatocytes, including configurations involving ... | 1986 | 3709237 |
| factors responsible for a karyotypic polymorphism in the common shrew, sorex araneus. | a robertsonian karyotypic polymorphism in the common shrew in the oxford area, first described in the 1950s, was re-examined. the polymorphism involves chromosome arm combinations kq, no and pr (characteristic of the oxford karyotypic race), ko (characteristic of the hermitage karyotypic race) and jl (found in both races). the polymorphism for jl was sporadic along a north-south transect through the oxford area, with the frequency of the twin-acrocentric morph never exceeding 10%. the frequency ... | 1986 | 2881304 |

| fluoride in the prey of barn owls (tyto alba). | bone fluoride in short-tailed voles (microtus agrestis) and common shrews (sorex araneus), the prey of barn owls (tyto alba), was studied on anglesey, north wales. the average fluoride content of m. agrestis skulls obtained from a location 0.9 km from an aluminium reduction plant was significantly greater than that of skulls from another location 22 km from the source of industrial fluoride pollution. at both locations, mean fluoride levels of skulls extracted from owl pellets and those of voles ... | 1987 | 15092770 |
| the chromosome complement of sorex granarius--the ancestral karyotype of the common shrew (sorex araneus)? | we present the g-band karyotype of sorex granarius (miller, 1910). with minor exceptions, each of the acrocentric autosomes in this karyotype is completely homologous to one of the chromosome arms in the karyotype of the common shrew (sorex araneus l., 1758). if, as is the simplest interpretation, the karyotypic evolution in s. araneus is by repeated robertsonian fusion, the karyotype in s. granarius represents the ancestral condition. we urge breeding studies to establish whether the designatio ... | 1988 | 3198417 |
| spermatogenesis in heterozygotes for robertsonian chromosomal rearrangements from natural populations of the common shrew, sorex araneus. | twenty-two adult male common shrews were collected from 5 sites in the vicinity of oxford (uk) close to the zone of hybridization between two karyotypic races. the shrews were subdivided into 3 karyotypic categories: homozygotes, simple robertsonian heterozygotes (which form one or more trivalents at prophase i of meiosis) and complex robertsonian heterozygotes (which form a quadrivalent). the ratio of primary spermatocytes to round spermatids was determined from transverse sections of seminifer ... | 1989 | 2600900 |

| ontogeny of relationship of middle ear and temporomandibular (squamomandibular) joint in mammals. ii. morphology and ontogeny in insectivores. | the ontogeny of the mandibular joint and the middle ear region was studied in erinaceus europaeus, sorex araneus, talpa europaea and elephantulus rozeti. during development, a passage connection was found between the mandibular condyle and meckel's cartilage that is produced by the primordium of the lateral pterygoid muscle. the articular disk is formed apart and it appears later in development. | 1989 | 2718717 |
| distribution of trace element pollutants in a contaminated grassland ecosystem established on metalliferous fluorspar tailings. 1: lead. | concentrations of lead in vegetation, invertebrates and small mammals in a grassland ecosystem evolved from a mine waste revegetation scheme indicated the high concentration of lead in the original tailings. lead levels in invertebrates reflected dietary concentrations and feeding strategy, a pattern also true of the indigenous small mammals. total body and tissue concentrations of lead in the herbivorous microtus agrestis l. (field vole) and insectivorous sorex araneus l. (common shrew) were si ... | 1989 | 15092440 |
| distribution of trace element pollutants in a contaminated grassland ecosystem established on metalliferous fluorspar tailings. 2: zinc. | concentrations of zinc in vegetation, invertebrates and small mammals in a grassland ecosystem derived from a mine waste vegetation scheme indicated the high concentration of zinc in the original tailings. however, the considerable differences in soil and vegetation zinc concentrations between the tailings and an uncontaminated site were not reflected in the invertebrate and small mammal communities. invertebrate zinc levels and total body concentrations in microtus agrestis l. (field vole) and ... | 1989 | 15092405 |
| distribution of trace element pollutants in a contaminated ecosystem established on metalliferous fluorspar tailings. 3: fluoride. | high total soil fluoride (10 000 microg g(-1)) in the metalliferous fluorspar tailings was reflected by elevated concentrations in standing live vegetation (300-1000 microg g(-1)); plant roots (c. 6000 microg g(-1)); plant litter (c. 4000 microg g(-1)); total body concentrations of invertebrates (400-4000 microg g(-1)) and the small mammals microtus agrestis (120-360 microg g(-1)) and sorex araneus (140-250 microg g(-1)). seasonal changes in the standing live vegetation and the availability of s ... | 1989 | 15092395 |
| basic functional properties of the cardiac muscle of the common shrew (sorex araneus) and some other small mammals. | the resting heartbeat frequency of all the studied wild small mammals (body mass 3-20 g) was lower than that predicted by the allometric equation for a typical mammal. the heart rate of the laboratory mouse was a little higher than the expected value. the ventricular mass of the small wild mammals was higher than predicted for their size, but that of the laboratory mouse was below the expected value. thus, adequate cardiac output in the wild small mammals is achieved by compensating the low hear ... | 1989 | 2809495 |
| nucleus limitans thalami--comparative anatomical study. | cyto- and myeloarchitectonics as well as acetylcholinesterase activity of the nucleus limitans thalami--an important part of the nociceptive system--were studied in insectivora (sorex araneus, erinaceus europaeus, talpa europaeus), rat, rabbit, cat, monkey and man. our results suggest that nucleus limitans is phylogenetically a rather new structure. in insectivora and in the rat we could not find any evident group of neurons resembling nucleus limitans. in the rabbit and cat nucleus limitans is ... | 1989 | 2511740 |
| longitudinal study of natural foci of central european encephalitis virus in west slovakia. | a total of 2922 small terrestrial mammals of 12 species were collected in six localities of west slovakia between 1981 and 1986. when examined for the prevalence of neutralizing antibodies (na) to central european encephalitis (cee) virus we found that 14.6% had antibody. nearly all (97%) of the 426 animals with antibody were clethrionomys glareolus, the most abundant species (52.6% of mammals collected, 15.1% of those with antibody). apodemus flavicollis (22.5% of mammals collected, 18.1% of th ... | 1990 | 1983180 |
| relation of the insular claustrum to the neocortex in insectivora. | the claustra of 9 species of insectivora (sorex araneus, sorex minutus, tenrec ecaudatus, solenodon paradoxus, neomys fodiens, erinaceus europaeus, talpa europaea, desmana moschata, potamogale velox) were investigated. in all examined animals we found two parts of the insular claustrum: the main part called by us the pars principalis and more medially situated lamina profunda claustri. in the "basal" insectivora the main part is in close contact with the layer via of the neocortex. in some more ... | 1990 | 1707077 |
| 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 |
| [small mammals at community refuse dumps as reservoirs of pathogens and parasites]. | five-year studies (1981-1986) were performed to investigate a total number of 2589 small mammals of 18 species. refuse dumps are marked for highly specific conditions. the difference between refuse dumps and natural habitats consists in more sufficient quantity of food, better sheltering possibilities and in highly specific microclimate particularly. as a result of aerobic and anaerobic decompositions of organic materials, temperature in dumps is approximately 50 degrees c. from ecological point ... | 1991 | 1807042 |
| the occurrence of centrorhynchus (acanthocephala) in shrews (sorex araneus and sorex minutus) in the united kingdom. | encysted acanthocephalans belonging to the genus centrorhynchus were found in the body cavities of sorex araneus (common shrew) and sorex minutus (pygmy shrew) from boxworth, cambridgeshire, u.k. fifty percent of the male s. araneus and 67% of the male s. minutus examined were found to be infected, with the mean intensity (+/-sd) being 54.3 +/- 91.3 and 14.7 +/- 18.4, respectively. the species of centrorhynchus in the shrews may be centrorhynchus aluconis, which is distributed widely in tawny ow ... | 1991 | 2040960 |
| hazardous exposure of ground-living small mammals to cadmium and lead in contaminated terrestrial ecosystems. | the dietary exposure to cadmium and lead of two ground-living species of small mammals, i.e., shrews sorex araneus (insectivora) and voles microtus agrestis (rodentia), was investigated and related to metal loads in target organs (kidneys and liver). the study was done in two natural areas polluted with cadmium and lead originating from urban and industrial metal sources. the average intake of cadmium by the herbivorous voles varied between 0.1 and 0.4 micrograms/g/day and of lead between 2 and ... | 1991 | 2015002 |
| genetic differentiation of polish populations of sorex araneus l. iii. interchromosomal recombination in a hybrid zone. | two parapatric chromosomal races of the common shrew (sorex araneus) in poland differ in their complement of metacentric arm combinations: hk, io, gr, nm (race iv), and hi, ko, gm, np (race ii). in hybrids, these eight race-diagnostic metacentrics form two randomly segregating complexes. the first complex (c1) occurs in the form of a ring configuration ok/kh/hi/io, or a chain o/ok/kh/hi/i (when there is robertsonian polymorphism of the element io). the second complex (c2) always takes the form o ... | 1991 | 28563830 |
| multiple paternity in wild common shrews (sorex araneus) is confirmed by dna-fingerprinting. | we have tested for the occurrence of multiple paternity in wild common shrews by karyotypic analysis and dna-fingerprinting of five wild-caught females and their litters. karyotypic data suggest that some litters were sired by more than one male, but provide no definitive evidence. by using dna-fingerprinting, it was possible to establish that two males sired the litter of two females. the present report shows that multiple paternity is not a rare phenomenon in the common shrew and by using dna- ... | 1991 | 1880048 |
| synaptonemal complexes of the common shrew, sorex araneus l., in spermatocyte spreads. | this paper presents an electron microscopic analysis of the behavior and morphology of the sex chromosomes and autosomes during prophase i in the common shrew, sorex araneus l. the pairing patterns of the x/y1y2 and autosomal robertsonian trivalents are described. | 1991 | 2004560 |
| trace metal accumulation by the shrew sorex araneus. i. total body burden, growth, and mortality. | a laboratory feeding trial is described in which a known trace metal accumulator, the shrew sorex araneus, was presented with an artificial diet containing high levels of copper and cadmium. methodological difficulties relating to feeding trials on first generation offspring of insectivorous small mammals caught in the wild are described. there was no relationship between copper or cadmium intake and mortality during the trials. sex differences in growth were apparently not influenced by metal i ... | 1992 | 1385072 |
| male common shrews (sorex araneus) with long meiotic chain configurations can be fertile: implications for chromosomal models of speciation. | two chromosomal races of common shrews (sorex araneus) were crossed in captivity to generate chain vii-forming complex robertsonian heterozygotes. meiosis and gametogenesis were studied in three male hybrids. regular chain vii configurations were observed at both pachytene and diakinesis/metaphase i, although in many pachytene spreads the chain configuration was incomplete (the basis of this peculiarity is unknown). from metaphase ii counts, the frequency of anaphase i nondisjunction in the comp ... | 1992 | 1582263 |
| a model of a hybrid zone between two chromosomal races of the common shrew (sorex araneus). | the common shrew (sorex araneus) is subdivided into several karyotypic races in britain. two of these races meet near oxford o form the "oxford-hermitage" hybrid zone. we present a model which describes this system a; a "tension zone," i.e., a set of clines maintained by a balance between dispersal and selection against chromosomal heterozygotes. the oxford and hermitage races differ by robertsonian fusions with monobrachial homology (kq, no versus ko), and so fl hybrids between them would have ... | 1992 | 28564402 |
| trace metal accumulation by the shrew sorex araneus. ii. tissue distribution in kidney and liver. | the distributions of trace metals in tissues of shrews in a series of feeding trials are described. the relationship between body cadmium burden and organ weight was directly related to differences in body weight. organ weight expressed as a percentage of body weight was constant in the kidney, but was correlated with cadmium burden for the liver. liver and kidney accounted for up to 80% of total body cadmium. the proportion of the body cadmium burden found in the kidney ranged from 8 to 17%. co ... | 1992 | 1385073 |
| venomous mammals. | it is not widely appreciated that mammals can be venomous in the manner of snakes and lizards. however, it was first demonstrated scientifically 50 years ago in the case of the american short-tailed shrew. subsequently, similar evidence has been obtained from european shrews and the haitian solenodon, but research in this area has been almost completely neglected for the last 20 years. in complete contrast to what has been learned about other animal venoms, the identity and mode of action of mam ... | 1992 | 1641406 |
| maximum heart rate of soricine shrews: correlation with contractile properties and myosin composition. | maximum heart rates (hr) of three soricine shrews and six other small mammals were measured in response to a single supramaximal dose of isoproterenol (iso) under urethan anesthesia. the highest hr, 1,043 +/- 66 (sd) beats/min (n = 3), was in least shrew (sorex minutus, mean body mass 3.02 +/- 0.81 g). maximum hrs of common shrew (sorex araneus, 7.16 +/- 1.54 g) and water shrew (neomys fodiens, 12.80 +/- 1.54 g) were 938 +/- 29 (n = 7) and 887 +/- 21 (n = 6), respectively. in general, maximum hr ... | 1992 | 1534206 |
| cryptosporidiosis in poland: clinical, epidemiologic and parasitologic aspects. | stool samples from 692 children hospitalized with symptoms of gastroenteritis, were examined for cryptosporidium parvum. the oocysts were found in 17 (2.4%) children. there was no association with age, sex or location of household. however, relatively higher rate of oocyst exclusion was found among 2-month- to 3-year-old groups (50%) and among children from villages (43%). six children from the group of infected were additionally screened for general immunocompetence. four of these exhibited sig ... | 1993 | 8013931 |
| borrelia burgdorferi in a focus of lyme borreliosis: epizootiologic contribution of small mammals. | the contribution of woodmice (apodemus sylvaticus), yellow-necked mice (apodemus flavicollis) and bank voles (clethrionomys glareolus) was compared in a focus of lyme borreliosis in switzerland during a 7 months' study. all three species of mice and one species of shrews (sorex araneus) were shown parasitized by infected ixodes ricinus immatures. about 14% of larvae and 50% of nymphs collected on small mammals were infected with b. burgdorferi. spirochetes were isolated from blood of 3 woodmice ... | 1993 | 8325567 |
| study of a contact between two chromosomally monomorphic races of sorex araneus l. (common shrew). | one hundred and twelve specimens of the common shrew from 21 populations in ne poland were studied from an area of contact between chromosomal race ii (metacentric chromosomes: hi, ko, gm, np) and race vii (ki, hn, gr, mp). no direct contact was found between the races in the study area; there were no mixed or hybrid populations. the shortest distance between populations of the two races was 1.2-1.6 km. possible explanations for this pattern of the races' disjunction are discussed. | 1993 | 8407355 |
| vector and host relationships of california serogroup viruses in western siberia. | during 1990 and 1991, adult mosquitoes were collected along the ob river and its tributaries in western siberia from approximately 51 degrees 18'n to 66 degrees 4'n. fifteen virus strains were isolated from 74,196 mosquitoes tested in 1,874 pools. these included tahyna virus from aedes cataphylla-punctor subgroup (one) and ae. excrucians (one), and inkoo (ink) virus from ae. communis (one), ae. communis subgroup (one), ae. hexodontus (two), ae. punctor subgroup (two), ae. punctor complex (one), ... | 1993 | 8352392 |
| centrorhynchus aluconis (acanthocephala) and other helminth species in tawny owls (strix aluco) in great britain. | observations on the distribution of centrorhynchus aluconis (acanthocephala) and 6 other species of helminths in the definitive host strix aluco, in tawny owl, are presented. infected owls were collected from 16 sites ranging from tarbet, strathclyde, scotland, to ewhurst, surrey, in the south of england. in addition, unidentified cyclophyllidean cestodes were found in the alimentary tract of the tawny owls. centrorhynchus aluconis was the most prevalent helminth found and had the highest intens ... | 1993 | 8277390 |
| maintenance by hares of european borrelia burgdorferi in ecosystems without rodents. | during may-october 1991 shrews (sorex spp.), small rodents (apodemus spp., clethrionomys glareolus [schreber]), and hares (lepus spp.) were sampled near stockholm, sweden. nymphal ixodes ricinus (l.) derived from blood-engorged larvae collected from these mammals were investigated by phase-contrast microscopy and immunofluorescence assay (ifa) using the monoclonal antibody h6831 directed against the ospb protein of borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner. three rodent s ... | 1993 | 8433337 |
| pneumocystis carinii and helminth parasitism in shrews sorex araneus and sorex caecutiens. | the prevalence of pneumocystis carinii was compared in two species of shrews, sorex araneus and sorex caecutiens in finnish lapland. the overall prevalence of p. carinii in s. araneus was 70% and in s. caecutiens was 17%. the prevalence for s. araneus is the highest reported for wild animals. the interspecific differences in prevalence were significant for all sex and age groups except for adult males. based on multiway contingency tables (log-linear models), there was no dependence between sex ... | 1993 | 8487377 |
| diet selection by common shrews sorex araneus in a depleting environment. | common shrews (sorex araneus l.) were presented with two prey types at various densities in a depleting environment. observed diet choice was compared to predictions of the classical optimal diet model and of "shrew-specific" simulations incorporating patch depletion. two strategies were simulated: expansion of the diet from taking only profitable prey to taking both types, and fixed partial preference. the simulations predict partial preference over a narrow range of initial densities of profit ... | 1993 | 24897697 |
| the x-autosome translocation in the common shrew (sorex araneus l.): late replication in female somatic cells and pairing in male meiosis. | common shrews have an xx/xy1y2 sex chromosome system, with the "x" chromosome being a translocation (tandem fusion) between the "original" x and an autosome; in males this autosome is represented by the y2 chromosome. from g-banded chromosomes, the y2 is homologous to the long arm and centromeric part of the short arm of the x. the region of the x that is homologous to the y2 and also the telomeric region of the short arm of the x were found to be early replicating in somatic cells from a female ... | 1993 | 8325167 |
| a risk-assessment model for toxic exposure of small mammalian carnivores to cadmium in contaminated natural environments. | a model is presented to assess the risk of cadmium toxicity in mammalian wildlife in contaminated environments. the target-organ load was used as a hazard indicator and animals were considered to be at risk when a critical value, i.e. the lowest-observed-adverse-effect level (loael), was attained or exceeded. the model was developed for sorex araneus, a small mammalian predator with a high potential of attaining the critical target-organ load. model parameter values were estimated from both expl ... | 1993 | 8108718 |
| experimental accumulation of lead from soil through earthworms to common shrews. | common shrews (sorex araneus) were fed on earthworms containing high concentrations of lead. both the earthworms and shrews originated from uncontaminated areas, but earthworms for the "lead" group of shrews were reared in the laboratory for 3 or 4 weeks in highly pb-polluted soil from near an old lead smelter. the control group of shrews received the same amount of earthworms from the uncontaminated area. the acceptance of the experimental food by shrews was significantly lower in the lead grou ... | 1994 | 7804726 |
| the morphology of hymenolepidid and dilepidid cestodes from common and pygmy shrews (soricidae) in southeast england. | one hundred and six of 109 common shrews (sorex araneus) and 62 of 72 pygmy shrews (s. minutus), obtained by longworth trapping in southeast england, were infected with cestodes. ten species were recovered: choanotaenia hepatica and hymenolepis prolifer (found in s. araneus); choanotaenia crassiscolex, hymenolepis furcata, h. jacutensis, h. schaldybini, h. scutigera, h. singularis, h. diaphana and h. infirma (in both hosts). the morphology, taxonomy and ecology of these species are discussed and ... | 1994 | 7829846 |
| chromosomal versus mitochondrial dna evolution: tracking the evolutionary history of the southwestern european populations of the sorex araneus group (mammalia, insectivora). | the shrews of the sorex araneus group have undergone a spectacular chromosome evolution. the karyotype of sorex granarius is generally considered ancestral to those of sorex coronatus and s. araneus. however, a sequence of 777 base pairs of the cytochrome b gene of the mitochondrial dna (mtdna) produces a quite different picture: s. granarius is closely related to the populations of s. araneus from the pyrenees and from the northwestern alps, whereas s. coronatus and s. araneus from italy and th ... | 1994 | 28568274 |
| distribution patterns and microhabitat segregation in gastrointestinal helminths of sorex shrews. | we studied the distribution patterns and microhabitat use in gastrointestinal helminths of the shrews sorex araneus and s. caecutiens in finland. the distribution of species prevalences was bimodal, and in s. araneus the abundance (mean intensity) was positively associated with commonness (prevalence), as assumed by the core-satellite species hypothesis (hanski 1982). however, the positive correlation between prevalence and intensity was observed only when the effects of helminth body size and t ... | 1994 | 28313934 |
| oogenesis in homozygotes and heterozygotes for robertsonian chromosomal rearrangements from natural populations of the common shrew, sorex araneus. | female common shrews in their first pregnancy were collected near oxford (uk) from the hybrid zone between the oxford and hermitage races. these races differ by robertsonian chromosomal rearrangements and both robertsonian heterozygotes and homozygotes are found in the zone. the three homozygotes examined in this study had significantly more oocytes than the six heterozygotes. among the heterozygotes, the number of oocytes tended to be lower in more severely heterozygous individuals; one double ... | 1994 | 8182595 |
| the ecotoxicological significance of cadmium intake and residues in terrestrial small mammals. | little is known about the ecotoxicological hazard of cadmium to wild small mammals. this paper reviewed laboratory and field studies to determine: (i) intake and residue lowest-observable-adverse-effect-levels (loaels) for the ecologically important parameters of reproduction and development; (ii) whether these loaels are exceeded by wild small mammals on contaminated habitats and what adverse effects result; and (iii) which species may be at most risk from cadmium. the intake loael in laborator ... | 1994 | 7529157 |
| transmission of borrelia burgdorferi s.l. from mammal reservoirs to the primary vector of lyme borreliosis, ixodes ricinus (acari: ixodidae), in sweden. | factors regulating prevalence of borrelia burgdorferi s.l. johnson, schmid, hyde, steigerwalt & brenner in ixodes ricinus (l.) were examined during 1991-1992 at bogesund, near stockholm in south-central sweden. nine species of small and medium-sized mammals (sorex araneus l., s. minutus l., neomys fodiens pennant, clethrionomys glareolus [schreber], microtus agrestis [l.], apodemus sylvaticus [l.], a. flavicollis [melchior], lepus europaeus pallas, l. timidus l.) were found to infect feeding tic ... | 1994 | 7815401 |

| descriptive kinetics of the seminiferous epithelium cycle and genome size in the mole talpa occidentalis (insectivora). | the male germ cell cytodifferentiative process of the mole talpa occidentalis is described. cytochemical procedures were used 1) to follow acrosome formation and spermatid differentiation, dividing the seminiferous epithelium cycle into ten stages, each characterized by typical germ cell-to-cell associations, and recognizing 13 steps in spermatid differentiation; 2) to monitor, in situ, histones replacement by protamines at step 11 of the spermiogenic process. the seminiferous epithelium cycle o ... | 1995 | 7561724 |
| 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 |
| fiber types and myosin heavy chain composition in muscles of common shrew (sorex araneus). | red-toothed shrews of subfamily soricinae are small mammals with very high mass-specific metabolic rate. owing to their high aerobic power they are interesting objects for studies concerning the limits and constraints of skeletal muscle adaptation. in order to clarify the correlation between metabolic rate and muscle properties, we have analyzed fiber types, fiber size, and myosin heavy chain composition of the common shrew (sorex araneus) and compared them to those of rat (rattus norvegicus). t ... | 1995 | 7852946 |
| characterization of pneumocystis carinii infection in sorex araneus from southern finland. | histologic and quantitative techniques were compared in an evaluation of the intensity of pneumocystis carinii infection in common shrews (sorex araneus) at espoo, southern finland, from september 1992 to may 1993. the histological scores were comparable to the results of the cyst count technique. the number of p. carinii cysts found in common shrews was low compared to those reported by others in clinically ill laboratory rats. the inflammatory changes detected in the lung sections had no signi ... | 1995 | 8583642 |
| gene mapping in the common shrew (sorex araneus; insectivora) by shrew-rodent cell hybrids: chromosome localization of the loci for hprt, tk, ldha, mdh1, g6pd, pgd, and ada. | we selected the common shrew (sorex araneus) to generate the first insectivore gene map. shrew-chinese hamster and shrew- mouse somatic cell hybrid cells were constructed. when the 119 shrew-rodent clones were characterized, only shrew chromosomes were found to have segregated. a panel of hybrid clones was selected for gene assignment. the genes for hypoxanthine phosphoribosyl transferase (hprt), glucose-6- phosphate dehydrogenase (g6pd), and malate dehydrogenase 1 (mdh1) were assigned to shrew ... | 1995 | 8597634 |
| fatty acids in the triglycerides and phospholipids of the common shrew (sorex araneus) and the water shrew (neomys fodiens). | fatty acid composition of the liver, brown fat, thigh muscle and heart of sorex araneus and neomys fodiens was determined by glc and glc-ms. in both species of shrew the total amounts of omega 3-pufas in the phospholipids were greater than those in the triglycerides. sorex araneus, which feeds solely on a terrestrial diet, had a larger total amount of omega 6-pufas in the triglycerides of the brown fat. the phospholipids of the thigh muscle and heart of neomys fodiens, however, contained more om ... | 1995 | 7584849 |
