| parasite aggregations in host populations using a reformulated negative binomial model. | the negative binomial distribution model is reformulated and used to demarcate a host population at a specific level of infection by defining an attribute spanning a range of parasite aggregations. the upper limit of the range specifies the boundary for the classification of the host population and provides a technique to determine the cumulative probability at any level of parasite infection to a high degree of accuracy. this approach also leads to the evaluation of the k parameter, i.e. an inv ... | 2004 | 14972038 |
| [puumala and dobrava viruses in the northeastern and central regions of bosnia]. | bosnia and herzegovina has been known as a highly endemic region for hantavirus infections for more than 50 years. previous studies have shown that at least two different hantaviruses, the murine dobrava (dob) and avricoline puumala (puu) viruses, each carried by a different rodent species, have been circulating in the area. however, there is little information on rodent population density fluctuations in bosnia over the past years as well as on the ratio of puumala to dobrava infection in human ... | 2003 | 15011464 |

| polychlorinated biphenyls in small mammals from contaminated landfill sites. | pcbs in small mammals living in a contaminated landfill site varied in both concentration and congener composition, reflecting both the feeding strategy of each species and the chlorination of the congeners. body concentrations of sigmapcb on a 1:1:1 arochlor (1242:1254:1260) basis gave a rank order of sorex araneus > apodemus sylvaticus > microtus agrestis. comparisons with data for other pcb-contaminated sites suggest that the sigmapcb values in s. araneus from the landfill site may be of suff ... | 1996 | 15091398 |
| predicting cadmium, lead and fluoride levels in small mammals from soil residues and by species-species extrapolation. | the effects of heavy metals on wild mammals are often assessed by analysing residues in body organs. this paper reviews published studies to determine whether cadmium (cd), lead (pb) and fluoride (f) residues in small mammals can be predicted directly from residues in soil or, when this is not possible, from residues in other species. it was found that residues in soil could be used to predict cd and pb concentrations in small mammals. there were significant (p < 0.05) relationships between cd r ... | 1995 | 15091546 |
| arsenic contamination in wood mice (apodemus sylvaticus) and bank voles (clethrionomys glareolus) on abandoned mine sites in southwest britain. | arsenic can be highly toxic to mammals but there is relatively little information on its transfer to and uptake by free-living small mammals. the aim of this study was to determine whether intake and accumulation of arsenic by wild rodents living in arsenic-contaminated habitats reflected environmental levels of contamination and varied between species, sexes and age classes. arsenic concentrations were measured in soil, litter, wood mice (apodemus sylvaticus) and bank voles (clethrionomys glare ... | 2000 | 15092868 |
| dioxin and furan residues in wood mice (apodemus sylvaticus) following a large scale polyvinyl chloride (pvc) fire. | a forest ecosystem was contaminated as a result of a fire involving 600 t of pvc. a wide range of 2,3,7,8-substituted dioxin and furan congeners were elevated (by up to 4-fold) on soil adjacent to the factory compared to a site 200 m from the factory perimeter. livers of wood mice (apodemus sylvaticus) caught on these areas were also analysed for dioxins and furans. toxic equivalents (teqs) were 9-fold higher in wood mice caught on the site 10 m from the factory perimeter compared with the site ... | 1997 | 15093358 |
| biochemical effect evaluation of perfluorooctane sulfonic acid-contaminated wood mice (apodemus sylvaticus). | wood mice (apodemus sylvaticus) were captured at blokkersdijk, a nature reserve in the immediate vicinity of a fluorochemical plant in antwerp, belgium, and at galgenweel, 3 kilometers farther away. the liver perfluorooctane sulfonic acid (pfos) concentrations in the blokkersdijk mice were extremely high (0.47-178.55 micro g/g wet weight). perfluorononanoic, perfluorodecanoic, perfluoroundecanoic, and perfluorododecanoic acids were found sporadically in the liver tissue of the blokkersdijk mice. ... | 2004 | 15121511 |
| sexual transmission of a nematode parasite of wood mice (apodemus sylvaticus)? | sexual transmission occurs commonly in microparasites such as viruses and bacteria, but this is an unusual transmission route for macroparasites. here we present evidence which suggests that a nematode parasite of wood mice (apodemus sylvaticus) may be sexually transmitted and we have classified the nematode using molecular data. wood mice were collected annually in the course of work on their reproductive physiology. larval nematodes were found in the epididymides of 19.6% of males. it seems li ... | 2004 | 15180324 |
| chromosome painting in the long-tailed field mouse provides insights into the ancestral murid karyotype. | we report on the hybridization of mouse chromosomal paints to apodemus sylvaticus, the long-tailed field mouse. the mouse paints detected 38 conserved segments in the apodemus karyotype. together with the species reported here there are now six species of rodents mapped with mus musculus painting probes. a parsimony analysis indicated that the syntenies of nine m. musculus chromosomes were most likely already formed in the muroid ancestor: 3, 4, 7, 9, 14, 18, 19, x and y. the widespread occurren ... | 2004 | 15237228 |
| so close and so different: comparative phylogeography of two small mammal species, the yellow-necked fieldmouse (apodemus flavicollis) and the woodmouse (apodemus sylvaticus) in the western palearctic region. | in europe, concordant geographical distribution among genetic lineages within different species is rare, which suggests distinct reactions to quaternary ice ages. this study aims to determine whether such a discrepancy also affects a pair of sympatric species, which are morphologically and taxonomically closely related but which have slight differences in their ecological habits. the phylogeographic structures of two european rodents, the yellow-necked fieldmouse (a. flavicollis) and the woodmou ... | 2005 | 15329664 |
| evolution of mhc-drb class ii polymorphism in the genus apodemus and a comparison of drb sequences within the family muridae (mammalia: rodentia). | allelic diversity at major histocompatibility complex (mhc) genes is thought to be maintained by balancing selection over long periods of time, even across multiple speciation events. trans-species sharing of mhc alleles among genera has been supported by many studies on mammals and fish, but in rodents, the results are ambiguous. we investigated natural levels of mhc- drb variability and evolutionary processes in the wood mouse (apodemus sylvaticus) and the yellow-necked mouse (apodemus flavico ... | 2004 | 15351919 |
| the helminth community of the wood mouse, apodemus sylvaticus, in the sierra espuna, murcia, spain. | the helminth community of the wood mouse, apodemus sylvaticus, in the sierra espuna was characterized after a complete analysis of its helminth community component and infracommunity structure relative to host age, sex and year of capture. the helminth community comprised 13 species: one trematode, four cestodes and eight nematodes. the cestode pseudocatenotaenia matovi and the nematode syphacia frederici were the most prevalent and abundant helminth species, respectively. sixty four percent of ... | 2004 | 15469624 |
| identification of bartonella species in rodents, shrews and cats in denmark: detection of two b. henselae variants, one in cats and the other in the long-tailed field mouse. | small mammals and stray cats were trapped in two areas of north zealand, denmark, and their blood cultured for hemotrophic bacteria. bacterial isolates were recovered in pure culture and subjected to 16s rdna gene sequencing. bartonella species were isolated from five mammalian species: b. grahamii from microtus agrestis (field vole) and apodemus flavicollis (yellow-necked field mouse); b. taylorii from m. agrestis, a. flavicollis and a. sylvaticus (long-tailed field mouse); b. tribocorum from a ... | 2004 | 15511270 |
| ultrastructure of the spermatozoon of the anoplocephalid cestode gallegoides arfaai (mobedi and ghadirian, 1977) tenora and mas-coma, 1978, an intestinal parasite of the wood mouse (apodemus sylvaticus linnaeus, 1758). | the present work involves an ultrastructural study of the mature spermatozoon of the anoplocephalid cestode gallegoides arfaai (mobedi and ghadirian, 1977) tenora and mas-coma, 1978, obtained from the small intestine of naturally infected wood mice, apodemus sylvaticus linnaeus, 1758 (rodentia, muridae). the mature spermatozoon of g. arfaai is a filiform cell, tapered at both ends and lacking mitochondria. it is characterized by the presence of a 1,000-nm-long apical cone and two 140-nm-thick cr ... | 2004 | 15517383 |
| cadmium and lead concentrations in gallegoides arfaai (cestoda: anoplocephalidae) and apodemus sylvaticus (rodentia: muridae) from spain. | information on parasites of vertebrates living in terrestrial ecosystems as sentinels for heavy metal environmental pollution is scarce. the aim of the present study was to assess the concentration of cadmium and lead using the model apodemus sylvaticus/gallegoides arfaai in order to test the potential suitability of g. arfaai as a sentinel organism for lead and cadmium under natural field conditions. samples of 15 a. sylvaticus as well as whole specimens of g. arfaai were analysed for both elem ... | 2004 | 15538628 |
| a parasite reveals cryptic phylogeographic history of its host. | this study compares the continental phylogeographic patterns of two wild european species linked by a host-parasite relationship: the field mouse apodemus sylvaticus and one of its specific parasites, the nematode heligmosomoides polygyrus. a total of 740 base pairs (bp) of the mitochondrial cytochrome b (cyt b) gene were sequenced in 122 specimens of h. polygyrus and compared with 94 cyt b gene sequences (974 bp) previously acquired for a. sylvaticus. the results reveal partial spatial and temp ... | 2004 | 15615681 |
| a comparison of wild-caught wood mice and bank voles in the intellicage: assessing exploration, daily activity patterns and place learning paradigms. | our previous work has revealed very high baseline neurogenesis in the dentate gyrus of wood mice as compared particularly to bank voles; a difference which may be related to learning capacity. this study explored whether the newly-developed intellicage system could be used to compare these species in simple spatial learning paradigms. the intellicage is essentially a group-housing cage that also allows continuous automatic recording of each individual's behaviour. seven wild-caught bank voles (c ... | 2005 | 15639172 |
| identification of genetic evidence for dobrava virus spillover in rodents by nested reverse transcription (rt)-pcr and taqman rt-pcr. | a survey of 158 rodents caught in the czech republic identified dobrava virus sequences closely related to that of the dobrava virus type strain in apodemus sylvaticus and mus musculus rodents. the identity of a. sylvaticus was unequivocally confirmed by random amplified polymorphic dna analysis. the data seem to indicate hantavirus spillover from apodemus flavicollis to other rodents. | 2005 | 15695684 |
| rapid g+ count and subpopulation assessment of the intestinal bacteria in apodemus sylvaticus and mus musculus by flow cytometry. | we report a novel application of calcein-acetomethyl ester in flow cytometry for rapid estimation of the number of g+-bacteria in rodent feces (apodemus sylvaticus and mus sp.f. muridae). we also use the combined application of flow cytometry and syto-13 or sypro orange staining to count rapidly the total bacterial population and to describe bacterial subpopulations in the intestine. | 2004 | 15702550 |
| phylogeography of a nematode (heligmosomoides polygyrus) in the western palearctic region: persistence of northern cryptic populations during ice ages? | this study establishes the continental phylogeographical pattern of a european nematode, heligmosomoides polygyrus (dujardin, 1845; heligmosomoidea). we sequenced 687 base pairs of the mitochondrial dna (mtdna) cyt b gene for 136 individuals collected in 22 localities. the results revealed that h. polygyrus populations are separated into five major units corresponding to the italian, northern european (denmark and ireland), iberian, western european, and balkan populations. different subclades w ... | 2005 | 15723668 |
| [evaluation of cytophysiological state of testis in forest voles living in the radioactively contaminated areas]. | we made a cytophysiological analys of testis in clethrionomus rutilus and apodemus sylvaticus inhabiting a contaminated area of the east ural radioactive trace (eurt). the study showed that in the norm these species differed in the total number of cells of spermatogenous epithelium, due to interspecific difference. in the sampling plot a concentration of 90sr in clethrionomus rutilus was 2 times higher than that in apodemus sylvaticus. maximum destructive changes in endocrine and exocrine (semin ... | 2005 | 15810529 |
| seroepidemiology of borrelia burgdorferi sensu lato and anaplasma phagocytophilum in wild mice captured in northern turkey. | an expedition across the asian part of the black sea coast and national parks of northern turkey was organized in the summer of 2001 to investigate the presence of borrelia burgdorferi sensu lato (s.l.), lyme borreliosis agent, and anaplasma phagocytophilum, human granulocytic ehrlichiosis, agent, in wild mice. a total of 65 apodemus flavicollis, apodemus sylvaticus, microtus epiroticus, crocidura suaveolens and mus macedonicus, were captured. two out of 22 apodemus sylvaticus specimens were ser ... | 2005 | 15816159 |
| the occurrence of strongylid nematodes in the epididymides of wood mice. | the recent discovery of a larval nematode in the epididymides of free-living wood mice (apodemus sylvaticus) suggests a sexual transmission of these parasites. they have been placed within the bursate nematodes (order strongylida) through 18s rdna analysis, suggesting that they are undetermined metastrongyloid nematodes. the possibility that these parasites are transmitted sexually opens an intriguing field of research because sexually transmitted metazoan parasites are known to occur mainly in ... | 2005 | 15927528 |
| disruption of a host-parasite system following the introduction of an exotic host species. | the potential of biological invasions to threaten native ecosystems is well recognized. here we describe how an introduced species impacts on native host-parasite dynamics by acting as an alternative host. by sampling sites across an invasion front in ireland, we quantified the influence of the introduced bank vole (clethrionomys glareolus) on the epidemiology of infections caused by flea-transmitted haemoparasites of the genus bartonella in native wood mice (apodemus sylvaticus). bartonella inf ... | 2005 | 15977903 |
| [changes in liver of apodemus sylvaticus mice from east-ural radioactive territories]. | male microtus arvalis mice from radionuclide polluted territories in the south urals (90sr activity of ground--0.2, 2, 500, 800 ci/km2) were used. the 90sr content in a mouse bony skeleton was determined. carbohydrate, energy and protein metabolism, lipid peroxidation processes in liver were studied. the intensification of protein and carbohydrate enzymes. on the increase of antioxidant activity we found the reduction of lipid peroxidation processes. the decrease of microsome oxidoreductases was ... | 2005 | 16080629 |
| sexual dimorphism in metapodial and phalanges length ratios in the wood mouse. | relative length of metapodials and digits is sexually dimorphic in most primates and one rodent and one bird species studied so far. recently, interest in digit ratios has increased because of their correlation with diverse physiological, psychological, and performance traits in humans. these correlations may reflect the effect of androgens during early ontogeny on digit development and their long-term organizational effects on extragenital organs. inter- and intrasexual variation in digit ratio ... | 2005 | 16110515 |
| the distribution of arsenic in the body tissues of wood mice and bank voles. | arsenic is accumulated by free-living small mammals, but there is little information on the resultant concentrations in different tissues other than liver and kidney. such information is important because the severity of toxicological effects may be related to the amount of arsenic accumulated in specific organs, and the availability of arsenic to predators is, in part, dependent on which tissues accumulate arsenic. the objective of this study was to quantify the arsenic concentrations and the p ... | 2005 | 16170450 |
| hosts and pathogen detection for immature stages of ixodes ricinus (acari: ixodidae) in north-central spain. | to determine hosts of the immature stages of a southern population of ixodes ricinus, we trapped rodents and birds in an area of north-central spain in may-june and august-september of 1998 and 1999. the most frequently trapped rodents were apodemus sylvaticus (230 specimens) and clethrionomys glareolus (99), with a larval infestation prevalence of 49% and 81%, respectively (in spring) and 21% and 41% (in summer). c. glareolus was always more heavily parasitized by larvae (mean numbers 19.8 in s ... | 2005 | 16323055 |
| cadmium and lead concentrations in skrjabinotaenia lobata (cestoda: catenotaeniidae) and in its host, apodemus sylvaticus (rodentia: muridae) in the urban dumping site of garraf (spain). | the present study evaluates the parasitological model constituted by the wood mouse (apodemus sylvaticus) and its intestinal cestode (skrjabinotaenia lobata) as a potential bioindicator of cd and pb in the urban dumping site of garraf near the city of barcelona (spain) and in begues (reference site). tissues and respective s. lobata specimens of 38 wood mice captured in garraf and begues were analyzed for cd and pb by means of icp-ms. higher cadmium levels in s. lobata were found only in respect ... | 2006 | 16376469 |
| effects of environmental pollution on microsatellite dna diversity in wood mouse (apodemus sylvaticus) populations. | ten microsatellite dna loci were surveyed to investigate the effects of heavy metal pollution on the genetic diversity and population genetic structure of seven wood mouse (apodemus sylvaticus) populations along a heavy metal pollution gradient away from a nonferrous smelter in the south of antwerp (flanders, belgium). analysis of soil heavy metal concentrations showed that soil ag, as, cd, cu, and pb decreased with increasing distance from the smelter. genetic analyses revealed high levels of g ... | 2005 | 16398127 |
| metal blood levels and hematological characteristics in wood mice (apodemus sylvaticus l.) along a metal pollution gradient. | the present study evaluated whether blood could be used as a nondestructive tool for monitoring metal exposure and related hematological effects in wood mice (apodemus sylvaticus l.) living along a metal pollution gradient. soil concentrations of arsenic, cadmium, copper, lead, silver, and zinc decreased with distance from the emission source. blood levels of cadmium and lead differed significantly among sites, whereas those of the other metals did not. blood levels of cadmium and lead correlate ... | 2006 | 16494236 |
| transfer and accumulation of metals in a soil-diet-wood mouse food chain along a metal pollution gradient. | we studied the accumulation and transfer of as, cd, cu, pb and zn in the compartments of a soil-diet-wood mouse (apodemus sylvaticus) food chain at five sites located along a metal pollution gradient. we observed a clear gradient in metal exposure at increasing distance from the smelter in all compartments of the food chain for the non-essential metals. the gradient was less clear or absent for the essential metals in acorn and mice target tissues. regression analysis showed overall strong relat ... | 2007 | 16782248 |
| considerations on the sample size of wood mice used to biomonitor metals. | the concentrations of various metals (zn, cu, mn and cr) in liver, kidneys and brain from specimens of the wood mouse apodemus sylvaticus captured from 5 sites were measured. two of the sites were in a restored mine dump, another in an area characterized by serpentized soils and the remaining two were control sites. the sample size required for statistical differentiation of the sampling sites was calculated from the mean values and the variability in bioaccumulation corresponding to each of the ... | 2006 | 16815533 |
| genotoxicity in wood mice (apodemus sylvaticus) along a pollution gradient: exposure-, age-, and gender-related effects. | we investigated the effects of environmental pollution on genetic damage in wood mice (apodemus sylvaticus) by means of the comet assay, with special attention to the role of age and gender as potential confounding variables. the present study was carried out at four sites along a pollution gradient in the vicinity of antwerp (belgium), with a nonferrous smelter as the main pollution source. we measured the concentration of heavy metals (cd, co, cr, cu, fe, mn, pb, and zn) in mouse liver and kid ... | 2006 | 16916035 |
| serological survey for viral pathogens in turkish rodents. | wild rodents (n = 330) were trapped around the villages of altindere and coşandere (maçka, trabzon province), ayder, ortan, and yolkiyi (camlihemşin, rize province), and bozdag (odemiş, izmir province) in northeastern and western turkey during april 2004. samples were tested for arenavirus, hantavirus, and cowpox virus (family poxviridae, genus orthopoxvirus, cpxv) antibodies by using immunofluorescence assays (ifas). antibodies against arenaviruses were found in eight of 330 (2.4%) rodents. are ... | 2006 | 17092901 |
| [helminth fauna of rodents (arvicolidae and muridae) from the kampinos national park]. | the aim of the study was to examine the parasite fauna of rodents living in natural environment, but in close contact with human seats (small village at the area of the natural big forest). | 2006 | 17120995 |
| pfos levels in the blood and liver of a small insectivorous songbird near a fluorochemical plant. | perfluorooctane sulfonate (pfos) is the stable end product of the degradation of various perfluorinated compounds and is the predominant compound found in the environment and biota. pfos is a widespread environmental contaminant that is found in a great diversity of wildlife species with more elevated tissue concentrations in animals from populated and industrialized areas. in this study we determined the pfos accumulation in blood and livers of a small songbird, the great tit (parus major), in ... | 2007 | 17188355 |
| by hook or by crook? morphometry, competition and cooperation in rodent sperm. | sperm design varies enormously across species and sperm competition is thought to be a major factor influencing this variation. however, the functional significance of many sperm traits is still poorly understood. the sperm of most murid rodents are characterised by an apical hook of the sperm head that varies markedly in extent across species. in the european woodmouse apodemus sylvaticus (muridae), the highly reflected apical hook of sperm is used to form sperm groups, or "trains," which exhib ... | 2007 | 17245446 |
| biomagnification of pbdes in three small terrestrial food chains. | eight polybrominated diphenyl ethers (pbde) congeners (iupac nos. 28, 47, 99, 100, 153, 154, 183, and 209) were measured in passerines (great tits--parus major), wood mice (apodemus sylvaticus), and bank voles (clethrionomys glareolus). these data were combined with previously obtained data on pbdes in common buzzards (buteo buteo), sparrowhawks (accipiter nisus), and red fox (vulpes vulpes). this enabled estimation of the biomagnification potential of pbdes in the following three terrestrial fo ... | 2007 | 17310700 |
| the dynamics of murid gammaherpesvirus 4 within wild, sympatric populations of bank voles and wood mice. | murid gammaherpesvirus 4 (muhv-4) is widely used as a small animal model for understanding gammaherpesvirus infections in man. however, there have been no epidemiological studies of the virus in wild populations of small mammals. as muhv-4 both infects cells associated with the respiratory and immune systems and attempts to evade immune control via various molecular mechanisms, infection may reduce immunocompetence with potentially serious fitness consequences for individuals. here we report a l ... | 2007 | 17347391 |
| induction and metal speciation of metallothionein in wood mice (apodemus sylvaticus) along a metal pollution gradient. | we investigated the binding of cd, cu, and zn to metallothionein (mt) and other metal-binding proteins in free-living wood mice (apodemus sylvaticus l.) captured in four areas along a metal pollution gradient. we measured total and cytosolic cd, cu, and zn concentrations in mouse liver and kidney by means of inductively coupled plasma-mass spectrometry (icp-ms). total (cu, cd, zn)-mt levels were determined in the same tissues by means of the cadmium thiomolybdate saturation assay. metal speciati ... | 2007 | 17373515 |
| molecular detection of bartonella species infecting rodents in slovenia. | rodents, collected in three zoogeographical regions across slovenia, were tested for the presence of bartonellae using direct pcr-based amplification of 16s/23s rrna gene intergenic spacer region (its) fragments from splenic dna extracts. bartonella dna was detected in four species of rodents, apodemus flavicollis, apodemus sylvaticus, apodemus agrarius and clethrionomys glareolus, in all three zoogeographic regions at an overall prevalence of 40.4%. the prevalence of infection varied significan ... | 2007 | 17374132 |
| the occurrence of the trematode plagiorchis muris in the wood mouse apodemus sylvaticus in north yorkshire, uk. | wood mice apodemus sylvaticus were trapped each september over a 13-year period, from 1993 to 2005, in a wooded area adjacent to malham tarn, yorkshire, uk. plagiorchis muris was found to be the dominant intestinal trematode and occurred in every year of sampling, with an overall prevalence of 16.9%. this appears to be the first record of p. muris in a. sylvaticus within the uk. the mean worm burden was 2.03 and the distribution of the parasite within mice was typically overdispersed. no differe ... | 2007 | 17381868 |
| detection of anaplasma phagocytophilum and ehrlichia sp. hf strains in ixodes ricinus ticks in brittany, france. | dna extracts from 156 tick pools, 18 blood specimens and 17 spleens from european woodmice (apodemus sylvaticus) collected in brittany, france were tested by pcr for the 16s rrna gene of anaplasmataceae. positive amplicons were sequenced and confirmed, either by amplification and sequencing of a second gene, or by a second pcr specific for the p44 and glta genes of anaplasma phagocytophilum and the glta gene of ehrlichia sp. hf. in addition to a. phagocytophilum, the study detected ehrlichia sp. ... | 2007 | 17391395 |
| vegetable and animal food sorts found in the gastric content of sardinian wild boar (sus scrofa meridionalis). | authors report results emerging from gastric content analysis from n. 96 wild boars hunted in sardinia isle, during the hunting tide (2001-2005), from november to january. mean ph of the gastric content was 3.77 +/- 0.69. mean total capacity (tc) of each stomach was 1702 +/- 680 g. mean stuff ratio (cw/tc) between the content weight (cw) and stomachs tc was 0.45. food categories found in animal stomachs were: 19 categories of vegetal species (allium spp., arbutus unedo, arisarum vulgare, avena f ... | 2007 | 17516948 |
| do wood mice (apodemus sylvaticus l.) use food selection as a means to reduce heavy metal intake? | food preference of wood mice from two with heavy metals polluted sites and two unpolluted sites was tested under laboratory and field conditions with two-way choice experiments. in the laboratory, wood mice preferred to eat acorns from unpolluted sites over acorns from polluted sites. previous experience with polluted food had no influence on food choice. preference was negatively related to acorn metal content. furthermore, the nutrient content of the acorn endosperm was consistently lower in p ... | 2008 | 17555856 |
| impairment of endothelium-dependent relaxation of aortas and pulmonary arteries from spontaneously hyperlipidemic mice (apodemus sylvaticus). | we evaluated the endothelial function of thoracic aortas and pulmonary arteries in a population of european wood mice (apodemus sylvaticus), which exhibit hypercholesterolemia. according to the plasma cholesterol level, mice were divided into two groups: hypercholesterolemic (ahl, total plasma cholesterol 200-300 mg/dl) and normocholesterolemic (anl, total plasma cholesterol <200 mg/dl). acetylcholine (ach) caused endothelium-dependent relaxation of precontracted aortas and pulmonary arteries. r ... | 2007 | 17616485 |
| ecological differences and coexistence in a guild of microparasites: bartonella in wild rodents. | the study of ecological differences among coexisting microparasites has been largely neglected, but it addresses important and unusual issues because there is no clear distinction in such cases between conventional (resource) and apparent competition. here patterns in the population dynamics are examined for four species of bartonella (bacterial parasites) coexisting in two wild rodent hosts, bank voles (clethrionomys glareolus) and wood mice (apodemus sylvaticus). using generalized linear model ... | 2007 | 17645030 |
