| multiple parasites mediate balancing selection at two mhc class ii genes in the fossorial water vole: insights from multivariate analyses and population genetics. | we investigated the factors mediating selection acting on two mhc class ii genes (dqa and drb) in water vole (arvicola scherman) natural populations in the french jura mountains. population genetics showed significant homogeneity in allelic frequencies at the dqa1 locus as opposed to neutral markers (nine microsatellites), indicating balancing selection acting on this gene. moreover, almost exhaustive screening for parasites, including gastrointestinal helminths, brain coccidia and antibodies ag ... | 2008 | 18624885 |
| serological evidence of viruses naturally associated with the montane water vole (arvicola scherman) in eastern france. | we surveyed 12 populations of the montane water vole (arvicola scherman), previously known as the fossorial form of the water vole a. terrestris, in eastern france for antibodies (immunoglobulin g) to puumala virus (puuv), lymphocytic choriomeningitis virus (lcmv), and cowpox virus (cpxv). antibodies to puuv were found in 9 (5.5%) of 164 voles from 7 populations, antibodies to lcmv were found in 13 (26.0%) of 50 voles from 2 populations, and antibodies to cpxv were found in 66 (41.8%) of 158 vol ... | 2008 | 18752422 |
| negative relationships between cellular immune response, mhc class ii heterozygosity and secondary sexual trait in the montane water vole. | heterogeneities in immune responsiveness may affect key epidemiological parameters and the dynamics of pathogens. the roles of immunogenetics in these variations remain poorly explored. we analysed the influence of major histocompatibility complex (mhc) genes and epigamic traits on the response to phytohaemagglutinin in males from cyclic populations of the montane water vole (arvicola scherman). besides, we tested the relevance of lateral scent glands as honest signals of male quality. our resul ... | 2010 | 25567924 |
| stress and demographic decline: a potential effect mediated by impairment of reproduction and immune function in cyclic vole populations. | the stress response is initially adaptive, operating to maintain homeostasis. however, chronic long-term exposure to stressors may have detrimental effects. we proposed that chronic stress may be a major factor in demographic vole cycles, inducing decline in high-density populations. we monitored four populations of the fossorial water vole arvicola scherman, which undergo pluriannual demographic cycles in the jura mountains (france). sampling was conducted during the high densities and the decl ... | 2013 | 18040973 |

| cis-bromadiolone diastereoisomer is not involved in bromadiolone red kite (milvus milvus) poisoning. | anticoagulant rodenticides (ars) are widely used pesticides to control rodent populations. bromadiolone, a second generation anticoagulant rodenticide (sgars), is authorized in france to control the population of water voles (arvicola scherman). the persistence of sgars in rodents is responsible for secondary exposure or poisoning of predators and scavengers, and is of ecological concern for the conservation of endangered species. commercial formulations are a mixture of two diastereoisomers of ... | 2017 | 28605859 |
| microtus arvalis and arvicola scherman: key players in the echinococcus multilocularis life cycle. | a broad range of rodent species are described as potential intermediate hosts for echinococcus multilocularis, a wide-spread zoonotic cestode causing alveolar echinococcosis. however, little is known about the relative contribution of these species for parasite reproduction and the maintenance of its life cycle. in a comparative study in a high endemic region in zurich, switzerland, we investigated prevalence rates and fertility of e. multilocularis in the most abundant vole species as well as t ... | 2017 | 29326950 |
| three-dimensional geometric morphometric analysis of the humerus: comparative postweaning ontogeny between fossorial and semiaquatic water voles (arvicola). | different types of locomotion in phylogenetically close rodent species can lead to significantly different growth patterns of certain skeletal structures. in the present study, we compared the allometric and phenotypic trajectories of the humerus in semiaquatic (arvicola sapidus) and fossorial (arvicola scherman) water vole taxa, using three-dimensional geometric morphometrics, to investigate the relationships between functional and ontogenetic differences. results revealed shared humerus traits ... | 2020 | 33037838 |
| do bromadiolone treatments to control grassland water voles (arvicola scherman) affect small mustelid abundance? | the use of pesticides can affect non-target species by causing population declines through indirect intoxication. small mustelids (sms; weasels, mustela nivalis l.; stoats, mustela erminea l.) consume water voles (wvs, arvicola scherman s.) and can be exposed to bromadiolone, an anticoagulant rodenticide used in some countries to reduce wv damage to grasslands. here, we investigated whether bromadiolone affected sm abundance. | 2019 | 30175431 |
