| corrections in the names of rodent coccidia (apicomplexa, coccidiasina). | the following new taxonomic combinations are introduced for coccidia whose names were previously given erroneously: dorisa bengalensis (bandyopadhyay & ray, 1982) n. comb. from the indian palm squirrel funambulus pennanti in india; eimeria sicistae from the intestine of the birch mouse sicista tianschanica in the ussr; e. hydrochaeri carini, 1937 emend. from the capybara hydrochaerus hydrochaerus in south america; frenkelia sp. (doby, jeannes & rault 1965) from the brain of the water vole arvico ... | 1987 | 3123645 |
| 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 |
| prisoners in their habitat? generalist dispersal by habitat specialists: a case study in southern water vole (arvicola sapidus). | habitat specialists inhabiting scarce and scattered habitat patches pose interesting questions related to dispersal such as how specialized terrestrial mammals do to colonize distant patches crossing hostile matrices. we assess dispersal patterns of the southern water vole (arvicola sapidus), a habitat specialist whose habitat patches are distributed through less than 2% of the study area (overall 600 km²) and whose populations form a dynamic metapopulational network. we predict that individuals ... | 2011 | 21931775 |
| influence of land mosaic composition and structure on patchy populations: the case of the water vole (arvicola sapidus) in mediterranean farmland. | the ability of patchy populations to persist in human-dominated landscapes is often assessed using focal patch approaches, in which the local occurrence or abundance of a species is related to the properties of individual patches and the surrounding landscape context. however, useful additional insights could probably be gained through broader, mosaic-level approaches, whereby whole land mosaics with contrasting patch-network and matrix characteristics are the units of investigation. in this stu ... | 2013 | 23875014 |
| comparative study of g- and c-banded chromosomes of five species of microtidae: a chromosomal evolution analysis. | g-banded karyotypes were compared in the following species of microtidae: microtus nivalis, m. cabrerae, m. arvalis, and arvicola sapidus. previous observations on a. sapidus and a. terrestris were also incorporated in this study. the results show that robertsonian translocations and pericentric inversions are common mechanisms involved in the karyotypic evolution of this group. interspecific differences on the g-banding patterns were also analysed, and an attempt was made to establish a presump ... | 2011 | 3061873 |
| inventory of wild rodents and lagomorphs as natural hosts of fasciola hepatica on a farm located in a humid area in loire atlantique (france). | with the objective of studying the role of wild fauna in the epidemiology of fasciolosis disease, a definitive wild-host inventory was carried out in a french farm where infected domestic hosts (cows) cohabit with wild potential ones. liver flukes, faecal eggs and antibodies were looked for in lagomorphs (oryctolagus cuniculus) and rodents (myocastor coypus, ondatra zybethicus, rattus norvegicus, arvicola sapidus and micromammal species) trapped in the study area. presence of fasciola hepatica w ... | 2000 | 10887652 |
| variable conservation of nucleolus organizer regions during karyotypic evolution in microtidae. | the location of the nucleolus organizer regions (nors) was studied in four species of microtidae (microtus nivalis, m. cabrerae, m. arvalis, and arvicola sapidus). the comparative study of these locations shows that some nors have been conserved despite the chromosome rearrangements that have occurred through karyotypic evolution, while others have been lost. in addition, there are many chromosomes in which nors seem to have appeared or been lost without apparent relation to the chromosome rearr ... | 1990 | 2185132 |
| sex chromosomes pairing in two arvicolidae species: microtus nivalis and arvicola sapidus. | arvicolid rodents present both synaptic and asynaptic sex chromosomes. we analyzed the pairing behaviour of sex chromosomes in two species belonging to this rodent group (microtus nivalis and arvicola sapidus). at pachynema, the sex chromosomes of both species paired in a small region while the rest remain unsynapsed. consequently at metaphase i, sex chromosomes present end-to-end association. thus, the pairing behaviour of sex chromosomes in these species is very similar to that previously desc ... | 2003 | 12921162 |
| heterogeneous road networks have no apparent effect on the genetic structure of small mammal populations. | roads are widely recognized to represent a barrier to individual movements and, conversely, verges can act as potential corridors for the dispersal of many small mammals. both barrier and corridor effects should generate a clear spatial pattern in genetic structure. nevertheless, the effect of roads on the genetic structure of small mammal populations still remains unclear. in this study, we examine the barrier effect that different road types (4-lane highway, 2-lane roads and single-lane unpave ... | 2016 | 27219505 |
| phylogeography of southern water vole (arvicola sapidus): evidence for refugia within the iberian glacial refugium? | the role of southern european peninsulas as glacial refugia for temperate species has been widely established, but phylogeographic patterns within refugia are being only recently addressed. here we describe the phylogeographic patterns for southern water vole (arvicola sapidus) in its whole distribution across iberia and france. control region and cytochrome b sequences were obtained for 228 samples from 130 localities across iberia and france. eighty-five haplotypes were found in total yielding ... | 2009 | 19674304 |
| structure, organization and nucleotide diversity of the mitochondrial control region and cytochrome b of southern water vole (arvicola sapidus). | the southern water vole (arvicola sapidus miller, 1908) is an endangered rodent whose conservation guidelines should preserve the current genetic variability. we analyze the structure and organization of the mitochondrial control region (cr) in a. sapidus. the cr of this species is characterized by a low guanine-cytosine content, the absence of any repetitive motif within the two hypervariable regions, and the presence of the two extended termination-associated sequences and conserved sequence b ... | 2010 | 20334495 |
