Prisoners in Their Habitat? Generalist Dispersal by Habitat Specialists: A Case Study in Southern Water Vole (Arvicola sapidus)

Abstract: 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 will require a… Show more

“…The characteristics of the matrix had relatively little influence on water voles, which is in line with previous studies of the species [35]. The only consistent effect was the positive relationship between patch occupancy rate and irrigated agriculture, which was stronger during the dry season.…”

“…100% cover) wet herbaceous vegetation dominated by grasses, sedges, rushes, and reeds, which often occupy gently sloping and soft bank-margins of ponds, small streams and irrigation ditches [27], [29]. Although throughout most of its range the water vole occurs close to permanent and stable water bodies (e.g., [30]–[32]), in dry Mediterranean landscapes such as our study area, individuals often persist in seasonally flooded habitats that may become dry during the hottest months [27], [29], [33][35]. Within habitat patches, water voles form discrete and easily recognized breeding colonies [27], [33], with individuals typically showing strong site fidelity to their home ranges (mean size of about 900 m 2 , [27]) and usually moving less then about 30 m between successive days [34].…”

“…; unpublished data), even if very little bibliographical material is available (Rigaux & Charruau, 2007;Noblet, 2008;Barré, 2009;Legrand, 2009 ;Rigaux & Charruau, 2009;Hervieu, 2011;Pellegry, 2011;Sorrel, 2011;Rigaux, 2013b). Numerous studies on the water vole, carried out with more effective means (genetic) in the Iberian Peninsula also confirm this (Fedriani et al, 2002;Centeno-Cuadros et al, 2011…). Above all, there is a strong similarity on what is known about the water vole (Arvicola terrestris) in England (Stratchan & Moorhouse, 2006…).…”

“…For many small mammals in particular, the distance between natal and breeding areas can be measured as the distance between the population where the individual was born and the population where the individual reproduces (e.g., Centeno-Cuadros et al. 2011; Dey et al. 2013).…”
