“…All markers were highly polymorphic and allelic richness indicated similarly high level of genetic variation. Such maintenance of high genetic variation, despite great fluctuations in population density and thus possible threat of repetitive bottlenecks, has already been observed in yellow‐necked mouse (Gortat et al., ; Kozakiewicz et al., ; Rico et al., ) and in several vole species (e.g., Aars et al., ; Berthier et al., , ; Ehrich & Jorde, ; Ehrich et al., ; Gauffre, Estoup, Bretagnolle, & Cosson, ; Gauffre et al., ; Plante, Boag, & Bradley, ; Redeker et al., ; Rikalainen et al., ; Vuorinen & Eskelinen, ). The authors explained a minor impact of often dramatic decline in population size (up to 90% of population; Rikalainen et al., ) by constant and relatively large effective population size, intense migration negatively correlated with density, and the consequential accumulation of new alleles during the population peaks.…”

“…Genetic studies on yellow-necked mice are scarce and mostly restricted to phylogeography (Michaux, Libois, & Filippucci, 2005;Michaux, Libois, Paradis, & Filippucci, 2004). The only studies that aimed at including landscape features in explaining the genetic structure of yellow-necked mice had been focused on evaluating the direct effect of natural and anthropogenic barriers on defined a priori population and covered a small geographical scale (Gortat et al, 2010;Kozakiewicz et al, 2009;Rico, Kindlmann, & Sedláček, 2009).…”

The goal of this study, conducted in seven large woodlands and three areas with small woodlots in northeastern Poland in 2004–2008, was to infer genetic structure in yellow‐necked mouse Apodemus flavicollis population and to evaluate the roles of environmental and population ecology variables in shaping the spatial pattern of genetic variation using 768 samples genotyped at 13 microsatellite loci. Genetic variation was very high in all studied regions. The primal genetic subdivision was observed between the northern and the southern parts of the study area, which harbored two major clusters and the intermediate area of highly admixed individuals. The probability of assignment of individual mice to the northern cluster increased significantly with lower temperatures of January and July and declined in regions with higher proportion of deciduous and mixed forests. Despite the detected structure, genetic differentiation among regions was very low. Fine‐scale structure was shaped by the population density, whereas higher level structure was mainly shaped by geographic distance. Genetic similarity indices were highly influenced by mouse abundance (which positively correlated with the share of deciduous forests in the studied regions) and exhibited the greatest change between 0 and 1 km in the forests, 0 and 5 km in small woodlots. Isolation by distance pattern, calculated among regions, was highly significant but such relationship between genetic and geographic distance was much weaker, and held the linearity at very fine scale (~1.5 km), when analyses were conducted at individual level.

Conversion of formerly continuous native habitats into highly fragmented landscapes can lead to numerous negative demographic and genetic impacts on native taxa that ultimately reduce population viability. In response to concerns over biodiversity loss, numerous investigators have proposed that traits such as body size and ecological specialization influence the sensitivity of species to habitat fragmentation. In this study, we examined how differences in body size and ecological specialization of two rodents (eastern chipmunk; Tamias striatus and white‐footed mouse; Peromyscus leucopus) impact their genetic connectivity within the highly fragmented landscape of the Upper Wabash River Basin (UWB), Indiana, and evaluated whether landscape configuration and complexity influenced patterns of genetic structure similarly between these two species. The more specialized chipmunk exhibited dramatically more genetic structure across the UWB than white‐footed mice, with genetic differentiation being correlated with geographic distance, configuration of intervening habitats, and complexity of forested habitats within sampling sites. In contrast, the generalist white‐footed mouse resembled a panmictic population across the UWB, and no landscape factors were found to influence gene flow. Despite the extensive previous work in abundance and occupancy within the UWB, no landscape factor that influenced occupancy or abundance was correlated with genetic differentiation in either species. The difference in predictors of occupancy, abundance, and gene flow suggests that species‐specific responses to fragmentation are scale dependent.

“…Other studies in central Europe have reported subtle genetic structuring for rural Apodemus spp. populations (Rico et al 2009;Gortat et al 2010Gortat et al , 2012 whereas genetic drift can lead to genetic differentiation at short distances within the urban landscape (Gortat et al 2012).…”

Evaluating connectivity between Natura 2000 sites within the montado agroforestry system: a case study using landscape genetics of the wood mouse (Apodemus sylvaticus)

Context The Natura 2000 network is the centerpiece of European nature conservation policy but its effectiveness is challenged by ongoing landscape change. Objective Our objective was to assess landscape connectivity between Natura 2000 sites in the biodiversity-rich western Mediterranean region. Methods We used the wood mouse as a focal species with short-range dispersal and obtained genetic data for 393 individuals uniformly distributed between two Natura 2000 sites in SW Portugal. We created a map of connectivity between the two sites that was based on a stack of analyses including reciprocal causal modeling and least-cost path modeling coupled with resistant kernel analysis. Results Wood mice in the study area were genetically diverse and connected by gene flow over a large area. We did not find evidence of major population subdivision in the study area. Gene flow was limited by geographic distance, with significant genetic similarity between individuals within 3 km of each other. Vegetation cover and land use explained more of the variation in genetic distance than geographic distance alone. In particular, agroforestry areas and transitional woodland were associated with higher costs to movement than forest or arable land uses. This result may have been influenced by the difficulty in classifying land use in the open montado. Conclusions The Natura 2000 sites we studied are well connected by multiple corridors for dispersal. Our analysis also highlighted the importance of the Serra de Grândola, part of the European Long Term Ecological Research Network but not yet included in Natura 2000.
