We studied the effects of landscape structure, habitat loss and fragmentation on genetic differentiation of Moor frog populations in two landscapes in The Netherlands (Drenthe and Noord-Brabant). Microsatellite data of eight loci showed small to moderate genetic differentiation among populations in both landscapes (FST values 0.022 and 0.060, respectively). Both heterozygosity and population differentiation indicate a lower level of gene flow among populations in Noord-Brabant, where populations were further apart and have experienced a higher degree of fragmentation for a longer period of time as compared to populations in Drenthe. A significant isolation-by-distance pattern was found in Drenthe, indicating a limitation in dispersal among populations due to geographic distance. In Noord-Brabant a similar positive correlation was obtained only after the exclusion of a single long-time isolated population. After randomised exclusion of populations a significant additional negative effect of roads was found but not of other landscape elements. These results are discussed in view of improving methodology of assessing the effects of landscape elements on connectivity.

Quantifying and disentangling dispersal in metacommunities: how close have we come? How far is there to go? (2010, background): “…such differentiation relative to the landscape (Walker et al. 2007), smaller values from pair-wise population comparisons indicating less differentiation and thereby higher rates of gene flow/dispersal (Arens et al. 2007; see Balkenhol et al. 2009 for future directions for landscape genetics).”
The pond network: can structural connectivity reflect on (amphibian) biodiversity patterns? (2011, background): “Since it addressed to the level of organisms, conservation biology should be mainly interested in functional connectivity (Lindborg and Eriksson 2004; Broquet et al. 2006; Arens et al. 2007; Jordán et al. 2007).”
Graph models of habitat mosaics. (2009, background): “…2007) or field experiments that allow animals to choose among cover types and so quantify resistances (Ovaskainen 2004; Belisle 2005), and genetic data (Cushman et al. 2006; Arens et al. 2007; McRae & Beier 2007) or isotopic analysis (Cook et al. 2007), which can verify inferences about movement.”
Landscape genetics of the Alpine newt (Mesotriton alpestris) inferred from a strip-based approach (2011, methodology): “we developed a straightforward and flexible procedure based on strips between populations (Vos et al. 2001; Arens et al. 2007).”
Habitat fragmentation reduces genetic diversity and connectivity among toad populations in the Brazilian Atlantic Coastal Forest (2009, background): “A number of studies have reported changes in genetic diversity associated with habitat fragmentation in reptiles and amphibians (Hitchings and Beebee, 1997, 1998; Andersen et al., 2004; Wahbe et al., 2005; Arens et al., 2007; Noël et al., 2007; Telles et al., 2007).”
