1. Introduction
Traffic infrastructure and urban sprawl are major factors of habitat fragmentation in densely populated areas, contributing to impermeable landscapes for wildlife movement (Frantz et al. 2012). Impermeable landscapes may lead to a loss of functional connectivity, i.e., an increase in genetic differentiation among populations (Epps et al. 2005), reduced genetic diversity (Kuehn et al. 2007; Holderegger&Di Giulio 2010), and foster inbreeding as a consequence of reduced mate availability in small populations (Corlatti, Hacklander, & Frey-Roos 2009). Forsome wildlife (e.g., ungulates), it has been shown that traffic infrastructure such as fenced motorways are virtually impossible to pass (Hepenstrick, Thiel, Holderegger, & Gugerli 2012) whereas for other groups such as carnivores, permeability may only become reduced (BUWAL, SGW, & Vogelwarte 2001). Wildlife corridors are paths of animal movement which are restricted by natural and anthropogenic structures orintensely used areas(BUWAL et al. 2001).Increasing traffic infrastructure and the spread of settlements has impaired or blocked 72% of the regionally important corridors in Switzerland since the 1950s(BUWAL et al. 2001), especially on the Swiss Plateau, where high road densities of six to seven km road per km2 land are common (Klaus 2012). The Federal Office forEnvironment(BAFU,formerly namedBUWAL) commissioned a report with regionally and internationally important wildlife corridors. This represents the unified knowledge of hunting administration, game keepers and wildlife experts on connectivity of terrestrial wildlife and their corridors in Switzerland (BUWAL et al. 2001). The report categorized wildlife corridors into intact (i.e., fully permeable), impaired (i.e., partly permeable) and interrupted (i.e., fully impermeable). In total, only about a third (85 out of 303) were considered intact (BUWAL et al. 2001). To date, only a few, spatially restricted studies about the effects of traffic infrastructure on the genetic structure of wild ungulates are available (Coulon et al. 2004, 2006; Epps et al. 2005; Kuehn et al. 2007; Hepenstrick et al. 2012). Also, the spatial genetic structure and the effect of multiple wildlife corridors have not yet been investigated in a landscape context. We considered roe deer (Capreolus capreolus), a common and widespread species of relatively large body size, as a suitable model species for studying population genetic structure at the landscape scale. A previous study of Hepenstrick et al. (2012) showed that linear landscape elements, in particular fenced roads, induced genetic differentiation of roe deer in a nationally important wildlife corridor. The present study identified the genetic structure of roe deerin fourregions of Switzerland (300–2600 km2). The goal was to assess the permeability of the landscape by evaluating whether the genetic structure found in roe deer reflected the expert-assessed categorization of wildlife corridors into intact, impaired and interrupted. Overall, we expected to find low levels of genetic differentiation of roe deer across the landscape, since roe deer was eradicated from Switzerland or survived as relicts only in the second half of the 19th century. Around 1900, the Swiss Plateau was re-colonized in a broad front from Germany and France, and the species’ range has rapidly expanded since then. In turn, we hypothesized that roe deer on either side of interrupted wildlife corridors were genetically differentiated, reflecting barrier effects induced by landscape elements hampering gene flow. Our landscape-scale assessment relating the genetic structure to expert-assessed functionality of wildlife corridors will allow recommendations to prioritize the construction or restoration of wildlife corridors and may serve as a basis for later evaluation of the efficiency of connectivity measures promoting gene flow in roe deer.
