“…In tune with the previous work, Yang et al (2011) found that roads contributed to the genetic isolation of Chinese populations of Przewalski's gazelles (Procapra przewalskii), but railways had no influence on genetic differentiation, probably because of their low traffic flow and the presence of wildlife passes. A similar result was found for roe deer (Capreolus capreolus) in Switzerland, although in this case, the authors suggested that the differences could be due to highways being fenced and railways not, as traffic flow was similar (Hepenstrick et al 2012). In Canada, Tremblay and St. Clair (2009) showed that railways were more permeable to forest song bird movements than were roads, likely due to their narrower width and lower traffic.…”

Railways play a major role in the global transportation system. Furthermore, railways are presently being promoted by several governments thanks to their economic and environmental advantages relative to other means of transportation. Although railways have clear advantages, they are not free of environmental problems. The objective of this book is to review, assess, and provide solutions to the impacts of railways on wildlife. We have divided the impacts of railways on biodiversity into four main topics: mortality, barrier effects, species invasions, and environmental disturbances, with the latter ranging from noise to chemical pollution. Railways share several characteristics with roads and with power lines when the trains are electric. Therefore, much can be learned from studies on the impacts of roads and power lines, taking into account, however, that in railways, the two are often combined. Besides the similarities with roads and power lines, railways have specific characteristics. For instance, railways have lower traffic intensity but trains usually have much higher speeds than road vehicles, and the electric structures in railways are typically lower than in most power lines. Thus, railways pose specific challenges and require specific mitigation measures, justifying calling the study of its impacts on biodiversity "railway ecology."

“…In addition, rapid genetic subdivision due to human-made barriers, in particular, fenced highways (e.g. desert bighorn sheep, Ovis canadensis nelsoni, Epps et al 2005 and roe deer, Capreolus capreolus, Wang and Schreiber 2001; Kuehn et al 2007;Hepenstrick et al 2012), has been observed in other ungulate species (but see Finnegan et al 2012), supporting the hypothesis that road effects can be observed within a small time frame even in species with long generation times.…”

“…In addition, barriers can reduce functional connectivity among habitat patches, subdivide populations and lead to negative genetic effects (e.g. loss of genetic diversity; Hepenstrick et al 2012). Roads and other human developments are already known to restrict gene flow for smallbodied species such as amphibians (Reh and Seitz 1990;Noel et al 2007) and insects (Keller and Largiader 2003); however, it is becoming more evident that human activity can also influence species with greater dispersal capabilities (Noss et al 1996;Leveau 2013;Unfried et al 2013).…”

“…Landscape features such as mountains, rivers, and roads have been shown to influence dispersal as well as seasonal or daily movement patterns within established home ranges (Riley et al 2006;Millions and Swanson 2007;Long et al 2010). The strength and arrangement of potential barriers to movement determines the degree of connectivity among habitat patches and can ultimately influence population densities and other demographic processes (Delany et al 2010;Long et al 2010;Hepenstrick et al 2012). Spatial distribution of genetic variation relative to landscape features can provide valuable insight into the effects of potential barriers to effective dispersal (i.e.…”

Based on studies of other ungulates (Wang and Schreiber 2001;Epps et al 2005;Kuehn et al 2007;Hepenstrick et al 2012), we hypothesized that moose in and near Anchorage would show spatial genetic substructure associated with human barriers, specifically the Glenn Highway. Understanding how the distribution of genetic diversity may be related to habitat fragmentation in urban environments can inform mitigation strategies to reduce potential impacts of dispersal barriers.…”

A genetic discontinuity in moose (Alces alces) in Alaska corresponds with fenced transportation infrastructure

The strength and arrangement of movement barriers can impact the connectivity among habitat patches. Anthropogenic barriers (e.g. roads) are a source of habitat fragmentation that can disrupt these resource networks and can have an influence on the spatial genetic structure of populations. Using microsatellite data, we evaluated whether observed genetic structure of moose (Alces alces) populations were associated with human activities (e.g. roads) in the urban habitat of Anchorage and rural habitat on the Kenai Peninsula, Alaska. We found evidence of a recent genetic subdivision among moose in Anchorage that corresponds to a major highway and associated infrastructure. This subdivision is most likely due to restrictions in gene flow due to alterations to the highway (e.g. mooseresistant fencing with one-way gates) and a significant increase in traffic volume over the past 30 years; genetic subdivision was not detected on the Kenai Peninsula in an area not bisected by a major highway. This study illustrates that anthropogenic barriers can substructure wildlife populations within a few generations and highlights the value of genetic assessments to determine the effects on connectivity among habitat patches in conjunction with behavioral and ecological data.

In the early 1800s, the European roe deer (Capreolus capreolus) was probably extirpated from Switzerland, due to overhunting and deforestation. After a federal law was enacted in 1875 to protect lactating females and young, and limiting the hunting season, the roe deer successfully recovered and recolonized Switzerland. In this study, we use mitochondrial DNA and nuclear DNA markers to investigate the recolonization and assess contemporary genetic structure in relation to broad topographic features, in order to understand underlying ecological processes, inform future roe deer management strategies, and explore the opportunity for development of forensic traceability tools. The results concerning the recolonization origin support natural, multidirectional immigration from neighboring countries. We further demonstrate that there is evidence of weak genetic differentiation within Switzerland among topographic regions. Finally, we conclude that the genetic data support the recognition of a single roe deer management unit within Switzerland, within which there is a potential for broad‐scale geographic origin assignment using nuclear markers to support law enforcement.
