Wildlife-vehicle collision mitigation: Is partial fencing the answer? An agent-based model approach

摘要: Evaluating management options for mitigating the impacts of wildlife–vehicle collisions (WVC) is a major goal road ecology. Fencing along roads in conjunction with construction wildlife passages has been widely accepted as most effective way to minimize WVC. However, limited resources often require managers focus on single method mitigation, yet relative effectiveness fences and reducing mortality restoring population connectivity unclear. Using stone marten (Martes foina, Erxleben, 1777) model species, we developed an individual-based, spatially explicit simulation develop predictions concerning performance fencing passage under different rates mortality. For five levels each, varied probability mortality, extent, number full factorial design, total 125 scenarios. We then compared impact these two mitigation approaches abundance (N) genetic differentiation (Fst) using linear regression. Our results predict that are much more than at effects abundance. Moreover, show circumstances, also differentiation. This likely driven by ability eliminate which turn increases diversity, thereby slowing across road. partial can reduce nearly well fencing. allows adequate roads. Thus, argue alone may be best cost-effective option mitigation.
