Over the past 100 years roads have become a dominant landscape feature and this infrastructure continues to expand. Recently, concerns about the potential effects of roads and traffic on wildlife have been increasing. For example, roads and road kill are considered significant threats in the listing of several threatened species in Canada, and road mortality is the largest single component of mortality for some wildlife populations. However, to date there are almost no studies evaluating the relationship between road density and wildlife population sizes. My first objective is to determine the size of the impact of roads and traffic on wildlife populations, independent of and in comparison to other landscape changes such as habitat loss.

在过去的100年里，道路已经成为一个主要的景观特征，而且这种基础设施还在不断扩大。最近，人们越来越关注道路和交通对野生动物的潜在影响。例如，在加拿大几种受威胁物种的名单中，道路和道路死亡被认为是重大威胁，道路死亡率是一些野生动物种群死亡率的最大单一组成部分。然而，到目前为止，几乎没有研究评估道路密度和野生动物种群规模之间的关系。我的第一个目标是确定道路和交通对野生动物种群的影响大小，独立于其他景观变化（如栖息地丧失），并与之进行比较。
