Understanding and reversing the widespread population declines of birds require estimating
the magnitude of all mortality sources. Numerous anthropogenic mortality sources directly …

The development and presence of roads can reduce landscape permeability, lead to habitat
loss, and increase habitat fragmentation. It is these fundamental changes in landscape …

Aim The road network is increasing globally but the consequences of roadkill on the viability
of wildlife populations are largely unknown. We provide a framework that allows us to …

Roads represent a threat to biodiversity, primarily through increased mortality from collisions
with vehicles. Although estimating roadkill rates is an important first step, how roads affect …

Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–
vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly …

Road mortality is a widely recognized but rarely quantified threat to the viability of amphibian
populations. The global extent of the problem is substantial and factors affecting the number …

The study of road mortality rates is important to identify species in need of detailed
population evaluation, to determine the effectiveness of mitigation measures or to identify …

Road-kill is the most recognized impact of traffic and an important threat for biodiversity.
Nevertheless, most research on this topic deals with particular species or with road features …

Roads have numerous direct and indirect ecological impacts on wildlife. Vehicle collisions
are a top impact of roads on birds, with tens of millions of birds thought to be killed each year …

Roads can have negative impacts on wildlife through indirect effects such as fragmentation
of habitat, or through direct effects such as fatal collisions with vehicles. Wildlife deaths on …
