In search of the ideal underpass for wild animals
In search of the ideal underpass for wild animals

Designing crossing structures for wildlife underneath roads is a challenge because species may respond differently to factors such as nearby habitat or crossing-structure dimensions. Here we show that large, open crossing structures along natural travel corridors accommodate the highest diversity of large and medium-sized mammals.

Priority regions and species to study and protect from road impacts in Latin America
Priority regions and species to study and protect from road impacts in Latin America

We identified key areas and species that should be prioritized for conservation and research related to road impacts. In Latin America, vultures, armadillos, cuckoos and shrew opossums need protection, and Central America and northern South America are the regions with the greatest need for research.

More than 10,000 tons of wild mammals are killed on Brazilian roads yearly: Assessing the impacts and conservation implications of wildlife-vehicle collisions

Nearly 9 million medium- and large-sized mammals (>1kg) could be killed on Brazilian roads each year, representing an estimated wildlife biomass of over 10,000 tons. Mortality from roads is a major threat to wildlife conservation in Brazil, and further research and mitigation is urgently needed to avoid species extinction.
