Roads
Global assessment of Mammals threatened by roadkill
Number of mammal species for which roadkill affecting <20% of their population can increase extinction risk by 10%.

Predicted total number of birds to be roadkilled each year in Latin America and the Caribbean
Total numbers were calculated by multiplying roadkill rates [individuals (ind) per kilometre per year] predicted for each species and grid cell using random regression models and species traits and location data by the total length of existing main roads (in kilometres) in each grid cell.
