Wildlife Biology, Volume 2025, Issue 4, July 2025.Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes are more likely to become extinct. The prevention of extinctions is an urgent matter and knowledge on the ecology and distribution of threatened species is required to outline conservation strategies.

Highway Noise Worsens the Edge Effect on Bird Richness in Tropical Forests
Austral Ecology, Volume 50, Issue 5, May 2025.Highway noise worsens the edge effect. ABSTRACT Anthropogenic noise represents a major threat to various taxonomic groups of fauna, especially birds, as they primarily use sound communication. Associated with the edge effect caused by highways, noise has a negative impact on birds.
