Cover : Tropical biodiversity faces an array of threats, including habitat destruction, climate change, and overhunting. In this issue, a special section provides new insights into the tropical biodiversity crisis. Fundamental drivers of deforestation are changing, which has important implications for conservation strategies. Emerging threats, such as climate change, overhunting, wildfires, and exotic pathogens, could increasingly operate in synergism with habitat loss and degradation.
