Relationships between body mass and percentage of threatened species harvested (black histogram) and between mass and likelihood of being harvested for threatened vertebrates (purple line). Species whole (n) corresponds to variety of threatened species only.

Maintaining biodiversity is crucial to ecosystems and human societies, yet species’ populations and geographic ranges are collapsing all over the world .
