Loss in functional diversity across 73 mammal assemblages of the Caatinga semi-arid region of South America.

Loss in functional diversity across 73 mammal assemblages of the Caatinga semi-arid region of South America.

<p>A) Relationship between functional diversity loss and defaunation rate according to the model generated. B) Relationship between functional diversity loss and the footprint of human disturbance. Both predictors are significant (p < 0.05) according to each model.</p>
