Adaptation and latitudinal gradients in species interactions: nest predation in birds

Ben Freeman, Micah Scholer, Mannfred Boehm, Julian Heavyside & Dolph Schluter
Are rates of biotic interactions are stronger in the tropics? Here we investigate nest predation rates in birds, a canonical example of a strong tropical biotic interaction. Counter to expectations, daily rates of nest predation vary minimally with latitude. However, life history traits that influence nest predation have diverged between latitudes. For example, tropical species have evolved a longer average nesting period, which is associated with reduced rates of nest attendance by parents. Daily nest...
