What to do when stopping over: behavioral decisions of a migrating songbird during stopover are dictated by initial change in their body condition and mediated by key environmental conditions

The behavioral decisions of migratory songbirds during migration stopovers can markedly influence the pace, efficiency, and success of …

Fruit removal rate depends on neighborhood fruit density, frugivore abundance, and spatial context

Fleshy-fruited plants depend fundamentally on interactions with frugivores for effective seed dispersal. Recent models of frugivory …
