Habitat use under latent predation risk: A case study with wintering forest birds
Article Abstract:
Predation risk is a strong selective pressure influencing many aspects of life history of animals with important implications in the evolution of several morphological and behavioral adaptations, such as the differential use of the habitat. Selection of feeding locations within habitat follows a pattern minimizing predation risk and interspecific dominance hierarchies lead to the exploitation of unfavorable risky patches by subordinate species.

Tradeoffs between food abundance and predation danger in spatial usage of a stopover site by western sandpipers, Calidris mauri
Article Abstract:
The process of the distribution of food abundance and predation danger interaction is tested to explain spatial usage by migratory western sandpipers, Calidris mauri. The results suggest that the spatial usage by western sandpipers balances the tradeoff between the opposing spatial gradients in food and safety.
