As such, a more refined understanding of avian seed dispersal dynamics in the Neotropics is a subject of intense interest for ecologists, evolutionary biologists, and conservation biologists. We provide an overview of emerging research themes and approaches in the field of seed dispersal by beotropical birds, followed by five detailed case studies of current work.

Adjusting effort levels in response to this information confers a selective advantage over a strategy that never updates its belief about the world ( ). This evolutionary explanation complements an earlier suggestion that, in an uncertain environment, individuals should invest more in exploring alternative options when the current food source unexpectedly deteriorates, as compared to individuals used to experiencing poor foraging returns (10). Both of these explanations highlight the significance of uncertainty for successive contrast effects.
