Ontogenetic Changes in Feeding Behaviors in Tufted Capuchins. [PDF]
ABSTRACT Objectives Wild juvenile capuchins exhibit lower feeding success than adults, particularly for mechanically challenging foods, but ontogenetic changes in oral food processing behaviors related to this reduced success are unknown. We test how oral food processing efficiency varies across development in an experimental setting in tufted ...

Growth-defense trade-offs promote habitat isolation between recently-diverged species. [PDF]
Growth–defense trade‐offs have long been implicated in tropical plant diversity, but how do these tradeoffs contribute to reproductive isolation? This study characterizes growth–defense trade‐offs between two recently diverged tropical plants and explore their role in maintaining strong habitat isolation.
