When going through stressful situations, some people lose their appetite. Similarly, animals that are scared for their lives tend to eat less. In nature, this behavioral change could have downstream effects. Dumas Galvez, a postdoctoral fellow at the Smithsonian Tropical Research Institute (STRI) wondered how fear of predation could influence the consumption patterns of important seed dispersers such as the Central American agouti, a rodent that loves munching on the seeds of Attalea butyracea, a tropical palm tree also known as corozo, palma real o palma de vino.

Imagine trying to understand how climate change affects vast tropical forests by determining how many trees die each year. Clouds get in the way of satellite views and on-the-ground estimates are expensive and impractical in remote areas. But researchers at the Smithsonian Tropical Research Institute (STRI) are excited by a new analysis that explains variation in tree mortality based on drone images of 1500 hectares of the most-studied tropical forest, Barro Colorado Island, in Panama.

Between 2010 and 2011, two research expeditions sponsored by the Spanish government exploring the biodiversity of benthic organisms —those living on the ocean floor— on Central America’s Pacific and Caribbean coasts, came across a new shark species. The Squatina mapama n. sp., collected off the Caribbean coast of Panama became the first record of an angel shark from the Central American Caribbean. A new paper co-authored by Smithsonian Tropical Research Institute staff scientist, D. Ross Robertson, described and named it.
