Through advanced isotopic analyses, Rodnyel Arosemena seeks to understand how fish in the Caribbean and the Pacific that had a common ancestor take advantage of the resources of their different environments today.
A groundbreaking study of 7000-year-old exposed coral reef fossils reveals how human fishing has transformed Caribbean reef food webs: as sharks declined by 75% and fish preferred by humans became smaller, prey fish species flourished —doubling in numbers and growing larger. This unprecedented look into prehistoric reef communities shows how the loss of top predators cascaded through the entire food web, shifting the balance amongst coral reefs.
I’ve gotten used to performing long-term studies, and shorter-term field experiments, but most of all try to mix and match what is both interesting and useful. Many studies have come to fruition, and those I continue to expand consider 1) ecology and taxonomy of stingless bees and orchid bees, 2...
