Researchers compared DNA from corals and their symbiotic organisms from two sites along the Pacific coast of Panama to better understand how the different members of the coral holobiont influence their ability to tolerate temperature extremes.
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.
Estimating shark populations on degraded Caribbean reefs is complicated, especially when there few around. A pioneering member of the O’Dea lab has developed a technique to estimate shark populations — both past and present — using their microscopic skin scales

In the Collin Lab we work to understand how environmental conditions, their natural variation and environmental change from the climate emergency shape marine ecosystems and biodiversity. Our current work focuses on three areas (1) Documenting the biodiversity of tropical marine invertebrates, (...

I am interested in the evolution and the ecology of marine organisms, particularly sea urchins, but also fishes, crustaceans, and corals. I focus on the processes that give rise to new species, and I use molecular tools to reconstruct the history of populations and of genes. Typically, this...
