Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide
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 am broadly interested in the genetics of adaptation and speciation. How do new species form? How does adaptive variation arise and spread? How is morphological variation created through development and modified by natural selection? Is evolution predictable?
The focus of my lab’s...
Smithsonian marine biologist Ross Robertson suspects that the regal demoiselle hitched a ride to the Gulf of Mexico on an oil rig. Its outstanding success in its new habitat raises questions about its impact in the Gulf.
As researchers ask which disease-carrying mosquito species will rule Panama’s Azuero Penninsula (and perhaps the world), they discover culinary delights along the way.
