Researchers count manatees using their chatter to recognize individuals
September 05, 2024
An improved method of identifying manatees by their vocalizations makes it easier to tell them apart, to better estimate their populations and help efforts for their conservation.

Rediscovering the Undiscovered: Revitalizing the Cerro Juan Diaz Archaeological Ceramic Collection (Presentation in Spanish)
September 30, 2024
This research expands knowledge about the archaeological ceramics of the Gran Cocle culture at the Cerro Juan Diaz Archaeological Site, which spans a period of occupation from 200 BC to 1550 AD and is one of the largest pre-Hispanic communities in central Panama.

Hopeful News for Caribbean Reefs? Low Oxygen May Be More Deadly for Staghorn Corals than High Temperatures
October 25, 2024
First experimental comparison of the effects of temperature and oxygen deprivation on three key Caribbean coral species shows that nightly low oxygen tips the balance of species survival away from tall, elegant, reef-building corals, towards lower, weedy corals, simplifying coral communities.

Leatherback sea turtle behavior: stay near home or set off across the ocean?
October 30, 2024
A new study finds that leatherback sea turtles tend to migrate rather than forage when chlorophyll, primary productivity, and sea surface temperature levels are lower.

Drawing out the secrets of coral reef resilience to high ocean temperatures
June 05, 2025
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.

Human fishing reshaped Caribbean reef food webs, 7000-year old exposed fossilized reefs reveal
June 30, 2025
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.
