Ariadna Arnau successfully deployed three satellite transmitters on loggerheads at Wassaw Island, Georgia last week. Stay tuned for updates. We are particularly interested in their internesting habitat use and indicators of feeding status.

ACCSTR student Renato Saragoça Bruno found that green turtle diet in Nicaragua has not changed much since the last assessment in the 1980s. And curiously, nesting females in Tortuguero, Costa Rica consume terrestrial vegetation during the nesting season.
