Global Decline in the Size of Sea Turtles
Changes in mean adult body size may be a universal response to global warming and sometimes lead to conservation concerns. Using a 30-year data set for green turtles from Malaysia, we show a decrease...

Low growth rates at high population densities in sea turtles - Marine Biology
Over 29 years (1996–2024) in a lagoon environment in the Chagos Archipelago (Indian Ocean) we conducted a mark-recapture growth rate study during which 135 juvenile hawksbill turtles (Eretmochelys imb...
