We investigated whether the probability of survival and emigration/immigration was affected by short-term drawdown (for a few months over winter) or long-term habitat drainage (a full year of drying out) in this long-lived species of low dispersal ability.

Scientists have for the first time determined the ratio of males to females in a wild foraging group of green turtles in the Eastern Pacific, which suggests that sea turtles may be vulnerable to feminization from the temperature rises expected with climate change. Leer más.
