The ecology of a cryptic predator, Paleosuchus trigonatus, in a tropical rainforest
The ecology of the crocodilian Paleosuchus trigonatus was studied for 8 yr near Manaus, Brazil. The population dynamics of the species is mainly influenced by the high survival rates of adults. Estimated minimum ages at reproduction are 11 yr for females and 20 yr for males. Juveniles have high rate...
