L. de Castro; J. A. L. Silva 2007 11 páginas Abstract A non-linear age structured model is presented for the Ibera Caiman yacaré population. We consider the placement of the nests (related to the temperature in the nest) as the determining factor for the sex of the hatchlings. The dynamical behavior and the effects of management strategies as harvest and eggs collection are studied through numerical simulation.
