Silva 1c2007  a11 páginas  aAbstract  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. 4aIbera922437 4aYacare9124820 4aCaiman99403 4aEdad919167 4aModelos99559 4aDeterminación de la Edad9120774 4aDeterminación del Sexo9122962 4aCosecha98585 4aHuevos964620 4aComportamiento987220 tEcological Modellinggv. 186 (2005)w234631  cART  a(INICN)37539234742  c234742d234742  aAR-ReUNNbspacAR-ReUNNeaacr2
