AbstractThe juvenile phase is critically important for the future of animal populations. However this phase of the life cycle is still poorly understood in ecology. In long-lived species, the juvenile phase is long and first reproduction is late; it is during the juvenile phase that mortality rate is the highest. Three hypotheses have been formulated to point out the selective pressures driving the early life patterns of juvenile‘s long-lived organisms. First, according to the ―dispersion‖ hypothesis, juveniles are forced to leave their natal area and use less profitable habitats compared to those used by adults. Second, the ―constraint‖ hypothesis predicts that juveniles have lower foraging capacities than adults. Third, the ―selection‖ hy...
