摘要

Due mainly to habitat destruction, feline species are threatened with extinction in Brazil. The future of feline research and conservation can benefit from the knowledge about these species and how they are managed in zoos. The present study analysed how the information contained in the Zoological Information Management System (ZIMS) and the scientific literature can be complementary to understanding the current scenario of studies on the species, highlighting the gaps in knowledge, and evaluating the ex-situ population dynamics. The results indicated that all threatened feline species are kept and bred in zoos. There was a population decline for Leopardus tigrinus and L. colocolo and an increase for L. wiedii and L. guttulus, while the other species showed stabilization in captive populations. Age pyramids suggest future growth for Panthera onca and L. wiedii captive populations. Species with restricted distributions, such as L. colocolo and L. tigrinus, are less frequent in zoos, reproduce less ex-situ, and the age pyramids indicate a future decline of captive populations. The most charismatic species, P. onca and Herpailurus yagouaroundi, have been the most studied. Despite the increase in studies in the 2000s, knowledge gaps remain, especially in genetic and reproductive studies. The findings of this study underscore the need for further research and the potential for zoos to play a significant role in the conservation of Brazilian wild felines, playing parts not only in the maintenance of viable ex-situ populations but also in filling knowledge gaps with individuals from their collections in scientific research.
