Temporal and spatial segregation of top predators (Felidae) in a Mexican tropical Biosphere Reserve

Jaguars, Panthera onca (Linnaeus, 1758), and pumas, Puma concolor 1771) are the largest felids in neotropics. Both can overlap niche axes (time, space prey), therefore potentially competing species. Segregation mechanisms presented by a low one of these facilitate coexistence. Our aim was to analyze jaguar puma temporal spatial for understanding their segregation mechanisms. Between 2015 2017, twenty-six camera trap stations were located five habitat types El Cielo Biosphere Reserve (ECBR) northeastern Mexico. Temporal activity analyzed using circular statistics time analysis. Spatial calculated with Pianka index selectivity results showed that jaguars pumas nocturnal high (? 4 = 0.77). We found an intermediate (Pianka 0.61). Jaguars more selective preferred deciduous forest. In comparison, oak-pine forest, but also used oak indicate best explains coexistence our study area, probably due both diversity reserve generalist habits puma.
