Spatial ecology of jaguars, pumas, and ocelots: a review of the state of knowledge

Abstract

Knowledge of the spatial ecology of mammalian carnivores is critical for understanding species’ biology and designing effective conservation and management interventions. We reviewed the available information about the spatial ecology of jaguars Panthera onca, pumas Puma concolor, and ocelots Leopardus pardalis, and we examined how sex and extrinsic variables affect their spatial behaviour.

Sixty‐one articles addressing home range, home range overlap, daily net displacement (straight‐line distance between two locations on consecutive days), and/or distance of dispersal of the three species were included. Meta‐analysis, ANOVA, ANCOVA, and beta regression tests were run to analyse differences among species and sexes and to elucidate the influence of other variables, such as latitude and ecoregion, on spatial behaviour.

Pumas had on average larger home ranges (mean ± SE: 281.87 ± 35.76 km2) than jaguars (128.61 ± 49.5 km2) and ocelots (12.46 ± 3.39 km2). Intersexual range overlap was higher than intrasexual range overlap in jaguars and pumas. Sex affected the home range size of all three species, but only influenced daily net displacement in ocelots. Ecoregion affected the home range size of all three species but did not significantly affect either the daily net displacement or the dispersal distance of pumas. Latitude affected the home range size of jaguars and pumas. It did not affect daily net displacement or dispersal distance in jaguars a...
