Ecology and conservation of the jaguar (Panthera onca) in the Cerrado grasslands of central Brazil

摘要: Owing to habitat conversion and conflict with humans, many carnivores are of conservation concern. Because their elusive nature, camera trapping is a standard tool for studying carnivores. In vertebrates, sex-specific differences in movements – therefore detection by cameras likely. We used data spatially explicit sexspecific capture-recapture models estimate jaguar density Emas National Park the central Brazilian Cerrado grassland, an ecological hotspot international importance. Our model considered trap encounter rates between genders location traps (on/off road). compared results estimates from non-spatial model. The spatial estimated 0.29 jaguars 100km showed that males moved larger distances had higher than females. Encounter off-road were one tenth those on-road traps. model, capture probability females; was here at 0.62 individuals 100km. nonspatial likely overestimated because it did not adequately account animal movements. probably underestimated assumed uniform distribution within outside reserve. Overall, preferable explicitly considers allows incorporating site-specific individual covariates. With both methods, lower reported most other study sites. For rare species such as grassland jaguars, capturerecapture present important advance informed planning.
