Abundƒncia relativa, padräes de atividade e uso de habitat de on‡a-pintada e on‡a-parda no norte da Amaz“nia Brasileira
2013  Full Book

The study of the abundance, activity, and habitat use of the jaguar and puma in the Amazon region has not been widespread as in other biomes due to factors such as accessibility, climate and environmental conditions, which hinders the development of research and a broader view of how human activities impact these biological aspects of these top predators. We conducted a search in the settlement Entre Rios (anthropic area) and the Biological Reserve UatumÆ (conservation unit), north of the Amazon River using camera trapping aiming to raise information on the abundance of the jaguar (_Panthera onca_) and the puma (_Puma concolor_), their activity patterns and habitat use. During 69 days in Entre Rios and 76 days in REBIO UatumÆ we reported the presence of jaguars in both areas, recording the puma only for REBIO UatumÆ. The abundance of jaguars was higher in REBIO UatumÆ than in Entre Rios. The jaguar was active during the daytime period in Entre Rios and in REBIO UatumÆ it was active in crepuscular-daytime and nighttime periods, while the puma was active along the day. The habitat use of jaguars both in Entre Rios and in REBIO UatumÆ occurred more frequently in the lowland marshland, and the habitat use of pumas in REBIO UatumÆ occurred more frequently in the plateau and slope, mountainous non-flooded areas of low elevation. The results of this study showed the abundance of jaguar and puma are of the greatest already registered for the Amazon, the activity of both jaguar and puma were temporally overlapped and there was spatial segregation as a way to avoid competition.
