“…Prey selection. -Data on mammals, reptiles, and birds recorded at more than ve of our monitoring stations and previously described or recorded as jaguar prey (see González and Miller 2002;Duarte et al 2022) were considered as possible drivers of jaguar occupancy patterns. Among all the mammals detected, we considered only four mammals as potential jaguar prey, i.e., agouti (Dasyprocta leporina), black-eared opossum (Didelphis marsupialis), giant anteater (Myrmecophaga tridactyla), and white-tailed deer (Odocoileus virginianus) (Table 1).…”

Patterns of detectability and occupation of the jaguar (Panthera onca) vary throughout its distribution, being determined primarily by vegetation cover, prey availability, and anthropogenic factors. However, there is still a large knowledge gap regarding what determines jaguar occupancy, especially in the Amazon. This knowledge gap is even more pronounced for oceanic islands, which represent unique and very sensitive ecosystems, such as the Maracá-Jipioca Islands of the Northeastern Brazilian Amazon. Our study aimed to establish the spatial ecology of jaguars in this insular ecosystem and to provide information to facilitate sustainable management of the population there. We assessed how different factors (vegetation type and prey availability) potentially influence detectability and occupancy patterns of the jaguars of the Maracá-Jipioca Islands. We found that greater wetland (beach-sea and lagoon-channel) cover was the main driver of jaguar detectability and occupancy. We reveal factors driving the population and spatial ecology of jaguars in an insular system. Despite imminent threats to the region, the knowledge we present can inform the sustainable management of jaguars to ensure that the fundamental and unique ecosystem services provided by this top predator are maintained.
