Understanding how a species moves between habitats available in its home range is key for interpreting spatial-temporal habitat selection patterns, foraging behavior, and predator-prey interactions. The use of habitat by the jaguar(Panthera onca) generally reflects the density and movement of its prey and not the availability of habitats. However, there is no information about how the species uses the habitats available in the Amazonian várzea. The objective of this study was to test if the jaguar uses the habitats available in the surroundings of várzea lakes, in proportion to their availability or if it shows preference for a specific habitat type. To achieve this objective we surveyed, on foot, the surroundings of 36 várzea lakes in the Mamirauá Sustainable Development Reserve, recording jaguar presence through observation of signs and identifying and quantifying the available habitats. Although we found signs of jaguar presence in all habitat types surveyed, the number of signs found in habitat type chavascal was greater than expected by its availability…
