Magioli, M.
Trophic, functional and isotopic ecology of terrestrial mammals of the Atlantic Forest
2018 Full Book
The knowledge about species ecology in ever changing ecosystems is necessary to understand how they persist, how they used the new habitats molded by human activities, and if they are still performing ecological functions; this kind of information is essential to subsidize the conservation of ecosystem. The objectives of this thesis are: 1) to determine if the puma (_Puma concolor_) can occupy the niche of the jaguar (_Panthera onca_) where it is functionally absent, by assessing the puma' feeding habits and comparing it to the jaguar; 2) analyze changes in resource and habitat use, and trophic structure of mammal assemblages in preserved and modified landscapes of the Atlantic Forest, Brazil, by using the analysis of carbon and nitrogen stable isotopes; 3) identify changes in the functional effectiveness of mammal assemblages in response to changes in landscape structure within the Atlantic Forest. To determine the diet of the puma, we collected fecal samples in two areas of the largest Atlantic Forest continuum and identified 15 prey taxa.
