Habitat loss and fragmentation are primarily responsible for the reduction of populations of carnivores mammals. The scenario is even more critical in regions where agricultural expansion is intense and as a consequence species losses may be higher in biomes considered hotspots. Impacts on carnivores populations may be potentiated as a result of an increasing and significant threat, the introduction of exotic species such as free ranging dogs and cats. Larger species are expected to be the most affected by anthropic impacts and their absence leads to increased entry of dogs and cats into protected areas. Thus, the entry of exotic species can make this scenario even more complex, leading to changes throughout the mammal community. The main objective of the project will be to evaluate the main factors that favor the entry of exotic species such as dogs and cats in protected areas, as well as to understand the spatial and temporal co-occurrence among these species. Data from North American and Brazilian protected areas will be analyzed and the uniqueness of the relationships between exotic and wild carnivores will be analyzed in different contexts. The results will guide management and conservation measures both for the evaluated areas, many of them protected areas still without management plan, as well as for the species of carnivores, among them many endangered species.
