Abstract

Invasion of alien species is a concern to human well-being and a threat to biodiversity. Many thriving biological invasions causes economic damages and drives disruptions of ecosystem functioning. Along with that, defaunation process also endanger entire communities, disrupting species interactions, particularly on plant-animal interactions. In neotropical forests, tapir and peccaries play important role, regulating ecosystem functions such as herbivory, trampling of seedlings and saplings, predation and dispersal of seeds. However, they are threatened or locally extinct, jeopardizing the structure and the regeneration of plant communities. On the other hand, an alien species, the feral pig Sus scrofa is quickly occupying these defaunated landscapes. Nevertheless, the consequences of feral pigs to seed dispersal, seed predation, herbivory and trampling in the Atlantic Forest ecosystems are unknown. The aim of this Ph.D. proposal is to examine how feral pigs affect such ecological functions and process, as well estimate the differences between foraging ecology of tapir (Tapirus terrestris), peccaries (Tayassu pecari and Pecari tajacu) and the invasive, to provide tangible estimation of its impacts and of its role on ecosystems.
