Resumo

The spatial distribution of species is intricately linked to population dynamics, which influence species site use patterns over time. Environmental factors contribute to these dynamics, which can also be significantly affected by human impacts. Understanding the effects of environmental and human-impact variables on site use dynamics can inform effective conservation strategies. Here, we aimed to assess the relative importance of human-impacts variables (land use types, roads, human settlements) compared to environmental variables (elevation, native forest succession type, distance to water bodies) and their impact on site use dynamics of 15 medium and large-sized terrestrial mammals and four medium and large-sized terrestrial birds in total. We collected data over two years using camera-traps in two state parks of the Atlantic Forest, Brazil, under different degrees of human pressure. We modeled species detection and non-detection data using multi-season occupancy modelling and estimated site use dynamics. Human-impact variables played a greater role in extirpation than environmental variables. Moreover, in the park experiencing a higher degree of human pressures, human-impact variables exerted a greater influence on initial site use and colonization compared to environmental variables. Pastures decreased site use and colonization and increased extirpation, while primary and secondary forests increased site use and colonization of large frugivores. High traffic paved roads decreased site use and colonization and increased extirpation. Human impacts affect dynamics of site use even within restricted protected areas. Therefore, strategies that consider the surrounding landscape and involve collaboration with neighboring communities may improve conservation effectiveness. (AU)
