Improvement of vegetation structure enhances bird functional traits and habitat resilience in an area of ongoing restoration in the Atlantic Forest.

摘要: Ecological restoration is a traditional option for recovering biodiversity and ecosystem functions. Birds perform pollination, seed dispersal, pest-control services, which catalyze increases in habitat structure. Habitat complexity changes bird composition, but there little evidence of its effects on functional diversity Neotropical restorations. We tested whether composition respond to increased complexity. Point-counts were performed (January-December 2015) an area undergoing (536 ha) the Atlantic Forest southeastern Brazil, restorations with less more structured vegetation pastures forest-fragments. The traits considered diet, habitat, biomass, environmental sensitivity, foraging strata. Increased was evaluated using plant characteristics (exotic grass, canopy, herbaceous cover, diameter at breast height). A total 172 species (5% endemic; 12% migratory) recorded. structure both restored sites forest-fragments drove reorganization addition traits, positively influenced richness, dispersion, evenness. Shifts plant-characteristics rearranged (diet-forest-dependence diet-strata-foraging). rapid development key factor because it provides additional semi-dependent forest birds enhances resilience sustainability new man-made forests.
