Habitat quality is more important than matrix quality for bird communities in protected areas
Protected areas are meant to preserve native local communities within their boundaries, but they are not independent from their surroundings. Impoverished habitat quality in the matrix might influence the species composition within the protected areas through biotic homogenization. The aim of this s...

Protected areas are meant to preserve native local communities within their boundaries, but they are not independent from their surroundings.
