Autor: Morgan J Trimble, Rudi J van Aarde

Publikováno v: PLoS ONE, Vol 6, Iss 1, p e16176 (2011)

Previous studies demonstrate that old-growth forest remnants and vegetation regenerating after anthropogenic disturbance provide habitat for birds in a human modified coastal dune forest landscape in northern KwaZulu-Natal, South Africa. However, occ
