them to exploit large areas. Thus, the ecosystem functions in which they are involved and the services they provide probably develop at spatial scales of unknown range6,24,25. In fact, it has been postulated that the most specialist group of species (Gypsspp.) evolved in a context of resou...
It was concluded that most concentrations compared well with those reported for other avian species, but concentrations of Cr, Ni and Pb in the dead vultures were generally above values characteristic of heavy metal poisoning. The values reported for each of two wild populations of P. africanus ...
Special attention should be put on the carrion removal service since previous studies have shown that the absence of carrion consumers such as vultures can have great impact on human health and significantly increase mortality due to the proliferation of carrion-associated bacteria and other diseases ...
We measured FID in eight species of waterbirds in two coastal lagoon environments with different protection regimes, taking into account age classes and whether individuals were grouped or alone. Species markedly differed in FID: average distance ranged between 50 (little egret, Egretta garzetta, ...
