Biological Control Of Aleutian Island Arctic Fox: A Preliminary Strategy, Edward W. West, Robert L. Rudd
International Journal for the Study of Animal Problems
The intentional introduction of exotic animals can generally be expected to yield unanticipated biological consequences. Single-purpose introductions frequently result in ecological catastrophe. Islands are particularly vulnerable to such assault. Arctic foxes [Alopex lagopus), released for fur farming on the Aleutian Islands, formerly devoid of land predators, have significantly altered nesting avifaunal diversity, abundance, and productivity. A program for restoring the historical distribution and abundance of critically affected bird species is described. In a long-term study, biological control methods are proposed to test the hypothesis that introduced sterile red foxes [Vulpes fulva), apparently, a competitively superior species, will markedly …
