Saving Endangered Species by Translocation: Are We Tinkering with Evolution?

摘要: species itself. Recent studies conducted in Hawaii of the Laysan finch (Telespyza cantans; Figure 1), endemic to Island, and a rock wallaby (Petrogale sp.; 2) on island Oahu suggest that translocated populations may diverge very rapidly from parent populations. If this differentiation is genetically based, such translocations represent human intervention evolutionary process, wildlife managers need consider possibility when deciding whether try translocation save threatened species. Recently Scott Carpenter (1987) called attention fact past attempts at reintroduction or have been poorly documented, leaving disadvantage planning new programs. Translocations can
