Conservation-induced extinction

Efforts to save endangered species may, paradoxically, lead to conservation-induced extinction of other species – a phenomenon summarized by a recent study. It mostly threatens the parasite and pathogen species that are highly host-specific to critically endangered hosts. When the last individuals of a host species are captured for the purpose of captive breeding and reintroduction programs, they typically undergo anti-parasitic treatments to increase survival and reproductive success. This practice may unintentionally result in the extinction of the species antagonistic to the target species, such as certain parasites. It has been proposed that the parasites should be reintroduced to the endangered population. A few cases of conservation-induced extinction are known to have occurred in parasitic lice.
