Considering Extinction of Dependent Species during Translocation, Ex Situ Conservation, and Assisted Migration of Threatened Hosts

摘要: Translocation, introduction, reintroduction, and assisted migrations are species conservation strategies that attracting increasing attention, especially in the face of climate change. However, preventing extinction suite dependent whose host threatened is seldom considered, effects on moving hosts unclear. There no published guidance how to decide whether move species, given this uncertainty. We examined dependent-host system 4 disparate taxonomic groups: insects feather-leaf banksia (Banksia brownii), montane (B. montana), Stirling Range beard heath (Leucopogon gnaphalioides); parasites wild cats; mites ticks Duvaucel's gecko (Hoplodactylus duvaucelii) tuatara (Sphenodon punctatus); internal coccidian Cirl Bunting (Emberiza cirlus) Hihi (Notiomystis cincta). used these case studies demonstrate a simple process for use species- community-level assessments efforts conserve dependents with their hosts. The tigers (Panthera tigris) appeared represent assemblages would not be conserved by ex situ conservation. In contrast, cases we involving single (internal birds mite Geckobia naultina gecko), also species. may insufficient maintain viable populations additional such as supplementing needed.
