considering extinction of dependent species during translocation, ex situ conservation, and assisted migration of threatened hosts.translocation, introduction, reintroduction, and assisted migrations are species conservation strategies that are attracting increasing attention, especially in the face of climate change. however, preventing the extinction of the suite of dependent species whose host species are threatened is seldom considered, and the effects on dependent species of moving threatened hosts are unclear. there is no published guidance on how to decide whether to move species, given this uncertainty. we examined ...201222443127
isosporoid coccidiosis in translocated cirl buntings (emberiza cirlus).four of 17 cirl buntings (emberiza cirlus) involved in a trial translocation in 2004 for conservation purposes died and were examined postmortem. two of the cirl buntings showed intestinal and hepatic lesions, including necrotising enteritis, consistent with isosporoid coccidiosis, and a third had an intestinal infestation of isosporoid coccidia. sporulated oocysts from faecal samples from the birds were identified as isospora normanlevinei, a parasite previously detected in cirl bunting populat ...201021257466
song syllable variation tolerance and motor theory of song perception: the territorial reaction of cirl bunting emberiza cirlus to homologue syllables.the extent of syllable variation tolerance was tested using synthetic homologue syllables. a synthetic copy of a common syllable type of cirl bunting emberiza cirlus song was used as control. homologue syllables, in the same frequency range but shorter or longer, were created by multiplying (2/3, 5/3, 7/3) the time scale of the control syllable. by this way the specificity of homologue syllables inside (2/3) and outside (5/3 and 7/3) the syllable duration range (mean ± 2 sd) of the species were ...199124923700
biosecurity for translocations: cirl bunting (emberiza cirlus), fisher's estuarine moth (gortyna borelii lunata), short-haired bumblebee (bombus subterraneus) and pool frog (pelophylax lessonae) translocations as case studies.exposure to parasites in conservation translocations increases the risks to recipient and translocated populations from disease, and therefore there has been interest in implementing biosecurity methods. using four case examples we described how biosecurity was applied in practical translocation scenarios prior to and during a translocation and also post-release. we implemented biosecurity, including quarantine barriers, at specific points in the translocation pathway where hazards, identified b ...201727491684
