Is Wildlife Fertility Control Always Humane

摘要: Investigation of fertility control techniques to reduce reproductive rates in wildlife populations has been the source much research. Techniques targeting have diverse. Most research into methods focused upon efficacy, with few studies rigorously assessing animal welfare beyond opportunistic anecdote. However, represent several very different mechanisms action (modalities), each their own risks. We provide a review for methods, and consider role manipulation hormones (“endocrine suppression”) long-term ability animals behave normally. potential costs that are required administer treatments, including capture, restraint, surgery drug delivery, requirement repeated administration within lifetime an animal. challenge assumption modalities generate similar desirable outcomes, we argue knowledge physiology behaviour should be more adeptly applied wild management decisions. encourage managers carefully assess behavioural risks, associated handling techniques, importance positive states when selecting as means population control.
