Using faecal glucocorticoid metabolite analyses to elucidate stressors of African wild dogs Lycaon pictus from South Africa
There are few stressful factors which have been investigated to affect adrenocortical function in the African wild dog (AWD) Lycaon pictus. Understanding what animals perceive as stressors is important for not only the implementation of management practices promoting general animal welfare in captivity, but also because a prolonged stress perception is known to disrupt reproduction, […]
Compassionate versus consequentialist conservation
Ethical treatment of wildlife and consideration of animal welfare have become important themes in conservation, but ethical perspectives on how best to protect wild animals and promote their welfare are diverse. There are advantages to the consequentialist harms ethical framework applied in managing wild herbivores for conservation purposes. To minimize harms while achieving conservation goals, […]
Strategic animal welfare issues: ethical and animal welfare issues arising from the killing of wildlife for disease control and environmental reasons
Ethical and animal welfare concerns about the destruction of free-living wildlife for disease control and environmental reasons have historically received little attention from animal welfare scientists, legislators or the public. Nevertheless, all vertebrates can experience pain and distress, regardless of whether they are unwanted pests or not. A wide range of methods is used to […]

A Non-Invasive System for Remotely Monitoring Heart Rate in Free-Ranging Ungulates
A new, external non-invasive telemetric heart rate (HR) monitoring system was evaluated on eight wapiti, Cervus elaphus canadensis, yearlings in July and August 1996. The assembly consisted of a leather girth strap, onto which a HR transmitter and a customized carriage bolt electrode system were fixed. To prevent the girth strap from rotating on the […]
Animal welfare and pest control: meeting both conservation and animal welfare goals
Vertebrate pest control is an area where conservation and animal welfare goals can be in direct conflict. Is it possible to meet goals in both areas in one pest control operation? Vertebrate pests, including unwanted or overabundant wildlife, are controlled for many reasons related to protecting the health, safety and comfort of humans, animals and […]
Trade-offs between welfare, conservation, utility and economics in wildlife management — a review of conflicts, compromises and regulation
In choosing among alternative wildlife management techniques, trade-offs between animal welfare and conservation, utility or economics are often apparent. This paper reviews the roles of science, scientists, regulators and educators in attempts to overcome this inter-dependence and to make simultaneous progress on all fronts. Illustrations are drawn in particular from trapping and pest population control. […]
Fertility Control: An Option for Non-Lethal Control of Wild Carnivores?
Three types of fertility control, surgical sterilization, hormonal chemosterilization, and immunosterilization, are reviewed with regard to their potential for controlling problematic populations of carnivores. The fertility control agent and delivery protocol of choice may vary considerably according to: (i) the reason for control; (ii) the degree, urgency and duration of population reduction required; (iii) concerns […]
Potential welfare impacts of kill-trapping European moles (Talpa europaea) using scissor traps and Duffus traps: a post mortem examination study
Moles are widely trapped as pests on farms and amenity land in Britain. Spring traps for killing mammals generally require welfare approval in the UK, but mole traps are exempt. Previous research demonstrated wide variation in the mechanical performance of mole traps. In this context, we aimed to produce new data on the welfare impact […]
