Abstract

Summary Wild carnivores are threatened by human activities, particularly by lethal responses to livestock predation. As natural prey populations decline, predation of livestock and consumption of discarded livestock ‘waste’ (carcasses and body parts) should increase. We investigated whether parameters linked to the production of livestock waste affected the likelihood of livestock predation. We interviewed 160 households near Ruaha National Park in Tanzania to obtain information on households, livestock ownership, predation and parameters linked to livestock waste production. Our analysis identified parameters that affected the likelihood of predation on cattle, sheep and goats. When these parameters were controlled for, we found an increased likelihood of cattle predation as waste from diseased and slaughtered cattle increased. Sheep predation was more likely and cattle predation was less likely as sheep deaths from starvation increased. Goat predation was more likely in medium-sized than smaller or larger villages, suggesting a trade-off to predators between the increasing benefit of more livestock waste and the costs of higher human disturbance and diminishing natural prey abundance as village size category increased. Our findings suggest that improved disposal of livestock waste from slaughtered cattle and measures to decrease cattle deaths from disease should reduce predation of highly prized cattle.

人为食物来源是否增加了鲁阿哈国家公园周边地区的牲畜捕食?
野生食肉动物受到人类活动的威胁,特别是对牲畜捕食的致命反应。随着自然猎物数量的减少,牲畜的捕食和丢弃的牲畜“废物”(尸体和身体部位)的消费应该增加。我们调查了与牲畜废物产生有关的参数是否会影响牲畜捕食的可能性。我们采访了坦桑尼亚鲁阿哈国家公园附近的160户家庭,以获取有关家庭、牲畜所有权、捕食和与牲畜废物生产有关的参数的信息。我们的分析确定了影响牛、绵羊和山羊被捕食可能性的参数。当控制了这些参数后,我们发现由于病牛和屠宰牛的粪便增加,牛被捕食的可能性增加。绵羊被捕食的可能性更大,而牛被捕食的可能性更小,因为绵羊死于饥饿的人数增加了。相对于较小或较大的村庄,山羊更有可能在中型村庄中捕食,这表明随着村庄规模的增加,捕食者在更多牲畜粪便带来的收益增加与更高的人类干扰成本之间进行了权衡,并减少了自然猎物丰度。我们的研究结果表明,改善屠宰牛的牲畜粪便处理和减少牛死于疾病的措施应该减少对高价值牛的捕食。

期刊介绍: Environmental Conservation is one of the longest-standing, most highly-cited of the interdisciplinary environmental science journals. It includes research papers, reports, comments, subject reviews, and book reviews addressing environmental policy, practice, and natural and social science of environmental concern at the global level, informed by rigorous local level case studies. The journal"s scope is very broad, including issues in human institutions, ecosystem change, resource utilisation, terrestrial biomes, aquatic systems, and coastal and land use management. Environmental Conservation is essential reading for all environmentalists, managers, consultants, agency workers and scientists wishing to keep abreast of current developments in environmental science.
