我们结合联合收割机的结果与现场数据的狼（狼），野猪（猪），野生动物水库结核病的捕食系统，研究捕食如何可能有助于疾病控制在多宿主系统。结果表明，捕食可以导致感染的流行率显着降低，而不会导致宿主种群密度的减少，因为由于捕食的死亡率可以通过减少疾病引起的死亡率来补偿。因此，一个关键的发现是，一个人口窝藏一个致命的感染，可以调节在一个类似的密度，在高流行率的疾病或捕食低流行率。因此，捕食者可能提供了一个关键的生态系统服务，应考虑到人类食肉动物的冲突和保护和重建食肉动物种群时承认。
We combine model results with field data for a system of wolves (Canis lupus) that prey on wild boar (Sus scrofa), a wildlife reservoir of tuberculosis, to examine how predation may contribute to disease control in multi-host systems. Results show that predation can lead to a marked reduction in the prevalence of infection without leading to a reduction in host population density since mortality due to predation can be compensated by a reduction in disease induced mortality. A key finding therefore is that a population that harbours a virulent infection can be regulated at a similar density by disease at high prevalence or by predation at low prevalence. Predators may therefore provide a key ecosystem service which should be recognised when considering human-carnivore conflicts and the conservation and re-establishment of carnivore populations.
