BackgroundCurrent strategies to control rodent pests have substantial environmental impact, relying on baits that are highly toxic to vertebrates and attract non-target species such as wood mice, bank voles and field voles. High persistence of these toxins and bioaccumulation then leads to widespread secondary poisoning of avian and mammalian predators and scavengers1. For example, anticoagulant rodenticide residues have been reported in 95% of barn owls2, 70% of red kites, 67% of hedgehogs3 and 79% of polecats4 in the UK.ObjectivesThis project will focus on ways to reduce the exposure of non-target species to harmful control measures aimed at rodent pests. Key objectives will be to- Improve understanding of the interactions between non-target species and invasive rodent control strategies, and the impacts on non-target species.- Develop new approaches to mitigate the impact of rodent control on non-target animals.- Demonstrate the effectiveness of new approaches in real world situations through field testing and monitoring.The student will have opportunities to carry out behavioural investigations to understand non-target exposure and establish potential avenues for mitigation; to develop and test promising approaches to reduce exposure under natural and semi-natural conditions; and to monitor and/or model effectiveness in natural populations.Novelty & TimelinessThe project addresses an urgent need to reduce the costs of rodent control for wildlife in the face of increasing problems due to anthropogenic change. Reliance on highly toxic anticoagulant rodenticides persists, despite widespread contamination of the natural environment, because of the need for effective control of highly invasive rodents. The project will build on some promising research in the host laboratory that could help reduce the harmful costs to wildlife.1 Elliott JE et al.

背景目前控制啮齿动物害虫的策略对环境产生了巨大的影响，这些策略依赖于对脊椎动物具有剧毒并吸引非目标物种（例如木鼠、银行田鼠和田鼠）的诱饵。这些毒素的高持久性和生物累积性会导致鸟类和哺乳动物捕食者和食腐动物广泛的二次中毒1。例如，据报道，英国 95% 的仓鸮 2、70% 的红鸢、67% 的刺猬 3 和 79% 的鸡貂 4 中都残留有抗凝血灭鼠剂。 目标 该项目将重点研究如何减少非目标物种接触针对啮齿动物害虫的有害控制措施。主要目标是 - 提高对非目标物种和入侵性啮齿动物控制策略之间的相互作用以及对非目标物种的影响的理解。 - 开发新方法来减轻啮齿动物控制对非目标动物的影响。 - 通过现场测试和监测，展示新方法在现实世界中的有效性。学生将有机会进行行为调查，以了解非目标暴露并建立潜在的缓解途径；开发和测试有希望的方法来减少自然和半自然条件下的暴露；新颖性和及时性该项目解决了在人为变化导致的问题日益增加的情况下降低野生动物啮齿动物控制成本的迫切需要。尽管自然环境受到广泛污染，但由于需要有效控制高度侵入性啮齿动物，人们仍然依赖剧毒抗凝血灭鼠剂。该项目将以主办实验室的一些有前途的研究为基础，这些研究有助于减少对野生动物造成的有害成本。1 Elliott JE 等人。 (2016) 生物科学 66:401-72 https://pbms.ceh.ac.uk3 Dowdling 等人 (2010) 环境污染 158:161-64 Sainsbury 等人 (2018) 环境污染 I236:689-98
