Lead ammunition is still widely used in the UK, despite growing international concern about its environmental and health impacts. However, after centuries of use, things are on the cusp of change, with the ‘lead debate’ at a crossroads (Cromie et al., 2019). Recent research by this team (Newth et al., 2019) has identified diversity in the perspectives and practices of ammunition users and, at this pivotal moment, there is an urgent need to better understand how topographical, ecological and social factors interact to produce, reduce, and remediate environmental contamination.

This interdisciplinary project will investigate spatial and behavioural variation and change in the use, distribution, and impacts of both lead and non-toxic ammunition. Combining innovative approaches from geography and environmental sciences, the student will develop skills in ecotoxicology, ecosystem health assessment and contemporary social research methods, as well as experience working at the science/policy interface. The collaborative CASE partnership will involve working with specialists at the Centre for Ecology and Hydrology and the Wildfowl and Wetlands Trust and engaging constructively with ammunition users and shooting organisations in a range of contexts. It also offers opportunities to examine the impacts of both lead and non-toxic shot on different species and habitats (e.g. gamebird and wildlife exposure, wounding rates, and plastic pollution), and investigate the environmental effects and social processes of transitioning from lead to non-toxic ammunition.

Raptor introductions, reintroductions or translocations are rare, and the scientific literature associated with them is usually retrospective, considering in a historical context why they have succeeded or failed. The proposed translocation of hen harriers, Circus cyaneus, to southern England, presents an extraordinary opportunity to study a raptor translocation in its early stages and as it unfolds. The ecological drivers of translocation outcomes are manifold: including population viability; Allee effects; demographic stochasticity; environmental fluctuations; diet and other dimensions of ecological niche; prey population dynamics; breeding success; behavioural interactions; dispersal and natal philopatry. The social drivers are similarly manifold: deliberative practices, means of engagement and communications; existing disputes, wider conflicts and policy differences; complex relationships among individuals and stakeholder groups. Ecological and social processes are likely to interact, both in anticipation of and during the translocation. Incorporating social-ecological approaches will bring new insights into conservation practice in contested arenas.

This PhD will take a broad view of raptor translocations, using the case study of hen harriers in England, to deepen our understanding of the ecological and social drivers of the outcomes of these important conservation actions.

Wildcats are Britain’s only Critically Endangered mammal. Following centuries of intensive predator control, wildcats are now protected but restricted to a population of about 200 individuals living in low productivity habitat in the Scottish Highlands, where they are threatened principally by hybridization with domestic cats. This project will investigate the potential for, and challenges to, wildcat recovery and restoration outside of their current Scottish refugium, to their former range in Wales and England.

The student will undertake interdisciplinary work towards understanding the ecological and social feasibility and practicalities of wildcat restoration. They will conduct qualitative studies of the challenges of reconciling wildcat conservation with the interests of domestic cat owners, and of potential conflict with farming and shooting interests. Quantitative studies will address the suitability of source populations of wildcats (including captive-breeding), population viability, landscape suitability and means of managing hybridization. Their academic aims will include building a social-ecological network around conservation of iconic species in contested landscapes, alongside delivering applied outcomes of protocols and practices towards reintroductions.

The student will work with partners at The Vincent Wildlife Trust (www.vwt.org.uk), who have recently led the successful restoration of pine martens to Wales, and global conservation leaders, the Durrell Wildlife Conservation Trust (www.durrell.org). Project supervisors are Professor Robbie McDonald of the University of Exeter’s Environment and Sustainability Institute (http://www.exeter.ac.uk/esi/people/profile/index.php?web_id=Robbie_McDonald), Dr Steve Carter of the Vincent Wildlife Trust and Dr Rich Young of the Durrell Wildlife Conservation Trust. Renowned conservationist Professor Carl Jones will be a project advisor.

Hazel dormouse conservation is a top priority for UK woodlands (Photo by Danielle Schwarz CC BY-SA 3.0)

Despite their strict protection and major conservation efforts, populations of hazel dormice Muscardinus avellanarius in England and Wales continue to decline. Recent analyses by the University of Exeter (Goodwin et al 2017) identified a 72% decline in dormouse populations from 1993 to 2014 and suggested that the species could be categorized as Endangered in the UK. Our recent work (Goodwin et al 2018a, b) has also highlighted the importance of improving woodland management to enhance the conservation status of the species in the UK.

This collaborative CASE studentship will involve fieldwork on dormice and forestry practice. The student will work alongside key conservation organisations to build on recent work on dormouse ecology and to evaluate and improve woodland management practices in order to reverse the fortunes of this most endearing British mammal.

The overall aim of this project is to understand variation in dormouse conservation status, evaluate woodland management and provide evidence for improved practices to support dormouse recovery in the UK. This will be achieved by extensive analysis of dormouse populations and of woodland characteristics, using remotely sensed data, accompanied by intensive surveys of dormice and habitats in a sample of commercial and non-commercial, broadleaf and coniferous woodlands. The student will survey woodland managers to understand practice in relation to conservation regulation and commercial and other management objectives. The student will also have the opportunity to employ molecular genetic techniques to understand dormouse population processes and to develop population models to understand how variation in practice might affect populations in the long term. The student will work at public and private forests across England and Wales, sampling sites at which dormice are thriving and sites where they are in decline. The project will require extended periods of fieldwork away from Cornwall, and periods in the laboratory in Cardiff and at Forest Research.

Polecats (Mustela putorius) are regularly exposed to pesticides in Britain.

Rodents are a major problem on farms and present a threat to food security as well as human and animal health and welfare. Rats alone cost the UK about £200M a year by consuming and contaminating growing and stored crops. The problem is primarily managed, with varying degrees of success, by using anticoagulant rodenticides.

However, these chemicals are economically, ethically and environmentally problematic because they are markedly inhumane, resistance is a growing problem and their usage leads to widespread exposure of non-target wildlife, including threatened species of birds and mammals. In Britain, studies show that most polecats, barn owls and red kites are now exposed to rodenticides, with implications for their conservation. Guidance is available for the improved usage of rodenticides on farms, but we know relatively little about how this guidance works in practice and what improvements remain still to be made. The use of innovative and, in some cases, non-lethal Integrated Pest Management techniques, holds potential for increasing efficacy while reducing the multiple problems of established practices for rodent control, including the risks rodenticides pose to wildlife.

This CASE studentship will provide training in the science underpinning sustainable agriculture and food security by working towards more effective, economic and humane management of wildlife in the farm environment. The student will undertake evaluations of variation in rodent control practices and outcomes, conduct experiments on current and innovative approaches to rodent management and model approaches and outcomes to enhance best practice. They will adopt an interdisciplinary approach to research on wild animal populations and behaviour and on farmers and contractors and their practices and will work in the field and laboratory. The student will join a large group of interdisciplinary, applied researchers (wildlifescience.org) in Professor Robbie McDonald’s research group at the University of Exeter’s Penryn Campus and will work alongside Professor Richard Shore at the Centre for Ecology and Hydrology (ceh.ac.uk) and Alexandra Tomlinson and Ruth Layton at our CASE partners sankalpa (oursankalpa.org).

Dairy farming is a major part of the Cornish economy. Although cattle usually graze outdoors, they tend to be housed in large barns/sheds over winter. At this time their environment can be severely affected by flocks of tens of thousands of starlings that fly into the barns/sheds to take cattle feed. The starlings can severely deplete cattle feed supplies, defecate in the barn and cause a nuisance for farm workers.

We are seeking a research ecologist to lead development of innovative solutions to mitigating the impacts of starlings on the farmed environment, specifically dairy farms. The successful applicant will lead a project gauging the impact of starlings on farms, and will work with partners in the USA to evaluate sonic deterrents to reduce their impact.
