Dr Yarnell is the Leader of the Ecology and Conservation Research Group and REF2021 Unit of Assessment Co-ordinator for C14 Geography and Environmental Studies. He also teaches undergraduate modules including Wildlife Management and the African Field Course, and Postgraduate module Protected Species Surveying. His research interests lie within the broad field of ecology and conservation.
Areas of research interest include:
- carnivore ecology and conservation
- population dynamics of small mammals
- focal species include brown hyaena (Parahyaena brunnea) and the European hedgehog (Erinaceus europaeus).
Current PhD students:
- Anthony Seveque (Started 2017) Trophic Cascades: the role of apex predators in Europe’s modern human- dominated landscapes.
- Jessica Schaus-Calderon (Started 2017) Using the Random Encounter Model (REM) to estimate rural and urban hedgehog population size.
- Katie Lee (50% Matched funding PTES/NTU)(Started 2017): Untangling the roles of prey availability, habitat quality and predation as predictors of hedgehog abundance.
- Shashank Balakrishna (Started 2018): Barn owl breeding success.
- Robert Davis (Started 2016) Leopard ecology and conservation in Malawi – In collaboration with Carnivore Research Malawi and Dr Emma Stone.
Past PhD students:
- Louisa Richmond-Coggan (Brown hyaena conservation in South Africa)
- Holly Root-Gutteridge (Bioacoustics of wolf howls)
- Louis Phipps (Conservation of Gyps vultures in Southern Africa)
- Tim Stratton (Using personality to improve species reintroduction success) Esther Kettle (A comparison of urban and rural behaviours in the peregrine falcon (Falco peregrinus))
- Oluseun Akinsorotan (Impacts of illegal human activities on mammal occupancy in Old Oyo National Park, Nigeria)
Opportunities to carry out postgraduate research towards an MPhil / PhD in the School of Animal, Rural and Environmental Science exist, and further information may be obtained from the NTU Doctoral School.
Dr Yarnell is a member of:
- IUCN hyaena specialist group
- British Ecological Society
- Mammal Society
- Subject Editor for the African Journal of Ecology
He is also a reviewer for the following Journals: PLoS ONE, Journal of Mammalogy, European Journal of Wildlife Research, Journal of Zoology, Oecologia, and Ecological Applications.
