Deputy Director of Graduate Studies

Academic Activities

My research and teaching activities revolve around the conservation of threatened species, with a particular focus on population ecology and amphibians and reptiles. Current projects include: researching amphibian declines and extinctions; evaluating actions to reduce developmental impacts on great crested newts and other species; developing survey and reintroduction protocols; wildlife trade and long-term population monitoring. This work is carried out in collaboration with a wide range of partners around the world, particularly in the UK, Europe, Latin America and Madagascar. Within DICE my research group utilises a well-equipped ecology laboratory and an on-campus field-trials area. We also maintain a small collection of amphibians and reptiles that provide the ex-situ components for a number of ongoing conservation programmes. Both undergraduate and postgraduate students have the opportunity to gain hands-on experience in captive management methods, and to participate in surveys of local amphibian and reptile populations.

Research Interests

Population, community and behavioural ecology. Global amphibian declines and extinctions. Conservation of reptiles. Survey and monitoring protocols for biodiversity.

Assessment and mitigation of threats to amphibian populations

Although it is widely acknowledged that amphibians may be declining faster than other vertebrate classes, the threats that they face are diverse and complex. Understanding these threats and their impact on population dynamics is an essential first step in designing effective tools to neutralize them. In Britain, the effectiveness of current strategies to mitigate development threats to great crested newts is being investigated in combination with long-term population studies of this fully protected species. In addition, the use of amphibians as indicators of wider biodiversity is being tested. Related projects are investigating the role of captive breeding and reintroduction in species conservation planning, and analysing the impact of amphibian conservation programmes.

Species recovery programmes on islands

Some of the world's most threatened amphibian species occur on islands. In addition to their conservation importance, islands often provide natural laboratories for testing hypotheses about species declines and potential species recovery following threat mitigation. Current projects are focusing on endemic species on Indian Ocean islands (particularly Madagascar and the Seychelles), and how landscape change and habitat fragmentation are impacting on declining amphibian and reptile populations on Jersey.

Design of survey and monitoring programmes for reptiles and amphibians

Assessing the abundance and distribution of species is fundamental to conservation planning. However, simple counts of individuals or occupied sites may bear little relationship to actual population sizes or site occupancies because of variation in how easily individuals or populations are detected. Reptiles and amphibians pose particular challenges in this regard as a wide range of variables may affect how easily they are observed and detected. Current work is exploring how mark-recapture and site occupancy models can be used to account for variation in the detectability of reptiles and amphibians, and how survey and monitoring protocols can be designed to provide more informative data on population status and distribution. In addition, the responses of animals to different types of sampling devices - such as traps and cover objects - are being compared with a view to optimising sampling strategies. Work is particularly focusing on newts, slow-worms, grass snakes and adders.
