Research interests

My research interests focus around understanding the impacts of environmental change on wildlife populations and identifying management approaches to mitigate negative effects for species of conservation concern. My previous research has looked at the influence of artificial street lighting on small mammals, farmland management on harvest mouse nesting and anthropogenic and ecological drivers of disease in common frogs.

My current research

Alien species and disease are listed as the highest-ranking causes of extinction for amphibians worldwide (Bellard et al. 2016). Climate change is an additional and growing threat that is likely to act in synergy with these pressures (Blaustein et al. 2010). Most introduced species do not become invasive; an understanding of the impacts of those that become established is important for categorising invasiveness and for informing conservation decision making. My research will utilise a field system in Wales, UK, in which both native, declining populations of amphibians can be found alongside newly discovered smooth Lissotriton vulgaris and alpine newts Ichthyosaura alpestris, both of which are non-native to the area.

Smooth and alpine newts are native to central mainland Europe, whereas smooth newts can also be found naturally across parts of the UK. The Non-Native Species Secretariat of Great Britain lists I. alpestris as a high risk species as they are known carriers of the fungal pathogen Batrachochytrium dendrobatidis (Bd) and the species is also considered an emerging threat in New Zealand where removal programmes are underway. Anecdotal reports suggest potential impacts on native amphibians in the UK, but empirical evidence for this is lacking. By combining field and modelling approaches, this project aims to elucidate the impacts of non-native newts on native amphibian populations, understand how patterns of invasion may be influenced by climate change and ultimately help inform conservation plans for native amphibians facing these potential threats.
