Our research focus
The Environmental Biology group has an international reputation for its studies on the effects of natural and anthropogenic environmental change on animals, their populations and ecosystems. Our research spans studies on fundamental biological process to the development and application of solutions for the protection of animal health and ecosystems. Aquatic biology is a major focus (freshwater and marine - fish, invertebrates, reptiles and mammals) but terrestrial insects, birds and humans are also important species studied.
Ecotoxicology is a key research area, having a globally important impact on our appreciation of how endocrine disruptors, nanoparticles, pharmaceuticals, agrochemicals, plastics, climate change and noise affects ecosystem health.
Understanding mechanisms of action and physiological/behavioural adaptations to environmental stressors is vital to predicting impacts on populations and improving the sustainability of aquatic and terrestrial food production. Approaches used include field tracking studies, in vivo experimentation, in vitro techniques, novel transgenic fish models, population genetics, genome-wide sequencing, and ecological modelling. We have a £12M state-of-the-art facility (Aquatic Resources Centre) for supporting our laboratory-based freshwater and marine research.
Recent research highlights
Investigating initiatives to tackle deforestation
Across Southeast Asia, conversion of forests to rubber plantations is a major cause of deforestation. Dan Bebber and a team of national and international collaborators calculated the minimum price for forest carbon required to break even against potential earnings from rubber plantations. Unfortunately, the study concluded that rubber is so valuable that the minimum required carbon price far exceeds that paid on carbon markets.
New method for population genetics
An international partnership between the University of Exeter (Jamie Stevens) and University of Illinois has recently developed the first method of its kind for standardising the analysis of Restriction site-Associated DNA sequencing (RAD-seq) data, a technique of increasing importance within the field of population genetics.
Satellite tracking provides unique insight into basking shark migration
Research led by Matt Witt has applied satellite tracking to monitor the seasonal migration of basking sharks, the world’s second largest fish species. Deploying 70 satellite tags over four years, the research team observed migrations that spanned nine geo-political zones and the High Seas, demonstrating the need for multi-national cooperation in the management and conservation of this species.
Mitigating the effects of carbon dioxide on aquaculture
Sustainable aquaculture is critical for global food security. In their recent publication in Global Change Biology, Rod Wilson and colleagues bring together the fields of climate change and aquaculture science to highlight the need for cross-disciplinary research aimed at mitigating the negative impacts of elevated CO2 on future aquatic ecosystems and the sustainability of fish and shellfish aquaculture.
