Biological Sciences (Evolution, Ecology and Behaviour)

We study patterns in the natural environment, from the behaviour of individual organisms to dynamics of populations and the diversity of communities. Our aim is to go beyond description of these patterns - we wish to understand the ecological and evolutionary factors that drive them. Research in theInstitute of Infection, Veterinary and Ecological Sciencesspans the range of biosciences. From the fine-scale resolution of biomolecular structure, through the genome-wide analysis of cells and organisms, to the evolution and ecology of organisms in their natural environment. Underpinning this diversity, we offer world-class facilities and infrastructure for research, and superb links to internationally excellent partners in both the academic and industrial sectors. Within this Institute, theDepartment of Evolution, Ecology and Behaviourworks with viruses, bacteria, fungi, animals, insects, plants and humans, using state-of-the-art technologies and mathematical models to understand the principles that underlie biological diversity. The research seeks to answer fundamental questions and address key issues of contemporary concern. We seek to understand the ecological and evolutionary dynamics of disease in wildlife populations. Our study systems are diverse, from microbes and their phage, through interactions in insects, wild rodent communities in the UK and abroad, to the microbes in the cystic fibrosis lung. To better understand the ecological and evolutionary behaviour of these systems, we employ field, genetic, genomic and mathematical approaches. Evolution has traditionally been studied at the level of the phenotype. With the emergence of new genomic technologies, we have an increasing ability to also examine how evolution is reflected in the genome, and to use techniques of molecular ecology to give insights into evolutionary processes. Our current research is trying to understand the molecular basis of adaptation in the peppered moth, and in host-parasite interaction
