Professor Alison M. Dunn

Profile

My first degree was in Zoology at Pembroke College Oxford. After working as a Nature Research Warden, a Lab Technician and a Violin Teacher, I returned to academia to undertake a PhD in Parasitic Sex Ratio Distorters (parasites that alter the sex of their hosts) at the University of Leeds. My post doctoral research was at the NERC Centre for Population Biology, Imperial College. I came to the University of Leeds as a NERC Research Fellow, then as a University Research Fellow, before joining the academic staff. Currently I am Professor of Ecology in the School of Biology working on Invasive Species and Wildlife Diseases.

Research interests

Invasive Species, Parasitic Disease and Novel Ecosystems

Invasive Alien Species lead to novel trophic and competitive interactions. These novel interactions can lead to population extinctions, changes in community structure and in ecosystem function.  Our lab studies the impact of invasive predators on native species and ecosystems. Parasites are also important players in these novel interactions. Invasive species can bring parasites with them; novel weapons that can infect native species. Parasites can themselves be biological invaders with the potential to lead to emerging infectious diseases. We are interested in the outcome of these novel interactions, in predicting and reducing the risk of disease emergence.

Parasites and host behaviour. Parasitic diseases are ubiquitous in wildlife. Interactions between competitors, predators and their prey have long been viewed as the foundation of community structure. But parasites – long ignored in community ecology- are now recognised as playing an important part in influencing species interactions. Parasites reduce the fitness and survival of their hosts. But we are particularly interested in how parasites drive changes in host behaviour and life history (trait mediated effects), how this in turn affects competitive, predator-prey and other consumer-resource interactions, and the outcome for community structure and ecosystem function.

Preventing the Spread of Invasive Non Native Species

We collaborative with environment managers to translate research evidence into on the ground solutions. Invasive Alien Species (IAS) are a leading cause of biodiversity loss, and threaten ecosystem services with spiralling economic costs. For example, zebra mussels block water pipes, crayfish plague threatens our native crayfish, floating pennywort can lead to flooding. Freshwaters ecosystems are particularly vulnerable to the spread of IAS through trade, transport, recreation and environmental management. Once IAS become established it is often difficult and expensive to manage them. Biosecurity is a critical first line of defence to prevent their introduction and spread. We are researching effective, practical biosecurity practices for application in a range of field conditions. We work with stakeholders to identify barriers to biosecurity, increase awareness and uptake of biosecurity across diverse sectors.

Working with industry to slow the spread of invasive species

Water companies provide a constant supply of safe drinking water to homes and businesses, and transfer of water (eg between lakes or reservoirs) is essential to ensuring water supplies. Accidental translocation of animals or plant fragments during water transfers can lead to the spread of Invasive species. In collaboration with Civil Engineering, and with Yorkshire Water, we are bringing multidisciplinary approaches to develop and test new mitigation practices to reduce the spread of invasive non native species during the large scale transfers needed to secure water supplies, focussing on key aquatic animal and plant INNS identified by the EA and the UK water industry.

Extinction, Invasions and Parasites

Extinction is one of the great challenges of our times. Conversely, parasite control campaigns may be considered managed extinctions. In collaboration with the Schools of English, History, Philosophy and the Sustainibility Research Institute we are exploring parasite extinction and conservation as well as the impact of conservation and biodiversity loss on the wellbeing of those involved in conservation.
