Slowing the Spread of Invasive Non Native Species

Invasive Non Native Species (INNS) are a leading cause of biodiversity loss and threaten ecosystem services. 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 INNS through trade, transport, recreation and environmental management. Once INNS 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 are also increasing the awareness and uptake of biosecurity across diverse stakeholders.

In collaboration with the Centre for Environment Fisheries and Aquaculture Science, The Environment Agency, Yorkshire Water, Yorkshire Wildlife Trust, Yorkshire Dales National Park Authority, Nidderdale Area of Outstanding Natural Beauty, Natural England, Forestry Commission, National Trust, Yorkshire Dales Rivers Trust, Ribble Rivers Trust, Dales to Vale River Network, Yorkshire Invasive Species Forum (YSIP), Animal and Plant Health Agency (APHA)

Parasites in Ecological Communities

Interactions between competitors, predators and their prey have long been viewed as the foundation of community structure. Parasites – long ignored in community ecology- are now recognised as playing an important part in influencing species interactions. We are particularly interested in the effects that parasites can have on 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.

In collaboration with the Centre for Environment Fisheries and Aquaculture Science, the Centre for Ecology and Hydrology.

Parasites and Biological Invasions

Biological invasions lead to novel ecological interactions between native and invasive species. Parasites are important players in these interactions. Parasites can change the outcome of interactions between native and invasive species; invasive species may lose their parasite; and 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, and in the potential for harnessing diseases for biocontrol.

In collaboration with the Centre for Environment Fisheries and Aquaculture Science, the Centre for Ecology and Hydrology.

Funding for these projects comes from NERC, BBSRC, the University of Leeds and from our project partners. My work involves collaboration across the University of Leeds where I am based in the Ecology and Evolution Research Group. I am also an active member of Water@Leeds and collaborate with staff from the School of Geography and the Sustainability Research Institute.
