The Ecology and Environment Research Group (EERG)

Research Lead: Dr Duncan Westbury

Bumblebee on Cornflower

The Ecology and Environment Research Group (EERG) focuses on two complementary research themes, the delivery of Ecosystem Services within the farmed environment and Wildlife Management.

Members of EERG continue to develop research programmes that not only bring about significant environmental benefits, but also benefits that have cultural, economic and societal impact. This is achieved through engagement with local and national stakeholders and the promotion of knowledge exchange. EERG actively encourages national and international collaborations to further its research and increase impacts.

Ecosystem Service Delivery

Ecosystem Service Delivery

Wildflower strip in an apple orchardAgricultural intensification has been highly effective at increasing food production, but this has been coupled with land use change and the loss of semi-natural habitat. Consequently, there is now an imbalance in the ecosystem services required to support production.

For example, due to habitat loss within agricultural landscapes, farmers are becoming increasingly reliant on the use of managed pollinators (including honey bees, solitary bees, and bumblebees) and Plant Protection Products (PPPs) to increase yields. However, these approaches are not deemed sustainable as they fail to address the underlying drivers of change. Changes in land use have also increased impacts on water resources, in part due to a reduction in the capacity of ecosystems to buffer the extensive use of agrochemical inputs.

Investigations into the development of approaches that underpin the delivery of ecosystems services in the farmed environment is a key area of research for EERG. It is evident that the appropriate management of agricultural landscapes and the strategic deployment of habitat interventions has the potential to deliver multiple ecosystem services whilst promoting sustainable intensification and therefore food security. We aim to develop evidence-based solutions to support agricultural production.

Current Research Activities

Dr Westbury is also supervising PhD student Charlotte Selvey at University College London, as a member of the thesis committee board. Charlotte is investigating the risks of biodiversity loss in PepsiCo's agricultural supply chains. Two PhD studentships have recently started, with Zeus Mateos Fierro studying pollination and pest regulation in UK cherry orchards, and Alice Mockford studying pest regulation by natural enemies in Spanish orange groves.

Wildlife Management

Wildlife Management

The research theme is focused on the conservation and management of species and their interactions with the environment. This theme includes a number of research strands:

i) Habitat and species management for conservation

ii) The management of problematic species and their impacts.

iii) The use and development of eDNA techniques for the detection and monitoring of notable species in freshwater habitats.

Current Research Activities

Bumblebee populations have declined dramatically in the UK in recent years, with two species going extinct since 1940. Such impacts have mainly been driven by changes in agricultural practice. To help address the increased concern for bumblebee populations, Dr Ashbrook’s research focuses on the use of modelling approaches to inform conservation management. She is currently working with Dr Richard Comont from the Bumblebee Conservation Trust to develop species distribution models, which will be used to inform targeted habitat management. New monitoring techniques for bumblebees are also being developed to quantify flower visitation and the use and availability of pollen resources.

Dr Ashbrook is also providing information for evidence-based conservation management to help secure the survival of vulnerable bee species. These include the previously-extinct Bombus subterraneus (short-haired bumblebee) and Bombus sylvarum (shrill carder bumblebee), which is threatened with extinction in the near future. Dr Ashbrook is also interested in the value of using biological records submitted by members of the public to produce high quality datasets for distribution modelling.

Dr Dutton is investigating wild boar ecology and human interactions/conflicts. In addition, he is also studying aspects of rabbit management with Worcestershire Wildlife Trust, and has recently completed a “Bat flyways” project with Natural England.

Great crested newt moving through grassMRes students are also conducting research under this theme. Dominique Cragg is currently studying habitat selection by corn buntings (Emberiza calandra) with supervision by Drs Wheeler and Dutton, whilst Anna Brohan is investigating the value of corridors for the movement of great crested newts (Triturus cristatus) (supervised by Drs Dutton and Westbury).

Following a preliminary study with an undergraduate student, Dr Wheeler is now developing eDNA techniques to assess crayfish populations and the presence of crayfish pathogens within the Wyre Forest National Nature Reserve. Investigations also continue with Dr Westbury into reptile predation by pheasants using eDNA approaches with pheasant scat, in collaboration with the Game and Wildlife Conservation Trust (GWCT), and the Amphibian and Reptile Conservation Trust (ARC trust).
