PhD in avian foraging behaviour and ecotoxicology

NERC funded CASE PhD in the Environment Department at the University of York

Title: Exposure risk and effects of neonicotinoid insecticides to farmland birds.

More intensive arable and animal farming require ever increasing amounts of pesticides to maintain productivity. The sustainable use of pesticides is vital if we are to maintain ecosystem services (e.g. clean water, biodiversity, recreational and spiritual benefits from charismatic wildlife). Evidence is accumulating that the widespread prophylactic usage of NN insecticides is having a variety of unexpected impacts on non-target organisms and ecosystem services. Neonicotinoids (NNs), the world’s most widely used insecticides are believed to harm bees and other pollinating insects. This has led to a two-year EU suspension on three NN products began at the end of 2013. However, NNs are still used as a seed dressing for crops such as cereals and beet.

Recent research has suggested a link between the use of NNs and declines in numbers of farmland birds. However, the research only looks at associations at a large spatial scale with no evidence for the mechanisms involved. Direct toxic effects on birds are possible i.e. consumption of feeds coated with NNs and/or consumption of plants or insects that have taken up NNs. This might result in death or reduced reproduction but also non-lethal effects such as changes in health foraging behavior that will affect fitness. This project will integrate field, lab and aviary studies to determine whether NNs can move through the food chain exposing birds to lethal or sublethal concentrations. In addition, the student will experimentally manipulate exposure to NNs to determine whether NNs cause changes in the behaviour, physiology or health of birds. 

The Royal Society for the Protection of Birds (RSPB) are CASE partners for this studentship, as it links in with their long-term ambition to reverse farmland bird declines population declines.  The RSPB will provide field support and student supervision for this project. This project will suit a student wishing to work in applied ecology and conservation. Experience in fieldwork, particularly with birds will be an advantage.

This project is part of the NERC Doctoral Training Partnership in Adapting to the Challenges of a Changing Environment (ACCE) and  will be supervised by Dr Kathryn Arnold (York), Professor Richard Shore (CEH), Professor Colin Brown (York)  & Dr Will Peach (RSPB).
The project will start Oct 2015 and is competitively funded. UK/EU students only.
