This fully funded PhD project at the University of Bristol investigates the impact of regenerative agriculture (RA) on pollinator populations, with a particular focus on bumblebees. Agriculture dominates UK land use, and intensive practices have contributed to biodiversity loss and increased greenhouse gas emissions. RA is a farmer-led movement aiming to restore soil health, biodiversity, and water quality while maintaining sustainable yields. Despite its growing popularity, there is limited data on how RA affects biodiversity, especially pollinators like bumblebees, which are vital for food production and wildflower pollination but are experiencing population declines. The project will compare bumblebee health on conventional farms and those using RA practices, aiming to determine population and colony-level responses and understand how specific management practices influence pollinators. Research methods include field work, genetic analysis using tarsal clippings, and quantitative analysis. The candidate will gain skills in experimental design, ecological surveying, genetic analysis, statistical modelling, GIS, and scientific writing. Supervision is provided by Dr Harry Siviter and Prof Jane Memmott, with collaboration from the Bumblebee Conservation Trust, including a work placement tailored to the student's skills and interests. The data generated will inform future policy statements. The SWBio DTP supports students from diverse backgrounds, offering reasonable project adaptations and flexible study options. The programme provides interdisciplinary bioscience training and access to extensive scientific networks and facilities. Funding covers a four-year studentship, annual stipend (£20,780 for 2025/26), tuition fees, research costs, fieldwork, conferences, and a three-month placement, with allowances for sick and parental leave. Up to 30% of studentships are available for international applicants. Applications are open until December 3, 2025.
