Personal profile


Peter joined the research and teaching staff of Aberystwyth University in September 2006 and is part of the DoLS Ecology Group. Research interests include the "Ecology of Grazed Ecosystems (montane, upland and lowland wetland habitats)", "Monitoring and assessment of biodiversity in a changing environment" and "Environmental and management drivers of soil chemistry and vegetation dynamics in the uplands". Peter contributes to teaching of IBERS undergraduate and postgraduate students, a Postgraduate Certificate of Teaching in Higher Education was conferred and a Fellowship of the Higher Education Academy awarded in 2009. Served for two years as Senior tutor for Part Two undergraduates.

Research interests

Research interests within the DoLS Ecology Group include:

  • Ecology of grazed ecosystems (montane and upland semi-natural habitats):
    • Grazing impacts on montane and upland food webs and wildlife
    • Development of biodiversity indicators for low-input
    • European farming systems
  • Monitoring and assessment of biodiversity in a changing environment
    • Long Term Ecosystem Research networks
    • Biodiversity and ecosystem processes (services) in the uplands and mountains
    • Environmental and management drivers of soil chemistry and vegetation dynamics in the uplands.

Currently serves on the Ecosystem Functioning Working Group of GEO BON (Earth Observation - Biodiversity). Served as Secretary of the UK Biodiversity Science Committee 2012-16, the Welsh Biodiversity Partnership, Upland Ecosystem Group; the steering committee of the Environmental Change Network, Snowdon monitoring site for Natural Resources Wales. Recent projects have focused on the selection of biodiversity indicators as measures of the sustainability of farming (EU BioBio), and most recently collaborative research has aimed to integrate biodiversity into environmental impact measures, to include with social and economic measures within Life Cycle Analyses of a healthy diet (Expert advisor to Defra project “Evidence to define the sustainability of a healthy diet”, Defra and Institute of Food Research, December 2010 to July 2011) and in organic dairy production across Europe (Co-I on EU SOLID project). PD previously served as a Senior PDRS at the Macaulay Institute where he was a Wildlife and Landscape Ecologist. He was the scientific co-ordinator of the five year “GRUB” research project. This research addressed long-term ecological effects of changes in upland farming, with emphasis on factors affecting the breeding success of insectivorous birds. He also oversaw the biological monitoring of two of the UK ECN sites in Scotland.
