Mark is an ecologist researching environmental change in freshwaters. His research group is focused on understanding how environmental stressors and climate change, especially extreme climatic events such as floods, droughts and heat waves, affect the structure and functioning of aquatic ecosystems. His group works empirically across a range of spatial and temporal scales, from laboratory microcosms to natural environmental gradients in real ecosystems, and has developed new state-of-the-art mesocosm facilities which enable novel interdisciplinary experimental approaches to be applied in areas of water science usually characterised by phenomenological study. Mark currently leads several NERC-funded research projects and supports a number of doctoral researchers and postdoctoral fellows. He also works actively with a growing network of colleagues in the UK and overseas.

Teaching

Mark has developed a broad teaching portfolio across the Geography and Environmental Science programmes, at both undergraduate and postgraduate levels. He teaches in the following areas:

  • Tutorials and fieldwork
  • Ecological systems
  • Techniques in physical geography
  • Research methods for dissertations
  • River ecology
  • Advances in water science
  • Research and management of rivers
  • River environmental management dissertation
  • Research project supervision
  • Freshwater environments

Postgraduate supervision

Mark Ledger鈥檚 research in freshwater systems encompasses community ecology, biodiversity and environmental change. His research group works at a range of spatial and temporal scales, utilising laboratory microcosms, field mesocosms and natural environmental gradients in real ecosystems. Their current research has four overlapping foci: disturbance ecology; food webs, species interactions, particularly plant-herbivore dynamics, and stressor effects on biodiversity and ecosystem function. Ongoing research includes:

Disturbance, biological legacies and community development
Disturbance and dynamic stability
Environmental change and freshwater food webs
Model food webs: replicability and realism
Interaction strengths within the algae-herbivore sub-web
Environmental change, aquatic biodiversity and species interactions

He welcomes enquiries from prospective students in these areas.
