The Centre for Ecology and Hydrology

CEH is a component of the Natural Environment Research Council and the UK’s Centre of Excellence for integrated research in terrestrial and freshwater ecosystems and their interaction with the atmosphere. CEH carry out both long-term and large-scale analyses of freshwater responses to multiple stressors including the unique long-term data on the Cumbrian lakes and Loch Leven.

The Lake Ecosystems Group at Lancaster:

Prof. Stephen Maberly (CEH, PI)

SM CEHStephen is a limnologist & ecophysiologist of aquatic algae and plants with a particular interest in relating changing environmental conditions, particularly those driven by climate change, to physiological and ecological responses through laboratory experiments, field measurements, use of novel techniques and the analysis of long-term environmental data. He has a particular interest in changing CO2 availability in water and the effects this has on ecology of algae and plants. @StephenMaberly

Dr Stephen Thackeray

ST cehStephen is a lake ecologist at CEH with three broad research interests; the responses of lake ecosystems to environmental change (resolving how stressors such as climate change and nutrient enrichment impact upon the ecology of freshwater lakes), zooplankton ecology (spatial structuring and community composition) & phenological change in freshwater communities… and beyond. Stephan led a UK-scale assessment of shifts in the seasons, and a follow-up project on climatic drivers of these changes. @SteveThackeray



Dr Ian WinfieldIW ceh

Ian is a Freshwater Ecologist. He works within the Lake Ecosystems Group of CEH, with over 28 years of research experience encompassing diverse areas of freshwater fish ecology. Ian has a particular interest in population and community dynamics, including interactions with non-native species, roles in lake ecosystems, effects of climate change, the use of hydroacoustics for studies of fish and their habitats, and the applied issues of the conservation of biodiversity and fisheries management. @ianjwinfield


Freshwater Ecology Group at Edinburgh:

Dr Laurence Carvalho

LC cehLaurence is an ecologist with more than 25 years experience investigating water quality and the ecological health of freshwater ecosystems, particularly in response to nutrient enrichment and climate change.  He has worked on a wide range of aspects of the impact of nutrients on freshwaters, including: the effect on water quality and the frequency and magnitude of harmful algal blooms. With over 60 peer-review papers (h-index 22, >1800 citations) and a number of popular articles, Laurence was involved in developing UK and European environmental standards and bio-assessment schemes for the EC Water Framework Directive. Laurence recently spent one year on secondment to the European Commission developing indicators of ecosystem functioning and services for freshwaters. @LacLaurence

LM cehDr Linda May

Linda is the project manager at Loch Leven and main research areas are the causes, effects and remediation of lake eutrophication.



Dr Bryan SpearsBS ceh

Bryan is a freshwater ecologist with an interest in biogeochemical processes and ecological resilience in lakes. Currently, his research is focussed on the control of legacy pollution in lake bed sediments using geo-engineering. This research is designed to develop our ability to manage freshwater resources more effectively. Click here to find out more about CEH research on lake restoration:


Dr Dan Chapman

Dan is a plant ecologist modelling the spread of invasive and pest speciesHe leads projects modelling the dispersal, spread and impacts of alien invasive plants and pest organisms. These models are important in evaluating the socio-economic costs of invasion and in planning effective control strategies. Dan is also interested in modelling large scale patterns in phenological change. This is often driven by temperature and so phenological change is a key indicator of the impacts of climate change on biodiversity.
