Prof. Stephen C. Maberly

SMaberlyBrief description of general interest: I am an aquatic ecologist with an interest in a mechanistic understanding of how lakes and their inhabitants function and are affected by external pressures such as nutrient-availability, climate change and altered trophic interactions. My prime interest is in the ecophysiology of phytoplankton and freshwater macrophytes. I have been working in the English Lake District for over 20 years and lead CEH’s long-term monitoring work there.
 
Specific role in this project: I am the lead Principal investigator on this project and, in addition to managing the project, will be involved in determining the cause of the recent summer increase in phytoplankton.
 

 Dr Jonathan Grey

jgreyBrief description of general interest: I am an aquatic ecologist with diverse interests but which are united by the common application of stable isotope techniques to answer ecological questions. My primary interests include: the importance of cross-boundary energy subsidies between aquatic and terrestrial ecosystems; tracing novel energy resource use (e.g. methane) through food webs; and how invasive species interact, not only with native species, but also with other invaders, mediated via diet. Now a Senior Lecturer in Freshwater Biology at Queen Mary, University of London, I have worked on various lakes in the English Lake District, and particularly Esthwaite Water, for the past 15 years.
 
Specific role in this project: I am the Lead Investigator from Queen Mary on this project and, in addition to helping Stephen Maberly manage the project overall, will work closely with Peter Smyntek overseeing the stable isotope work. This will be used to determine trophic interactions between the native and invasive fish species in both space and time, as well as to characterise dietary overlap and ecosystem functioning.

Dr Ian J. Winfield

iwinfieldBrief description of general interest: The ecology and management of freshwater fish using a broad, integrative approach. Although such work is conducted throughout the UK and overseas, a large component of it involves the continuation of long-term netting and trapping studies of Arctic charr, perch and pike in Windermere. This work is augmented by the use of state-of-the-art hydroacoustics to investigate fish abundance, distribution and size structure.
 
Specific role in this project: I am a Co-I on the project. I will provide and analyse appropriate components of the Windermere long-term fish population data, with particular focus on the winter diet of pike and their spatial distribution using hydroacoustics. The latter data source will also be analysed to provide an indication of long-term trends in the abundance and prey consumption of planktivorous fish.
 

 Dr Alex Elliott

aelliottBrief description of general interest: I am a Lake Ecosystem Modeller based at the Centre for Ecology and Hydrology, Lancaster. My role is to examine various aspects of phytoplankton community assembly, including species succession and the effects of disturbance events. To assist in this task, I use the PROTECH (Phytoplankton RespOnses To Environmental CHange) model, which simulates the growth of multiple algal species in lakes and reservoirs. I have being working with the model for over 10 years and have published over 35 papers.
 
Specific role in this project: I will be coordinating the phytoplankton modelling in the project as well as developing and testing the roach modelling.
 

 Dr Heidrun Feuchtmayr

hfeuchtmayrBrief description of general interest: My major research interest isplankton and their interactions within a food web as well as responses of lakes to a changing environment. Besides my scientific interest in lake ecology, I also manage long-term freshwater databases.
 
Specific role in this project: Together with my colleagues Peter Smyntek and Stephen Thackeray, my work focuses on the analyses of long-term changes in the phytoplankton and zooplankton community of Windermere as a response to changes in the food web. In my role as database manager I will also be responsible for data extraction, database maintenance and secure archiving of data generated by this project. 
  

 Dr Ian Jones

ijonesBrief description of general interest: I am a physical limnologist with research interests in the interactions between physics and ecology within lakes and the way in which a changing climate will impact upon lake ecosystems. As well as being a lake modeller I also run the Automatic Water Quality Monitoring System buoys in the English Lake District
 
Specific role in this project: In the project I will work with Steve Thackeray on developing a zooplankton model and with Alex Elliott on using the PROTECH model to study the (two-way) links between changing algal abundance and thermal stratification in Windermere. I will also assess these links by examining the long-term data CEH hold on the temperature profiles in Windermere and the phytoplankton counts for the lake.
 

Dr Peter Smyntek

Brief description of general interest: I am an environmental biogeochemist with broad research interests including the impact of invasive species on freshwater ecosystems and the movement of energy and nutrients through food webs. 
 
Specific role in this project: I will be involved with many aspects of this project, with a particular focus on using stable isotope analysis, an effective natural tracing technique, to evaluate shifts in diet and food web relationships among the fish and zooplankton communities in Windermere. Substantial changes in the food web of Windermere affecting the whole ecosystem may have taken place as a result of the rapid expansion of the non-native fish, the roach over the past 15 years.

 Dr Stephen Thackeray

sthackerayBrief description of general interest: My research interests are, broadly, the effects of long-term environmental change upon lake ecosystems with a specific interest in crustacean zooplankton communities.
 
Specific role in this project: Working with Peter Smyntek and Heidrun Feuchtmayr, I will be involved principally in examining long-term changes in the abundance, species composition and size structure of the Windermere zooplankton community. With Ian Jones, I will also work on developing a zooplankton population model that can be used to help resolve the mechanisms driving the observed changes in the Windermere ecosystem.
