GEOGG074 Lakes

OPTION COURSE GEOGG074 - LAKES (15 credits)
(15 credits; Term 2)

Staff:
Carl Sayer, Ewan Shilland, Helen Bennion, Roger Wotton, Rick Battarbee, Ian Patmore, Emma Wiik, Chris Curtis, Suzanne McGowan (Nottingham University), John Anderson (Loughborough University), Stewart Clarke (Natural England)

Aims:
to provide an introduction to lakes and ponds and their catchments
to provide an understanding of ecosystem structure and function in lakes and ponds
to highlight key approaches in the management and conservation of lakes and ponds and the legislative drivers that underpin this work.

Content:
This course aims to develop a holistic understanding of lakes and ponds and their place in the landscape. Different lake and pond types and key environmental gradients are introduced. The focus then shifts to the nature of lake-catchment systems. Hydrological and physical physico-chemical processes and the effects of geographical, geological and climate settings on these are covered. The structure and functioning of biological communities within lake systems and the natural and anthropogenic stresses affecting these are described, and the importance of lake-catchment systems to conservation and management is explored. A field class introduces sampling in lakes and practical classes provide taxonomic and numerical analysis skills.

The following specific topics are covered:
·    Introduction to lakes and ponds and their different origins
·    Lake-catchment interactions
·    Hydrological and physical processes
·    Lake chemistry
·    Primary production and food-webs
·    Ponds ecosystems and their conservation
·    Disturbance of lake-catchment systems, conservation, restoration and management

Assessment:
Site review and management plan for a case study lake (worth 8% of total assessment)

Format:
The course is based upon lectures, seminars, practical classes and fieldwork

Learning outcomes:
At the end of the course the student should:
understand the diverse nature of lakes and pond ecosystems
be able to conceptualise the integrated nature of lake - catchment systems and
appreciate the interrelationships between hydrological, physical and chemical processes operating within the lake - catchment systems.
understand the nature of ecosystem structure and function in lakes and ponds
have a good knowledge of practical lake sampling approaches and numerical analysis techniques that can be used to classify lakes for conservation purposes
have an awareness of the problems posed by human impacts on lakes and ponds and how these can be addressed by conservation and management approaches
