20 credits at level HE6
To investigate the composition of lake and river communities and the ecological relationships of organisms within these communities.
To investigate examples of the exploitation of freshwaters or wetlands in the UK.
To examine the use of organisms for toxicity testing.
To investigate the impacts of pollutants on freshwater ecosystems.
To enhance students' transferable skills, including IT, data interpretation, researching and communication skills.
Pond and lake ecosystems (physical and chemical features, nutrient status, primary production, phytoplankton ecology, resource allocation, community composition and organismal relations, food webs)
Stream and river ecosystems (as above)
Factors affecting trophic relationships (competition models, Lotka-Volterra, Tilman, cascading trophic interactions, case study examples)
Exploitation of freshwaters
Topical applications of freshwater research (assessing water quality, biological monitoring, RIVPACS, River Habitat Survey, effects of impoundments, management of leisure activities).
Biological monitoring and biological indicators of pollution (, the Environment Agency's Water Quality Assessments, and air quality monitoring)
Biological treatments and remediation of pollution (sewage treatment, microbial infallibility, sustainability issues)
Ecological and physiological effects of metals and other inorganics (Case studies on lead, cadmium and mercury. Effects of hydrogen ions, nitrates and phosphates)
Ecological and physiological effects of xenobiotic chemicals (Case studies on oestrogenic compounds, DDT and other pesticides. QSARís)
Toxicity testing (Lethal and sub-lethal toxicity tests, species selection, Microtox methods)
Topics will be introduced by interactive lectures and extended via in-class activities involving small group work. Directed reading will be used to allow students to consolidate their knowledge base and investigate the current research literature.
Use will be made of printed literature, the Internet, CD-ROM's and video material.
The learning time for this module is 200 hours. This will be allocated approximately as follows.
Class contact Lecture and student-centred work 12 x 3 hours = 36 hours
Seminar presentation 1 x 3 hours = 3 hours
Sub-Total = 39 hours
Time in private study not completing assessment items: = 120 hours
Time completing assessments: = 41 hours
Total = 200 hours
when you have successfully completed this module you will:
to demonstrate that you have achieved the learning outcome you will:
|1.||Demonstrate knowledge and understanding of typical assemblages of lake and river communities of their inter-relationships, and of the responses of these communities to pollutants.||
1a) Describe using names examples, typical assemblages and explain the Erophic relationships with these assemblages.
b) Critically evaluate the theories which seek to explain these relationships.
c) Describe, using examples and explain the responses of communities to pollutants.
|2.||Criticallly assess human impacts on freshwater ecosystems||Prepare a case study according to the specification set by the tutor and give a presentation based on this.|
|3.||Evaluate different forms of toxicity tests and analyse the data obtained appropriately.||
3a) Describe alternative methods for carrying toxicity tests
b) Assess these methods and apply the most appropriate to a case study situation identified by the tutor.
Your achievement of the learning outcomes for this module will be tested as follows:
