Module Title: | Freshwater Ecology |
Language of Instruction: | English |
Teaching & Learning Strategies: |
This module will be delivered via two one-hour lectures and a two-hour practical per week, for fifteen weeks. Students may be required to access teaching material via Blackboard or the student accessible Institute's course specific network folder, in advance of lectures and practicals to encourage active learning. To consolidate lectures and practicals, students will normally be required to carry out assignments, critique and present peer reviewed published case studies, conduct debates on module relevant environmental issues, and take multiple choice question assessments. Group and peer learning will be facilitated during the preparation of assignments, presentations and practicals. Any course-related issue or questions that may arise will be discussed at lectures. Course lecture summaries, course calendar, announcements and other course-related material will be available on Blackboard, a virtual learning environment, or in the student accessible Institute's course specific network folder. Students may then contact the lecturer to discuss formative feedback given on written reports and group project work. On-line demonstrations will illustrate the key concepts of the module and will be available throughout the year. The practical component will
• allow students to develop the required technical competencies, attitudes and behaviours
• develop problem solving abilities and group skills
• promote deep learning via investigation of a problem, application of prior knowledge and analysis of results, thus generating new knowledge
• promote timely submission of reports written in the standard format

Module Aim: |
To provide a theoretical and practical introduction to freshwater and estuarine ecology, and the associated anthropogenic impacts, and to introduce fundamental concepts of ecotoxicology, both theoretical and applied. |
Learning Outcomes |
On successful completion of this module the learner should be able to: |
LO1 |
Define and describe the fundamental principles of freshwater and estuarine ecology. |
LO2 |
Discuss and evaluate the causes and effects of freshwater and estuarine pollution in the global and Irish contexts. |
LO3 |
Employ freshwater quality monitoring and analyse the data. |
LO4 |
Apply and evaluate basic toxicological test procedures and discuss the principles of toxicology and ecotoxicology |

Module Content & Assessment
Indicative Content |
Freshwater Ecology
Basic concepts of ecology and limnology: the ecosystem, populations and communities, ecological niches, energetics and food webs, the role of micro-organisms in the carbon and nitrogen cycles. Properties of water. The hydrological cycle and classification of natural waters. Ecological characterisation of rivers and lakes. Biochemical and physico-chemical aspects of water pollution. Plant and animal communities of lotic and lentic waters. Macroinvertebrates as biotic indices of eutrophication. Contemporary aquatic pollution in Ireland.
Review of marine and brackish water flora and fauna.
Classification of estuaries. Physicochemical characteristics of estuaries incorporating salinity, temperature, dissolved oxygen, wave action, currents, turbidity, substratum. Adaptations of estuarine organisms: morphological, physiological and behavioural. Ecology and effects of pollution on estuaries.
Ecotoxicology: general principles of toxicology and ecotoxicology. Assessment parameters: LD50, EC50, NOEC, LOEC, etc. Toxicity tests: freshwater invertebrates, Eisenia fetida, algae, salmonids, collembola, oribatid mites, nematodes and other test models. Multispecies test systems. Sublethal toxicity tests. Heavy Metals. Pesticides. Oil pollution. Bioaccumulation. Bioprobes and Biosensors. The Microtox system.
|
Practical Work
Practicals will take the form of mini projects where appropriate. Health and safety will be an integral part of all practicals.
Identification of macroinvertebrates by F.B.A. keys. A field trip will take place for quantitative sampling of the aquatic flora and fauna at different stations in a river. Field measurement of temperature, pH, dissolved oxygen, turbidity, conductivity, flow rate, biochemical oxidation demand. Analysis, interpretation and presentation of data. Examination and identification of selected marine/estuarine flora and fauna. Toxicology tests with Daphnia magna, Eisenia fetida, and Steinernema feltiae, as appropriate.
