BIO3210EN - River & Lake Biology

Course description

Although only 1% of the Earths's water is fresh, freshwater ecology is very fundamental. This course focuses on five aspects of Freshwater ecology. (1) Fundamentals of the origin and age of rivers and lakes, lake morphometry and river and lake catchment properties. (2) Focus on te physicochemical parameters of aquatic systems, as well as the underlying concepts. (3) River and lake biotics, such as phytoplankton, zooplankton, macroinvertebrates, etc, in running and standing waters. (4) The inter-relationship between both biotic and abiotic aspects of these water bodies; addressed in the context of food web interactions. Emphasis will be laid on shallow lakes and concepts of cascading trophic interactions, alternative stable states, niche shifts, succession, and trophic concepts. (5) Finally, discussion on the effect of anthropogenic pressure on these systems would be made in the light of contamination and eutrophication; Concepts of biomonitoring, restoration, rehabilitation, and biomanipulation will also be discussed as part of remediation efforts

How this course benefits students

Students will be able to (1) form an idea of the diversity of the chemical composition of aquatic ecosystems and of the origin of different classifications

Why this course is important

The link between fresh water and salt sater and ground water highlights the relevance of studying the composition and health of these water bodies.

How this course relates to missional core values

Biblically based

(2) explain the main processes of a lake as an ecosystem as a function of seasonal variations and vertical gradients

Missionally driven

(3) place the trophic status of 'stationary waters' in the broader context of their evolution

Contextually informed

amongst others

Interculturally focused

This course will attract every students efforts towards our christian obligation to protect our environment

Practically minded

Missionary biologists are to tend and care for all live forms and the environment we live in

Experientially transformed

rather than participate in its degradation.
