AQ 326 Ecology of Inland Waters (3 units)
\r\nObjectives:
At the end of the course, the student should be able to:

\r\n• Classify and describe different inland water habitats and ecosystems, and abiotic and biotic factors that operate in them.

\r\n• Identify principal inland water flora and fauna and factors affecting their abundance, distribution and production.

\r\n• To introduce students to the various human impacts on freshwater and how management of catchment basis can be achieved.

\r\n\r\nSynopsis
\r\n(i) Introduction to inland water ecosystems: Rivers and lakes-their distribution, origins, forms and lakes succession. Distribution and abundance of water; the hydrological cycle. Water as a habitat. Shallow lakes and ponds-origins and distribution, characteristics, invasion and growth of macrophytes, shifts between macrophyte and Phytoplankton dominance. Resevoirs and swamps. The ontogeny of inland aquatic ecosystems.

\r\n(ii) Physical and chemical properties of water: Temperature and heat budgets, density, light turbidity and water colour. Thermal stratification and mixing in lakes. Water movements in lakes-waves, seiches, currents, pH, acidity/alkalinity, salinity and dissolved gases.

\r\n(iii) Biogeochemical cycles and nutrient eutrophication: Nitrogen, Phosphorus, Sulfur, Iron, Sulfur and Silica cycles. Nutrient and eutrophication.

\r\n(iv) Freshwater biotic communities and management of catchments, Factors affecting distribution and abundance of freshwater flora and fauna, Planktonic communities. Zooplankton and their interactions with fish. Adaptations of aquatic inland waters biotic communities. Exotic species. Human impacts on inland water systems. Management of watershed. Restoration of aquatic ecosystems.\r\n\r\n

AQ 221 Estuarine and Wetland Ecology (3 units) \r\n

\r\nObjectives:
To introduce students to estuarine and wetland environments, with their accompanying physical, chemical and biological characteristics. Learn how humans impact estuaries and wetlands and their importance to humans’ well being.\r\nSynopsis:
