| Option A - Analysing Marine Ecosystems
The objectives of this option can only be achieved satisfactorily if it is taught by means of a substantial amount of fleld work. A.1.1-- 1 List the variable physical factors of a marine ecosystem.
A.1.2-- 2,3 Describe and evaluate methods for measuring at least 3 physical variables within a marine system.
A.2.1-- 2 Construct simple keys and use published keys for the identification of marine organisms. Students could practise with keys supplied and construct their own key for up to 12 species.
A.2.2 --2,3 Describe and use methods for estimating abundance of marine organisms (including mark/release /recapture, quadrat and percentage frequency, population density and percentage cover), and state the limitations of the methods.
See the Lab on Plankton Diversity&Density in Pedder Bay A.2.3-- 2,3 Describe and evaluate methods for estimating biomass of trophic levels in a marine community. Dry weight measurements of quantitative samples could be extrapolated to estimate total biomasses. A.2.4 --1 Define the term diversity. A.2.5-- 2 Describe how a named diversity index is used.
A.s Obj. A.3 Measuring productivity of the system (3h) A.3.1-- 2,3 Describe and evaluate a method for measuring gross and net primary productivity in a marine ecosystem. See the references on productivity: SeaWiFS--http://seawifs.gsfc.nasa.gov/SEAWIFS/BACKGROUND/SEAWIFS_BACKGROUND.html A3.2-- 2,3 Describe and evaluate a method for measuring gross and net secondary productivity in a marine system.
Obj A.4 Measuring changes in the system (3h)
A.4.1-- 2,3 Describe and evaluate methods for measuring changes in abiotic and biotic components of a marine system along an environmental gradient or over time.
A.4.2-- 2 Describe methods for assessing changes in abiotic and biotic components of a marine system due to a specific human activity. A.4.3-- 3 Describe and explain changes that might be found by these studies. Obj A.5 Comparative study of ecosystems (5h) A.5.1-- I State the physical characteristics of two different marine ecosystems. Marine systems to be selected from: pelagic, neritic, bathyal, littoral, mangroves and coral reefs. A.5.2-- 2 Describe the inter-relationships of these physical characteristics. A.5.3-- 2 Describe the overall community structure and functioning of each of the two marine ecosystems. A.5.4 3 Compare the community structure and functioning of each of the two systems, relating differences to the physical characteristics. |
