PL3304: ECOSYSTEM PROCESSES (2015-2016)

Last modified: 25 Mar 2016 11:34


Course Overview

Terrestrial ecosystems play a pivotal role in modulating the fluxes of energy and matter at the Earth’s surface, including the cycling of carbon, nutrients and greenhouse gases. Understanding the structure and function of terrestrial ecosystems is critical for understanding environmental challenges such as global warming, biodiversity loss, sustainable development and pollution. This course develops principles of systems ecology and biogeochemistry, focusing on the fundamental role played by living things in regulating key ecosystem processes such as carbon cycling, nitrogen dynamics, trophic transfers, and land-atmosphere exchange of greenhouse gases.

Summative Assessments

1st Attempt: Written exam (67%) and continuous assessment (33%), continuous assessment is a worksheet based on data collected in the practical classes. Resit: Similar to 1st attempt, with continuous assessment mark(s) and /or exam mark carried forward with an opportunity to resit either or both, depending on what was failed in the first attempt.

Formative Assessment

A strong emphasis will be made throughout the course on informal verbal feedback during practicals and workshop sessions.

Feedback

Each student will receive individual feedback and a mark for each task. Feedback will be provided as written comments. Groups will also be given generic feedback.
