PL5303: ECOSYSTEM PROCESSES (2015-2016)

Last modified: 25 Mar 2016 11:37


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.

Course Description

Course Aims: To understand the main biological, chemical and physical processes involved in the conversion of energy and other resources. The emphasis is on being able to relate measurements made at local scales to understand their relevance for global processes. Content: Primary production (Carbon cycle; Biomes; Scaling from leaf to biome). Water use (Water cycle; Coupling between vegetation and atmosphere; Soil water; Water use efficiency). Soil microbiology & organic matter decomposition (Decomposers; Soil respiration; Root-microbe relations). Nutrient acquisition by plants (Nutrient demand; Nutrients in soil; Nutrient supply; Soil heterogeneity; Nutrient use efficiency). Secondary production (Grazing effects; Energy and resource flow between trophic levels). Ecosystem sustainability, human impacts and feedbacks.

Associated Costs

None
