Semesters
Semester 1 Credit Value: 10
ECTS Credits: 5.0

Aims

To develop an in-depth understanding of:
1. The functioning of terrestrial ecosystems and the factors that underpin ecosystem processes and biogeochemical cycling among biomes.
2. Ecosystems as complex, integrated systems with interactions and interdependencies among their biotic and abiotic components.
3. The role of functional biodiversity in modulating pools and fluxes of the major elements.
4. The role of terrestrial ecosystems in biogeochemical cycling at local, regional and global scales.
5. How external forcings (e.g. climate change, anthropogenic interventions, disturbance) impact ecosystem processes and feedback to influence global biogeochemical cycles.

Outline Of Syllabus

Topics are introduced in lectures and explored in greater depth in tutorials, workshops, practicals and field classes. Key topics include:
• Terrestrial carbon, nitrogen and phosphorus cycles
• The role of state factors (i.e. time, climate, parent material, topography, biota) in shaping ecosystem structure, function and development through space and time
• Primary production and its controls; introduction to plant physiological ecology and plant-soil interactions
• Soils and sediments; pedogenesis; the surface chemistry of soils and sediments (e.g. ion exchange, adsorption, hydrophobic interactions, points of zero charge, pH, redox potential); the organic chemistry of soils
• Microbial ecology; role of microbes in catalysing key components of the carbon, nitrogen and phosphorus cycles; rhizosphere processes; mutualisms; role of syntrophy and microbial consortia in metabolism of complex substrates
• Role of trophic processes in regulating ecosystem structure and function
• Effects of climate change and anthropogenic interventions on ecosystem processes and biogeochemical cycling
• Knowledge gaps and unknowns in ecosystem ecology, including critical analysis of the current literature

Teaching Rationale And Relationship

Lectures introduce key knowledge and flag the syllabus and appropriate reading.

Tutorials allow students to work in groups to understand the functioning of terrestrial ecosystems, read and understand the current literature, analyse data (e.g. interpreting graphs or other data products), or develop their problem solving skills.

Computer practicals develop the students’ numerical and data analysis skills. Laboratory practicals introduce techniques in characterisation of plant and soil samples; physical, chemical and biological techniques for quantifying biogeochemical pools and fluxes, and develop laboratory skills.

Fieldwork serves to integrate the module learning outcomes by providing the opportunity to observe, handle and sample environmental samples from selected terrestrial environments.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Description Semester When Set Percentage Comment
Written exercise1M100Students must write a short research essay (1500-2000 words) on a current issue in ecosystem ecology
Assessment Rationale And Relationship

The continuous assessment tests the students' ability to conduct independent research, assimilate and synthesise the broad body of knowledge and understanding developed through the lectures, reading and guided learning activities. It also develops and tests the students' ability to analyse and assess the peer-reviewed literature, identifying major knowledge gaps and the limitations of the current research. Development of these higher order skills and knowledge will be supported through the guided learning activities and small group activities, including targeted workshops explicitly designed to develop the students' critical abilities.
