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, management interventions, disturbance) impact ecosystem processes and feedback and influence global biogeochemical cycles.
6. The applications of ecosystem science to the sustainable management of human production systems, including agriculture, forestry and bioenergy crops.
7. The ecological basis of nature-based climate solutions.
Outline Of Syllabus
Topics are introduced in lectures and explored in greater depth in 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.
• The role of innovations in land-use and land management practices for climate action and sustainable land management.
• Knowledge gaps and unknowns in ecosystem ecology, including critical analysis of the current literature.

| Scheduled Learning And Teaching Activities | Fieldwork | 1 | 5:00 | 5:00 | Present in person in the field |
| Total | 100:00 |
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. Students undertake a range of activities that develop their numeracy, data analysis and interpretation skills, capacity for knowledge synthesis and critical analysis. This includes quantitative data analysis and data interpretation exercises, critical discussions of the peer-review literature, and essay writing support (e.g. preparation of an essay outline in support for the summative assessment).
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
Other Assessment
| Description | Semester | When Set | Percentage | Comment |
|---|---|---|---|---|
| Essay | 1 | M | 70 | Students must write one short critical essay (i.e. approximately 1000 words) on the topic of carbon cycling in terrestrial ecosystems. |
| Written exercise | 1 | M | 30 | Students must write a newspaper article (i.e. approximately 1000 words) |
Formative Assessments
Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.
| Description | Semester | When Set | Comment |
|---|---|---|---|
| Written exercise | 1 | M | Preparation of an essay plan to help students prepare for the summative assessment. |
Assessment Rationale And Relationship
The summative assessments consists of 1 essay that examines the students' knowledge and understanding of the broad themes covered in the module. The summative assessment develop and test the students' ability to conduct independent research, assimilate and synthesise the broad body of knowledge obtained through the lectures, reading, and guided learning activities. They also develop and test the students' ability to critically analyse data and information from the peer-reviewed literature.
The newspaper article will encourage students to develop general science communication skills.
Development of these higher order skills will be supported through guided learning and small group activities, including targeted workshops designed to develop the students' critical abilities. The students will undertake a formative assessment (i.e. Written exercise 1) towards the end of the semester, where they prepare an essay plan for the critique of a peer-reviewed paper, further developing their writing and communication skills.
