Overall aims and purpose
The course aims to provide students with an integrated understanding of the key abiotic and biotic drivers that shape marine communities and habitats. It aspires to give students a framework for understanding the processes that cause marine systems to persist or to change. Drawing on course content and wider degree contents, the intent is that students will pull together their wider knowledge of systems and processes into a framework centred on the concept of ‘ecosystem functioning’.
The module is structured as three types of lectures, as well as a practical component. Lectures are on: (i) The main Drivers of Marine Ecosystem Function; these lectures aim to generate in students an understanding of the factors that underpin ecosystem functioning, as well as the factors that can cause ecosystems to change; (ii) Selected Marine Ecosystems (estuarine, mangrove, coastal shelf seas, pelagic, benthic and deep ocean); these lectures aim to illustrate ecosystem functioning, and aspects that affect ecosystem function, in an array of marine ecosystems; and (iii) Lectures on important current Global Impacts on the functioning of marine ecosystems: climate change, ocean acidification, invasive species, coastal development and fisheries disturbance. A practical component explores functional diversity in a coral reef setting, through analysis of published data. In three practicals the dataset is processed, analysed and presented (poster presentation).
The module takes as an over-arching theme the concepts of ecosystem functioning and ecosystem services. It commences with 5 introductory lectures that illustrate the factors that underpin ecosystem functioning, as well as factors that can cause ecosystems to change. The key corner-stones that underpin ecosystem processes are detailed. A particular focus is made on exploring the role of biodiversity in maintaining ecosystem functions and services. Drivers of ecosystem change and resistance to change are considered in the contexts of ecosystem resilience, system vulnerability and ecosystem regime-shifts. The role of biodiversity in maintaining resilience in marine systems is examined. Factors that determine secondary production of systems are considered, with particular focus on fisheries, marie vertebrates, zooplankton and marine benthos.
The practical shapes of ecosystem functioning, services, resilience and vulnerability are then illustrated by a series of lectures that consider the biology, ecology and conservational status of key ecosystems in detail. Systems for which particular focus is made are: estuaries, mangroves, coastal shelf seas, pelagic systems, deep sea benthos and deep sea mounts.
The module also has emphasis on reviewing the influences of some of the most important current drivers of change in marine ecosystems (‘Global Impacts’). Six dedicated lectures examine the effects of invasive species, ocean acidification, climate change, benthic exploration and fisheries disturbance on the functioning of marine ecosystems.
The course includes a marked course-work component. A three-session practical focuses on examining how guilds of coral reef fishes interact with coral reef structure. This component has particular emphasis on how functional diversity of coral reefs affect the traits of reef fishes. In the first practical session, students work in groups and are asked to process an existing dataset, using R Statistics. I the second session, students progress to analyse the data and present it graphically. Students then, individually, produce a poster for assessment, from where two continuous-assessment marks arise; one poster mark arises from presenting the poster in a poster conference; the other mark is allocated to the quality of the poster itself (content, structure, design, appearance).
Knowledge extending beyond the directly taught programme with evidence of enquiry beyond that contained in lectures, and beyond that derived from internet resources; excellent ability to integrate lines of evidence from a range of sources to support findings and hypotheses, excellent understanding of subject specific theories, concepts and principles, good ability to consider issues from a range of multi-disciplinary and inter-disciplinary perspectives. Consistent and frequent referencing to relevant literature.
Knowledge based on the directly taught programme, basic ability to integrate lines of evidence from a range of sources to support findings and hypotheses, basic understanding of subject specific theories, concepts and principles, basic ability to consider issues from a range of multi-disciplinary and inter-disciplinary perspectives.

Semester 2 exam
|COURSEWORK||Presentation of Scientific Poster||
Students present posters to their peers and markers. Marked during the poster presentation.
|COURSEWORK||Quality of Scientific Poster||
Students submit an electronic copy of their poster. This is marked using a marking Rubric.
Teaching and Learning Strategy
Directed reading based on the course content and reading lists given. The student may in addition use web-based references, videos and images.
Questionnaire design task and group presentation
|Practical classes and workshops||
Three practical sessions lasting a total of 13 contact hours. This is split into three practicals: (1) a 5 hour practical in which students, working in groups, develop a survey questionnaire. (2) A 5 hour practical in which students analyse their survey results and draft a group presentation. (3) A 3 hour practical in which student groups present the results of their student surveys. (4) A 3 hour practical in which students present their posters.
