20 Credits or 10 ECTS Credits

Semester 1

Organiser: Dr Gareth Williams

Overall aims and purpose

This module is designed to introduce students to the ways in which various biological and physical environmental factors and their interactions can control community organisation and population structure in a selection of benthic systems ranging from the inter-tidal zone to coastal shelf seas. Examples will be taken from both temperate and tropical regions and will include coral reefs, kelp forests, rocky shores, soft sediment ecosystems, mangroves, and seagrass meadows. Students will undertake fieldwork on a rocky shore in the Menai Strait. Students will also undertake a computer-based practical where they will analyse existing data from a coral reef ecosystem to examine for environmental correlates of community structure across zonation gradients.

Course content

Topics covered will include: rocky shore ecology, keystone species, physical and biological factors, zonation, disturbance, succession, macro-algal production. Soft sediment ecology, saltmarsh, seagrasses, mangroves, tropical and temperate soft sediment shores. Sub-tidal hard substrate ecology, temperate reefs, physical and biological factors, community structure, exposure. Coral reef ecology, types and formation, algal symbiosis, biodiversity and productivity, community structure, development and change, processes leading to stable communities, native (and invasive) species, community resilience and disease as a form of disturbance.

Assessment Criteria

threshold

Basic knowledge derived from the lectures and some prescribed reading, but with limited ability to critically synthesize this basic knowledge

good

Knowledge based around lectures and, for marks at the higher end of the scale, with clear evidence of reading the prescribed literature outside the lectures. The student understands the fundamentals and demonstrates some ability to critically synthesize the various strands of information.

excellent

Clear and concise presentation of the fundamentals and the details of all areas of the module supported by reading prescribed (and other) literature outside the lectures. Highly developed ability to critically synthesize the module information and to link with other modules in the programme.

Learning outcomes

  1. Gain experience of rocky shore sampling techniques through field work on an Anglesey rocky shore

  2. Comprehend the physical and biological factors controlling local geographical distribution patterns of temperate and tropical marine organisms.

  3. Understand concepts of marine community structure and biodiversity

  4. Identify and comment on a range of common intertidal organisms that were encountered during the field work practical

  5. Gain experience in processing biological data from a coral reef ecosystem to identify biological community spatial patterns

Private study

Directed Study of material in the form of illustrations, references to journal articles, reviews and book chapters will be placed on Blackboard for the students to access. Students will be directed to particular material during the course of the module. There is an expectation that elements of the directed reading will be used to support the lecture material when students are answering essay questions in the final examination.
