Description - summary of the module content

Module description

Marine megavertebrates (including turtles, sharks, rays, cetaceans, penguins and other aquatic birds) are generally considered very charismatic animals and attract much public and research attention. As a group they also adapt to the challenges of life in water in a diverse range of ways. Building on Stage 1 and 2 modules, you will learn about the different form, function, ecology and physiology of each group of megavertebrates. You will also use practical work to learn some of the core techniques in modern marine vertebrate research in more detail, and research-led teaching to understand the very latest developments in the field. The module will also provide you with key employability skills in analysis and communication.

Module aims - intentions of the module

The aim of the module is to provide you with an in-depth insight into the range of adaptations for life in the water and the ways in which biology has adapted to cope with the challenges of low oxygen, high pressure and unpredictability in resources. This insight will help you to develop your critical and creative thinking about how life has adapted to deal with specific challenges, and provide key employability skills in analysis and communication. The practical knowledge and skills acquired by taking this module are relevant to many areas of employment such as conservation, consultancy, environmental planning, medicine and forensics. By taking part in the practicals you will learn skills of observation, accurate data recording and demonstrate critical thinking which are key to careers in fundamental and applied sciences. The module content is updated every year to explore topical research areas, some of which are being carried out in the department, and some of which are of global relevance. For example, we debate cutting edge research into animal biologging and conservation. You will learn about the tools required to study such problems, and explore how such science can inform policy and practice which is useful in the context of careers in conservation policy, science, in NGO and consultancy as well as academia.

Intended Learning Outcomes (ILOs)

ILO: Module-specific skills

On successfully completing the module you will be able to...

  • 1. Describe the form, function, basic ecology and physiology and role and importance of a range of marine megavertebrates
  • 2. Critically evaluate a range of case studies concerning marine vertebrate form, function, ecology and physiology

ILO: Discipline-specific skills

On successfully completing the module you will be able to...

  • 3. Identify critical questions and methodologies from the literature and synthesise research-informed examples from the literature into written work
  • 4. With limited guidance, deploy established techniques of analysis, practical investigation, and enquiry within biosciences
  • 5. Describe and evaluate approaches to our understanding of biosciences with reference to primary literature, reviews and research articles

ILO: Personal and key skills

On successfully completing the module you will be able to...

  • 6. Communicate ideas, principles and theories fluently using a variety of formats in a manner appropriate to the intended audience
  • 7. Collect and interpret appropriate data and complete research-like tasks, drawing on a range of sources, with limited guidance

Syllabus plan

Syllabus plan

Lectures will cover the form, function, ecology and physiology of a range of aquatic vertebrate groups, with specific case studies looking into species that have been well studied. For example, diving physiology of elephant seals and emperor penguins, thermal ranges of aquatic vertebrates, foraging energetics of large fish and sharks.

Lectures will include, but are not limited to:

  • Introduction to the module, structure and assessment and key learning outcomes
  • Major marine vertebrate groups
  • The physiology of diving
  • Biologging – the use of electronic attached tags to record behaviour and movement of marine vertebrates
  • The impact of underwater sound on marine vertebrates
  • The exploitation and conservation of marine vertebrates

Practicals will teach the use of spatial ecology, mapping and data plotting to analyse electronic biologging data in horizontal (movement) and vertical (diving) planes using open source software.

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. The mark given for a re-assessment taken as a result of referral will count for 100% of the final mark and will be capped at 40%.
