The Biology of Mammals

Module description

The biology of mammals and our relationships with them are often what attracted us most to a degree and career in zoology, ecology or conservation. In this course, we first build a foundation understanding of mammalian evolution and classification. We then explore the form and function, evolution, adaptation, ecology and management of recent mammals. We will use case studies to illustrate specific processes, often focusing on the unusual and exceptional. In the lab and in online practicals we will explore anatomy and morphology using dissections of wild mammals, while online we will share experiences of people and practice in mammalogy in a series of “in-conversation” sessions.

Module aims - intentions of the module

This module will build on the Stage 1 Introduction to Vertebrate Zoology and lay a foundation for Stage 3 modules and field courses. Because the content spans evolution, behaviour and conservation this module will knit well with other Stage 2 modules and will suit all degree pathways. The aim is to establish a firm knowledge of the evolution and classification of mammals and then to explore mammalian diversity in form and function, across a breadth of taxa and environments. Case studies will be used to illustrate the insights that mammals provide into evolution and ecology in a wider context and will include reproduction, feeding, life history variation, domestication, diseases, conservation and management.

This module will provide a grounding in topics relevant to employment in research, policy and environmental management and regulation. The module builds on basic aspects of biology, then develops these, extending through to understanding of complex management and conservation scenarios. By completing the assessments you will develop the following skills that will transfer to future challenges in the workplace:

• Independently formulating ideas and testing/evaluating these
• Identifying, selecting and using information from disparate, and sometimes conflicting, sources
• Prioritising information for presentation with constraints on time, space and style
• Clear and succinct technical communication

Teaching on this module draws on research undertaken by Robbie McDonald on mammalian ecology, diseases, management and conservation, particularly of British mammals, and by Andy Young in relation to mammalian reproduction, mating systems and sociality.

Intended Learning Outcomes (ILOs)

ILO: Module-specific skills

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

• 1. Describe the evolution and classification of mammals
• 2. Explain in detail a range of case studies of mammalian form and function, ecology and management
• 3. Exhibit confidence in safely handling, identifying and learning from mammalian specimens (live and dead)
• 4. Explain the role and importance of evolution and adaptation to contemporary biological challenges

ILO: Discipline-specific skills

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

• 5. Describe in some detail essential facts and theory across a sub-discipline of biosciences
• 6. Identify critical questions from the literature and synthesise research-informed examples from the literature into written work
• 7. Identify and implement, with guidance, appropriate methodologies and theories for addressing specific research problems in biosciences
• 8. With some guidance, deploy established techniques of analysis, practical investigation, and enquiry within biosciences
• 9. 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...

• 10. Develop, with some guidance, a logical and reasoned argument with valid conclusions
• 11. Communicate ideas, principles and theories fluently using a variety of formats in a manner appropriate to the intended audience
• 12. Collect and interpret appropriate data and complete research-like tasks, drawing on a range of sources, with limited guidance
• 13. Evaluate own strengths and weaknesses in relation to professional and practical skills, and apply own evaluation criteria
• 14. Reflect effectively on learning experiences and summarise personal achievements

Syllabus plan

Lectures will cover the basics of evolution and classification of mammals, then recap in more detail over major aspects of form and function in each of the taxonomic groupings. In each case we will identify and discuss in more detail major topics of ecology, behaviour and management, including

• evolution and classification
• homeostasis, feeding, locomotion
• reproduction, mating systems, life history and communications
• domestication
• diseases
• conservation
• biological invasions

Practicals will cover the form and function of mammals. In the laboratory we will dissect samples collected from pest control operations and, where possible, we will participate online in a necropsy investigation of marine mammal strandings. Online, we will participate in a series of ‘in-conversation’ discussions on people and practice in mammalogy.

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 assessment. 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%.
