Description

Aims:

  • to provide a thorough grounding in the adaptive, or functional, approach to the study of animal behaviour.
  • to provide an understanding of the different ways to test scientific hypotheses about animal behaviour and the limitations of different approaches.
  • to provide a secure grounding for practical projects relating to animal behaviour.

Behavioural Ecology is all about why do animals do what they do, and how behaviour is adapted to ecological circumstances. This unit emphasises functional and evolutionary explanations of behaviour, rather than the investigation of mechanisms and development of behaviour covered in BIOL 20103 Acquisition of Behaviour. A complete understanding of behaviour involves both approaches, so we view this unit as complementary to BIOL 20103. Topics include: Foraging and resource acquisition, optimality theory, trade-offs and the organisation of behaviour, evolutionary games, sexual selection, mating systems, parental care, communication, territoriality and social organisation, co-operation and altruism. The practical part of the unit does not merely serve to illustrate material in the lectures, it covers additional topics best explained by hands-on experience.

Intended learning outcomes

After doing the Unit, we expect you to (1) appreciate the distinction between the different levels of analysing behaviour ("Tinbergen's four questions"), (2) be able to explain the basic principles behind the main theoretical models in behavioural ecology, namely optimality theory, game theory, sexual selection and kin selection, (3) be able to relate these models to the various types of behaviour they have been used to explain (N.B. the same models are applied to more than one lecture topic), (4) be able to devise simple ways of generating and testing hypotheses about the function of animal behaviour, and the limitations of different approaches.

Teaching details

Lectures, directed reading, research and/or problem-solving activities; practical exercises and independent study.

Assessment Details

Coursework (40%) plus summative written assessment (60%) with one essay question to be selected from a choice of two.
