Questions and Answers
What is Behavioral Ecology?
Behavioral ecology is concerned with functional questions about behaviour, namely how a particular behavioural pattern contributes to an animal’s chances of survival and reproductive success.
What does natural selection refer to?
What are adaptations in the context of behavioral ecology?
Adaptations are evolutionary changes that provide a selective advantage.
Behaviours that provide a _____ advantage are favored by natural selection.

Study Notes
Introduction to Behavioural Ecology
- Focuses on the interactions between behaviour, ecology, and evolution, exploring how and why specific behaviours evolve.
- Central questions: Why has a specific behaviour evolved? What are the adaptive advantages of behaviours like group living or mating strategies?
Natural Selection
- A process by which species adapt to their environments through evolutionary changes.
- Behaviour adapted to an environment provides a selective advantage, known as adaptive significance.
Purpose of Behavioural Ecology
- Aims to determine how animal behaviour influences survival and reproductive success within their environment.
- Investigates functional questions related to adaptations of behaviour to changing environments.
Founders of Behavioural Ecology
- Konrad Lorenz: Studied innate behaviours and instinct. Introduced concepts like imprinting, highlighting genetically determined behaviours.
- Niko Tinbergen: Focused on instincts and learned behaviours for survival. Developed research methods including controlled experiments and observational studies.
Key Concepts in Behaviour
- Imprinting: A process whereby certain animals develop attachments during a critical period post-hatching, promoting survival.
- Ethology: The study of animal behaviour in natural conditions, viewing behaviours as evolutionarily adaptive traits.
Tinbergen's Four Questions
- Causation: What physiological mechanisms control behaviour?
- Ontogeny: How does behaviour develop throughout an individual's life?
- Adaptive Value: What function does the behaviour serve in terms of survival?
- Phylogeny: What evolutionary changes have led to current behaviours?
Proximate vs Ultimate Causes
- Proximate Causes: Mechanisms that explain how behaviours are executed (e.g., hormones, environmental triggers).
- Ultimate Causes: Evolutionary reasons behind behaviours (e.g., natural selection, reproductive strategies).
Examples Illustrating Proximate and Ultimate Causes
-
Migration:
- Proximate: Triggered by changes in light and temperature.
- Ultimate: Adapted through evolution to avoid starvation.
-
Peacock Display:
- Proximate: Driven by hormone levels and genetic factors.
- Ultimate: Linked to sexual selection for attracting mates.
Practical Applications
- Distinguishing between causal (proximate) and functional (ultimate) explanations of animal behaviour is essential for experiments and research in behavioural ecology.
