Behaviour as a Biological Adaptation
Flashcards do conjunto (11)
- 1State why it is important to acknowledge behaviour1). To identify housing and husbandry practices likely to lead to health and welfare problems
2). To spot abnormal or problematic behaviour that indicates health and welfare problems
3). To give first opinion on companion animal behaviour problems - 2What is the First of Tinbergen's Four Questions?Mechanism- Causation:
How is behaviour caused? What are underlying physiological mechanism? Genetic basis? Motivational control? Hormones? - 3What is the Second and Third of Tinbergen's Four Questions?Function- Survival value: What is the behaviour for? What is its fitness advantage? Why has it evolved?
Evolution: Where has the behaviour come from? How has it evolved? - 4What is Tinbergen's Fourth Question?Development- Ontogeny: How does the behaviour develop during the lifetime of an individual?
- 5How are these question split into Two Groups?Proximate: Development and Mechanism
Ultimate: Function and Evolutionary History - 6Define "Adaptations"Changes in animal brought about during evolution by process of natural selection
- 7How are Behaviours a Phenotypic trait?- Behaviour have variations
- Behaviour can have positive or negative influences on survival value and fitness - 8What influences behaviour action?Environment and genes directly impact behaviour action which go on to effect immediate outcome ---> fitness which then leads to genes
- 9How has domestication altered this process?Artificial selection has replaced natural selection, leading to a selection of desirable production, behaviour and aesthetic traits.
When behaviour has NOT been selected for, it has the biggest welfare implications. - 10How can health and welfare implications of a behaviour be assessed?Approach 1: How not-natural is the behaviour of captive or domestic animals?
Approach 2: How adaptive is the behaviour of captive or domestic animals in current conditions? (via welfare assessment) - 11What are two methods of deciding how "not-natural" a behaviour is?A: Compare behaviour repertoire of captive, domestic species with ancestral species'
B: Examine behaviour of captive, domestic animals released into 'wild' environment
