Document Summary
Behavioural ecology: investigates the ecological and evolutionary basis of the behaviour of organisms in response to particular stimuli from their environments. Key concept: individuals that behave altruistically are usually helping relatives or individuals that help them in return key concept: most behavioural studies start by observing animals, then they use experimental approaches to probe proximate and ultimate causes of behaviour. Proximate/mechanistic causation: explains how actions occur: neurological hormonal skeletal-muscular mechanism. Innate, inflexible behaviour is rare: fixed action patterns: highly inflexible stereotyped behaviour patterns ex. kangaroo jumping back from the sound of a rattle snake innate behaviours: inherited, little variation based on learning. Most behaviour is flexible and condition dependent: More common for animals to : change in response to learning, show flexibility in response to changing environmental conditions. Male actively solicits his own consumption females won"t eat males that do not go purposely onto their jaws. 8. 2: question 1: what should i eat? foraging = seeking food.
