Document Summary
Three ways to learning about behavioural ecology: eating or being eaten (cid:224) animals make behavioural choices that enhance their energy gain and reduce their risk of becoming prey, reproduction (cid:224) mating behaviour reflect the costs and benefits of parental investment and mate defense, living in groups and how we behave within them (cid:224) there are advantages and disadvantages to living in groups. Adaptive animal behaviour: proximate causes (immediate): how the behaviour occurs, ultimate causes: why the behaviour occurs the evolutionary and historical, behavioral ecologists mostly focus on ultimate causes, many studies have documented adaptive behavioural change reasons. P= e t rate for the: an animal"s success in acquiring food increases with the effort it invests (cid:224) at some point, more effort results in no more benefit, and the net energy obtained begins to decrease, study: proportions of prey types and encounter rates were varied in great tits.
