BIO 3176 Lecture Notes - Lecture 19: Signalling Theory, Begging
Document Summary
Purpose of behaviour is to protect defenseless individuals. Costs = energy, time, high risk of engaging aggressive predators. Away from colony, only costs no benefits --> no mobbing. Recognizing when increasing conspicuousness and making yourself tired --> risky. Let the predator know which to chase and not. Needs to be difficult to do --> honest signal. Choose the right background, substrate etc. , choose what to do, orientation, movements. Describe and discuss data --> from that show how it relates. Bar graph tells us that sounds out of a speaker nest. When any call --> increase predation compared to control. Adaptation to decrease predation, decrease cost of begging. Begging --> costs and benefits, benefits of eating, costs, alerting predators. On ground --> greater chance of being discovered (like more predators) Lower frequencies travel farther in dense forest compared to high frequencies. Same as short answer question 1, but describe data.
