Behavioral Ecology Heyer 1 Behavior Behavior : change in activity in response to stimuli : change in activity in response to stimuli – Is what an animal does and how it does it Is what an animal does and how it does it – Includes muscular and non-muscular activity Includes muscular and non-muscular activity Cognition Cognition : the ability of an animal : the ability of an animal ’s nervous system to s nervous system to perceive, store, process, and use information gathered by perceive, store, process, and use information gathered by sensory receptors sensory receptors Signal Signal : a behavior that causes a change in another animal ’s behavior behavior – Visual, auditory, chemical, [pheromones] electromagnetic Visual, auditory, chemical, [pheromones] electromagnetic Communication Communication : the reception of and response to signals : the reception of and response to signals Learning Learning : the modification of behavior based on specific experiences experiences What Is Behavior? Behavioral Biology: Ethology • Studying behavior in the natural setting. Alan Rabinowitz radio-tagging jaguars for behavioral study in Belize. Behavioral Biology: Experimental • Isolating and manipulating specific behaviors. Using artificial star patterns to study stellar navigation in indigo buntings Behavioral Ecology • Evaluating how behavior relates to niche. Optimal foraging strategies: Natural selection favors feeding behavior that maximizes energy gain and minimizes the expenditure of time and energy. Tapirs have 40x more meat, but are much harder to find and catch. So jaguars prefer armadillos. Nature vs. Nurture Analyzing the roles of inherited characteristics ( innate behaviors ) and environmental conditioning ( learned behaviors ) on the overall behavior of a particular organism. Innate behaviors: no need to risk failures; correct from the first time. Learned behaviors: more dynamic, complex, and able to adapt to various situations. ß Capacity for learning best developed in animals with complex nervous systems (sensory and memory), long life-spans, and parental care.
