Document Summary
Concept 8. 3 mating behaviors reflect the costs and benefits of parental investment and mate defense. Concept 8. 4 there are advantages and disadvantages to living in groups. Animal"s behavioural decisions play a critical role in activities such as obtaining food, finding mates, avoiding predators. Have costs and benefits that affect individuals ability to survive and reproduce. Behavioral ecology is the study of the ecological and evolutionary basis of animal behaviour. Concept 8. 1 an evolutionary approach to the study of behavior leads to testable predictions. Robins tilt head to hear for worms in ground, 2 explanations: Focus on how the required sensory equipment works. Focus on whether listening for worms increases efficiency of foraging, thus enhancing birds survival and reproductive success. Proximate causes: focusing on events that take place during an animals lifetime, this approach seeks to explain behaviours. Ultimate causes: addressing previous events that influenced the features of an animal as we know today.
