Behavioral Ecology Behavioral ecology emphasizes evolutionary hypotheses: Behavioral ecology is the research field that views behavior as an evolutionary adaptation to the natural ecological conditions of animals. We expect animals to behave in ways that maximize their fitness (this idea is valid only if genes influence behavior). http://biosci.usc.edu/courses/2002-fall/documents/bisc121-fuhrman_ch51.ppt

Proximate vs. Ultimate Behavior has both proximate and ultimate causes: Proximate questions are mechanistic, concerned with the environmental stimuli that trigger a behavior, as well as the genetic and physiological mechanisms underlying a behavioral act. Ultimate questions address the evolutionary significance for a behavior and why natural selection favors this behavior. http://biosci.usc.edu/courses/2002-fall/documents/bisc121-fuhrman_ch51.ppt

Imprinting Imprinting is the recognition, response, and attachment of young to a particular adult or object. Konrad Lorenz experimented with geese that spent the first hours of their life with him and after time responded to him as their “parent.” Lorenz isolated geese after hatching and found that they could no longer imprint on anything. http://biosci.usc.edu/courses/2002-fall/documents/bisc121-fuhrman_ch51.ppt

Imprinting Stimulus What is innate in these birds is the ability to respond to a parent figure; while the outside world provides the imprinting stimulus . ht p:/ biosci.usc.edu/courses/2002-fal /documents/bisc121-fuhrman_ch51.ppt The Sensitive Period is a limited phase in an individual animal’s development when learning particular behaviors can take place . ht p:/ biosci.usc.edu/courses/2002-fal /documents/bisc121-fuhrman_ch51.ppt
