Ch. 6 Reading Study Guide Animal behavior and wildlife management This chapter is about the broad field of ethology or animal behavior and some of the key things have learned and how they relate to wildlife management. The chapter also covers animal migration ad its special effects on wildlife management. 1. Habitat selection 1. the ability to recognize suitable habitat seems to be innate (instinctive). 1. this makes good evolutionary sense. Selective pressure would be very high against animals that could not select habitats that they could survive in. 2. examples of several studies are presented that showed animals instinctive ability to pick the right habitat 2. some animals can modify this primarily instinctive behavior based upon early learning 1. If I grew up successfully in habitat A, I might have learned ways to use habitat A, even though instinctively my species uses habitat B. 2. knowledge of the local area increases my chances for survival 3. Understanding wildlife behavior is Important for management because 1. we cannot judge habitat solely on human standards 2. what appears good to us may not, in fact, provide the necessary stimuli (cues) to trigger an animals instinctive recognition of the habitat as adequate 3. successional changes in habitats will reduce habitat quality for some species, even though it may be improving it for others. 4. if left unmanaged, many kinds of habitats will no longer suit the innate, unchangeable, preferences of wildlife species 5. It is easier to change the habitat than it is to change the behavior of the species. 2. Courtship behavior 1. breeding behaviors are frequently a key to wildlife management 1. they are often stereotypic and obvious activities of wildlife that make it easier for humans to detect them. 2. they occur at regular times of the year and, 3. they can serve as good indices to how many animals are in the population. 2. the text also presents an example (black ducks and mallards) where changing habitats, modified by humans, has created a hybridization problem between closely related species because they had not evolved distinct behavioral cues for mate selection. 3. Reproductive physiology and behavior 1. most animals, unlike humans, are not capable of breeding year-round. They undergo physiological changes that gear up their reproductive systems for breeding

1. these physiological changes are often keyed to changes in the environment that indicate the season for successful breeding is near. 1.
