Chapter 51 Guided Reading
1. How do behavioral ecologists define behavior?
Behavioral ecologists define behavior as everything an animal does and how it does it
2. What is the focus of:
a. Proximate questions of behavior?
Focuses on the environmental stimuli, if any, that trigger a particular behavioral act, as well as the genetic, physiological, and anatomical mechanisms underlying it.
b. Ultimate questions of behavior?
Focuses on the evolutionary significance of a behavioral act.
3. Define the following terms:
a. Ethology- the study of animal behavior in natural conditions
b. Fixed action pattern- (FAP) a sequence of unlearned behavioral acts that is essentially unchangeable and usually carried …show more content…
Look up the definition of natural selection or review briefly the first chapter pages 15 – 18. Using this framework proved two different examples of the relationship between behavioral trait and natural selection. Why does this relationship “make sense”?
A trait of fish is to swim in schools because they have a smaller chance of being eaten since they look bigger. Most Wolves hunt in packs because it is much more efficient and you have others to back you up.
13. The statement can be made that “there are risks and benefits” to everything.” How does this relate to the optimal foraging theory?
The theory states that natural selection will favor animals that have developed foraging methods that use less energy and are at less of a risk of being killed while obtaining the food. This theory wants the risk of being killed to be small as possible and the benefits to be as large as possible.
14. What is generally the most important factor in the evolution of mating systems and why does this “make sense’?
The most important factor in the evolution of mating systems is the survival of offspring. This “makes sense” because the mating systems that worked (produced offspring), are going to be repeated in the succeeding generation. If a mating system is unproductive, their will be no offspring to continue doing
