Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.

California to give birth. How might such behavior make it easier
for ecologists to estimate birth and death rates for the species?

A species is considered to be endangered if it is expected to be extinct within 20years. A population of porpoise has approximately 1, 150 members alive today, and thepopulation has been steadily declining at an annual rate of about 36% over the pastdecade. In what year is the population expected to have only 1 individual left alive?Should this species of porpoise be considered endangered?
Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.

The Atlantic cod population is of primary economic importance to fishingcommunities throughout the maritime provinces in Canada. Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.
