Exam 35: Behavioral Adaptations to the Environment

An insectivorous bird has the choice of eating (1)meadow beetles, which are abundant and large but expose the bird to hawk predation, (2)under-a-rock beetles, which are large and fatty but hard to obtain, or (3)under-a-leaf beetles, which are easy to obtain but small. The bird has nestlings to feed. As an optimal forager, it will

Organisms that are nocturnal are more likely to communicate using

Which of the following is an example of a fixed action pattern?

Endocrine disruptors on reproductive behavior affect behavior by

Which of the following is communicated by courtship displays?

What type of behavior is illustrated by the bird in this figure?

Which of the following statements is false?

After reading the paragraph below, answer the questions that follow. In examining the effects of atrazine, one of the most commonly used herbicides in the world, scientists studied the mating behavior of male frogs exposed to atrazine (Atr) compared to a group that was not exposed (Non). The results are shown in the figure. -The experiment in part C adds to the conclusions by

After reading the paragraph below, answer the questions that follow. In examining the effects of atrazine, one of the most commonly used herbicides in the world, scientists studied the mating behavior of male frogs exposed to atrazine (Atr) compared to a group that was not exposed (Non). The results are shown in the figure. -The experiment in part A was important to the overall conclusions by demonstrating all of the following except

The need for intense parental care of offspring favors mating systems that are

In a study on human mate choice, researchers found that daughters choose mates who look like their fathers. To determine whether they choose mates who are genetically similar, the mate choices of adopted daughters were analyzed. Independent judges determined that adopted daughters chose mates with facial similarities to their adoptive father. This influence of parental image on mate choice could be considered a human example of

After reading the paragraphs below, answer the questions that follow. A researcher is investigating the ability of salmon to migrate thousands of miles in the ocean yet return to the location where they were hatched to spawn. Data from experiments suggest that more than one type of homing mechanism may be involved in this behavior. When salmon arrive at a river mouth from the open sea, they appear to use olfactory cues to find their home streams, but how do they find their way back to the correct spot along the coastline from the open ocean? Several experiments were carried out to test the hypothesis that geomagnetic factors (the influence of Earth's magnetic field) play a key role in the ability of salmon to find the proper location along the coast. In one such experiment, salmon hatched in Ketchikan, Alaska were subjected to the geomagnetic characteristics of a different location on the Alaska Peninsula, Cold Bay. The fish were then released to determine to which of the two locations they would return to spawn. -What type of behavior would explain the ability of the salmon to return to their home streams?

A grayling butterfly will normally fly toward the sun. This is an example of

Which of the following statements about chimpanzee behavior is true?

A male turkey that imprinted onto a human at hatching is transferred as an older juvenile to a flock of "normal" turkeys. When this turkey reaches sexual maturity, he will probably try to court

Which of the following situations could represent kin selection in action?

Several primates have been taught to communicate with humans using sign language. This supports the view that animals other than humans can learn through the process of

Squirrels seem to be able to figure out how to steal seeds from bird feeders no matter what people do to try to stop them. One day, Jeremy put out a bird feeder with a new design, and sure enough, by the end of the day the squirrels were snacking on the seeds. The squirrels most likely figured out how to get the seeds through

Territories are typically used for activities such as

Baby bobcats watched as their mother stalked a rabbit and pounced, catching a meal that was shared by all. The next day, two of the young bobcats were seen stalking a field mouse, which easily escaped from the inexperienced hunters. The young bobcats were learning how to hunt by the process of
