Exam 13: Social Behavior and Sociality

Refer to the figure. Due to conservation efforts, this population of Seychelles warblers increased from 1959 to 1990. How does the relationship between the number of birds and number of territories change over this period?

Behavioral syndromes are

The fungus Ophiocordyceps manipulates the behavior of worker ants by infecting them with fungal spores, causing them to descend to the understory where conditions for fungal development are optimal, but the ants die. This is an example of

Refer to the figure. The point of the prisoner's dilemma diagram is to

The prisoner's dilemma describes

Refer to the figure. The female white-fronted bee-eater has several options to choose among when deciding to reproduce. What factors affect whether the female stays in her natal territory?

Refer to the figure. Horizontal bars represent the maximum life spans of three successive generations in each species. The blue shaded areas are the mean reproductive spans. What hypothesis do these results support?

Refer to the figure. Due to conservation efforts, this population of Seychelles warblers increased from 1959 to 1990. Following the ecological constraints hypothesis, in what year would you predict that helping behavior began to occur in this population?

Refer to the figure. Primary helpers are less likely to survive and reproduce the following year than secondary helpers. Based on the results shown here, we can predict that primary helpers are

Refer to the figure. Based on these results from a study on 267 species of birds, we can conclude that

Why do lions hunt together? In your answer, indicate the fitness payoffs for individuals of the group conferred by the behavior of (nonreciprocal) altruism.

Describe the relationship between the grandmother hypothesis and reproductive senescence, and provide an example of a species that illustrates this hypothesis.

Why do lions hunt together? In your answer, indicate the fitness payoffs for individuals of the group conferred by the behavior of reciprocity.

In reciprocity, we hypothesize that an individual engages in a selfless act because they will be "repaid" by the recipient in the future. This expectation is likely to occur in all of the following scenarios, except:

Why do lions hunt together? In your answer, indicate the fitness payoffs for individuals of the group conferred by the behavior of selfishness.

Honeyguides (a small African bird) lead humans to bees' nests so the humans will make the wax honeycomb available to them. Similarly, cleaner fish remove ectoparasites from other reef fish. These are examples of

Why do lions hunt together? In your answer, indicate the fitness payoffs for individuals of the group conferred by the behavior of mutual benefit.

Kin selection theory is most useful in helping explain

Refer to the figure. Primary helpers are less likely to survive and reproduce the following year than secondary helpers. Based on the results shown here, we can predict that secondary helpers are

Refer to the figure. Horizontal bars represent the maximum life spans of three successive generations in each species. The blue shaded areas are the mean reproductive spans. These results indicate that compared to other primates, humans
