Exam 7: Territoriality and Movement

Even when an intruder is far away, territorial male Broadley's flat lizards will charge them aggressively. However, when a familiar neighbor approaches, territorial males allow these individuals to get much closer. They will also pursue them for a much shorter span than an unfamiliar intruder. This finding illustrates the

Refer to the figure. The graph represents

The finding that both great white pelicans and brown pelicans fly in V-formation is an example of

Refer to the figure. Based on the ideal free distribution theory, you may predict that

Refer to the figure. "The birds in front of the V are expected to be low-ranking birds that are unable to displace physically superior rivals from the more energy-saving positions in the formation." This statement is a

If the distribution of individuals over a set of habitats is consistent with ideal free distribution theory, then

Refer to the figure. Based on resource-holding potential, redstarts with the best competitive ability should be found in the

A bird defends a territory in which there are abundant food sources but also high levels of predation. This is an example of

Refer to the figure. Does this result support ideal free distribution? Why or why not?

Refer to the figure. This work would be based on optimality theory if the

The inbreeding avoidance hypothesis is used to explain

Describe two environmental cues that animals use to navigate during migration.

Male American redstarts (a small species of warbler) that are in the best physical condition typically are found in the species' preferred habitat. Individuals in worse condition tend to be found in scrubby, secondary growth. This statement supports the

While studying a species of firefly, you notice that the territories they occupy are constant across the breeding season, even though you observe multiple, short territorial disputes. Despite these quick disputes, you do not observe a single case of a territory actually changing ownership. This finding supports the

Explain the similarities and differences between dispersal and migration.

If two cats are introduced into a new home, the one that is brought in a day or two before the other will more strongly defend the space as its territory. This illustrates the

Refer to the figure. The figure shows flight energetics in great white pelicans that are gliding by themselves, flapping by themselves, or traveling in a group V-formation (indicated by the numbered individuals). What is the mean wingbeat frequency (in wingbeats per minute) of a pelican leading the V-formation?

Refer to the figure. Based on these results, which habitat is most preferred by the shorebirds?

Passive dispersal is most likely to be used by which type of species?

How does understanding migratory behavior and connectivity between a species' breeding and wintering grounds help improve conservation efforts? Use an example to support your answer.
