SCIENTIFIC INQUIRY Scientists studying scrub jays found that “helpers” often assist mated pairs of birds by gathering food for their offspring.
(A) Propose a hypothesis to explain what advantage there might be for the helpers to engage in this behavior instead of seeking their own territories and mates.
(B) Explain how you would test your hypothesis. If it is correct, what results would you expect your tests to yield?

1) how can you use the data to better understand how the penguins capture prey? You may wish to find the average time it takes the penguin to capture each of the types of prey. You could organize the data into a table. 2) after data, analyze the data as described in question one
Female parasitoid wasps search for insect hosts in which to lay eggs, and they can often discriminate among individual hosts that are more or less suitable for their offspring. Behavioral ecologists have asked whether or not the wasps’ willingness to lay eggs in less suitable hosts varies with the female’s age. On the basis of life history theory, what pattern of change would you predict? Does life history theory make any other predictions about animal behavior?

- INTERPRET DATA Look at the two graphs in Figure 52-21. In which experiment did the parentals in the experimental group guard the eggs more closely? In which experiment did the experimental parentals guard the young more closely? Account for these differences. RESULTS: Experiment 1: As indicated on the y-axis, which measures level of parental care, parentals reduced their level of guarding the eggs. Eight of the males in the experimental group abandoned their nests, and egg defense was significantly lower in this group compared with that in the control group. However, after eggs hatched, there was little difference in parental care of the young between the two groups. Experiment 2: During the egg phase, there was little difference in level of parental care between experimental and control groups. However, after eggs hatched, the experimental parentals significantly decreased their level of guarding the nest. CONCLUSION: Male bluegill sunfish adjust their level of parental care according to their level of perceived paternity. In Experiment 1, parentals provided less care when they perceived that the eggs may have been fertilized by sneaker males. After the eggs hatched, olfactory cues indicated that the offspring were indeed their own, and their level of care increased. In Experiment 2, parentals cared for the eggs even though some had been swapped. However, after they hatched, olfactory cues from the offspring indicated that they were not the parentals own offspring. The level of parental care decreased significantly. SOURCE: B.D.

A number of dinosaur lineages had feathered dinosaurs, not just the lineage that includes living birds. Do you think that is it justified to believe that all feathered dinosaurs had behaviors known from living birds? Such behaviors of birds include colonial nesting, sexual displays by males using feathers, males moving to display their ornamental feathers to female mates.

Do you think money should be spent for captive breeding programs ? why or why not?arrow_forward1) Think back to the example of ovenbird evoluon in South America. Ovenbirds are a diverse family of small, insect-eang birds that live mainly in South America. Different ovenbird species have adapted to rocky ocean shorelines, snowy mountains, scorched deserts and tropical rainforests. Like finches, ovenbirds have a variety of beak sizes and shapes, an important indicator of food preference that makes them ideal for studying evoluon. In ovenbirds, "some [beaks] are long and down-curved, like a scythe, for probing into crevices in tree bark and others have short dagger-like bills." What conclusions did the researchers reach? A) ovenbirds are diverse because they do not share any common ancestors B) ovenbirds because successful because they are not native to the area and could easily colonize the area C) birds have different beaks that help them exploit different resources and avoid competition 2) One ant species from Africa is best at competing for space, but is worse at colonizing a…arrow_forwardSCIENCE, TECHNOLOGY, AND SOCIETY Consider how the adaptive value of sea turtle migration has changed if, as a result of human activities, migration now puts sea turtles at greater risk than if they restricted their habitat to a single location.

What conservation efforts should we take to increase the probability of successful migration?arrow_forward
