Textbook Question
Chapter 52, Problem 18TYU
SCIENCE, 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. Discuss the possible evolutionary mechanisms by which the behavior of these species may (or may not) adapt to these environmental pressures. What conservation efforts should we take to increase the probability of successful migration?

Conservation biologists have altered the evolution of salmon populations in captive-breeding programs. Wild female salmon tend to produce fewer large eggs because the large eggs contain more nutrients for the off spring, giving each individual a greater chance to survive. After just a few generations, however, captive-bred females now lay greater numbers of small eggs. Suggest a possible adaptive advantage for many small eggs in the captive-bred environment. What would you predict regarding the reproductive success of captive-bred females released in the wild?
Many lines of evidence, including biochemical evidence, show that living birds are direct descendants of dinosaurs. 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. Give a brief reason for your answer.
How can the migration patterns of the sea turtles be impacted? (Please explain this in 5-7 sentences.)

- One of Darwin’s finches, the medium ground finch (Geospiza fortis), is found on the small island of Daphne Major. These finches are seedeating birds. A major drought occurred on the island in 1977. Following the drought, the average beak size of medium ground finches had increased about 3%–4%. Why might a drought lead to an evolutionary change in beak size? Propose a hypothesis and explain how you could go about testing it.arrow_forwardFlightless birds on island often have relative on the mainland that can fly. The island species presumably evolved from fliers that, in the absences of predators, lost their ability to fly. Many island population of flightless birds are in decline because rats have been introduced to their previously isolated island habits. Despite current selection pressure in favor of flight, no flightless island bird species has regained the ability to fly. Why is this unlikely to happen?arrow_forwardAnswer the following: This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why do you suppose: (a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? Explain in detail. (b) This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it? Explain in detail.arrow_forward

- The Pipidae are a family of tongueless frogs that have one or more claws on their toes. While observing these frogs, you notice that males with more claws had more opportunities to mate and father more offspring. You hypothesize that these frogs evolved to have more claws as an adaptive trait to improve reproductive success. To test this hypothesis, you must: 1.look for evidence of multiple claws in ancestors of Pipidae 2.determine if the number of claws is heritable 3.test whether other these males have any other adaptive traits 4.test whether males with no claws are able to matearrow_forwardA niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem. Northern Pacific TreeFrog California Red Legged Frogarrow_forwardYou are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators Design an experiment to test the hypothesis that this turtle…arrow_forward
- Adult Daphnia cucullata are aquatic and have two morphs. One has a large “helmet” which makes it harder for their main predator, a type of insect, to eat them. The other lacks the helmet. Female Daphnia keep their eggs within their bodies before hatching. Typically, when mothers are in ponds with their insect predators, their offspring develop helmets, and vice versa. The above scenario best represents an example of a: a.continuous adaptive response b.non-adaptive response c.immediate adaptive response d.predictive adaptive responsearrow_forwardWhich of the following statement(s) is/are true. Select the best overall answer. a. healthy populations of raptors likely have large number of floaters; floaters are sexually mature individuals that do not have a breeding territory. b. McClure et al. note that about 18% of the World's raptors are threatened with extinction, and 13% of all of the World's bird species are threatened with extinction; certain areas of the World, like southeast Asia and sub-Saharan Africa have a greater perentage of imperiled species. c. floater Great Horned Owls tended to be located on the edges of breeding territories of nesting adults, and floater Great Horned Owls tended not to hoot/vocalize in response to broadcast calls of Great Horned Owls d. all of the above e. only a and barrow_forwardShrimp fishing off the coast of Georgia was closed in 2001, due to a drastic reduction in the shrimp population. Landings of blue crab plummeted in 2002 and 2003, as five years of drought and greatly reduced freshwater flow from underground aquifers led to increased salinity in coastal estuaries. These habitats between open ocean and fresh water are “nurseries” for many marine animals. Speculate about possible causes for the decline in shrimp and blue crab populations.arrow_forward
