Textbook Question
Chapter 1.3, Problem 4CC
WHAT IF? Ø In the deserts of New Mexico, the soils are mostly sandy, with occasional regions of black rock derived from lava flows that occurred about 1,000 years ago. Mice are found in both sandy and rocky areas, and owls are known predators. What might you expect about coat color in these two mouse populations? Explain. How would you use this ecosystem to further test the Camouflage hypothesis?

WHAT IF? Suppose two bird species live in a forestand are not known to interbreed. One species feeds andmates in the treetops and the other on the ground. Butin captivity, the birds can interbreed and produce viable,fertile offspring. What type of reproductive barrier mostlikely keeps these species separate in nature? Explain.
WHAT IF? Imagine two populations of a fish species,one in the Mediterranean Sea and one in the CaribbeanSea. Now imagine two scenarios: (1) The populationsbreed separately, and (2) adults of both populationsmigrate yearly to the North Atlantic to interbreed. Whichscenario would result in a greater loss of genetic diversityif the Mediterranean population were harvestedto extinction? Explain your answer.
WHAT IF? Consider two species that diverged whilegeographically separated but resumed contact beforereproductive isolation was complete. Predict the outcome over time if the two species mated indiscriminately and (a) hybrid offspring survived and reproducedmore poorly than offspring from intraspecific matingsor (b) hybrid offspring survived and reproduced as wellas offspring from intraspecific matings.

Simulations 4-6 had lower density of birds (more spacing), how did this influence their ability to escape predation? With more spacing, which number of Junco’s was most advantageous (4, 8, and 16)? Ecologically explain this result. If this flock of birds occurred in an area with low food availability what flock density would you predict? Explain how food availability impacts flock size/competition. Was there a relationship between prop. Vigilance (proportion of birds looking up right before Hawk attack) and the rate at which they escaped predation? Was there a relationship between Mean vigilance (average number of birds looking up each tick) and the rate at which the Junco’s the escaped predation? Was there a relationship between Mean vigilance and the number of birds in the flock?arrow_forwardIntroduction The Rock Pocket Mouse The rock pocket mouse, Chaetodipus intermedius, is a small, nocturnal animal found in the deserts of thesouthwestern United States. Most rock pocket mice have a sandy, light-colored coat that enables them to blendin with the light color of the desert rocks and sand on which they live. However, populations of primarily dark-colored rock pocket mice have been found living in areas where the ground is covered in a dark rock calledbasalt caused by geologic lava flows thousands of years ago. Scientists have collected data from a population ofprimarily dark-colored mice living in an area of basalt called the Pinacate lava flow in Arizona, as well as from anearby light-colored population. Researchers analyzed the data from these two populations in search of thegenetic mutation responsible for the dark coat color. Their analyses led to the discovery of a mutation in theMc1r gene that is involved in coat-color determination. The MC1R Gene Two pigments…arrow_forward

- help me solveCritical Thinking #1 Biol 1406 Group Names:Read the following and fully answer the questions below. Most answers will be multiple sentences or a paragraph in length.Nearly half a century ago, D. W. Kaufman investigated the effect of prey camouflage on predation. Kaufman tested the hypothesis that the amount of contrast between the coat color of a mouse and the color of its surroundings would affect the rate of nighttime predation by owls. He also hypothesized that the color contrast would be affected by the amount of moonlight. In this exercise, you will analyze data from his owl-mouse predation studies.Pairs of mice (Peromyscuspolionotus) with different coat colors, one light brown and one dark brown, were released simultaneously into an enclosure that contained a hungry owl. The researcher recorded the color of the mouse that was first caught by the owl. If the owl did not catch either mouse within 15 minutes, the test was recorded as a zero. The release trials were…arrow_forwardAncestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.arrow_forwardEVOLUTION CONNECTION Explain the biological basis forassigning all human populations to a single species.
