Textbook Question
Chapter 40.4, Problem 2CC
Imagine that you are constructing a life table for a different population of Belding’s ground squirrels (see Table 40.1). If 485 individuals are alive at the start of year 0-1 and 218 are still alive at the start of year 1-2, what is the proportion alive at the start of each of these years (see column 3 in Table 40.1)?

As a hypothetical example, imagine that you were studying a population of Eastern Collared-Lizards (Crotaphytus collaris). The lizards laid 2000 eggs, of which 1000 were eaten by raccoons and skunks. Eight hundred of the surviving juveniles were eaten by foxes and cats. One hundred and eighty of the young adults died during their first hibernation period. What is the indispensable mortality for each stage? If you want to increase the numbers of reproducing adults, which stage should you focus on?
For questions 1-3, suppose that in generation 0, the frequency of allele A1 in a population of armadillos is 0.4. In each generation, 10 percent of the individuals in that population are migrants from another population that has an allele frequency of 0.6.
Calculate the frequency of A1 in each of the next two generations (generations 1 and 2).
What are the allele frequencies?
Hint: Use equation 8.1 to first calculate the change in frequency of allele A1 after generation 1.

- Consider a metapopulation of iguanas inhabiting a chain of small islands off the coast of South America. In year 1, there are iguanas on 15 of the 60 islands. The probability of a given empty island being colonized in a given year is 0.11, and the probability of the population going extinct on any particular occupied island in a given year is 0.12. In year 1, what will be the rate of change in the proportion of islands occupied by iguanas, based on the Levins metapopulation model? Determine the number of islands that should be occupied when the metapopulation reaches equilibrium. Should this metapopulation go extinct, or should it persist? How do you know?arrow_forwardThe following experiment is used for the following question. A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers, but caterpillars that hatch in summer feed on oak leaves and look like oak twigs. How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below.

Over the next several decades, steps were taken to protect turtle nests and prevent accidental killing of turtles at sea by fishing fleets. As a result, the population of leatherbacks nesting on beaches in Florida has been growing exponentially (FIG. E31-3). What factors probably contributed to this exponential growth? Can exponential growth continue? If not,what factors are likely to cause the population to stabilize?arrow_forward
- Suppose that in generation 0, the frequency of allele A1 in a population of armadillos is 0.4. In each generation, 10 percent of the individuals in that population are migrants from another population that has an allele frequency of 0.6. a) Calculate the frequency of A1 in each of the next two generations (generations 1 and 2). b) Is the change in allele frequency in generation 2 greater than, less than, or equal to the change in generation 1?

- There are two color morphs in boomer foxes (not a real species), red and gray. Both tend to have a single litter of 4 pups, and there is little difference in pup mortality or reproductive success between the two morphs. Red morphs tend to have their litter in their second year, and most die before 5 years old. Gray morphs tend to have their litter in their third year and most live to 10 years old. Given this information which of the following statements below is correct? Group of answer choices Gray morphs and red morphs have same relative fitness Given that the gray morphs live twice as long as the red morphs their fitness is greater Since red morphs reproduce first their fitness is greater than gray morphs Since gray morphs delay reproduction their pups are fatterarrow_forwardAfter observing a finite population of asexually reproducing salamanders, which of the following outcomes is consistent with Müller’s ratchet? a.

The population fitness will increase due to the most fit individuals randomly not surviving to produce offspring into the next generation. c. The population fitness will decline due to the most fit individuals randomly not surviving to produce offspring into the next generation. d. The population fitness will increase due to the least fit individuals randomly not surviving to produce offspring into the next generation.arrow_forwardWhat can you infer about bats compared to other mammals?
