11. Match each of the following scenarios to the Hardy-Weinberg condition that is not being met: An increase in antibiotic resistance among bacteria exposed to antibiotics occurs. Caribou from one herd move to a new area and breed with caribou of a completely different herd. Among eastern bluebirds, more brightly coloured males breed with more brightly coloured females. Due to overhunting, there is little genetic diversity in the current population of bearded vultures, which have all descended from a population of only 36 birds.

Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consistingof 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there isno migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E.Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygoteshave shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggyindividuals, and 84 rough individuals.a)What is the size of the population?b)Do the alleles have a simple dominance relationship? Describe.c)What are the frequencies of the two alleles?d)Is the population in Hardy-Weinberg equilibrium?If not, how do you know, and what might be the cause?

1. Hunting is one way of reducing population size. Wildlife managers closely watch changes in population numbers of all wildlife species in order to determine legal hunting ‘bag limits’ for each hunter. Depending on changes in population size, hunting bag limits are changed from year to year. In each of the following scenarios, suggest what changes might have occurred in the population in the previous year to warrant these changes in bag limits. (Address all four factors that affect population size.) a.) The mallard duck bag limit has increased from four ducks/day to eight ducks/day. b.) The previous year 1 female black bear could be taken, and up to 3 males could be taken. This year no females can be taken.
In 1956, two Corsican mouflon sheep were introduced to Haute Island, which has an area of 7.00 km^2. In 1957, the pair were able to reproduce for the first time. By 1977, the population had grown to 600 sheep due to abundant food sources and the lack of natural predators in the area. Since then, the Haute Island sheep population has fluctuated between 200 sheep and 600 sheep. In 1990, 250 mouflon sheep were relocated from Haute Island to a neighbouring island with similar terrain, soil, vegetation and weather patterns. The neighbouring island has an area of 10.0 km^2. 1. Compare the density of the Corsican mouflon sheep population on Haute Island in 1977 with the neighboring island in 1990. (three sig digits) 2. Explain how the growth of the Corsican mouflon sheep population on Haute Island caused interspecific competition ? 3. What prevented the Haute Island sheep population from increasing beyond 600 sheep? 4. What was the growth rate of the Corsican mouflon sheep population on…

1.In wildlife management, population numbers must be sustainable in that populations cannot exceed the environment’s ability to support them. Using the ∆N formula, consider the following: Coyotes are members of the Canis family, or dog family, that wanders natural or agricultural grasslands and temperate forest in search of rodents and small prey. Occasionally they will form packs to bring down a larger animal – perhaps a young, sick, or old deer. In this scenario, assume population numbers of coyotes have increased dramatically. a.Using your knowledge of the ∆N formula, provide four possible causes for this dramatic increase in population. b.Assume you are a wildlife manager and that the high coyote population is resulting in more human/coyote interactions. Steps need to be taken to correct the imbalance in coyotes. Provide two ecologically sound solutions to the problem.
Mclver beetles come in three colors: black, white, and brown. They are consumed by the Foust finch. To avoid predators, the beetles hide on the bark of trees in their environments. If the number of trees with black bark was significantly greater than the number of trees with white or brown bark, what would be the effect on the predation of Mclver beetles by the Foust finches? Far fewer black beetles would I + Which of the five conditions of Hardy-Weinberg equilibrium would be violated in this situation? V [ Select ] Genes are now mutating. Mating is no longer random. The population size is now much larger. The population would experience natural selection pressures. There is now immigration of individuals into the population.

Based on your table, would a species that provides long-term parental care and has few offspring be considered an r-selected or K-selected species? What is an example of such a species? 6c. Why is long-term parental care associated with having few offspring during a reproductive episode?
