- You've been out in the field collecting data on the predation of holly leaves. You collect 200 leaves in total of which 100 leaves contain one mine, 20 leaves contain 2 mines and 30 leaves contain 3 mines. After close examination with your hand lens and dissecting microscope you categorize a total of 15 mines with round holes, 9 mines that were torn open and 27 mines with an irregular hole. After some basic analyses you conclude that the predation rates by blue tits and wasps are: A. 3.7% and 6.5% B. 6% and 10% C. 10% and 6% D. 4% and 6.5%What is often true of a population of organisms with a type Il suvivorship curve? they produce few offspirng and invest more energy in each offspring they produce more offspring and invest little energy in each they have low death rates during early life stages they are equally likely to die at any ageMclver 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.
- Calculate the rate of population change for a hypothetical population of wildebeest using the logistics equation and carrying capacity equation. How can you explain these results? N = 500, r = 0.1, K = 1000, calculate dN/dt.Interpret the following graphs: In the graphs, the number of days are 18.. 1 day is equal to 60 sec. For the first graph, days are taken on x-axis. The mean foraging times are taken on y-axis. For the 2nd graph, percentage of prey caught during first half of winter(1-6days) were taken on x-axis and percentage of prey caught during 2nd half of winter(7-12days) were taken on y-axis.Do the above hypothesis support the graph? Explain Foraging in a mixed-species flock scenario, the assumption is that the establishment of mixed-species flocks will enhance feeding productivity.

Based on the graph, determine the population of carabao in: iii. 6 years:4. What is the maximum carrying capacity of carabao in the given ecosystem? 5. How many years did it take for the carabao to reach its carrying capacity? Explain your answerUse the following information to answer the next question. Predator-prey population cycles prey predator Time Сорy Look Up Share... In the above graph, the points A, B, C, and D represent the following events, in random oraer. 1. Reduction in predator population 2. Reduction in prey population 3. Increase in predator population 4. Increase in prey population The correct order for listing the events represented by A, B, C, and D is » and NumberThe lotka-volterra equation that describes rate of change in the predator population doesn't include intrisic rate for predators. How does it accomodate for growth in predators if the rate is missing?
- Mark Recapture can be written as M N = R Define each term. Use this equation to answer the following question. Show your work. A biologist for Mosaic fertilizer company catches 26 Florida scrub jays as part of their monthly environmental monitoring. Each bird is given a band. The next month, they catch 32 birds. 13 of the birds have bands. What is the estimated population size of the birds in that area?Two winters ago, a species of bird called the pine siskin began appearing in droves at backyard bird feeders in my hometown. We would occasionally spot a few each winter, but numbers were unusually high that year. The next winter, it seemed as if all of the "extra" pine siskins had disappeared. Numbers fell back to the levels that we were used to seeing. Use the concept of carrying capacity to explain the irruption of pine siskins described in the scenario. Provide your answer in a standard paragraph using complete sentencesA population grows according to the logistic model N = 55 1 + 0.9e−1.4t , where t is measured in years and N is measured in thousands. (a) What is r for this population? per year(b) What is the environmental carrying capacity K? thousand(c) This population is subject to harvesting. What is the optimum yield level? thousand
