Kudu Scenario Kudu are an antelope species found in easterm and southerm Africa. Male kuou have dramatically spiraled homs, which makes them a target of trophy hunters. Begin by setting up the following parameters: k= 100, r= 0.26, N, = 10. Use the gear icon to adjust the min & max values of N, and k to 2 and 200, respectively. Set the max value oft to 50. 25. At what time ("T value) do kudu populations reach their carrying capacity, given these parameters? 28. What happens to the growth rate of a kudu population as it gets closer and closer to its carrying сарacity? 27. What sorts of environmental changes might cause k to increase in this environment? What might cause k to decrease? 28. Trophy hunters move into the area, leading to an increased death rate, which decreases the growth rate rto 0.13. Exolain how this change will impact the population growth patten. [Hint Look at when the population now reaches its carrying capacity, given this decrease in r. Compare your original curve…
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.

Use Verbal description of results from graph and then Interpret the graph for Foraging in Mixed Species Flocks sccenario in foraging lab. The interpretations must include Were the results expected and Did they support the hypotheses? If so, state the biological significance of the results from graph. If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis: the assumption underscores the enhancement of foraging efficiency associated with the establishment of mixed-species flocks, emphasizing the advantages of cooperation and safety in numbers.
What would it mean if apredator removal experiment yielded theopposite results from those shown in Figure 54.5—that is, numbersof surviving moths increased where predators were not removed?
If you adjust each of the four constants, one at a time, by 10%, which seems to have the greatest impact on the simulation output? Examine the Lotka-Volterra equations to explain by this constant makes such a big difference in the predator-prey system. Hint: This constant affects both the birth rate of predators and the death rate of prey.
What are three aspects of your lifestyle that might directly or indirectly contribute to declines in European honeybee populations and the endangerment of other pollinator species (Core Case Study)?
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.

A population of boreal toads has a current size of 100 and time steps are measured in years. If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.
The relationship between predator and prey populations has been studied by computer simulation using equations which form part of a mathematical model devised by Lotka and Volterra. The data in Table 6.10 show the results of such a simulation when the prey population begins with 20 individuals and the predator population begins with six individuals. 1.Explain why the peaks in the predator population occur after those in the prey population. 2. This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations. Why is it likely to be too simplistic to describe accurately what happens in nature?
