- In the Lotka-Volterra predator-prey model, the term for the rate of prey capture as a function of prey abundance is a. exponential response O b. functional response С. numerical response O d. logistic responseWhat is the best description of the original Lotka-Volterra predator-prey model? Nis prey, P is predator. a is rate of consumption, f is conversion of prey to predator, and q is the mortality rate of the predator. dP rN - aNP= = faNP - qP dt dt Type 1 functional response with density-dependent prey and density- independent predator Type 1 functional response with density-independent prey and density- independent predator Type 1 functional response with density-dependent prey and density-dependent predator Type 1 functional response with density-independent prey and density- dependent predatorConsider the predator-prey model dN N cN P 6. dT K a + N dP b N P тР. dT a + N Analyze and discuss the effects of the parameter 0 on the occurrence of limit cycles for the above predator-prey model. Explain how resolve the biological control paradox. your results
- 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.Conflicts in an encounter are necessary to gain a valuable resource at the cost of risking serious injury. In repeated hawk-dove situations wherein neither player can guess who is the hawk or the dove, a strategy can occur that is somewhat more stable compared to other strategies in which - A. Each player can be combative and play the hawk in every encounter. B. Each player will avoid any subsequent encounter with the other. C. Each player can be the hawk some fraction of the time and a dove the rest of the time. D. Each player can be defensive and play the dove in evey encounter.(A) G = rN K – N) (В) K (C) (х-аxis) Question: What does the dotted line represent? O a. carrying capacity O b. plateau ability O c. log phase O d. lag phase (y-axis)
- Great white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)Thinking about the Lotka-Volterra predator-prey model, what effect should an increase in searching efficiency (a) have on the maximum prey population? Increase Decreasė No change < Previnus V Finish5) According to the optimal foraging theory, which of the following is NOT one of the factors that influence the likelihood of a predator's selecting a prey type? Question 5 options: search time required to find alternative prey types profitability of the prey type handling time energy content probability of their own predation
- The yellow perch is a fish found in freshwater lakes. It is a generalist predator, consuming a variety of prey species, including crayfish, small fish, insect larvae and snails. You examine the predation rate of yellow perch on snails, and obtain the following data. Identify the type of functional response, and a plausible reason for why it has that type of response. 60- 40- 20- Perch Predation RateWhich of the following statements about functional response curves is FALSE? O Under Type 3 curves, food intake increase slowly at the lowest prey densities O Type 2 curves can arise when there is substantial handling time involved in capturing and eating prey. O Type 1 curves are the most common found in nature. O For all functional response curves, food intake becomes limited by internal factors at high prey densities.With respect to the Lotka-Volterra predator-prey model, which of the following statements is most likely true? Under this model, it is possible for a predator to drive its prey to extinction. All of the statements are true. Non of the statements is true. This model predicts neutrally-stable predator-prey cycles, as opposed to a stable equilibrium. O In this model, an increase in searching efficiency (a) will increase the maximum prey population.
