Cactus Corner Desert Valley 20 • Short horns O Long horns 0. 6. 12 12 Weeks Weeks The hypothesis that longer horns offer greater protection against predation is supported. • The hypothesis that longer horns offer greater protection against predation is NOT supported. The experiment is well designed, but the results are inconclusive about the hypothesis. The experiment is not well designed to test the hypothesis. MacBook Pro Surviving Lizards 20African hunting dogs depend on sustained chases by groupsof cooperating individuals to capture antelopes for food. If themembers of two groups differ in their average V•O2max, how mightthe two groups differ in the strategies they use during hunting?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…

Activities of these nonbreeding helpers includeincubating eggs and defending stashed acorns. Propose somequestions about the proximate and ultimate causation of thesebehaviors that a behavioral biologist could ask.What 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 predatorUse 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.
