Kudu Scenano Kudu are an antelope species found in eastem and southem Africa. Maie kudu have dramatically apiraled homa, which makes them a target of trophy huntera. Begin by setting up the following parametera: 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 of t to 50. 25. At what time (T value) do kudu populations reach their carying capacity. given these parameters? 20. What happens to the growth rate of a kudu population as it gets closer and closer to its carrying capacity? 27. What sorts of environmental changes might cause k to increase in this environment?

Question
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
(from #21) to what you'd see with this new value.
29. Although logistic models can be more realistic than exponential models, they still do not perfectiy
capture all aspects of population growth. Can you think of some additional details that impact
population growth that these simple logistic models do not capture?
