How does the type of density dependence influence population growth under the logistic model? Use graphs from your simulations of the theta-logistic model to demonstrate how the form of density dependence influences growth and where a manager would want to maintain the population for maximum sustained yield. dd(500,.2,1.5,.5) ricker.dd(500,.2,2.5,.25) Observed Growth Rate 0.00 0.10 0.20 # Added 40 80 120 0 0 Linear Weak Strong 200 400 600 Population Size ricker.dd(500,.4,4.5,.5) 0 100 Linear Weak Strong 300 Population Size 500 # Added 20 40 # Added 200 400 0 0 Linear Weak Strong 0 100 300 500 Population Size ricker.dd(800,.75,9,.85) Linear Weak Strong 0 200 400 600 800 Population Size
