We perform this normalization to show that the value of the carrying capacity doesn't play an important role in determining the dynamics. If the carrying capacity had been a number other than , we could have divided by that number, and the end result would be the same equation.
You can click the equilibria to see the tangent lines. A plot showing the equilibria for logistic growth with harvesting. The two equilibria, which are the intersections between the curves, are shown by the blue and green points.
More information about applet. If our objective is to maximize the harvest, we don't want to harvest so much that the population is tiny. Of course, this wouldn't be good from an ecological point of view, either. Since the increasing the harvest rate will decrease the population size, it's not so simple to see what the optimal harvest rate should. Home Threads Index About.
