Logistic equation of population growth
WitrynaThe logistic differential equation dN/dt=rN(1-N/K) describes the situation where a population grows proportionally to its size, but stops growing when it reaches the size of K. ... more. So I get the addition of a cap on population growth in order to account for carrying capacity. However, isn't there also a necessity to include some form of ... Witryna8 cze 2024 · The formula we use to calculate logistic growth adds the carrying capacity as a moderating force in the growth rate. The expression “K – N” is indicative of how many individuals may be added to a population at a given stage, and “K – N” divided by “K” is the fraction of the carrying capacity available for further growth.
