WitrynaWhen resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce, and it levels off when the carrying capacity of the environment is reached, resulting in an S-shaped curve. Source: OpenStax Biology WitrynaA logistic growth function is illustrated in Fig. 1. It is clear from Fig. 1 that the maximum sustainable yield occurs at the maximum growth rate. In other words, it would be possible to maintain a stock of K /2 and harvest at this maximum growth rate in steady state. Figure 1. Logistic growth. View chapter Purchase book

WitrynaA biological population with plenty of food, space to grow, and no threat from predators, tends to grow at a rate that is proportional to the population-- that is, in each unit of time, a certain percentage of the individuals produce new individuals.If reproduction takes place more or less continuously, then this growth rate is represented by Witryna4 gru 2024 · In logistic growth, population expansion decreases as resources become scarce, and it levels off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
