Carrying capacity is a commonly used concept for biologists when trying to better understand biological populations and the factors which affect them. When addressing biological populations, carrying capacity can be seen as a stable dynamic equilibrium, taking into account extinction and colonization rates. In population biology, logistic growth assumes that population size fluctuates above and below an equilibrium value. WebBetween 2001 and 2004 the natural growth slows down because the fish population is approaching its carrying capacity. Starting in 2004, the harvest is more than the natural growth. This makes the fish population go down. But because the fish population is close to the carrying capacity, reducing the fish population makes its growth rate go up! WebFeb 18, 2016 · Figure 1: with r=0.1 and c=0.1 as parameters, the population experiences a positive but steadily decreasing growth rate because the carrying capacity increases at 1/10th the rate of population growth, and since population growth slows as the population size approaches the carrying capacity, we observe almost asymptotic behavior. irrigation of a foley
