Two ways of estimating this quantity are the Lincoln-Peterson method and the marked recapture method.
The Leslie Matrix was developed to give the rate of change of this quantity. The rate of change of this quantity is given by the Verhulst Equation. Two ways of estimating this quantity are the Lincoln-Peterson method and the marked recapture method. Two different values of this quantity are the independent variables in the coupled Lotka-Volterra differential equations. This quantity approaches its highest sustainable value in organisms exhibiting K-selection. The upper bound for this quantity is known as the carrying capacity. For 10 points, name this ecological quantity, which for humans on earth is around 7 billion.
