Euler-Lotka equation

The Euler-Lotka equation is a mathematical tool used in ecology and population biology to determine if a population is stable, growing, or shrinking. It considers how many new individuals are born at different ages (birth rates) and how long individuals of each age tend to live (survivorship). By balancing these factors with the population's growth rate, the equation helps predict whether the population will increase, stay steady, or decline over time. Essentially, it's a way to link individual life histories with the overall growth trend of a species.
