Definitions for "Intrinsic rate of increase"
A measure of the rate of growth of a population. This is the instantaneous rate of change (per individual per time interval), assuming the population is in stable age distribution. It is equal to the natural log (ln) of the Finite Rate of Increase.
The rate at which a population can grow when its density is low and environmental conditions are highly favorable.
The proportional rate of increase of a population at very low population numbers or biomass where density dependent effects are negligible. It therefore represents the average maximum proportional growth rate of the population.
