Key Concepts

Intrinsic Rate of Increase

This concept refers to the maximum potential per capita growth rate of a population, calculated as the difference between birth and death rates under ideal conditions with unlimited resources. It represents the inherent ability of a population to grow when there are no density-dependent restrictions.

Environmental Carrying Capacity

This is the maximum number of individuals that an environment can sustain over time without degradation of resources. When a population is well below this limit, density-dependent factors such as competition for resources minimally impact growth, allowing the population to approach its intrinsic rate of increase.

Density Dependence

Density dependence describes how population growth rates change as a function of population density. At low densities, individuals have more access to resources leading to growth rates that approximate the intrinsic rate of increase, whereas at high densities, competition and other factors slow down growth.
