Population ecology is the area of ecology involving population dynamics of various species and its link and relationship with habitat. It would involve all factors that influence the size, density, distribution, and structure of a population in the course of time. This area is crucial in figuring out complicated relationships between organisms and their habitats and necessary in conservation and resource management.

Population ecology focuses mainly on growth, which is regulated by the birth rate and death rate, immigration, and emigration. Population growth curves are often categorized with various types of equations, such as logistic growth. This model takes into account carrying capacity, or the maximum number of members an environment is able to carry. Carrying capacity is determined by existing resources, space, and environmental conditions.

Population ecologists also quantify population density, the number of individuals per unit area or volume. High densities increase the level of resource-and perhaps mate-competition. Low density can reduce reproductive success. Distribution patterns-how individuals are arranged within a habitat-are either uniform, random, or clumped, each with different ecological implications.

It also elaborates on interactions between populations with their environment, such as predation, competition, and symbiosis. All these are integral to the prediction of population responses to environmental changes and how measures for its conservation could be effective.
