Learn about the dynamics of species populations and how they interact with the environment, such as birth and death rates, and immigration and emigration. Explore the history, terminology, and models of population ecology, and its applications in conservation biology and fisheries and wildlife management.
The Leslie matrix is a discrete, age-structured model of population growth that is widely used in population ecology. It describes the changes in a population over time based on vital rates such as survival and fecundity, and has a stable age distribution and growth rate.
The source–sink model of population dynamics has made contributions to many areas in ecology. For example, a species' niche was originally described as the environmental factors required by a species to carry out its life history, and a species was expected to be found only in areas that met these niche requirements.

Ecology is the natural science of the relationships among living organisms and their physical environment. It covers various levels of organization, from genes to ecosystems, and has practical applications in conservation, resource management, and human ecology.
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment. The web page does not mention any animal commonly used for carrying supplies, but it explains the concept of carrying capacity in ecology, agriculture and fisheries.
Ecosystem ecology is the study of living and non-living components of ecosystems and their interactions. Learn how ecosystems work, how they are affected by climate, disturbance, and management, and how they provide essential services to human societies.
An ecotype is a genetically distinct and adaptive variant of a species that is adapted to specific environmental conditions. Learn how ecotypes are related to morphs, clines, and speciation, and see examples of ecotypes in plants, animals, and humans.
Learn what a community is in ecology, how it is composed of populations, niches, trophic levels, guilds, and influential species. Explore the factors that affect community structure, diversity, and function, such as abiotic conditions, human activities, and foundation species.
