Population ecology

Ecological study that focuses on a population, which is all individuals of one species inhabiting the same geographic area.

Population

All individuals of one species that inhabit the same geographic area and can interbreed.

Logistic growth

A model for predicting population change over time, considering carrying capacity and resource availability.

Carrying capacity (K)

The maximum population size that the environment can support.

Density-dependent factor

An ecological factor whose impact increases with population density, affecting population growth and resource availability.

Density-independent factor

An ecological factor whose impact is unrelated to population density, often an abiotic factor such as natural disasters.

r-selected strategy

A life history strategy characterized by high fecundity and low survivorship, leading to rapid population growth.

K-selected strategy

A life history strategy characterized by low fecundity and high survivorship, with population growth regulated near carrying capacity.

Metapopulation

A population of smaller populations, partially separated by unsuitable habitat, but connected by migration.

Maximum sustainable yield (MSY)

The maximum population growth rate that allows for sustainable harvesting without long-term population decline.
