Population Dispersion

Spacing pattern refers to the arrangement of individuals within a population.
The most common pattern is clumped dispersion, where individuals aggregate in patches.

Population Density

Density-dependent factors are factors that influence population density and change with population size.
Density-dependent factors have an amplified effect as the population increases and diminish as the population decreases.

Life History Traits

K-selection is characterized by long lifespans, large body size, late reproduction, and few offspring.

Environmental Impacts

Environmental conditions heavily influence population density. Favorable conditions, like ample resources, lead to higher densities, while unfavorable conditions lead to lower densities.

Population Regulation

Mutualism, a type of organism interaction, helps regulate population size by reducing death rates.

Competition and Population Size

Small populations experience less competition, while large populations face intensified competition for resources.

Demography

Demography is the study of population dynamics, age structure, growth, and distribution.

Fertility Rate

Total fertility rate (TFR) signifies the average number of children a woman is expected to have in her lifetime.

Reproductive Strategy

Humans are categorized as K-selected species, characterized by slow reproduction rates and long lifespans.

Replacement-Level Fertility

Replacement-level fertility is the average number of children a couple needs to have to maintain a stable population size.

Explore the concept of dispersion patterns in population ecology, including clumped, uniform, and random patterns. Learn how these patterns indicate habitat or interaction preferences among individuals within a population.
