Population Ecology

the maximum number of individuals in a species that an environment can support for the long term

• biodiversity
• ecosystem
• carrying capacity
• population density

the number of organisms per unit area

• population growth rate 

• population dispersion

• carrying capacity

• population density

the number of individuals moving into a population

• population

• immigration

• dispersion

• emigration

pattern of spacing of a population within an area

• population density
• population dispersion
• density-dependent factor

• carrying capacity

the number of individuals moving away from a population

• immigration
• population density 

• emigration
• population growth

speed at which a population grows

• population density

• population distribution
• population size

situation in a population in which birth rate equals death rate

• age structure

• demographic transition

• demography

in a population, the number of males and females in each of three age groups: pre-reproductive stage, reproductive stage, and post-reproductive stage

• zero population growth (ZPG)

the study of human population size, density, distribution, movement, birthrates, and death rates
