Populations Mr. Haase

What is a population? All members of a species living in the same place at the same time

Properties of Populations Density- number of individuals per unit area Dispersion- arrangement of individuals in given space

How do you measure population growth? Change in Population size = Births - Deaths

Reproductive Potential Maximum number of offspring each member of a population can produce

Exponential Growth

What limits overpopulation? Carrying capacity- maximum population an ecosystem can support

Factors that limit population growth Resource Limits Competition

Population Regulation Density Dependant When deaths occur more quickly in crowded populations Examples: Black Plague Pine Beetle Density Independent Deaths occur regardless of population density Examples: Severe Weather Natural Disasters
