the geographic area in which a species can be found

the pattern of spacing of a population within an area

the number or organisms per unit area

limiting factors whose influence is not affected by population density (i.e. floods, hurricanes, temperature)

factor that limits a population more as population density increases (i.e. disease, predation, competition)

the number of offspring an individual can produce in a given time period, minus the deaths of the individual or its offspring during the same period

The number of deaths in a population in a certain amount of time (mortality)

the number of live births each year per 1,000 people (natality)

movement of individuals out of a population

Movement of individuals into a population

growth whose rate becomes ever more rapid in proportion to the growing total number or size.

Growth pattern in which a population's growth rate slows or stops following a period of exponential growth

the shape of exponential growth when graphed

the shape of the logistic growth model when graphed

intense activity preparing for population growth, but no increase in population

when the birth rate equals the death rate

Largest number of individuals of a population that a environment can support

number of males and females of each age in a population

The scientific study of population characteristics.

change in a population from high birth and death rates to low birth and death rates
