- 1PopulationA group of individuals of a single species living in the same general area
- 2DensityNumber of individuals per unit area or volume
- 3DispersionThe pattern of spacing among individuals within the boundaries of the population
- 4ImmigrationThe influx of new individuals from other areas
- 5EmigrationThe movement of individuals out of a population and into other locations
- 6TerritorialityThe defense of a bounded physical space against encroachment by other individuals
- 7DemographyThe study of the vital statistics of populations and how they change over time
- 8Life TableAge-specific summary of the survival pattern of a population
- 9CohortA group of individuals of the same age, from birth until all of the individuals are dead
- 10Survivorship CurveA plot of the proportion or numbers in a cohort still alive at each age
- 11Reproductive TableAn age-specific summary of the reproductive rate in a population
- 12Exponential Population GrowthWhen the instantaneous per capita rate of increase is greater than zero and is constant at each instant in time
- 13Carrying CapacityThe maximum population size that a particular environment can sustain
- 14Logistic Population GrowthWhen the per capita rate of increase approaches zero as the population size nears the carrying capacity
- 15Life HistoryThe traits that affect an organism's schedule of reproduction and survival
- 16SemelparityWhen an organism reproduces only once
- 17IteroparityWhen an organism reproduces more than once
- 18K-selectionSelection for traits that are sensitive to population density
- 19r-selectionSelection for traits that maximize reproductive success in uncrowded environments
- 20Density IndependentWhen a birth or death rate does not change with population density
- 21Density DependentWhen a death rate increases with or a birth rate decreases with population density
- 22Population DynamicsSize fluctuations in population from year to year or place to place
- 23MetapopulationWhen a number of local populations are linked
- 24Demographic TransitionThe movement from high birth and death rates towards low birth and death rates, which tends to accompany industrialization and improved living conditions
- 25Age StructureThe relative number of individuals of each age in the population
- 26Ecological FootprintThe aggregate land and water area required by each person, city, or nation to produce all the resources it consumes and to absorb all the waste it generates
