| Population | A group of individuals of a single species living in the same general area |
| Density | Number of individuals per unit area or volume |
| Dispersion | The pattern of spacing among individuals within the boundaries of the population |
| Immigration | The influx of new individuals from other areas |
| Emigration | The movement of individuals out of a population and into other locations |
| Territoriality | The defense of a bounded physical space against encroachment by other individuals |
| Demography | The study of the vital statistics of populations and how they change over time |
| Life Table | Age-specific summary of the survival pattern of a population |
| Cohort | A group of individuals of the same age, from birth until all of the individuals are dead |
| Survivorship Curve | A plot of the proportion or numbers in a cohort still alive at each age |
| Reproductive Table | An age-specific summary of the reproductive rate in a population |
| Exponential Population Growth | When the instantaneous per capita rate of increase is greater than zero and is constant at each instant in time |
| Carrying Capacity | The maximum population size that a particular environment can sustain |
| Logistic Population Growth | When the per capita rate of increase approaches zero as the population size nears the carrying capacity |
| Life History | The traits that affect an organism's schedule of reproduction and survival |
| Semelparity | When an organism reproduces only once |
| Iteroparity | When an organism reproduces more than once |
| K-selection | Selection for traits that are sensitive to population density |
| r-selection | Selection for traits that maximize reproductive success in uncrowded environments |
| Density Independent | When a birth or death rate does not change with population density |
| Density Dependent | When a death rate increases with or a birth rate decreases with population density |
| Population Dynamics | Size fluctuations in population from year to year or place to place |
| Metapopulation | When a number of local populations are linked |
| Demographic Transition | The movement from high birth and death rates towards low birth and death rates, which tends to accompany industrialization and improved living conditions |
| Age Structure | The relative number of individuals of each age in the population |
| Ecological Footprint | The 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 |
