| Non-living. | ||
| A pattern of growth that increases at a constant amount per unit time, such as 1,2,3,4, or 1,3,5,7. | ||
| Pertaining to life; environmental factors created by living organisms. | ||
| The maximum reproductive rate of an organism, given unlimited resources and ideal environmental conditions. | ||
| The maximum number of individuals of any species that can be supported by a particular ecosystem on a long-term basis. | ||
| A population founded when just a few members of a species survive a catastrophe event or colonize new habitat geographically isolated from other members of the same species. | ||
| A sudden population decline; also caled a population crash. | ||
| The movement of members from a population. | ||
| All the limiting factors that tend to reduce population growth rates and set the maximum allowable population size or carrying capacity of an ecosystem. | ||
| Growth at a constant rate of increase per unit of time; can be expressed as a constant fraction or exponent. | ||
| The physical ability to reproduce. | ||
| Measurement of actual number of offspring produced through sexual reproduction; usually described in terms of number of offspring of females, since paternity can be difficult to determine. | ||
| The effect on a population founded when just a few members of a species survive a catastrophic event or colonize new habitat geographically isolated from other members of the same species. | ||
| The gradual changes in gene frequencies in a population due to random events. | ||
| Growth that follows a geometric pattern of increase, such as 2,4,8,16. | ||
| A population explosion followed by a population crash. | ||
| The study of rates of colonization and extinction of species on islands or other isolated areas based on size, shape, and distance from other inhabited regions. | ||
| A growth curve that depicts exponential growth; called such because of its shape. | ||
| The average age that a new-born infant can expect to attain in a particular time and place. | ||
| The longest period of life reached by a type of organism. | ||
| Growth rates regulated by internal and external factors that establish an equilibrium with environmental resources. | ||
| A collection of populations that have regular or intermittent gene flow between geographically separate units. | ||
| The number of individuals needed for long-term survival of rare and endangered species. | ||
| Death rate in a population; the probability of dying. | ||
| The production of new individuals by birth, hatching, germination, or cloning. | ||
| The extent to which a population exceeds the carrying capacity of its environment. | ||
| A sudden population decline caused by predation, waste accumulation, or resource depletion; also called a dieback. | ||
| Growth of a population at exponential rates to a size that exceeds environmental carrying capacity; usually followed by a population crash. | ||
| A curve that depicts logistic growth; called such because of its shape. | ||
| Diseases caused or accentuated by social stress such as crowding. | ||
| The percentage of a population reaching a given age or the proportion of the maximum life span of the species reached by an individual. |
