| population growth in which generations do not overlap and in which successive generations differ in a size by a constant ratio | |
| a graphical summary of patterns of survival in a population | |
| sex that produces larger, more energetically costly gametes (eggs or ova) | |
| phenomena of a geographic scale rather than a local scale | |
| the geographic range of an organism or the spatial arrangement of individuals in a local population | |
| a distribution of individuals in a population in which individuals are uniformly spaced | |
| an area of population ecology concerned with the factors influencing the expansion, decline, or maintenance of populations, including rates of births, deaths, immigration, and emig | |
| group living generally involving some degree of cooperation between individuals | |
| a pattern of distribution in a population in which individuals have a much higher probability of being found in some areas than in others | |
| increase in animal feeding rate, which eventually levels off, that occurs in response to an increase in food availability | |
| a group of spatially separated subpopulations connected by active exchange of individuals among subpopulations | |
| the total number of individuals, or biomass, of a species present in a specified area | |
| symbolized as r, equals per capita birthrate minus per capita death rate | |
| population growth that produces a j-shaped pattern of population increase | |
| the actual niche of a species whose distribution is restricted by biotic interactions such as competition, predation, disease, and parasitism | |
| phenomena that takes place on a local scale | |
| lambda; ratio of the population size at 2 points in time | |
| sexual selection in which individuals of one sex compete among themselves for mates | |
| a population in which the the proportion of individuals in each age class is constant | |
| results from differences in reproductive rates among individuals as a result of differences in mating success due to intrasexual selection, intersexual selection, or a mixture of t | |
| the environmental factors that influence the growth, survival, and reproduction of a species | |
| a statistic used to measure how much a sample distribution differs from a theoretical distribution | |
| a distribution in which individuals within a population have an equal chance of living anywhere within an area | |
| abiotic factors in the environment, such as floods and extreme temperature | |
| maximum per capita rate of population increase; may be approached under ideal environmental conditions for a species. | |
| a pattern of growth that produces a sigmoidal, or s-shaped, population growth curve | |
