| phenomena that takes place on a local scale | |
| population growth that produces a j-shaped pattern of population increase | |
| symbolized as r, equals per capita birthrate minus per capita death rate | |
| phenomena of a geographic scale rather than a local scale | |
| line that best fits the relationship between 2 variables, x and y | |
| a group of individuals that are physically distinctive and engage in specialized behavior within a social unit, such as a colony | |
| abiotic factors in the environment, such as floods and extreme temperature | |
| a population in which the the proportion of individuals in each age class is constant | |
| the actual niche of a species whose distribution is restricted by biotic interactions such as competition, predation, disease, and parasitism | |
| k; the maximum population of a species that a particular ecosystem can sustain | |
| maximum per capita rate of population increase; may be approached under ideal environmental conditions for a species. | |
| sex that produces larger, more energetically costly gametes (eggs or ova) | |
| a portion of a larger population, with which it sustains a connection through immigration and emigration | |
| the total number of individuals, or biomass, of a species present in a specified area | |
| a group of spatially separated subpopulations connected by active exchange of individuals among subpopulations | |
| sex that produces smaller, less costly gametes (sperm or pollen) | |
| biotic factors in the environment, such as disease and competition | |
| increase in animal feeding rate, which eventually levels off, that occurs in response to an increase in food availability | |
| increasing the complexity of the environment of captive animals to foster behaviors characteristic of the species in the wild | |
| lambda; ratio of the population size at 2 points in time | |
| an s-shaped pattern of population growth, with population size leveling off at the carrying capacity of the environment | |
| Study of the relationships between organisms and environment that are mediated by behavior | |
| the physical conditions under which a species might live, in the absence of interactions with other species | |
| population growth in which generations do not overlap and in which successive generations differ in a size by a constant ratio | |
| selection in which individuals increase their inclusive fitness by helping increase the survival and reproduction of relatives that are not offspring | |
| 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 | |
| active or passive downstream movement of stream organisms | |
