 A population's vital statistics (e.g. size, distribution, density, age structure) demographics Number of individuals making up a population population size Of a population, distribution of individuals among different age categories age structure all individuals of a population that are in the pre-reproductive and reproductive age brackets reproductive base Number of individuals making up a population population density pattern of dispersion of individuals of a population population distribution one of many areas of a given size and shape in which samples are taken of individuals of a population are counted Quadrats For population counts; collecting, marking, releasing, then recapturing representitive animals capture-recapture methods New individuals permanently move into an area immigration individuals leave a population emigration recurring movement of organisms from one region to another, then back migration no overall increase or decrease in population size during a specified interval zero population growth per individual per capita for population growth equations, a variable combining birth rates and death rates; assumes that both remain constant in specified interval net reproduction per individual per unit time an increase in population size by a fixed percentage of the whole in a given interval exponential growth length of time it takes a population to double in size doubling time the maximum rate of increase of a population under ideal conditions biotic potential any essential resource that can halt population growth when supplies of it dwindle limiting factor the maximum number of individuals in a population (or species) that a given environment can sustain indefinitely carrying capacity the size of a population increases slowly, then rapidly, then levels off as the carrying capacity is reached logistic growth factor that operates at high population density to slow birth rate and/or increase death rate (disease, competition) density-dependent controls factor that impacts a population's birth rate or death rate regardless of density (fire or flood) density-independent factor adaptations affecting life span, fertility, and age at first reproduction life history pattern a group of smae-aged individuals, tracked throughout their life spans cohort a graph that reflects how many individuals of a cohort survive, on average, at successive ages in their life span survivorship curve TFR, w/in a population, the average number of children born to a woman during her reproductive years total fertility rate explanation of the effects of industrialization on human population growth demographic transition model
