| 8644857880 | population ecology | study of populations in relation to their enviornment | 0 | |
| 8644857881 | population | group of individuals of a single species living in the same general area, all rely on same resources, influenced by similar environmental factors and usually breed and interact with one another, boundaries and size | 1 | |
| 8644857882 | density | number of individuals per unit area or volume | 2 | |
| 8644857883 | dispersion | pattern of spacing among individuals within the boundaries of the population, there's uniform, random, and clumped | 3 | |
| 8644857884 | mark-recapture method | tag individuals in 2 different sets to estimate population size | 4 | |
| 8644857885 | immigration | new members of the same species coming IN to a population | 5 | |
| 8644857886 | emigration | members of the same species going OUT of a population | 6 | |
| 8644857887 | territoriality | defense of a bounded physical space against encroachment by others | 7 | |
| 8644857888 | demography | study of vital stats of a pop and how they change over time, birth and death rates | 8 | |
| 8644857889 | life tables | age-specific summaries of the survival pattern of a population, used in insurance companies to find life expectancies | 9 | |
| 8644857890 | cohort | group of individuals of same age | 10 | |
| 8644857891 | survivorship curve | represents some data from life tables, plot of the proportion or numbers in a cohort still alive at each age, 3 types | 11 | |
| 8644857892 | type I curve | Low death rate in young and middle age, but exponentially increasing death rate as the organism becomes old. | 12 | |
| 8644857893 | type II curve | Relatively linear death rate throughout entire life. | 13 | |
| 8644857894 | type III curve | high death rate early in life, but flattens out as organism ages. Usually a product of semelparity. | 14 | |
| 8644857895 | reproductive table | fertility schedule, age-specific summary of the reproductive rates in a population, sexual species tally the number of female offspring produced by each age-group |  | 15 |
| 8644857896 | zero population growth | when the birth rates and death rates equal rach other | 16 | |
| 8644857897 | exponential population growth | pop increase in ideal conditions, per capita rate of increase may assume its max rate and is show as rmax | 17 | |
| 8644857898 | per capita death rate | expected number of deaths per unit of time in a pop of any size, D=MN | 18 | |
| 8644857899 | per capita birth rate | number of offspring produced per unit of time by an average member of the population B=bN | 19 | |
| 8644857900 | carrying capacity | limit of resources, limit to the number of individuals that occupy a habitat, represented by K | 20 | |
| 8644857901 | logistic population growth model | per capita rate of increase approaches zero as carrying capacity is reached, |  | 21 |
| 8644857902 | life history | made up of traits that affect an organism's schedule of reproduction and survival | 22 | |
| 8644857903 | semelparity | one shot at reproduction, "big bang reproduction", usually many | 23 | |
| 8644857904 | iteroparity | repeated reproduction, produce large offspring in fewer quantities | 24 | |
| 8644857905 | k-selection | Selection for life history traits that are sensitive to population density -- aka density-dependent selection. | 25 | |
| 8644857906 | r-selection | selection for life history traits that maximize reproductive success in uncrowded environments -- density independent selection | 26 | |
| 8644857907 | density independent | birth or death rate that doesn't change with pop density | 27 | |
| 8644857908 | density dependent | death rate that rises as pop density rises, birth rate that falls with rising density | 28 | |
| 8644857909 | population dynamics | the branch of science that studies the size and age of populations and the biological and environmental processes driving them. | 29 | |
| 8644857910 | metapopulations | group of spatially separated populations of one species that interact through immigration and emigration | 30 | |
| 8644857911 | demographic transition | movement from high birth and death rates toward low birth and death rates, accompanies industrialization and improved living conditions | 31 | |
| 8644857912 | age structure | relative number of individuals of each age in the pop, often graphed as pyramids | 32 | |
| 8644857913 | ecological footprint | summarizes land and water required by each person, city, or nation to produce all the resources it consumes and to absorb all the waste it generates | 33 |
