362131740 | Homeostasis | process by which organisms maintain a relatively stable internal environment | |
362131741 | Allen's Rule | states that endotherms from colder climates usually have shorter limbs (or appendages) than the equivalent animals from warmer climates. | |
362131742 | Population | a group of organisms of the same species populating a given area | |
362131743 | Population Range | The difference between the upper and lower population quartiles. | |
362131744 | Random Spacing | individuals do not interact strongly with one another; not common in nature | |
362131745 | Uniform Spacing | behavioral interactions; resource competition | |
362131746 | Clumped Spacing | The most common pattern of dispersion, with individuals aggregated in patterns of favorable conditions | |
362131747 | Metapopulations | A network of distinct populations that interact with one another by exchanging individuals. | |
362131748 | Source-Sink Metapopulations | the theory that proposes that populations existing in better habitats (source) serve to bolster populations in poorer areas (sink) | |
362131749 | Demography | Study of populations | |
362131750 | Generation Time | Average interval between the birth of an individual and the birth of its offspring | |
362131751 | Cohort | Group of individuals of the same age | |
362131752 | Fecundity | Number of offspring produced in a standard time | |
362131753 | Mortality | the ratio of deaths in an area to the population of that area | |
362131754 | Age Structure | proportion of people in different age groups in a population | |
362131755 | Life Table | an age-specific summary of the survival pattern of a population | |
362131756 | Mortality Rate | the number of deaths per thousand | |
362131757 | Survivorship | Percentage of the original population that survives to a given age | |
362131758 | Survivorship Curve | Graph showing the number of survivors in different age groups for a particular species. | |
362131759 | Cost of Reproduction | the total physical and energetic costs of reproduction, including nest or territory defense, mating, and producing and raising young. | |
362131760 | Semelparity | A life history in which adults have but a single reproductive opportunity to produce large numbers of offspring, such as the life history of the Pacific salmon; also known as big-bang reproduction. | |
362131761 | Iteroparity | A life history in which adults produce large numbers of offspring over many years; also known as repeated reproduction. | |
362131762 | Biotic Potential | Rate at which a population of a given species increases when no limits are placed on its rate of growth | |
362131763 | Carrying Capacity | Maximum amount of individuals an environment can support | |
362131764 | Sigmoidal Growth Curve | an S-shaped pattern of population growth, with population size leveling off at the carrying capacity of the environment. | |
362131765 | Density-Dependent Population Factors | competition for resources, territoriality, disease, predation, toxic wastes, intrinsic (physiological) factors | |
362131766 | Density-Independent Population Factors | Natural Disasters, Weather | |
362131767 | Density Dependent Effects | the population rates increase or decreases based on the population size | |
362131768 | Allee Effect | Growth rates increasing with population increases(Endangered Species/Isolated Species/Manifest Destiny) | |
362131769 | Density-Independent Effects | the population rates increase or decrease is limited by something other than population size | |
362131770 | K-Selected | Populations adapted to thrive when near the carrying capacity | |
362131771 | R-Selected | Resources high, selection favors individuals with high reproductive rates | |
362131772 | Population Pyramid | A bar graph representing the distribution of population by age and sex. | |
362131773 | Ecological Footprint | A way of measuring how much of an impact a person or community has on the earth. Someone who uses more natural resources will have a bigger footprint than someone who uses less. |

Need Notes?
While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
