| Ecology | The study of living things and the interaction of their environment |
| Abiotic Factor | Nonliving parts of an organisim's environment |
| Air, Temperature, Light, Soil | Abiotic Factor |
| Ecotone | Biome grading areas, areas where biomes overlap |
| Biotic Factors | All the living organisms that inhabit an environment |
| Organismal Ecology | studies an organism’s structure, behavior, and how it meets the challenges of its environment |
| Population Ecology | studies factors that affect how many individuals of a particular species live in an area |
| Community Ecology | studies factors that affect how many individuals of a particular species live in an area |
| Ecosystem Ecology | studies energy flow and chemical cycling among the biotic and abiotic factors |
| Dispersal | the movement of individuals away from their area of origin |
| Distribution | How individuals are spatial arranged |
| Species Transplants | organisms that are intentionally or accidentally relocated from their original distribution |
| zebra mussels, kudzu | Species Transplants |
| Habitat | place where an organism lives |
| Niche | an organism’s role in the environment |
| Biotic Factors that influence habitat selection | species, predation, competition |
| Climate | prevailing weather conditions in an area |
| Macroclimate | climate on a global scale |
| Microclimate | climate encountered communities |
| How do bodies of water influence climate? | Help moderate climate of nearby terrestrial environment |
| Effects of mountains on climate? | Amount of sunlight, local temperature, rainfall |
| Thermal stratification | vertical temperature layering |
| Biannual mixing | spring and autumn winds |
| Turnover | changing water temperature profiles; brings DO water from the surface to the bottom and nutrient rich water from the water from the bottom to the surface |
| Detritus | dead organic matter; food for benthic organisms |
| Littoral zone | well lit, open water close to shore |
| Limnetic zone | well lit, open water further from the shore |
| Profundal zone | deep, aphotic waters |
| Intertidal zone | area where land meets water |
| Pelagic zone | open water of any depth |
| Benthic zone | seafloor bottom |
| Tropical Forests | equator; most complex; constant temperature and rainfall; canopy |
| Savanna | tropical grassland with scattered trees; occasional fire and drought; large herbivores |
| Temperate deciduous forest | midlatitude regions; broadleaf deciduous trees |
| Tundra | permafrost; very little precipitation |
| Population | all the plants or animals of a particular species present in a place |
| Density | the concentration of people or things within an area in relation to its size |
| Dispersion | the scattering or distribution of something within an area or space |
| Mark-recapture method | method for estimating wildlife populations where animals are captured, tagged, and released |
| Immigration | the influx of individuals from other areas |
| Emigration | the movement of individuals out of a population |
| Territoriality | the defense of a bound physical space against encroachment by other individuals |
| Uniform dispersion | animals are territorial and plants secrete acid |
| Random dispersion | absence of strong attractions and repulsions in the species |
| Clumped dispertion | predators that work as teams and strong environmental limitations and factors |
| Demography | study of the vital statistics of populations and how they change over time |
| Life tables | age-specific summaries of the survival pattern of a population |
| Survivorship | a plot of the proportion of numbers in a cohort still alive at each age |
| Reproductive table | age-specific summary of the reproductive rates in a population |
| Life history | the traits that affect an organism’s schedule of reproduction and survival |
| Semelparity | A life history in which adults have but a single reproductive opportunity to produce large numbers of offspring |
| Iteroparity | reproducing more than once in a lifetime |
