Oceanography
Chap 16
| Question | Answer |
|---|---|
| Biodiversity | The variety of different species within a habitat |
| Brackish | Describing water intermediate in salinity between seawater and freshwater |
| Carrying Capacity | The size at which a particular population in a particular environment will stabilize when its supply of resources- including nutrients, energy, and living space-remains constant |
| Climax Community | A stable, long-established community of self-perpetuating organisms that tends not to change with time |
| Clumped Distribution | Distribution of organisms within a community in small, patchy aggregations, or clumps; the most common distribution pattern |
| Commensalism | A symbiotic interaction between two species in which only one species benefits and neither is harmed |
| Deep Scattering Layer (DSL) | A relatively dense aggregation of fishes, squid, and other mesopelagic organisms capable of reflecting a sonar pulse that resembles a false botton in the ocean. Its position varies with the time of day |
| Desiccation | Drying |
| Ecology | Study of the interactions of organisms with one another and with their environment |
| Environmental Resistance | All the limiting factors that act togethr to regulate the maximum allowable size of carrying capacity of a population |
| Estuary | A body of water partially syrrounded by land where fresh water from a river mixes with ocean water, creating an area of remarkable biological productivity |
| Euryhaline | Describing an organism able to tolerate a wide variance in salinity |
| Eurythermal | Describing an organism able to tolerate a wide variance in temperature |
| Extremophile | An organism capable of tolerating extreme environmental conditions, especially temperature of pH level |
| Habitat | The place where an individual or population of a given species lives, its "mailing address" |
| Intertidal zone | The marine zone between the highest high-tide point on a shore line and the lowest low-tide point. |
| Motile | Able to move about |
| Mutualism | A symbiotic interaction between two species that is beneficial to both |
| Niche | Description of an organisms functional role in a habitat;its job |
| Parasitism | A symbiotic relationship in which one species spends part or all of its life cycle on or within anotherm using the host species (or food within the host species) as a source of nutrients; most common source of symbiosis |
| Population | A group of individuals of the same species occulpying the same area |
| Population Density | The number of individuals per unit area |
| Random Distribution | Distribution of organisims within a community whereby the position of one organism is in no way influenced by the positions of other organisms or by the physical variations within that community; a very rare type of distribution pattern |
| Sessile | Attatched; nonmobile; unable to move about |
| Species-specific relationships | An exclusive relationship betwee two species; parasites are usually species-specific in that they can usually only parasitize one species of host |
| Stenohaline | Describing an organism unable to tolerate a wide range in salinity |
| Stenothermal | Describing an orgamism unable to tolerate a wide range in temperature |
| Succession | The changes in species composition that lead to a climax community |
| Symbiosis | The co-occurrence of two species in which the life of one is closely interwoven with the life of the other; mutualism, commensalism or parasitism |
| Uniform distribution | Distribution of organisms within a community characterized by equal space between individuals(the arrangement of trees in an orchard); the rarest natural distribution pattern |
| Wave shock | Physical movement, often sudden, violent, and of great force, caused by the crash of wave against an organism |
