NOAA Coral Reef Conservation Program, National Oceanic and Atmospheric Administration, U.S. Department of Commerce
The deepest seaward part of a coral reef; a vertical cliff beginning at a depth of about 60 m.
Industry:Natural environment
The openings or pore spaces in a rock, soil, and other such material.
Industry:Natural environment
The study of the factors that affect the growth, stability, and decline of populations, as well as the interactions of those factors.
Industry:Natural environment
A DNA vector that allows the insertion of long fragments of DNA (up to 50 kbases).
Industry:Natural environment
A linear transect where a chain is used to mark the line under study. By following the surface contour of the reef, chain transects provide data that may be used to calculate the estimated spatial index (the ratio of reef surface contour to linear distance of the reef).
Industry:Natural environment
A polygynous mating system where a number of males aggregate at a particular site during the breeding period and engage in courtship behavior, especially displays. Females attracted to the site "select " males for mating and subsequent fertilisation of eggs. Once mated, the females usually go elsewhere to lay their eggs or to complete gestation. Lekking behaviour (also called arena behavior) has been observed among cuttlefish, fishes, birds, antelope, and insects. Lekking species tend to stay at a single lek throughout a breeding season and to return to the same lek site from breeding period to breeding period.
Industry:Natural environment
A specialised parenchymous tissue in seagrass leaves that has regularly arranged air spaces or lacunae. These internal air spaces serve for flotation and exchange of gasses.
Industry:Natural environment
A type of speciation in which a founder or sink population is isolated from the parent or metapopulation, usually via colonisation of some new region.
Industry:Natural environment
An imaginary great circle on the surface of the Earth passing through the north and south poles at right angles to the equator; "all points on the same meridian have the same longitude".
Industry:Natural environment
As pertaining to coral reef ecosystems, a measure of the amount of coral surface area in relation to linear area. For example, branching coral reef habitats will have a higher structural complexity than encrusting coral reef habitats.
