Dead, unstable coral pieces often colonized with macroalgae. This habitat often occurs landward of well-developed reef formations in the reef crest or back reef zone.
Industry:Natural environment
In fishes, a spiny dorsal or anal fin ray.
Industry:Natural environment
Loci (or regions within DNA sequences) where short sequences of DNA nucleotides are repeated in tandem arrays (the sequences are repeated one right after the other). The lengths of sequences used most often are di-, tri-, or tetra-nucleotides. In the literature they can also be called simple sequence repeats (SSR), short tandem repeats (STR), or variable number tandem repeats (VNTR). Microsastellites are inherited in a Mendelian fashion. They are widely used in the following applications: forensic identification and relatedness testing; diagnosis and identification of diseases; population studies (by looking at the variation of microsatellites in populations, inferences can be made about population structures and differences, genetic drift, genetic bottlenecks and even the date of a last common ancestor); and conservation biology where they can be used to detect sudden changes in population, effects of population fragmentation, and interaction of different populations. Microsatellites are useful in identification of new and incipient populations.
Industry:Natural environment
The anterior, nonreproductive part of a marine polychaete worm, as distinct from the posterior, reproductive part (epitoke) during the reproductive season.
Industry:Natural environment
The internal organs, collectively, of an coelomate organism, especially those located within the abdominal cavity, but also to the organs within the thoracic and mediastinal cavities.
Industry:Natural environment
The relative occurrence of a gene in a given population, usually expressed as a percentage.
Industry:Natural environment
A condition that may occur in aquatic environments as the concentration of dissolved oxygen becomes reduced to a level harmful to aquatic organisms; in physiology, hypoxia is the condition where oxygen concentrations are below normal physiological limits in a specific tissue.
Industry:Natural environment
A group of organisms that has undergone significant genetic divergence from other groups of the same species. Identification of esus is based on natural history information, range and distribution data, and results from analyses of morphometrics, cytogene.
