A set of codes for representing alphanumeric information (e.g., a byte with a value of 77 represents a capital M). Text files, such as those created with the text editor of a computer system, are often referred to as ASCII files.
Industry:Natural environment
A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle.
Industry:Natural environment
A single-stranded nucleic acid found in the nucleus and cytoplasm of a cell. It is a polymer of the sugar ribose, phosphate, purine and pyrimidine bases. RNA is very similar to DNA, but substitutes the nucleotide, uracil, for thymine. It acts as a "middle-man", converting genetic information from DNA to proteins. There are three types of RNA: mrna (messenger RNA), which contains the specific sequence of nucleotides necessary to dictate amino acid sequence in proteins; trna (transfer RNA), which serves as the "adaptor" to position the appropriate amino acid next to a growing polypeptide chain during protein synthesis; and rrna (ribosomal RNA), which is the RNA component of ribosomes. In some viruses, RNA is the genetic material.
Industry:Natural environment
A small (35 km2) isolated and uninhabited island located at 18o25'n, 75o05'w, approximately 55 km west of the Tiburon Peninsula of Haiti and 220 km northeast of Jamaica. Navassa was designated as a United States National Wildlife Refuge in 1999. Corals and sponges grow on large underwater rocks that have broken off from the cliffs.
Industry:Natural environment
A small atoll lying at 18° 04' S, 163° 10' W on the western margin of the Cook Islands group in the South Pacific. This extremely isolated atoll hosts nesting green sea turtles in the spring and summer and humpback whales in the winter .
Industry:Natural environment
A small conspicuous constellation in the southern hemisphere in the Milky Way near Centaurus.
Industry:Natural environment
A small piece of glass or silicon that has small pieces of DNA arrayed on its surface.
Industry:Natural environment
A software program distributed by the National Coral Reef Institute that provides a tool for the estimation of benthic habitat cover using underwater images. The coverage can be estimated using the random point count method, and areas can also be traced, digitized, and calculated via image calibration. More information can be found at www.nova.edu/ocean/cpce.
Industry:Natural environment
A software program distributed by the National Coral Reef Institute that uses the Habitat Equivalency Analysis (HEA) method and provides an efficient means of calculating the amount of compensation required to provide services that are equivalent to the interim loss of natural resource services following injury. The program accepts input of parameters necessary to determine long-term service loss from the injury (injured area size and degree; times of injury, functional shape, and equilibrium; post-injury recovery); parameters to determine long-term service gain from compensatory restoration actions (times of restoration beginning and equilibrium; maximum service level; service gain function shape); and general program parameters (relative value of lost and gained services, baseline level of lost and gained services, discount rate). More information can be found at www.nova.edu/ocean/visual_hea .
Industry:Natural environment
A species identified as 'Extinct', 'Extinct in the wild', 'Critically endangered', 'Endangered', 'Vulnerable', 'Lower risk', 'Data deficient' or 'Not evaluated' according to criteria laid down in the IUCN Red List Categories (International Union for the C.
