Reefbase is a global online information system (www.reefbase.org) on coral reefs. It provides information services to coral reef professionals involved in management, research, monitoring, conservation and education. Reefbase's online geographic information system (GIS) allows the display of coral reef related data and information on interactive maps. One can zoom in to a particular area of interest, switch various data layers on and off, and save or bookmark the map for later viewing, printing or use in presentations/documents.
Industry:Natural environment
A class of stable organic molecules made up of only carbon and hydrogen. These molecules are highly carcinogenic, but also very common in the enviropnment. Pahs are formed during the incomplete burning of coal, oil and gas, garbage, and other organic substances, such as tobacco or even charcoal broiled meat. Pahs enter water through discharges from industrial and wastewater treatment plants or through the release of boat engine exhausts. Ultraviolet light (UV) transforms the pahs into toxic forms that kill crustaceans, polychaetes, and coral larvae.
Industry:Natural environment
A gelatinous material secreted by specialized mucous cells. In corals, it functions in protection from bacterial invasion, food capture, and removal of sediment particles. Mucus is usually moved by cilia (motile hair-like extensions of the cell membrane).
Industry:Natural environment
A method for deepening streams, swamps or coastal waters by scraping and removing solids from the bottom. The resulting mud is usually deposited in marshes in a process called filling. Dredging and filling can disturb natural ecological cycles. For example, dredging can destroy coral reefs and other aquatic life; filling can destroy the feeding and breeding grounds for many fish and invertebrate species.
Industry:Natural environment
A regional, quasi-governmental group with authority to manage fisheries in federal waters, generally from three to 200 miles offshore.
Industry:Natural environment
A substance that takes part in the process of metabolism, which involves the breakdown of complex organic constituents of the organism's body with the liberation of energy for use in bodily functioning. The various compounds that take part in, or are formed by, these reactions are called metabolites.
Industry:Natural environment
All the interactions of predator and prey, included along with the exchange of nutrients into and out of the ecosystem. These interactions connect the various members of an ecosystem, and describe how energy is converted and passes from one organism to another.
Industry:Natural environment
Closely-related species that are nearly morphologically indistinguishable.
