Those efforts to guide economic growth in an environmentally sound manner with an emphasis on natural resource conservation.
Industry:Natural environment
Structures designed to mimic the complex coral reef environment and attract colonizing coral reef organisms in order to assess invertebrate biodiversity by measuring/monitoring diversity of cryptic organisms globally over time. ARMS provide standard methods for taxonomic and molecular analyses to assess invertebrate biodiversity. Information from the ARMS will provide managers with a tool to assess this diversity along with the affects of climate change and ocean acidification, globally. More than 500 ARMS have been deployed throughout the Pacific, Indian, and Atlantic Oceans.
Industry:Natural environment
A collection of clones made from a set of randomly generated overlapping DNA fragments that represent the entire genome of an organism.
Industry:Natural environment
A general name for several species of halophyte belonging to different families of plants (including trees, shrubs, a palm tree and a ground fern) occurring in intertidal zones of tropical and subtropical sheltered coastlines and exceeding one half meter in height. The term is applied to both the individual and the ecosystem, the latter of which is termed mangal. Mangroves provide protected nursery areas for juvenile reef fishes, crustaceans, and mollusks. They also provide a feeding ground for a multitude of marine species. Many organisms find shelter either in the roots or branches of mangroves. Mangrove branches are nesting areas for several species of coastal birds. The root systems harbor organisms that trap and cycle nutrients, organic materials and other important chemicals. Mangroves also contribute to higher water quality by stabilizing bottom sediments, filtering water and protecting shorelines from erosion. They protect reefs from land runoff sedimentation. Conversely, coral reefs protect mangroves and seagrasses from erosion during heavy storms and strong wave action. The nations with the largest mangrove areas include Indonesia (with 21% of global mangroves), Brazil (9%), Australia (7%), Mexico (5%), and Nigeria (5%).The global area of mangroves – 150 000 square kilometers – is equivalent to the area of the state of Illinois, or half the area of the Philippines. About one fifth of all mangroves are thought to have been lost since 1980, and although loss rates are declining, they are still 3 to 4 times higher than average global forest loss estimates.
Industry:Natural environment
A microscope that has a special condenser and objective with a diaphragm that scatters light from the observed object. The object appears bright on a dark background.
Industry:Natural environment
A resemblance to vegetation which allows organisms to conceal themselves from predators or prey.
Industry:Natural environment
A survey which creates, marks, defines, retraces or reestablishes the boundaries and subdivisions of the public land of the United States. It is derived from the word cadastre, meaning a public record, survey, or map of the value, extent, and ownership of land as a basis of taxation.
Industry:Natural environment
An organism that releases gametes directly into the sea for external fertilization.
Industry:Natural environment
Common name for species of the anthozoan order Alcyonacea of the subclass Octocorallia. In contrast to the hard or stony corals, most soft corals do not possess a massive external skeleton.
