The Convention on International Trade in Endangered Species of Wild Fauna and Flora was negotiated in 1973 and originally signed by 85 countries. Mauritania became a party to CITES in June, 1998, bring the total number of participating countries to 144. It is designed to promote conservation of endangered species while allowing commerce in species of wildlife that can withstand the pressures of trade. The convention has three categories of protection. Under its Appendix I, commercial trade in species that are threatened with extinction is generally prohibited. These species may be traded only under special conditions (usually for scientific research or display purposes). Such transactions require both an import permit from CITES authorities in the recipient country and an export permit from authorities in the country of origin... CITES allows conditional commercial trade in species that are not yet endangered but merit monitoring. These species are listed on Appendix II and may be traded only with an export permit from their country of origin. A third appendix to CITES is intended to help individual countries gain international cooperation in protecting native species. Any country may place a native plant or animal on Appendix III, making the species conditionally tradable. The species may not be traded without either an export permit from its native country (if that country listed it on Appendix III) or a certificate of origin (if it comes from a country that did not list it).

A lowland plains area in Bolivia and Paraguay containing soils carried down from the Andes. It is characterized by dry deciduous forest and scrub, transitional between rain forest
Found in coastal areas between 30 and 40 degrees latitude, in areas with a Mediterranean climate. Vegetation is dominated by stands of dense, spiny shrubs with tough (hard or waxy) evergreen leaves. May be maintained by periodic fire. In South America it includes the scrub ecotone between forest and paramo.

a receptor that detects the presence of chemicals and, in multicellular organisms, transmits this information to the nervous system.
referring to the sensation of chemical signals. The portion of the nervous system devoted to detecting and interpreting chemical signals.
a polysaccharide comprised of derivatives of glucose. It is structurally similar to cellulose and is used to harden or strengthen structures in various invertebrates, such as the cuticle of arthropods, and in fungi.
cells which line the flagellated canals and chambers of sponges, Phylum Porifera. The exposed end of a choanocyte cell bears a flagellum surrounded by a collar that filters food particles from the water.
to jointly display, usually with sounds, at the same time as two or more other individuals of the same or different species
pigment-containing cells found in the skin of many vertebrates, crustaceans, and molluscs. Pigment granules concentrate or disperse in the cytoplasm of the cell, causing the animal to better match its surroundings.
singular: cilium. Short, minute, hair-like projections (up to 10 micrometers long) present on the surface of many cells, especially protozoans and vertebrate epithelium. The movement of cilia can cause cell movement or cause liquids to pass over the cell surface.

used loosely to describe any group of organisms living together or in close proximity to each other - for example nesting shorebirds that live in large colonies.
