— This glossary was compiled and edited by volunteer scientists from multiple scientific disciplines using reputable sources, including the references listed at the bottom of this page. If you don’t find the scientific word, term, or expression you are looking for, let us know in the comment section below, and we will research the word for you, and add it to the glossary. We desperately need editors to flesh this glossary out. If you are interested, please contact email@example.com:
- nearctic: Gr. νεα “nea” = young, youthful, new, fresh + Gr. αρκτικος “arctikos” = arctic, northern: 1. biogeography — temperate and arctic parts of North America, including Greenland; one of eight terrestrial ecosystems into which the globe is subdivided.
- nematode: Gr. νημα “nema” = thread; 1. Zoology: nematodes, also known as roundworms, comprise the phylum Nematoda; they are the most diverse phylum within the unofficial grouping known as pseudocoelomates. Nematodes lack vascular blood systems (nutrients and wastes circulate in the body by diffusion and osmosis); have no skeletons (depending instead on hydrostatic pressure to support the body); are not segmented; have a body wall of epidermis and muscle fibers, usually covered by a secreted cuticle; are generally microscopic; and are parasites and parasitoids of almost every form of life, though some are free-living. Over 28,000 species have been described, over 16,000 of them parasitic. It is widely believed over 1,000,000 nematode species exist.
- neotropic: Gr. νεος “neos” = young, youthful, new fresh + Gr. τροπικος “tropicos” = of the tropics; 1. biogeog. — tropical North, Central, and South America, including southern Florida, the Mexican lowlands.
- nomen dubium (pl. nomina dubia): L. nomen = a name + dubius = doubtful, wavering in opinion; 1. taxon. — scientific names of doubtful or unknown application.
- nomen nudem (pl. nomina nuda): L. nomen = a name + L. nudas = naked, nude; 1. taxon. — scientific names that could not, at the time the label was applied, be associated with a recognizable biological entity.
anat. = anatomy; arach. = arachnid; behav. = behavioral; biol. = biological (inclusive of all animals and plants); bot. = botanical (inclusive of all plants); Gr. = Greek; L. = Latin; q.v. = L. quod vide = which see; pl. = plural; taxon. = taxonomy; zool. = zoological (inclusive of all animals).
