Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
Common names of animal species are written either in title case or sentence case depending upon the taxonomic group (shown below). In title case, the first letter of every important word is capitalized (e.g., Grey Currawong, Duke of Burgundy), except for words that follow a hyphen (e.g., Brown-headed Spider Monkey).
An example is the genus Pomatia Beck, 1837, [9] which was established for a group of terrestrial snails containing as its type species the Burgundy or Roman snail Helix pomatia—since Helix pomatia was already the type species for the genus Helix Linnaeus, 1758, the genus Pomatia was an objective synonym (and useless).
The following is a list of tautonyms: zoological names of species consisting of two identical words (the generic name and the specific name have the same spelling). Such names are allowed in zoology, but not in botany, where the two parts of the name of a species must differ (though differences as small as one letter are permitted, as in cumin, Cuminum cyminum).
Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
The hierarchy of scientific classification. Taxonomy mnemonics are used to memorize the scientific classification applied in taxonomy. They are usually constructed with a series of words that begin with the letters KPCOFGS, corresponding to the initials of the primary taxonomic ranks.
Epithets from proper nouns, proper adjectives, and two or more nouns are excluded, along with epithets used only in species names that are no longer widely accepted. Classical and modern meanings are provided in the third column, along with citations to Charlton T. Lewis 's An Elementary Latin Dictionary .
