OpenNESS Glossary beginning with T


Taxon (Pl. Taxa) search for term

The named classification unit to which individuals or sets of species are assigned. Higher taxa are those above the species level. For example, the common mouse, Mus musculus, belongs to the Genus Mus, the Family Muridae, and the Class Mammalia.

Threatened Species search for term

Species that face a high (vulnerable species), very high (endangered species), or extremely high (critically endangered species) risk of extinction in the wild.

Threshold search for term

(Ecological) A point at which an ecological system experiences a qualitative change, mostly in an abrupt and discontinuous way. In the context of OpenNESS we use ecological threshold and tipping points as synonyms. See also ‘regime shift’ and the distinction with ‘limit’.

Tipping Point search for term

Used here as being synonymous with 'ecological threshold'.
