'''Extinction threshold''' is a term used in [[conservation biology]] to explain the point at which a [[species]], [[population]] or [[metapopulation]], experiences an abrupt change in density or number because of an important parameter, such as habitat loss. It is at this critical value below which a species, population, or metapopulation, will go [[extinct]],Ovaskainen, O. and Hanski, I. 2003:Extinction Threshold in Metapopulation Models, Ann.Zool.Fennic.40:81-97. though this may take a long time for species just below the critical value, a phenomenon known as [[extinction debt]].{{Cite journal | last1 = Tilman | first1 = D. | last2 = May | first2 = R.

Extinction thresholds are important to conservation biologists when studying a species in a population or metapopulation context because the colonization rate must be larger than the extinction rate, otherwise the entire entity will go extinct once it reaches the threshold.Groom, M., Meffe, G. K., and Carroll, C.R. 2000:Principles of Conservation Biology, 3rd Ed, Sinauer Associates. |
