In [[ecology]], '''local abundance''' is the relative representation of a species in a particular [[ecosystem]].{{Cite journal|last=Preston|first=F.W.|date=July 1948|title=The Commonness, and Rarity, of Species|url=http://www.bgu.ac.il/desert_agriculture/Vegecology/Papers/Preston48.pdf|journal=Ecology|volume=29|issue=3|pages=254–283|via=Ben-Gurion University of the Negev|doi=10.2307/1930989|jstor=1930989|bibcode=1948Ecol...29..254P |access-date=2019-02-12|archive-date=2014-12-22|archive-url=https://web.archive.org/web/20141222030534/http://www.bgu.ac.il/desert_agriculture/Vegecology/Papers/Preston48.pdf|url-status=dead}} It is usually measured as the number of individuals found per [[Sample (statistics)|sample]]. The ratio of abundance of one species to one or multiple other species living in an ecosystem is referred to as [[relative species abundance]]s. Both indicators are relevant for [[measurement of biodiversity|computing biodiversity]]. |
