The unified neutral theory of biodiversity and biogeography (here "Unified Theory" or "UNTB") is a hypothesis and the title of a monograph by ecologist Stephen Hubbell. The hypothesis aims to explain the diversity and relative abundance of species in ecological communities, although like other neutral theories of ecology, Hubbell's hypothesis assumes that the differences between members of an ecological community of trophically similar species are "neutral", or irrelevant to their success. This implies that biodiversity arises at random, as each species follows a random walk. The hypothesis has sparked controversy, and some authors consider it a more complex version of other null models that fit the data better.

  • 中立理論(ちゅうりつりろん)とは、生物地理学や生態学における理論の一つである。 一つのにおける生物の種多様性を取り扱うための一般理論として構想されたもので、生態群集の構造化が物理的要因や生物相互作用だけでなく個体群統計学的確率性によっても成立するという仮説に基づいている。生物多様性の中立説ともいう。
