found: Oxford evol. biol. WWW site, Sept. 26, 2007(Allee effect: W.C. Allee brought attention to the possibility of a positive relationship between aspects of fitness and population. This phenomenon, frequently termed the Allee effect has been the focus of increased interest ... in the light of concerns over conservation and the problems of rarity. Use of the term suffers from the absence of a clear definition however, with the result that Allee effects are frequently thought to involve only a narrow range of phenomena and are often overlooked altogether)
