Webthe hypothesis that "diversity begets stability" and, from the early 1970's, much theoretical and experimen-tal work has probed the tangled web of biodiversity-stability-productivity relationships, in terrestrial eco-systems in particular. What is new is that the questions have become more specific. Specific ecosystem functions WebThis theory agrees with recent experiments and provides a degree of resolution to the diversity-stability debate: both sides of the longstanding debate were correct, but one addressed population stability and the other addressed community stability.
