Resistance strategies of Phragmites australis (common reed) to Pb pollution in flood and drought conditions.

abstract：:'Living fossils', a phrase first coined by Darwin, are defined as species with limited recent diversification and high morphological stasis over long periods of evolutionary time. Morphological stasis, however, can potentially lead to diversification rates being underestimated. Notostraca, or tadpole shrimps, is an an...
