摘要: Crustacean remains are not yet useful as parameters for assessing the recent acidification phenomenon, due to too few studies on their ecology. The changes observed in sediments related just lake chemistry, but also predatory and competitive interactions. Moreover, habitat pH of organism may differ from measured pH, such be representative. Therefore, species some acidic lakes decrease abundance, whereas same nearby increase. caution mainly concerns with no clear distribution. Species predominant or alkaline generally follow patterns more closely physiology. Study pelagic species, including both body size shape measurements, should included analysis. If all ecological factors included, animal well algal would form powerful tools reveal histories.
