Climate change is considered to be one of the most severe threats to earth and aquatic ecosystems and the concern about the effects that global warming can have on biological communities is increasing. Even if the number of studies concerning climate change is increasing the effects of climate change are challenging to monitor and understand because of the multitude of responses within an ecosystem. In the last years, analyses of long-term data sets provide increasing evidence on the sensitivity of water bodies to climatic fluctuation. Moreover, small size and fast reproducing zooplankton organisms are key components of aquatic food webs and they are particularly sensitive to environmental change. The main aim of this study is to achieve generalized information on how climate variation can affect zooplankton population dynamics in relation to different lakes trophic evolution and how this affects the entire lake ecosystems. We combined the analysis of long term limnological dataset to paleolimnological studies to disentangle the effects of climate change and other anthropic pressure (i.e. eutrophication). Our results suggest that in deep lakes winter climatic variability trigger a cascading effect that involves the entire lake ecosystems, modifying lake chemical, physical and biological characteristic. Climate change can mimic or reinforce the effect of eutrophication process, promoting algal development and increasing the phosphorus accumulation in the hypolimnion. The impact of global warming on zooplankton population dynamics indirectly affect the entire lake food webs and interfere with some lakes management strategies
