Climate change is altering the status of lake ecosystems, not only through steady water warming but also with increasing frequency, duration and intensity of droughts and heatwaves. These extreme events, especially if concurrent, have relevant effects on moderately deep lakes, triggering severe stratification periods that lead to acute bottom anoxia. Such conditions notably trigger the release of phosphorus from sediments. Mor...

Eutrophication is still a serious issue for many lakes in the subalpine lake district of Northern Italy. Significant improvements have been achieved thanks to interventions carried out on their watersheds, whereas the Water Framework Directive of the European Union (EU WFD) has established ecological and chemical water quality targets. Unfortunately, climate change and remaining pollution inputs by human activities play a syne...
