Functionally reversible impacts of disturbances on lake food webs linked to spatial and seasonal dependencies
Abstract Increasing human impact on the environment is causing drastic changes in disturbance regimes and how they prevail over time. Of increasing relevance is to further our understanding on biological responses to pulse disturbances (short duration) and how they interact with other ongoing press...
