Item Description: Many lakes world-wide are increasingly impacted by eutrophication and deoxygenation. This paper, combining empirical data and modelling, shows that diurnal migrating Chaoborus, which is highly abundant in eutrophic lakes with hypoxic bottom water, can sustain oxygen deficiency and nutrient internal loading in lakes. This "Chaoborus pump" effectively counteract lake management and remediation efforts that rely on curbing external nutrient input and artificial aeration. The results of the study call for a new strategy in lake remediation.
