Microbes Dictate Regime Shifts Causing Anoxia In Lakes And Seas

Gradual environmental changes due to eutrophication and global warming can cause a rapid depletion of oxygen levels in lakes and coastal waters. A new study led by professors Jef Huisman and Gerard Muyzer of the University of Amsterdam (UvA) shows that microorganisms play a key role in these disastrous regime shifts. The researchers' findings were published in the journal Nature Communications on 6 October. Regime shifts are abrupt, large and persistent changes in the structure and function of ecosystems triggered by gradual changes in environmental conditions. Regime shifts have been described for a large variety of ecosystems.
