The new (4th) edition of "Wetzel's #Limnology: #Lake & #River #Ecosystems" is now published! It was an honor to contribute to this multi-year project & work with Tonya DelSontro on the "Organic #Carbon Cycling & Ecosystem #Metabolism" chapter (there was A LOT to try to fit into the updated text thanks to so much great work on this topic since 2001!).
