About this book

This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organisation from bacteria to fish. Special emphasis is paid to carbon cycling and food web organisation in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.
