Arctic Biodiversity Assessment (ABA) 2013. Figure 13.6. Occurrence and pigmentation of water fleas Daphnia sp. in ponds with different dissolved organic carbon (DOC) concentrations. White bars indicate the number of ponds where waterfleas are absent and the black bar the number of ponds with waterfleas. DOC of 5 mg per liter defi nes the transition from oligotrophic to mesotrophic waters. The box plot shows the concentration of melanin pigment (related to carbon biomass) in water fleas. Data from Rautio & Korhola (2002).
