A a-phorbins as indicators of the changes in total lake productivity. The individual phorbins are indicated in different colors corresponding to chlorophyll-a (Chla), pheophytin-a (Pheoa), pheophorbide-a (Phora), and chlorophyllide-a (Chlpa). B The alloxanthin/a-phorbin ratio indicates the contribution of cryptophytes, an exclusively planktonic group, to lake productivity. C Diatoxanthin/a-phorbin ratio indicates the diatoms’ contribution to lake productivity. D Lutein/a-phorbin ratio indicates the chlorophytes’ contribution to lake productivity. Source data can be found in Supplementary Data 2.
