Planktonic food webs revisited: Reanalysis of results from the linear inverse approach By linking diversity, structure and function in the plankton food-web, we discuss the role of internal mechanisms, relying on species-specific functionalities, in driving the Гўв‚¬ЛњadaptiveГўв‚¬в„ў responses of plankton communities to perturbations. For instance, from green to blue states, a seven-fold decrease in phytoplankton biomass translated into only a two-fold decrease in potential planktivorous fish biomass. Switches in food-web structure resulted in relatively small differences in the efficiency of material transfer towards higher trophic levels. Such re-organization stemmed from switches in selective grazing by both metazoan and protozoan consumers. The green and blue food-webs showed distinct organizations in terms of trophic roles of the nodes and carbon fluxes between them. Taxonomically disaggregated food-webs described herein allowed to shed light on how components of the plankton community changed their trophic behavior in the two different conditions, and modified the overall functioning of the plankton food web. The model was implemented in two variants - which we named Гўв‚¬ЛњgreenГўв‚¬в„ў and Гўв‚¬ЛњblueГўв‚¬в„ў - characterized by opposite amounts of phytoplankton biomass and representing, respectively, bloom and non-bloom states of the system.
