| Abstract | : | Since most physiological, ecological, or physical processes in marine ecosystems are size-dependent, plankton size spectra are important indicators of the efficiency of the biological carbon pump and other plankton-mediated fluxes. Global predictions of plankton size spectra have recently started to integrate direct size measurements provided by imaging sensors, albeit they currently do not resolve plankton diversity within their size distributions. Using imaging datasets recently compiled as part of the Pelagic Size Structure database initiative (https://pssdb.net/), we investigate the size distribution of numerically important taxa at the global scale. More specifically, we assessed the size spectra of Rhizarians, Crustaceans and colonial N2 fixers and explored their relationships with environmental factors. We found strong linkages between temperature and the size structure of all the groups, but individual responses to iron acquisition or mesoscale circulation helped distinguish specific niches within the plankton community. We used these responses to predict the biogeography of different plankton groups, each showing good agreement with independent observations. Such analysis should help constrain the stocks (i.e. integral of the size spectrum) and the roles of these significant actors of marine biogeochemical cycles with respect to various ecological and biogeochemical processes. |
