Marine phytoplankton can be an important indicator for the changes in marine environments and ecosystems since they are major primary producers that consolidate solar energy into various organic matter transferred to marine ecosystems throughout the food-webs. Similarly, the N2 fixers (diazotrophs) are also vulnerable to changing environmental conditions. It has been found that the polar regions can be introduced to diazotrophic activity under warming conditions and the increased N availability can lead to elevated primary productivity. Considering the fundamental roles of phytoplankton in marine ecosystems and global biogeochemical cycles, it is important to understand phytoplankton ecology and N2 fixation as a potential N source in various oceans. This Special Issue provides ecological and biogeochemical baselines in a wide range of geographic study regions for the changes in marine environments and ecosystems driven by global climate changes.Research & information: generalbicsscEnvironmental economicsbicsscTEPTEP-Cphytoplanktonchlorophyll aPOCprimary productionJaran Bayparticulate organic matterbiochemical compositionChukchi SeaArctic OceanEast China SeaHPLCdiatomscyanobacteriaphytoplankton productivitycarbon and nitrogenstable isotopesKongsfjordenSvalbardbiochemical compositionscarbohydratesproteinslipidsScrippsiella trochoideaHeterosigma akashiwobiovolumechlorophyll-aparticulate organic nitrogenparticulate organic carbonSouth China SeaupwellingeddydiatomTrichodesmiumRhizosolenia-RicheliaProchlorococcusSynechococcusnorthwestern Pacific Oceanmacromolecular compositiontransparent exopolymer particlesRoss Seapolar nightmacromoleculesChukchi ShelfCanada Basinfood materialBering Seasmall phytoplanktonprimary productivityResearch & information: generalEnvironmental economicsLee Sang Heonedt884501Bhavya P.SedtKim Bo KyungedtLee Sang HeonothBhavya P.SothKim Bo KyungothBOOK9910585943603321Marine Nitrogen Fixation and Phytoplankton Ecology3031742UNINA
