  abstract = {{C}oastal marshes are submitted to huge management due to anthropogenic pressure and thus, it is essential to preserve their biodiversity, their ecological functions and the ecosystem services they can provide. {T}his study investigates the diversity and abundance of planktonic communities (heterotrophic prokaryotes, heterotrophic protists, microphytoplankton and metazooplankton). {T}he aim of this study is to provide a first quantitative in-ventory on the plankton communities present in two marshes and to construct the different typologies of planktonic food webs in these marshes. {S}easonal samplings (4) for environmental variables, nutrient concen-trations and planktonic communities were conducted at 2-3 stations on each marsh during a year. {A} total of five different types of planktonic food web were determined, three of them were found in both marshes. {T}he salt -marsh phytoplanktonic communities were dominated by {C}ryptophyta, nanoflagellates and {C}yanobacteria. {T}he freshwater marsh was dominated by {C}ryptophyta in autumn and winter and by a diverse phytoplankton com-munity in spring. {M}arine copepods ({C}alanoida and {H}arpacticoida) characterized the saltwater metazooplank-tonic communities, {C}ladocerans and {R}otifera the freshwater ones. {O}verall, the planktonic diversity was higher in the freshwater marsh (102 taxa) than in the saltwater marsh (54 taxa). {P}hytoplankton blooms represented nutrient and {CO}2 uptake in both marshes and this purification function seemed most efficient in autumn in the saltmarsh. {C}onsiderable zooplankton communities represented a po-tential for nursery. {O}f the three management actions performed, only periodic water renewals might affect the seasonal dynamics of planktonic communities.},
