“…This also suggests that flow current velocity is a major driver. The increased contribution of microphytobenthos to Z. noltei sediments with decreasing flow velocities and the higher contribution of microphytobenthos to the higher intertidal S. marina sediments, where flow velocities are lower, are probably related to lower re-suspension, a pattern that has been well described in tidal flats 53 . Important contributions of microphytobenthos and POM to sedimentary OC were also described elsewhere for seagrass meadows 54,55 .…”

Coastal vegetated ecosystems are major organic carbon (OC) and total nitrogen (TN) sinks, but the mechanisms that regulate their spatial variability need to be better understood. Here we assessed how superficial sedimentary OC and TN within intertidal vegetated assemblages (saltmarsh and seagrass) vary along a flow gradient, which is a major driver of sediment grain size, and thus of organic matter (OM) content. A significant relationship between flow current velocity and OC and TN stocks in the seagrass was found, but not in the saltmarsh. OC and TN stocks of the saltmarsh were larger than the seagrass, even though that habitat experiences shorter hydroperiods. Mixing models revealed that OM sources also varied along the flow gradient within the seagrass, but not in the saltmarsh, showing increasing contributions of microphytobenthos (17–32%) and decreasing contributions of POM (45–35%). As well, OM sources varied vertically as microphytobenthos contribution was highest at the higher intertidal saltmarsh (48%), but not POM (39%). Macroalgae, seagrass and saltmarsh showed low contributions. Local trade-offs between flow current velocities, hydroperiod and structural complexity of vegetation must be considered, at both horizontal and vertical (elevation) spatial dimensions, for better estimates of blue carbon and nitrogen in coastal ecosystems.

“…Many studies have investigated aquatic microorganisms inhabiting high-saline environments; yet, numerous questions remain on ecology of benthic diatoms. Diatoms are crucial primary producers and important food sources for many aquatic lives in marine environments (Park et al 2014). They are also one of the most diverse groups of extremophiles, being documented in almost every aquatic environment.…”

“…Some of the main factors influencing MPB biomass seasonality are light, nutrients, physical disturbance and grazing (Van Colen et al 2014, Savelli et al 2018. Contrastingly, studies on the taxonomic structure of the diatomdominated MPB communities have become scarcer (Park et al 2014), particularly those covering spatial and temporal patterns of both MPB biomass and MPB assemblage structure (Ribeiro 2010). Intertidal diatom assemblage composition varies both seasonally and spatially, not only within estuaries but also between estuaries (Underwood & Barnett 2006).…”

Diatom-dominated microphytobenthos (MPB) communities of 4 intertidal mudflats along the meso- and polyhaline reaches of the Loire Estuary, France, were investigated during a year cycle. They were analysed in terms of biomass, diversity, species composition and growth form distribution. The assemblages of the 2 upstream sites were characterised by high biomass and lower diversities and were mostly dominated by epipelon. The 2 downstream, most haline sites had lower biomass and higher diversities and were dominated by both epipelon and tychoplankton. Diversity did not exhibit a clear seasonal signal in the upstream mudflats, but it was higher during the first half of the study in the downstream sites. The coexistence of 2 growth forms seems to increase diversity of the mudflat assemblages. Species distribution was mainly linked to changes in sediment texture and salinity, both with a marked seasonal variability. MPB biomass was inversely related to MPB diversity and positively related to both mud content and the epipelon. MPB diversity was not, however, significantly correlated with mud content. Slight changes in sediment texture, even if causing variations in assemblage composition, did not change overall diversity. The existence of an important and even dominant tychoplanktonic fraction could be considered a distinctive feature of these benthic environments in the Loire, as well as in other macrotidal estuaries.
