“…This estuarine turbidity maximum (ETM) is formed by high concentration of suspended particulate matter, that is governed by the tidal resuspension and advection of fine-grained particles, attributed to complex couplings between circulation, tidal asymmetries and stratification [27][28][29]. Several studies have observed ETM in the Seine estuary [30,31]. Fig.…”

“…Microbial activity on detritus can release nutrients to the water column (Biddanda 1988). Seasonal and daily hydrologic conditions, such as tide, temperature, irradiance, wind and currents, can greatly influence the concentration and composition of living and nonliving suspended POM (Bodineau et al 1998(Bodineau et al , 1999Sakdullah and Tsuchiya 2008;Wyatt et al 2010). For example, tidal mixing can resuspend sediment, increasing nutrient concentrations for pelagic phytoplankton and adjacent benthic habitats; however, nutrient availability must also coincide with sufficient irradiance for photosynthetic organisms (Sakdullah and Tsuchiya 2008;Schaal et al 2008).…”

Surface water samples of size-selected seston (0.7-20 lm) were collected from April 2013 to September 2013 at three similar coarse-sand benthic habitats. Additionally, seston sampling was performed at a fixed location throughout a complete tidal cycle (2014). A combination of fatty acid (FA), isotope, and flow cytometry analyses were used to determine the quality and quantity of nano-and pico-sized particulate organic matter (POM). High variability was found between fatty acid replicate samples. Similar temporal patterns were observed at two sheltered sites, while the exposed site displayed less pronounced seasonal changes. Lower concentrations of 16C and 18C polyunsaturated fatty acids were found during low tide sampling. Globally, POM was dominated by picoeukaryotes, with concentrations exceeding 50,000 cells mL 21 , and (16:4x3 1 18:3x3)/Rx3 is proposed as novel biomarker of picoeukaryotes in this region.

“…As in nearby coastal areas [42], seston levels at Quempillén are largely determined by phytoplankton dynamics rather than sediment resuspension [7]. Similar patterns of variation (tidal superimposed on seasonal) in seston have also been recorded in coastal habitats, including estuaries, in other latitudes [2,44,39].…”

The influence of season and the tidal cycle on division of labour by the radula during feeding in the estuarine brooding gastropod Crepipatella dilatata (Calyptraeidae)

The brooding gastropod Crepipatella dilatata can feed by scraping the substrate with the radula and by suspensionfeeding, which also requires use of the radula. There is a "division of labour" for the radula among three discrete tasks associated with feeding: (1) removing mucous balls from the food pouch; (2) transferring the mucous cord from the neck channel to the mouth (both components of suspension-feeding); (3) scraping the substrate. We hypothesised that the proportion of time used for each feeding activity varies according to environmental conditions. Total radular activity in females was greatest at high tide and in summer. The rate of radular extrusion for ingesting the mucous cord varied seasonally and between brooding and non-brooding females. Non-brooding females exhibited higher rates of radular extrusion for ingesting the mucous cord and for scraping the substrate than did brooders. In females, radular activity in removing the mucous ball from the food pouch was strongly influenced by the tidal cycle during winter, reaching minimum values at low tide. Differences were recorded in substrate scraping among seasons and within tidal cycles, and among males, brooding females and non-brooding females. Brooding females displayed less rasping than non-brooders, since the area available for grazing was restricted by the egg mass. Throughout the year, including low salinity periods, males allocated a greater proportion of total radular activity to rasping than to removing the mucous ball or ingesting the mucous cord. The feeding behaviour of both males and females is modulated by salinity, but the principal determinants of radular activity are the mode of reproduction (brooding in females) and, in males, motility.
