Key Features of Intertidal Food Webs That Support Migratory Shorebirds
The migratory shorebirds of the East Atlantic flyway land in huge numbers during a migratory stopover or wintering on the French Atlantic coast. The Brouage bare mudflat (Marennes-Oléron Bay, NE Atlantic) is one of the major stopover sites in France. The particular structure and function of a food web affects the efficiency of carbon transfer. The structure and functioning of the Brouage food w...
متن کاملDetermination of heavy metal (Cr, Zn, Cd and Pb) concentrations in water, sediment and benthos of the Gorgan Bay (Golestan province, Iran)
The coastal area of the Caspian Sea and Gorgan Bay are important ecosystems receiving discharge from their tributaries. In this study, concentration of lead (Pb), cadmium (Cd), zinc (Zn) and chromium (Cr) was seasonally determined at 8 sampling points during 2009-2010. Water samples were collected from the sampling stations and transferred to laboratory in polyethylene containers, whereas, sedi...

متن کاملViral Impact on Prokaryotic and Microalgal Activities in the Microphytobenthic Biofilm of an Intertidal Mudflat (French Atlantic Coast)
This is the first report on viriobenthos activity within the microbial biofilm located at the top-surface of the intertidal mudflat during emersion in Marennes-Oléron Bay (France). By combining in situ and ex situ approaches, the viral production (VP) was linked to the dynamics of prokaryotes and microphytobenthos (MPB). VP averaged 2-4 × 10(8) viruses ml(-1) h(-1). VP correlated positively wit...
متن کاملBiochemical composition and changes of extracellular polysaccharides 1 ( ECPS ) produced during microphytobenthic biofilm development
12 The main goal of this work was to study the dynamics and biochemical composition of 13 ExtraCellular Polysaccharides (ECPS), a fraction of the Extracellular Polymeric Substances 14 (EPS) produced during the development of a microphytobenthic biofilm in a European 15 intertidal mudflat (Marennes-Oléron Bay, France) during winter. Microphytobenthic biomass 16 was surveyed during four consecuti...
