The importance of extracellular carbohydrate productionby marine epipelic diatoms
Abstract Soft-sediment habitats in intertidal and shallow subtidal marine ecosystems frequently support extensive populations of benthic microalgae (microphytobenthos). These algal assemblages areExpand

The measurement of microbial carbohydrate exopolymers from intertidal sediments
Measurements of microbial extracellular polymeric substances (EPS) of natural field populations are required to understand the processes of biogenic stabilization and the microbial ecology ofExpand

THE UPS AND DOWNS OF LIFE IN A BENTHIC BIOFILM: MIGRATION OF BENTHIC DIATOMS
Benthic diatom communities have been documented many times to exhibit a predictable pattern of migration entrained to diurnal and tidal cycles forming transient biofilms in the estuarine intertidal.Expand

ENVIRONMENTAL EFFECTS ON EXOPOLYMER PRODUCTION BY MARINE BENTHIC DIATOMS: DYNAMICS, CHANGES IN COMPOSITION, AND PATHWAYS OF PRODUCTION 1
Marine benthic diatoms excrete large quantities of extracellular polymeric substances (EPS), both as a function of their motility system and as a response to environmental conditions. Diatom EPSExpand

Responses of microphytobenthos to light: primary production and carbohydrate allocation over an emersion period
The effect of high (ambient) and low (shaded to 50 % of ambient) light on microphytobenthic biofilm primary production, vertical migration and allocation of photoassimilated carbon into extracellularExpand

PAM FLUORESCENCE: A BEGINNERS GUIDE FOR BENTHIC DIATOMISTS
Chlorophyll a fluorescence techniques have increasingly been applied in and ex situ for the study of microphytobenthic ecology and photophysiology. Fluorescence measurements have gained popularity,Expand

Significance of diatom-derived polymers in carbon flow dynamics within estuarine biofilms determined through isotopic enrichment
Pennate diatoms are the main group of primary producers in transient microbial biofilms at the sediment surface in muddy intertidal systems. These microalgae produce a substantial quan- tity ofExpand

Diatom-Derived Carbohydrates as Factors Affecting Bacterial Community Composition in Estuarine Sediments
ABSTRACT Microphytobenthic biofilms in estuaries, dominated by epipelic diatoms, are sites of high primary productivity. These diatoms exude large quantities of extracellular polymeric substancesExpand

Adaptations of tropical marine microphytobenthic assemblages along a gradient of light and nutrient availability in Suva Lagoon, Fiji
How are microphytobenthic biofilms adapted to the high incident irradiances and temperatures, low inorganic nutrient concentrations and high desiccation stresses on intertidal flats present inExpand
