Sediment and water nutrients and microalgae in a coastal shallow lagoon, Ria Fo...
Brito, Ana; Newton, Alice; Tett, Paul; Fernandes, TeresaCoastal shallow lagoons are considered to be highly important systems, which have specific biogeochemical cycles and characteristics. The assessment of sediment–water interfaces is essential to understand nutrient dynamics and to evaluate the vulnerability to eutrophication, especially in regions of restricted water exchange (RRE), such as the Ria Formosa, which have natural conditions for the accumulation of n...
Development of an optimal methodology for the extraction of microphytobenthic c...
Brito, Ana; Newton, Alice; Tett, Paul; Fernandes, TeresaBenthic microalgae are important primary producers in intertidal shallow systems. Their biomass can be estimated by the assessment of chlorophyll a concentration. A rapid and reliable method of measuring chlorophyll a is by spectrophotometer. There is however, no standard protocol for the analysis of benthic chlorophyll a. Although the most common solvent generally used is 90% acetone, some authors showed bette...
