It is well documented that the combination of low nitrogen and phosphorus resources can lead to situations where colimitation of phytoplankton growth arises, yet the underlying mechanisms are not fully understood. Here, we propose a Droop-based model built on the idea that colimitation by nitrogen and phosphorus arises from the uptake of nitrogen. Indeed, since N-porters are active systems, the...

Coastal and estuarine food webs receive large inputs of both autochthonous allochthonous detritus, which serves as an important dietary input for a variety detritivorous omnivorous organisms. Surfactants, aid digestion by solubilizing hydrophobic lipids, are found in the gut-fluids many fish invertebrate consumers. To develop biomimetic assay to explore how source primary production age may aff...

In recent years, the use of photosynthetic microorganisms, such as microalgae, in life sciences has received increasing attentions due to their diverse phytometabolic contents with various chemical structures and biological activities (Skulberg 2006). Algal biomass and algae-derived compounds have a very wide range of potential applications, from animal feed and aquaculture to human nutrition a...

One of the main problems in laboratories oyster seed production occurs stage settlement or fixation and metamorphosis larvae. The organisms develop drastic morphological physiological changes at this stage, exposing them to attack by pathogenic microorganisms. Numerous studies indicate that before larval a substrate, they require bacteria stimulate induce process. In study, Japanese (Crassostre...
