The Food of Plankton Organisms. II

On the Artificial Culture of Marine Plankton Organisms

The role of corn starch, sodium smectite and urea formaldehyde in enhancing the food stability of aquatic organisms

Binders are substances of natural or artificial origin and important in the production of aquatic diets. The binders increase the stability and ability to produce diets and prevent pellets from breaking down in water and during transport. Depending on the raw materials used, the method of making the diet and amount of milling used, the type of aquatic species, and the amount of milling, the typ...

Marine Plankton Food Webs and Climate Change

• Some plankton, such as diatoms, grow better at cooler temperatures. Warming may cause other, less palatable, species to replace them, depriving zooplankton and menhaden of their primary food source. • Because phytoplankton are linked to freshwater and nutrient inputs, draught will likely decrease their abundance. Also, when nutrients are reduced, smaller phytoplankton replace diatoms, and the...

Invasibility of plankton food webs along a trophic state gradient

Biological invasions are becoming more common, yet the majority of introduced exotic species fail to establish viable populations in new environments. Current ecological research suggests that invasion success may be determined by properties of the native ecosystem, such as the supply rate of limiting nutrients (i.e. trophic state). We examined how trophic state influences invasion success by i...
