Bioprospecting Marine Plankton
The ocean dominates the surface of our planet and plays a major role in regulating the biosphere. For example, the microscopic photosynthetic organisms living within provide 50% of the oxygen we breathe, and much of our food and mineral resources are extracted from the ocean. In a time of ecological crisis and major changes in our society, it is essential to turn our attention towards the sea t...
متن کاملMixotrophy in the Marine Plankton.
Mixotrophs are important components of the bacterioplankton, phytoplankton, microzooplankton, and (sometimes) zooplankton in coastal and oceanic waters. Bacterivory among the phytoplankton may be important for alleviating inorganic nutrient stress and may increase primary production in oligotrophic waters. Mixotrophic phytoflagellates and dinoflagellates are often dominant components of the pla...
متن کاملClimate change and marine plankton.
Understanding how climate change will affect the planet is a key issue worldwide. Questions concerning the pace and impacts of climate change are thus central to many ecological and biogeochemical studies, and addressing the consequences of climate change is now high on the list of priorities for funding agencies. Here, we review the interactions between climate change and plankton communities,...
متن کاملGlucose content of the body fluid in marine annelids.
Bahl (1) maintains that there are 100 mg. of glucose in 100 cc. of earthworm blood but that there is no sugar in the coelomic fluid. On the other hand, Damboviceanu (2) found no reducing sugar in the plasma from Xipunculus n&us. There is no information in the literature concerning the sugar content of the body fluid in marine annelids from the American coast. A series of analyses was, consequen...
متن کاملDetermination of trace elements in marine plankton by inductively coupled plasma mass spectrometry (ICP-MS).
A method has been developed for the determination of 23 elements in marine plankton in which inductively coupled plasma (ICP) source mass spectrometry (MS) was used to quantify the elements in the solution after digestion in a mixture of hydrofluoric and nitric acids in sealed PTFE vessels in a microwave field. The procedure was validated by the analysis of a standard reference soil (SRM 2709 S...
