Stimulants of Feeding Behavior in Fish: Analyses of Tissues of Diverse Marine Organisms.
Analyses of the free amino acids, quaternary amines, guanido compounds, nucleotides, nucleosides, and organic acids in extracts of tissues from 10 species of marine teleost fishes and 20 species of invertebrates are reported. With multidimensional scaling techniques, the relative concentrations of the above chemicals in fishes, molluscs, and crustaceans are shown to cluster into separate taxon-...
متن کاملAntitumor Peptides from Marine Organisms
The biodiversity of the marine environment and the associated chemical diversity constitute a practically unlimited resource of new antitumor agents in the field of the development of marine bioactive substances. In this review, the progress on studies of antitumor peptides from marine sources is provided. The biological properties and mechanisms of action of different marine peptides are descr...
متن کاملBiomedical Compounds from Marine organisms
The Ocean, which is called the ‘mother of origin of life’, is also the source of structurally unique natural products that are mainly accumulated in living organisms. Several of these compounds show pharmacological activities and are helpful for the invention and discovery of bioactive compounds, primarily for deadly diseases like cancer, acquired immuno-deficiency syndrome (AIDS), arthritis, e...
متن کاملColour vision in marine organisms.
Colour vision in the marine environment is on average simpler than in terrestrial environments with simple or no colour vision through monochromacy or dichromacy. Monochromacy is found in marine mammals and elasmobranchs, including whales and sharks, but not some rays. Conversely, there is also a greater diversity of colour vision in the ocean than on land, examples being the polyspectral stoma...
متن کاملPopulation structure and identify of macrofouling organisms on marine structures in the coasts of Chabahar Bay
This study has been carried out in the coast of Chabahar Bay from March, 2013 to Febuary, 2014. We sampled macrofouling organisms in three stations. Overall, 40 species of macrofouling organisms were detected in which Barnacles, sponges, Bryozoans, echinoderms, Polychaetes and Gastropods were the major groups. The majority of biomass and highest density were observed in the first half of the se...
