Density Of Benthic Communities Research Articles

Observations on a solar saltworks near Burgas, Bulgaria

Data on biota and nutrients in solar ponds of a saltworks near Burgas, Bulgaria, were obtained. Surveys of the biota were undertaken, and records from management officials gave information on biological and physical conditions related to salt production. The decrease in the quality and quantity of sodium chloride harvested that began 10 to 15 years before the study, may be related to the high levels of plankton, combined nitrogen and phosphate, and the large accretion of bottom sediments and density of benthic communities. Biological management can improve the quality and quantity of the sodium chloride produced by the saltworks.

Density of Marine Benthic Communities off West Africa

RECENTLY, Thorson1 has suggested that a series of related marine benthic communities might occur on level sea-bottoms from the Arctic to the tropics, similar communities occurring on similar deposits irrespective of latitude, and he directed attention to the possibility of studying, in these communities, growth-rates and recruitment of stock under similar ecological conditions in cold and in warm seas. Although there is now fairly extensive knowledge of the density of benthic communities in temperate, boreal and arctic waters, there is no comparable information from tropical seas; Sparck2 has presented data derived from a few quantitative stations worked in the Gulf of Guinea with a van Veen sampler, but these were mostly in deep water off the continental shelf. All the other quantitative surveys in the tropics appear to have been concerned with the fauna of coral reefs.
