13C/12C ratios in marine invertebrates from reducing sediments: confirmation of nutritional importance of chemoautotrophic endosymbiotic bacteria Marine & Ocean Science
Spiro, B.; Greenwood, P.B.; Southward, A.J.; Dando, P.R..
ABSTRACT: The carbon isotope composition (6l3C%0) of the tissues of benthic invertebrates usually ranges from - 16 to -20. In contrast we report that several common bivalve molluscs belonging to the superfamily Lucinacea and several small species of Pogonophora show much greater depletions, ranging from -23 to -31 in the bivalves and from -35 to -46 in the pogonophores. These bivalves and pogonophores live in reducing sediments where the concentration of dissolved sulphide is low, usually < 1 PM. The gills of the bivalves and the trophosome tissue of the pogonophores contain intracellular or sub-cuticular bacteria. The bacteria are autotrophs, as shown by ribulosebisphosphate carboxylase activity of extracts of the bacteria-containing tissues....

2-Aminoethylphosphonic acid in Monochrysis Marine & Ocean Science
Baldwin, M.W.; Braven, J..
2-Aminoethylphosphonic acid has been identified in a combined form in the lipid and protein fractions of the phytoplankton Monochrysis lutheri Droop. Identification of this compound in marine sources has hitherto been confined to the animal kingdom.

A change in the zooplankton of the central North Sea (55 degree to 58 degree N): A possible consequence of changes in the benthos Marine & Ocean Science
Lindley, J.A.; Gamble, J.C.; Hunt, H.G..
The mesozooplankton taken in continuous plankton recorder samples from the Central North Sea has changed from being numerically dominated by holoplanktonic calanoid copepod species from 1958 to the late 1970s to a situation where pluteus larvae of echinoid and ophiuroid echinoderms have been more abundant than any single holoplanktonic species in the 1980s and early 1990s. The abundance of the echinoderm larvae as a proportion of the zooplankton taken in the samples has followed a continuous increasing trend over the Dogger Bank, but off the eastern coast of northern England and southern Scotland the increase did not become obvious until the 1980s. This trend is consistent with reported increases in abundance of the macrobenthos. It is proposed that...
