DNA; these results appear to preclude the use of light-dependent D N A accumulation as a measure of phytoplankton growth rate in the oligotrophic oceans. Hawaii Inst. of Geophys., Univ. of Hawaii, Honolulu, HI 96822, USA. 86:7028

Carbon incorporation and respiration (~4C-labelled acetate, glucose, glutamate and trimethylamine) rates generally decrease with water depth and depth in the upper 9 cm of sediment. In most experiments, 1 atm control rates were higher than those observed in-situ, supporting the notion that deep-sea sediment populations contain barotolerant and barophilic microorganisms in varying proportions.

Both eye and extraocular receptors are discussed, with an emphasis on organisms possessing highly complex eyes (crustaceans, molluscs, and some polychaete annelids), many of which exhibit extreme sensitivity, good spatial resolution and sometimes multiple spectral channels. The relationship between photoreception and circadian systems is explored. Dept. of Biol. Sci., Univ. of Maryland, Catonsville, MD 21228, USA. (gsb) 86:7032

91(2): 149-159. Total lipid was depth-dependent and similar to levels in temperate mesopelagic species, while copepod wax ester content was higher than in subtropical species. Three predator-prey relationships were suggested by lipid data and confirmed by gut contents. In contrast to terrestrial plants and temperate marine species, even-carbon number paraffins were predominant in 80% of the species tested, suggesting the presence of an unusual biochemical pathway.

At an intertidal study site in southern California the daily settlement of barnacle cyprids was not significantly cross-correlated with wind speed or direction but was significantly cross-correlated with the maximum daily tidal range at lags of + 1 to + 4 days; peak settling occurred several days before the spring tide. This pattern of settlement, nearly identical to that of Pachygrapsus crassipes, suggests that cyprids may be transported onshore in slicks over tidally forced internal waves.
