Investigation was made into the influence of changing light
intensity on the organic and elemental composition of two species of
marine diatoms, Ditylum brightwellii and Skeletonema costatum.
Analysis was made of the relative changes in soluble and insoluble
carbohydrate; polar, non-polar, and total lipid; amino acids; proteins;
and total carbon,...
The nature of the bioluminescence of Gonyaulax catenella is
similar to that observed for other dinoflagellates in culture, showing
photoperiod-entrained rhythms of luminescence and stimulability
with relatively constant luminescent capacity during scotophase. G.
catenella is very sensitive to stimulation and photoinbibition. The
nature of the response to stimulation by bubbling...
The purposes of this investigation were to measure the relative
levels of enzymatic and respiratory metabolism of some vertically
migrating mesopelagic fishes collected from the ocean waters off
Oregon and to modify and adapt an enzyme method for use as a measure
of metabolic activity at sea with a minimum...
