A. purpuriferum has tetrasporangia formation which is influenced by daylength, suggesting a relationship between the daylength perception mechanism and photosynthesis. Analyses of photosynthetic pigments showed there was little variation over a range of daylength conditions (4-12 h) and irradiance levels (photon flux densities 2.5-80 panol/m 2 s J). However, both irradiance and daylength history influence the shape of the photosynthesis-irradiance curve. 'The role of photosynthesis in the irradiance-dependency of the short day response in tetrasporogenesis was evaluated.' Dept. of Mar.

Intracellular protein synthesis contributed 20-42% of the total intracellular ~4C fixed and was positively correlated with ambient inorganic N. Decreased protein synthesis following N depletion was balanced by increased intracellular polysaccharide synthesis (22-42% of the intracellular J4C fixed) and by increased extracellular release of H M W material 08-60% of total 14C fixed) which formed a mucous envelope. Lipid synthesis was not correlated with ambient inorganic N, and was about 20% of the intracellular ]4C fixed. Lab. d'Oceanogr., Univ. Libre de Bruxelles, Ave. F.D.

pollutants in the KAP region. Symposium, Marine Science Center, Basrah, Iraq. DouAbul, A.A.Z., organizer; in press. The responses of the marine crustaceans (Carcinus maenas, Crangon vulgaris, and Palaemon serratus) to 96 h exposure to 5 concentrations of benzene, hexane and crude oil were examined. Benzene was the most toxic. Female crabs were more resistant than males and were more sensitive than C. vulgaris. Mar. Sci. Centre, Univ. of Basrah, Iraq. 84:6272 Chaisemartin, Claude, 1983. Comportment of lead salts in a biological linear pattern: alga-mollusc, (Ancylus--Pulmonata). Vie Milieu, 33(1):49-54. (In French, English abstract.) Bioaccumulation of lead in a benthic algae.-Ancylus food chain was investigated in the laboratory. Size or age of the snails affected their lead uptake; lead levels were highest in 'oligo-calcic water populations.' Efficiency of lead assimilation was affected by the rate of food ingestion.

The inorganic and total phosphorus concentrations of coral skeletons from Bermuda, St. Croix and Curacao indicate that a record of seawater phosphorus is preserved which, in certain cases, is consistent with the location and time history of sewage and other phosphorus pollution episodes.

A 'check-list' of behaviors is suggested which indicates species susceptibility to pollution. The 6 questions asked concern formation of 'stationary mass assemblages,' narrow front migrations, inflexible behaviors, unknown or missing life-cycle stages, species niche, and other anthropogenic stresses. Such a check-list could help guide the investigations of pollution assessment teams. Ohm) 84:6275
