M. Sears and D. Merriman, eds., SpringerVerlag; pp. 614-621. Reported here are the results of a retrospective survey of U.S. geologists designed to reveal the patterns and processes of acceptance of the theory of plate tectonics/continental drift, especially during the key period of the 1960's. The role of theory in shaping research efforts and influencing data interpretation is considered. (mjj)

Very low fish catches were recorded at 2 primary stations. The catch of benthos was much greater than the previous year as most infaunal species had emerged from the sand. The phenomenon was assumed to be caused by low oxygen concentrations in bottom water following the collapse of a bloom of the dinoflageUate Ceratium furca.

Transfer of biomass up the food web to larger organisms cannot always be calculated based on predation alone. Somatic growth augments this transfer and reproduction impedes it. Equations accounting for the effects of somatic growth and reproduction are derived; conditions under which these factors can be ignored are defined. Food for each species need not be specified. Production of Mysis relicta is calculated as an example and is found to be 25% greater when somatic growth is accounted for.

Diurnal differences were found in total biomass in the upper 225 m with one-third to two-thirds of the nighttime biomass in the upper 56 m of water being redistributed below this depth during the day. For most copepods considered, this change was caused by diel vertical migration; larger zooplankters could have descended below 225 m or avoided capture in the surface layers more successfully during the day than at night.

However, as the larvae grow their effect increases, and they may cause prey mortality severe enough to affect their own growth near the age of metamorphosis. 198 Yarmouth Rd., Lowestoft, Suffolk NR32 4AB, UK.

Tropical chlorophyll profiles are simulated by a model which assumes phytoplankton oscillate vertically around a critical depth, assimilating nutrients at the deeper levels and receiving more light above. Such oscillations have not been observed, perhaps due to wide variance in individual cell oscillation periods and phases. Model results are compared with actual data.

Fasham, M.J.R. and T. Platt, 1983. Photosynthetic response of phytoplankton to light: a physiological model. Proc. R. Soc, Lond., (B)219(1217):355370. A theoretical representation for the relationship between photosynthesis and light in phytoplankton is based on a simple model of processes associated with electron flow through photosystem II. Photoinhibition is represented as an impediment to this electron flow. Examples are shown of fits to various typical light saturation curves for natural assemblages of marine phytoplankton. Size of the photosynthetic unit of PSII is important. Photoadaptation is discussed in terms of changes in the light saturation curves due to modifications in the number or size of the photosynthetic units. Inst. of Oceanogr.

Herbivorous zooplankton were more consistently associated with the estimated primary productivity maximum than with the deeper chlorophyll maximum, which represented a phytoplankton biomass maximum. Predators were positively correlated with abundant potential prey species. Variations in body length with depth suggest that these fine-scale patterns were sufficiently stable to influence zooplankton growth.

Heterogeneity patterns in nutrients, macrozooplankton biomass, and integrated water column chlorophyll and primary production are described on spatial scales ranging from less than one to several thousand km and on temporal scales ranging 1 day to 12 years. Fluctuations in these properties represent an index of the biological response of the ecosystem to physical forcing. Heterogeneity in each property was low on all scales. Diel changes were evident only in macrozooplankton biomass; no seasonal cycles were detected.

Dynamics of the rotifer, Synchaeta vorax, and tintinnids of the genus Tintinnopsis were studied. In early April when surface temperature exceeded 6°C, the rotifer population started to grow rapidly; thereafter the population increased exponentially for 6 weeks. Estimates, admittedly rough, of consumption of phytoplankton by rotifers and tintinnids in their most dynamic phase approximated phytoplankton production, indicating that the 2 groups of predators are highly important components in the community. Through high turnover, they effectively utilize the spring phytoplankton bloom and serve as a link between primary and secondary producers. Kristineberg Mar. Biol.

Results of model simulations in which primary production and abundance of plankton-feeding fish were the primary forcing functions indicated that predatory interactions could regulate the size structure of marine zooplankton. When planktivorous fish were rare, large herbivores and invertebrate predators were dominant, as is the case in freshwater communities. However, model results did not correspond with recent changes in zooplankton and fish in the North Sea. Zooplankton there may be foodrather than predator-limited; more complex models are needed.

During the course of the bloom, there was an increase in ribulose1,5-bisphosphate carboxylase activity, carbon fixation per cell, and the light intensity at which photosynthesis became saturated; there was a decrease in dark carbon fixation.

Res., 41(4):731746. Culture experiments with diatoms demonstrate that, as an iron source, freshly prepared coUoidal ferric hydroxide can produce better cell yield than goethite or hematite; aging or heating of the prepared ferric hydroxide reduces cell yield. Reduction in cell yield can be prevented by adding EDTA prior to, but not after, aging or heating of the ferric hydroxide. Results suggest that the ability of colloidal iron to provide a source of metal for phytoplankton is related to colloid thermodynamic stability.

Under laboratory conditions, vegetative structure reduced predation rates of pinfish and Atlantic croaker but did not affect those of red drum and speckled trout; the 2 former were inefficient, needing several strikes (thus repeated detection) before successfully capturing prey. Although pinfish and speckled trout appeared to be strictly visual feeders, Atlantic croaker and red drum apparently could detect shrimp through other sensory mechanisms; this did not appear related to the effect of vegetative structure on predation rates.

The Santa Catalina Basin megafauna constitutes a major component of the benthic biomass with ophiuroids accounting for 99% of the community abundance and standing crop. Includes bottom photographs.

The abundance and diversity of epifaunal peracaridan crustaceans were functions of seagrass species and biomass per square meter. Infaunal abundance, also affected by seagrass species and biomass, was greatest in bare sand. Seagrass biomass and growth form effects on the foraging behavior of predators of peracarids are discussed. Sea Education Assoc., P.O. Box 6, Woods Hole, Mass. 02543, USA. (mjj)

Shelf Sci., 17(2): 143-158. Species composition changed noticeably with depth and season; middle shelf areas were transitional with taxa characteristic of both inner and outer sites. Bryozoa, Cnidaria, Porifera, Annelida and MoUusca represented the richest taxonomic groups of the 1175 taxa collected. Both diversity and biomass of invertebrates from hard bottoms exceeded those previously reported for sand bottoms. Sponges accounted for >60% of the total invertebrate biomass collected. High diversity values were attributed primarily to habitat complexity, exhibiting no discernible pattern with depth or latitude. South Carolina Mar. Res. Inst., Box 12559, Charleston, SC 29412, USA.

Starved hydrophilic Vibrio sp. and hydrophobic Pseudomonas sp. went through a dwarfing phase consisting of fragmentation, continuous cell size reduction, and intense metabolic activity. This process was studied at both nutrient-enriched and nutrient-deficient interfaces. Hydrophilic bacteria became smaller and had a higher endogenous metabolic rate at nutrient-deficient surfaces than in the liquid phase. This was not the case for hydrophobic bacteria.

The characters of these closely related species agree with the present definition of Eurycope, but several features make them distinct from their congeners. The most unusual trait is the very elongate stylet on the male pleopod II which is considered to be a derived trait that has evolved independently on numerous occasions in the Asellota Janiroidea.

Most researchers suggest that ice algae are derived from sparse water column assemblages that become trapped during ice formation and then develop in-situ; others have suggested that forming ice crystals concentrate algal cells. Weddell Sea ice algae were concentrated by a physical mechanism described here; how such a process may accumulate planktonic forms in ice communities is explained.

Photosynthesis was reduced by ~75% during the period of increased turbidity. It took ~ 5 weeks for the estuary to clear. Although primary production was greatly diminished, flux of particulate C was high; the total production estimated to have been lost amounted to only ~2% of the total particulate C flux just after the eruption. That the turbidity did not induce a severe fall in the phytoplankton population is evidence that phytoplankton biomass is mostly a function of import from the Columbia River, rather than in-situ production.

Copper is contained in a number of enzymes and proteins, but except for azurin, plastocyanin and copper-containing cytochrome c oxidase found in some bacteria, all copper enzymes and proteins are found only in eukaryotes. In the Early and Middle Precambrian, copper compounds were very insoluble and might have been unavailable to organisms. Copper became Cu(II) upon rise of the atmospheric oxygen pressure, thus available in the Mid-Proterozoic when the first eukaryotes seem to have appeared on Earth. Thus, copper may be considered an indicator for atmospheric evolution (from anoxygenie to oxygenic) and the evolution of higher organisms. Dept. of Chem., Juniata Coll. Huntingdon, Penn. 16652, USA. 84:2385 Raup, D.M., 1983. On the early origins of major biologic groups. Paleobiology, 9(2): 107-115.

Major biological groups (phyla, classes, orders) in an adaptive radiation tend to appear early in the geologic record. This commonly observed phenomenon is shown to be an 'artifact of the geometry of the evolutionary tree,' based on theoretical and empirical analysis. Only cladogenetic (branching) aspects of the problem are considered. The morphological distinctness of the major groups as soon as they appear in the fossil record requires ecological explanations.

Ecological models generally have been based on the principle of optimization, in which a dependent

331

variable is optimized based on a cost-benefit function. However, in cases where the performance of an individual affects the performance of other members of the population the optimization approach is invalid and game theory should be used instead; some such cases are described. The background and uses of game theory are discussed here, emphasizing areas not detailed by Maynard Smith and Price, originators of the biological variant of game theory. Includes 409 references.
