The constancy of weight-specific production over the entire size range of E. pacifica was investigated, using both direct (summing growth, molting and reproduction) and indirect ('assimilation minus metabolism and leakage') measures of production. Production was determined in terms of both C and N at 8 ° and 12°C. Complete C and N budgets were constructed at both temperatures; efficiencies of assimilation, C net growth and cumulative net production were calculated. Measured and predicted ingestions were compared to test budget accuracy. Mar. Sci. Inst., Univ. of Calif., Santa Barbara, Calif. 93106, USA. (mjj) 82:6266 Shih, Chang-Tai and Nell Stallard, 1982.

There is a discontinuity between samples from different latitudes as regards abundance and number of species of Acantharia. The latitude at which the abundance difference occurs varies, in accord with previously-noted differences in primary production, phytoplankton, and mesopelagic fishes, thus suggesting a relationship with thermal fronts.

A one-year program yielded 72 tintinnine species in hauls from 7 different depths. Six dominant species accounted for 30-93% of the total numerical abundance. Over 90% of the tintinnine population inhabited the surface 100 m; species occurring in deeper waters were rarely or never found near the surface. The Biol. Inst., YU-50001 Dubrovnik, Yugoslavia.

Water turbulence was measured before and after passing through the latticework structure of branches of the bushy red alga G. nudifrons. Turbulence was reduced by passage through the plant's structure, but above a critical velocity (6-12 cm/s) microturbulence was generated. Microturbulence may influence nutrient uptake and gas

Photosynthesis of intertidal brown algae during and after periods of emersion: a renewed search for physiological causes of zonation. Mar. Ecol.-Prog. Set., 8(3): 301-308. CO2-exchange of emersed plants and O2-exchange of submersed plants were measured in 5 species of brown algae from different tidal heights in Ireland and Helgoland. The photosynthesis of emersed fucoids and Laminaria digitata increased as up to 25% of tissue water was lost, but then declined with further desiccation. Recovery from severe desiccation took ~ 2 h in all species, regardless of their typical position on the shore, but the extent of recovery from a given degree of desiccation was greater in upper shore species. It is in the extent of recovery of photosynthesis after desiccation that intertidal brown algae show the clearest correlation with their heights in the zonation pattern on European shores.

Sulphur uptake by salt grasses, mangroves, and seagrasses in anaerobic sediments. Geochim, cosmochim. Acta, 46(6):11211124. Stable S isotope analyses show that estuarine plants rooted in anoxic sediments incorporate substantial amounts of 34S-depleted sulfides, or oxidation products thereof. In roots, this incorporation predominates over sulfate uptake from interstitial water. Either the plants incorporate normally toxic sulfides, or they are creating and using a specialized nutrient pool of oxidized sulfides at the root-sediment interface. Harbor Br.
