    Notes: Abstract Coral reef lagoons have generally been regarded as sinks for organic matter exported from more productive reef front and reef flat zones. The object of this study was to examine the importance of detritus as a carbon source for benthic communities in the lagoon at Davies Reef, central Great Barrier Reef. We report the results of seasonal measurements, taken in 1986, of bacterial numbers and production, protozoan numbers, community primary production and respiration in the sediments of Davies Reef lagoon. Deposition rates of organic matter in the lagoon were also measured. Deposition rates (±1 SE) of carbon ranged from 9.2 (±1.5) to 140.7 (±10.3) mg Cm-2d-1. Deposition rates were highest in winter and spring, lowest in summer. Rates of bacterial production ranged from 4.7 (±0.2) pmol thymidine incorporated g-1 dry wt (DW) h-1 in winter to 23.5 (±1.0) pmol thymidine incorporated g-1 DW h-1 in spring. The number of ciliates ranged from 65 (±10) to 356 (±50) cm-3 through the year and the number of large (≥20 μm) flagellates from 38 (±7) to 108 (±16) cm-3. There were no clear relationships between the sediment organic content, detrital input or temperature and the rates of bacterial processes, community metabolism or the standing stocks of microbes in the lagoon. The relative significance of detritus and in situ primary production as sources of carbon in the lagoon varied with season. In summer and autumn, detritus was less important than primary production as a source of carbon (4 to 27% of total carbon input). In winter and spring, detritus input became more significant in supply of carbon to the sediments (32 to 67% of the total carbon input). The lagoon does not simply act as a sink for carbon exported from the reef flat. We calculate that only 5% of the net reef flat primary production reached lagoon sediments in summer, but nearly 40% in winter.

    Population structure and foraging biology of the predaceous chilean asteroid Meyenaster gelatinosus and the escape biology of its prey (1977)

    Notes: Abstract Observations of the feeding biology of Meyenaster gelatinosus (Meyen) were made between Horcón and the southern Golfo de Penas, Chile. Of 811 sea stars examined, 436 were feeding on individuals representing 30 prey species. M. gelatinosus preys upon almost all the echinoderms and molluscs in its habitat, yet most of the prey species have extremely effective running escape behaviour in which they eventually release their attachment to the substratum, usually assuring that they will be swept to safety. Many of the molluscs exaggerate this by dorsoventral flattening of their mantles, so that they glide even farther. The echinoid Loxechinus albus has a very effective pedicillariae defense. Even at a distance, prey species usually discern foraging M. gelatinosus from non-foraging individuals, and on several occasions were observed touching M. gelatinosus which were eating conspecifics. Comparisons of the sizes of individual M. gelatinosus and their L. albus prey items showed no correlation; none of the prey species except possibly Concholepas choncholepas and M. gelatinosus itself has a refuge in size from attacking M. gelatinosus. The density of M. gelatinosus in 3 of 4 widely separated study areas where such data were collected was 0.04/m2. The mean radius of M. gelatinosus ranged from 150 to 210 mm in five study areas.

    Notes: Abstract Coral reef lagoons are generally regarded as zones of net heterotrophy reliant on organic detritus generated in more productive parts of the reef system, such as the seaward reef flat. The abundance and biomass of sediment infauna were measured seasonally for one year (1986) within the lagoon of Davies Reef, central Great Barrier Reef, to test the hypothesis that macrofaunal biomass and production of coral reef lagoons would decrease with distance from the reef flat and would change seasonally. In general, there were no simple relationships between infaunal standing stock or production and distance from the reef flat or season. Bioturbation by callianassid shrimps negatively affected the abundance of smaller infauna, suggesting a community limited by biogenic disturbance rather than by supply of organic material. Polychaetes and crustaceans were dominant amongst the smaller infauna (0.5 to 2mm) while larger animals (〉 2 mm) were mostly polychaetes and molluscs. Mean biomass of infauna at both sites and all seasons was 3 181 mg C m−2. The smaller animals (0.5 to 2 mm) contributed about 40% of total macrofaunal respiration and production although they represented only 15% of the total macrofaunal biomass. The biomass of macrofauna was about equal to that of the bacteria and meiofauna, while respiration represented 10 to 20% of total community respiration. Consumption by macrofauna accounts for only 3 to 11% of total organic inputs to sediment, with a further 14 to 17% being lost by macrofaunal respiration.

    Man-made structures on marine sediments: Effects on adjacent benthic communities (1982)

    Notes: Abstract This study (1975–1977) examines the effect of man-made structures on natural sand bottom communities in shallow water in San Diego County, southern California, USA. While there were shallow scour effects to 15 m around some artificial reefs, the reefs had no measurable effect on sand ripple patterns, grain size, organic carbon or infauna beyond the scoured areas. Foraging by reef-associated fishes produced profound alterations in the epifauna populations of the sea pen Stylatula elongata. The sea pen densities were 4 to 10 m-2 before the reefs were established, but within 5 mo were eliminated from distances greater than 200 m around the reefs. On the other hand, densities of the tube-building polychaetes Diopatra spp. seemed to be enhanced in the immediate vicinity of the artificial reef. Oil platforms and bridge pilings seem to have much more profound effects on the nearby sand communities than do the relatively small artificial reefs. In addition to the elimination of sea pens, Diopatra spp. densities increased from 〈1.0 m-2 in control areas to as many as 73 m-2 in the vicinity of oil platforms. Grain size and infauna were strongly affected by the oil platform.

    Notes: Summary The binding of diphenylhydantoin, imipramine, diazoxide, cephalothin and cephaloglycin to adult and cord plasma is compared. The free (unbound) fraction of diphenylhydantoin, imipramine and diazoxide in cord plasma is greater than in adult plasma. Although total protein concentration of cord plasma is significantly lower than in adult plasma, this does not satisfactorily explain the lesser binding of these drugs to cord plasma.

    Studies of the renal excretion of probenecid acyl glucuronide in man (1971)

    Notes: Summary The metabolism of probenecid has been investigated in both normal and gouty subjects. To carry out these studies, specific spectrophotometric methods were developed for the measurement of a major metabolite of probenecid, the acyl glucuronide. This conjugate was isolated in semi-pure state and its identity as a mono acyl glucuronide established. Our experiments indicate that about 25% of probenecid is converted to its acyl glucuronide and that only a small amount of the drug is excreted unchanged. About 80% of orally administered14C probenecid could be accounted for in urine, and about half of this was found to consist of metabolites more polar than the parent drug. The renal clearance of probenecid acyl glucuronide was shown to be about 1/3 that of creatinine clearance, whereas the clearance of probenecid was lower. The present findings in man and those of other workers in animals, raise the important question of the possible contribution of these metabolites to the overall pharmacological effects resulting from the administration of probenecid.

    The binding of ketamine to plasma proteins: Emphasis on human plasma (1983)

    Notes: Summary We report for the first time that ketamine (K) is bound as much as 47% to human plasma. It was shown that binding of K to plasma and albumin is dependent on pH; binding is decreased at pH lower than 7.4 and increased at higher pH. This is in concordance with the pKa of K being 7.5; the partition coefficient between an organic phase and buffer was found to be sensitive to small pH changes. Binding of K is also influenced by albumin concentration and the affinity of K for human α1-acid glycoprotein (AAG) is much higher than for human albumin (HSA). The major metabolite nor-K does not appreciably displace K from binding sites on HSA. These findings may explain in part the variability of binding of K observed with different human samples. Human cord plasma exhibits a lower binding of K than adult plasma. This is probably the result of much lower AAG concentration in cord compared to adult plasma; cord and adult plasma albumin levels are known to be only slightly different. Since K has 2 optically active isomers, one of which is more potent than the other, experiments on the binding of racemic and the 2 isomers of K were performed; no differences in binding to AAG were found. We were, however, able to show that tris (butoxyethyl) phosphate (TBEP) can abolish binding of K to AAG. Thus the presence of TBEP would interfere in determining plasma levels and distribution of K. An example would be in the measurement of the partition of K between human red cells and plasma. We determined this ratio in human blood in the absence of TBEP and found it to be similar to that reported for dog red blood cells and plasma.
