    Notes: Abstract Corals in an in situ respirometer exposed to suspended peat during the day greatly decreased net oxygen production, probably due to a reduction of intensity and spectral quality of light reaching the symbiotic zooxanthellae. Net production returned to pre-exposure levels after the chambers were cleared; the corals showed no behavioral effects. In contrast, after exposure during the night, corals displayed clearing behavior (such as extreme distension of the coenosarc and trapping of peat particles in thick clumps of mucus) and an increase in respiration rate comparable to the decrease in net production observed during the daytime exposure. The following morning, net production values were significantly lower than pre-exposure production values although ambient light intensity was slightly higher. This decrease in production as well as a 22% reduction of chlorophyll content in the coral tissue indicated loss of zooxanthellae from the stressed corals. Long-term exposure to such a stress could reduce coral growth rates and substantially alter coral reef communities.

    Effects of carbon dioxide concentration on coral photosynthesis (1983)

    Notes: Abstract The effects of inorganic carbon concentrations on photosynthetic oxygen evolution of isolated zooxanthellae and coral tips from the hermatypic coral Seriatopora hystrix were measured in the laboratory using an oxygen electrode. Whole coral colonies of Stylophora pistillata were examined in situ, using a bioassay respirometer. Inorganic carbon concentrations above 2.3 mM, the ambient concentration of reef water, generally did not stimulate photosynthesis. These results indicate that inorganic carbon is not limiting to coral photosynthesis and that respiratory carbon dioxide production by the coral host probably has little effect on the photosynthetic rates of its symbiotic zooxanthellae.

    A comparison of the metabolism of bicarbonate 14C and acetate 1-14C and the variability of species lipid compositions in reef corals (1983)

    Notes: Abstract Branching heads of symbiotic corals were pulse labeled with either 14C-acetate or 14C-bicarbonate for 1.33 h and the distribution and loss of label was then followed for 16d. The patterns of incorporation and washout were similar for both tracers. Non-solvent-extractable radioactivity (1/3 of the total) was divided into a CaCO3 and an organic fraction, both of which exhibited small if any decrease in radioactivity over 16d. In contrast, total solvent extractable (lipid) radioactivity (2/3 of the total) decreased during the washout period with the first half-life for bicarbonate at 2 d, the second at 4 d and the third could not be measured because of the persistence of a constant amount of radioactivity (18% of Day 1 value) from Day 8 to 16. Of the total retained activity, the zooxanthellae fraction contained between 8–18% from Day 1 to 5. The percentage of total animal (host) radioactivity in lipids rose from 35–40% at 0 time after tracer exposure to 70–90% at 60 min. The majority of 14C fixed into lipids was recovered in the fatty acyl moieties and not in the glycerol moiety as had been previously reported a number of times. These studies suggest that photosynthetically fixed carbon is immediately synthesized into lipid, which is translocated to the host. Analyses of the fatty acid compositions of triacylglycerols (TG) and wax esters (WE) of 40 species of coral from a small patch reef were made. In aposymbiotic species the absence of zooxanthellae appeared to be correlated with higher levels of total lipid, lower percentages of saturated fatty acids and lower TG/WE ratios than in species with symbionts.

    Notes: Abstract The catalytically inactivating subset within rabbit serum polyclonal antibody to the solubilized, purified 55,000 to 60,000 dalton active fragment of rat liver microsomal β-hydroxy-β-methylglutaryl coenzyme A reductase immunoinactivates this enzyme with little or no diminution of effect by enzyme catalytically inactivated by incubation of microsomes with ATP,Mg++. Reactivation of inactive enzyme with ethanol-treated rat liver phosphatase restores antibody affinity showing that the catalytically inactivating subset of antibody exhibits marked or complete affinity for the active enzyme over the ATP,Mg++-inactivated form. This means that immunoinactivation using this antibody is not a valid way of measuring changes in the specific activity of the enzyme via phosphorylation-dephosphorylation. Preference for the active enzyme has not been obvious because when different amounts of enzyme activity are used in immunotitrations of samples of low activity, apparent differences in specific activity are observed when none actually exist. If precautions are not taken, results are obtained supporting phosphorylation by using an antibody that is not capable of distinguishing it.

    Increasing growing points and oil yields in lavender by growth regulator sprays (1983)

    Notes: Abstract Immature plants ofLavandula angustifolia x L. latifolia (cv. Twickle Purple) were sprayed with Atrinal and P293 when the growing shoots bore four to six expanded leaves. Atrinal increased the number of inflorescences per plant by stimulating otherwise dormant axillary buds on the shoots of the current season. The number of nonflowering shoots arising on older wood was also increased. The number of florets and the fresh weight per inflorescence were reduced, but the number of florets per plant was increased overall. Oil content per plant was doubled without altering oil composition or floret structure. Flower stalks were shortened below and between the floral nodes. Atrinal sprays achieved a machine-harvestable canopy in 3-year-old plants. Untreated plants required a full year longer to develop similar canopies. P293 and manual disbudding were not as effective as Atrinal. It is suggested that such spray treatments have a useful potential in reducing the time required for the development of the mature canopy form, and so obtaining earlier financial returns on establishment costs.

    The relationship of headache occurrence to barometric pressure (1980)

    Notes: Abstract A total of 75 people residing in the metropolitan Boston area who had frequently recurring headaches kept a headache diary for one month beginning March 1975. Data were also collected about barometric pressure during this time. We found that the probability of headache severity on any day was independent of the effects of time. An inference of this, supported by other findings in this study, is that headache occurrence is minimally affected by time-related phenomena such as barometric pressure readings or changes..
