“…These baseline profiles, of the as yet uncontaminated system will greatly enhance the monitoring of future adverse effects. Changes in the above mentioned parameters for benthic microbial communities have been shown to be excellent indicators of various impacted systems (White 1983;Parker et al 1984;Smith et al 1985;Smith et al 1982b;Schropp et al 1988).…”

Summary. Benthic microbial communities of the Arthur Harbor area were described by analysis of their cell membrane phospholipid ester-linked fatty acids (PELFA) and metabolic rates. Analysis revealed a biomass averaging 6 nM (phospholipid) or 3.5 x 10 8 cells per gram dry weight (gdw) of sediment for the four sites. Only slight biomass differences were detected between the four peninsula sites. All Arthur Harbor sites were determined to have a biomass similar to the lowest amount reported for a previously described McMurdo Sound site at New Harbor. Community structure based on signature phospholipids indicated only slight differences between the four peninsula sites with greater relative amounts of diatom marker lipids at a deeper site. Bacterial biomarker lipids were also determined in relatively equal proportions for the four Arthur Harbor sites with only one site indicating a somewhat decreased proportion. Metabolic rates of sodium [a4C]-acetate and methyl [3H]-thymidine incorporation into lipid and bacterial DNA respectively also indicated only slight relative differences in microbial communities of Arthur Harbor study sites. Lipid metabolism (14 C-acetate) ranged between 6 and 12 ( x 10 4) DPM/g/h for the four sites with 8 being the average. Bacterial (excluding sulfate-reducing bacteria (SRB)) cell divisions per g per h indicated increased rates at a deeper site with 14 x 10 5, compared to the average (5 x 10 5) for the three remaining sites. Average estimated total bacterial (excluding SRB's) community turnover was on the order of 0.6%/h for the four sites. Metabolic rate comparisons of Arthur Harbor with those of previously determined McMurdo Sound indicated a somewhat increased lipid metabolism and an order of magnitude greater bacterial cell division rate at Arthur Harbor.

We investigated intraspecific variation of the dominant C a~i b b e a n reef building coral Montastrea annularis (Ellis & Solander) in terms of genetic variation (protein electrophoresis), intraspecific interaction and micro/macro morphometry. Our study included 3 sympatric morphotypes. 'Bumpy', 'Massive' and 'Columnar', distinguishable within M annularis populations on the leeward coasts of C u r a~a o and Bonaire (Netherlands Antilles). The g e n e t~c study demonstrated 8 polymorphic and 1 monomorphic loci. The mean number of alleles over all loci was 4.7, and the average heterozygosity (H) over all loci examined was high (0.36). One out of 9 taxonomic units showed a significant heterozygote deficiency; the others matched expectation. The M. annularis morphotypes showed a significant variation in allele frequencies but no fixed differences were found. The 'Columnar' and 'Bumpy' morphotypes were more similar with a genetic distance of 0.07. The 'Massive' morphotype demonstrated larger genetic distances: 0.13 with 'Columnar' and 0.16 with 'Bumpy' The 'Bumpy' morphotype was dominant over the other 2 morphotypes in the intraspecific interaction experiments, and 'Massive' was dominant over 'Columnar' The percentage of interactions was lower in intra-morphic experiments Of the 22 micro-morphometric parameters examined, 14 showed significant differences between the 3 morphs. In addition the mean number of polyps per cm2 was very different: values ranged from 28.55 for 'Bumpy' to 40.97 for 'Columnar'

“…Other investigations published since the reviews in Snyder's (1972) book Ether Lipids report the plasmalogens in coral (Parker et al, 1984); molluscs, including abalone (de Koning, 1966;Joh and Hata, 1979), a top shell (Joh and Hata, 1979) and bivalves (Sampugna et al, 1972;Joh and Hata, 1979;Chelomin and Zhukova, 1981); and in a tunicate (Hayashi et al, 1979). Plasmalogen analyses of fish tissue other than gills are: brain Driedzic et al, 1976;Kruglova, 1979), muscle mitochondria (Wodtke, 1981), optic nerve (Matheson et al, 1981) and erythrocyte membranes (Nelson, 1972;Warren et al, 1979).…”

Abstract--1. Lipids constituted 0.6-2.2~ wet wt of the gills of 11 species of aquatic animals (4 bivalves, a crustacean and 6 fishes).2. Phospholipids, largely phosphatidylcholine (PC) and phosphatidylethanolamine (PE), are major components of all species.3. The plasmalogen contents of these lipids were 47-291/~mol/g, with the highest values found for bivalve gill total lipids and the catfish phospholipid fraction.
