Amino Acid Content of Zooxanthellae Freshly Isolated from Pocillopora damicornis

McAuley, PJ (University of Hawaii Press, 1994-07)

Total amino-N content and glutamine to glutamate ratios (gln: glu) were determined in zooxanthellae freshly isolated from colonies of the coral Pocillopora damicornis (Linnaeus) incubated in ambient seawater or in seawater ...
Carbohydrate, Lipid, and Protein Composition of Zooxanthellae and Animal Fractions of the Coral Pocillopora damicornis Exposed to Ammonium Enrichment

Achituv, Y; Ben-Zion, M; Mizrahi, L (University of Hawaii Press, 1994-07)

The carbohydrate, lipid, and protein composition of coral tissue and zooxanthellae were compared in Hawaiian Pocillopora damicornis (Linnaeus) colonies kept at different ammonium levels. Corals were maintained at two ...
Effect of Ammonium Enrichment on Animal and Algal Biomass of the Coral Pocillopora damicornis

Muller-Parker, G; McCloskey, LR; Hoegh-Guldberg, O; McAuley, PJ (University of Hawaii Press, 1994-07)

Algal and animal biomass parameters of colonies of the Pacific coral Pocillopora damicornis (Linnaeus) were measured as a function of time of exposure to elevated concentrations of seawater ammonium (20 and 50 uM [(NH4)2S04]) ...
Effect of Ammonium Enrichment on Respiration, Zooxanthellar Densities, and Pigment Concentrations in Two Species of Hawaiian Corals

Stambler, Noga; Cox, Evelyn F; Vago, Razi (University of Hawaii Press, 1994-07)

Small branch tips or "nubbins" of two species of Hawaiian corals, Pocillopora damicornis (Linnaeus) and Montipora verrucosa Vaughan, were exposed to four ammonium concentrations, ammonium-stripped < 2 uM), ambient (~2 ...
Effect of Ammonium-supplemented Seawater on Glutamine Synthetase and Glutamate Dehydrogenase Activities in Host Tissue and Zooxanthellae of Pocillopora damicornis and on Ammonium Uptake Rates of the Zooxanthellae

Yellowlees, D; Rees, TAV; Fitt, WK (University of Hawaii Press, 1994-07)

Host glutamine synthetase activity decreases in Pocillopora damicornis (Linnaeus) following exposure of the coral to seawater containing elevated ammonium (20 uM). Zooxanthellae isolated from these corals exhibited lower ...
Effect of Exogenous Nitrogen Levels on Ultrastructure of Zooxanthellae from the Hermatypic Coral Pocillopora damicornis

Berner, Tamar; Izhaki, Ido (University of Hawaii Press, 1994-07)

Branches of the hermatypic coral Pocillopora damicornis (Linnaeus) were exposed for 2, 4, 6, and 8 weeks to ammonium concentrations of < 1 uM (nutrient-stripped), 2 uM (seawater as a control), 20 uM, and 50 uM (enriched), ...
Effects of Water Velocity on Respiration, Calcification, and Ammonium Uptake of a Porites compressa Community

Atkinson, MJ; Kotler, E; Newton, P (University of Hawaii Press, 1994-07)

Colonies of Porites compressa Dana were placed in a 10-m-long flume to form a community of coral. Ammonium uptake (N uptake) rate, respiration rate, and calcification rate were measured at different water velocities, ranging ...
Elemental Composition of the Coral Pocillopora damicornis Exposed to Elevated Seawater Ammonium

Muller-Parker, G; Cook, CB; D'Elia, CF (University of Hawaii Press, 1994-07)

The elemental composition (C, N, and P) of zooxanthellae and host tissue from the coral Pocillopora damicornis (Linnaeus) was determined after maintenance in flowing seawater with 20-uM and 50-M ammonium enrichments for ...
Nutrient Limitation in the Symbiotic Association between Zooxanthellae and Reef-building Corals

(University of Hawaii Press, 1994-07)

A workshop held at the Hawaii Instititue of Marine Biology, Coconut Island, Hawaii, 25 to 30 August 1991.
Nutrient Limitation in the Symbiotic Association between Zooxanthellae and Reef-building Corals: The Experimental Design

Stambler, Noga; Jokiel, Paul L; Dubinsky, Zvy (University of Hawaii Press, 1994-07)

The question of nutrient limitation and of its regulatory effect on population densities of zooxanthellae in hospice was studied by an international team of researchers during an intensive 5-day workshop. Participants ...
Population Dynamics of Symbiotic Zooxanthellae in the Coral Pocillopora damicornis Exposed to Elevated Ammonium [(NH4)2 SO4] Concentrations

Hoegh-Guldberg, Ove (University of Hawaii Press, 1994-07)

Division synchrony and growth rate of symbiotic zooxanthellae was investigated for populations living in colonies of the reef-building coral Pocillopora damicornis (Linnaeus) exposed to different concentrations of ...
Ratio of Energy and Nutrient Fluxes Regulates Symbiosis between Zooxanthellae and Corals

Dubinsky, Z; Jokiel, PL (University of Hawaii Press, 1994-07)

Ambient irradiance levels determine the rate of carbon influx into zooxanthellae at any given time, and thereby the energy available for the whole coral symbiotic association. Long-term photoacclimation of zooxanthellae ...
Resource Partitioning by Reef Corals as Determined from Stable Isotope Composition II. 15N of Zooxanthellae and Animal Tissue versus Depth

Muscatine, L; Kaplan, IR (University of Hawaii Press, 1994-07)

The pattern of resource partitioning versus depth for corals collected in February, 1983, from Jamaica was investigated by analyzing their stable nitrogen isotope composition. Observations were made on isolated ...
Results of the 1991 United States-Israel Workshop, "Nutrient Limitations in the Symbiotic Association between Zooxanthellae and Reef-building Corals"

Jokiel, Paul L; Dubinsky, Zvy; Stambler, Noga (University of Hawaii Press, 1994-07)

An intensive research effort was organized as a 1-week workshop with the specific goal of resolving difficult questions concerning whether or not zooxanthellae are nutrient limited within host corals. Over 30 scientists ...
