Production of superoxide ions within tissues of the symbiotic sea anemone Aiptasia pulchella was de- tected using SOD-inhibitable cytochrome c reduction and quantified by SOD-inhibitable reduction of nitro blue tetrazolium (NBT). Intact aposymbiotic

1. The hermatypic coral, Pocillopora damicornis was incubated in the laboratory and in its reef habitat with Na214CO3 for 1-24 hours. Controls were incubated in darkness. 14C fixation in light exceeded that in darkness.2. Fractionation of corals labe

Synthetic host factor (SHF) was used in parallel with crude cnidarian’s host factor (CHF) to investigate their effects on both photosynthetic carbon metabolism and the first step of lipid synthesis in the symbiotic dinoflagellates Symbiodium purchr

SUMMARY Temperature-induced bleaching in symbiotic cnidarians is a result of the detachment and loss of host cells containing symbiotic algae. We tested the hypothesis that host cell detachment is evoked through a membrane thermotropic event causing

A wide range of both intrinsic and environmental factors can influence the population dynamics of algae in symbiosis with marine cnidarians. The present study shows that loss of algae by expulsion from cnidarian hosts is one of the primary regulators

The metabolite exchange in alga–invertebrate symbioses has been the subject of extensive research. A central question is how the biomass of the algal endosymbionts is maintained within defined limits under a given set of environmental conditions de

Anthozoan host factors are components of host animal homogenates which elicit the release of newly fixed carbon by symbiotic dinoflagellates in vitro. The host factor active component of an homogenate of the reef coral Pocillopora damicornis has rece

Symbiotic dinoflagellates are abundant in the endoderm cells of tropical marine anthozoans, but the cell-specific density (CSD) of symbionts has not yet been investigated. In this study we used mechanical and enzymatic methods of maceration, and stai

We used light, scanning, and electron microscopy to investigate the ultrastructure of desmocytes in the scleractinian Stylophora pistillata from the Red Sea. Desmocytes are abundant on the calicoblastic epithelium, numbering up to 150 per mm2 in the

Reef-building corals and other tropical anthozoans harbor endosymbiotic dinoflagellates. It is now recognized that the dinoflagellates are fundamental to the biology of their hosts, and their carbon and nitrogen metabolisms are linked in important wa
