Variation in cell densities and pigment concentrations of symbiotic dinoflagellates in the coral Pavona clavus in the eastern Pacific (Costa Rica)

open access: yesCiencias Marinas, 2008
The density and chlorophyll concentrations of symbiotic dinoflagellates (zooxanthellae) in the eastern Pacific coral Pavona clavus were monitored over the transitional period from rainy to dry season in a seasonal upwelling region and in a nonupwelling ...

A global protocol for monitoring of coral bleaching [PDF]

open access: yes
Coral bleaching and subsequent mortality represent a major threat to the future health and productivity of coral reefs. However a lack of reliable data on occurrence, severity and other characteristics of bleaching events hampers research on the causes ...

Cryptic Species: A Mismatch between Genetics and Morphology in Millepora [PDF]

open access: yes, 2012
Millepore morphology is highly variable and shows signs of phenotypic plasticity. Two species of Millepora are present around the islands of the Bahamas: one exhibiting a strong, blade-like structure, Millepora complanata, and the other having a delicate

On the origin of terpenes in symbiotic associations between marine invertebrates and algae (zooxanthellae). Culture studies and an application of ^(13)C/^(12)C isotope ratio mass spectrometry. [PDF]

open access: yes, 1984
^(13)C/^(12)C ratios of sets of compounds, algal sterols and terpenes, isolated from dinoflagellate symbiont (zooxanthellae)-bearing soft corals and gorgonians were determined.

Aquaculture of corals: the effects of temperature and modifications in photoperiod in performance and growth of Stylophora pistillata [PDF]

open access: yes, 2017
Nowadays, corals have a large economic potential and the increasing demand places an enormous pressure on wild reefs. This issue brings new challenges for coral production in terms of increasing production and efficiency. Besides this, climate change and

MODIFICATION OF SEA ANEMONE BEHAVIOR BY SYMBIOTIC ZOOXANTHELLAE: PHOTOTAXIS

open access: yesThe Biological Bulletin, 1974
The sea anemone Anthopleura elegantissima, with and without endosymbiotic zooxanthellae, was tested for evidence of phototactic behavior. Anemones with zooxanthellae always displayed phototaxis, either positive or negative depending on the experimental light intensity and the light intensity of the habitat from which the animals were taken.

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 [PDF]

open access: yes, 1994
Host glutamine synthetase activity decreases in Pocillopora damicornis (Linnaeus) following exposure of the coral to seawater containing elevated ammonium (20 uM).

Morphological alterations of zooxanthellae in bleached cnidarian hosts

open access: yes, 2008
Studying the morphological changes of zooxanthellae in the host gastroderm is essential to understand the mechanisms of bleaching. Transmission electron microscopy was used to observe samples from four coral species – three collected from a barrier reef in Madagascar (Acropora digitifera (Dana, 1846), Echinopora hirsutissima Milne-Edwards & ...
