The effects of elevated UV-B radiation on productivity and bleaching of zooxanthellae in the coral Montastraea Faveolata.
They can grow so much they block light needed by zooxanthellae, eventually killing coral and turning the once rainbow formations deathly white.
Because squid pellets were such a small portion of the control anemone's total ingested diet and photosynthate exuded by zooxanthellae within anemones likely reduced the squid pellet's contribution even more, we predicted that consumption of squid pellets by control anemones would not enhance their growth and reproduction relative to anemones not receiving squid pellets.
When stressed, the polyps expel their generally brownish zooxanthellae, exposing their white limestone skeletons through their translucent tissues.
The discoloured band is a mark of death, indicating where the bacterial infection has killed the zooxanthellae. The coral host suffers from cellular damage and starves without its major energy source, and usually does not recover.
Several studies have addressed how cnidarians in symbiotic associations with zooxanthellae cope with high oxygen concentrations during the day (e.g., Shick and Dykens, 1985; Levy, 2006), but little is known about how they cope with low oxygen levels at night.
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.
Effects of light of altered spectral composition on coral zooxanthellae associations and on zooxanthellae in vitro.
Effects of host nutritional status and seasonality on the nitrogen status of zooxanthellae in the temperate coral Plesiastrea versipora (Lamarck).
Proteomic shifts between day and night in Acropora millepora planulae lacking zooxanthellae
Observations on the histology and photosynthetic performance of "solar-powered" opisthobranchs (Mollusca, Gastropoda, Opisthobrachia) containing symbiotic chloroplasts or zooxanthellae. Org.
Gas-exchange studies with the staghorn coral Acropora acuminata and its zooxanthellae. Mar.
