Zooxanthallae can adapt to different temperatures

By on

We know corals are able to cope with changing temperatures when they host a mix of zooxanthellae clades (types), favoring one clade over another depending on environmental conditions. But AIMS researchers have now discovered the symbiotic algae themselves can adapt to different temperatures.

Aquarium Corals: Applying PAM fluorometry for the advancement of coral aquaculture

By Zack Zartler on Jan 18, 2012 at 10:00 AM

(Alaska Pacific University) While the aquaculture of corals has greatly improved with recent technological advances in water parameter regulation, flow control, and lighting, a lag persists in physiological examination of the health of coral specimens. A cost-friendly, pulse amplitude modulated (PAM) fluorometer (Junior- or JR-PAM) was used to examine photosynthetic activity of corals within recommended aqua-culturing temperature ranges. A total of 24 coral fragments were used, representing four species: Acropora sp., Montipora digitata, Pavona decussatus, and Seriatopora hystrix. Exposure to typical, aqua-culturing temperature treatments (22, 24, 26, and 28°C) for three week periods revealed significant restrictions of photosynthesis at lower- and higher-end temperatures. Both maximum quantum yield (FV/FM) and maximum, relative electron transport rate (rETR) were significantly different across the four-interval temperature range. The efficacy of the JR-PAM for in situ coral research was also examined, and usefulness for determining coral productivity was assessed.
