EVIDENCE FOR HETEROTROPHY BY ZOOXANTHELLAE IN SYMBIOSIS WITHAIPTASIA PULCHELLA

open access: yesThe Biological Bulletin, 1986
Sea anemones (Aiptasia pulchella) fed 35S methionine labeled food translocated labeled material to symbiotic zooxanthellae. This uptake of host-derived organic materials by the symbiotic algae is interpreted as evidence for heterotrophy. It is calculated that 2.8-6.4% of the zooxanthellae growth requirement for protein was satisfied by heterotrophy ...

Effects of heterotrophy on the physiological responses of the scleractinian coral Goniopora lobata in Hong Kong.

open access: yes, 2012
石珊瑚是具有自營及異營功能的生物,近年來,異營功能被認為是石珊瑚很重要的營養來源,可令牠們從珊瑚白化中復原。香港每年的海水溫度可由冬天的攝氏十三度升到夏天的三十度,這季節性的溫度變異令香港成為石珊瑚生存的邊緣地方,石珊瑚只能組成群落但不能成礁。雖然環境因素對於石珊瑚的生長並不理想,但大型的珊瑚白化仍沒有發生,這意味著香港的珊瑚比較能夠適應香港的嚴峻困難環境,珊瑚具有的異營功能或許能夠提供牠們額外的能量,作為日常新陳代謝之用。所以,這研究的目標是找出異營功能對香港石珊瑚的重要性,這研究以豐年蝦的無節幼體 ...

Global net community production and the putative net heterotrophy of the oligotrophic oceans

open access: yes
Reconciling rates of organic carbon export from the euphotic zone with the consumption of organic material in the dark ocean remains one of the major quantitative uncertainties of the ocean carbon cycle.
