Laboratory experiments conducted on the multichambered planktic foraminifera Globigerinoides sacculifer are used to determine the effect of symbiont photosynthesis on shell carbon and oxygen isotopic composition. Stable isotope analyses of individual chambers secreted under controlled temperature and light levels show that chamber jl3C values increase with increasing light levels. The effect of ontogeny on chamber J ~3C is minimal in the size range 350 to 850/tm. Shell size: Jt3C covariance in… CONTINUE READING
