摘要

The natural radiocarbon (~(14)C) content of whole, gut voided Saccoglossus bromophenolosus collected in Lowes Cove, Maine, USA, was compared with that of a non-voided worm, sectioned individuals, and the natural product 2,4-dibromophenol (2,4-DBP) isolated from S. bromophenolosus. In all cases, the ~(14)C content was greater than that of the sediment from which the enteropneusts were collected. The ~(14)C content of 2 polychaetes, Glycera dibranchiata and Clymenella torquata, also collected from Lowes Cove, were similarly enriched in ~(14)C compared to the bulk sediment. These results show that all 3 species consumed recently fixed carbon that was much newer than organic carbon in the bulk sediment. The value (+10.4 per thousand) obtained for 2,4-DBP isolated from S. bromophenolosus in this study differs from that reported in a previous study (-170 per thousand). The discrepancy is attributed to methodological differences. The importance of selecting an appropriate method when isolating compounds for natural abundance ~(14)C analysis is discussed.
