Isotopic evidence of particle size-dependent food partitioning in cocultured sea squirt Halocynthia roretzi and Pacific oyster Crassostrea gigas
To examine the trophic relationship between the sea squirt Halocynthia roretzi and the Pacific oyster Crassostrea gigas cocultured in suspension, their delta C-13 and delta N-15 values were monitored monthly on the southern coast of Korea for a period of 2 yr. Suspended particulate organic matter wa...
