Spatial dynamics of benthic competition on coral reefs.

abstract：:Seasonal and nutritionally induced changes of whole body protein metabolism have been studied in 45 to 57 mm shell-length Mytilus edulis from Whitsand Bay, southwest England. The subtraction of measured net protein balances from coincident rates of protein synthesis, determined in vivo by supplying 15N-labelled alga a...
