Shell Convexity in Argopecten Gibbus: Variation with Depth in Harrington Sound, Bermuda
Abstract:Argopecten gibbus in Harrington Sound, Bermuda, is today confined to relatively shallow waters, but remains of an older population are found in the sediments of the deepest areas. Shell convexities differ markedly between the two populations, and transplant experiments indicate that members of the existing population will grow with the convexity characteristic of the defunct population while in deeper water, and with their normal convexity while in shallow water. Comparison of the hydrographic characteristics of Harrington Sound with the experimental observations suggests that turbulence is most likely to be the environmental variable directly affecting shell convexity.
