| Abstract |
Year-round collection of hard clams (Mercenaria mercenaria and M. campechiensis) from 3 coastal sites in Florida permits documentation of the annual cycle of shell growth increment formation in these bivalves in the southern portion of their range. This cycle consists of alternating, macroscopic light increments (opaque white to beige) and dark increments (translucent grey to blue to purple) that are visible in the inner, middle, and outer shell layers of radially sectioned valves. |
