GCE - Mollusc pop. size dist. Mon.: Spring 2002 mid-mrsh and creekbnk infaunal and epifaunal mollusc size dist. based on collect. from GCE mrsh, mon. sites 1-10

Infaunal and epifaunal molluscs were hand-collected from within quadrats of known area from mid-marsh and creekbank zones (n = 4 quadrats per zone) at all sites. The molluscs were returned to the lab, fixed in formalin, transferred to and preserved in ethanol, measured and counted (count data is reported separately).

Length of each measurable individual was determined using calipers or small etched rulers under a stereomicroscope. Species abundance and density data for these collections may be found in the GCE-LTER data set INV-GCEM-0412a1. Numbers of individuals of each species in the abundance data file may not correspond exactly to the numbers of individuals in the size data file because some individuals may not have been measureable.
