GCE-LTER Data Set Summary

Accession: INV-GCES-0706b Research Theme: Aquatic Invertebrate Ecology (Directed Study)

Title: Summer 2007 mollusc population survey in fifty-five GCE LTER Hammock sites and five GCE marsh monitoring sites
Abstract: Mollusc species and abundance was determined within fifty-five GCE LTER hammock sites and five GCE LTER study sites in June-July 2007. Species abundance was determined by hand-collecting all molluscs from within quadrats of known area at six plots at each site. Molluscs were brought back to the lab, preserved in ethanol, then counted and measured (size data is reported separately).
