The Jupiter Inlet I site is situated between the Atlantic coast and the Loxahatchee River in southeast Florida. Although excavations were previously conducted, faunal remains were not systematically collected until recently. Molluscan remains recovered in 2010 are examined to reconstruct past ecological habitats, identify which water bodies were used for extracting resources, and document changes in molluscan species over time. Based upon identifications, only brackish and marine species are represented, indicating that the Loxahatchee River was brackish rather than freshwater during the time of occupation and that the site inhabitants were collecting mollusks from both the lagoon and coastal waters. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
