Calusa socioecological histories and zooarchaeological indicators of environmental change during the Little Ice Age in southwestern Florida, USA

The Pineland Site Complex, 8LL1902, is a large archaeological complex of middens, mounds, and other topographic features located in coastal, southwestern Florida. It was occupied from approximately AD 50 and was a major Calusa town at European contact. We combine extant research from this well-preserved site complex with new chronological and zooarchaeological analyses to provide new insight into the relationship between fisher-gatherer-hunter subsistence economies and small-scale but impactful climatic change. We identify and record the localized environmental changes co-occurrent with the global climatic episode known as the Little Ice Age (AD 1200–1850). By combining Bayesian statistical analyses of radiocarbon dates with zooarchaeological analyses of a waterlogged, shoreline midden we generate a high-resolution, localized view of socioecological interactions at the Pineland Site ca. AD 1200–1500. Such micro-scale temporal perspectives are necessary to achieve high resolution, localized histories of human-climate dynamics.
