Intensification revisited: assessing resource specialization at Crystal River (8CI1) and Roberts Island (8CI41), Florida

Archaeologists typically associate resource intensification with population expansion, environmental change, and political strategizing. Many Late Woodland and Mississippian societies of the Southeast eschewed dietary diversity in favor of harvesting fewer types of resources that could meet the subsistence demands of incipient aggregation. Foods such as maize and shellfish can provide humans with predictable caloric yields and are amenable to control by individuals or corporate groups. However, some archaeologists have identified scenarios in which small-scale societies intensified resources in the absence of population growth and social inequality. Ritual economies can periodically place high demands on the materials used for gatherings and ceremonies. These events then may leave material residues of economic intensification, which archaeologists might easily mistake as evidence for population expansion or social evolution. We use diversity and equitability estimates of zooarchaeological deposits from Crystal River (8CI1) and Roberts Island (8CI41), Florida, to demonstrate that some Woodland period societies periodically intensified their use of resources amidst population decline and heightened ritual activity. We suggest that the inhabitants of the area harvested shellfish at increasingly high rates to provide the material basis for a series of ritual interventions that aimed to circumvent the effects of rapid social and ecological change.
