Effects of population dispersal on regional signaling networks: An example from northern Iroquoia

Social network analyses show St. Lawrence Iroquoians as brokers between nascent Iroquois and Huron confederacies before A.D. 1500. The dispersal of Iroquoian groups from St. Lawrence River valley during the 15th and 16th centuries A.D. has been a source of archaeological inquiry for decades. Social network analysis presented here indicates that sites from Jefferson County, New York at the head of the St. Lawrence River controlled interactions within regional social signaling networks during the 15th century A.D. Measures indicate that Jefferson County sites were in brokerage liaison positions between sites in New York and Ontario. In the network for the subsequent century, to which no Jefferson County sites are assigned, no single group took the place of Jefferson County in controlling network flow. The dispersal of Jefferson County populations effectively ended this brokerage function concomitant with the emergence of the nascent Huron-Wendat and Iroquois confederacies and may have contributed to the escalation of conflict between these entities. These results add to a growing literature on the use of network analyses with archaeological data and contribute new insights into processes of population relocation and geopolitical realignment, as well as the role of borderlands and frontiers in nonstate societies.

Phytolith Evidence for the Early Presence of Maize in Southern Quebec

It has long been believed that maize (Zea mays spp. mays) was introduced in Quebec at around A.D. 1000, at the very beginning of the Late Woodland period. The identification and dating of maize phytoliths extracted from the carbonized encrustations on the interior surfaces of Native American ceramic vessels from three sites located in the St. Lawrence River valley, namely the Hector-Trudel, Station-4, and Place-Royale sites, indicate that this cultigen was rather introduced in that area during the Early Middle Woodland period, ca.400 to 200 B.C. These sites provide the northernmost and possibly the oldest evidence of maize consumption in northeastern North America. More samples of maize phytoliths from the same two sites were dated to the late Middle Woodland period, between A.D. 600 and 800, suggesting an increase in the ubiquity and importance of this new crop in the subsistence strategies. Moreover, the identification of an unknown variety of maize points toward the possibility that a new local variety of maize appeared during the process. This process might have been accompanied by a more intensive and complementary collecting of wild rice. Finally, the results support the hypothesis of an in situ origin of the St. Lawrence Iroquoians.
