Calcification of Filaments of Boring and Cavity-Dwelling Algae, and the Construction of Micrite Enviment grains in reef environments. The activities of endolithic algae affect or control particle angularity and size, sediment porosity and permeability, particle micritization, micrite envelope formation, and other aspects of carbonate erosion and diagenesis..In controlled experiments in the shallo

An Agricultural Revolution in the Lower Great Lakes,roquoian Princess Point Complex of southwestern Ontario. However, subsequent research has revealed earlier evidence of plant husbandry by proto-Iroquoian peoples in northwestern Ohio and southeastern Michigan, who represent the late Middle Woodland to early Late Woodland of the Western Basin Traditi

The Return of Aquatic Vascular Plants into the Great Lakes Region after Late-Wisconsin Glaciation,despread genera, . and . were chosen because they are most frequently recorded in pollen diagrams. The movements of these genera were inferred by obtaining published pollen diagrams in which these genera were recorded. Only those records were used which were radiocarbon dated or based on inferences

Migration routes were influenced by both physiographic (Appalachians, Great Lakes) and climatic factors. The spread of . and . to their present ranges in glaciated areas is re-examined; additional detailed radiocarbon-dated analyses are req
