We employ social network analysis of collar decoration on Iroquoian vessels to conduct a multiscalar analysis of signaling practices among ancestral Huron-Wendat communities on the north shore of Lake Ontario. Our analysis focuses on the microscale of the West Duffins Creek community relocation sequence as well as the mesoscale, incorporating several populations to the west. The data demonstrate that network ties were stronger among populations in adjacent drainages as opposed to within drainage-specific sequences, providing evidence for west-to-east population movement, especially as conflict between Wendat and Haudenosaunee populations escalated in the sixteenth century. These results suggest that although coalescence may have initially involved the incorporation of peoples from microscale (local) networks, populations originating among wider mesoscale (subregional) networks contributed to later coalescent communities. These findings challenge previous models of village relocation and settlement aggregation that oversimplified these processes.

We describe six major stratigraphic units from the hitherto neglected Quaternary sequences along the north shore of Lake Ontario between Oshawa and Port Hope. These units, from the base upwards, consist of the following: a lowermost unit of silt till, apparently overlying bedrock; a complex unit of lacustrine and glaciofluvial sediments with several thin silt tills, usually unconformable on the lowermost unit; a glaciofluvial sand unit, filling valleys cut into the underlying units; a unit of two sandy pebbly tills; a silt till; and varved clays and sands of glacial Lake Iroquois.Though the sections show more erosional intervals, the above units can be correlated with the better known Scarborough sections as follows: the lowest unit with the Sunnybrook Till; the overlying complex unit with the Meadowcliffe Till and associated sediments; the two sandy pebbly tills with the lower Leaside Till; and the overlying silt till with the Halton Till.The inferred geological history is similar to that of the Scarborough area.

Abstract The results of a study to evaluate the suitability of a variety of microbiological, biochemical and bioassay tests to become part of a battery of test procedures to identify degraded or degrading water bodies, are presented. Data for this study were obtained from 51 inshore sampling sites along the north shore of Lake Ontario from Kingston to Niagara River. Data examination indicated that microbial population, biochemical or bioassay tests performed independently do not provide realistic estimates of priority concern areas and that the battery approach is required. From this study the sampling sites of highest concern were: Humber River STP out fall, mouth of Mimico Creek, mouth of Credit River and Bay of Quinte near the Belleville STP outfall.
