Causes and Consequences of a Collapsing Food Web in Lake huron
Lake Huron has undergone significant declines in abundance at multiple trophic levels. These declines are demonstrated to be the result of a decrease in the overall primary production, from an estimate of 100 g C m -2 yr-1 in the 1970s. to 32 g C m-2 yr -1 in this study. It is hypothesized that …

An Investigation Of The Soils Within And Beneath The Middens Of Two Huron Villages
Soils from within and beneath several Huron middens were investigated. Five types of material were identified within these structures and were tentatively labeled charcoal, midden matrix, subsoil, grey ash and white ash. Chemical analyses of samples taken from these layers enabled a computer …

Load reduction and invasive mussel effects on eutrophication dynamics in Saginaw Bay, Lake Huron
… phosphorus export to the main body of Lake Huron. The combined effects of increased phosphorus retention and decreased phosphorus loading have caused an ~60% decrease in phosphorus export from Saginaw Bay to Lake Huron. The analysis of long-term patterns of pelagic water quality highlights …
