Simulated changes in extent of Georgian Bay low-marsh habitat under multiple lake levels
The extent of coastal wetlands in Georgian Bay is controlled primarily by water level of Lake Huron, which directly affects the amount of critical habitat available for fish and wildlife communities. Lake-levels have historically fluctuated by nearly 2 m and that range could… Read More
Development of a multi-scale wetland Resilience Index from muskellunge nursery habitat in Georgian Bay, Lake Huron
In a 2012 study, no age-0 muskellunge (Esox masquinongy) were found in any of 16 historic nursery sites in coastal marshes of southeastern Georgian Bay (SEGB), and this was attributed to sustained low water levels (1999–2013) that had altered the vegetation structure of nursery… Read More
Models to predict total phosphorus concentrations in coastal embayments of eastern Georgian Bay, Lake Huron
Several coastal embayments of eastern Georgian Bay show signs of water-quality impairment thought to be caused by human activities. Here, we evaluate the ability of the Lakeshore Capacity Model (LCM), developed for Precambrian Shield lakes,to assess the impact of cottage… Read More
Threats to aquatic habitat in coastal marshes of Georgian Bay: climate change, invasive species and human impacts
Of the key ecosystem services provided by wetlands, one of the
most important is the provision of habitat for numerous fish,
birds, and wildlife species. Nowhere is this more important
than in the thousands of pristine coastal marshes lining the
shoreline of eastern Georgian … Read More
Spawning season distribution in sub-populations of Muskellunge in Georgian Bay
Loss of spawning and nursery habitat has been implicated as a major factor in the widespread decline of Muskellunge Esox masquinongy populations in N. America. Although there is limited evidence of spawning-site fidelity in the Great Lakes populations of Muskellunge, such… Read More
