Synergistic impact of water level fluctuation and invasion of Glyceria on Typha in a freshwater marsh of Lake Ontario
The effects of multiple stressors on the native Typha marsh community (mainly Typha latifolia) were examined using historical records of water levels, human census population, and field vegetation maps. Percent cover of the major plant species was estimated in a GIS, and the… Read More
Development and validation of the Wetland Fish Index to assess the quality of coastal wetlands in the Laurentian Great Lakes
We use fish and environmental data from 40 wetlands of the Laurentian Great Lakes to develop the Wetland Fish Index (WFI), a tool that can be used to assess the quality of coastal marshes. A partial canonical correspondence analysis was used to ordinate fish species along… Read More
Development of the Water Quality Index (WQI) to assess effects of basin-wide land-use alteration on coastal marshes of the Laurentian Great Lakes
Water-quality impairment for many coastal wetlands of the lower Great Lakes has been attributed to nutrient and sediment inputs from agricultural and urban landscapes, although for some marshes, point-source pollution from municipal or industrial waste- treatment facilities and… Read More
Influence of shoreline features on fish distribution in the Laurentian Great Lakes
In this paper, we used assembled fish distributions (over 9500 field observations) and correlated them with 11 categories of the Great Lakes shoreline (i.e., bedrock, bluff, coarse beach, sandy beach – dune, sandy–silty bank, clay bank, low riverine – coastal plain,… Read More
