“…The differences in elevation along the sandspit also contribute to a mosaic of habitats with ponds, meadows, and marshes occurring throughout Long Point (Reznicek and Catling, 1989). Many of these vegetation zones are important for maintaining plant diversity and abundance as Long Point supports rare coastal marsh meadow habitat and a number of provincially rare plant species, many of which are wetland or aquatic species (Ball et al, 2003;Prince et al, 1992;Reznicek and Catling, 1989).…”

“…Located on the Atlantic flyway, the abundant submerged aquatic vegetation and protected waters of the bay and marsh complexes make Long Point a waterfowl staging area of international importance (Knapton and Petrie, 1999;Prince et al, 1992 (Ball et al, 2003). The regional and international importance of Long Point has been recognized through designations as a UNESCO World Biosphere Reserve, a RAMSAR wetland of international significance, and an Important Bird Area.…”

“…Habitat structure is also one of the most important factors determining use by waterbirds (see reviews by McNicholl 1985 andPrince et al 1992), Suitability of nesting habitat for many waterbirds of the Great Lakes is enhanced by disturbance that reduces density of wetland vegetation. Openings, if colonized by submersed vegetation, are ideally suited to waterfowl (Bookhout et al 1989).…”

Hydrogeomorphic factors and ecosystem responses in coastal wetlands of the Great Lakes

Gauging the impact of manipulative activities, such as rehabilitation or management, on wetlands requires having a notion of the unmanipulated condition as a reference. An understanding of the reference condition requires knowledge of dominant factors influencing ecosystem processes and biological communities. In this paper, we focus on natural physical factors (conditions and processes) that drive coastal wetland ecosystems of the Laurentian Great Lakes. Great Lakes coastal wetlands develop under conditions of largelake hydrology and disturbance imposed at a hierarchy of spatial and temporal scales and contain biotic communities adapted to unstable and unpredictable conditions. Coastal wetlands are configured along a continuum of hydrogeomorphic types: open coastal wetlands, drowned river mouth and flooded delta wetlands, and protected wetlands each developing distinct ecosystem properties and biotic communities. Hydrogeomorphic factors associated with the lake and watershed operate at a hierarchy of scales: a) local and short-term (seiches and ice action), b) watershed / lakewide / annual (seasonal water-level change), and c) larger or year-to-year and longer (regional and/or greater than one-year). Other physical factors include the unique water quality features of each lake. The aim of this paper is to provide scientists and managers with a framework for considering regional and site-specific geomorphometry and a hierarchy of physical processes in planning management and conservation projects_

Abstract. Zebra mussels (Dreissena polymorpha) are an important component of benthic communities in the Great Lakes and are exploited by a host of predators, including waterfowl. In this study, we analyze diet content and stable isotope and organochlorine contaminant patterns in Lesser Scaup (Aythya affinis), Greater Scaup (Aythya marila), Bufflehead (Bucephala albeola), Redhead (Aythya americana), Canvasback (Aythya valisineria), and Mallard (Anas platyrhynchos) collected from three sites (Fighting Island, western Lake Erie, Big Creek) in the lower Great Lakes. Lesser and Greater Scaup from Fighting Island were classified as either zebra mussel (Ն67% of diet) or macrophyte (Ն85% of diet) consumers. Bufflehead, Canvasback, Mallard, and Redhead consumed mainly (Ն89%) macrophyte at Fighting Island. Zebra mussel was the principal food of Lesser Scaup (Ͼ99%), Greater Scaup (97%), and Bufflehead (72%) in western Lake Erie. Stable isotope analysis revealed enrichment of ␦ 15 N in Lesser Scaup (Ն2.24‰), Greater Scaup (Ն1.28‰), and Bufflehead (Ն0.63‰) that exploited mussels relative to conspecifics with macrophyte diets and relative to mussel prey.Representative contaminants of low (hexachlorobenzene [HCB]), moderate (PCB [polychlorinated biphenyl] 153), and high (PCB 180) hydrophobicity were examined in waterfowl. Lipid-normalized concentrations of PCBs 153 and 180 were significantly higher in scaup and Bufflehead that consumed Dreissena than in individuals that ate mainly macrophytes. Among taxa that consumed primarily Dreissena, concentrations of PCBs 153 and 180 were significantly higher in individuals from Lake Erie than in those Fighting Island. Principal components analysis revealed broad differences in contaminant patterns of waterfowl based principally on diet.Results from this study illustrate that Dreissena has become a primary food source of some waterfowl in the lower Great Lakes and serves as an effective conduit for transfer of persistent organic contaminants to higher trophic levels.
