Bioaccumulation of mercury in Lake Michigan painted turtles (Chrysemys picta)
Mercury (Hg) contamination of aquatic environments can lead to bioaccumulation in organisms, but most previous work has focused on fish and not on semi-aquatic reptiles such as turtles that traverse both terre...

Identifying human health risks from precious metal mining in Sierra Leone
Water pollution results in more than two million human deaths every year, with a disproportionate amount of mortality occurring in develo** countries. Tracing how and where water-borne pollutants enter the h...

Beyond nitrogen and phosphorus subsidies: Pacific salmon (Oncorhynchus spp.) as potential vectors of micronutrients
Large quantities of material are moved annually from the ocean to freshwater systems by migrating Pacific salmon. Previous studies have focused on nitrogen and phosphorus provided by spawning salmon but largel...

Open AccessLeveraging a Landscape-Level Monitoring and Assessment Program for Develo** Resilient Shorelines throughout the Laurentian Great Lakes
Traditionally, ecosystem monitoring, conservation, and restoration have been conducted in a piecemeal manner at the local scale without regional landscape context. However, scientifically driven conservation a...

Methane Cycling Contributes to Distinct Patterns in Carbon Stable Isotopes of Wetland Detritus
Increasing global temperatures are changing the balance between carbon sequestration and its microbial processing in wetlands, making the tracking of these processes important. We used detrital carbon stable i...

Open AccessAn expanded fish-based index of biotic integrity for Great Lakes coastal wetlands
Biotic indicators are useful for assessing ecosystem health because the structure of resident communities generally reflects abiotic conditions integrated over time. We used fish data collected over 5 years fo...

Open AccessStandardized Measures of Coastal Wetland Condition: Implementation at a Laurentian Great Lakes Basin-Wide Scale
Since European settlement, over 50 % of coastal wetlands have been lost in the Laurentian Great Lakes basin, causing growing concern and increased monitoring by government agencies. For over a decade, monitori...

Open AccessMolecular mechanisms of ionic liquid cytotoxicity probed by an integrated experimental and computational approach
Ionic liquids (ILs) are salts that remain liquid down to low temperatures and sometimes well below room temperature. ILs have been called “green solvents” because of their extraordinarily low vapor pressure an...

Body burdens of heavy metals in Lake Michigan wetland turtles
Tissue heavy metal concentrations in painted (Chrysemys picta) and snap** (Chelydra serpentina) turtles from Lake Michigan coastal wetlands were analyzed to determine (1) whether turtles accumulated heavy metal...

Freshwater hotspots of biological invasion are a function of species–pathway interactions
The introduction and spread of aquatic invasive species constitutes a global epidemic that continues to homogenize the world’s aquatic flora and fauna. Species invasions are occurring at an unprecedented scale...

Habitat influences Pacific salmon (Oncorhynchus spp.) tissue decomposition in riparian and stream ecosystems
Decomposition incorporates organic material delivered by Pacific salmon (Oncorhynchus spp.) into aquatic and terrestrial ecosystems of streams where salmon spawn. We hypothesized that salmon tissue decomposition ...

Biogeochemical transformation of a nutrient subsidy: salmon, streams, and nitrification
Migratory animals can alter ecosystem function via the provision of nutrient subsidies. These subsidies are heterogeneous in space and time, which may create hot spots or hot moments in biogeochemical transfor...

Whole-Stream Metabolism Responds to Spawning Pacific Salmon in Their Native and Introduced Ranges
Pacific salmon (Oncorhynchus spp.) perform important ecological roles in stream ecosystems by provisioning nutrients as resource subsidies and modifying their physical habitat as ecosystem engineers. These contra...

Ecological Effects of Live Salmon Exceed Those of Carcasses During an Annual Spawning Migration
We tested the hypothesis that the carcasses of anadromous Pacific salmon (Oncorhynchus spp.) constitute a significant source of nutrients in the nutrient-poor freshwaters where these fish migrate, spawn, senesce,...

Do non-native earthworms in Southeast Alaska use streams as invasional corridors in watersheds harvested for timber?
Exotic earthworms from Europe and Asia have invaded previously earthworm-free areas of North America where they consume leaf litter, mix soil horizons, and alter nutrient cycling. Primarily, earthworm introduc...

Pacific salmon effects on stream ecosystems: a quantitative synthesis
Pacific salmon (Oncorhynchus spp.) disturb sediments and fertilize streams with marine-derived nutrients during their annual spawning runs, leading researchers to classify these fish as ecosystem engineers and pr...

Non-native earthworms in riparian soils increase nitrogen flux into adjacent aquatic ecosystems
Riparian zones are an important transition between terrestrial and aquatic ecosystems, and they function in nutrient cycling and removal. Non-native earthworms invading earthworm-free areas of North America ca...

Effects of spawning salmon on dissolved nutrients and epilithon in coupled stream-estuary systems of southeastern Alaska
Spawning migrations of Pacific salmon (Oncorhynchus spp.) represent a significant nutrient pulse to freshwater ecosystems of southeastern Alaska. These salmon-derived nutrients (SDN) can be transported by streamf...

Predicting habitat use and trophic interactions of Eurasian ruffe, round gobies, and zebra mussels in nearshore areas of the Great Lakes
The Laurentian Great Lakes have been subject to numerous introductions of nonindigenous species, including two recent benthic fish invaders, Eurasian ruffe (Gymnocephalus cernuus) and round gobies (Neogobius mela...
