Mycorrhizal colonization across hydrologic gradients in restored and reference freshwater wetlands
Arbuscular mycorrhizae, which are plant root-fungal symbioses, are common associates of vascular plants. Such relationships, however, are thought to be rare in wetland plant roots, although several recent stud...

Landscape predictors of stream dissolved organic matter concentration and physicochemistry in a Lake Superior river watershed
We examined landscape predictors of dissolved organic matter (DOM) concentration, molecular weight (Mw), and molar absorptivity at 280 nm (ɛ280) in 60 streams from the Ontonagon River watershed in northern Michig...

Scale-dependent influences on water quality, habitat, and fish communities in streams of the Kalamazoo River Basin, Michigan (USA)
In 2002, we investigated regional versus local influences of 22 streams in the Kalamazoo River basin, MI (USA) to: 1) determine how stream water quality, habitat, and fish communities were influenced by enviro...

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...

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,...

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...

Article
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 ...

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...

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 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...

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...
