Data associated with nutrient diffusing substrate experiments conducted in Lake Michigan and Lake Erie (2017)
Metals are used in primary producer metabolic pathways, such as photosynthesis and the acquisition of macronutrients nitrogen (N) and phosphorus (P), yet we often do not know their potential as limiting nutrients in freshwaters. In the Great Lakes, metals have sometimes been identified as limiting the acquisition of macronutrients, mostly in off-shore waters that are relatively isolated from tribu
Fatty acid tissue concentrations of laboratory fed Lampsilis cardium mussels
The role of disease in freshwater mussel declines has been largely ignored due to the lack of appropriate diagnostic tools and metabolomic markers of stress. Mussels in this study were either fed a prepared diet or unfed and their condition was assessed with the observed changes in fatty acid content of their tissue. This dataset contains quantitative fatty acid data from nonlethal (biopsy) sampli
Data from water column and sediment incubations from streams of Duck Creek and Fox River watersheds in Wisconsin, as well as the Fox rivermouth, the Saginaw rivermouth (Lake Huron, MI) and the Maumee rivermouth (Lake Erie, OH)
Nutrient reduction on the landscape scale often focuses on actions that reduce the movement of nitrogen (N) and phosphorus (P) from agricultural lands into streams and rivers. However, processing of N and P in streams and rivers can be substantial and increasing these in-stream processing rates could result in reductions or transformations of nutrients to less labile or less mobile forms. We hypot
Water column and sediment incubations to measure dissolved organic matter dynamics in the Fox rivermouth (Lake Michigan; 2016-2017)
These data are associated with experiments performed in 2016 and 2017 in the Fox rivermouth (Green Bay, WI; Lake Michigan). Between the De Pere Dam and the Lake Michigan coastline, we performed experiments to measure water column transformation of dissolved organic matter (DOM) and sediment flux of DOM. These experiments consisted of incubations of surface water or intact sediment cores and repeat
Response of natural phytoplankton communities from Green Bay (Lake Michigan) and Maumee Bay (Lake Erie) to laboratory manipulations of nutrient and trace metal availability during late summer 2018
Microcystins (MC) are a class of cyanotoxins produced by many cyanobacteria taxa. Although toxic to metazoans, the evolution of microcystin pre-dates the appearance of metazoans, and so MC did not originate as a toxin to potential metazoan grazers. One hypothesized functional role of microcystin is the management and acquisition of metals, several of which form complexes with MC intracellularly. M
Biofouling and mussel growth from mussels deployed in Great Lakes embayments (2013-2016)
Many taxa of North American unionid mussels are imperiled due to biofouling by invasive dreissenid mussels. Here, we report on biofouling rates of unionid mussels suspended in cages during the growing season in nearshore embayments in Lake Erie (2013-2016), Lake Michigan (Green Bay 2016, Grand Traverse Bay 2015) and Lake Huron (Saginaw Bay 2015). Mussels were deployed in early summer (late May or

These samples were collected as part of a study on spatial variation in ecosystem processes.

An assessment of N, P, Fe, Zn, Ni and Mo limitation on suspended nutrient diffusing substrates in nearshore areas of Lake Michigan and Lake Erie
In large lakes, metal availability sometimes limits the acquisition of nutrients (nitrogen, N and phosphorus, P) in offshore waters that are relatively isolated from tributaries and sediments. We hypothesize that metals may also be important within harmful algal blooms (HABs). HABs occur where nutrient loads are elevated, but bioassays often indicate that phytoplankton in HABs are N or P limited.

Comparison of sediment and water column nutrient processing rates in agricultural streams of contrasting buffer land use
Watershed nutrient management often focuses on actions that reduce the movement of nitrogen (N) and phosphorus (P) from agricultural lands into streams. One area of management focus is the buffer of land adjacent to streams. Wetlands and forests in this buffer can intercept and retain N and P from the landscape. In addition to directly intercepting agricultural nutrients, natural habitats in the b

Role of trace metal co-limitation in cyanobacterial blooms of Maumee Bay (Lake Erie) and Green Bay (Lake Michigan)
The open waters of large lakes can sometimes become so depleted in important metals that phytoplankton communities become either growth limited or limited in some metabolic function. Metals such as Fe, Ni, Mo, and Zn are used as co-factors for enzymes by phytoplankton in core metabolic functions, as well as metabolic pathways that allow phytoplankton to use less preferred forms of N and P (e.g. ni

Dissolved organic matter transformations in a freshwater rivermouth
River-to-lake transitional areas are biogeochemically active ecosystems that can alter the amount and composition of dissolved organic matter (DOM) as it moves through the aquatic continuum. However, few studies have directly measured carbon processing and assessed the carbon budget of freshwater rivermouths. We compiled measurements of dissolved organic carbon (DOC) and DOM in several water colum

Biofouling of a unionid mussel by dreissenid mussels in nearshore zones of the Great Lakes
In North America, native unionid mussels are imperiled due to factors such as habitat degradation, pollution, and invasive species. One of the most substantial threats is that posed by dreissenid mussels, which are invasive mussels that attach to hard substrates including unionid shells and can restrict movement and feeding of unionids. This dreissenid mussel biofouling of unionids varies spatiall

Corrigendum: Associations between cyanobacteria and indices of secondary production in the western basin of Lake Erie
In the last year, we became aware that data used in our above-referenced manuscript from 2018 published in Limnology and Oceanography contained significant errors. In the 2018 manuscript, we found that indices of secondary production were negatively correlated to indices of cyanobacterial abundance and toxicity. Unfortunately, one of our indices of cyanobacterial abundance (biovolume) and our meas

Water column nutrient processing rates in rivermouths of Green Bay (Lake Michigan)
Understanding the quantity and form of nutrient loads to large lakes is necessary to understand controls over primary production, phytoplankton community composition and the production of phytotoxins. Nutrient loading estimates to large lakes are primarily made at stream gages that are deliberately placed outside the direct influence of lake processes, but these estimates cannot take into account

Evaluating potential effects of bigheaded carps on fatty acid profiles of multiple trophic levels in large rivers of the Midwest, USA
Recent work indicates that the establishment of bigheaded carps (Hypophthalmichthys spp.) in the United States has led to a reduction in condition of native planktivores and may detrimentally affect other trophic levels by altering the base of aquatic food webs. We used fatty acids to evaluate potential effects of bigheaded carps on taxa from multiple trophic levels in the Upper Mississippi, Illin

Spatial and temporal variance in fatty acid and stable isotope signatures across trophic levels in large river systems
Fatty acid and stable isotope signatures allow researchers to better understand food webs, food sources, and trophic relationships. Research in marine and lentic systems has indicated that the variance of these biomarkers can exhibit substantial differences across spatial and temporal scales, but this type of analysis has not been completed for large river systems. Our objectives were to evaluate
