Hydrogeochemical Mixing data from Lake Michigan Tributaries 2011 This dataset describes the hydrogeomorphic structure and lake-tributary mixing in three intermediate-sized Lake Michigan rivermouths: Ford River, Manitowoc River, and Pere Marquette River. Data were collected from May to October 2011. Water chemistry variables were measured with a multiparameter sonde along longitudinal, lateral, and vertical transects. Magnesium, boron, and stable water isotope concentrations were also determined from grab water samples at particular depths.

These data represent the flowline network in the Green Bay Restoration Assessment (GBRA). It is attributed with the number of disconnections (e.g., road crossings) between the reach and Lake Ontario. The more road crossings on a flowline the more disconnected that area is from the lake and the less suitable it will be for restoration. These data help identify the condition of hydrologic separation between potential restoration areas and Lake Ontario. Low numbers represent fewer disconnections, such as culverts, between the reach and the water body requiring no flow network modification...

Management units were located in Michigan, Ohio, and Wisconsin (USA). Invasive Phragmites australis (hereafter "Phragmites") had been managed at each management units some time previously by the landowner or land manager, and aerial imagery was then collected to create cover classifications distinguishing live and dead Phragmites from the surrounding landscape using object-based image analysis with training based on ground-truth...

Clones of Phragmites plants were collected from three different locations: Sandusky, Michigan; Bloomington, Indiana; and the Ottawa National Wildlife Refuge near Oak Harbor, Ohio. Additionally, data collections from a similar experiment of Phragmites australis (ssp. australis) treated with known fungal endophytes performed in a growth chamber are included.

We propagated these field-collected samples to carry out a reciprocal-transplant plant-soil feedback experiment with multiple microbial inhibition treatments. Specifically, we investigated how each Phragmites lineage grew in soils pre-conditioned by each lineage and soils that had been pre-sterilized. Plant biomass was the main response variable collected to determine responses to microbial soil conditioning. We also used DNA meta-barcoding to identify...

However, this ability has largely been neutralized as vast areas of coastal wetlands have been isolated behind dikes; while at the same time the Great Lakes continue to suffer from excess phosphorus loading. In this study we used high-frequency measurements of discharge and turbidity to estimate sediment and phosphorus retention in a formerly diked coastal wetland. We found sediment and phosphorus retention to be episodic and highly related to fluctuations in water level. Low water levels in Lake Erie in late 2012 resulted in low retention in the wetland, but...

The North and South management units of the Maankiki Marsh Complex were reconnected to the Shiawassee River in 2018, whereas Pool 1A represents a historically reconnected wetland. Additional sites within the Shiawassee River and Spaulding Drain (east of Pool 1A) were also sampled to represent parameters collected from the parent water system. All data were collected in 2019.

Vegetation quadrat data provide percent cover estimates per sampling quadrat and overall mean percent cover (MPC) values per species by vegetation type from 1994, and 1996-2010. Vegetation mapping (a.k.a., "photointerpretation") geospatial datasets provide full site cover visualizations and feature class information by vegetation type from 1994,1996-2002, and 2022.

One-hour-long video data files were used to estimate fish activity in a restored coastal wetland within Ottawa National Wildlife Refuge in the Western Basin of Lake Erie. Over 800 video hours of fish movement were recorded at the fully open fish passage structure; 136 video data files were chosen at random to represent the full video data file set and are available upon request.

Genome sequencing data used tillers and associated rhizome tissues collected from a single P. australis patch at the Ottawa National Wildlife Refuge near Toledo, Ohio, USA.

Leaf and bract cells of more than 30 species in 18 families of seed plants were surveyed for the presence of intracellular bacteria and several experiments were designed to find and analyze nutrient exchanges between bacteria and plant cells. This dataset contains the results of 1) histochemical analyses to detect hormones, superoxide, and nitrogenous chemicals around bacteria within plant leaf and bract cells, 2) experiments to assess the differential absorption of isotopic nitrogen into plants, and 3) genetic analysis of bacteria isolated from plant material.
