Development of fluorescent staining method and effect of fluorescent staining on benthic invertebrate picking efficiency Development of fluorescent staining method and effect of fluorescent staining on benthic invertebrate picking efficiency
This is a tabular data set that includes intensity and saturation measurements of benthic invertebrates, sample residue, and preservative from samples stained with three fluorescent dyes for the development of a fluorescent staining method to enhance picking efficiency. This data set also contains data evaluating a selected fluorescent method's effects on picking efficiency and...

The data includes dates, places, and times of sampling events for eggs of invasive Grass Carp (Ctenopharyngodon idella) in tributaries to the Great Lakes in 2021 and 2022. Reference data on locations and dates sampled, gears used, and effort are included. Developmental stages for a subset of undamaged, fertilized eggs are provided. Tables include common fields to allow for integration...
Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Upper Peninsula, U.S.: Degree Flowlines Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Upper Peninsula, U.S.: Degree Flowlines
This dataset is part of the U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative. These data represent the flowline network in the Upper Peninsula Restoration Assessment (UPRA). 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...
Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Upper Peninsula, U.S. Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Upper Peninsula, U.S.
This dataset contains all the layers associated with U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative for the Upper Peninsula Restoration Assessment (UPRA) which aims to identify and rank coastal areas with the greatest potential for wetland habitat restoration. Each layer has a unique contribution to the identification of restorable...
Upper Peninsula Coastal Wetland Restoration Assessment: Dikes Upper Peninsula Coastal Wetland Restoration Assessment: Dikes
This dataset is part of the U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative. These data represent the location of dikes within the Upper Peninsula Restoration Assessment (UPRA) study area. An ArcGIS model (Python script) identified dikes as having a difference in elevation above a certain threshold. If the elevation difference was...
Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Green Bay, U.S.: Degree Flowlines Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) Green Bay, U.S.: Degree Flowlines
This dataset is part of the U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative. 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...

This dataset contains all the layers associated with U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative for the Green Bay Restoration Assessment (GBRA) which aims to identify and rank coastal areas with the greatest potential for wetland habitat restoration. Each layer has a unique contribution to the identification of restorable wetlands...

Effects of warming on development rates on Karner Blue Butterfly laboratory data (2011-2012) Effects of warming on development rates on Karner Blue Butterfly laboratory data (2011-2012)
The dataset is associated with a project that examines effects of climate change on the federally endangered Karner blue butterfly (Lycaeides melissa samuelis) by subjecting different life stages of the Karner blue to both historically average temperature regimes and temperature regimes 2, 4, and 6 degrees Celsius above historic means. This dataset is composed of two spreadsheets: one...
Genotype Data for Eastern Massasauga Rattlesnakes (Sistrurus catenatus) from Bois Blanc Island, Michigan at 15 Microsatellite DNA Loci Genotype Data for Eastern Massasauga Rattlesnakes (Sistrurus catenatus) from Bois Blanc Island, Michigan at 15 Microsatellite DNA Loci
We investigated fine-scale genetic patterns of the federally threatened Eastern Massasauga Rattlesnake (Sistrurus catenatus) on a relatively undisturbed island in northern Michigan, USA. This species often persists in habitat islands throughout much of its distribution due to extensive habitat loss and distance-limited dispersal. These data are from 102 individual Eastern Massasauga...
Larval lake whitefish diets in western Lake Erie during 2018, 2019, and 2021 Larval lake whitefish diets in western Lake Erie during 2018, 2019, and 2021
Recent declines in Lake Whitefish population abundance has prompted research to identify underlying mechanisms controlling survival of early life stages in the Great Lakes. In Lake Erie, the recruitment bottleneck window determining year class strength of Lake Whitefish occurs during the first growing season, suggesting that availability of prey could be controlling year class strength...
Literature Review of Lithophilic-Spawning Fishes Egg Collection Methods Literature Review of Lithophilic-Spawning Fishes Egg Collection Methods
Assessment of egg deposition is widely used to provide an index of spawning efforts for lithophilic-spawning fishes. However, little is known about the collection techniques efficacy and bias when collecting fish eggs. We conducted a literature review to assess egg collection methods and evaluate egg retention and capture on egg mats. The literature review provided a summary of different...
