Data

This dataset represents data collected during field trials testing a novel bioherbicide solution on the invasive wetland plant Phragmites australis in the summer of 2022. The bioherbicide solution composed of naturally derived ingredients (arginine, sucrose, citrus oil, and water) is intended to target microbial communities associated with Phragmites to induce stress and reduce the...

This data release includes thiamine concentration measurements from lake trout (Salvelinus namaycush) eggs and associated biological data (e.g., fish length, weight, sex) and capture location data (e.g., lake, coordinates, date of collection). Lake trout used in this dataset were collected during 2025 from across the Great Lakes and other inland lakes such as the Finger Lakes, New York...

This data release contains three datasets for the Pitcher's thistle (Cirsium pitcheri) reintroduction experiment, started in 1994, at the Portage Lakefront unit (formerly called Ogden Dunes), Indiana Dunes National Park, Porter County, Indiana. This plant species is a Federally threatened monocarpic perennial plant endemic to the sand dunes of the western Great Lakes. There are three csv...

The data records DNA barcode sequences and species level identifications of fungi and bacteria that were isolated from Phragmites australis leaves collected in along the east coast of North America. These samples were collected in 2015 from populations of native and non-native Phragmites by collaborators at Louisiana State University from plants that were visibly diseased and visibly...

Annual spring (May) and fall (late October through early November) gillnet assessment surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in northern Lake Michigan, including the Northern Refuge, between 1998-2025. Total length, weight, sex, maturity, and sea lamprey wounds were recorded for each lake trout and burbot caught in the gill nets. Lake trout...

Acoustic telemetry is a popular tool for the study of fish spatial ecology. In acoustic telemetry, fish are captured, surgically implanted with an acoustic transmitter or ‘tag’, and then released back into the environment. Networks of autonomous, stationary receivers then are used to track the movements of tagged individuals over long periods of time (> 1 year). Each acoustic receiver...

Cisco and Bloater growth data from hatchery reared fish were collected in association with a project to repopulate Lake Ontario native prey species. Fish were grown and measured under hatchery conditions for up to nine months before being released into Lake Ontario. Weekly measurements of total length, total weight, and morphometrics were recorded for both species to determine growth...

This dataset records Cladophora and associated benthic algae, collectively Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2022 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting data...

In June 2017, Lake Sturgeon were observed spawning in Fall Creek, a tributary to Cayuga Lake, NY. The spawning site was just downstream of Ithaca Falls, the first impassible barrier. Data were collected to quantify the stream habitat use by the Lake Sturgeon. These were the first sturgeon observed spawning in a Cayuga Lake tributary recorded in the New York Department of Environmental...

Individual point estimates of stream density by juvenile salmonid species in two small tributaries to the Salmon River, Lake Ontario, New York were recorded. Enumeration of salmonid species was observed using a backpack electrofisher in order to identify fish species. Stream density estimates were calculated using stream width measurements taken at equally spaced transects. Comparisons...

These data consist of prey fish density and biomass estimates throughout Lake Michigan during late summer-fall from 1973 to 2025 along with alewife (Alosa pseudoharengus) recent age estimates collected. Fish were collected using bottom or midwater trawls. In addition to fish data, some zebra and quagga mussel (Dreissena spp.) biomass estimates are included as well as recent native...

In association with a project to estimate stream habitat use by two fish species; habitat parameters where slimy sculpin and rainbow trout were captured were recorded. Habitat use was observed using a backpack electrofisher in order to determine where fish were residing. Total stream habitat was calculated using equally spaced transects with observational recording of stream water depth...
