2010-2017 zooplankton data from whole water-column tows in Lakes Michigan and Huron
This data release includes zooplankton data collected from a collaborative effort for Environmental Protection Agency’s Cooperative Science and Monitoring Initiative (CSMI). Zooplankton surveys were conducted during the growing season, from late April to early November, in two Lake Michigan transects in 2010, two Lake Huron transects in 2012, eight Lake Michigan transects in 2015, and nine Lake Hu
Fish Egg Retention on Egg Mats in Experimental Flumes and Targeted Field Gear Egg Collection in the Detroit River, 2015-2016
Egg mat retention trials were conducted with walleye (Stizostedion vitreum) and lake whitefish (Coregonus clupeaformis) eggs in an experimental flume tank, seeded directly on egg mats (test retention efficiency) and hand dispersed in flowing flume water to simulate spawning over egg mats (test capture efficiency) with and without alternate substrate. In the field study, we measured number of eggs
Phytoplankton Community Composition in Western Lake Erie, 2014-2018; Grand Traverse Bay, Lake Michigan, 2015; and Saginaw Bay, Lake Huron, 2015
This dataset contains a tabular file of phytoplankton abundance and community composition analysis in samples collected from eight sites in the Western Lake Erie Basin; four sites in Grand Traverse Bay, Lake Michigan; and five sites in Saginaw Bay, Lake Huron. Samples were collected and processed by the Great Lakes Science Center of the U.S. Geological Survey (USGS) and analyzed by BSA Environment
Effects of fungal endophytes on invasive Phragmites australis (ssp. australis) performance in growth chamber and field experiments at the Indiana University Research and Teaching Preserve (N 39.217, W −86.540) (2018)
These data tables contain data collections from field experiments of Phragmites australis (ssp. australis) treated with known fungal endophytes. Tiller counts, tiller diameter, and tiller height measurements were taken every two weeks over an eight-week study period. Clones of Phragmites plants were collected from three different locations: Sandusky, Michigan; Bloomington, Indiana; and the Ottawa
Lake trout hatch rates using adults collected in 2019 from Northern Refuge, Lake Michigan
Data includes hatch, unfertilized, underdeveloped, and larval mortality count data of lake trout (Salvelinus namaycush) eggs fertilized from adult gametes collected within Northern Refuge reefs in Lake Michigan conducted by the U.S. Geological Survey Great Lakes Science Center during Fall 2019 gill net survey. Adult lake trout were collected using gill net (4.5, 5.5, and 6.0 inch) panels. Gametes
Reference genome for Phragmites australis (Poaceae, subfamily Arundinoideae) and comparison of North American invasive genotype (ssp. australis) and native (ssp. americanus)
These data represent the first reference genome for the invasive Phragmites australis ssp. australis (1.14 giga base pairs (Gbp)), as well as output from comparative genomic and transcriptomic analyses for invasive and native genotypes coexisting in the Great Lakes region of North America. Genome sequencing data used tillers and associated rhizome tissues collected from a single P. australis patch
Lake Erie Fish Community Data, 2013-2021
Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management, and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western basin of Lak
Pre-rehabilitation Biological Assessment of the Lower Maumee River, Ohio, 2019
Data are from biological and physical environmental assessments conducted during 2019 in the Maumee River, Ohio. Sites were located from river kilometer 24 to 11. Water quality parameters, fishes, invertebrates, and river channel characteristics were assessed during 2019 from May-September. Previously established standardized sampling methods were used during all assessments.
Data collected to support research on grass crop growth promotion and biostimulation by endophytic bacteria
These data show grass crop and model species response to toxic chemicals (Arsenic (As)) and humic acids. Experiments were performed by collaboration between the U.S. Geological Survey, Rutgers University, and Rey Juan Carlos University. A series of individual experiments investigated beneficial effects of endophytic bacteria on grass crop growth and resilience to known plant toxicity.
Zooplankton, Benthos, Mysis, and fish diet data from northern Lake Huron in 2012
These data consist of a multi-trophic, day vs. night, nearshore to offshore transect approach for data collection for this Cooperative Science and Monitoring Initiative effort at two northwestern Lake Huron sites near Hammond Bay and Thunder Bay, Michigan. Zooplankton and Mysis samples were collected monthly from April-October while benthos and prey fish samples were collected seasonally during Sp
Bottom dissolved oxygen measurements from Lake Erie's Central Basin, 2020
This data set, compiled by USGS Lake Erie Biological Station, provides near-bottom measurements of temperature and dissolved oxygen for the Central Basin of Lake Erie. Data were recorded by self-contained environmental data loggers (PME, Inc., MiniDOT data loggers). The data loggers were deployed during the stratified period (i.e., beginning of June 2020 through late October 2020) to better unders
Temperature and Depth Data from Walleye Archival Data Logging Tags in Lake Erie, 2014
While recording fish habitat use via electronic sensors, biologgers can also be viewed as autonomous environmental monitoring systems with the organism as a vehicle. This dual perspective has provided novel results from marine ecosystems but has not been applied to freshwater ecosystems. To understand limitations in freshwater, we evaluated miniature depth and temperature recorders, as aquatic mon
