Providing the scientific information needed by managers, decision makers, and the public to protect, enhance, and restore the ecosystems in the Upper Mississippi River Basin, the Midwest, and worldwide.
This Story Maps accompanies 4 peer-reviewed publications to provide a convenient and useful tool to access the information contained within these four peer-reviewed publications. The tree swallow data are easily visualized on a landscape scale, or more detail can be obtained by drilling down. These data are being used by States and EPA in their Beneficial Use Impairment (BUI) assessments.
The public is invited to attend a free, family-friendly open house at a local U.S. Geological Survey center for ecology research on Saturday, September 9.
Adding milkweeds and other native flowering plants into midwestern agricultural lands is key to restoring monarch butterflies, with milkweed sowers from all sectors of society being critically needed for success.
Annual variation in polychlorinated biphenyl (PCB) exposure in tree swallow (Tachycineta bicolor) eggs and nestlings at Great Lakes Restoration Initiative (GLRI) study sites
Tree swallow (Tachycineta bicolor) eggs and nestlings were collected from 16 sites across the Great Lakes to quantify normal annual variation in total polychlorinated biphenyl (PCB) exposure and to validate the sample size choice in earlier work. A sample size of five eggs or five nestlings per site was adequate to quantify exposure to PCBs in...Custer, Christine M.; Custer, Thomas W.; Dummer, Paul; Goldberg, Diana R.; Franson, J. Christian
Synthesis of tree swallow (Tachycineta bicolor) data for Beneficial Use Impairment (BUI) assessment at Wisconsin Areas of Concern
Assessment of the “Bird or Animal Deformities or Reproductive Problems” Beneficial Use Impairment (BUI) can be accomplished by (1) comparing tissue concentrations to established background and Lowest Observable Effect Level (LOEL) for reproductive effects, or (2) directly measuring reproductive success at Areas of Concern (AOCs) and statistically...Custer, Christine M.; Custer, Thomas W.; Dummer, Paul
Year-round presence of neonicotinoid insecticides in tributaries to the Great Lakes, USA
To better characterize the transport of neonicotinoid insecticides to the world's largest freshwater ecosystem, monthly samples (October 2015–September 2016) were collected from 10 major tributaries to the Great Lakes, USA. For the monthly tributary samples, neonicotinoids were detected in every month sampled and five of the six target...Hladik, Michelle; Corsi, Steven; Kolpin, Dana W.; Baldwin, Austin K.; Blackwell, Brett R.; Cavallin, Jenna E.
