Lake Erie tributary nutrient trend evaluation: Normalizing concentrations and loads to reduce flow variability
Autor: Freya E. Rowland, Craig A. Stow, Laura T. Johnson, Robert M. Hirsch
Publikováno v: Ecological Indicators, Vol 125, Iss , Pp 107601- (2021)
Establishing tributary load (i.e., the mass exported over a period of time) targets to reduce anthropogenic nutrient inputs to receiving waters — and thus eutrophication — is a common mitigation strategy in freshwater and coastal ecosystems. Howe

Reducing phosphorus (P) concentrations in aquatic ecosystems, is necessary to improve water quality and reduce the occurrence of harmful cyanobacterial algal blooms. Managing P reduction requires information on the role rivers play in P transport fro

Despite the initial success of extensive efforts to reduce phosphorus (P) loading to Lake Erie as a part of the Great Lakes Water Quality Agreement, Lake Erie appears to be undergoing a re-eutrophication and it is plagued by harmful algal blooms. To

Needed: Early-term adjustments for Lake Erie phosphorus target loads to address western basin cyanobacterial blooms
Autor: Laura T. Johnson, Nathan Manning, Tian Guo, John P. Crumrine, Remegio Confesor, David B. Baker
Publikováno v: Journal of Great Lakes Research. 45:203-211
For Lake Erie, it is already time to revise the phosphorus target loads set to address the problem of cyanobacterial blooms in theWestern Basin. Current targets were proposed by the Annex 4 task group in 2015, adopted by U.S. and Canadian governments

Commentary: Achieving phosphorus reduction targets for Lake Erie
Autor: Laura T. Johnson, Jay F. Martin, Jeffrey M. Reutter, Kevin W. King, Robyn S. Wilson, Christopher Winslow, Kristen M. DeVanna Fussell, Gail Hesse, Gregory A. LaBarge, Margaret A. Beetstra

Harmful Algal Blooms (HABs), which were largely absent from Lake Erie from the 1980s until the mid-late 1990s, have been growing steadily worse in intensity. While much of the phosphorus loading into the lake prior to 1972 was caused by point-source

Publikováno v: Macintosh, K A, Doody, D G, Withers, P J A, McDowell, R W, Smith, D R, Johnson, L T, Bruulsema, T W, O’Flaherty, V & McGrath, J W 2019, ' Transforming soil phosphorus fertility management strategies to support the delivery of multiple ecosystem services from agricultural systems ', Science of the Total Environment, vol. 649, pp. 90-98 . https://doi.org/10.1016/j.scitotenv.2018.08.272
Despite greater emphasis on holistic phosphorus (P) management, current nutrient advice delivered at farm-scale still focuses almost exclusively on agricultural production. This limits our ability to address national and international strategies for

Tracking changes in nutrient delivery to western Lake Erie: Approaches to compensate for variability and trends in streamflow
Autor: Remegio Confesor, Anne F. Choquette, Robert M. Hirsch, Jennifer C. Murphy, Laura T. Johnson
Publikováno v: Journal of Great Lakes Research. 45:21-39
Tracking changes in stream nutrient inputs to Lake Erie over multidecadal time scales depends on the use of statistical methods that can remove the influence of year-to-year variability of streamflow but also explicitly consider the influence of long
