Melinda Martinez, Robert Bordelon, Beth A. Middleton, Jorge A. Villa, Hojeong Kang, Inyoung Jang
2024, Wetlands (44)
In freshwater forested wetlands, bald cypress knees (Taxodium distichum (L.) Rich.) have the potential to emit large amounts of methane (CH4), but only a few studies have examined their greenhouse gas contribution. In this study, we measured CH4 fluxes associated with cypress knees across various climate and flooding...

Sarah E Rothenburg, Susan A Korrick, Donald Harrington, Sally W Thurston, Sarah E. Janssen, Michael T. Tate, YanFen Nong, Hua Nong, Jihong Liu, Chuan Hong, Fengxiu Ouyang
2024, Environmental Science: Processes & Impacts (26) 1975-1985
Background. Fish and rice are the main dietary sources of methylmercury (MeHg); however, rice does not contain the same beneficial nutrients as fish, and these differences can impact the observed health effects of MeHg. Hence, it is important to validate a biomarker, which can distinguish among dietary MeHg sources. Methods. Mercury...

Helen Willemien Dow, Amy E. East, Joel B. Sankey, Jonathan A. Warrick, Jaime Kostelnik, Donald N. Lindsay, Jason W. Kean
2024, Journal of Geophysical Research - Earth Surface (129)
Fire facilitates erosion through changes in vegetation and soil, with major postfire erosion commonly occurring even with moderate rainfall. As climate warms, the western United States (U.S.) is experiencing an intensifying fire regime and increasing frequency of extreme rain. We evaluated whether these hydroclimatic changes are evident...

Water District No. 1 of Johnson County,...
Forest cover lessens hurricane impacts on peak streamflow
Jazlynn S. Hall, Martha A. Scholl, James B. Shanley, Serena Matt, Maria Uriarte
2024, Hydrological Processes (38)
Cyclonic storms (i.e., hurricanes) are powerful disturbance events that often cause widespread forest damage. Storm-related canopy damage reduces rainfall interception and evapotranspiration, but impacts on streamflow regimes are poorly understood. We quantify streamflow changes in Puerto Rico following Hurricane Maria in September 2017, and evaluate whether forest cover and storm-related...

Gary N. Neuderfer, Lance E. Durfey, Michael T. Calloway, Stephen J. Smith, Justin R. Schueller
2024, Journal of Great Lakes Research (50)
Previous research evaluated the toxicity of the lampricide 4-nitro-3-(trifluoromethyl)phenol (TFM) and the combination of TFM with 1 % niclosamide (TFM:1%Nic) to multiple non-target species in the Laurentian Great Lakes. However, few toxicity studies have been conducted for species of concern in Lake Champlain (NY and VT). We conducted 12-hour flow-through toxicity...

Claire Delbecq, Jason B. Fellman, J. Ryan Bellmore, Emily J. Whitney, Eran Hood, Kevin Fitzgerald, Jeffrey A. Falke
2024, Biogeochemistry (167) 1353-1369
Riverine export of carbon (C) is an important part of the global C cycle; however, most riverine C budgets focus on individual forms of C and fail to comprehensively measure both organic and inorganic C species in concert. To address this knowledge gap, we conducted high frequency sampling of multiple...
Cold blood in warming waters: Effects of air temperature, precipitation, and groundwater on Gulf Sturgeon thermal habitats in a changing climate
Andrew Kenneth Carlson, Bethany M. Gaffey
2024, North American Journal of Fisheries Management (44) 987-1007
ObjectiveIn a changing climate, the effects of air temperature, precipitation, and groundwater on water temperature and thermal habitat suitability for Gulf Sturgeon Acipenser desotoi, listed as threatened under the U.S. Endangered Species Act, are not well understood. Hence, we incorporated these factors into thermal habitat models to...

Caelan Simeone, John C. Hammond, Stacey A. Archfield, Dan Broman, Laura Condon, Hisham Eldardiry, Carolyn G. Olson, Jen Steyaert
2024, Geophysical Research Letters (51)
Hydrological drought is a pervasive and reoccurring challenge in managing water resources. Reservoirs are critical for lessening the impacts of drought on water available for many uses. We use a novel and generalized approach to identify periods of unusually low reservoir storage—via comparisons to operational rule curves and historical patterns—to...

Martin Albert Simonson, David Bunnell, Charles P. Madenjian, Kevin Keeler, Joseph Schmitt
2024, Journal of Great Lakes Research (50)
The cisco Coregonus artedi is a coldwater fish that is distributed throughout much of Canada and the northern United States, including the Laurentian Great Lakes. Cisco historically supported large commercial fisheries in the Great Lakes during the late 1800s and early 1900s, but many populations declined and never recovered. Restoration efforts focusing...

Beth C. Long, Peter B. Moyle, Matthew J. Young, Patrick K. Crain
2024, Transactions of the American Fisheries Society (153) 559-575
ObjectiveThe Redeye Bass Micropterus coosae is a piscivore introduced into California, which has become a threat to the state's endemic freshwater fishes. It has eliminated native fishes from the middle reaches of the Cosumnes River, our study stream, which is the largest stream without a major dam on its...
