Dr. Xiong’s research focuses on the interface of polymer science and environmental engineering\, to i) elucidate the fundamental mechanisms of polymer degradation (e.g.\, micro/nanoplastic generation) that dictate the environmental fate and shape sustainable design and management of future polymer chemicals and materials; ii) develop novel nature-inspired membrane material architecture to enable efficient separation and mitigate pathogenic contamination and fouling in engineered systems. Xiong earned a Ph.D. in Environmental engineering at Pennsylvania State University where she also obtained her M.S. in Agricultural and Biological Engineering. Xiong earned a B.S. in Biotechnology from East China University of Science and Technology. Prior to her appointment\, Xiong was working as a postdoctoral associate at MIT. She was selected as ASCE MN chapter Young Engineer of the Year in 2023 and an American Academy of Environmental Engineers and Scientists 40 Under 40 awardee in 2024. \n  \n\nThe majority of prevalent micro- / nanoplastic (MP/NPs) pollutants are derived from the degradation of bulk plastics in the natural environment. Mechanical degradation (i.e.\, abrasion and fragmentation) is a primary mechanism of MP/NP release; however\, its fundamental understanding remains elusive. Furthermore\, data generated from disparate and qualitative mechanical degradation methods are hard to unify for estimating degradation in a diverse range of environmental conditions. In this talk\, I will highlight how fragmentation and surface abrasive wear play a different role in releasing MP/NPs during the lifetime of plastics. Focusing on abrasive wear\, I will introduce our novel and quantitative methods\, particularly our lateral force microscopy-based nanoscratch method\, to mechanistically probe MP/NP release at a single surface roughness protrusion (asperity) level. Next\, I will highlight the combined effects of photo-oxidization and nanoscale abrasive wear on releasing nanoplastic release. In particular\, I will elucidate the evolution of the wear mechanism and rates of semi-crystalline polyethylene during photooxidation. These results provide an underlying mechanism and key polymer properties responsible for why photooxidation leads to more nanoplastic release via abrasive wear. Our quantitative approach will significantly advance our understanding of MP/NP release in the natural environment. The data will contribute to future predictive modeling of nanoplastic release rate as a function of polymer properties and environmental conditions. Incorporating such models into an environmental risk assessment framework will guide the early-stage design\, selection\, and management of polymer materials for responsible environmental outcomes. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom. Most talks will involve the theme of Emerging Contaminants in Aquatic Environments. Snacks will be available prior to the talk. Please join us! \n\n\nThis presentation is open to students\, faculty\, staff\, alumni and the public. \n\n\n\n\n\n\n \n\nSpring 2025 Colloquium Series schedule.

She completed her PhD in Civil Engineering in the Environmental and Water Resources Engineering Program at the University of Texas at Austin and conducted postdoctoral research at Oak Ridge National Laboratory. Her research experience includes studying the fate of organic groundwater contaminants\, biogeochemical controls on carbon release from Arctic permafrost soils\, metals release from aquifer sediments\, and nutrient cycling in stream hyporheic zones. \n\nGroundwater quality can be impacted by metals released from aquifer minerals\, potentially causing human health concerns. When aquifer sediments are relatively undisturbed\, metals bound to minerals remain stable\, but during transitions in water level – due to variations in groundwater recharge or over-pumping – metals can be released to groundwater. This project evaluates the history of groundwater use in the Northeast Wisconsin Groundwater Management Area (GMA) for the confined Cambrian-Ordovician aquifer\, and explores the potential for metals release due to oxidation during aquifer drawdown. \n \nTo evaluate these changes\, (1) groundwater was sampled across the GMA for evaluation of water chemistry\, (2) a monitoring well was installed to improve groundwater level monitoring in the southern portion of the GMA\, and (3) batch leaching experiments were conducted under oxic and anoxic conditions with rock cuttings from the newly installed monitoring well to evaluate potential for metals release. Initial leaching experiment results show that nickel and cobalt increased over time in oxic experiments\, but not in anoxic experiments\, and negligible arsenic was observed over the experimental timeframe. This study provides initial results that support improved understanding of metals release from oxidized GMA aquifer sediments. Findings from this study will inform the development of effective groundwater management strategies\, ensuring the sustainability and safety of water resources in the Northeast Wisconsin GMA. \n\nThe Spring 2025 Freshwater Colloquium series takes place in the GLRF Ballroom.

He will present his research on the possible future uses of the Dredged Material Disposal Facility at the Port of Milwaukee. This facility is part of a broader network of dredge-spoil sites across the Great Lakes. He will also discuss these newly created lakefront lands in a basin-wide context and include examples of closure and conversion to future public uses in other parts of the Great Lakes. \nBuilding on prior workshops\, including the 2019 National Science Foundation Sustainable Urban Systems Workshop and the 2022 Great Lakes Higher Education Consortium Workshop\, Prof. Wasley’s research serves as a test case for collaboration among academic researchers\, design professionals\, and policymakers to develop innovative\, nature-based design solutions for Great Lakes cities. In August of 2024\, he convened a meeting of experts on issues associated with the dredged material disposal facilities and the future of this research aligns with the Freshwater Collaborative of Wisconsin’s Grand Water Challenge on Great Lakes Management and Restoration. \nProf. Wasley is Director of the Institute for Ecological Design and the former chair of the Department of Architecture. He is the past president of the Society of Building Science Educators and the Wisconsin Green Building Alliance: An Affiliate of the United States Green Building Council. He was a founding member of WGBA in 1997. \nThis event is co-hosted by the Freshwater Collaborative of Wisconsin and is part of a quarterly online water symposium series in partnership with the Great Lakes Higher Education Consortium and Council of the Great Lakes Region. \nRegister for the event here!

As an environmental chemist he studies the occurrence and fate of anthropogenic chemicals in natural and engineered systems. Before joining the SES faculty in 2023\, he was a research scientist at Biobot Analytics\, a consultant at Exponent\, and a research scientist with the North Carolina PFAS Testing Network. Additionally\, he has held adjunct/lecturer appointments in the Chemistry Department at Tufts University and the Department of Civil and Environmental Engineering at MIT. He completed his post-doctoral training with the Environmental Chemistry Group at ETH Zurich and his PhD with Professor Lee Ferguson at the Nicholas School of the Environment at Duke University. \nPer- and polyfluoroalkyl substances (PFAS) are a class of organic contaminants occurring ubiquitously in aquatic environments owing to their wide-spread consumer and industrial use and the recalcitrance of carbon-fluorine bonds toward environmental transformations. PFAS accumulate in sediments and biota and are known to cause ecological and human health effects. PFAS use in industry and consumer goods leads to their occurrence in treated wastewater and residual biosolids. Furthermore\, recent research indicates that stormwater may transport PFAS from urban landscapes into aquatic ecosystems. Considering potential future regulations on levels of PFAS in wastewater discharges\, knowledge of PFAS sources in urban aquatic environments is essential for determining efficacy of any proposed discharge limits or ambient water quality standards. The Chicago Area Waterway System (CAWS) presents a unique opportunity for studying the sources and fate of PFAS in urban aquatic systems because the CAWS surface waters are highly impacted by treated wastewater effluent\, combined sewer overflows\, and stormwater runoff. However\, there are currently few data available on levels of PFAS in CAWS surface waters. To better understand current levels of PFAS in the CAWS\, we conducted a monitoring campaign in major CAWS waterways with varying degrees of stormwater runoff and wastewater influence. Samples were analyzed using solid phase extraction and high-performance liquid chromatography tandem mass spectrometry for >30 PFAS of regulatory concern. This presentation will explore relationships between PFAS occurrence and probable PFAS sources and evaluate PFAS concentrations considering current ecological health guidelines. \n\n\nThis final seminar of the Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom. Another fascinating talk around this semester’s overarching theme of Emerging Contaminants in Aquatic Environments.

Designated by EPA as Areas of Concern (AOCs) in the 1980s\, both systems provide natural laboratories for assessing long-term pollution trends. This presentation will explore case studies on the depositional history of black carbon (soot)\, toxic metals (Cu\, Pb\, Zn\, Cd\, Hg\, Co\, Ni\, Cr\, and As)\, and polyfluoroalkyl substances (PFAS) in Green Bay sediments over the past 50-100 years\, with comparative insights from Milwaukee Harbor. \nDr. Guo’s major research focus is on aquatic biogeochemistry\, with an emphasis on the role of natural organic matter in governing the reactivity\, fate and transport of chemical species\, including trace metals\, radionuclides\, nanoparticles\, microplastics\, PFAS\, and other contaminants. He received his Ph.D. degree in Chemical Oceanography from Texas A&M University\, College Station. After working as a postdoc and assistant research scientist at Texas A&M-Galveston\, Dr. Guo joined University of Alaska Fairbanks in 2000 as a research professor in the International Arctic Research Center and then University of Southern Mississippi in 2005 as a faculty member in the Department of Marine Science. Dr. Guo has been a professor in the School of Freshwater Sciences at the University of Wisconsin-Milwaukee since 2012. Dr. Guo has authored/coauthored over 240 peer-reviewed publications\, with an H-index of 70 and over 17\,000 citations based on Google Scholar. His research influence is specifically recognized by ScholarGPS®\, which ranked him #4 globally in Dissolved Organic Carbon and #5 in Organic Matter based on publications from the prior five years (2022). He received the 2023 UWM Senior Faculty Research Award. \nSam earned her B.S. in Geography with a minor in Chemistry from UW-Whitewater in 2024.

The field of environmental toxicology has recently embraced a “one health” approach\, with increased focus on understanding the underlying mechanistic effects to improve species extrapolation. While many are shifting towards in silico and Adverse Outcome Pathway approaches\, in vivo toxicity testing using zebrafish and fathead minnow larvae allows for integrated systematic toxicity screening using physiologically complex endpoints and incorporation of latent and transgenerational effects following early exposure to environmental contaminants. Dr. King-Heiden will share the approach she has used to integrate experimental endpoints useful for predicting latent and long-term risks for adverse health effects in both wildlife and humans\, focusing on her most recent studies using neonicotinoid pesticides and PFAS. \nDr. King-Heiden is a Professor of Biology and River Studies Center at UW-La Crosse\, who specializes in the field of aquatic toxicology\, developmental biology\, and reproductive physiology. She earned her PhD from UW-Milwaukee Department of Biology\, working with Dr. Carvan at the now School of Freshwater Sciences\, studying the reproductive toxicity of Dioxin. She continued this work as a postdoc at the Molecular and Environmental Toxicity Center at UW Madison\, exploring the latent and transgenerational reproductive toxicity of dioxin\, and developmental toxicity of nanomaterials. She has been in the Biology department at UW-La Crosse since 2008. At this comprehensive university\, she is focused on teaching. Her research revolves around undergraduate and MS students\, with a continued focus discerning the impacts of embryonic exposure to emerging contaminants of concern\, using primarily zebrafish and fathead minnows as a model. Her work reveals how exposure to these contaminants influence physiological and behavioral endpoints of ecological importance\, with implications for ecological resilience as well as human health.

In this talk\, I will share results from a global-scale transient simulation of the global water table over the past 21\,000 years\, including both groundwater and lake surfaces. The simulation is obtained using the Water Table Model (WTM)\, forced by climate simulation data and topography that changes through time as a result of glacial isostatic adjustment (GIA). Our results highlight the strong correlation between precipitation and water table depth\, and the impact of melting ice sheets on lake storage. We will discuss the impacts of changing groundwater storage on global sea level\, and will also examine the impacts of lakes and groundwater on GIA. \nKerry Callaghan is an Assistant Professor at the University of Illinois Chicago. She obtained her PhD from the University of Minnesota\, where she developed the Water Table Model (WTM)\, and then completed a postdoc at the Lamont-Doherty Earth Observatory\, Columbia University\, before starting her current position. Prof. Callaghan’s research focuses on the interactions between water and our changing landscape and Earth system. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

PFAS are a large class of man-made chemicals used in a wide range of applications such as metal plating\, food packaging\, non-stick coating\, waterproof and stain-resistant fabrics\, and firefighting foams. Because of their numerous sources and applications\, these chemicals are present in the environment as complex mixtures of many different types of PFAS compounds. Once in the environment\, PFAS do not break down completely due to their highly stable fluorinated carbon bonds\, allowing them to persist and accumulate in water supplies\, biota\, and humans. Our laboratory in the Center for PFAS Research and the Department of Fisheries and Wildlife at Michigan State University investigates the accumulation of PFAS mixtures in the Great Lakes region and the impacts of PFAS exposure on native freshwater fishes. This presentation will discuss our field and laboratory research characterizing the distribution of PFAS in environmental matrices\, the bioaccumulation of PFAS in biota\, and the effects of PFAS on the growth\, reproduction\, and physiological condition of native fishes. Together\, this research can inform evidence-based decision-making surrounding ecosystem health\, remediation\, fish consumption advisories\, and water quality standards in the Great Lakes region. \nDr. Rachel Leads is an Aquatic Ecotoxicologist and Postdoctoral Research Associate in the Department of Fisheries and Wildlife and Center for PFAS Research at Michigan State University. She received her M.S. in Marine Biology from the College of Charleston and her Ph.D. in Biology from the University of North Texas. Her research characterizes the physiological mechanisms and ecological effects of contaminants and environmental stressors in marine and freshwater organisms. Currently\, Dr. Leads studies the impacts of per- and polyfluoroalkyl substances (PFAS) on native fish in the Great Lakes region. Overall\, her work uses both field and laboratory assessments to understand the mechanisms and impacts of contaminant exposure on aquatic organisms across multiple levels of biological organization\, from molecular to whole-organism responses. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

This presentation first highlights predictive models built using measurements of Staphylococcus aureus and fecal indicator bacteria across fresh\, brackish\, and marine waters to better understand environmental drivers and mitigate risks to recreators. Next\, modeling is used to evaluate the efficacy of wastewater-based epidemiology by comparing concentrations of SARS-CoV-2 in wastewater to reported case counts using a novel testing instrument. Finally\, this work explores how microbial indicators identified from conveyance systems and within wastewater treatment processes can help detect septic or stressed conditions that may contribute to effluent quality issues. Together\, this research demonstrates how integrating pathogen monitoring\, microbial community profiling\, and modeling across watersheds and wastewater systems can inform water quality management\, enhance treatment diagnostics\, and strengthen public health forecasting. \nDr. Maria Steadmon is a postdoctoral researcher in the McLellan Lab at the School of Freshwater Sciences. She earned her Ph.D. in oceanography from the University of Hawaiʻi at Mānoa and her doctoral research centered on the detection and quantification of microbial pathogens across aquatic environments.

Environmental stresses such as sunlight\, temperature fluctuations\, wet/dry cycling or microbial forces affect the longevity or degradation of plastics. Assessing the fate of plastics under these stresses allows us to accurately predict the service lifetime of plastics used in infrastructure (or evaluate the extent of the plastic pollution problem. This talk will center around some of the fundamental chemistry questions the Maurer-Jones group asks around how plastics degrade and what are the implications for them in the environment. Insights my group has made we will be a jumping off point to explore some questions or concepts around the future of plastic materials. \nMelissa Maurer-Jones did her BS in chemistry at University of St.Thomas in St. Paul MN and completed a Chemistry Ph.D. at University of Minnesota – Twin Cities working for Dr. Christy Haynes where she studied the toxicity response of mammalian and bacterial models to engineered nanoparticles. She went on to do a postdoc with Dr. Kris McNeill at ETH Zurich studying the environmental photochemistry of a plastic material.

Because a large majority of Nebraskans rely on groundwater for drinking\, understanding the effectiveness of groundwater protection policies is critical for environmental sustainability and public health in the state. I (and co-authors) examine agricultural contamination in Nebraska with a focus on evaluating the impact of policy measures such as Wellhead Protection Areas (WPAs) and the Conservation Reserve Program (CRP) on groundwater quality. Using comprehensive data from the Nebraska Groundwater Quality Clearinghouse (1996–2019)\, comprising over two million nitrate observations from approximately 33\,000 wells\, we provide evidence of statistically and economically meaningful reductions in groundwater nitrate concentrations associated with these policy interventions. Our main finding is that improvements in water quality materialize gradually\, often unfolding over decades rather than years. These results underscore the importance of long-term monitoring systems and sustained policy commitment when addressing nonpoint-source agricultural pollution. \nHarshanee Jayasekera is an interdisciplinary social scientist whose work focuses on groundwater quality management and long-term sustainability. Her research examines the intersection of groundwater quality and agriculture\, with particular attention to how policy and management decisions shape long-term resource outcomes. Through her research and outreach\, she supports evidence-based groundwater management strategies that balance agricultural productivity with environmental quality. She works extensively on groundwater sustainability issues in Nebraska\, providing insights to inform decision-making at local and state levels. Her current projects examine the long-term policy implications of agricultural land retirement on nutrient pollution in Nebraska\, the effectiveness of wellhead protection areas in improving groundwater quality\, and the human health impacts of environmental exposures in agricultural regions. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

In aquatic ecosystems\, these currents shape the ecological and evolutionary trajectories of the diverse microbial communities that inhabit them. In this presentation\, I will discuss how microbial communities in both natural and man-made water systems are shaped by physical flow\, specifically variation in residence time\, or the time organisms and resources spend in a system. I will also discuss how these systems are shaped by the flow of energy\, such as through variation in metabolic activity and functions like antibiotic resistance\, focusing on how this knowledge may shape management of these systems from an ecosystem and human health perspective. \nDr. Emmi Mueller is a Postdoctoral Research Associate in the Newton Lab in the School of Freshwater Sciences. She earned her Ph.D. in Evolution\, Ecology\, and Behavior from Indiana University\, where her doctoral research focused on the importance of residence time and metabolic heterogeneity in structuring lake microbial communities.

American Paddlefish is the only remaining extant species of its family\, since the recent extinction of the Chinese Paddlefish (Psephurus gladius). American Paddlefish occur in North America and are large-bodied (> 2 m total length [TL])\, potamadromous\, and have fertilized eggs that stick to hard substrates with pelagic larvae that develop while drifting and moving downstream. Overharvest and habitat fragmentation has reduced Paddlefish populations across its range\, including Oklahoma. In Oklahoma\, restoration efforts have returned the species to former parts of its range\, but factors associated with restoration success have just begun to be assessed. Since 2019\, I have been working with state and federal conservation partners to examine factors associated with Paddlefish restoration success including the development of novel monitoring techniques that include the use of side-scan sonar. Suitable substrate availability does not appear to limit Paddlefish reproduction\, but excessively turbid waters in spawning and rearing environments may. Side-scan sonar is an accurate tool for assessing abundance and can be used to monitor spring spawning movements. Further\, side-scan sonar appears to be a useful monitoring method to identify early age classes of fish. \nJim Long grew up in the Ozarks of southwest Missouri and received a PhD from Oklahoma State University in 2000. Afterward\, he went to South Carolina as a Fisheries Research Biologist investigating fish community structure in tidal freshwater wetlands. From 2002 to 2009\, Jim worked with the National Park Service as the Fishery Biologist for the southeast region. In 2009\, Jim moved back to Oklahoma as an Assistant Unit Leader and become Unit Leader in 2016. Jim’s research focuses on management-driven questions related to the process of fisheries management\, social dimensions\, early-life history of fishes\, and effects of invasive species on aquatic communities. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

My work explores how to bring these scales together within a unified framework that captures spatial structure\, temporal persistence\, and dynamical linkages across scales by combining diverse environmental datasets. I will first introduce my ongoing work with Prof. Sergey Kravtsov on data-driven forecasting from daily to seasonal timescales using high-resolution reanalysis products that integrate instrumental and satellite observations since 1980. I will then turn to earlier work using longer instrumental records\, climate model simulations\, and paleoclimate reconstructions to examine how the spatial and temporal covariance structure of climate variability evolves from decadal to centennial and millennial timescales\, highlighting both what we know—and what remains uncertain—about long-timescale climate variability. Together\, these perspectives suggest that similar statistical structures may underlie climate variability across a wide range of timescales and point toward new ways of connecting modern observations with paleoclimate evidence. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

However\, over the last couple of decades\, this stock has declined in line with broader Lake Michigan trends linked to dreissenid mussel-induced food web shifts. Conversely\, the southern Green Bay population has seen a substantial resurgence after a century-long collapse. Telemetry and tagging data reveal minimal mixing between these groups: Green Bay-spawned fish rarely migrate to the lake side of the Door Peninsula\, and North–Moonlight Bays fish largely remain in northern Lake Michigan. This divergence in productivity and distribution\, further evidenced by the emergence of a major recreational fishery in Green Bay\, necessitates a shift in management. Separate stock assessments confirm that whitefish abundance is now significantly higher within Green Bay than on the lake side of the peninsula. Even so\, assessment models show the number of whitefish in Green Bay has declined by about half since their peak around 2012. While the decline of lake whitefish is likely driven largely by food-web disruptions caused by invasive mussels\, fishing pressure also plays a role. These findings suggest that spatial harvest allocations must be readjusted to reflect the contemporary regional productivity of these distinct stocks. \nIyob Tsehaye is a Great Lakes Quantitative Fisheries Research Scientist with the Wisconsin Department of Natural Resources (DNR). His research focuses on the assessment and management of recreationally and commercially important fisheries\, such as lake whitefish\, yellow perch and walleye\, as well as investigating predator-prey interactions to inform stocking decisions for salmonine predators. Before joining the DNR in 2015\, Iyob was a postdoctoral researcher at the Quantitative Fisheries Center at Michigan State University. He earned his PhD and MSc degrees from Wageningen University in the Netherlands and his Bachelor’s degree from the University of Asmara in Eritrea. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

In this seminar\, we will discuss how microbial community structure and assembly reveal patterns of environmental organization across large spatial scales\, and how shifts in core microbial taxa reflect underlying ecological processes rather than simple changes in nutrient levels\, using the Mississippi River as a case study. These patterns provide insight into how large rivers process and transform nutrients during downstream transport. We will also cover ongoing work on Caribbean coral reefs\, where a pathogenic ciliate has contributed to widespread mass mortality of sea urchins. By combining environmental sequencing with cultured isolates\, we are exploring how microbial dynamics intersect with disease emergence in a rapidly changing ocean. Together\, these studies show how microbial communities\, from a continental-scale river network to tropical reef ecosystems\, serve as a powerful lens for understanding environmental change. \nMichael Henson is an Assistant Professor of Biological Sciences at Northern Illinois University and leads the Aquatic Microbiology Lab. His research focuses on how microbial communities respond to environmental change and how those responses scale to influence ecosystem processes. He takes an integrative approach that spans cultivation\, physiology\, and genomics\, linking organismal traits to patterns observed at ecosystem scales.\n\nHe earned his PhD at Louisiana State University\, where he developed a foundation in microbial ecology and began combining molecular tools with environmental data to study community structure and function. He then completed postdoctoral training at the University of Southern California and the University of Chicago\, where he further integrated cultivation-based approaches with genomic and ecological analyses to better connect microbial physiology to ecosystem dynamics.\n\nHis current research spans both freshwater and marine systems. In the Mississippi River\, he investigates how microbial communities maintain strong spatial structure despite temporal variability\, and how changes in water quality alter key taxa and ecosystem function. In marine systems\, his work focuses on host–microbe interactions and disease\, particularly through research on the ciliate pathogen affecting sea urchins\, where our lab is working to link ecological changes with disease outbreak patterns.\n\nOutside the lab\, he enjoys gardening with his husband\, traveling\, and spending time outdoors backpacking and camping. At home\, they share their lives and home with their two dogs\, Tyler and Emmy.\nThis presentation is open to students\, faculty\, staff\, alumni and the public.

To strengthen surveillance capacity\, the U.S. Fish and Wildlife Service (USFWS) has expanded its Early Detection and Monitoring program to incorporate eDNA metabarcoding as a large-scale\, multi‑jurisdictional tool for identifying emerging invaders and characterizing fish community diversity. \nSince 2024\, USFWS field offices—supported by two specialized USFWS genetics laboratories—have implemented coordinated eDNA surveys throughout the Great Lakes basin. This collaboration is producing one of the region’s most extensive metabarcoding datasets to date\, revealing basin‑wide biodiversity patterns and highlighting potential indicators of newly arriving or expanding AIS. The program also emphasizes partnership with tribal\, state\, and federal natural resource agencies\, creating a shared early detection network grounded in consistent methods and communication. \nIntegrating metabarcoding into a broad operational framework has generated key lessons for developing effective early detection networks. These include refinements to sampling design\, improvements in laboratory workflows that increase throughput and reduce error\, and approaches for ensuring consistent interpretation of metabarcoding data across organizations. \nPreliminary results illustrate both the strengths and challenges of using metabarcoding at scale. The approach provides enhanced sensitivity for detecting low-abundance AIS signals\, supports more complete characterization of fish communities across heterogeneous habitats\, and highlights logistical and coordination challenges inherent in standardizing protocols across multiple agencies and jurisdictions. \nOur work showcases how a coordinated\, basin-wide eDNA metabarcoding framework can support AIS early detection and provide useful insights into best practices that may be transferable to other regions working to develop or expand molecular early detection networks. \nRachael Giglio is a geneticist with the U.S. Fish and Wildlife Whitney Genetics Lab located in Onalaska\, WI.

Presentations are open to the public. \nAll events will take place on Mondays from 3:30-4:20 p.m. in-person in the GLRF Ballroom. \nThe School of Freshwater Sciences Great Lakes Research Facility\, is located at 600 E. Greenfield Ave. \nFull schedule \nNOAA’s Global Systems Laboratory (GSL)\, part of the Office of Oceanic and Atmospheric Research\, seeks to improve Earth-system prediction capabilities across all weather-related hazards including severe convective storms\, intense rainfall\, winter storms\, tropical systems\, and phenomena such as wildfire smoke\, dust\, and pollen. GSL has a rich legacy in developing modeling systems for NOAA operations\, including the operational Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) models\, and in contributing to the development of Unified Forecast System (UFS) applications such as the first version of the Rapid Refresh Forecast System (RRFSv1) and the Global Forecast System (GFS). Given the increasing frequency of damaging high-impact weather events in recent years\, there is an increasing need for high-resolution modeling systems that can accurately\, faithfully\, and explicitly resolve precipitating phenomena\, fire-weather behavior\, aerosol radiative and cloud feedbacks\, and urbanization influences to improve forecast skill and inform improved end-user decision-making. Extensive development\, testing\, and evaluation at GSL and elsewhere over the last two years has indicated that the Model for Prediction Across Scales\, or MPAS\, can address these predictive needs. My presentation will provide a high-level overview of how the proverbial sauce is made: what is MPAS\, how physics processes are represented within MPAS\, the vital role of incorporating atmospheric observations to provide an accurate initial atmospheric representation\, how extensive computational codebases are maintained\, and the importance of rigorous testing and evaluation to guide our scientifically grounded\, hypothesis-driven model development activities. I will also present the outcomes of multiple testing and evaluation activities\, which demonstrate the substantial promise of MPAS-based weather prediction systems for future NOAA operational weather prediction systems to meet NOAA’s Numerical Weather Prediction Moonshot goal of world-leading skillful\, reliable\, and useful global\, storm-scale\, Earth-system model forecasts.

Presentations are open to the public. \nAll events will take place on Mondays from 3:30-4:20 p.m. in-person in the GLRF Ballroom. \nThe School of Freshwater Sciences Great Lakes Research Facility\, is located at 600 E. Greenfield Ave. \nFull schedule \nResource polymorphisms are common among charr (Salvelinus) ecomorphs. In North America\, there are lake charr (Salvelinus namaycush) ecomorphs exhibiting variations in morphology\, physiology and behavior. Many of these occur in deep lake ecosystems (e.g.\, Lake Superior\, Great Bear and Slave Lakes) where depth provides a variety of habitats varying in temperature\, pressure\, and forage composition. Which phenotypic variations are heritable or result from environmental plasticity is a fundamental question for understanding the sympatric evolution of these ecomorphs and may have profound impacts on their resiliency to habitat change in the future. In Lake Superior\, there have been four reported ecomorphs; leans\, siscowets\, redfins and humpers. However\, based on observations particularly in complex bathymetric habitats (e.g.\, Isle Royale\, Stannard Rock\, Klondike Reef)\, there are certainly more ecomorphs that have yet to be described. So far\, ecomorphs (particularly leans and siscowets) can be differentiated based on morphometry\, growth\, habitat\, incidence of skip spawning\, pyloric caeca\, and to a lesser extent diet. They also exhibit physiological differences in the amount of lipid and glycogen stored in the muscle and liver as well as in the effects of lamprey wounding. This talk will synthesize efforts that have been made to delineate which of these phenotypes have a genetic basis and to what extent. It relies heavily on the results of a 15-year\, multi-generational common garden rearing experiment of lean and siscowet lake charr.

Presentations are open to the public. \nAll events will take place on Mondays from 3:30-4:20 p.m. in-person in the GLRF Ballroom. \nThe School of Freshwater Sciences Great Lakes Research Facility\, is located at 600 E. Greenfield Ave. \nFull schedule \nFor over 100 years\, the Emscher River was the open sewer of the Ruhr\, the center of Germany’s coal-mining and steel-production capacity. Mining related land subsidence of made the ground too unstable for the creation of a conventional sewer system\, and frequent flooding in the region necessitated that the sluggish river be channelized. \nThe Ruhr Valley is twice the size of the Milwaukee River watershed. With a population of over 5 million spread between twelve mid-sized cities\, it is the largest and most densely settled urban agglomeration in Germany. Roughly half of that population lives within the Emscher River watershed\, which is roughly twice the size of the Menomonee River watershed. Like the Menomonee and Kinnickinnic\, the dominant character of the Emscher is industrial. \nMuch like here\, the region de-industrialized starting in the 1970’s. In 1988\, the government of North Rhine-Westphalia initiated the Internationale Bauausstellung (IBA) Emscher Park\, a ten-year plan to focus investment on the ecological restoration and economic reinvention of the region. Starting in 1990\, the Emschergenossenschaft (EGLV)\, the regional water authority\, began the 30-year\, 5.3 billion Euro construction of a modern sewer system and the restoration of the Emscher river. \nThat project\, the largest river restoration project in Europe\, is now complete\, and the EGLV is seeking to map out the next phase of transformations that will adapt the Ruhr to the challenges of the 21st C. \nWith my own water-centric research focusing on our own Inner Harbor\, Milwaukee\, and the post-industrial waterfronts of the Great Lakes Basin\, I have long been fascinated with the ecological and cultural project of the New Emscher. This last spring I spent three weeks in Essen as a guest of the EGLV. Where in the past I have sought inspiration from individual projects\, this time my aim was to understand the newly reconstructed river and its watershed as a whole. My ongoing goal is to be to provide the EGLV with a unique designer’s sensibility\, and to play a consulting role in the current visioning process. \nThis talk will present design work that I undertook while visiting the EGLV\, with the goal of coming to understand the river through my own speculations. As a designer of ecological urban waterscapes\, I have a clear sense of the complexities of seeking to create a connection to nature in compromised environments. I am philosophically committed to the idea of ‘reading the land’ through the ways that water flows; of teaching ecological literacy through design starting with watershed awareness. The polderized landscape of the Emscher has confounded me. I find the river and it’s tributary landscape completely uncanny. It is that uncanny nature that my work explores and that this talk will seek to work through. \nJames Wasley is a Professor in the UWM Architecture Department and is a Director of the Institute for Ecological Design. He is also an Affiliate Professor at the UWM School of Freshwater Sciences. His research focuses on designing and implementing ecological urban waterscapes. Grounded in the Great Lakes\, this research has recently expanded to include a comparative focus on the restoration of the Emscher River in the Ruhr region of Germany and on green/blue infrastructure in German urban design. \nProfessor Wasley was a Water Policy Scholar at the SFS Center for Water Policy in 2017 and again in 2024. In the spring of 2023 he was a Visiting Professor at the Technical University of Dortmund\, DE. Also in 2024 he participated in the inaugural class of the Association of Collegiate Schools of Architecture Academy for Public Scholarship on the Built Environment: CLIMATE ACTION.

Presentations are open to the public. \nAll events will take place on Mondays from 3:30-4:20 p.m. in-person in the GLRF Ballroom. \nThe School of Freshwater Sciences Great Lakes Research Facility\, is located at 600 E. Greenfield Ave. \nFull schedule \nMicro- and nanoplastics (MNPs) are a contaminant of emerging concern and have been found in everything from the air we breathe to personal care products\, food and drinking water. They are even present in medical supplies like intravenous fluids. Due to their ubiquity\, this area of research has been growing rapidly over the past several years. However\, a key limitation in many studies is the inability to include smaller MNPs because of analytical limitations. This is especially concerning as these smaller particles have the highest potential to cross cellular barriers and accumulate in the body. To address this gap\, we developed a method to isolate and analyze smaller MNPs from complex environmental and biological matrices. This method prepared the MNPs for analysis using scanning electron microscopy (SEM) to determine the size\, shape\, and number of the particles\, and optical photothermal infrared spectroscopy (O-PTIR) to identify polymer types. The method was validated using a known concentration of polystyrene nanoparticles in river water and in human blood\, with recovery efficiencies of 81% and 82%\, respectively\, demonstrating its effectiveness in the applied matrices. The application of this method allowed for the analysis of MNPs in natural freshwater systems (Lake Erie)\, engineered environments (drinking water treatment)\, consumer products (bottled water)\, as well as human tissue samples (bone marrow) leading to an overall improvement in our understanding of their presence\, transport\, and exposure pathways. \nMegan is currently a postdoctoral fellow at the P&G Digital Accelerator at the University of Cincinnati where she works as part of the Global Product Stewardship-Environmental Fate Team working to improve the methods used to evaluate the biodegradability of down the drain chemicals in freshwater systems. She recently completed my Ph.D. in Environmental Science at Ohio State University where her research focused on isolating and analyzing micro and nanoplastics from aqueous and biological samples and evaluating their fate and transport in drinking water treatment systems. Megan completed her M.S. in chemistry and B.S. in environmental science at Oakland University\, where she worked to improve microbial source tracking methods to identify the sources of fecal contamination as part of a recreational water quality monitoring program.

DESCRIPTION:The School of Freshwater Sciences’ Freshwater Colloquium creates a platform for students\, faculty and scientists to discuss their research and emergent issues related to freshwater resources. Presentations are open to the public. \nAll events will take place on Mondays from 3:30-4:20 p.m. in-person in the GLRF Ballroom. \nThe School of Freshwater Sciences Great Lakes Research Facility\, is located at 600 E. Greenfield Ave. \nFull schedule \nThe OneHealth approach recognizes the importance of interconnections between human health and the environment. An exemplary international effort of this nature is the long-standing U.S.-Canada Great Lakes Water Quality Agreement (GLWQA)\, which aims to restore and protect roughly 21% of the global surface freshwater supply. Since its inception in 1972\, the U.S.-Canada GLWQA has set forth the bi-national environmental and scientific goals to protect and restore the Laurentian Great Lakes. Through the Great Lakes Restoration Initiative\, a U.S.-led multi-federal agency program that begin in 2010 and which is aligned with the GLWQA\, partner organizations have laid the groundwork for identifying\, remediating\, and restoring degraded coastal areas and putting them on the path to revitalization by communities. However\, while nearly 10\,000 projects have been completed to date\, a systematic understanding of environmental and human wellbeing changes resulting from these projects is yet to be developed\, and impacts\, when measured\, are typically documented at a project-level. In this seminar\, I will discuss new approaches for measuring human wellbeing and environmental impacts from remediation and restoration projects\, as well as share recent research documenting impacts at both the project- and ecosystem-scale. These studies reveal both design-based trade-offs in project outcomes as well as on-the-ground improvement in ecological health and human wellbeing factors. \nDr. Joel Hoffman is the Director of Research at the University of Minnesota Natural Resources Research Institute (NRRI; 2025-current).
