SUMMARY:Freshwater Colloquium – Small Organisms Big Impact: Microbial Insights from the Mississippi River to Caribbean Reefs
DESCRIPTION:Join the School of Freshwater Sciences for a Colloquium with guest speaker: Dr. Michael Henson \nMicroorganisms drive nutrient cycling\, regulate ecosystem productivity\, and respond quickly to environmental change\, making them strong indicators of ecosystem health. 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.

SUMMARY:Freshwater Colloquium – Stock assessment and management of lake whitefish in Wisconsin waters of Green Bay and Lake Michigan
DESCRIPTION:Join the School of Freshwater Sciences for a Colloquium with guest speaker: Dr. Iyob Tsehaye  \nLake whitefish stocks in Wisconsin’s Lake Michigan waters have historically been managed as a single stock originating from North–Moonlight Bays. 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.

SUMMARY:Freshwater Colloquium – From Weather to Paleo:  Capturing the Continuum of Climate Variability
DESCRIPTION:Join the School of Freshwater Sciences for a Colloquium with guest speaker: Dr. Raphaël Hébert \nWeather and climate variability span a continuum of timescales\, from day-to-day fluctuations to millennial-scale changes\, yet these regimes are often studied separately. 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.

SUMMARY:Freshwater Colloquium – Restoration and Conservation of an Ancient Species\, the American Paddlefish
DESCRIPTION:Join the School of Freshwater Sciences for a Colloquium with guest speaker: Dr. Jim Long \nAcipenseriformes\, including American Paddlefish (Polyodontidae\, Polyodon spathula) represents an ancient lineage of fish\, with representatives found back approximately 200 MYA. 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.

SUMMARY:Freshwater Colloquium – Currents of Life: How Flow Shapes  Complex Microbial Communities
DESCRIPTION:Join the School of Freshwater Sciences for a Colloquium with guest speaker: Dr. Emmi Mueller \nMuch of life on Earth is at the mercy of currents and flow\, which determine the organisms and resources present in an environment. 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. Her current role in the Newton Lab focuses primarily on understanding changes in antimicrobial resistance gene variants over time in wastewater and natural water systems. \nThis presentation is open to students\, faculty\, staff\, alumni and the public.

SUMMARY:Freshwater Colloquium – Agricultural Contamination in Groundwater: The Case of Nebraska
DESCRIPTION:Join the School of Freshwater Sciences for a Colloquium with guest speaker: Harshanee Jayasekera\, PhD \nAgricultural production plays a central role in Nebraska’s economy but also poses persistent risks to groundwater quality\, particularly through nitrate contamination. 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.

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. Please join us! \n\n\nThis presentation is open to students\, faculty\, staff\, alumni and the public. \n\n\n\n\n \n\nFall 2025 Colloquium Series schedule.

SUMMARY:Freshwater Colloquium: Groundwater management in Northeast Wisconsin: Potential for geogenic metals mobilization
DESCRIPTION:Erin Berns-Herrboldt will present “Groundwater management in Northeast Wisconsin: Potential for geogenic metals mobilization” as part of the School of Freshwater Sciences Spring colloquium.\nDr. Erin Berns-Herrboldt is an Assistant Professor of Water Science at the University of Wisconsin – Green Bay. 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. Most talks this semester will involve the theme of Emerging Contaminants in Aquatic Environments.

SUMMARY:Freshwater Colloquium: Novel mechanistic insights into nanoplastics release in natural environment
DESCRIPTION:Boya Xiong will present “Novel mechanistic insights into nanoplastics release in natural environment” as part of the School of Freshwater Sciences spring colloquium.\nDr. Boya Xiong is an assistant professor in the Department of Civil\, Environmental\, and Geo-Engineering at the University of Minnesota\, Twin Cities. 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.

SUMMARY:Freshwater Colloquium: Ecogenomics of freshwater lake bacteria
DESCRIPTION:Katherine (Trina) McMahon will present “Ecogenomics of freshwater lake bacteria” as part of the School of Freshwater Sciences Fall colloquium.\n \nProfessor Katherine McMahon received her BS in Civil Engineering and MS in Environmental Engineering from the University of Illinois at Urbana Champaign in 1995 and 1997 respectively. She earned her PhD in Environmental Engineering at the University of California at Berkeley in 2002. She joined the faculty in the Civil and Environmental Engineering Department at the University of Wisconsin Madison in 2003 and became cross-appointed with the Bacteriology Department in 2008. She was promoted to Associate Professor with tenure in 2008 and professor in 2013. Her research interests span multiple dimensions of the “water microbiome” including wastewater treatment and freshwater quality. She has a special interest in wastewater treatment bacteria that sequester phosphorus using an enigmatic physiology. She is heavily invested in the North Temperate Lakes Long Term Ecological Research site and directs the NTL Microbial Observatory. Finally\, she is passionate about future faculty professional development and has served as Co-Faculty Director of the Delta Program in Research\, Teaching\, and Learning at UW-Madison since 2011. She was elected as a fellow in the American Academy of Microbiology in 2018. \n\n \nFreshwater lake bacterial populations are dynamic. Ecological forces alter their community composition and evolutionary processes shape their genomes. In this presentation\, recent findings made possible through a 20-year time series of metagenomic data generated from Lake Mendota\, Madison\, WI will be shared. This study used genome-resolved approaches to examine how population-level diversity changes over time scales from weeks to decades. Results show that aquatic invasive species are restructuring the lake foodweb\, with cascading effects on lake bacteria. Climate change is impacting the populations\, through variation in precipitation patterns and intensity. This unprecedented dataset allows us to view lake bacteria through a genomics lens\, revealing the interacting forces of evolution and ecological drivers. \n\n  \n  \nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.

SUMMARY:Freshwater Colloquium: Microscopy helps reveal how nanoparticulate iron from deep sea hydrothermal vents disperses into open ocean waters
DESCRIPTION:Sarick Matzen will present “Microscopy helps reveal how nanoparticulate iron from deep sea hydrothermal vents disperses into open ocean waters” as part of the School of Freshwater Sciences Spring Colloquium.\n \n\nDr. Sarick Matzen is a soil and environmental geochemist specializing in better understanding trace metal cycling in environmental systems. He is an assistant professor in the Department of Earth and Environmental Sciences at the University of Illinois – Chicago. He received a BA in Environmental Science from Hampshire College (Amherst\, MA)\, a Ph.D. in Environmental Science\, Policy\, and Management at the University of California\, Berkeley\, and conducted NASA and NSF-funded postdoctoral work at the University of Minnesota. He draws on diverse research experiences\, including investigating nuclear waste disposal at Lawrence Livermore National Lab\, community-based soil remediation on urban farms in California\, cycling of limiting nutrients in Earth’s oceans\, and habitability of extraterrestrial ocean worlds\, to determine how the chemical form of contaminants and nutrients explains their landscape-scale transport. \nIron (Fe) is a necessary but often limiting nutrient for life on Earth. Supply by sediments and dust deposition are typically considered the main sources of iron to Earth’s oceans\, but recent advances suggest hydrothermal vents might also be an important source of bio-essential iron over the length scales of ocean basins. Dissolved iron concentrations in hydrothermal fluids are a million times those of surrounding ocean water. Most iron (>90%) precipitates close to vent sources\, but the international GEOTRACES program revealed signatures of hydrothermally-derived iron transported across deep ocean basins worldwide. However\, it remains unclear how this iron persists in the water column rather than being sequestered into sinking particles. Critical processes constraining the export of hydrothermal iron to open ocean waters occur within the first ~100 km of plume evolution. \nTo this end\, we compare hydrothermal plume particulate matter collected from the first 100 km of plumes in the low-sulfur\, high-oxygen Rainbow vent system (Mid Atlantic Ridge) and high-sulfur\, low-oxygen Endeavour vent field (Juan de Fuca Ridge\, North Pacific). We use a novel multimodal approach combining bulk to nano-scale synchrotron-based methods and electron microscopy. We show that plume chemistry affects the mineral phase of iron\, with iron(II) phases persisting longer in the high-sulfur\, low-oxygen Endeavour plume. Yet suspended particle morphology–nanoparticulate iron embedded in carbon matrices–is similar in both plumes. We explore carbon matrix chemistry and potential links to vent microbial communities. Co-located iron and carbon within marine particles drives export of iron from hydrothermal vents to open ocean waters and is a signature of nutrient-rich oceanic hydrothermal activity globally. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.

SUMMARY:Freshwater Colloquium: Data-Efficient Stream Nutrient Modeling: An Application of Data-driven Sparse Sensing
DESCRIPTION:Wasif Bin Mamoon will present “Data-Efficient Stream Nutrient Modeling: An Application of Data-driven Sparse Sensing” as part of the School of Freshwater Sciences Spring Colloquium.\nWasif Bin Mamoon is a PhD candidate in Environmental and Water Resources specialization at Marquette University in Milwaukee\, WI. His research focuses on analyzing stream nutrient (Nitrogen and Phosphorus) dynamics and modeling stream nutrients. He received his BSc and MSc in Water Resources Engineering from Bangladesh University of Engineering and Technology (BUET)\, in 2019 and 2022\, respectively. Previously\, he was a research assistant at the Institute of Water and Flood Management in Bangladesh\, responsible for assessing the impacts of climate change and applying hydrologic and hydraulic models at the watershed scale. \n\nRegular estimation or monitoring of nutrient (i.e.\, nitrogen or phosphorus) concentrations and loads is necessary for assessing stream health and evaluating nutrient pollution mitigation programs. The state of science concludes that at least daily monitoring is necessary. However\, current nutrient monitoring programs involve either infrequent grab samples or costly\, maintenance-intensive in-situ sensors\, resulting in low sampling frequencies and high uncertainties. To address this\, improved stream nutrient monitoring and modeling methods are needed. Data-driven Sparse Sensing (DSS) offers an efficient solution by reliably estimating high-frequency time series from fewer samples\, leading to more efficient sampling designs. This study applies the DSS technique to estimate stream nutrient concentrations and loads (nitrate-nitrite as NOx and phosphorous as P) using sparse measurements of nutrient concentrations and flows. The overall aim is to evaluate how DSS can identify the informative sampling times and locations and reconstruct concentration (NOx and TP) time series with minimal measurements. Furthermore\, this study examines the model’s sensitivity to the size of training data\, time span of monitored data\, and hydrologic regions. This method has a high potential to reduce the cost and effort of nutrient monitoring programs and assessments of catchment material balances. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.
