SUMMARY:01/11/24: Plant community dynamics linked to ecosystem biogeochemistry in Great Lakes coastal wetlands: modeling for both basic understanding and management applications
DESCRIPTION:Please join us for a Great Lakes Seminar Series – subscribe!\nTime: 11:00-12:00 pm EDT\nLocation: NOAA Great Lakes Environmental Research Laboratory\, Lake Superior Hall and Virtual\nPresenter: Bill Currie – Professor and Associate Dean for Research and Engagement in SEAS\, University of Michigan\nTitle: Plant community dynamics linked to ecosystem biogeochemistry in Great Lakes coastal wetlands: modeling for both basic understanding and management applications\n \nEvent Flyer \nWebinar Recording \nAbout the presentation: Linking plant community dynamics to ecosystem processes has long been a central theme in ecological modeling. In this seminar\, Bill Currie will present the development and applications of the Mondrian model\, which was designed to link across four levels of organization in coastal wetlands:  individual plant physiology\, plant population dynamics\, plant community shifts including invasive species\, and ecosystem biogeochemistry including C\, N and P cycling. Mondrian is an individual-based model in which spatially-explicit plant competition for resources causes emergent population and community dynamics\, which respond to wetland N and P inflows while also driving ecosystem N and P cycling including nutrient retention. At the same time it integrates the effects of dynamic water levels\, hydroperiod\, and water residence time on both plant survival and ecosystem biogeochemistry\, including decomposition\, C storage\, nitrification and denitrification. It has been used to study clonal plant competition broadly from a basic-science perspective as well as the integrated effects of water level and nutrient inflows on the joint outcomes of wetland C budgets and the success or failure of plant invasions in Great Lakes coastal wetlands. The model has also been used in an adaptive management framework to simulate the outcomes of management practices including burning\, mowing\, and herbicide to control invasive cattails and Phragmites. The Mondrian model was designed to be highly flexible for use by different research groups for a range of research questions and is available open-source. \nAbout the speaker: Bill Currie is a Professor and Associate Dean for Research and Engagement in SEAS. He is also Co-Director of the Schmidt AI in Science Postdoctoral Fellowship Program at the Michigan Institute for Data Science (MIDAS). Previously\, he chaired the Provost’s Faculty Transition Team to plan the new School for Environment and Sustainability\, which opened its doors in 2017. Currie is an elected Fellow of AAAS for his work in ecosystem simulation modeling\, in which he models forests\, human-dominated landscapes\, wetlands and coastal ecosystems\, biogeochemistry\, and water quality. He collaborates with investigators across a range of fields from wildlife conservation to economics\, civil engineering\, and urban planning to understand human-environment systems. He is PI on the grant to launch the SEAS Sustainability Clinic in Detroit. Currie teaches sustainability using a variety of case studies drawn from the Great Lakes region.  \n**Registration is not required** \n_____________________________________________________\nIMPORTANT VISITOR INFORMATION\nAll seminar attendees are required to receive a visitor badge from the front desk at the NOAA Great Lakes Environmental Research Laboratory facility.

SUMMARY:01/17/24: Assessing Nutrient Load Reductions in H2Ohio Constructed Wetlands: Case Studies from Brooks Park and the Burntwood-Langenkamp Wetlands
DESCRIPTION:Please join us for a Great Lakes Seminar Series – subscribe!\nTime: 12:00-1:00 pm EDT\nLocation: NOAA Great Lakes Environmental Research Laboratory\, Lake Superior Hall and Virtual\nPresenter: Silvia Newell\, Director\, Michigan Sea Grant and Professor\, University of Michigan\nTitle: Assessing Nutrient Load Reductions in H2Ohio Constructed Wetlands: Case Studies from Brooks Park and the Burntwood-Langenkamp Wetlands\n \nEvent Flyer \nWebinar Recording \nAbout the presentation: Wetlands perform critical ecosystem services\, including nutrient reduction\, flood mitigation\, and biodiversity habitat. More than 90% of wetlands in Ohio have been destroyed and most major water bodies in the state now experience annual harmful cyanobacterial blooms. The H2Ohio Initiative in part funds statewide wetland restoration to improve water quality through nutrient reduction. Dr. Newell is one of the H2Ohio Wetland Monitoring Program leads\, monitoring water quality at newly constructed wetland or restored wetlands. This talk will focus on nutrient reductions at two wetlands: Brooks Park flowing into Buckeye Lake\, a hypereutrophic lake experiencing annual harmful algal blooms. Brooks Park wetland was built at the junction of Murphy’s Run creek into Buckeye Lake\, draining a very small watershed (1.2 sq. miles) and behaves as either a flow-through wetland or a coastal wetland depending on precipitation. Preliminary data from the first year of monitoring indicates that the wetland is a sink for total nitrogen (>3000 lbs/yr)\, but a small source of ammonium (~44 lbs/yr). However\, the wetland is a very small source of total phosphorus (~42 lbs/yr)\, while a sink for soluble reactive phosphorus (~16 lbs/yr). The 90-acre Burntwood-Langenkamp Wetland Conservation Area is located at the confluence of Burntwood and Coldwater Creeks in Mercer County. This site is a former corn/soybean field in the Grand Lake Saint Marys watershed. Water enters the site from Burntwood Creek (BWC) through pump and overflow and then flows through a series of settling ponds and vegetated flats that extend for over a mile. BWC drains approximately 5\,700 acres of watershed land and can hold approximately 20 million gallons of water. Total Nitrogen (TN) concentrations at the outflow are approximately 73% lower than the TN inflow concentrations\, which average over 16.3 mg N/L for the year 2023. An approximate annual decrease thus far of ~55% in SRP concentration has been seen between the inflow and outflow with outflow concentrations averaging 0.044 mg P/L. Nutrient load reduction will likely vary as the wetlands mature\, but data from the first year indicate that both wetlands are already performing a vital ecosystem service. \nAbout the speaker: Silvia Santa Maria Newell is Michigan Sea Grant’s director\, based in Ann Arbor at the University of Michigan. A nutrient biogeochemist and microbial ecologist\, Silvia’s own research focuses on the effects of excess nutrients from fertilizer and wastewater on inland and coastal waters\, particularly harmful algal blooms (HABs) in Lake Erie. Her current collaborative work in the Lake Erie watershed focuses on engaging stakeholders (farmers\, managers\, and policymakers) to develop realistic pathways for nutrient reduction. She has held many leadership positions\, including serving as co-chair of the Great Lakes Commission HABs Collaboratory for two years and her current position as President of the Lake Erie Area Research Network. \nIn addition to serving as MISG director\, Silvia also serves as a professor at the University of Michigan School for Environment and Sustainability. \n**Registration is not required** \n_____________________________________________________\nIMPORTANT VISITOR INFORMATION\nAll seminar attendees are required to receive a visitor badge from the front desk at the NOAA Great Lakes Environmental Research Laboratory facility.
