Anthropogenic changes are expected to influence behavior, stress physiology, and ultimately, lifetime fitness of animals. For social animals, external stressors imposed by human activities may interact with the social environment to either exacerbate or buffer stressors. In the context of human-induced rapid environmental change, long-term data on individually recognized social mammals has the potential to offer novel insights into the extent to which organisms can cope with social and ecological stressors. In this research, we established a new project focused on the behavioral ecology of North American beavers (Castor canadensis), a native ecosystem engineer, through monitoring using camera traps. We surveyed various public lands and identified several active family groups of beavers in West-Central Wisconsin. Our camera trap data indicate that the behavioral patterns and their interactions with other local fauna vary temporally within days and across seasons. Future research will focus on their social behaviors, including their monogamous lifestyles, dominance structures, communication systems, and movement ecology. The plethora of wildlife we monitored on our camera traps illustrates how beavers play a key role in shaping diverse and healthy wetland ecosystems. This research therefore has important implications for the management of wetlands and conservation of beaver populations in the region.

The goal of Clarifying JONAH is to design and implement data collection methods within JONAH to establish a baseline, track progress towards goals, and communicate impacts in the Chippewa Valley. Since 2007, JONAH has been working with individuals, agencies, and organizations to help make our communities healthier, safer and better places for everyone to live and work. Their work is important, yet little has been done to evaluate their impact on the Chippewa Valley. In this study, localized data will be gathered, analyzed, and shared to provide feedback on how the taskforces are advancing the goals of JONAH. I will attend and observe their meetings and conduct interviews to gather data on existing attitudes, norms, perceived behavioral control, and intentions, which I will then analyze with theory of planned behavior. This program will improve the existing communication and coordination between the stakeholders within JONAH such as WISDOM (the statewide organizer), the community organizer in Eau Claire, the seven taskforces, the volunteers partnering with JONAH, and the community at large. By tracking the relationship between JONAH’s efforts and their results, JONAH and their partners can better demonstrate their ability to resolve critical social issues impacting the Chippewa Valley.

How well does the general public understand the current recycling process in the United States? Does Eau Claire County recycle a significant amount of waste? Where does it go? This study hopes to answer these questions and more by surveying Eau Claire County residents on their recycling habits, as well as interviewing employees at the top recycling
companies operating in Eau Claire county to determine the level of public disconnect from the material reality of recycling and waste management.Many people assume the recycling system functions well and serves to reintroduce waste back into production of new consumer products and packaging, but in reality only a small amount of material is recovered. The
rest takes up space in landfills or becomes incinerated to produce electrical energy. Recycling materials comes with several costs: Time, money, and energy. Often, the costs of recycling outweigh the benefits, and without the profit incentive there are no companies willing to recycle materials.
Previously, the United States shipped most of its recyclable waste overseas to China, but following a 2017 Chinese decision to halt waste imports, American companies were forced to find alternate methods for waste disposal and material recovery. This research focuses specifically on
waste management and material recovery in Eau Claire County, but it has broader implications for the rest of the United States.

Dunn County Potter’s Field contains over 100 unmarked graves of persons from the County Poor House and the County Asylum (both now demolished) in Menomonie, Wisconsin. Community interest in locating the graves prompted non-invasive scans of Potter’s Field using ground penetrating radar (GPR). GPR transmits electromagnetic (EM) pulses into the ground, which reflect off subsurface changes before being received and recorded digitally. A 16x50m grid was collected along the site’s western boundary with a Sensors and Software pulseEKKO Pro GPR unit with 500MHz antennae. GPR traces were triggered every 0.02m via odometer wheel, and lines were collected with a spacing of 0.25m. Alternating strong and weak reflections are repeated in a sub-parallel, semicontinuous pattern throughout the grid. The strong reflections are often underlain by steep-angled hyperbolics. The reflections were identified 0.6–1.5m below the surface, each measuring 1.0m by 2.25m, and spaced 1.0m apart. Reflections were interpreted as two probable rows of individual graves. In Fall 2024, 42 crosses were placed at each probable grave, however further scanning is recommended to locate remaining lost graves. The GPR work at Dunn County Potter’s Field is a model for other cemeteries; providing means of locating and restoring honor upon unmarked graves worldwide.

This project, focusing on the Wisconsin rural-urban political divide in historical perspective, aims to answer the following research question: Is there evidence of urban-rural electoral polarization in Wisconsin from the mid-20th to the early 21st century and, if so, what were the causal factors? Researchers who have studied political polarization in recent presidential elections have sought primarily to correlate single election results to ideological differences between urban and rural communities. In contrast, this project adopts a longitudinal approach by comparing presidential election results from the Wisconsin Historical Society for the periods 1948-1968 and 1992-2020. Our research demonstrates that electoral polarization among urban cities in our sample grew between 1948-1968 and 1992-2020. However, this urban polarization was greater than polarization between the sampled urban and rural communities. Similarly, electoral polarization increased among rural towns between 1948-1968 and 1992-2020. It too, however, was greater than polarization between the sampled urban and rural communities. These conclusions suggest that standard assumptions regarding the rural-urban “political divide” in Wisconsin presidential elections are overly simplistic. Specifically, they fail to account for causal factors such as regional geography among and between urban and rural communities from the mid-20th century to the present.

Food insecurity is a significant issue facing many American households. The Supplemental Nutrition Assistance Program (SNAP) provides increased access to food for families in need. Additionally, fruit and vegetable (FV) consumption has been shown to improve health and reduce the risk of a variety of chronic diseases. However, poor nutrition among children and adults, including low FV intake have contributed to rising rates of obesity in America. It is particularly challenging for low-income households to purchase/eat the recommended amount of FV. Farmers’ markets offer a wide variety of fresh, local and healthy foods, especially FV, but data show that low-income households are much less likely to shop at farmers’ markets. The Eau Claire Downtown Farmers’ Market (ECDFM) sponsors a Market Match Program (MMP) incentivizing This presentation uses 2023 and 2024 survey data to highlight the many benefits of the MMP, while also exploring a variety of barriers to using the MMP mapped to corresponding changes that might reduce these barriers. Our results show most SNAP shoppers do not regularly shop at the market with the most reported barriers being limited market hours/locations, limited SNAP benefits running out and not remembering. We also provide demographic characteristics for all survey respondents.

However, poor nutrition among children and adults, including low FV intake have contributed to rising rates of obesity in America.

Farmers’ markets (FM) offer a wide variety of fresh, local and healthy foods, especially FV, but data show that low-income households are much less likely to shop at FM. The Eau Claire Downtown Farmers’ Market (ECDFM) sponsors a Market Match Program (MMP) incentivizing SNAP households to shop at the market. This presentation uses administrative data to tell the story and describe trends in both utilization and spending by SNAP shoppers at the market from 2018 – 2024 which importantly spans before, through and after COVID. Our results show more SNAP shoppers/SNAP spending at the ECDFM in the first two years of the pandemic, while both measures (utilization and spending) subsequently declined in the next two years coming out of the pandemic.

Mosquitoes are harmful, disease-carrying vectors that pose significant publichealth risks worldwide. Aedes aegypti, known for transmitting Zika Virus, Dengue, andyellow fever, poses a threat in various climates, while Aedes triseriatus—native toWisconsin—transmits the La Crosse virus.While much is known about adult mosquito behavior, less is understood about thesensory behaviors of mosquito larvae. To address this gap, our lab is investigating thechemosensory behaviors of Ae. aegypti and Ae. triseriatus larvae, particularly in relation toforaging. We have refined protocols using the InVision device, a high-resolution camerasystem designed for tracking aquatic invertebrates, to monitor and quantify the behavior ofmosquito larvae in response to chemical gradients emitted from a point source.With these methodologies, our research now focuses on sensory behaviorvariations across all mosquito larval and pupal stages. The mosquito life cycle consists offour instar (larval) stages, followed by a pupal stage before emerging into adulthood. Ourprevious findings suggest that L1 Ae. triseriatus and Ae. aegypti larvae do not rely onchemosensory modalities to locate food. Preliminary results indicate that foragingbehavior increases in L2-L4 instars, suggesting a developmental shift in foraging strategiesas larvae progress through these stages.

This project is titled Tick-Borne Disease Risk and Climate Change: A Survey-Based Analysis of Eau Claire County Residents’ Knowledge and Perception. Tick-borne diseases are an increasing concern in the United States, including Wisconsin, where they are common. Evidence suggests that climate change is contributing to this rise, as warming temperatures expand the geographical range of ticks and extend their active season. The aim is to assess Eau Claire County residents’ awareness and understanding of the rise in tick-borne diseases, as well as their perceptions of the role climate change plays in this issue. Data is being collected through an anonymous online survey, with 75 participants so far. Preliminary results show that most participants (76%) are between the ages of 18-24, and 92% live in suburban areas. Regarding tick-borne disease concern, 48% are somewhat concerned about contracting one, and 33% somewhat agree that the risk in their area is high. While 74% report taking preventative measures, 43% feel they are not well informed about tick-borne diseases and prevention steps. Concerning climate change, 61% of participants express being extremely concerned, and opinions about its link to tick-borne diseases are divided, with 36% strongly agreeing and 36% remaining neutral. Data collection is ongoing.

This presentation connects our work to the literature on offering incentives to SNAP shoppers at farmers’ markets. Our results show that the ECDFM MMP faces many similar challenges to other FM incentive programs. Additionally, we reference our participation in a statewide coalition to develop and expand these types of programs across the state. We conclude with policy recommendations in the context of the history of SNAP.

We aimed to increase awareness of the local flora and fauna that many people may not be aware of that live in the Chippewa River. We decided to create glass mosaics to adorn the windows of the bus stop in front of Haas Fine Arts Center as it is an accessible location for many people passing through Water Street. We used glass for its translucent properties, durability, and longevity to ensure that no harm would be brought to the local environment through use of toxic materials and to make sure it will last for years to come with little need for maintenance. The various colors of the glass pieces and the location result in the appearance changing throughout the day and seasons as the available light differs, keeping it intriguing for and visible for both visitors and the bus drivers they are waiting for. Our project resulted in a beautiful piece of art that succeeds in showcasing many local endangered fish and demonstrating the talents of graduates from the art program. The location nearby the river may also tempt curious minds to see if they can spot any of the creatures themselves.

In lakes, mosses are distributed in deeper waters than any other form of plant life. Little is known about these plant communities, and this ongoing study by Dr. Lonzarich and his students is the most comprehensive of its kind. Prior work in this lab has explored the distribution and factors affecting the occurrence of mosses from 70 lakes in Wisconsin. The objectives of this study were to identify the mosses collected from these lakes using a DNA barcoding approach, which involves DNA extraction, PCR amplification of the LTS gene (barcoding gene), and sequencing using the Sanger method. An altermative method using the RBCL gene and next-generation sequencing is also being used. By identifying the species through online gene databases, the study intends to unravel the geographic distribution patterns of deep-water moss species in the state. The study builds on previous work that found difficulties in identifying moss species based on morphological characteristics due to their unique growth forms in deep-water habitats. Initial indications from morphological assessments suggest the presence of distinct geographic patterns in the distribution of deep-water mosses within Wisconsin's lakes.

Scheduling classes is a challenging and time-consuming task. The mathematical technique of linear programming has the potential to simplify this challenge by building a model of linear constraints to find the most optimal solution that satisfies all the constraints. In this project, we are implementing a linear programming model using the DOCplex library in Python. The objective function represents instructor satisfaction with different courses and the constraints represent limitations such as the fact that one instructor cannot teach two courses at the same time. These constraints allow many ways to build a schedule. The goal of our program is to identify the most optimal solution, that maximizes the professor's satisfaction and class availability. We will present a system for encoding the preferences about number of preps and back-to-back courses, as well as discussing the advantages of using binary variables to represent combinations of courses, professors, and meeting patterns (such as MWF 9-9:50) instead of individual day-time pairs. We will also present results from adding constraints and preferences about course distribution throughout the day, depending on whether the number of sections is above or below a threshold.

Alcohol use disorders (AUD) are a critical public health issue in the United States linked to elevated morbidity and mortality. Mutual help groups (MHGs), which provide peer advice and support, are among the most widespread forms of treatment for individuals with AUD. Twelve-step MHGs like Alcoholics Anonymous (AA), are the most utilized and evidence-based interventions for AUD. In recent years, several secular 12-step/AA alternative MHGs have emerged, including Self-Management and Recovery Training (SMART) Recovery, LifeRing, and Women For Sobriety (WFS). The outcomes and mechanisms of these 12-step alternative MHGs are poorly understood. In the present study, we conducted a systematic review with the goal of updating the scientific literature on outcomes, moderators, and mechanisms of change of SMART Recovery, LifeRing, and WFS for alcohol use problems in adults with AUD. Our review was pre-registered with PROSPERO and followed PRISMA guidelines. Alcohol-related outcomes, such as alcohol abstinence/reduction in alcohol use, heavy drinking, and other negative consequences were examined. Additionally, we included analysis of engagement-related outcomes, like membership characteristics, moderators of engagement/involvement, and mechanisms of change for MHOs. Preliminary Results from our qualitative review suggest differential alcohol-related and engagement-related outcomes by MHG. These findings highlight the importance of defining similarities and differences between MHGs, as individual differences in patient history and/or ideology disprove notions of universal MHG suitability. Study findings provide valuable insights into the different mechanisms and moderators of 12-step alternative MHGs that may inform future precision medicine strategies.

Non-suicidal self-injury (NSSI) and suicide are major public health concerns and represent behaviors most practitioners will encounter during their career. Unfortunately, many mental health providers lack confidence in their skills for treating suicidal and/or self-injuring patients. Factors such as concerns about liability, emotional contagion and suicide severity appeared to moderate willingness to treat. There is a lack of research whether these patterns emerge regarding providers’ willingness to treat NSSI, a known risk factor for suicide. This study aimed to explore therapists’ willingness to treat clients with NSSI, Depression, or suicide risk. Participants were emailed through midwestern state licensing lists and asked to answer questions about a hypothetical patient from one of the three conditions. Analyses included chi-square, ANOVA, and regression. Participants showed a lower willingness to treat or accept a patient who has a history of Suicide compared to NSSI or Depression. In addition, both regression models identified significant variables, those being confidence, negative attitudes towards self-harm, and liability concerns that associated with willingness to accept or treat. We also found that the perceived risk of the patient negatvely correlated with willingness to treat. Mental health providers could benefit from increased training about suicide to build their skills and confidence.

University support services are an integral function in helping students thrive in an academic environment and have helped thousands reach their goals on the path to earning their degrees. That being said it’s important that students are fully aware of the services that are offered to them, and for them to have a positive view of said services, if we expect them to utilize these important resources. For that reason, a university’s ability to properly communicate to students the services available to them is imperative for the success of their students – this is especially true for demographics that are otherwise disadvantaged in some way, such as first-generation or disabled students. This study was primarily conducted to measure what methods may be most effective in advertising support services for students across campus, particularly focusing on Chippewa Valley Technical College and University of Wisconsin – Eau Claire students and their perceptions of various services offered by their institutions. To do this, a survey was conducted asking students about their knowledge of, opinions on, and the frequency in which they use services, as well as how they learned about them. In understanding the outcomes of different methods of advertising, universities can broaden the number of students
that are able to use their services, potentially increasing rates for graduation, student retention, and academic standing, as well as generally improving the overall experience of their students.

In 2023, Wisconsin legislators passed Wisconsin Act 20. This law required schools, including higher education institutions, to evaluate their literacy programs to align with the new Act 20 standards. Several classes offered at UWEC focus on teaching literacy methods, including UEM 433: Inclusive Literacy Methods in Grades 4-9. Our research aimed to determine if the course content taught in UEM 433 covered the components of Act 20. We first read through the Act 20 legislation and determined its key components. We then reviewed course materials, including assignments, objectives, and readings and noted whether they addressed specific aspects of Act 20. We found that the course addresses most concepts of Act 20, but not sufficiently in the area of oral language. We were able to find evidence of other areas addressed in Act 20 but determined that more information could be included in the course for areas such as vocabulary surrounding assessment and roles of faculty. We added a reading addressing middle grade oral language development to the course. Further research could be conducted to determine if oral language is a gap that persists across university middle level English Language Arts teacher education courses.

The Paleoproterozoic Penokean Orogen in Northern Wisconsin is known to host multiple volcanogenic massive sulfide (VMS) deposits which are important sources of Cu, Zn, Pb, Ag, and Au. Despite known large and potentially economic VMS deposits, limited outcrop exposure has hindered detailed reconstructions of the VMS-hosting environment to guide future exploration. Zircon petrochronology can help us give a more complete understanding of the magmatic environment in which they formed. This study sampled felsic igneous rocks to determine the timing and tectonic settings of VMS deposits in the western Penokean Orogen. Samples were pulverized and heavy mineral separates were obtained by various magnetic and density separation techniques. The zircon mineral grains were imaged by cathodoluminescence and backscattered electron microscopy at Laurentian University, Canada. Zircon isotopic (U/Pb, Lu-Hf) and trace element data were analyzed via laser ablation inductively coupled plasma–mass spectrometer (LA-ICPMS). U/Pb isotopic data constrains timing of magmatism. Trace elements and Lu-Hf data constrain the tectonic setting and crustal architecture. Preliminary results have indicated two distinct VMS-forming magmatic events during the Penokean Orogeny that have similar tectonic and magmatic styles.

The Plover Au deposit, located in Marathon County, WI, is host to a series of andesite, schist, and felsic/mafic intrusives which have undergone at least 3 phases of deformation, hydrothermal alteration, and greenschist grade metamorphism. With its proximity to the larger and better explored Reef Deposit, a more complete understanding of the formational history and geochemical footprint of the Plover prospect can add to regional understanding and better gold exploration models. For this study, two holes (PL-76-1 & PL-76-4), totaling ~1,180 linear feet of core were logged and described to highlight the volcanic stratigraphy and lithologic variety. Cores and samples were characterized by petrographic and geochemical analyses. Mineralization at the Plover deposit is characterized by cross-cutting vein networks containing boudins and vugs, and zones of brecciation. Hydrothermal alteration is suggested based on sericite/talc alteration within volcanic strata and zoned sulfide (pyrite, chalcopyrite, pyrrhotite), quartz, and calcite veins and vugs. Since high Au concentrations are typically present within brittle massive/semi-massive sulfide veins, formation of these deposits likely occurred after Penokean deformation/metamorphism and are related to a younger tectonic/magmatic event.

Modern technology and renewable energy require large amounts of metals that are derived from minerals. Many of these resources are imported, and there is a tremendous effort to domesticate our mineral extraction and processing. Several of these critical minerals, such as Ti, are found in Wisconsin, but little data is available to guide future mineral exploration efforts. This study describes the petrology and geochemistry of the Round Lake Ti Deposit in northern Wisconsin using historic drill cores stored at the WGNHS. The Round Lake intrusion that hosts the Ti mineralization is related to 1.1 Ga Mid-Continent Rift magmatism. The main intrusion is a magnetite-ilmenite rich gabbro, ranging from 35-50% magnetite-ilmenite and 15-50% coarse grained plagioclase laths. Movement and flow of magmas during emplacement formed porphyritic and trachytic textures with aligned plagioclase crystals. In addition, there are other intrusive phases associated with the magnetite-ilmenite gabbro intrusion. The anorthosite has 55-90% euhedral plagioclase, 10-15% magnetite, and 5-15% pyroxene. The magnetite rich gabbro and anorthosite make up the intrusion and is crosscut by a fine-grained gabbro and granitic dikes. Petrographic and geochemical data and interpretations improve our understanding of Ti-bearing magmatism in the Mid-Continent Rift system.

The Ritchie Creek Cu-Zn deposit, located in the Paleoproterozoic Penokean Volcanic Belt (PVB) of northern Wisconsin, is one of many volcanogenic massive sulfide (VMS) deposits known in the region. Previous studies suggest that VMS mineralization is concentrated on the western edge of a felsic volcanic center, likely formed in a back-arc or intra-arc rift environment, with mineralization occurring within bimodal volcanic sequences. These interpretations were largely based on core descriptions and comparisons to other global VMS deposits. This study aims to improve the understanding of the tectonic and volcanic setting of the Ritchie Creek deposit by re-examining historical drill cores and stratigraphic units. Over 1,000 feet of historic drill core was logged, and 22 samples were collected for petrographic and geochemical analysis, focusing on trace element characterization to better constrain the volcanic and tectonic setting. Sulfide mineralization is hosted in three main units: a quartz mica schist with disseminated sulfides, a sericite- and chlorite-altered quartz mica schist, and an intermediate meta-felsite that transitions into a rhyolitic tuff with localized sulfides and quartz veins. This project provides insights into the volcanic and tectonic processes that shaped the Ritchie Creek deposit, enhancing the understanding of VMS mineralization within the Penokean Volcanic Belt.

Minerals, such as monazite and xenotime, are an important source of rare earth (La, Ce, Nd) and high field strength (Th, Nb, Zr) elements which are essential for modern energy, communication, and military technologies. These critical minerals are often sourced in pegmatites associated with alkalic complexes, such as mines at Mountain Pass, USA, and Mount Weld, Australia. The Paleoproterozoic Eau Claire Volcanic Complex is intruded by granitic pegmatite dikes that postdate peak metamorphism, potentially linking them to 1.7 to 1.4 Ga fractionated alkalic magmas in the region. These pegmatites are highly fractionated, garnet-bearing, and low in calcium. The high concentration U, Th, La, Ce, and other rare earth elements put this pegmatite in niobium-yttrium-fluorine (NYF) class of pegmatites. This study collected bedrock samples from several locations across the Eau Claire Volcanic Complex (Little Falls, North Fork, Muskeg) to describe the trace mineral compositions. The minerals in the pegmatite samples were geochemically analyzed using a scanning electron microscope energy-dispersive X-ray spectrometer (SEM-EDS). The major minerals in the samples are mainly plagioclase, quartz, and biotite. They contain minor mineral chemistry of Fe- and Mn-garnets, samarskites, xenotimes, monazites, thorites, and barites and may represent a potential source for critical minerals in Wisconsin.

The Mineral Lake Intrusive Complex (MLIC) is a relatively large (50 x 6 km) layered mafic intrusion (LMI) located in northern Wisconsin. Because LMIs are typically rich in platinum, chromium, vanadium, and titanium deposits, the MLIC has excited much interest for its potential to host valuable economic deposits. However, the entire southern boundary of the MLIC is defined by a significant thrust fault that placed the plutonic body on top of older Archaean crust. The fault separated the upper half of the intrusion from much of its lower half (not exposed), where the bulk of the economic deposits are expected to be found. There is an orphan, ~8 km^2 ultramafic intrusion (the Rearing Pond intrusion; RPI) adjacent to and of the same age as the MLIC.  The RPI is composed of minerals expected at the base of a large LMI and may represent early crystallization within the MLIC.  LMIs are characterized by distinct top-to-bottom stratigraphy in their Mg/Fe and Ca/Na ratios. We present whole-rock and mineral Mg/Fe and Ca/Na ratios using XRF and SEM analyses to test the hypothesis that the RPI represents the earliest crystallization in the MLIC, and to estimate the volume of missing material.
