    County-Scale Climate Projections Over Minnesota and the Effects of Lakes
    (Water Resources Research, 2025-03-12) Liess, Stefan; Roop, Heidi A.; Twine, Tracy E.; Clark, Suzanna; Coffman, Dena; Doma, Dhondup; Farris, Amanda; Fernandez, Alejandro; Gorman, Jack; Meyer, Nathan
    Climate projections for three future shared socioeconomic pathway scenarios from six CMIP6 global climate models (GCMs) were dynamically downscaled over Minnesota with the regional Weather Research and Forecasting model coupled to a lake model at 4-km horizontal resolution representing energy and moisture fluxes over more than 60 lakes inside the state borders. Warming over Minnesota is projected to increase in all seasons, especially in winter. Snow depth and lake ice cover is expected to decrease. However, compared to GCM projections, our results show stronger increases in spring and early summer precipitation, potentially from the extra evaporation over lakes. This trend especially manifests in heavier precipitation events. Precipitation is expected to decrease during the peak growing season in middle and late summer. We anticipate that temperature and precipitation values will be significantly different by the middle and end of the 21st century, respectively, from what has been observed at the beginning of the 21st century. Winters and summers are expected to be up to 7 and 4°C warmer, respectively, especially over northern and central Minnesota. Average spring precipitation may increase by more than 1 mm d−1 over central Minnesota. Despite generally stronger precipitation, winter snow depth is projected to decrease by more than 12 cm, especially around the Lake Superior shores and in northern Minnesota. Lake ice cover is projected to decrease by more than half over deeper lakes. The number of lake ice days per year and days per year with snow depth of more than 2.54 cm may decrease by up to 70 and 55, respectively.

    Earthworm biomass, soil temperature, bulk density, organic matter, pH, and leaf litter data from jumping worm and European earthworm-invaded forests at the Minnesota Landscape Arboretum, 2020–2022
    (2026-03-10) Yoo, Kyungsoo; Baumann, Tyler; Frelich, Lee; Buchholz, Erin; Wang, Shuai; kyoo@umn.edu; Yoo, Kyungsoo
    This dataset accompanies a study on the invasion of Asian jumping worms (Amynthas spp.) into hardwood forests previously infested with European earthworms (Lumbricus spp.) at the Minnesota Landscape Arboretum. The manuscript is current in revision (Baumann, T.T., Frelich, L., Buchholz, E., Wang, S., and Yoo, K. Jumping worm invasion in a European earthworm-infested hardwood forest in Minnesota: population surveys and soil changes. Ecosphere. In Revision.) The dataset includes: (1) earthworm population surveys identifying species composition and biomass across three sugar maple forests, with sampling points classified as Amynthas-dominated (A-sites), Lumbricus-dominated (L-sites), or transitional (T-sites); (2) soil physical and chemical properties including bulk density, soil organic matter, and pH measured at three depth intervals (0-5, 5-10, 10-15 cm); (3) seasonal leaf litter dry mass measurements; (4) continuous soil temperature records from iButton sensors at multiple depths; and (5) GPS coordinates for all sampling locations. Data were collected during 2020-2022.

    Queering the Third Place: Designing Campus Spaces for Transgender Students
    (2026) Shilman, Lucas;
    The design of current third places that serve as social places for transgender undergraduate students at the University of Minnesota can play a significant role in the sense of community and social solidarity they foster as third places. This thesis studies how campus queer and trans places at the University of Minnesota Twin Cities are designed to serve the transgender student community and evaluates the effectiveness of each place in creating a welcoming and accommodating environment. Data has been collected through interior spatial analysis of each site and observation. Additional information was gathered through interviews with four different professionals that work in a university setting. This data was used to understand what role the design and policy of third places—whether physical or digital—have on the perceived inclusiveness and accommodation of transgender students. This study found that third places that have a less sterile feeling environment create a greater sense of belonging and comfort within an occupiable place. It also found that ensuring the physical necessities of communities (such as all-gender restrooms) that occupy the place are met within a reasonable distance of the third place. With the understanding gained from this study, a concrete list of proposals to make current campus third places more inclusive of transgender students is proposed as well as a call to create a set of guidelines that can be used to create future spaces that support inclusivity of not only transgender students, but all marginalized identities.

    Knowledge Clusters and Entrepreneurship in Regional Economic Development
    (Humphrey School of Public Affairs, 2004) Munnich, Lee; Brush , Paul; Schuh, G. Edward; Keeley, Kevin; Sullivan, Colbey; Enerson, Marit; Templin, Elizabeth; Slipek, Deb Miller; La Plante, John; Grimes, Sharon; Streitz, Julie; Lund, Julie
    The conference on Knowledge Clusters and Entrepreneurship in Regional Economic Development was held at the Hubert H. Humphrey Institute of Public Affairs at the University of Minnesota in Minneapolis on September 13 and 14, 2004. The conference was staged by the Humphrey Institute’s State and Local Policy Program, the Carlson School of Management’s Center for Entrepreneurial Studies, and the Freeman Center for International Economic Policy, with support from the US-UK Fulbright Commission, the United States Department of Agriculture, Invest Northern Ireland, the Northern Ireland Bureau, and the University of Minnesota Extension Service. The concept for the conference was developed by Senior Fellow Lee Munnich and Fulbright Fellow Paul Brush, with an eye toward seeking an intersection between Munnich’s research on knowledge clusters and regional economic development and Brush’s research on entrepreneurship in both the United States and in his native Northern Ireland. The conference itself brought together academics and practitioners from both sides of the Atlantic to examine the relationship between clusters, entrepreneurship, and economic development strategies. The conference stimulated intense dialogue around innovative approaches to regional economic development, and led to the creation of this report. This report seeks to provide a synthesis of the concepts and insights discussed and developed at the conference, while also providing practitioners with tangible, actionable ideas for integrating cluster, entrepreneurship, and economic development strategies. We hope that academics and practitioners alike will find this report to be accessible, enlightening, and useful in their work and in their research.
