    10.5 T CRT-MRSI metabolic, spectral and quality maps
    (2024-10-01) Marjanska, Malgorzata; Bogner, Wolfgang; Hingerl, Lukas; Strasser, Bernhard; gosia@umn.edu; Marjanska, Malgorzata; University of Minnesota, Center for Magnetic Resonance Research
    Magnetic resonance spectroscopy data measured from a brain of a healthy volunteer at 10. 5 tesla. These data show the metabolic maps, CRLB maps and LCModel fits, input data and fitted baseline in nifti-format. The volunteer was measured three different resolutions (4.40 mm³ isotropic, 3.44 mm³ isotropic, and 2.75 mm³ isotropic) using a concentric ring trajectory (CRT) FID-based sequence, reconstructed using a discrete Fourier transform, and fitted with LCModel (for more details, see below). The metabolic maps are in auxilliary units (a.u.) and are not in physical units. All these files can be viewed with freeview of freesurfer 7.1.1. It is being released to allow researchers to fully appreciate these 3D datasets, which are hard to otherwise visualize.

    1862 in Dakota Land, a Genocide Forgotten: How civilizational transformation can get lost in the fading rate of history
    (2008-06-26) Andregg, Michael M.
    1862 was a critical year in a process by which a land larger than many nations was transformed from one civilization to another. But the process was not a classic conquest easily marked in history books. Rather, it was a slower ‘digestion’ of over 20 million hectares of territory by one civilization accompanied by moments of true genocide or at least “ethnic cleansing” amidst much longer periods of very high death rates for one group and high birth rates and especially immigration rates for the other group. But this was sufficiently gradual that most historians did not record it on their lists of wars and other organized conflicts. I will discuss some extremely divergent views on what happened then. One reason they are so divergent is because the conflict of 1862 and its aftermath were extremely complex, with massacres on both sides, and with Indians working on both sides. Some whites fought to exterminate the Indians while others risked their lives to save them, and vice versa. Half-breeds of many kinds were caught in the middle, trying to survive a dramatic civilizational transformation that was occurring all around them. The result: In 1800, the territory now called Minnesota was 99%+ Indian, and by 1900 it was 99%+ whites of European descent.

    2003 Rock Properties Database: Density, Magnetic Susceptibility, and Natural Remanent Magnetization of Rocks in Minnesota
    (Minnesota Geological Survey, 2010-08-06) Chandler, V.W; Lively, R.S; mgs@umn.edu; Minnesota Geological Survey
    Geologic interpretation of gravity and magnetic anomaly data in a given area is greatly enhanced if density, magnetic susceptibility and natural remanent magnetization (NRM) data are available for representative rock-types. Along with outcrop and drill-hole information, rock property data help relate geophysical anomaly signatures to probable rock types, and provide constraints on the use of anomaly data as a tool for mapping and for modeling geology at depth. Most of the density and magnetization data contained in this database were acquired over the last two decades by the Minnesota Geological Survey (MGS) as part of an on-going program to collect rock properties. A group of Paleozoic samples were collected from Iowa and included in the database because they provide a representative suite of data for rocks present, but not widely exposed in Minnesota. Additional data were derived from studies by the U. S. Geological Survey (Bath, 1962; Beck, 1970; Beck and Lindsley, 1969; Books, 1972; Jahren, 1965), The University of Minnesota (Bleifuss, 1952, Mooney and Bleifuss, 1952), The University of Western Ontario (Palmer, 1970), and the Geological Survey of Canada (Dubois, 1962).

    2015 Twin Cities Metropolitan Area Urban Tree Canopy Assessment
    (2017-01-03) Knight, Joe F; Rampi, Lian P; Host, Trevor K; jknight@umn.edu; Knight, Joseph, F
    A high-resolution (1-meter) tree canopy assessment was completed for the Twin Cities Metropolitan Area. Mapping of existing and potential tree canopy is critical for urban tree management at the landscape level. This classification was created from combined 2015 aerial imagery, LIDAR data, and ancillary thematic layers. These data sets were integrated using an Object-Based Image Analysis (OBIA) approach through multi-resolution image segmentation and an iterative set of classification commands in the form of customized rulesets. eCognition® Developer was used to develop the rulesets and produce raster classification products for TCMA. The results were evaluated using randomly placed and independent verified assessment points. The classification product was analyzed at regional scales to compare distributions of tree canopy spatially and at different resolutions. The combination of spectral data and LiDAR through an OBIA method helped to improve the overall accuracy results providing more aesthetically pleasing maps of tree canopy with highly accurate results.

    2021-2022 Greater Voyageurs Ecosystem wolf pack and population size report
    (2022) Gable, Thomas D; Homkes, Austin T; Bump, Joseph K
    This report presents and discusses data on wolf population metrics collected during 2021-2022 in the Greater Voyageur Ecosystem, Minnesota. In 2021-2022, we estimated the area of 9 wolf pack home ranges/territories, determined the size of 14 wolf packs, and obtained 7.3 independent observations of the same size for each pack. The survey effort in 2021-2022 was the same as 2020-2021 and represents the most intensive survey effort, in terms of number of packs and territories studied, to date in the Greater Voyageurs Ecosystem. We estimate that wolf population density in the Greater Voyageurs Ecosystem in 2021-2022 was 63.2 wolves/1000 km2 (95% confidence interval: 50.3-83.8 wolves/1000 km2). This density represents a 16% increase in population density from 2020-2021 and a 48% increase from the recent population low in 2019-2020 of 42.7 wolves/1000 km2. The increase in population density is largely attributable to increased pup survival, which likely increased pack size. We compared current wolf population density and population metrics to historical wolf density and population metrics in the Greater Voyageurs Ecosystem. This assessment suggests that wolf density in the GVE has changed little since the late 1980's, and that the GVE has sustained a high-density wolf population for decades.

    2022 Midwest broccoli trial results
    (2023-01-26) Hoidal, Natalie; Rohwer, Charlie; Enjalbert, Nico
    Disease pressure and climate change pose significant challenges to growing broccoli in the Midwest. Since around 2018, the pathogens black rot (Xanthamonas campestris pv. campestris) and Alternaria (Alternaria spp.) have become common on farms and in gardens, with some growers reporting 80-100% yield losses. Especially for organic growers, varietal tolerance can be a powerful tool for disease management. We conducted replicated broccoli trials at the Southern Research and Outreach Center (SROC) in Waseca, Minnesota, where we inoculated plots with black rot (Xanthamonas campestris pv. campestris). We also partnered with 88 farmers and gardeners to conduct mini trials at their farms and gardens. Our goal was to screen for varieties of broccoli with tolerance to the pathogens black rot and Alternaria, as well as environmental challenges like warm fall nights and high heat in the summer. This report outlines the results of the 2022 trial with overall takeaways and variety recommendations from both 2021 and 2022.

    2022 SMBSC--Management of Rhizoctonia Diseases in Sugarbeet
    (2022) Chanda, Ashok
    Rhizoctonia seedling damping-off and root rot diseases are prevalent in southern Minnesota sugarbeet growing areas. Utilization of soybeans and corn as rotation crops with sugarbeet will increase the risk for Rhizoctonia diseases and ultimately cause significant yield loss and loss of revenue to the sugarbeet growers. This presentation covers various strategies that were tested under field conditions in 2021 and previous years at the Northwest Research and Outreach Center, Crookston, MN. Rhizoctonia mitigation techniques included in this presentation are useful to successfully manage Rhizoctonia diseases in southern Minnesota growing area.
