    Data in Support of Predicting climate change impacts on poikilotherms using physiologically guided species abundance models
    (2022-07-14) Schliep, Erin M; North, Joshua S; Kundel, Holly; Custer, Christopher A; Ruzich, Jenna K; Hansen, Gretchen J A; ghansen@umn.edu; Hansen, Gretchen J A; University of Minnesota Dr. Hansen Research Team
    Fish catch and effort data for three species caught in gill nets and trap nets between 1988 and 2019 as part of Minnesota Department of Natural Resources (MNDNR) fisheries surveys conducted during the summer and early fall are included from over 1,300 Minnesota lakes. The three fish species included are: bluegill (Lepomis marochirus) a warm-water adapted species, yellow perch (Perca flavescens) a cool-water adapted species, and cisco (Coregonus artedi) a cold-water adapted species. Additional data concerning lake characteristics and surrounding land cover were also included. Mean July lake surface temperature was calculated using simulated daily water temperatures. Watershed land use including agricultural, barren, forest, grass, shrub, urban, and wetland cover, was determined using the 2016 National Land Cover Database. Secchi, a measure of water clarity was calculated from remotely sensed Secchi depth courtesy of Max Glines. Lastly, lake area and maximum depth were obtained from MNDNR public databases.

    Invasive Eurasian watermilfoil data from Minnesota lake point-intercept surveys between 1995 and 2019
    (2021-08-03) Thomas, Shyam; thom7552@umn.edu; Thomas, Shyam; Hansen and Larkin labs, Department of Fisheries, Wildlife & Conservation Biology, University of Minnesota
    The datasets uploaded describe Eurasian watermilfoil distribution and abundance across the state of Minnesota. The dataset formed the basis for all the analyses in the paper referenced below.
