(2022-03-04) Haight, Robert, G.; Yemshanov, Denys; Kao, Szu-Yu; Phelps, Nicholas B. D.; Kinsley, Amy, C; robert.haight@usda.gov; Haight, Robert, G.; Minnesota Aquatic Invasive Species Research Center (MAISRC); University of Minnesota, School of Public Health; Department of Veterinary Population Medicine; Canadian Forest Service, Great Lakes Forestry Centre, Sault Ste. Marie, Ontario, Canada; USDA Forest Service, Northern Research Station, St. Paul, MN, USA
These data contain a bi-level model for determining how a state planner can efficiently allocate inspection resources to county managers, who independently decide where to locate inspection stations. We apply the model to a hypothetical allocation problem for the state of Minnesota. The model includes the infestation status of 9,182 lakes, of which 471 are infested with zebra mussel, starry stonewort, or Eurasian watermilfoil, and estimates of annual numbers of high-risk boat movements from infested to uninfested lakes.
Bythotrephes lake abundances and gear ensnarement abundances on Island Lake and Lake Mille Lacs, Minnesota, in 2017 and 2018
(2022-07-14) Branstrator, Donn K; Brady, Valerie J; dbranstr@d.umn.edu; Branstrator, Donn K; University of Minnesota Duluth and NRRI
The repository contains two Excel data files, one based on samples collected from Island Lake Reservoir (Duluth MN) in 2017 (filename: IslandSpiny2017) and the other collected from Lake Mille Lacs (Garrison MN) in 2018 (filename: MilleLacsSpiny2018). Large portions of the analyzed data were first published in the referenced journal article. This article should be read for an overview of the locations where samples were collected and the nature of the data. Briefly, the data are measurements of the numbers and characteristics of spiny water flea (Bythotrephes) ensnared on various types of angling gear and the numbers and characteristics of spiny water flea collected by net tows at the locations and times that the angling gear types were deployed.
Carp Edema Virus Host Range Study in Lake Swartout and Outbreaks in four other lakes
(2021-03-02) Tolo, Isaiah; Phelps, Nicholas B. D.; tolo0007@umn.edu; Phelps, Nicholas; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Mass mortality events of common carp (Cyprinus carpio, carp) associated with carp edema virus (CEV) alone or in coinfections with koi herpesvirus (KHV), is an emerging issue. Despite recent outbreaks of CEV in wild carp populations, the host range of North American species has not been well studied. To that end, we intensively sampled carp (n = 106) and co-habiting native fish species (n = 5 species; n = 156 total fish) from a CEV-suspect mass-mortality event of carp in a small Minnesota lake (Lake Swartout). Additionally, fecal and regurgitant samples (n = 73 each) from double-crested cormorants (Phalacrocorax auritus, DCCO) were sampled to test the potential of DCCO to act as a vector for virus transmission. CEV was confirmed to be widespread in the Lake Swartout carp population during the outbreak with high viral loads and histological confirmation, suggesting that CEV was the cause of the mortality event. There were no detections of CEV in any native fish species; however, DCCO regurgitant and fecal samples were positive for CEV DNA. In addition, three CEV-positive and one CEV+KHV-positive mortality events were confirmed with no observed mortality or morbidity of non-carp species in other lakes. This study provides evidence that CEV infection and disease may be specific to carp during mortality events with mixed-species populations, identifies DCCO as a potential vector for CEV, and further expands the known range of CEV, as well as coinfections with KHV, in North America.

(2023-03-09) Culotta, Jackie; Vetter, Brooke, J; Mensinger, Allen, F; Kramer, Cassandra, A; Ervin, Marie, L; culot007@d.umn.edu; Culotta, Jackie; Laboratory of Dr. Allen Mensinger
Dissolved carbon dioxide avoidance in silver and bighead carps. Additionally, carp were conditioned to associate broadband sound from outboard boat motors (0.06 – 10 kHz, ~150 dB re 1 μPa) with CO2 application (~35,000 ppm). Phonotaxis trials were conducted over one to four weeks in a both a small (80 L) and large (3475 L) two-choice shuttle tank.
Complete Data and Analysis for: Constraining invader dominance: Effects of repeated herbicidal management and environmental factors on curlyleaf pondweed dynamics in 50 Minnesota lakes
(2020-01-08) Verhoeven, Michael R; Larkin, Daniel J; Newman, Raymond M; michael.verhoeven.mrv@gmail.com; Verhoeven, Michael R; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Curlyleaf pondweed (Potamogeton crispus) is one of the most widespread and widely managed aquatic invasive plants in North America. Despite decades of management, the efficacy of long-term management strategies and the effects of environmental drivers on curlyleaf pondweed populations remain uncertain. To evaluate the effects of management and environmental factors on within-lake distribution and local density of curlyleaf pondweed, we collated monitoring data from aquatic plant point-intercept surveys collected by a variety of lake managers across Minnesota, USA. The goal of the study was to examine the influence of herbicide treatment, water clarity, snow depth, and ice cover duration on curlyleaf pondweed distribution and density between 2006 and 2015. The data included in this repository includes the complete dataset as a comma-separated-value file and all Program R code necessary to replicate the data processing, analysis, and visualizations used in the study.

Complete Data and Analysis for: Niche models differentiate potential impacts of two aquatic invasive plant species on native macrophytes
(2021-01-22) Verhoeven, Michael R.; Glisson, Wesley J.; Larkin, Daniel J.; michael.verhoeven.mrv@gmail.com; Verhoeven, Michael R; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The goal of our study was to elucidate the mechanisms by which two invasive aquatic plant species (Myriophyllum spicatum and Potamogeton crispus) interact with native plant communities in lakes in Minnesota, USA. We used an observational dataset of aquatic plant occurrences—and associated light availability, depth, and temperature—to construct probabilistic models of the ecological niches of 34 aquatic plant species. We then compared shared-ness of these niches between the two invasive aquatic plants and 32 native species to infer the degree of direct competitive interaction. This repository contains the complete dataset as a comma-separated-value file and Program R code necessary to replicate the data prep, exploration, analysis, and visualizations presented in the manuscript.
Complete data and code to generate datasets in: Occurrence and environmental data for aquatic plants of Minnesota from 1999-2018
(2024-07-15) Verhoeven, Michael; Larkin, Daniel J.; michael.verhoeven.mrv@gmail.com; Verhoeven, Michael; Minnesota Aquatic Invasive Species Research Center (MAISRC); Fisheries Systems Ecology Lab
A dataset (and multi-scale aggregations thereof) of point-level occurrences, relative abundances, and associated environmental data for macrophytes (freshwater plants) across Minnesota. The data encompass 3,194 surveys of 1,520 lakes and ponds performed over a 19-year timespan. A total of 372,091 points were sampled, across which 231 taxa were recorded. Macrophyte occurrence data and depth, as well as point-level relative-plant-abundance measures for a subset of surveys, were collated, cleaned, and joined to geospatial data and Secchi-depth measurements of water clarity, enabling light availability, a primary control on aquatic plant growth, to be estimated.
Complete data for Overwinter survival of Corbicula fluminea in a central Minnesota lake
(2021-11-01) Weber, Megan M; Cibulka, Daniel; mmweber@umn.edu; Weber, Megan M; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Corbicula fluminea is regarded as one of the most pervasive freshwater aquatic invasive species in the world. It has been widely cited to have a lower lethal temperature threshold of 2 degrees Celcius, which suggests the species would be unable to survive in Minnesota outside of areas of thermal refuge from sources such as power plant, water treatment facility, and other raw water user effluent). In August 2020 a volunteer participating in Starry Trek, an aquatic invasive species early detection event, recovered live C. fluminea from an inland Minnesota lake with no known thermal refuge (Briggs Lake, Sherburne County). This data set documents the distribution, overwinter survival, and size class structure of the population in Briggs Lake and observational data at a nearby lake (Big Lake, Sherburne County) where additional clams were discovered by a volunteer towards the end of the Briggs Lake project timeline. The data from this study are available here for public use.
Complete Data for: Desiccation tolerance of the invasive alga starry stonewort (Nitellopsis obtusa) as an indicator of overland spread risk
(2021-10-13) Glisson, Wesley J.; Wagner, Carli K.; Verhoeven, Michael R.; Muthukrishnan, Ranjan; Contreras-Rangel, Rafael; Larkin, Daniel J.; wjglisson@gmail.com; Glisson, Wesley, J; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The ability of invasive macrophytes to survive out of water, i.e., their desiccation tolerance, is an important indicator of capacity for spread to new waterbodies through overland transport. Invasion by the alga starry stonewort (Nitellopsis obtusa [Desv. in Loisel.] J. Groves; Characeae) in North America is likely driven via overland transport, but little is known regarding its ability to remain viable out of water. We conducted laboratory and outdoor experiments to evaluate desiccation tolerance of N. obtusa propagules, including single stem fragments, small and large clumps of fragments, and bulbils (asexual reproductive structures). Propagules were removed from water after 15 min to 5 d to identify desiccation thresholds. The data from these experiments are documented and available here for public availability and use.
Complete Data for: Laboratory evaluation of copper-based algaecides for control of the invasive macroalga starry stonewort (Nitellopsis obtusa)
(2022-05-23) Glisson, Wesley J; Contreras-Rangel, Rafael; Bishop, West M; Larkin, Daniel J; wjglisson@gmail.com; Glisson, Wesley J; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Nitellopsis obtusa ([Desvaux] J. Groves [1919]; Characeae), known as starry stonewort, is an invasive macroalga in Laurentian Great Lakes states and provinces in North America. Because of its potential negative impacts on native ecosystems and recreation, N. obtusa has become a high-priority target for management. However, there is a critical lack of foundational information on the efficacy of different algaecides, and concentrations thereof, for N. obtusa control. Additionally, control of N. obtusa bulbils—asexual reproductive structures that are the main pathway for the establishment of new plants—has proven difficult. We tested the efficacy of six commonly used copper-based algaecides, at a series of copper concentrations up to the maximum labeled rate, on N. obtusa thalli (photosynthetic aboveground tissues) and bulbils in controlled laboratory experiments. Bulbils were placed above and below sediment in separate experiments to evaluate whether sediment acted as a barrier to treatment. The data from these experiments are provided and documented here.

In addition, 403 samples have corresponding mercury data, based on laboratory analyses conducted by USGS (Tate et al. 2022).
Data and R code for analysis of walleye and yellow perch age-0 length in Minnesota's Large Lakes
(2019-12-10) Hansen, Gretchen J A; Bethke, Bethany J; Ahrenstorff, Tyler D; Dumke, Josh; Hirsch, Jodie; Kovalenko, Katya E; LeDuc, Jaime F; Maki, Ryan P; Rantala, Heidi M; ghansen@umn.edu; Hansen, Gretchen; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Invasive species represent a threat to aquatic ecosystems globally; however, impacts can be heterogenous across systems. Documented impacts of invasive zebra mussels (Dreissena polymorpha) and spiny water fleas (Bythotrephes cedarstroemi; hereafter Bythotrephes) on native fishes are variable and context dependent across locations and time periods. Here, we use a hierarchical Bayesian analysis of a 35-year dataset on two fish species from 9 lakes to demonstrate that early life growth of ecologically important fishes are influenced by these aquatic invasive species. Walleye (Sander vitreus) grew more slowly throughout their first year of life, and were on average 12 or 14% smaller at the end of their first summer following invasion by Bythotrephes or zebra mussels, respectively. Yellow perch (Perca flavescens) growth was less affected by invasion. Yellow perch on average grew more slowly in their first year of life following invasion by zebra mussels, although this effect was not statistically distinguishable from zero. Early life growth of both walleye and yellow perch was less tightly coupled to degree days in invaded systems, as demonstrated by increased variance surrounding the degree day-length relationship. Smaller first-year size is related to walleye survival and recruitment to later life stages and has important implications for lake food webs and fisheries management. Future research quantifying effects of zebra mussels and Bythotrephes on other population-level processes and across a wider gradient of lake types is needed to understand the mechanisms driving observed changes in walleye growth.
Data and R code to support: Estimating densities of zebra mussels (Dreissena polymorpha) in early invasions using distance sampling
(2019-01-18) Ferguson, Jake M; Fieberg, John R; McCartney, Michael A.; Blinick, Naomi S.; Schroeder, Leslie; jakeferg@umn.edu; Ferguson, Jake M; Minnesota Aquatic Invasive Species Research Center (MAISRC)
These files are the data and code needed to reproduce the analysis of the manuscript "Estimating densities of zebra mussels (Dreissena polymorpha) in early invasions using distance sampling". The data include spatial coordinates of transects used to survey for zebra mussels in Lake Sylvia and Lake Burgan in the summer of 2017, the counts of zebra mussels on each transect, and environmental covariates collected along transects and at each detection. We also provide the R code needed to process and analyze these data following the distance survey approach described in the manuscript. We provide code for a straightforward distance survey, which doesn't include any spatial covariate information, as well as a more computationally intensive analysis that does include spatial covariates.
Data and R-code for: “Integrating DNA fingerprinting of invasive watermilfoil strains into aquatic vegetation monitoring and assessment”
(2024-06-06) Gannon, Kathryn A; Newman, Raymond M; Thum, Ryan A; newma004@umn.edu; Newman, Raymond M; Minnesota Aquatic Invasive Species Research Center (MAISRC)
Invasive Eurasian watermilfoil (Myriophyllum spicatum L.) hybridizes with native northern watermilfoil (Myriophyllum sibiricum Komarov). Previous genetic studies have identified numerous distinct Eurasian and hybrid strains that can differ in their invasiveness (e.g., growth and potential for spread) and response to herbicides. To identify problematic or invasive strains of watermilfoil we assessed the response of different watermilfoil strains to aquatic vegetation management in eight Minnesota lakes over the course of 3 yr. Specifically, we looked for changes in strain composition of watermilfoil populations over time to identify strains of specific interest for further characterization of growth and herbicide response. Eurasian watermilfoil was collected from point intercept surveys (125 to 230 points at each waterbody) before and after herbicide treatments and generally twice per year over 3 years. Plants were idented to genotype using microsatellite markers and changes in genotype occurrence and frequency were assess for changes over time and in response to treatment. Additional details and methods are presented in Gannon et al. 2022.
Data for A small native predator reduces reproductive success of a large invasive fish as revealed by whole-lake experiments
(2022-01-10) Poole, Joshua R; Bajer, Przemyslaw G; bajer003@umn.edu; Bajer, Przemyslaw; Minnesota Aquatic Invasive Species Research Center (MAISRC)
The extent to which native fish communities might control the success of invasive fish has been of interest to ecologists, but it has been rarely addressed using experiments. We conducted an experiment in six small lakes in the Upper Mississippi Region to test the effects of a small native predator, bluegill sunfish (Lepomis macrochirus) on the recruitment of a large, invasive fish, the common carp (Cyprinus carpio). Bluegills are predominant throughout the region and were previously shown to consume carp eggs and larvae. We stocked both lakes at each of our 3 sites with adult carp (spawners) and one lake at each site with bluegills. We repeated the experiment at two of the three sites for two consecutive years. In each lake we assessed the abundance of post-larval carp one month after spawning (backpack electrofishing surveys) and at the end of the season (mark-recapture). For each site/year combination, catch rate of post-larval carp was typically an order of magnitude higher in control than bluegill lakes, but it often declined quickly over time. The abundance of end-of-seasonal juveniles was significantly higher (no 95% CI overlap) in control lakes than in bluegill lakes, except for one pair of lakes during one year when both the control and bluegill lake had similar, low abundance of end-of-season carp. Overall, our results support the hypothesis that common carp recruitment is substantially reduced in habitats dominated by bluegills. We also suggest our results may be applicable to other species, and that managers should explore how predation on early life stages may control other invasive species.
Data for Evaluation of a broadband sound projected from the gates of a navigation lock in the Mississippi River shows it to be a weak deterrent for common carp and unable to block passage
(2022-01-19) Riesgraf, Andrew T.; Finger, Jean S.; Zielinski, Daniel P.; Dennis III, Clark E.; Whitty, Jeff M.; Sorensen, Peter W.; soren003@umn.edu; Sorensen, Peter W.; Minnesota Aquatic Invasive Species Research Center (MAISRC)
There is an urgent need to block the passage of carp and other invasive fishes through navigational locks in large rivers. Although the broadband sound of an outboard motor has been shown to strongly repel three species of carp in laboratory flumes and to a lesser extent inside of a lock chamber, it has not yet been tested to see if it can stop carp from entering a lock. To test this possibility, we attached speakers to lock gates and played the sound of an outboard motor while measuring its efficacy by tracking free-ranging transplanted tagged common carp in its vicinity. Eight groups of 20 carp were tested while the sound system was turned on and off for 2 week periods. When the sound system was on, these carp spent approximately one-third less time in front of the gates than when it was off which when modeled by GLMM was shown to no greater than the effects of river discharge or temperature. Further, there was no indication that this sound blocked carp from entering and presumably passing through the lock. However, the number of times that tagged carp entered the lock was low even when the sound was off. A number of factors may have contributed to the limited efficacy of this deterrent system including the sound itself.
