title: Vegetation classification crosswalk database for use in GIS to synchronize vegetation map layers of the NPS Great Lakes Network to the U.S. National Vegetation Classification

description: The geodatabase contains 13 relate tables that together provide updated and synchronized classifications to an existing vegetation map layer for each of the nine park units in the Great Lakes Network (GLKN) of the National Park Service (NPS) Natural Resource Inventory and Monitoring Program. The classifications include 1) vegetation types at every hierarchical level in the 2015 version of the U.S. National Vegetation Classification (USNVC) and 2) map classes that represent vegetation and land cover in the vegetation map layers. Furthermore, the tables provide a crosswalk between the two classifications (vegetation and map). Each park unit in GLKN has received, at different times over several years, vegetation data products from the NPS Vegetation Mapping Inventory (VMI) Program. However, the vegetation and map classifications were at different stages of development over these years. With this geodatabase product, having a series of already linked relate tables, the original vegetation map layer for each park unit can be linked to the updated and synchronized classification information for both vegetation types and map classes.

title: Data and Code for: COVID-19 Disruptions Disproportionately Affect Female Academics

description: The rapid spread of the COVID-19 pandemic and subsequent countermeasures, such as school closures, the shift to working from home, and social distancing are disrupting economic activity around the world. As with other major economic shocks, there are winners and losers, leading to increased inequality across certain groups. In this project, we investigate the effects of COVID-19 disruptions on the gender gap in academia. We administer a global survey to a broad range of academics across various disciplines to collect nuanced data on the respondents’ circumstances, such as a spouse’s employment, the number and ages of children, and time use. We find that female academics, particularly those who have children, report a disproportionate reduction in time dedicated to research relative to what comparable men and women without children experience. Both men and women report substantial increases in childcare and housework burdens, but women experienced significantly larger increases than men did.

description: The rapid spread of the COVID-19 pandemic and subsequent countermeasures, such as school closures, the shift to working from home, and social distancing are disrupting economic activity around the world. As with other major economic shocks, there are winners and losers, leading to increased inequality across certain groups. In this project, researchers investigated the effects of COVID-19 disruptions on the gender gap in academia. They administered a global survey to a broad range of academics across various disciplines to collect nuanced data on the respondents' circumstances, such as a spouse's employment, the number and ages of children, and time use.
description: The purpose of this study was to test if the disproportionate productivity slowdown among female scholars since the onset of the pandemic would be due to the disproportionate childcare burden falling upon women amid school and daycare closures. Researchers analyzed survey evidence pertaining to the use of time by academic researchers before and after the disruptions caused by COVID-19.
description: Researchers sent a survey via email to approximately 900,000 individuals who had published at least one academic article in the past five years. The distribution window, including two follow-up reminders, ran from May 27, 2020 to July 21, 2020, yielding a total of 27,991 responses.
description: Variables include questions about the amount of hours spent weekly on various work related and personal activities and how COVID affected work and personal activities. Demographic variables include age, number of children, gender, and European Economic Area residency.

title: 2000 UMRS Land Cover Land Use

description: The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) is in the process of creating high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:24,000-scale color infrared aerial photos collected in 2000. The photos are being interpreted using a 1-hectare 10% minimum vegetation cover to delineate land cover/land use, percent vegetation cover, tree height, and hydrology regime. The geographic extent of the UMRS is the Mississippi River from Cairo, IL to Minneapolis, MN and the Illinois River from its confluence with the Mississippi near Grafton, IL to Lake Michigan.

title: Rotifera in Lake Pepin in the Upper Mississippi River from 2012 to 2015: Data

description: Limited information is known regarding the rotifer community on the Upper Mississippi River (UMR). Studies have shown that rotifers are a common prey for invasive bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix) as well as native fishes of the UMR and there is concern these invasive carp will compete with native fishes for food resources. This study was conducted to provide baseline rotifer community data before range expansion of these invasive carps into the upper reaches of the UMR. Vertical tows were taken to collect rotifer samples over a four year period in Lake Pepin, a natural riverine lake in Pool 4 of the UMR. Four dominant genera (Keratella, Polyarthra, Trichocerca and Brachionus) comprised the samples and significant correlations between rotifer abundance and temperature, volatile suspended solids and chlorophyll-a were observed. Our results identify potential drivers of rotifer abundance and provide robust rotifer abundance and composition data. These pre-invasion data are critical to recognizing the effects invasive carp have on zooplankton communities and the UMR ecosystem.

title: Using a gradient in food quality to infer drivers of fatty acid content in two filter-feeding aquatic consumers:Data

description: Inferences about ecological structure and function are often made using elemental or macromolecular tracers of food web structure. For example, inferences about food chain length are often made using stable isotope ratios of top predators and consumer food sources are often inferred from both stable isotopes and fatty acid (FA) content in consumer tissues. The use of FAs as tracers implies some degree of macromolecular conservation across trophic interactions, but many FAs are critically important for particular physiological functions and animals may selectively retain or extract these critical FAs from food resources. Here, we compared spatial variation in two taxa that feed on the same (or similar) food resources to assess which FAs appear to be responding to a common gradient in food resources. Filter feeding caddisflies (Family Hydropyschidae) and dreissenid mussels (Genus Dreissena) both consume seston, and had similar spatial variation in stable isotopes (C and N) across 13 sites in the Great Lakes region of North America. Only one of forty-one FAs measured showed strong spatial co-variance in these taxa (&amp;amp;#945;-linolenic acid; ALA), indicating other FAs are responding to other environmental gradients in at least one of these taxa. Based on other experimental studies, ALA does appear to be driven by food availability in caddisflies, so it seems likely that ALA spatial co-variance reflects spatial variation in this food resource in this study. We conclude that inferences made using FAs as tracers of food web structure may be very sensitive to the individual taxa studied.

title: UMRR Tier 2 Lidar Data for the Upper Mississippi and Illinois RIvers

description: Light Detection And Ranging (Lidar) generates extremely accurate (vertical and horizontal) location information and has long been a desired product for the UMRS. Previously, the best publically available elevation data for the entire UMRS is 30 meter cells, though 10 meter/cell data can now be downloaded for many areas. In 2007, the U.S Army Corps of Engineers� Upper Mississippi River Restoration Program (UMRR) partnered with the Iowa Department of Natural Resources (IDNR) to collect FEMA-grade, bluff-to-bluff lidar for Navigation Pools 8-24 of the UMRS. In 2009, with American Recovery and Reinvestment (ARRA) funds awarded to UMRR, the remaining lidar for the Upper Mississippi River, to the confluence with the Ohio River, and the Illinois River was contracted. Data acquisition was completed in 2011. Lidar data are remotely sensed, high-resolution elevation data collected by airplane. The Upper Midwest Environmental Sciences Center is processing these data to create Digital Elevation Models (DEMs), 0.5 meter contour lines, and pool-wide hillshade images. The collection and processing of these data are funded by the U.S. Army Corps of Engineers� UMRR-EMP.

title: Indiana Bat Project data

description: Our model is a full-annual-cycle population model {hostetler2015full} that tracks groups of bat surviving through four seasons: breeding season/summer, fall migration, non-breeding/winter, and spring migration. Our state variables are groups of bats that use a specific maternity colony/breeding site and hibernaculum/non-breeding site. Bats are also accounted for by life stages (juveniles/first-year breeders versus adults) and seasonal habitats (breeding versus non-breeding) during each year, This leads to four states variable (here depicted in vector notation): the population of juveniles during the non-breeding season, the population of adults during the non-breeding season, the population of juveniles during the breeding season, [...]

title: Evidence of Asian carp spawning above a key choke point in the Mississippi River: Data

description: Bighead Carp, Silver Carp and Grass Carp (collectively Asian carp) were introduced to North America in the 1960s and 70s and have established in the lower Mississippi River basin. Previously published evidence for spawning of these species has been limited in the upper Mississippi River to just downstream of Dam 22 (near Saverton, MO). In 2013 and 2014, we sampled ichthyoplankton at 18 locations in the main stem of the upper Mississippi River from Dam 9 through Dam 19 and in four tributary rivers that empty into the Mississippi River (Des Moines, Skunk, Iowa and Wisconsin Rivers). We identified eggs and larvae using morphological techniques and then used genetic tools to confirm species identity. The spawning events we observed often included more than one species of Asian carp and in a few cases included eggs that must have been derived from more than one upstream spawning event. The upstream extent of genetically confirmed Grass Carp ichthyoplankton was in the Wisconsin River, while Bighead Carp and Silver Carp ichthyoplankton were observed in Pool 16 of the Mississippi River. In all these cases, ichthyoplankton likely drifted downstream for several kilometers prior to collection. Higher water velocities (and to a lesser extent higher temperatures) were associated with increased likelihood of observing eggs or larvae, although the temperature range we encountered was mostly above 17&amp;amp;deg;C. Several major spawning events were observed in 2013, but not in 2014. The area between dams 15 and 19 appears to be the upstream edge of spawning activity for both Silver Carp and Bighead Carp, suggesting this area could be a focal point for management designed to limit further movement of these species upstream. &amp;amp;amp;#8195;

title: WKBT Soils and Floodplain Nutrients

description: We examined effects of flooding on supply rates of 14 nutrients in floodplain areas invaded by Phalaris arundinacea (reed canarygrass), areas restored to young successional forests (browsed by white-tailed deer and unbrowsed), and remnant mature forests in the Upper Mississippi River floodplain. Plant Root Simulator ion-exchange probes were deployed for four separate 28-day periods. The first deployment occurred during flooded conditions, while the three subsequent deployments were conducted during progressively drier periods. Time after flooding corresponded with increases in NO3--N, K+ and Zn+2, decreases in H2PO4--P, Fe+3, Mn+2, and B(OH)4-B, a decrease followed by an increase in NH4+-N, Ca+2, Mg+2 and Al+3, and an increase followed by a decrease for SO4-2-S. Plant community type had weak to no effects on nutrient supply rates compared to the stronger effects of flooding duration. Our results suggest that seasonal dynamics in floodplain nutrient availability are similarly driven by flood pulses in different community types. However, reed canarygrass invasion has potential to increase availability of some nutrients, while restoration of forest cover may promote recovery of nutrient availability to that observed in reference mature forests.

title: 1989 Land Cover/Use Data for the Upper Mississippi River System

description: The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:15,000-scale color infrared aerial photos collected in 1989. The data are available in two formats. The first used a detailed genus-level classification scheme and was used to classify Mississippi River Navigation Pools 4 through 26, the Open River between Grand Tower and River Mile 32, and the Peoria navigation Pool on the Illinois River. The second classification scheme was developed in 1998 in response to a scientific and programmatic review of the center's mapping projects. This classification scheme identifies plant communities and associations. This second classification scheme was used to interpret data for Mississippi River Pools 1 through 3, the Open River between Lock and Dam 26 and Grand Tower, and the Alton, Starved Rock, Marseilles, Brandon, Dresden, and Lockport navigation pools on the Illinois River. At the time this metadata document was prepared data classified underneath the first classification scheme were being cross-walked to the new scheme. This metadata document has been prepared to document the second classification scheme.

title: Lethal and sub-lethal responses of native freshwater mussels exposed to granular Bayluscide&amp;reg;, a sea lamprey larvicide: Data

description: The invasive sea lamprey poses a substantial threat to fish communities in the Great Lakes. Efforts to control sea lamprey populations typically involve treating tributary streams with lampricides on a recurring cycle. Elevated densities of sea lampreys in the aquatic corridor between Lakes Huron and Erie prompted managers to propose a treatment using Bayluscide&amp;reg;�a granular lampricide formulation that targets larval sea lamprey that reside in sediments. However, there was concern over the potential for adverse effects of this treatment on native freshwater mussels�imperiled animals that also reside in sediments. We estimated the risk of mortality and sub-lethal effects among eight species of adult and sub-adult mussels exposed to Bayluscide&amp;reg; for durations up to 8 hours to mimic field applications. At one of 12 time periods (0, 15, 30, 45, 60, 75, 90, 105, 120, 240, 360, or 480 min), one mussel from each aquarium was randomly removed, assessed for response variables (see below) and placed into a recovery raceway for 21 days. Response variables were: depth of burial into substrate, siphoning activity, dead or alive, and foot extension beyond shell margin.

title: Tree Species Preferences of Foraging Songbirds During Spring Migration in Floodplain Forests of the Upper Mississippi River: data

description: We evaluated bird foraging preferences for tree species during spring migration 2010-2013. We used the point center-quarter method to assess relative availability (tree importance values, IV) of tree species and tallied bird foraging observations on tree species as well as recording the phenophase of used trees on five 40 ha plots of contiguous floodplain forest between La Crosse, Wisconsin, and New Albin, Iowa, from 15 April through 1 June 2010-2013. We quantified bird preferences by comparing proportional use of tree species by each bird species to estimates of tree species availability (IV) for all four years and for each year separately. Bird data records contain the plot identity, date, time of the observation, species of bird, sex if distinguishable, tree species in which it was foraging, location the bird was in the tree, dbh of the tree, phonological phase of the tree and any comments about the observation (foraging in flowers, if tree was in flower, etc.)

title: Sediment-contaminant Database for the Upper Mississippi River System (Version 2)

description: The Sediment-Contaminant Database for the Upper Mississippi River System contains information from a total of 3950 analyzed sediment samples, including 2697 from the Mississippi River, 440 from the Illinois River, and 813 from tributaries. These samples were collected during 1974 through 2000, with 262 samples from the 1970s, 2168 from the 1980s, 1518 from the 1990s, and 2 from the year 2000. The database contains data on metals, metalloids, nutrients, polynuclear aromatic hydrocarbons, insecticides, herbicides, fungicides, industrial compounds, sterols, petroleum-related compounds, and polychlorinated biphenyls in three types of samples: bed sediment (86.6% of the samples), sediment trap (1.8%), and pore water (11.6%). The relative completeness of quality-assurance documentation for each of 44 discreet data sets entered was characterized by a quality-assurance index. To facilitate interpretation, the database provides information on sampling locations. Methods of sample collection, physical characteristics of analyzed sediment, and other ancillary variables for each sample. The database is available on CD-ROM or through the Internet. The overall goal was to create a comprehensive database with data of known quality that would be readily available to interested users, to facilitate the assessment of riverine contamination, to increase the availability of historic sediment-contaminant data, and to facilitate management and scientific efforts pertaining to contaminated-sediment issues in the river system.
