Species Status Assessments provide vital information to US Fish and Wildlife for improving considerations for climate change impacts. In the constrained timeline of species listing decisions, it is not always feasible to conduct lengthy quantitative analyses so there is a need for better resources to provide input for rapid decision-making. In this project, the team will work with species status assessment teams to address direct and indirect effects of climate change on priority species chosen through conversations with US Fish and Wildlife regional offices. This project aims to provide an overview of the direct and indirect effects of climate change on species life cycle, survival, species interactions, and habitat...

Manoomin, or wild rice, is an essential, sacred species for Native people throughout the Upper Great Lakes region, who have relied on the plant for food and ceremony for hundreds of years. Manoomin is also important to non-Native people, who also harvest it and benefit from the wildlife sustained by it. Manoomin is an indicator of ecosystem health—if manoomin is healthy so is the surrounding ecosystem. Unfortunately, this aquatic grass has declined across much of its range due to multiple human-caused stressors, including changes to water levels in the lakes and streams in which manoomin grows. Climate change will further disrupt water levels, most directly through changes in precipitation, but also through climate-driven...

Moose are an economically and culturally important species in Minnesota. Like many species, however, moose are experiencing reductions in distribution and abundance across the Midwest as a result of climate change and habitat loss. Moose populations have declined by 60% since 2006, in part because of thermal heat stress in warming summers and increased frequency of contact with white-tailed deer that transmit fatal parasites. Forest managers are looking for actionable strategies to improve moose habitat in the near-term while also planning for future forest conditions in a warming climate. To address this need, this project brings together researchers and managers to examine how climate adaptive forest management...

Global concern of an “insect apocalypse” is fueling demand for large-scale, long-term studies of insect population dynamics. Butterflies associated with open habitat, like prairies and grasslands, have long been identified as species of concern in the Midwest. The iconic monarch butterfly, which serves as a flagship for both migration and insect conservation, is one such species of conservation concern and is currently under consideration for federal listing under the Endangered Species Act. Recent analyses suggest that common, widespread species may also be declining. Yet robust evidence for general declines is patchy and the causes are difficult to discern. Understanding the relative importance of climate, land...
Mounting evidence shows overall insect abundances are in decline globally. Habitat loss, climate change, and pesticides have all been implicated, but their relative effects have never been evaluated in a comprehensive large-scale study. We harmonized 17 years of land use, climate, multiple classes of pesticides, and butterfly survey data across 81 counties in five states in the US Midwest. We find community-wide declines in total butterfly abundance and species richness to be most strongly associated with insecticides in general, and for butterfly species richness the use of neonicotinoid-treated seeds in particular. This included the abundance of the migratory monarch (Danaus plexippus), whose decline is the focus...

Our aim was to describe shifts in autumn and winter harvest distributions of three species of dabbling ducks (blue-winged teal [Spatula discors], mallard [Anas platyrhynchos], and northern pintail [Anas acuta]) in the Central and Mississippi flyways of North America during 1960–2019. We measured shifts in band recovery distributions corrected for changes in hunting season dates and zones by using kernel density estimators to calculate 10 distributional metrics. We then assessed interannual and intraspecific variation by comparing species-specific changes in distributional metrics for 4 months (October–January) and three geographically based subpopulations. During 1960–2019, band recovery distributions shifted west-...

Walleye (Sander vitreus) and Yellow Perch (Perca flavescens) are culturally, economically, and ecologically significant fish species in North America that are affected by drivers of global change. Here, we review and synthesize the published literature documenting the effects of ecosystem changes on Walleye and Yellow Perch. We focus on four drivers: climate (including temperature and precipitation), aquatic invasive species, land use and nutrient loading, and water clarity. We identified 1232 tests from 370 papers, split evenly between Walleye (N=613) and Yellow Perch (N=620). Climate was the most frequently studied driver (N=572) and growth/condition was the most frequently studied response (N=297). The most commonly...

Under shifting temperatures and precipitation patterns, Midwestern states are increasingly at risk from non-native invasive plants that are changing the composition, structure, and function of native forests. Non-native invasive plants impact the resilience and sustainability of forest communities by outcompeting native tree seedlings and diverse flowering plants, and by altering ecologically important patterns of natural processes like fire, wind, drought, and flooding. Land managers facing this threat are having to not only consider current non-native invasive plants within their landscapes but also future impacts with the expansion of these plants northward and westward under a changing climate, especially as...
