Yellow perch and alewife are ecologically, economically, and culturally important fish species in Lake Michigan whose populations support recreational and commercial fisheries. However, both of these species’ populations have been in decline for over 20 years. This project seeks to understand the factors affecting variability in offspring survival of yellow perch and alewife in Lake Michigan in order to project survival under scenarios of future climate change. Like other fish species, yellow perch and alewives produce huge numbers of small offspring, but most die early in life. Small changes in survival at this early stage can have a strong impact on the number of fish that ultimately contribute to fisheries....

Stream fish are in peril from a changing climate, particularly for species with restricted distributions or populations on the southern edge of their range. For these fish, the opportunity to escape warming temperatures is limited by the network of stream channels accessible to them. To deal with temperatures beyond their physical capacity, fishes must move, adapt, or die. However, little is known for many of these species about their preferred temperatures, critical temperature limits, or capacity to adapt to or tolerate increasing temperatures. Researchers will measure the preferred temperatures and tolerance of two stream fish that are vulnerable to climate change: the Ozark Shiner and the Blacknose Shiner. The...

Inland fisheries have tremendous cultural, economic, and subsistence value. However, climate change brings new stresses to land-locked fisheries that raise novel challenges for resource managers. One fundamental challenge in inland fisheries is how to best assess and manage data-limited fisheries when resources are finite and uncertainty is pervasive. To address this challenge, we will use quantitative models to examine whether indicators of fish population status commonly-measured by managers can serve as a “short-cut” to more data- and capacity-intensive approaches. Further, we will work and communicate directly with state and Tribal fisheries managers to better understand the challenges they face when making...

Climate change presents new and compounding challenges to natural resource management. With shifting climate patterns, managers are confronted with difficult decisions on how to minimize climate impacts to habitats, infrastructure, and wildlife populations. Further, managers lack the information needed to make proactive management decisions. To address this problem, this project will develop a decision and adaptation framework to support site‐level decision‐making that facilitates thoughtful integration of climate change information into formal management and planning processes. In collaboration with the U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge System (NWRS), the proposed framework will integrate...

The Prairie Pothole Region is recognized as one of the most productive areas for waterfowl in North America and supports an estimated 50–80 % of the continent’s duck population. This important habitat is threatened by climate change and continued land-use change. The goal of this research is to establish a framework for assessing future impacts of climate and land-use change on Prairie Pothole wetland ecosystems in Minnesota and Iowa to better assist wetland managers in planning conservation actions. Historically, the southeast portion of the US Prairie Pothole Region in Minnesota and Iowa has faced some of the greatest challenges in wetland conservation. While advances have been made to restore these habitats,...

Forests across the U.S. are experiencing unprecedented tree mortality caused by a variety of stressors, including invasive insects, disease, extreme weather, wildfires, and droughts. For example, the emerald ash borer, a nonnative insect, has killed tens of millions of trees in the Lake States region of Minnesota, Wisconsin, and Michigan alone in the past decade. Tree die offs alter the structure of forests, making them less-suitable habitat for many species, and decrease their ability to perform important ecosystem functions, such as carbon sequestration. Climate change further threatens already damaged forests, as shifting temperature and precipitation conditions alter species’ range limits. To prevent additional...

Floodplain forests along the Upper Mississippi River are heavily managed but understudied systems that provide critical ecosystem services, including habitat for endangered species. Impacts of a changing climate, such as warmer winters and wetter summers with extreme precipitation events, are already influencing hydrologic patterns in these ecosystems, including altering the duration, frequency, and timing of floods. These changes bring numerous challenges to floodplain forest managers. This project will leverage an already established research-management partnership to develop knowledge and tools to inform sustainable decision making. In this project, researchers will utilize multiple sources of “big data” to...

In 2020, in partnership with the Northeast Climate Adaptation Science Center (NE CASC), the Midwest Climate Adaptation Science Center (MW CASC) completed a four-part process to identify climate science priorities for both the Northeast and Midwest regions. The process included: structured feedback from an advisory committee, the completion of six listening sessions, feedback from project partners, and a review of regional climate initiatives. These efforts identified five management challenges for the MW CASC: 1) heavy precipitation events and drought, 2) loss of winter, 3) altered water levels, flows and temperatures, 4) new terrestrial landscapes resulting from climate change, and 5) barriers and opportunities...

Cyanobacteria blooms are one of the most significant management challenges in the Great Lakes today. Recurring blooms of varying toxicity are commonly observed in four of the Great Lakes, and the fifth, Lake Superior, has experienced intermittent nearshore blooms since 2012. The recent advent of cyanobacterial blooms in Lake Superior is disconcerting, given the highly valued, pristine water quality of the large lake. It is possible that the ecological state of Lake Superior is shifting and that we are witnessing the beginnings of larger and longer lasting bloom events. As a public resource, the coastal water quality of Lake Superior has tremendous economic, public health, and environmental value, and therefore,...

Fisheries managers in Midwestern lakes and reservoirs are tasked with balancing multiple management objectives to help maintain healthy fish populations across a landscape of diverse lakes. As part of this, managers monitor fish growth and survival. Growth rates in particular are indicators of population health, and directly influence the effectiveness of regulations designed to protect spawning fish or to promote trophy fishing opportunities. Growth, combined with reproduction and survival, also determines the amount of fish biomass available for harvest, known as population production. Changing water temperatures can influence growth and production of managed fish species in multiple complex ways, increasing the...

The prairie grasslands of the Midwest and Great Plains provide important habitat for a wide variety of plants and animals, clean drinking water, and space for outdoor recreation and have experienced an over 99% loss of prairie grasslands due to a variety of factors including climate change. Land managers that are working to restore prairie grasslands would like to make them resilient to a shifting climate. However, they have limited information about how to plan these restorations with climate adaptation in mind In the Midwest and throughout much of North America, the effects of climate change are more pronounced and rapid in winter than in other seasons. Winters generally have less snow leaving plants more exposed...

Habitat loss, pollution, species introductions, and overfishing have been impacting inland fisheries for decades. Climate change threatens to compound the factors that lead to fisheries decline. Walleye, an ecologically, economically and culturally important cool-water sportfish, have been declining in the Upper Great Lakes Region since the early 2000s. Yet while many inland walleye populations have declined, others have thrived, and some even appear to respond positively to warming temperatures in certain contexts (e.g. Honsey et al 2020). Rather than focusing on understanding walleye population declines, this project’s approach is to probe the factors that underlie successful, thriving fisheries. Focusing on ‘bright...

Climate change has the potential to change the kinds and numbers of fish and wildlife that are available for recreationists such as hunters, anglers, and birdwatchers. While we have some knowledge about what changes might look like concerning different fish and wildlife species, very little information is known about how anglers, hunters, and wildlife watchers might view such changes in the areas where they recreate. We also know very little about such users’ attitudes toward potential management actions and strategies for adapting to potential climate change that affects fish and wildlife. Using web-based social surveys, the research team will gauge public values, attitudes, preferences as it relates to risk perception...

Aquatic invasive species threaten our lakes, streams, and wetlands. These species not only change the biology within the waterbody, but they can change the way we use those waterbodies and the resources they produce. Those changes may have large economic impacts, such as direct management costs and indirect costs to fisheries, tourism and commerce. These species can be small like zebra mussels or large like Asian carp, but one thing they have in common is being difficult to manage and to prevent further spread. To help inform control measures for aquatic invasive species, local, state, and federal natural resource management agencies have been working to develop risk assessments to understand the potential spread...

Habitat loss is splitting the world’s plant and animal populations into smaller, more isolated fragments. At the same time, many organisms must also withstand rapid and stressful changes to their environment. Combined, these factors can increase extinction risk. A possible escape from extinction is through adaptation. Yet, small populations with low genetic diversity may be unable to adapt in time to keep pace with environmental change. One strategy to mitigate these problems is to move individuals from larger, more resilient populations with higher genetic variation into small, declining populations to induce 'genetic rescue'. This project will use cutting-edge genomic tools to evaluate the potential for genetic...

Water levels in the Great Lakes are fluctuating in ways that we have not seen in the past, with both historically low- and high-water levels occurring in the last decade. Expectations are that larger and more frequent water-level fluctuations will occur in response to climate change. The increased variability in lake levels has implications for the management of invasive plants found in the coastal wetlands that surround the Great Lakes, with some species benefiting from periods of low water levels. Phragmites australis, a prominent invasive grass that disrupts fish and wildlife habitats, thrived during the most recent period of low lake levels. However, periods of high lake levels could provide managers with opportunities...

The project aims to understand the state of climate adaptation practice in sectors related to natural and cultural resource management and conservation in the Midwest region. An example of these efforts is developing plans that include natural resource management and conservation actions as part of a response to the impacts of climate change on nature and people. By learning from these plans, we aim to gain a comprehensive understanding of past and current adaptation efforts in the Midwest, as well as of the on-the-ground barriers and opportunities resource managers face in planning for climate adaptation in this region. Additionally, we seek to identify best practices in adaptation planning that can help resource...

Many Midwestern lakes are experiencing warming water temperatures as a result of climate change. In general, this change is causing coldwater fish species such as cisco and coolwater species such as walleye to decline. Meanwhile, warmer water species such as largemouth and smallmouth bass are increasing as temperatures warm. However, some fish populations are more vulnerable to these changes than others. This divergence could be the result of interactions between climate and habitat conditions, or as a result of interactions among fish species. For example, walleye responses to warming temperatures could vary depending on the abundance of largemouth bass. The goal of this project is to quantify the responses of...

Stocking, or raising fish in hatcheries and releasing them into a body of water, is routinely used to supplement or maintain fisheries when natural populations are low or nonexistent. Demand for stocking cool and coldwater fish species that support important fisheries will likely increase as a result of climate change, but fish available for stocking are a limited resource. Consequently, climate change will likely affect supply-and-demand tradeoffs associated with stocking fish in the future, where demand for fish is likely to exceed supply. Researchers will examine supply-and-demand tradeoffs using walleye, which represent an ideal species for this assessment because they are a native coolwater species supporting...
