Biography
Jennifer Cartwright is an ecologist and geographer at the Tennessee office of the Lower Mississippi-Gulf Water Science Center. She investigates the abiotic drivers of biodiversity across a range of aquatic and terrestrial ecosystems. Recent work has included remote-sensing analysis of drought patterns, studies of inundation patterns in seasonal wetlands, assessments of springs as potential ecohydrologic refugia from climate change, and studies of climate-sensitive ecosystems supporting endemic plant species. Techniques include landscape-level geospatial investigations, climate-change analysis of specialized ecosystems, and ecological applications of remote-sensing technologies.

Climate- and Land-Cover-Induced Shifts in the Distribution and Abundance of Invasive Fish and Their Impacts on Native Fish Communities in the Tennessee and Cumberland River Basins
The climate of the Southeast is changing rapidly. As streams warm and streamflow dynamics change due to climate and land-cover changes, previously unsuitable habitats may become hospitable for invasive species. Warmwater and large-river adapted invasive species such as Asian carps may move upstream as habitats that were previously too cold or had too little flow become welcoming environments...
Clarifying Science Needs for Southeastern Grasslands
Grasslands are plant communities that have few or no trees, or have open canopies that allow for the development of a grassy groundcover. Grasslands in the southeastern U.S. support rare plant and animal species and in some cases qualify as global or regional hotspots of biodiversity. Yet the Southeast’s grasslands have been reduced by approximately 90% since European settlement, as the result...
Climate Refugia and Resilience Atlas: Identifying Priority Areas for Conserving Species of Concern in a Changing Climate
Climate change threatens many wildlife species across the Pacific Northwest. As the climate continues to change, wildlife managers are faced with the ever-increasing challenge of allocating scarce resources to conserve at-risk species, and require more information to prioritize sites for conservation. However, climate change will affect species differently in different places. In fact, some...

Mapping Climate Change Resistant Vernal Pools in the Northeastern U.S.
Vernal pools are small, seasonal wetlands that provide critically important seasonal habitat for many amphibian species of conservation concern. Natural resource managers and scientists in the Northeast, as well as the Northeast Refugia Research Coalition, coordinated by the Northeast CSC, recently identified vernal pools as a priority ecosystem to study, and recent revisions to State Wildlife...
Identifying and Evaluating Refugia from Drought and Climate Change in the Pacific Northwest
Warmer temperatures and less precipitation in the western U.S. related to climate change are harming many important natural resources, including forests, rivers, and many fish and wildlife species. Climate refugia provide a potential opportunity for conserving resources and biodiversity in the face of climate change. These refugia are places where the climate will likely change less than the...

Assessing Climate-Sensitive Ecosystems in the Southeastern U.S.
The southeastern U.S. contains a unique diversity of ecosystems that provide important benefits, including habitat for rare wildlife and plants, improved water quality, and recreation opportunities. Understanding how climate change will affect these ecosystems is vital for knowing how best to protect them and the services they supply. The goal of this project was to assess the climate change...
Topographic, soil, and climate drivers of drought sensitivity in forests and shrublands of the Pacific Northwest, USA
Climate change is anticipated to increase the frequency and intensity of droughts, with major impacts to ecosystems globally. Broad-scale assessments of vegetation responses to drought are needed to anticipate, manage, and potentially mitigate climate-change effects on ecosystems. We quantified the drought sensitivity of vegetation in the Pacific...
Cartwright, Jennifer M.; Littlefield, Caitlin E; Michalak, Julia; Lawler, Joshua J.; Dobrowski, SolomonStressor identification framework of biological impairment in Mississippi streams to support watershed restoration and TMDL development
The Clean Water Act (CWA) requires States to identify waters that are impaired for designated uses. These waters are published through a State’s §303(d) list. The CWA also requires that a total maximum daily load (TMDL) be completed for each water body to calculate the maximum amount of contaminants that can be present in that water body and still...
Hicks, Matthew B.; Cartwright, Jennifer M.Legacy effects of hydrologic alteration in playa wetland responses to droughts
Wetland conservation increasingly must account for climate change and legacies of previous land-use practices. Playa wetlands provide critical wildlife habitat, but may be impacted by intensifying droughts and previous hydrologic modifications. To inform playa restoration planning, we asked: (1) what are the trends in playa inundation? (2) what...

This guidebook provides user-friendly overviews of a variety of spatial datasets relevant to conservation and management of natural resources in the face of climate change in the Pacific Northwest, United States. Each guidebook chapter was created using a standardized template to summarize a spatial dataset or a group of closely related datasets....

Climate‐change adaptation focuses on conducting and translating research to minimize the dire impacts of anthropogenic climate change, including threats to biodiversity and human welfare. One adaptation strategy is to focus conservation on climate‐change refugia (that is, areas relatively buffered from contemporary climate change over time that...

Evaluating springs as potential hydrologic refugia in drying climates
Springs in water-limited landscapes are biodiversity hotspots and keystone ecosystems, disproportionately influencing surrounding landscapes despite their often small areas. Some springs served as evolutionary refugia during previous climate drying, supporting relict species in isolated habitats. Understanding whether springs will provide...

Climate‐change refugia – locations likely to facilitate species persistence under climate change – are increasingly important components of conservation planning. Recent approaches for identifying refugia at broad scales include identifying regions that are projected to experience less severe changes (climatic exposure), that contain a diversity...

Disturbance refugia – locations that experience less severe or frequent disturbances than the surrounding landscape – provide a framework to highlight not only where and why these biological legacies persist as adjacent areas change but also the value of those legacies in sustaining biodiversity. Recent studies of disturbance refugia in forest...

Water resource managers are challenged to balance growing water demand with protecting aquatic ecosystems and biodiversity. Management decisions can benefit from improved understanding of water withdrawal impacts on hydrologic regimes and ecological assemblages. This study used Ecological Limit Functions for fish groups within the Tennessee and...
Driver, Lucas; Cartwright, Jennifer M.; Knight, Rodney; Wolfe, William J.Ecological islands: Conserving biodiversity hotspots in a changing climate
For decades, botanists have recognized that rare plants are clustered into ecological “islands”: small and isolated habitat patches produced by landscape features such as sinkholes and bedrock outcrops. Insular ecosystems often provide unusually stressful microhabitats for plant growth (eg because of thin soils, high temperatures, extreme pH, or...
Cartwright, Jennifer M.Landscape topoedaphic features create refugia from drought and insect disturbance in a lodgepole and whitebark pine forest
Droughts and insect outbreaks are primary disturbance processes linking climate change to tree mortality in western North America. Refugia from these disturbances—locations where impacts are less severe relative to the surrounding landscape—may be priorities for conservation, restoration, and monitoring. In this study, hypotheses concerning...
Cartwright, Jennifer M.Springs as hydrologic refugia in a changing climate? A remote sensing approach
Spring‐fed wetlands are ecologically important habitats in arid and semi‐arid regions. Springs have been suggested as possible hydrologic refugia from droughts and climate change; however, springs that depend on recent precipitation or snowmelt for recharge may be vulnerable to warming and drought intensification. Springs that are expected to...
