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.

Status: Active 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...

Status: Active 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...

Status: Active 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...

Status: Completed 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...

Status: Completed 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...

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...

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...

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...

Putting flow-ecology relationships into practice: A decision-support system to assess fish community response to water-management scenarios
This paper presents a conceptual framework to operationalize flow–ecology relationships into decision-support systems of practical use to water-resource managers, who are commonly tasked with balancing multiple competing socioeconomic and environmental priorities. We illustrate this framework with a case study, whereby fish community responses to...

Soil microbial community profiles and functional diversity in limestone cedar glades
Rock outcrop ecosystems, such as limestone cedar glades (LCGs), are known for their rare and endemic plant species adapted to high levels of abiotic stress. Soils in LCGs are thin (< 25 cm), soil-moisture conditions fluctuate seasonally between xeric and saturated, and summer soil temperatures commonly exceed 48 °C. The effects of these...
