Climate change represents one of the foremost drivers of ecological change, yet its impacts on biodiversity remain largely uncertain. Although the volume of scientific studies on climate-driven range shifts has grown in recent years, projections still vastly outnumber documented cases. Specific mechanisms remain difficult to isolate, given numerous potential drivers and high variability in observed shifts across species and regions. A framework for evaluating empirical evidence of range shifts is needed to assess commonly held hypotheses (e.g., poleward latitudinal shifts, upslope elevational shifts), clarify why species do and do not conform to expectations, and inform management responses. Using a hypothesis-driven approach, we assess climate-driven range shifts for species in the United States for which data are available. Through a systematic literature review of documented range shifts, and a combination of quantitative meta-analyses and qualitative confidence assessments, we evaluate the body of evidence on climate-driven range shifts and estimate the prevalence and magnitude of these changes. Furthermore, we use a climate change vulnerability framework to determine why observations support or fail to support commonly held hypotheses. Our analysis examines how varying levels of exposure, sensitivity, and capacity to adapt explain many of the idiosyncrasies associated with climate-driven range shifts. This work provides an iterative framework within which future observations can be added to further refine hypotheses. Our analysis provides updated evidence on where, how, and why species are shifting their ranges under climate change, and presents valuable information to inform a range of climate adaptation and wildlife management strategies.
Madeleine Rubenstein is a Biologist with the US Geological Survey National Climate Adaptation Science Center, where she studies the impacts of climate change on terrestrial ecosystems. Her research focuses on wildlife and ecosystem response to climate change, with an emphasis on producing national-scale synthesis assessments. She also works with natural resource managers across the Department of the Interior to develop a national research program that respond to needs of wildlife and habitat managers.
Before joining USGS, Madeleine earned a Master of Environmental Science at the School of Forestry and Environmental Studies at Yale University. While at Yale, she worked with the Wildlife Conservation Society to research effects of climate change on the phenology of boreal birds. Prior to graduate school, she was the Research Coordinator with the Columbia Climate Center at the Earth Institute of Columbia University, and interned with the Plant Ecology Lab at the Smithsonian Environmental Research Center. Madeleine has also worked on issues of international sustainable development with the Frankfurt Zoological Society and the Women’s Environment and Development Organization.
