Vegetation history since the last glacial maximum in the Ozark highlands (USA): A new record from Cupola Pond, Missouri Vegetation history since the last glacial maximum in the Ozark highlands (USA): A new record from Cupola Pond, Missouri
The timing and drivers of vegetation dynamics and formation of no-analog plant communities during the last deglaciation in the unglaciated southeastern US are poorly understood. We present a multi-proxy record spanning the past 19,800 years from Cupola Pond in the Ozarks Mountains, consisting of replicate high-resolution pollen records, 25 AMS radiocarbon dates, and macrofossil, charcoal...

The first 100 years of pollen analysis The first 100 years of pollen analysis
In 1916, Swedish geologist Ernst Jakob Lennart von Post delivered a provocative lecture in Oslo, Norway, advocating the use of pollen grains in bog sediments as indicators of past vegetation and climate. The lecture spawned many applications and represents a landmark in multidisciplinary science.

Merging paleobiology with conservation biology to guide the future of terrestrial ecosystems Merging paleobiology with conservation biology to guide the future of terrestrial ecosystems
The current impacts of humanity on nature are rapid and destructive, but species turnover and change have occurred throughout the history of life. Although there is much debate about the best approaches to take in conservation, ultimately, we need to permit or enhance the resilience of natural systems so that they can continue to adapt and function into the future. In a Review, Barnosky...

Toward a national, sustained U.S. ecosystem assessment Toward a national, sustained U.S. ecosystem assessment
The massive investment of resources devoted to monitoring and assessment of economic and societal indicators in the United States is neither matched by nor linked to efforts to monitor and assess the ecosystem services and biodiversity that support economic and social well-being. Although national-scale assessments of biodiversity (1) and ecosystem indicators (2) have been undertaken...

Managing climate change refugia for climate adaptation Managing climate change refugia for climate adaptation
Refugia have long been studied from paleontological and biogeographical perspectives to understand how populations persisted during past periods of unfavorable climate. Recently, researchers have applied the idea to contemporary landscapes to identify climate change refugia, here defined as areas relatively buffered from contemporary climate change over time that enable persistence of...

The precision problem in conservation and restoration The precision problem in conservation and restoration
Within the varied contexts of environmental policy, conservation of imperilled species populations, and restoration of damaged habitats, an emphasis on idealized optimal conditions has led to increasingly specific targets for management. Overly-precise conservation targets can reduce habitat variability at multiple scales, with unintended consequences for future ecological resilience. We...
