Pollen records, postglacial: Southeastern North America
Pollen records from the unglaciated southeastern region of North America provide an overview of biogeographic changes associated with vegetational migration northward following the retreat of the Laurentide Ice Sheet. Changing insolation during the Holocene affected forest composition on the Coastal Plain, and rising sea level controlled the distribution of marsh and forested wetlands...
Effects of recent wildfires on giant sequoia groves were anomalous at millennial timescales: a response to Hanson et al.
BackgroundThe giant sequoia (Sequoiadendron giganteum [Lindley] Buchholz) of California’s Sierra Nevada recently suffered historically unprecedented wildfires that killed an estimated 13–19% of seed-bearing sequoias across their native range. Hanson et al. recently sought to characterize post-fire reproduction in two severely burned sequoia groves, but their two papers (1) inaccurately...
Microplastic and associated black particles from road-tire wear: Implications for radiative effects across the cryosphere and in the atmosphere
The environmental effects of airborne micro- and nano-size plastic particles are poorly understood. Microscopy and chemical analyses of atmospherically deposited particles on snow surfaces at high elevation (2,865–3,690 m) in the Upper Colorado River basin (UCRB; Colorado Rocky Mountains) revealed the presence of black substances intimately associated with microplastic fibers, particles...

USGS Ecosystems Science for Food and Water Security
USGS science developed by the Ecosystems Mission Area helps ensure safe and abundant domestic food and water supplies, ensuring all Americans access to livelihoods and traditions that connect generations with each other and the outdoors and strengthen America’s self-reliance. USGS science is used by decision makers at all levels to understand how the quality of America’s food supply is directly...
USGS Ecosystems Science in Support of Economic Growth
Science provided by the USGS Ecosystems Mission Area helps boost America’s economy by providing practical tools to implement cost-effective management and development strategies that supports the Nation’s economic growth and protects our natural heritage.
Glaciers and Landscape Change
Mountain glaciers are dynamic reservoirs of frozen water, deeply interconnected with their surrounding ecosystems. Glacier change in North America has major societal impacts, including to water resources, natural hazard risk, tourism disruption, fisheries, and global sea level change. Understanding and quantifying precise connections between changing glaciers, the surrounding landscape and climate...
