Arizona State University geographer calls for complexity in sustainability science models
WASHINGTON – Tropical deforestation is intimately linked with urban dynamics and needs to be considered along with the role and effect of national and regional policies on land use decisions, and the dynamics of economic globalization in the next gen…
Arizona State University archaeologist models past and future landscapes
WASHINGTON — Archaeology is a vital tool in understanding the long-term consequences of human impact on the environment. Computational modeling can refine that understanding. But according to Arizona State University archaeologist C. Michael Barto…

A panel of scientists speaking today at the annual meeting of the American Association for the Advancement of Science (AAAS) unveiled new research and models demonstrating how climate change could increase exposure and risk of human illness originat…
Scientists discover agave’s tremendous potential as new bioenergy feedstock
Champaign, IL — February 4, 2011 – An article in the current issue of Global Change Biology Bioenergy reviews the suitability of Agave as a bioenergy feedstock that can sustain high productivity in spite of poor soil and stressful climatic conditi…
P Summit calls for a ‘new alchemy’ around phosphorus and food
The problem with phosphorus, a critical element in fertilizers and food, is, as comedian Rodney Dangerfield would say, that it “can’t get no respect.”
Increasingly scarce, yet commonly overused in agricultural fields, polluting streams and lakes,…
Biogeochemistry at the core of global environmental solutions
Millbrook, NY — If society wants to address big picture environmental problems, like global climate change, acid rain, and coastal dead zones, we need to pay closer attention to the Earth’s coupled biogeochemical cycles. So reports a special i…
Learning causes structural changes in affected neurons
When a laboratory rat learns how to reach for and grab a food pellet — a pretty complex and unnatural act for a rodent — the acquired knowledge significantly alters the structure of the specific brain cells involved, which sprout a whopping …
Fishy consequences of transplanting trout, salmon, whitefishes
Montreal, January 26, 2011 — Not all trout are created equal. Those swimming up the streams of British Columbia might resemble their cousins from Quebec, yet their genetic makeup is regionally affected and has an impact on how they reproduce, …
Man, volcanoes and the sun have influenced Europe’s climate over recent centuries
An International research team has discovered that seasonal temperatures in Europe, above all in winter, have been affected over the past 500 years by natural factors such as volcanic eruptions and solar activity, and by human activities such …
Climate disasters: New Baylor study explores how people respond
New results from a Baylor University study show that different behaviors and strategies lead some families to cope better and emerge stronger after a weather-related event.
Dr. Sara Alexander, an applied social anthropologist at Baylor who conduc…
Climate change to continue to year 3000 in best case scenarios
New research indicates the impact of rising CO2 levels in the Earth’s atmosphere will cause unstoppable effects to the climate for at least the next 1000 years, causing researchers to estimate a collapse of the West Antarctic ice sheet by the year 3…
Gesturing while talking helps change your thoughts
Sometimes it’s almost impossible to talk without using your hands. These gestures seem to be important to how we think. They provide a visual clue to our thoughts and, a new theory suggests, may even change our thoughts by grounding them in action. …
UNH scientists help show potent GHG emissions are 3 times estimated levels
DURHAM, N.H. — In a study published December 20 in the Proceedings of the National Academy Sciences (PNAS), a team of researchers including University of New Hampshire scientists Wilfred Wollheim, William McDowell, and Jody Potter details findings…
Thoreau’s study of birds at Waldon Pond aids BU biologists in climate change research
BOSTON — Boston University biology professor Richard Primack, graduate student Elizabeth Ellwood, and recent graduate Michelle Talmadge completed an analysis of the changing arrival dates of migratory birds to Concord, Massachusetts that includes …
Pacific Northwest National Laboratory’s 2010 AGU tip sheet
SAN FRANCISCO — Scientists from the Department of Energy’s Pacific Northwest National Laboratory will present their research at the 2010 American Geophysical Union Fall Meeting, which runs Monday, Dec. 13 through Friday, Dec. 17 at the Moscone Con…
Many coastal wetlands likely to disappear this century
Many coastal wetlands worldwide — including several on the U.S. Atlantic coast — may be more sensitive than previously thought to climate change and sea-level rise projections for the 21st century.
U.S. Geological Survey scientists made thi…
Water resources played important role in patterns of human settlement, new UNH research shows
DURHAM, N.H. — Once lost in the mists of time, the colonial hydrology of the northeastern United States has been reconstructed by a team of geoscientists, biological scientists and social scientists, including University of New Hampshire Ph.D. can…
Should our biggest climate change fear be fear itself?
From apocalyptic forecasting to estimates of mass extinctions, climate change is a topic which is filled with fearful predictions for the future. In his latest research, published in WIREs Climate Change, historian Matthias Dörries examines the cul…
New research identifies the plight of farmland birds
Farmland birds that are poorer parents and less “brainy” are faring worse than other farmland bird species, a study at the University of Bristol has found.
The new research, published today in Proceedings of the Royal Society B, found that farmla…
Broad range of research presented to Geological Society of America
