New research led by Colorado State University has revealed that an estimated 100,000 elephants in Africa were killed for their ivory between 2010 and 2012. The study shows these losses are driving population declines of the world's wild African elephants on the order of 2 percent to 3 percent a year.
An interdisciplinary lab at Michigan Tech's Great Lakes Research Center brings air, earth and water scientists together to study climate and environmental issues.
Fish species native to a major Arizona watershed may lose access to important segments of their habitat by 2050 as surface water flow is reduced by the effects of climate warming, new research suggests.
As climate change alters habitats for birds and bees and everything in between, so too does the way humans decide to use land. Researchers at the University of Wisconsin-Madison and Aarhus University in Denmark have, for the first time, found a way to determine the potential combined impacts of both climate and land-use change on plants, animals and ecosystems across the country.
An international team of conservationist scientists and practitioners has published new research showing the precarious state of the world’s primary forests.
Novel ecosystems arise when human activities transform biological communities through species invasions and environmental change. They are seemingly ubiquitous, and thus many policymakers and ecologists argue for them to be accepted as the "new normal"—an idea the researchers say is a bad one.

When the Intergovernmental Panel on Climate Change recently requested a figure on global temperature trends for its annual report, the University of Wisconsin-Madison’s Zhengyu Liu knew that was going to be a problem. Liu and his colleagues describe a consistent global warming trend over the course of the Holocene counter to a study published last year.
A new study by the Wildlife Conservation Society (WCS), U.S. Geological Survey (USGS) and Idaho State University (ISU) explored how habitat alterations, including the addition of energy transmission towers, affect avian predators nesting in sagebrush landscapes.
Seismic events aren’t rare occurrences on Antarctica, where sections of the frozen desert can experience hundreds of micro-earthquakes an hour due to ice deformation. Some scientists call them icequakes. But in March of 2010, the ice sheets in Antarctica vibrated a bit more than usual because of something more than 3,000 miles away: the 8.8-magnitude Chilean earthquake. A new Georgia Institute of Technology study published in Nature Geoscience is the first to indicate that Antarctica’s frozen ground is sensitive to seismic waves from distant earthquakes.
Many of today’s technological innovations from the iPhone to electric motors for hybrid cars require the use of materials — elements — that are scarce or difficult to obtain. As demand for these devices grows, the problem of dwindling critical element supplies must be addressed. That’s the conclusion of a white paper written by eminent scientists. The product of the 5th Chemical Sciences and Society Summit (CS3), the white paper recommends focusing research on finding alternative materials and new approaches to technology development in order to prevent these elements from disappearing.
As the Food and Drug Administration mulls over whether to rein in the use of common antibacterial compounds that are causing growing concern among environmental health experts, scientists are reporting today that many pregnant women and their fetuses are being exposed to these substances. They will present their work at the 248th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
A plastic sponge that sops up the greenhouse gas carbon dioxide (CO2) might ease our tranisition away from polluting fossil fuels to new energy sources like hydrogen. At the 248th National Meeting & Exposition of the American Chemical Society, a researcher will describe a relative of food container plastics that could play a role in President Obama’s plan to cut CO2 emissions. The material might also someday be integrated into power plant smokestacks.
