A group of the world’s leading environmental scholars are sounding the alarm that human societies need to transform their national and international environmental institutions into a more coherent and robust planetary stewardship model to steer away from rapid and irreversible changes to the Earth’s subsystems.
University of Toronto political scientist Steven Bernstein is one of the authors of a paper which appears in Science on March 16, 2012. (more…)
What’s the best way to study the Antarctic’s ecosystem? Follow the penguins.
Scientists are tracking penguins on land, under the sea, and even from space to unravel the environmental dynamics in the West Antarctic Peninsula as the region experiences climate change.
“We’re not just down there bird watching,” said Matthew Oliver, assistant professor of oceanography in UD’s College of Earth, Ocean, and Environment. “This is a concerted effort to put the whole ecosystem together.” (more…)
UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.
The research, federally funded by the National Science Foundation, is published Dec. 2 in the journal Science.
The team’s groundbreaking integral projection model, or IPM, unites various sub-disciplines of population biology, including population ecology, quantitative genetics, population genetics, and life-span and offspring information, allowing researchers to link many different data sources simultaneously. Scientists can now change just a single variable, like temperature, and see how that affects many factors for a population.(more…)
SANTA CRUZ, Calif. — For the first time, scientists have been able to validate the age of deep-sea black corals in the Gulf of Mexico. They found the Gulf is home to 2,000 year-old deep-sea black corals, many of which are only a few feet tall.
These slow-growing, long-living animals thrive in very deep waters—300 meters (984 feet) and deeper—yet scientists say they are sensitive to what is happening in the surface ocean as well as on the sea floor. (more…)
An archeologist at Washington University in St. Louis is helping to reveal for the first time a snapshot of rural life in China during the Han Dynasty.
