An ericoid mycorrhizal fungus similar to the ones found in rhododendrons. Mycorrhizae are fungi that form mutually beneficial associations with plant roots. The mutualism works like this: The mycorrhiza grows in and around the plant’s root tissue, and its hyphae, or thread-like vegetative parts, serve plants by branching out in the soil and absorbing nutrients that are of importance to…
New movement patterns may be a sign of good news for blue whales. Blue whales have begun moving around the ocean in ways that strongly resemble their historical patterns before the advent of the whaling trade. A century ago, about 300,000 blue whales existed. But in the early 1900s, humans hunted and killed 99.9 percent of them. The population decimation…
Jane Lubchenco, the administrator of NOAA (who, by the by, is a former president of ESA), gave a great interview on this week’s Living on Earth series. If you don’t listen to Living on Earth, it’s an excellent weekly radio show by Public Radio International that focuses on environmental issues. Lubchenco told the Living on Earth folks that she wants…
Yesterday, the White House released its $3.4 trillion budget proposal for fiscal year 2010. Overall, the sciences fared well, with many significant increases for renewable energy and environmental programs. Below is a breakdown of science funding to various government agencies from ESA’s Policy News, written by ESA Policy Analyst Piper Corp.
A. colberti, the new beetle species Stephen Colbert, that humble, modest satirist who shuns the spotlight and demurely rejects recognition, finally has an animal named after him: a species of Neotropical diving beetle, Agaporomorphus colberti. The two taxonomists who named the species, Kelly Miller at UNM and Quentin Wheeler at ASU, are no stranger to naming new species after famous…
The EPA released a report yesterday that proposes to change the rules of the biofuels game. The report, titled “Regulation of Fuels and Fuel Additives: Changes to Renewable Fuel Standard Program,” examines the lifecycle of corn-for-ethanol practices and sets the “payback” period of carbon emissions for corn-for-ethanol fuel as 33 years. The payback period means that at first, corn-for-ethanol practices…
The world of academia used to be a place where professors and students stayed shuttered away in their research labs and offices, doing their research for the benefit of one another, with no desire to engage in the public eye. Cynics may chuckle and comment that this stereotype is still largely true today. But more and more, institutions and granting…
White-nose syndrome, a mysterious disease that has been killing hundreds of thousands of North American bats since its discovery in 2007, has now forced the U.S. Forest Service to close caves in national forests across the country in an attempt to rein in transmission of the disease. The disease is caused by a cold-loving fungus that infects bats’ faces and…
Although not all birds mate for life, many do, and often mated pairs will stay together at least for the duration of a reproductive season. Birds are sneaky, however, and some “sneaker” males will often try to stealthily mate with females within pairs. Behavioral ecologists have many theories about why females engage in these extra-pair copulations. Since the birds can…
Nature announced today that it is modifying its authorship policies for submission to its journals. The two major changes are that one senior author will be required to take “responsibility” for the paper, and that an explicit list of each coauthor’s role in the paper must be submitted. In a November 2007 editorial, the leadership at Nature suggested that a…
Climate change has the potential to not only increase average temperatures around the world, but also to increase the likelihood and severity of now-rare temperature events, like heat waves. The fate of many animal populations, therefore, can hinge on their ability to tolerate (relative) extreme heat. In the April issue of Functional Ecology, scientists explore the possible responses of animal…
President Obama addressed the attendees at the 146th annual meeting of the National Academy of Sciences this morning, where he highlighted new directives that support his science initiatives, including a new agency for high-risk energy research and increased funding for education at the secondary and graduate levels. According to NAS President Ralph Cicerone, who gave introductory remarks, every room of…
