In a paper published online this month in Frontiers in Ecology and the Environment, ESA member Bruce Robertson and his colleagues in biology and biophysics explore the concept of polarized light pollution. They synthesize work that shows how light reflected off of human-made surfaces can confuse animals and alter their behavior, leading to injury or even death. The American Museum…
Eastern Fence Lizards are rampant across the American southeast but, in recent years, they’ve begun to coexist with invasive red fire ants from South America. Because the lizards and the ants have similar requirements (terrestrial areas with abundant sunlight), they often find themselves occupying the same space. And the ants don’t like it. Tracy Langkilde of Penn State University studies…
Tree deaths have more than doubled in the western U.S. in the past 20-30 years, and the culprit is climate change, according to a paper published Friday in Science. Warming has all kinds of consequences for species ranges. Changes in temperature can narrow a species’ range or move it latitudinally through changes in average yearly temperatures and alterations of the…
There’s been a lot of buzz in Washington these past few weeks, and a good deal of it is about science. Here are highlights from today’s issue of the ESA Policy News Update, written by ESA’s Policy Analyst, Piper Corp. Science in the Economic Stimulus Bill. An $825 billion economic stimulus package, the American Recovery and Reinvestment Bill of 2009,…
President Barack Obama has been an inspiration to many scientists during his campaign and his transition to office because of his repeated commitments to the sciences and his early appointments of scientists in high-profile cabinet positions and advisory roles. Yesterday he renewed those sentiments in his inauguration speech, vowing to “restore science to its rightful place” in our government. The…
The promise of biofuels – fuel made from plant material – has taken a nosedive as scientists predict its generation could cause far more greenhouse gas emissions than it would make up for in preventing the use of fossil fuels. But a Michigan State chemist has asserted in a paper in Environmental Science & Technology online that if sustainable management…
ESA sent a letter today to president-elect Barack Obama recommending top priorities where ecological science should inform policy decisions in the new administration. Obama has already pledged his commitment to curbing climate change during his term. ESA applauded that commitment and outlined four other priorities for the next administration: ▪ Protecting water quality and quantity, especially in conjunction with worldwide…
Here’s a story of species introduction, invasion and trophic cascades to boggle the mind of even the most seasoned community ecologist. Macquarie Island is a 60-mile square piece of paradise in the southwest Pacific Ocean, south of Australia and New Zealand where one can find four species of seals and five of penguins. In the early 19th century, feral cats…
Eminent biologists E.O. Wilson and Thomas Lovejoy have written a letter to Carol Browner, incoming Special Assistant to the President for Energy & Climate Change, that calls on the new administration to not only act immediately to set standards for reducing greenhouse gas emissions but also to address the amelioration of climate change’s impacts on the natural world. Based on…
From the first college introductory biology class, budding biologists are taught the fundamentals of evolution by natural selection. The field of study is soundly rooted in the concept…so soundly, in fact, that scientists often take for granted its validity, snubbing their noses at and refusing to engage in any debate on the topic. But the issue has come to the…
One of last week’s Nature editorials extols the 109th annual Christmas bird count, a tradition started by the National Audubon Society as an alternative to the former competitive sport of shooting birds to mark the holidays. The survey, which takes place during a three-week interval that overlaps Christmas and New Year’s Day each year, involves birders of all ages and…
The concept of biological control is no new idea in ecology – people have been transporting living things to control other living things since the late 18th century. The most famous examples seem to be the big failures, where biocontrols become invasive themselves – such as mongooses introduced to Hawaii to control rats but that instead decimated populations of native…
