Achoo! Native Echinacea angustifolia plant is blown away
February 5, 2014 08:17 AM - Robin Blackstone, ENN
Echinacea, a genus of flower in the daisy family is sold in many over-the-counter cold and flu remedies and sold in pharmacies and health and nutrition stores. Echinacea has nine wild species in eastern and central North America that grow in moist to dry prairies and in open wooded areas. The genus includes the purple coneflower, pale purple coneflower and narrow-leaved purple coneflower. All have large magenta petals that unfurl from early to late summer.
24 fewer days of winter ice
February 4, 2014 09:09 AM - ClickGreen Staff, ClickGreen
The winter ice season is now 24 days shorter than it was in 1950 as Arctic lakes are freezing up later in the year and thawing earlier, according to a new study. The University of Waterloo research, sponsored by the European Space Agency (ESA), also reveals that climate change has dramatically affected the thickness of lake ice at the coldest point in the season. In 2011, Arctic lake ice was up to 38 centimeters thinner than it was in 1950.
Comets and Woolly Mammoths

New evidence suggests that a comet collision might have been the trigger for the Younger Dryas, contributing to North America's megafauna extinction. UC Santa Barbara's James Kennett, professor emeritus in the Department of Earth Science, posits that such an extraterrestrial event did occur killing off woolly mammoths, giant ground sloths and saber-tooth tigers 12,900 years ago.
L'Oreal moves against forest destruction

L'Oreal, the world's largest beauty and cosmetics company, has committed to remove forest destruction from its products by 2020. Top brands like Garnier, Diesel, Lancome, Giorgio Armani and Yves St Laurent will no longer be contribute to forest destruction following this promise by the world's biggest beauty products company.
Extreme Weather Events Create Uncertain Future for Penguins
January 30, 2014 05:34 AM - EurekAlert
Changes in average climatic conditions combined with the increasing frequency of unpredictable, extreme weather events may disrupt scientific predictions of the future penguin populations, according to a study published in PLOS ONE on January 29, 2014 by Amélie Lescroël from the Centre d'Ecologie Fonctionnelle et Evolutive (CNRS), France and colleagues.
Slowing down the floodwaters
January 29, 2014 10:41 AM - Robin Blackstone, ENN
Putting something called "Natural Engineering" to work in a five-year research project, Newcastle University in cooperation with the Environment Agency are discovering the benefits utilizing the land's natural defenses to slow river flow downstream and prevent flooding. Slowing down water in anticipation of flooding events is being tested all over the world. Strategies include the use of retention basins; wetlands development; levee systems and floodwalls but Newcastle University researchers directed by Dr. Mark Wilkinson are employing additional water retention strategies further up in the catchment system. The Belford Burn is a small catchment system located in Northumberland, a community just south of the Scottish border.
Amazing discovery in Antarctica: sea anemones found living upside down under ice
January 28, 2014 09:12 AM - Jeremey Hance, MONGABAY.COM
Sea anemones are supposed to sit on the bottom of the ocean, using their basal disc (or adhesive foot) to rest on a coral reef or sand. So, imagine the surprise of geologists in Antarctica when they discovered a mass of sea anemones hanging upside from the underside of the Ross Ice Shelf like a village of wispy ghosts.
Island Living Shapes Physiology and Lifestyle of Eastern Bluebirds
January 27, 2014 03:56 PM - ENN Staff
Island plants and animals often differ from their mainland relatives. Why? In general, isolated islands lack top predators and large herbivores, which can influence food chains and traits of island organisms. In addition, differences in human interactions and threats posed by pathogens and parasites can also contribute to variances in traits. In a case study involving eastern bluebirds, (Sialia sialis) researchers show just how island life shapes the physiology and life history of a species.
"Phosphate free for all" from P & G
January 27, 2014 09:26 AM - Click Green Staff, ClickGreen
Consumer product giant Procter & Gamble has announced that it will eliminate phosphates from all of its laundry detergents worldwide within the next two years. The change applies to brands including Tide, Ariel, Ace and Bonux, and will maximize the conservation of precious resources and reduce the threat of water pollution.
Mice and Moose and climate change
January 26, 2014 09:26 AM - Roger Greenway, ENN
How do animals adjust to a warming climate? Do all animals respond in the same way? According to a new study by the University of Colorado at Boulder, if you were a shrew snuffling around a North American forest, you would be 27 times less likely to respond to climate change than if you were a moose grazing nearby. That is just one of the findings of a new University of Colorado Boulder assessment led by Assistant Professor Christy McCain that looked at more than 1,000 different scientific studies on North American mammal responses to human-caused climate change. The CU-Boulder team eventually selected 140 scientific papers containing population responses from 73 North American mammal species for their analysis. "If we can determine which mammals are responding to climate change and the ones that are at risk of disappearing, then we can tailor conservation efforts more toward those individual species," said McCain. "Hopefully, this potential loss or decline of our national iconic mammals will spur more people to curb climate impacts by reducing overuse of fossil fuels."
