Surprise effect: Methane cools even as it heats      (via sciencedaily.com) 

Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.

Giant volcanic 'chain' spills secrets on inner workings of volcanoes      (via sciencedaily.com) 

Volcanic relics scattered throughout the Australian landscape are a map of the northward movement of the continent over a 'hotspot' inside the Earth, during the last 35 million years.

Habitat will dictate whether ground beetles win or lose against climate change      (via sciencedaily.com) 

The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.

Towards reducing biodiversity loss in fragmented habitats      (via sciencedaily.com) 

By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.

'Rock stars' solve long-standing diamond conundrum      (via sciencedaily.com) 

Two researchers have used a standard laptop computer and a humble piece of rock -- from the 'waste pile' of a diamond mine -- to solve a long-held geological conundrum about how diamonds formed in the deep roots of the earth's ancient continents.

Forest growing season in eastern U.S. has increased by a month      (via sciencedaily.com) 

The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.

Douglas-fir in Klamath Mountains are in 'decline spiral'      (via sciencedaily.com) 

Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a 'decline spiral' in parts of the region.

Coffee plantations limit birds' diets      (via sciencedaily.com) 

A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.

Mountain forests are being lost at an accelerating rate, putting biodiversity at risk      (via sciencedaily.com) 

More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.

New study counts the environmental cost of managing Japanese knotweed      (via sciencedaily.com) 

New research has looked at the long-term environmental impact of different methods to control Japanese knotweed. Different ways of trying to control the invasive species have developed over the years but now, as sustainability becomes increasingly important, understanding the effect of these management methods is vital.This new study examines at the entire life cycle and long-term impacts of different management approaches.

Activity deep in Earth affects the global magnetic field      (via sciencedaily.com) 

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degrees C. New research from geophysicists suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

Brown widow spiders' aggression likely driver of black widow decline      (via sciencedaily.com) 

Black widow spiders have earned a fearsome reputation for their venomous bite. But in parts of the southern United States these spiders have much to fear themselves -- from spider relatives who really don't like their company. In the past couple decades, researchers have noticed black widow spiders being displaced by the brown widow, a fellow species in the same genus. But new research suggests this isn't a simple case of one species winning the competition for food or habitat. Instead, a study shows brown widow spiders have a striking propensity to seek out and kill nearby black widows.

Remarkable squirting mussels captured on film      (via sciencedaily.com) 

Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.
