Timing of snowshoe hare winter color swap may leave them exposed in changing climate, study finds      (via sciencedaily.com)     Original source 

A new study, which used 44 years of data, shows that as the globe has warmed, altering the timing and amount of snow cover, snowshoe hares' winter transformation may be out of sync with the color of the background environment; this may actually put them at a greater disadvantage.

Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists      (via sciencedaily.com)     Original source 

Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.

Humans need Earth-like ecosystem for deep-space living      (via sciencedaily.com)     Original source 

Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.

Shutting down nuclear power could increase air pollution      (via sciencedaily.com)     Original source 

A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.

In Florida study, nonnative leaf-litter ants are replacing native ants      (via sciencedaily.com)     Original source 

A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.

Coral skeletons influence reef recovery after bleaching      (via sciencedaily.com)     Original source 

Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

Innovative method predicts the effects of climate change on cold-blooded animals      (via sciencedaily.com) 

In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.

Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk      (via sciencedaily.com) 

Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.

Hope for salamanders? Study recalibrates climate change effects      (via sciencedaily.com) 

For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.

Scientists discover hidden crab diversity among coral reefs      (via sciencedaily.com) 

The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.

Most of world's salt marshes likely to be underwater by 2100, study concludes      (via sciencedaily.com) 

Salt marshes are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. According to new research, more than 90 percent of the world's salt marshes are likely to be underwater by the end of the century. These findings come from a 50-year study of ecosystem changes in Great Sippewissett Marsh in Falmouth, Mass.

Cooking up plasmas with microwaves      (via sciencedaily.com)     Original source 

Scientists have created plasmas with fusion-suitable densities, using microwave power with low frequency. The research team has identified three important steps in the plasma production: lightning-like gas breakdown, preliminary plasma production, and steady-state plasma. Blasting the microwaves without alignment of Heliotron J's magnetic field created a discharge that ripped electrons from their atoms and produced an especially dense plasma.

Even Sonoran Desert plants aren't immune to climate change      (via sciencedaily.com) 

In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.

New type of entanglement lets scientists 'see' inside nuclei      (via sciencedaily.com) 

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.

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.
