Deforestation of sandy soils a greater climate threat
A new study finds that tree removal has far greater consequences for climate change in some soils than in others, a finding that could provide key insights into which ecosystems should be managed with extra care. In a comprehensive analysis of soil collected from 11 distinct U.S. regions, from Hawaii to northern Alaska, researchers found that the extent to which deforestation disturbs underground microbial communities that regulate the loss of carbon into the atmosphere depends almost ...

Foraging bats can warn each other away from their dinners
A new call that some bats use to tell other foraging bats to 'back off' from bugs they've claimed for themselves has been identified by scientists. This sound, called a 'frequency-modulated bout,' warns other bats away from prey. The researchers are first to report this ultrasonic social call produced exclusively by flying, foraging male big brown bats, in a new article.

Crows understand water displacement at the level of a small child: Show causal understanding of a 5- to 7-year-old child
New Caledonian crows may understand how to displace water to receive a reward, with the causal understanding level of a 5- to 7-year-old child. Understanding causal relationships between actions is a key feature of human cognition. However, the extent to which non-human animals are capable of understanding causal relationships is not well understood. Scientists used the Aesop's fable riddle -- in which subjects drop stones into water to raise the water level and obtain an out-of reach-reward ...

Natural history must reclaim its place, experts say
Scientists argue that the study of natural history has waned in recent decades in developed countries. Declining course requirements and support for herbaria are among the documented evidence. Yet costly mistakes in policy relating to natural resources, agriculture, and health might have been avoided by paying attention to organisms' natural history, and future policies will be improved if natural history knowledge is used and expanded. New technologies offer ways to increase natural history ...

Male Eurasian jays know that their female partners’ desires can differ from their own
Knowing what another person wants is not a trivial issue, particularly when the other's desires are different from our own. The ability to disengage from our own desire to cater to someone else's wishes is thought to be a unique feature of human cognition. New research challenges this assumption. Despite wanting something different to eat, male Eurasian jays can disengage from their own current desire in order to feed the female what she wants even when her desires are different to his.

Salamanders shrinking as their mountain havens heat up
Salamanders in some of North America's best habitat are shrinking fast as their surroundings get warmer and drier, forcing them to burn more energy. A new article examines specimens caught in the Appalachian Mountains from 1957 to 2007 and wild salamanders caught at the same sites in 2011-2012. Animals measured after 1980 averaged 8 percent smaller -- one of the fastest rates of changing body size ever recorded.

Understanding plant-soil interaction could lead to new ways to combat weeds
Using high-powered DNA-based tools, a recent study identified soil microbes that negatively affect ragweed and provided a new understanding of the complex relationships going on beneath the soil surface between plants and microorganisms. The study allowed researchers to observe how three generations of ragweed and sunflower interacted with the microbial community in the soil. The plants interact with each other indirectly due to the differing effects they each have on the microbes in the ...

Sugar, not oil: New possibilities for isobutene from wood sugar
No more oil – renewable raw materials are the future. This motto not only applies to biodiesel, but also to isobutene, a basic product used in the chemical industry. In a pilot plant researchers now want to obtain isobutene from sugar instead of oil for the first time. And in order not to threaten food supplies, in the long term the sugar should come from wood or straw and not from sugar beet.

Missing hormone in birds: Leptin found in mallard duck, peregrine falcon and zebra finch
How does the Arctic tern (a sea bird) fly more than 80,000 miles in its roundtrip North Pole-to-South Pole migration? How does the Emperor penguin incubate eggs for months during the Antarctic winter without eating? These physiological gymnastics would usually be influenced by leptin, the hormone that regulates body fat storage, metabolism and appetite. However, leptin has gone missing in birds -- until now.

Climate change will improve survival rates of British bird -- the long-tailed tit
Climate change may be bad news for billions, but scientists have discovered one unlikely winner -- a tiny British bird, the long-tailed tit. Like other small animals that live for only two or three years, these birds had until now been thought to die in large numbers during cold winters. But new research suggests that warm weather during spring instead holds the key to their survival.

Mother-of-pearl inspires super-strong material
Whether traditional or derived from high technology, ceramics all have the same flaw: they are fragile. Yet this characteristic may soon be a thing of the past: a team of researchers has recently presented a new ceramic material inspired by mother-of-pearl from the small single-shelled marine mollusk abalone.

Rocky mountain wildflower season lengthens by more than a month
A 39-year study of wildflower blooms in a Rocky Mountain meadow shows more than two-thirds of alpine flowers changed their blooming pattern in response to climate change. Half are beginning to bloom weeks earlier, more than a third are reaching peak bloom earlier, and others' last blooms are later. Records of more than two million blooms show flowering plants' response to climate change is more complex than previously believed. Species that depend on wildflowers are likely to be affected.

An end to animal testing for drug discovery?
As some countries and companies roll out new rules to limit animal testing in pharmaceutical products designed for people, scientists are stepping in with a new way to test therapeutic drug candidates and determine drug safety and drug interactions -- without using animals. The development of "chemosynthetic livers" could dramatically alter how drugs are made.

Global problem of fisheries bycatch needs global solutions
Whenever fishing vessels harvest fish, other animals can be accidentally caught or entangled in fishing gear as bycatch. Numerous strategies exist to prevent bycatch, but data have been lacking on the global scale of this issue. A new in-depth analysis of global bycatch data provides fisheries and the conservation community with the best information yet to help mitigate the ecological damage of bycatch and helps identify where mitigation measures are most needed.

Back to life after 1,500 years: Moss brought back to life after 1,500 years frozen in ice
Researchers have demonstrated that, after over 1,500 years frozen in Antarctic ice, moss can come back to life and continue to grow. For the first time, this vital part of the ecosystem in both polar regions has been shown to have the ability to survive century to millennial scale ice ages. This provides exciting new insight into the survival of life on Earth.

Forest corridors help plants disperse their seeds, study shows
A forest, a supercomputer and some glow-in-the-dark yarn have helped a team of field ecologists conclude that woodland corridors connecting patches of endangered plants not only increase seed dispersal from one patch to another, but also create wind conditions that can spread the seeds for much longer distances. An environmental engineer leveraged Ohio Supercomputer Center systems to simulate a forest and the winds that flow through it.
