Published Human ancestors preferred mosaic landscapes and high ecosystem diversity
(via sciencedaily.com) Original source A new study finds that early human species adapted to mosaic landscapes and diverse food resources, which would have increased our ancestor's resilience to past shifts in climate.
Published Nature is changing as land abandonment increases
(via sciencedaily.com) Original source Abandoned lands could be both an opportunity and a threat for biodiversity; a recent article highlights why abandoned lands are critical in the assessment of global restoration and conservation targets.
Published New study reveals boreal wetlands are a large source of reactive vapors in a warming climate
(via sciencedaily.com) Original source Boreal wetlands are a significant source of isoprene and terpenes, a class of highly reactive organic compounds that have a substantial impact on the Earth's climate, according to a new study.
Published Invading insect could transform Antarctic soils
(via sciencedaily.com) Original source A tiny flightless midge which has colonized Antarctica's Signy Island is driving fundamental changes to the island's soil ecosystem, a study shows.
Published Preserving pine forests by understanding beetle flight
(via sciencedaily.com) Original source Researchers study the flight performance of the mountain pine beetle from a fluid mechanics and an entomological perspective. Understanding these aspects of the insect's flight could improve estimates of its spread through the environment and preserve pine forests. To examine insect flight, the team employed a type of model previously used for idealized airfoils. They showed that it can be successfully applied to multiple individual animals across biological sex, insect age, and body size. In doing so, the model can predict how these factors impact flight characteristics.
Published Kangaroo Island ants 'play dead' to avoid predators
(via sciencedaily.com) Original source They're well known for their industrious work, but now a species of ant on Kangaroo Island is also showing that it is skilled at 'playing dead', a behavior that researchers believe is a recorded world first.
Published Water warming study shows unexpected impact on fish size
(via sciencedaily.com) Original source The theory that water-breathing animals such as fish will shrink due to global warming has been called into question by a new study.
Published Beetles and their biodiversity in dead wood
(via sciencedaily.com) Original source Which energy type promotes the biodiversity of beetles living in dead wood in the forest? That depends entirely on where the beetles are in the food chain.
Published Earth's first animals had particular taste in real estate
(via sciencedaily.com) Original source Even without body parts that allowed for movement, new research shows -- for the first time -- that some of Earth's earliest animals managed to be picky about where they lived.
Published Can a city store as much carbon as a forest?
(via sciencedaily.com) Original source A new tool helps show how growing cities can remain carbon neutral.
Published Exploring the underground connections between trees
(via sciencedaily.com) Original source Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
Published Tooth enamel provides clues to hunter-gatherer lifestyle of Neanderthals
(via sciencedaily.com) Original source A study has given an intriguing glimpse of the hunting habits and diets of Neanderthals and other humans living in western Europe.
Published Small wildlife surveys can produce 'big picture' results
(via sciencedaily.com) Original source Small-scale wildlife surveys can reveal the health of entire ecosystems, new research shows.
Published Viruses could reshuffle the carbon cycle in a warming world
(via sciencedaily.com) Original source The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and their microbial hosts. Their preliminary models show that viruses could alter carbon balance, causing some ecosystems to switch from net carbon sources to net carbon sinks.
Published Cleanup of inactive Gulf of Mexico wells estimated at $30 billion
(via sciencedaily.com) Original source A new article examines the cost to plug 14,000 wells that are inactive, have not produced for five years and are unlikely to be reactivated in the Gulf of Mexico region, which is the epicenter of U.S. offshore oil and gas operations.
Published First observational evidence of beaufort gyre stabilization, which could be precursor to huge freshwater release
(via sciencedaily.com) Original source A new study provides the first observational evidence of the stabilization of the anti-cyclonic Beaufort Gyre, which is the dominant circulation of the Canada Basin and the largest freshwater reservoir in the Arctic Ocean.
Published Symmetric graphene quantum dots for future qubits
(via sciencedaily.com) Original source Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists have now shown that bilayer graphene has even more to offer here than other materials. The double quantum dots they have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism -- one of the necessary criteria for quantum computing.
Published Archaea in a warming climate become less diverse, more predictable
(via sciencedaily.com) Original source Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.
Published Single approach on wild horses
(via sciencedaily.com) Original source Because contrasting societal views have created an approach that simultaneously manages horses on the range as wildlife, livestock and pets, current U.S. government programs are incapable of succeeding, according to researchers.
Published Scientists begin to unravel global role of atmospheric dust in nourishing oceans
(via sciencedaily.com) Original source New research begins to unravel the role dust plays in nourishing global ocean ecosystems while helping regulate atmospheric carbon dioxide levels.
