Published Assessing emotions in wild animals
(via sciencedaily.com) Original source A new study examines indicators of mental wellbeing in wild animals to improve conservation efforts.
Published Butterflies on the decline
(via sciencedaily.com) Original source Research shows that the numbers of butterflies in meadows and pastures of Europe are in a continuous decline. Grassland butterflies will soon play an even greater role in EU nature conservation legislation. Based on the occurrences and population trends of butterflies, the member states are supposed to document the progress they have made in implementing the planned 'Nature Restoration Law'.
Published African smoke over the Amazon
(via sciencedaily.com) Original source Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.
Published About 13,000 years ago, the water outflow from the Mediterranean to the Atlantic Ocean was twice that of today’s
(via sciencedaily.com) Original source About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across the Mediterranean basin, which had a major impact on terrestrial and marine ecosystems. But what do we know about the impact of this climate change on water circulation in the Mediterranean?
Published We now know exactly what happens in nature when we fell forests
(via sciencedaily.com) Original source Deforestation is the biggest threat to the planet's ecosystems, and new research has now mapped out exactly what happens when agriculture replaces forestry.
Published Great Basin: History of water supply in one of the driest regions in the USA
(via sciencedaily.com) Original source An international team has reconstructed the evolution of groundwater in the Great Basin, USA -- one of the driest regions on Earth -- up to 350,000 years into the past with unprecedented accuracy. The results shed new light on the effects of climate change on water supply and provide important insights for the sustainable use of groundwater resources.
Published Global warming puts whales in the Southern Ocean on a diet
(via sciencedaily.com) Original source In the autumn, when right whales swim towards the coasts of South Africa, they ought to be fat and stuffed full. But in recent years, they have become thinner because their food is disappearing with the melting sea ice.
Published Scientists discover fire records embedded within sand dunes
(via sciencedaily.com) Original source A new study shows that sand dunes can serve as repositories of fire history and aid in expanding scientific understanding of fire regimes around the world.
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.
