Published Short-distance migration critical for climate change adaptation
(via sciencedaily.com) Short-distance migration, which accounts for the vast majority of migratory movements in the world, is crucial for climate change adaptation, according to new research. Contrary to common assumptions, most migratory movements are people moving short distances, largely due to economic, social and environmental factors, such as climate change.
Published Plant roots fuel tropical soil animal communities
(via sciencedaily.com) A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.
Published Pioneering study shows flood risks can still be considerably reduced if all global promises to cut carbon emissions are kept
(via sciencedaily.com) Annual damage caused by flooding in the UK could increase by more than a fifth over the next century due to climate change unless all international pledges to reduce carbon emissions are met, according to new research.
Published Mineral particles and their role in oxygenating the Earth's atmosphere
(via sciencedaily.com) Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
Published Mississippi River Delta study reveals which human actions contribute to land loss
(via sciencedaily.com) Scientists reveal new information about the role humans have played in large-scale land loss in the Mississippi River Delta -- crucial information in determining solutions to the crisis.
Published Phone-based measurements provide fast, accurate information about the health of forests
(via sciencedaily.com) Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods.
Published Sea level rise poses particular risk for Asian megacities
(via sciencedaily.com) Original source Sea level rise this century may disproportionately affect certain Asian megacities, according to new research that looks at the effects of natural sea level fluctuations in addition to climate change. The study identified several Asian megacities that may face especially significant risks by 2100, including Chennai, Kolkata, Yangon, Bangkok, Ho Chi Minh City, and Manila.
Published Ocean surface tipping point could accelerate climate change
(via sciencedaily.com) Original source A study has found that intense global warming could shut down the ocean's ability to soak up carbon dioxide, leading to accelerated global warming as the greenhouse gas accumulates in the atmosphere. The decline happens because of a surface layer of low-alkalinity water that emerges during extreme warming that hinders the ability of the oceans to absorb CO2. The study is based on a climate simulation configured to a worst-case emissions scenario that the researchers say must be avoided at all costs.
Published Catalyst purifies herbicide-tainted water and produces hydrogen
(via sciencedaily.com) Researchers have developed a dual-purpose catalyst that purifies herbicide-tainted water while also producing hydrogen.
Published U.S. birds' Eastern, Western behavior patterns are polar opposites
(via sciencedaily.com) Scientists have established what could be considered a baseline map of annual avian functional and species diversity patterns in the U.S., finding that functional diversity patterns in the West, where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high.
Published Mulching time of forest meadows influences insect diversity
(via sciencedaily.com) Researchers have examined how mulching at different times affects insect flower-visitors and larvae.
Published Deforestation in the tropics linked to a reduction in rainfall
(via sciencedaily.com) Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published Flower power: The role of ants in forest regeneration
(via sciencedaily.com) Ants play a key role in forest regeneration, according to a new article.
Published Australia's rarest bird of prey disappearing at alarming rate
(via sciencedaily.com) Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'
(via sciencedaily.com) By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Insect bite marks show first fossil evidence for plants' leaves folding up at night
(via sciencedaily.com) Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.
Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Clever orchard design for more nuts
(via sciencedaily.com) To reduce biodiversity loss in agricultural landscapes, more sustainable and environmentally friendly agricultural practices are needed. A research team has investigated how ecosystem services such as pollination could be improved in macadamia plantations. The scientists showed that a certain design of plantations -- for instance, how the rows of trees are arranged, the varieties, and the integration of semi-natural habitats in and around the plantations -- can increase the pollination performance of bees.
Published A fifth of California's Sierra Nevada conifer forests are stranded in habitats that have grown too warm for them
(via sciencedaily.com) Researchers created maps showing where warmer weather has left trees in conditions that don't suit them, making them more prone to being replaced by other species. The findings could help inform long-term wildfire and ecosystem management in these 'zombie forests.'
Published Climate 'spiral' threatens land carbon stores
(via sciencedaily.com) The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.
