Published Australia's most at-risk bird species share some common traits
(via sciencedaily.com) Original source Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.
Published Compounds released by bleaching reefs promote bacteria, potentially stressing coral further
(via sciencedaily.com) Original source New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.
Published How ancient sea creatures can inform soft robotics
(via sciencedaily.com) Original source Fossils of a marine animal that lived 500 million years ago, combined with computer simulations, informed the design of a new soft robot.
Published Five dazzling new species of eyelash vipers discovered in Colombia and Ecuador
(via sciencedaily.com) Original source Scientists have discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador.
Published Researchers show classical computers can keep up with, and surpass, their quantum counterparts
(via sciencedaily.com) Original source A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Published Dinosaurs' success helped by specialized stance and gait, study finds
(via sciencedaily.com) Original source Dinosaurs' range of locomotion made them incredibly adaptable, researchers have found.
Published How kelp forests persisted through the large 2014-2016 Pacific marine heatwave
(via sciencedaily.com) Original source New research reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures.
Published Floating algae a raft for juvenile pelagic fish
(via sciencedaily.com) Original source Floating macroalgal acts as a raft that provides habitat for a diverse array of juvenile oceanic fish a new study has found. The study conducted in the Ningaloo Coast World Heritage Area, Western Australia, revealed that fish were more abundant around macroalgal rafts than in open water, with eleven species of juvenile fishes associated with Sargassum rafts, and one species of both juveniles and adults.
Published Endangered seabird shows surprising individual flexibility to adapt to climate change
(via sciencedaily.com) Original source New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.
Published Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries
(via sciencedaily.com) Original source Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.
Published Unexpected biodiversity on the ocean floor
(via sciencedaily.com) Original source Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Ancient brown bear genomes sheds light on Ice Age losses and survival
(via sciencedaily.com) Original source The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?
Published Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat
(via sciencedaily.com) Original source Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.
Published Three-year population study supports fight to save Cameroon's Kordofan giraffe
(via sciencedaily.com) Original source Crucial new data about the numbers of Critically Endangered Kordofan giraffe living within Cameroon's B nou National Park has been released, supporting conservation efforts to save the subspecies from extinction.
Published Health researchers develop software to predict diseases
(via sciencedaily.com) Original source IntelliGenes analyzes genomic data to discover biomarkers associated with health traits.
Published A new perspective on the temperature inside tropical forests
(via sciencedaily.com) Original source New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.
Published The megalodon was less mega than previously believed
(via sciencedaily.com) Original source A new study shows the Megalodon, a gigantic shark that went extinct 3.6 million years ago, was more slender than earlier studies suggested. This finding changes scientists' understanding of Megalodon behavior, ancient ocean life, and why the sharks went extinct.
Published Sea otters helped prevent widespread California kelp forest declines over the past century
(via sciencedaily.com) Original source The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.
Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird
(via sciencedaily.com) Original source The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Why animals shrink over time explained with new evolution theory
(via sciencedaily.com) Original source The new theoretical research proposes that animal size over time depends on two key ecological factors.
