Published Spy-satellite images offer insights into historical ecosystem changes
(via sciencedaily.com) Original source New study advocates the use of more than one million declassified images for ecology and conservation. The images can offer better insights into the historical changes of ecosystems, species populations or changes in human influences on the environment dating back to the 1960s. Collaboration between ecologists, conservationists, and remote sensing experts is necessary to explore the full potential of the data.
Published Scientists may have cracked the 'aging process' in species
(via sciencedaily.com) Original source Research shows the relationship between a species' age and its risk of going extinct could be accurately predicted by an ecological model called the 'neutral theory of biodiversity.'
Published First-ever report of nesting of incredibly rare and endangered giant turtle
(via sciencedaily.com) Original source Knowledge from local communities has resulted in the first-ever nesting evidence and discovery of a breeding population of an incredibly rare turtle in India.
Published Genetic insights and conservation challenges of Nara's sacred deer
(via sciencedaily.com) Original source In Nara, Japan, the revered sika deer faces a dilemma as their escalating population damages local farmlands. A new study has revealed a complex situation: while the sanctuary's deer upholds a distinct genetic identity, the surrounding areas display a blend of genetic lineages. This exposes a pressing predicament: whether to cull the 'pest' deer around sanctuary or risk losing a sacred genetic legacy.
Published Pollinator's death trap turns into nursery
(via sciencedaily.com) Original source In a group of plants that is famous for luring its pollinators into a death trap, one species offers its flowers as a nursery in exchange. The discovery blurs the line between mutualism and parasitism and sheds light on the evolution of complex plant-insect interactions.
Published Viruses that can help 'dial up' carbon capture in the sea
(via sciencedaily.com) Original source Armed with a catalog of hundreds of thousands of DNA and RNA virus species in the world's oceans, scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar techniques, different viruses that may prevent methane's escape from thawing Arctic soil.
Published Online digital data and AI for monitoring biodiversity
(via sciencedaily.com) Original source Researchers propose a framework for integrating online digital data into biodiversity monitoring.
Published How is deforested land in Africa used?
(via sciencedaily.com) Original source Africa's forested areas -- an estimated 14 % of the global forest area -- are continuing to decline at an increasing rate -- mostly because of human activities to convert forest land for economic purposes. As natural forests are important CO2 and biodiversity reservoirs, this development has a significant impact on climate change and effects the integrity of nature.
Published Reforestation programs could threaten vast area of tropical grasslands
(via sciencedaily.com) Original source New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.
Published Big new idea introduced with the help of tiny plankton
(via sciencedaily.com) Original source A new model bridges the rules of life at the individual scale and the ecosystem level, which could open new avenues of exploration in ecology, global change biology, and ultimately ecosystem management.
Published A lighthouse in the Gobi desert
(via sciencedaily.com) Original source A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
Published Scientists are unravelling the secrets of red and grey squirrel competition
(via sciencedaily.com) Original source Researchers have identified significant differences between the diversity of gut bacteria in grey squirrels compared to red squirrels which could hold the key to further understanding the ability of grey squirrels to outcompete red squirrels in the UK.
Published Climate change drove the emergence of West Nile virus in Europe
(via sciencedaily.com) Original source Researchers demonstrate the contribution of climate change to the spatial expansion of West Nile virus in Europe, a virus that constitutes a new public health threat in the continent. Their findings highlight a notable increase in the area ecologically suitable for the virus circulation since the beginning of last century and an increase in the human population at risk of exposure, due in part to climate change.
Published Love songs lead scientists to new populations of skywalker gibbons in Myanmar
(via sciencedaily.com) Original source The love songs of the Skywalker gibbon alerted scientists to a new population of the endangered primate in Myanmar.
Published Is the Amazon forest approaching a tipping point?
(via sciencedaily.com) Original source Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.
Published A century of reforestation helped keep the eastern US cool
(via sciencedaily.com) Original source Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.
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 The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly
(via sciencedaily.com) Original source Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
Published Global deforestation leads to more mercury pollution
(via sciencedaily.com) Original source Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.
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.
