Published New deep learning AI tool helps ecologists monitor rare birds through their songs
(via sciencedaily.com) Original source Researchers have developed a new deep learning AI tool that generates life-like birdsongs to train bird identification tools, helping ecologists to monitor rare species in the wild.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Geese 'keep calm and carry on' after deaths in the flock
(via sciencedaily.com) Original source Canada geese strengthen existing friendships and forge a few new connections after losing close associates from their flock, new research shows.
Published Non-native species likely to continue spreading in North America, Australia and Europe
(via sciencedaily.com) Original source Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published Research provides crucial insights into moss growth under elevated CO2 levels that may benefit climate change models
(via sciencedaily.com) Original source Approximately 12,000 species of mosses exist and cover close to four million square miles of earth, equivalent to the size of Canada, and are ecologically and evolutionarily important. Mosses play an essential role in rainwater retention, decreasing plant pathogens and increasing carbon sequestration in soil, thus improving the overall soil health. Mosses also protect long-term carbon storage systems, such as bogs and permafrost.
Published Template for success: Shaping hard carbon electrodes for next-generation batteries
(via sciencedaily.com) Original source Sodium- and potassium-ion batteries are promising next-generation alternatives to the ubiquitous lithium-ion batteries (LIBs). However, their energy density still lags behind that of LIBs. To tackle this issue, researchers explored an innovative strategy to turn hard carbon into an excellent negative electrode material. Using inorganic zinc-based compounds as a template during synthesis, they prepared nanostructured hard carbon, which exhibits excellent performance in both alternative batteries.
Published Naturally regrowing forests are helping to protect the remaining old forests in the Amazon
(via sciencedaily.com) Original source Secondary forests that have regrown naturally on land abandoned from agriculture are important in counteracting the effects of forest fragmentation across the Amazon basin, according to new findings.
Published Diverse forests hold huge carbon potential, as long as we cut emissions
(via sciencedaily.com) Original source New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.
Published Bacteria-virus arms race provides rare window into rapid and complex evolution
(via sciencedaily.com) Original source Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria and viruses, researchers are documenting rapid evolutionary processes in simple laboratory flasks in only three weeks.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com) Original source Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published A fifth of European Red List flora and fauna species may be at risk of extinction
(via sciencedaily.com) Original source A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.
Published Feral horses and peatland carbon emissions
(via sciencedaily.com) Original source A ground-breaking new study has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken
(via sciencedaily.com) Original source Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.
Published 'Alien' wasps thriving in tropical forests
(via sciencedaily.com) Original source Researchers say they have discovered high diversity of Darwin wasps in a tropical rainforest in Brazil, wasps which were previously thought to thrive more in cooler habitats.
Published Maps reveal biochar's potential for mitigating climate change
(via sciencedaily.com) Original source Twelve countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%.
Published Cracking the code: Genome sequencing reveals why songbirds are larger in colder climates
(via sciencedaily.com) Original source Scientists have unlocked the genetic basis underlying the remarkable variation in body size observed in song sparrows, one of North America's most familiar and beloved songbirds. This discovery also provides insights into this species' capacity to adapt to the challenges of climate change. The study used genomic sequencing to successfully pinpoint eight genetic variants, or DNA mutations, largely responsible for the nearly threefold difference in body size observed across the song sparrow range from Mexico to Alaska.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published A database unifies the information on damage to European forests over the last 60 years
(via sciencedaily.com) Original source Researchers are creating a database that harmonizes the recording of disturbances caused by insects and diseases in forests in 8 European countries by combining remote sensing, satellite images and field data.
