Published Researchers develop grassroots framework for managing environmental commons
(via sciencedaily.com) Original source A team of sustainability scientists recently announced that they have developed a community-based framework, founded on extensive local and traditional knowledge, to help assess and respond to the kinds of ecological threats that are widely dispersed across a varied landscape and whose solutions are not immediately obvious. The framework, which was developed to address watershed issues in Honduras's Lake Yojoa, is widely applicable to a broad range of threats facing ecological commons wherever they may occur around the world.
Published Top 10 climate science insights unveiled
(via sciencedaily.com) Original source A new report equips policymakers with the latest and most pivotal climate science research from the previous 18 months, synthesized to help inform negotiations at COP28 and policy implementation through 2024 and beyond.
Published In hotter regions, mammals seek forests, avoid human habitats
(via sciencedaily.com) Original source As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.
Published Public gardens contribute to invasives problem
(via sciencedaily.com) Original source Some nonnative plants cultivated in public gardens or arboretums are escaping to become invasive in wild forests.
Published Botany must feature more prominently on the school curriculum to promote awareness of climate change, study warns
(via sciencedaily.com) Original source Children must be taught more about the importance of plants if education about climate change and sustainability is to be effective, experts have warned.
Published One of the largest magnetic storms in history quantified: Aurorae covered much of the night sky from the Tropics to the Polar Regions
(via sciencedaily.com) Original source An international multidisciplinary team consisting of solar physicists, geophysicists, and historians from nine countries analysed observations of an extreme solar-terrestrial storm reported in historical records from February 1872. Their findings confirm that a moderate sunspot group triggered one of the largest magnetic storms ever recorded, almost covering the entire night sky with colourful aurorae in both hemispheres. If such an extreme storm occurred today, it would severely disrupt modern technological infrastructure. Their study emphasizes the importance of looking at historical records in light of modern scientific knowledge.
Published Rare ant species rediscovered in North Carolina trees
(via sciencedaily.com) Original source There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.
Published Inoculation against diseased fields
(via sciencedaily.com) Original source Farmland often harbors a multitude of pathogens which attack plants and reduce yields. A research team has now shown that inoculating the soil with mycorrhizal fungi can help maintain or even improve yields without the use of additional fertilizers or pesticides. In a large-scale field trial, plant yield increased by up to 40 percent.
Published Landscape dynamics determine the evolution of biodiversity on Earth
(via sciencedaily.com) Original source A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.
Published Flower power on Indian farms helps bees and boosts livelihoods
(via sciencedaily.com) Original source Planting flowers beside food crops on farms in India attracts bees, boosts pollination and improves crop yield and quality, researchers have found.
Published Solar activity likely to peak next year
(via sciencedaily.com) Original source Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.
Published Slash-and-burn agriculture can increase forest biodiversity, researchers find
(via sciencedaily.com) Original source The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.
Published Sensitive ecosystems at risk from mine waste
(via sciencedaily.com) Original source Nearly a third of the world's mine tailings are stored within or near protected conservation areas, new research has found.
Published Protect delicate polar ecosystems by mapping biodiversity
(via sciencedaily.com) Original source Concerted action is required to mitigate the impact of warming on polar ecosystems and sustainably manage these unique habitats.
Published Nature photographers posting to social media help with protecting biodiversity
(via sciencedaily.com) Original source Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.
Published New study reveals huge potential for future waves of invasive species
(via sciencedaily.com) Original source Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
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 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 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.
