Published How technology and economics can help save endangered species
(via sciencedaily.com) Original source A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Five new species of soft-furred hedgehogs from Southeast Asia
(via sciencedaily.com) Original source A new study identifies five new species of soft-furred hedgehogs from Southeast Asia. The study used DNA analysis and physical characteristics to describe two entirely new species of soft-furred hedgehogs and elevate three subspecies to the level of species.
Published Insects already had a variety of defense strategies in the Cretaceous
(via sciencedaily.com) Original source Analyses of amber show that insect larvae were already using a wide variety of tactics to protect themselves from predators 100 million years ago.
Published How national policies affect forests in border regions
(via sciencedaily.com) Original source How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Tree plantations can get better with age -- but original habitats are best
(via sciencedaily.com) Original source Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.
Published World's smallest 'fanged' frogs found in Indonesia
(via sciencedaily.com) Original source Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.
Published Machine learning boosts search for new materials
(via sciencedaily.com) Original source During X-ray diffraction experiments, bright lasers shine on a sample, producing diffracted images that contain important information about the material's structure and properties. But conventional methods of analyzing these images can be contentious, time-consuming, and often ineffective, so scientists are developing deep learning models to better leverage the data.
Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com) Original source Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published 15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems
(via sciencedaily.com) Original source Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
Published Ecosystem benefits to humanity expected to decline by 9% by 2100
(via sciencedaily.com) Original source A new study of natural capital finds nature's benefits to humanity are expected to decline as climate change shifts ecosystems across borders.
Published Coral atoll islands may outpace sea-level rise with local ecological restoration, scientists say
(via sciencedaily.com) Original source Ecological restoration may save coral atoll islands from the rising seas of climate change, according to an international team of scientists, conservationists, and an indigenous leader.
Published How can Europe restore its nature?
(via sciencedaily.com) Original source Early 2024, the European Parliament will take a final vote on the 'Nature Restoration Law' (NRL), a globally unique but hotly debated regulation that aims to halt and reverse biodiversity loss in Europe. An international team of scientists has investigated the prospects of the new regulation.
Published Newly developed material gulps down hydrogen, spits it out, protects fusion reactor walls
(via sciencedaily.com) Original source A recent advance could enable more efficient compact fusion reactors that are easier to repair and maintain.
Published Move over Blitzen: Geese outpace reindeer impacts on Arctic ecosystems
(via sciencedaily.com) Original source A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands.
Published How forests smell -- a risk for the climate?
(via sciencedaily.com) Original source Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.
Published Extracting uranium from seawater as another source of nuclear fuel
(via sciencedaily.com) Original source Oceans cover most of Earth's surface and support a staggering number of lifeforms, but they're also home to a dilute population of uranium ions. And -- if we can get these particular ions out of the water -- they could be a sustainable fuel source to generate nuclear power. Researchers have now developed a material to use with electrochemical extraction that attracts hard-to-get uranium ions from seawater more efficiently than existing methods.
Published Aquatic insects in restored streams need more rocks to lay their eggs
(via sciencedaily.com) Original source Likening it to providing more runways at busy airports, researchers at North Carolina State University found in a new study that adding protruding rocks to restored streams can help attract female aquatic insects that lay their eggs on the rock bottoms or sides.
Published Twenty-year study confirms California forests are healthier when burned -- or thinned
(via sciencedaily.com) Original source A 20-year experiment in the Sierra Nevada confirms that different forest management techniques -- prescribed burning, restoration thinning or a combination of both -- are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.
Published The configuration of green spaces in cities determines the characteristics of their birds
(via sciencedaily.com) Original source An international study has analyzed the distribution of 115 species of birds in spring and 72 that spend the winter in different cities. The study provides information on how to design urban areas that favor biodiversity and public wellbeing.
Published Suburban backyard home to more than 1,000 species
(via sciencedaily.com) Original source A challenge among three housemates to identify species around their inner-Brisbane home has resulted in an academic research paper, showcasing the rich biodiversity in urban landscapes.
