Published By air, rain and land: How microbes return after a wildfire
(via sciencedaily.com) Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.
Published Efficient fuel-molecule sieving using graphene
(via sciencedaily.com) A research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.
Published How climate warming could disrupt a deep-rooted relationship
(via sciencedaily.com) Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.
Published Predicting the sustainability of a future hydrogen economy
(via sciencedaily.com) As renewable energy sources like wind and solar ramp up, they can be used to sustainably generate hydrogen fuel. But implementing such a strategy on a large scale requires land and water dedicated to this purpose.
Published Monkeys cause a stink in response to human noise
(via sciencedaily.com) Original source New research has found that monkeys increase their use of scent markings to compensate for human noise pollution. The study has investigated how primates change their communication strategies in response to noise pollution. The researchers studied endangered pied tamarins (Saguinus bicolor), which use both vocal calls and scent markings. The researchers found that the frequency of scent marking directly increased in line with noise decibel levels.
Published Sustainable energy for aviation: What are our options?
(via sciencedaily.com) Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.
Published Predictive model could improve hydrogen station availability
(via sciencedaily.com) Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers.
Published Incubator or barrier? Exploring the links between agriculture, biodiversity and the spread of pathogens
(via sciencedaily.com) Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.
Published Almost half of koala habitats will be under high bushfire threat by 2070
(via sciencedaily.com) The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration
(via sciencedaily.com) • Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
Published Scientists find good places to grow long-spined sea urchins, a starting point to restore 'the lawn mowers of the reefs'
(via sciencedaily.com) Scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. Researchers have identified algae on which larval sea urchins grow into juveniles in a lab setting.
Published More Texas owls are testing positive for rat poisons
(via sciencedaily.com) New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.
Published Freshwater connectivity can transport environmental DNA through the landscape
(via sciencedaily.com) A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published Plant-based food alternatives could support a shift to global sustainability
(via sciencedaily.com) Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.
Published Ecology and artificial intelligence: Stronger together
(via sciencedaily.com) Many of today's artificial intelligence systems loosely mimic the human brain. In a new paper, researchers suggest that another branch of biology -- ecology -- could inspire a whole new generation of AI to be more powerful, resilient, and socially responsible. The paper argues for a synergy between AI and ecology that could both strengthen AI and help to solve complex global challenges, such as disease outbreaks, loss of biodiversity, and climate change impacts.
Published Art, science merge in study of 19th-century landscape paintings' ecological integrity
(via sciencedaily.com) A collaboration of ecologists and art historians has demonstrated that landscape paintings from more than 150 years ago can advance environmental science.
Published Scientists find evidence of sea star species hybridization
(via sciencedaily.com) A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Invasive alien species play key role in 60% of global plant and animal extinctions
(via sciencedaily.com) A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published New study reveals the power of railroads to buffer coal plants from a carbon emissions tax
(via sciencedaily.com) A new study suggests that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources.
Published Lack of evidence hampers progress on corporate-led ecosystem restoration
(via sciencedaily.com) An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.
