Published Strongest Arctic cyclone on record led to surprising loss of sea ice
(via sciencedaily.com) The strongest Arctic cyclone ever observed struck in January 2022. A new analysis shows that while forecasts accurately predicted the massive storm, models seriously underestimated its effect on sea ice. Results suggest where forecast models for a changing Arctic Ocean could improve.
Published 1930s Dust Bowl led to extreme heat around Northern Hemisphere
(via sciencedaily.com) The 1930s Dust Bowl affected heat extremes across much of North America and as far away as Europe and East Asia, according to new research. The study found that the extreme heating of the Great Plains triggered motions of air around the Northern Hemisphere in ways that suppressed cloud formation in some regions and contributed to record heat thousands of miles away.
Published Mangroves: Environmental guardians of our coastline
(via sciencedaily.com) They are the salt-tolerant shrubs that thrive in the toughest of conditions, but according to new UniSA research, mangroves are also avid coastal protectors, capable of surviving in heavy metal contaminated environments.
Published Forests benefit from tree species variety and genetic diversity
(via sciencedaily.com) Original source Reforestation projects should include a variety of tree species and ensure genetic diversity within each species to maximize new forests' health and productivity.
Published Plastic additives contaminate the sea and selectively harm corals' reproduction processes, research finds
(via sciencedaily.com) A new study examined the effect of plastic additives on the reproductive process and larvae development of corals and other organisms commonly found in the coral reef of Eilat.
Published Researchers discover root exudates have surprising and counterintuitive impact on soil carbon storage
(via sciencedaily.com) Researchers examined root exudates and their impact on soil carbon storage revealing surprising and counterintuitive results.
Published Biodiversity in Africa and Latin America at risk from oil palm expansion, new report warns
(via sciencedaily.com) Zero deforestation commitments may inadvertently leave vital habitats in Latin America and Africa vulnerable to agricultural expansion, a new study has found.
Published Animals are key to restoring the world's forests
(via sciencedaily.com) Original source By dispersing seeds, animals can rapidly reestablish plant diversity in degraded forests.
Published Less intensively managed grasslands have higher plant diversity and better soil health
(via sciencedaily.com) Researchers have shown -- for the first time -- that less intensively managed British grazed grasslands have on average 50% more plant species and better soil health than intensively managed grassland. The new study could help farmers increase both biodiversity and soil health, including the amount of carbon in the soil of the British countryside.
Published Corals saving corals
(via sciencedaily.com) Corals resistant to disease can rescue more vulnerable corals, UC Davis found. Raising corals with diverse genotypes builds resilience amid disease and climate changes in reefs.
Published Arctic carbon conveyor belt discovered
(via sciencedaily.com) Every year, the cross-shelf transport of carbon-rich particles from the Barents and Kara Seas could bind up to 3.6 million metric tons of CO2 in the Arctic deep sea for millennia. In this region alone, a previously unknown transport route uses the biological carbon pump and ocean currents to absorb atmospheric CO2 on the scale of Iceland's total annual emissions, as researchers report.
Published Crown-of-thorns seastar from Red Sea is endemic species
(via sciencedaily.com) Researchers have identified coral-eating crown-of-thorns seastars in the Red Sea as distinct species that occurs only in this location.
Published Deadly coral disease in Florida, Caribbean may be transported in ship hulls, study finds
(via sciencedaily.com) A new study suggests that ships may be spreading a deadly coral disease across Florida and the Caribbean. The findings could help establish testing and treatment methods to mitigate the risk of further disease spread.
Published Arctic vegetation has a major impact on warming
(via sciencedaily.com) An international team of research scientists has documented the central role of vegetation for Arctic warming. The new results allow us to make more precise climate predictions, with the researchers pointing out that current models remain flawed.
Published Exploring the possibility of extraterrestrial life living in caves
(via sciencedaily.com) For millennia, caves have served as shelters for prehistoric humans. Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.
Published Ray of hope? One place where reef manta rays are thriving
(via sciencedaily.com) Over a decade, manta ray populations increased significantly in Raja Ampat archipelago in Indonesia, highlighting the importance of long-term conservation and management measures such as well-enforced Marine Protected Areas (MPAs) and fisheries regulations, says a researcher.
Published Desert dust collected from glacier ice helps document climate change
(via sciencedaily.com) Researchers are using dust trapped in glacier ice in Tibet to document past changes in Earth's intricate climate system -- and maybe one day help predict future changes.
Published Researchers produce first-ever 'family tree' for aquarium-bred corals
(via sciencedaily.com) The first-ever family tree for aquarium-bred corals provides insights for maximizing genetic diversity and adaptability in corals bred for conservation.
Published Scientists say sea-level changes formed Australia's K'Gari Sand Island, Great Barrier Reef
(via sciencedaily.com) Researchers report evidence the formation of K'gari and the Great Barrier Reef are linked to a change in the magnitude of sea-level rise and fall due to major climate feedback changes during the Middle Pleistocene Transition.
Published Half of replanted tropical trees don't survive
(via sciencedaily.com) Original source On average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years, but there is enormous variation in outcomes, new research has found.
