Published Coloring microscopic coral larvae to aid tracking for conservation and reef restoration
(via sciencedaily.com) A new, low-cost staining method enables visual tracking of coral larvae as they disperse and settle in coral reefs, according to a study.
Published Researchers propose new structures to harvest untapped source of freshwater
(via sciencedaily.com) An almost limitless supply of fresh water exists in the form of water vapor above Earth's oceans, yet remains untapped, researchers said. A new study suggests an investment in new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.
Published Forest resilience linked with higher mortality risk in western US
(via sciencedaily.com) Original source A forest's resilience, or ability to absorb environmental disturbances, has long been thought to be a boost for its odds of survival against the looming threat of climate change. But a new study suggests that for some Western U.S. forests, it's quite the opposite. The results of one of the first large-scale studies of its kind show that while high ecosystem resilience correlates with low mortality in eastern forests, it is linked to high mortality in western regions.
Published Climate change in the forests of northern Germany
(via sciencedaily.com) Original source More and more trees are suffering the consequences of decades of human-made climate change. The growth of the European beech has so far suffered decline mainly in southern Europe. European beech is Germany's most important native forest tree species and it is most commonly found in Central Europe. A research team has now been able to show that the European beech is suffering from increasing drought stress in summer in northern Germany as well. This climate stress is particularly pronounced at warmer sites, when there is a higher density of these trees together, and on very sandy soils.
Published Complete picture of Arctic sea ice freeze-thaw cycle highlights sea ice response to climate change
(via sciencedaily.com) Years of research show that climate change signals are amplified in the Arctic, and that sea ice in this region is sensitive to increases in Arctic warming. Sea ice greatly modifies the exchanges of heat, momentum and mass between the atmosphere and the ocean. So, the timings of the sea ice melt and freeze onsets, as well as the length of the melt and freeze seasons, play a key role in the 'heat budget' of the atmosphere-ice-ocean system.
Published Hibernating corals and the microbiomes that sustain them
(via sciencedaily.com) What happens to a coral's microbiome while it hibernates? A new study found microbial communities shift while a coral sleeps, which may inform coral health and recovery efforts.
Published Old-growth trees more drought tolerant than younger ones, providing a buffer against climate change
(via sciencedaily.com) Original source A new analysis of more than 20,000 trees on five continents shows that old-growth trees are more drought tolerant than younger trees in the forest canopy and may be better able to withstand future climate extremes. The findings highlight the importance of preserving the world's remaining old-growth forests, which are biodiversity strongholds that store vast amounts of planet-warming carbon, according to forest ecologists.
Published 'Digital footprints' central to new approach for studying post-disturbance recreation changes
(via sciencedaily.com) A new social media-based study of recreation visitation in the Gorge following the Eagle Creek Fire expands on research launched in 2016 -- and holds promise for other large, multi-ownership landscapes. The study shows how using new approaches that draw from social media data can help us better understand the complex relationships between wildfire, natural resource management, and people.
Published Major fires an increasing risk as the air gets thirstier, research shows
(via sciencedaily.com) Greater atmospheric demand for water means a dramatic increase in the risk of major fires in global forests unless we take urgent and effective climate action, new research finds. Researchers have examined global climate and fire records in all of the world's forests over the last 20 years.
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 When cyclones and fires collide...
(via sciencedaily.com) As strong winds and torrential rains inundate Australia's south-eastern coast, new research suggests that high intensity bushfires might not be too far behind, with their dual effects extending damage zones and encroaching on previously low-risk residential areas.
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.
