Published Without aggressive climate action, U.S. property values will take a hit from escalating wildfire risk and tree mortality, study finds
(via sciencedaily.com) Original source Research attempts to quantify the value of U.S. property at risk in forested areas exposed to increased ecological disturbance associated with climate change, such as wildfire and tree mortality. Property exposed to such climate risks, especially in California, is project to climb substantially if emission-reduction measures are not taken.
Published In the treetops: Ecologist studies canopy soil abundance, chemistry
(via sciencedaily.com) Original source Ecologists examined the distribution patterns of canopy soils, and their soil properties, across Costa Rican forests. The researchers suggest canopy soil may store more carbon than previously thought. Consideration of the time needed for reforestation of system with tree canopies should include the time needed for canopy mat regrowth.
Published Tropical trees use social distancing to maintain biodiversity
(via sciencedaily.com) Original source Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
Published Plans to plant billions of trees threatened by massive undersupply of seedlings
(via sciencedaily.com) Original source Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.
Published New study reveals that tree species diversity increases spider density
(via sciencedaily.com) Original source The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published Research supports use of managed and prescribed fires to reduce fire severity
(via sciencedaily.com) Original source Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.
Published Miocene period fossil forest of Wataria found in Japan
(via sciencedaily.com) Original source An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.
Published Gene variation makes apple trees 'weep,' improving orchards
(via sciencedaily.com) Original source Plant geneticists have identified a mutation in a gene that causes the 'weeping' architecture -- branches growing downwards -- in apple trees, a finding that could improve orchard fruit production.
Published Building a better forest tree with CRISPR gene editing
(via sciencedaily.com) Original source Researchers use CRISPR techniques to modify lignin levels in poplar trees.
Published Forest can adapt to climate change, but not quickly enough
(via sciencedaily.com) Original source America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.
Published Study reveals how a tall spruce develops defense against hungry weevils
(via sciencedaily.com) Original source A study has identified genes involved in development of stone cells -- rigid cells that can block a nibbling insect from eating budding branches of the Sitka spruce evergreen tree. The insect's attack has stunted the growth of these forest giants.
Published Biotechnology offers holistic approach to restoration of at-risk forest tree species
(via sciencedaily.com) Original source Many at-risk forest tree species will probably need biotechnology along with traditional tree-breeding approaches to survive, according to new insights.
Published A seed survival story: How trees keep 'friends' close and 'enemies' guessing
(via sciencedaily.com) Original source A new study that included millions of tree-year observations worldwide for the first time documents and analyzes the intricate balance between seed defense and dispersal by forest trees at a global scale.
Published Mountains vulnerable to extreme rain from climate change
(via sciencedaily.com) Original source A new study finds that as rising global temperatures shift snow to rain, mountains across the Northern Hemisphere will be hotspots for extreme rainfall events that could trigger floods and landslides -- potentially impacting a quarter of the world's population.
Published This self-driving boat maps underwater terrain
(via sciencedaily.com) Original source Engineers concoct an easier way for scientists to study underwater topography.
Published Emulating how krill swim to build a robotic platform for ocean navigation
(via sciencedaily.com) Original source Researchers have presented important first steps in building underwater navigation robots.
Published Research in a place where geological processes happen before your eyes
(via sciencedaily.com) Original source Taiwan experiences some of the world's fastest rates of mountain building -- they are growing at a faster rate than our fingernails grow in a year. The mountains also see frequent and significant earthquakes, the region experiences about four typhoons per year on average, and in some places, it receives upwards of several meters of rain annually.
Published Don't wait, desalinate: A new approach to water purification
(via sciencedaily.com) Original source A water purification system separates out salt and other unnecessary particles with an electrified version of dialysis. Successfully applied to wastewater with planned expansion into rivers and seas, the method saves money and saps 90% less energy than its counterparts.
Published Study of Earth's stratosphere reduces uncertainty in future climate change
(via sciencedaily.com) Original source New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the Earth's surface. Future increases in water vapor here risk amplifying climate change and slowing down the recovery of the ozone layer, which protects life on Earth from harmful solar ultraviolet radiation.
Published Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide
(via sciencedaily.com) Original source Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.
