Published Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'
(via sciencedaily.com) Original source About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.
Published Arctic terns may navigate climate dangers
(via sciencedaily.com) Original source Arctic terns -- which fly on the longest migrations of any animal on Earth -- may be able to navigate the dangers posed by climate change, new research suggests.
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 Brown widow spiders: Invasive species prosper in favorable habitats and from a lack of local predators
(via sciencedaily.com) Original source Lower parasitism and predation in urban habitats may contribute to the invasion success of brown widow spiders, according to new research.
Published What can central Utah's earthquake 'swarms' reveal about the West's seismicity?
(via sciencedaily.com) Original source Much of central Utah's seismic activity comes in groups of small earthquakes. A study by seismologists examines 2,300 quakes occurring 40 'swarms' dating back to 1981, opening a window into Earth's crust in a geothermally active area.
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 Picturing where wildlands and people meet at a global scale
(via sciencedaily.com) Original source Researchers have created the first tool to map and visualize the areas where human settlements and nature meet on a global scale. The tool could improve responses to environmental conflicts like wildfires, the spread of zoonotic diseases and loss of ecosystem biodiversity.
Published Some corals may survive climate change without paying a metabolic price
(via sciencedaily.com) Original source If, as the saying goes, 'nothing in life is free,' then corals might pay a price for being resilient to climate change. Indeed, the prevailing belief among scientists has been that corals must suffer reduced growth or other tradeoffs when they partner with symbiotic algae that help them tolerate warmer water. Yet, new research demonstrates that certain corals can have their cake and eat it too, and as a result, these coral-symbiont partnerships may come to dominate reef ecosystems in a climate-changed future.
Published The legacy of past disturbance shapes coastal forest soil stability
(via sciencedaily.com) Original source Coastal forests are increasingly exposed to the effects of climate change and sea level rise. New experimental research examined how soils change when transplanted between parts of a tidal creek that differed in salinity. Scientists found that soils with a history of salinity and inundation by seawater were more resistant to changes in water conditions, suggesting that soils learn from their history of inundation.
Published How to track animal of legend? Look to the poop
(via sciencedaily.com) Original source Researchers applied genetic and isotopic analyses to jaguar scat to investigate the habitat needs of the big cats in the Mountain Pine Ridge Forest Preserve of Belize in Central America. The study demonstrates a novel and noninvasive technique for identifying the landscape use and conservation needs of elusive wildlife.
Published How do microbes spread globally? A study clarifies how they travel from end to end of the world
(via sciencedaily.com) Original source A new study compiles the scope of the problem of the global dispersal of harmful microorganisms through the upper layers of the atmosphere.
Published Into the unknown: NASA space laser provides answers to a rainforest canopy mystery
(via sciencedaily.com) Original source The space laser GEDI has allowed researchers to 3D map Earth's rainforests for the first time ever, helping us understand the forest canopy and providing vital information for understanding Earth's carbon cycle and how it is changing.
Published In Florida, endangered coral finds a way to blossom
(via sciencedaily.com) Original source In a new study, researchers have found that the restoration efforts of the critically endangered species elkhorn coral depend largely on the animal's location, microbiome, and the right conditions to provide an abundance of food.
Published Multiple uses of tropical mosaic landscapes
(via sciencedaily.com) Original source Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.
Published Small-winged and lighter colored butterflies likely to be at greatest threat from climate change
(via sciencedaily.com) Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.
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 Plastic pollution on coral reefs increases with depth and mostly comes from fishing activities
(via sciencedaily.com) Original source Researchers reveal the extent of plastic pollution on coral reefs, finding that debris increases with depth, largely stems from fishing activities, and is correlated with proximity to marine protected areas.
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 Conservation in Indonesia is at risk, a team of researchers who study the region argues
(via sciencedaily.com) Original source Indonesia, home to the largest tropical rainforest in Southeast Asia and over 17,500 islands, is a country packed with biodiversity and endangered species. However, scientists studying the region's species and ecosystems are getting banned from Indonesia, and conservation plans are being blocked. A team of conservation researchers with long-term experience in Indonesia discuss scientific suppression and other research challenges they have witnessed while working in the region. They offer suggestions for how to promote nature conservation, protect data transparency, and share research with the public in this and other regions of the world.
Published Arctic dust found to be a major source of particles that form ice crystals in Arctic low-level clouds
(via sciencedaily.com) Original source Scientists in Japan have used a global climate model to show that dust from land without snow cover in the Arctic is a major source of particles that form ice crystals in Arctic low-level clouds. This finding could help improve predictions of Arctic warming, which is suggested to be much faster than in other parts of the world.
