Published Retreating glaciers: Fungi enhance carbon storage in young Arctic soils
(via sciencedaily.com) Original source Melting Arctic glaciers are in rapid recession, and microscopic pioneers colonize the new exposed landscapes. Researchers revealed that yeasts play an important role in soil formation in the Arctic.
Published Researchers develop predictive model for cross-border COVID spread
(via sciencedaily.com) Original source Post-COVID research has extensively focused on the efficacy of internal travel restrictions and cross-border travel has received less attention due to challenges in accessing quality data. In a major multidisciplinary collaboration effort across Finland, Sweden, Norway, and Denmark, a group of researchers -- including mathematicians, physicists and computer scientists -- have published a pioneering study on the spread of infections across Nordic borders from spring until the end of 2020. The report sheds light on the efficacy of cross-border travel restrictions, helping us better understand which measures actually make a difference.
Published Climate change drives tree species towards colder, wetter regions
(via sciencedaily.com) Original source Climate change is likely to drive tree species towards colder and wetter regions.
Published Ocean acidification turns fish off coral reefs
(via sciencedaily.com) Original source A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species.
Published AI-powered study explores under-studied female evolution
(via sciencedaily.com) Original source Pioneering AI-powered research on butterflies has probed the under-studied evolution of females and adds to a debate between Charles Darwin and Alfred Russel Wallace.
Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters
(via sciencedaily.com) Original source A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Published The evidence is mounting: humans were responsible for the extinction of large mammals
(via sciencedaily.com) Original source Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Published Choose where to plant energy crops wisely to minimise loss of biodiversity
(via sciencedaily.com) Original source In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Ecologists reconstruct the history of biodiversity in the Indo-Australian archipelago and its rise as a hotspot
(via sciencedaily.com) Original source The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.
Published Climate change to shift tropical rains northward
(via sciencedaily.com) Original source Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.
Published Projected loss of brown macroalgae and seagrasses with global environmental change
(via sciencedaily.com) Original source Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs
(via sciencedaily.com) Original source Ammonites were not in decline before their extinction, scientists have found.
Published Invasive ants spread by hitchhiking on everyday vehicles
(via sciencedaily.com) Original source Ants might spread to new locations by stowing away on everyday vehicles. Previously, this was thought to occur mostly on agricultural equipment.
Published Why the harsh Snowball Earth kick-started our earliest multicellular ancestors
(via sciencedaily.com) Original source Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again?
(via sciencedaily.com) Original source Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published Plankton researchers urge their colleagues to mix it up
(via sciencedaily.com) Original source A new article encourages researchers to focus their attention on mixoplankton, providing a set of methodologies to help expand our understanding of this critically important component of the marine ecosystem.
Published Frog 'saunas' a lifeline for endangered frog populations
(via sciencedaily.com) Original source New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published Non-stop flight: 4,200 km transatlantic flight of the Painted Lady butterfly mapped
(via sciencedaily.com) Original source In October 2013 a researcher made a surprising discovery of Painted Lady Butterflies on the Atlantic beaches of French Guiana -- a species not typically found in South America. This unusual sighting prompted an international study to investigate the origin of these butterflies.
Published Fuel treatments reduce future wildfire severity
(via sciencedaily.com) Original source There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.
