Published New research reveals the impact of different species and their traits on human wellbeing
(via sciencedaily.com) Original source New research has revealed that well-functioning ecosystems are crucial to human health and wellbeing, with human-biodiversity interactions delivering wellbeing gains equating to substantial healthcare cost-savings, when scaled-up across populations.
Published Supersized fruit eater database on climate change frontline
(via sciencedaily.com) Original source To conserve precious and fragile biodiversity hotspots, a crucial step is knowing how the fruit eaters are doing. To assist in that, scientists and students have supersized a database to keep track of such animals and birds.
Published Completing genome of rusty patched bumble bee may offer new approach to saving endangered bee
(via sciencedaily.com) Original source A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.
Published Cryo conservation: A cool solution to saving species from extinction
(via sciencedaily.com) Original source In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.
Published New dinosaur discovered: Ankylosaurs may have been far more diverse than originally thought
(via sciencedaily.com) Original source First armoured dinosaur to be described from the Isle of Wight in 142 years, shows Ankylosaurs may have been far more diverse than originally thought
Published How fungus farming ants keep their gardens healthy
(via sciencedaily.com) Original source 'Weed early and often' is the key to a productive garden. Interestingly, certain species of ants are also avid gardeners, a practice they've refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report how ants distinguish the good fungus from the bad.
Published How will a warming world impact the Earth's ability to offset our carbon emissions?
(via sciencedaily.com) Original source New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
Published This salty gel could harvest water from desert air
(via sciencedaily.com) Original source Engineers synthesized a superabsorbent material that can soak up a record amount of moisture from the air, even in desert-like conditions.
Published 10-year countdown to sea-ice-free Arctic
(via sciencedaily.com) Original source Research team predicts Arctic without ice by the end of 2030s if current increasing rate of greenhouse gas emission continues.
Published Scientists discover urea in atmosphere revealing profound consequences for climate
(via sciencedaily.com) Original source Areas of the ocean that are rich in marine life are having a bigger impact on our ecosystems and the climate than previously thought, new research suggests.
Published The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark
(via sciencedaily.com) Original source A survey of groundwater samples drawn from aquifers beneath more than 80,000 square miles of Canadian prairie reveals ancient groundwaters harbor not only diverse and active microbial communities, but also unexpectedly large numbers of microbial cells. Strikingly, some of these microbes seem to produce 'dark oxygen' (in the absence of sunlight) in such abundance that the oxygen may nourish not only those microbes, but may leak into the environment and support other oxygen-reliant microbes that can't produce it themselves.
Published Newly planted vegetation accelerates dune erosion during extreme storms, research shows
(via sciencedaily.com) Original source Newly planted vegetation on coastal sand dunes can accelerate erosion from extreme waves.
Published Preserving forests to protect deep soil from warming
(via sciencedaily.com) Original source An innovative, decade-long experiment in the foothills of California's Sierra Nevada mountains shows carbon stocks buried deep underground are vulnerable to climate change. The findings have implications for mitigating global warming through the natural carbon sinks provided by soil and forests which capture 25% of all carbon emissions.
Published Hotter sand from microplastics could affect sea turtle development
(via sciencedaily.com) Original source New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.
Published Skipping evolution: Some kangaroos didn't hop
(via sciencedaily.com) Original source Extinct kangaroos used alternative methods to their famous hop according to comprehensive analysis.
Published Plant remediation effects on petroleum contamination
(via sciencedaily.com) Original source Initial choices about fertilization and grass seeding could have a long-lasting effect on how plants and their associated microbes break down pollution in petroleum-contaminated soils.
Published Ancient herbivore's diet weakened teeth leading to eventual starvation, study suggests
(via sciencedaily.com) Original source Researchers have shed light on the life of the ancient reptile Rhynchosaur, which walked the earth between 250-225 million years ago, before being replaced by the dinosaurs.
Published Eddies: Circular currents and their influence on the world's hottest ocean
(via sciencedaily.com) Original source Water from the Pacific Ocean flows into the Indian Ocean via the Indonesia Archipelago thanks to a vast network of currents that act as a conveyor belt, transporting warmth and nutrients. Currents can sometimes form circular motions and these are known as eddies. An international group of researchers has modeled the impacts of eddies on the currents that carry water from the Pacific Ocean to the Indian Ocean.
Published MethaneMapper is poised to solve the problem of underreported methane emissions
(via sciencedaily.com) Original source MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.
Published Lost giants: New study reveals the abundance decline of African megafauna
(via sciencedaily.com) Original source A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.
