Published Climate change raised the odds of unprecedented wildfires in 2023-24 (via sciencedaily.com) Original source
Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts (via sciencedaily.com) Original source
A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
Published Expansion of agricultural land threatens climate and biodiversity (via sciencedaily.com) Original source
Food, feed, fiber, and bioenergy: The demand for agricultural raw materials is rising. How can additional cultivation areas be reconciled with nature conservation? Researchers have developed a land-use model that provides answers.
Published Forest restoration can boost people, nature and climate simultaneously (via sciencedaily.com) Original source
Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Published Mature forests vital in frontline fight against climate change (via sciencedaily.com) Original source
Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.
Published Millions of years for plants to recover from global warming (via sciencedaily.com) Original source
Catastrophic volcanic eruptions that warmed the planet millions of years ago shed new light on how plants evolve and regulate climate. Researchers reveal the long-term effects of disturbed natural ecosystems on climate in geological history and its implications for today.
Published Glossy black-cockatoos prefer the fruits of ancient rocks (via sciencedaily.com) Original source
New research has shown that glossy black-cockatoos prefer to feed from trees growing in acidic soils.
Published Nature at risk in the hunt for the perfect selfie (via sciencedaily.com) Original source
The need for a dramatic selfie or the perfect landscape photo is proving detrimental to nature, a new research collaboration has found.
Published Researchers make breakthrough in understanding species abundance (via sciencedaily.com) Original source
The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published Monitoring of nature reserves via social media and deep learning (via sciencedaily.com) Original source
Researchers have created a deep learning method to analyze social media images taken within protected green spaces to gain insights on human activity distribution as a way to monitor the ecological impacts of these activities.
Published Plants offer fruit to insects to disperse dust-like seeds (via sciencedaily.com) Original source
Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.
Published Elephants on the move: Mapping connections across African landscapes (via sciencedaily.com) Original source
Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
Published Living with a killer: How an unlikely mantis shrimp-clam association violates a biological principle (via sciencedaily.com) Original source
When clams gamble on living with a killer, sometimes their luck may run out, according to a new study.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description (via sciencedaily.com) Original source
A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.
Published A new way of thinking about the economy could help protect the Amazon, and help its people thrive (via sciencedaily.com) Original source
To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.
Published New research sheds light on relationships between plants and insects in forest ecosystems (via sciencedaily.com) Original source
Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species (via sciencedaily.com) Original source
A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Flamingos don't preen more than other waterbirds (via sciencedaily.com) Original source
Despite their famously fancy feathers, flamingos don't spent more time preening than other waterbirds, new research shows.
Published Warming stops tiny organisms working together (via sciencedaily.com) Original source
Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Mass extinction 66 million years ago triggered rapid evolution of bird genomes (via sciencedaily.com) Original source
Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.
