Global deforestation leads to more mercury pollution      (via sciencedaily.com)     Original source 

Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.

Scandinavia's first farmers slaughtered the hunter-gatherer population, study finds      (via sciencedaily.com)     Original source 

Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.

Friend or foe? Ancient partnership between moss and fungi      (via sciencedaily.com)     Original source 

Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.

Replacing animal-based foods with alternative proteins would unlock land for carbon removal      (via sciencedaily.com)     Original source 

Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.

Innovation in stone tool technology involved multiple stages at the time of modern human dispersals      (via sciencedaily.com)     Original source 

A new study illuminates the cultural evolution that took place approximately 50,000 to 40,000 years ago, coinciding with the dispersals of Homo sapiens across Eurasia. The insights gleaned from their examination of stone tool technology challenge the widely held notion of a rapid cultural and technological 'revolution' that enabled anatomically modern humans to surpass Neanderthals and other archaic humans. Instead, the research suggests a nuanced evolutionary process, unfolding gradually over an extended period, with changes occurring at various times. These findings challenge the conventional theory on the timing and nature of cultural transitions during this pivotal period in human history.

New study sheds new light on forests' role in climate and water cycle      (via sciencedaily.com)     Original source 

Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.

Complex tree canopies help forests recover from moderate-severity disturbances      (via sciencedaily.com)     Original source 

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.

Thailand's Iron Age Log Coffin culture      (via sciencedaily.com)     Original source 

A mortuary practice known as Log Coffin culture characterizes the Iron Age of highland Pang Mapha in northwestern Thailand. Between 2,300 and 1,000 years ago, individuals were buried in large wooden coffins on stilts, mostly found in caves and rock shelters.

How food availability could catalyze cultural transmission in wild orangutans      (via sciencedaily.com)     Original source 

The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?

Plant groupings in drylands support ecosystem resilience      (via sciencedaily.com)     Original source 

Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new article focused on the spatial patterns found in drylands offers important empirical evidence validating the models.

Scammed! Animals 'led by the nose' to leave plants alone      (via sciencedaily.com)     Original source 

Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.

Prehistoric mobility among Tibetan farmers, herders shaped highland settlement patterns, cultural interaction, study finds      (via sciencedaily.com)     Original source 

Using advanced geospatial modeling to compare environmental and archaeological evidence, researchers found evidence that connects ancient mobility and subsistence strategies to cultural connections forged among Tibetan farmers and herders in the Bronze and Iron Ages -- adding to understanding of how and why ancient communities built social relationships and cultural identities across the extreme terrain in Tibet.

Rare 3D fossils show that some early trees had forms unlike any you've ever seen      (via sciencedaily.com)     Original source 

In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.

Tidal landscapes a greater carbon sink than previously thought      (via sciencedaily.com)     Original source 

Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research shows that these environments are perhaps twice as effective as previously thought.

Increased temperature difference between day and night can affect all life on earth      (via sciencedaily.com)     Original source 

Researchers have discovered a change in what scientists already knew about global warming dynamics. It had been widely accepted since the 1950s that global temperature rises were not consistent throughout the day and night, with greater nighttime warming being observed. However, the recent study reveals a shift in dynamics: with greater daytime warming taking place since the 1990s. This shift means that the temperature difference between day and night is widening, potentially affecting all life on Earth.
