Scientists say sea-level changes formed Australia's K'Gari Sand Island, Great Barrier Reef      (via sciencedaily.com) 

Researchers report evidence the formation of K'gari and the Great Barrier Reef are linked to a change in the magnitude of sea-level rise and fall due to major climate feedback changes during the Middle Pleistocene Transition.

Half of replanted tropical trees don't survive      (via sciencedaily.com)     Original source 

On average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years, but there is enormous variation in outcomes, new research has found.

Putting the brakes on lithium-ion batteries to prevent fires      (via sciencedaily.com) 

Lithium-ion (Li-ion) batteries are used to power everything from smart watches to electric vehicles, thanks to the large amounts of energy they can store in small spaces. When overheated, however, they're prone to catching fire or even exploding. But recent research offers a possible solution with a new technology that can swiftly put the brakes on a Li-ion battery, shutting it down when it gets too hot.

Previously unseen processes reveal path to better rechargeable battery performance      (via sciencedaily.com) 

To design better rechargeable ion batteries, engineers and chemists have collaborated to combine a powerful new electron microscopy technique and data mining to visually pinpoint areas of chemical and physical alteration within ion batteries.

Study uncovers widespread and ongoing clearcutting of Swedish old forests      (via sciencedaily.com) 

Almost one fourth of Sweden's last unprotected old-growth forest was logged between 2003 and 2019. At this rate, all of these ecologically unique and valuable forests will be lost in about 50 years. These findings add to the growing body of evidence for widespread cryptic forest degradation across the global north.

Tropical cyclones act as 'massive heat pumps' that fuel extreme heat      (via sciencedaily.com) 

Extreme heat often follows tropical cyclones, which can complicate disaster recovery even further, researchers have found.

Sea urchins keep on trucking while other marine life languishes in the Florida Keys      (via sciencedaily.com) 

A litany of negative environmental pressures have had little to no effect on sand dollars and heart urchins in the Florida Keys, a new study shows. Scientists arrived at this unexpected conclusion after surveying 27 sites along a 20-mile stretch of coast near Long Key island. Five of the seven most common species known to inhabit the Florida Keys were present and accounted for in the survey and formed robust populations at varying depths.

The importance of light for grassland plant diversity      (via sciencedaily.com) 

Plants need light to grow. However, due to excess nutrients and/or the absence of herbivores less light can reach lower vegetation layers in grasslands. Consequently, few fast-growing species dominate and plant diversity declines. So far, this relationship has been established indirectly through experiments, but never directly by means of experimentally adding light in the field. Now biologists have been able to experimentally demonstrate the dominant role of light competition.

Invasive fruit fly may pose threat to forest ecosystems      (via sciencedaily.com) 

The invasive spotted wing drosophila (SWD) is a well-known pest in agriculture. A recent study by Swiss scientists now shows that the forest ecosystem is also affected by this alien insect. SWD infests the fruits of various forest plants and competes with other fruit-eating species. The decay of fruits attacked by SWD leads to a loss of resources, which can cause considerable ecological damage.

Antarctic summer thaw starts earlier, ends later than previously believed      (via sciencedaily.com) 

New research changes our understanding of seasonal thawing in parts of Antarctica, as scientists have learned that summer thawing occurs nearly a month earlier, and stays thawed for a full two months longer than previously believed.

Socio-economic factors shown to drive mangrove losses and gains      (via sciencedaily.com) 

New research into the drivers of mangrove loss over the past 20 years has revealed that most of the degradation can be attributed to socio-economic and biophysical factors, with mangrove cover increasing in some areas.

2D nanosheets as anodes in Li-ion batteries: The answer is in the sheets      (via sciencedaily.com) 

Researchers use titanium diboride nanosheets as anode material in lithium-ion batteries to enable fast charging and extend battery life.

Vegetation regulates energy exchange in the Arctic      (via sciencedaily.com) 

Global warming is changing the Arctic by causing permafrost thaw, glacier melt, droughts, fires and changes in vegetation. These developments are strongly linked to the energy exchange between land and the atmosphere. Researchers have now shown that different plant communities in the tundra play a key role in this energy exchange but are not taken into account in climate models.

Companies' 'deforestation-free' supply chain pledges have barely impacted forest clearance in the Amazon, researchers say      (via sciencedaily.com) 

More companies must make and implement zero-deforestation supply chain commitments in order to significantly reduce deforestation and protect diverse ecosystems, say researchers.

El Niño increases seedling mortality even in drought-tolerant forests      (via sciencedaily.com)     Original source 

Scientists conducted a 7-year study on seedling recruitment and mortality in a national park in Chiang Mai, in northern Thailand. During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found that seedling mortality increased in SDTFs when severe and prolonged drought occurred.

Batteries without critical raw materials      (via sciencedaily.com) 

The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. Researchers have investigated new combinations of electrolyte solutions and electrode materials for this purpose.

Plant processes may be key to predicting drought development      (via sciencedaily.com) 

Based on new analyses of satellite data, scientists have found that hydrologic conditions that increase flash drought risk occur more often than current models predict. The research also shows that incorporating how plants change soil structures can improve Earth system models.
