For mining in arid regions to be responsible, we must change how we think about water      (via sciencedaily.com)     Original source 

In an unprecedented study of the South American 'Lithium Triangle,' hydrologists discover that not all water responds the same way to environmental change and human use.

Early dinosaurs grew up fast, but they weren't the only ones      (via sciencedaily.com)     Original source 

The earliest dinosaurs had rapid growth rates, but so did many of the other animals living alongside them, according to a new study.

Groundbreaking research in groundwater's role in ecosystem sustainability      (via sciencedaily.com)     Original source 

Until now, groundwater -- a critical water resource around the globe, especially in dry regions -- has been largely unstudied in its importance and role in sustaining ecosystems. New groundbreaking research examines the relationship between groundwater and ecosystems across California.

Scientists' urgent call: End destruction and forge a just, sustainable future      (via sciencedaily.com)     Original source 

An international team of scientists published a study emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. The review summarizes the grave threats facing the planet but rejects a 'doom and gloom' philosophy. They advocate a global cultural shift that elevates kinship with nature and communal well-being, underpinned by the recognition of Earth's finite resources and the interconnectedness of its inhabitants.

These plants evolved in Florida millions of years ago: They may be gone in decades      (via sciencedaily.com)     Original source 

Scrub mints are among the most endangered plants you've probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level. In a new study, researchers show there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality.

Older trees help to protect an endangered species      (via sciencedaily.com)     Original source 

The oldest trees in the forest help to prevent the disappearance of endangered species in the natural environment, according to a new study. This is the case of the wolf lichen -- threatened throughout Europe --, which now finds refuge in the oldest trees in the high mountains of the Pyrenees. This study reveals for the first time the decisive role of the oldest trees in the conservation of other living beings thanks to their characteristic and unique physiology.

New method reveals hidden activity of life below ground      (via sciencedaily.com)     Original source 

Researchers have refined an innovative method for measuring the activity level of microbes and linking that to their individual genetic code, providing new insights into the microbial communities that thrive in extreme environments.

Computational tools fuel reconstruction of new and improved bird family tree      (via sciencedaily.com)     Original source 

Using cutting-edge computational methods and supercomputing infrastructure, researchers have built the largest and most detailed bird family tree to date -- an intricate chart delineating 93 million years of evolutionary relationships between 363 bird species, representing 92% of all bird families. The updated tree reveals sharp increases in effective population size, substitution rates and relative brain size in early birds in the aftermath of the mass extinction event that wiped out the dinosaurs 66 million years ago. And by closely examining one of the branches of this tree, researchers found that flamingos and doves are more distantly related than previous genome-wide analyses had shown.

Melting glaciers in a warmer climate provide new ground for invasive species      (via sciencedaily.com)     Original source 

In 2022 and 2023, biologists from research institutes in the UK and the Falkland Islands led two expeditions to South Georgia to study the impacts of invasive species on this cold and rugged sub-Antarctic island. They report that several invasive plants and invertebrates rapidly colonized the new ground exposed by melting glaciers, leaving few pristine areas for native species. With ongoing climate change, more research is needed across the world to understand how invasive species impact the fragile ecosystems that develop after glacier melting.

Canada lynx historic range in US likely wider than previously thought      (via sciencedaily.com)     Original source 

A broader past could mean a brighter future for Canada lynx in the U.S., according to recent research. The study indicates that lynx might do well in the future in parts of Utah, central Idaho and the Yellowstone National Park region, even considering climate change and the lack of lynx in those areas now. Using a model validated by historic records, researchers first found that in 1900, Canada lynx had more suitable habitat in the U.S. than the few northern corners of the country where they are found currently. The study showed the elusive big cat likely roamed over a larger area in the Pacific Northwest, Rocky Mountains, Great Lakes region and parts of New England.

Manganese plays a surprising role in soil carbon sequestration      (via sciencedaily.com)     Original source 

A recent study reveals an unexpected link between manganese -- a naturally occurring mineral -- and increased carbon emissions from high-latitude boreal forests. The study uncovers how manganese increases carbon emissions from boreal forest soil, over time, challenging conventional understanding of the role of manganese in the carbon cycle.

Going 'back to the future' to forecast the fate of a dead Florida coral reef      (via sciencedaily.com)     Original source 

How coral populations expand into new areas and sustain themselves over time is limited by the scope of modern observations. Going back thousands of years, a study provides geological insights into coral range expansions by reconstructing the composition of a Late Holocene-aged subfossil coral death assemblage in an unusual location in Southeast Florida and comparing it to modern reefs throughout the region. Findings offer a unique glimpse into what was once a vibrant coral reef assemblage and discover if history can repeat itself in the face of climate change.

Artificial reef designed by MIT engineers could protect marine life, reduce storm damage      (via sciencedaily.com)     Original source 

Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.

Scientists warn: The grey seal hunt is too large      (via sciencedaily.com)     Original source 

Researchers warn that today's hunting quotas of about 3,000 animals pose a risk to the long-term survival of the grey seal in the Baltic Sea. The conclusions of this new study are based on statistics from 20th century seal hunting and predictions of future climate change.
