Scientists outline a bold solution to climate change, biodiversity loss, social injustice      (via sciencedaily.com)     Original source 

An international team of scientists has used a novel 500-year dataset to frame a 'restorative' pathway through which humanity can avoid the worst ecological and social outcomes of climate change.

Is natural spa water a fossil of water? Uncover the real ultra-deep water cycles      (via sciencedaily.com)     Original source 

Researchers have made a groundbreaking discovery regarding the origins of non-meteoric water in natural spa waters located in central Japan. Based on numerical modeling, their results suggest that this water has been confined within the lithosphere for an extensive period of 1.5-5 million years. They identified three primary sources for this ancient water: the Philippine Sea Plate, the Pacific Plate, and ancient seafloor sediments, particularly in the Niigata and southwest Gunma regions.

Spanish butterflies better at regulating their body temperature than their British cousins      (via sciencedaily.com)     Original source 

Butterfly populations in Catalonia in northern Spain are better than their UK counterparts at regulating their body temperature by basking in the sunshine, but rising global temperatures due to climate change may put Spanish butterflies at greater risk of extinction.

How did the bushpig cross the strait? A great puzzle in African mammal biogeography solved by genomics      (via sciencedaily.com)     Original source 

Africa has a huge diversity of large mammals, but their evolutionary relationships and movement across the continent over time often remain a mystery. A new scientific study sheds light on longstanding questions about the interplay between evolution and geography in one of these mammals, namely the iconic African bushpig, and helps settle a major question regarding prehistoric human activities shaping biodiversity patterns in Africa.

Global study of extreme drought impacts on grasslands and shrublands      (via sciencedaily.com)     Original source 

A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.

Widespread population collapse of African Raptors      (via sciencedaily.com)     Original source 

An international team of researchers has found that Africa's birds of prey are facing an extinction crisis. The report warns of declines among nearly 90% of 42 species examined, and suggests that more than two-thirds may qualify as globally threatened.

Evolution is not as random as previously thought      (via sciencedaily.com)     Original source 

A groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease and climate change. The study challenges the long-standing belief about the unpredictability of evolution, and has found that the evolutionary trajectory of a genome may be influenced by its evolutionary history, rather than determined by numerous factors and historical accidents.

Protected areas for elephants work best if they are connected      (via sciencedaily.com)     Original source 

The largest analysis yet of African savannah elephant populations shows that conservationists have successfully protected elephants in southern Africa for the last 25 years. However, the pattern varies regionally, with some elephant populations soaring and others still facing large declines. The key to long-term stability appears to be connecting large core areas with neighboring buffer zones, as opposed to well-protected but isolated protected areas known as 'fortress conservation.'

Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines      (via sciencedaily.com)     Original source 

Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.

Why are bees making less honey? Study reveals clues in five decades of data      (via sciencedaily.com)     Original source 

Honey yields in the U.S. have been declining since the 1990s, with honey producers and scientists unsure why, but a new study has uncovered clues in the mystery of the missing honey.

Seismic and infrasonic signals used to characterize Nord Stream pipeline events      (via sciencedaily.com)     Original source 

A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.

Microbial awakening restructures high-latitude food webs as permafrost thaws      (via sciencedaily.com)     Original source 

Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.

New reptile on the block: A new iguana species discovered in China      (via sciencedaily.com)     Original source 

Researchers have identified a new iguana species, Wang's garden lizard (Calotes wangi), in southern China and northern Vietnam. This species, part of the Calotes versicolor complex, was discovered through extensive surveys conducted from 2009 to 2022. Measuring less than 9 cm with an orange tongue, it inhabits subtropical and tropical forests, thriving in various landscapes including urban areas.

Tree plantations can get better with age -- but original habitats are best      (via sciencedaily.com)     Original source 

Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.

Common insect species are suffering the biggest losses      (via sciencedaily.com)     Original source 

Insect decline is being driven by losses among the locally more common species, according to a new study. The meta-analysis of 923 locations around the world notes two significant trends: 1) the species with the most individuals (the highest abundance) are disproportionately decreasing in number, and 2) no other species have increased to the high numbers previously seen. This likely explains the frequent observation that there are fewer insects around now than ten, twenty, or thirty years ago.

World's smallest 'fanged' frogs found in Indonesia      (via sciencedaily.com)     Original source 

Researchers have identified a species of frog new to science. The Indonesian amphibian is the size of a quarter, unlike its two-pound cousins, and has tiny fangs. Nearly uniquely among amphibians, they lay their eggs on the leaves of trees, and the males guard and tend to the nests.
