How do temperature extremes influence the distribution of species?      (via sciencedaily.com)     Original source 

As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.

Deep-sea mining and warming trigger stress in a midwater jellies      (via sciencedaily.com)     Original source 

The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

AI finds formula on how to predict monster waves      (via sciencedaily.com)     Original source 

Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs.

Deep dive on sea level rise: New modelling gives better predictions on Antarctic ice sheet melt      (via sciencedaily.com)     Original source 

Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise.   The Antarctic ice sheet is the largest block of ice on earth, containing over 30 million cubic kilometers of water.   Hence, its melting could have a devasting impact on future sea levels. To find out just how big that impact might be, the research team turned to the past.

Heat tolerant coral may trade fast growth for resilience      (via sciencedaily.com)     Original source 

Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. Researchers have now found that there was a tradeoff for corals dominated by the thermally sensitive algae -- they have higher growth, but only in cooler water.

New study reveals huge potential for future waves of invasive species      (via sciencedaily.com)     Original source 

Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.

Surveilling wetlands for infectious bird flu -- and finding it      (via sciencedaily.com)     Original source 

Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.
