AI-driven plant root analysis      (via sciencedaily.com)     Original source 

As part of an investigation to boost agricultural yields and develop crops that are resilient to climate change, Berkeley Lab scientists have introduced RhizoNet, a computational tool that harnesses the power of AI to transform how we study plant roots and root behavior under various environmental conditions. A paper describing their innovative deep-learning approach, combined with a unique hydroponic device that facilitates in-situ plant imaging, was published June 5 in Scientific Reports.

Non-native plants and animals expanding ranges 100 times faster than native species      (via sciencedaily.com)     Original source 

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.

Restored rat-free islands could support hundreds of thousands more breeding seabirds      (via sciencedaily.com)     Original source 

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

Climate change: rising temperatures may impact groundwater quality      (via sciencedaily.com)     Original source 

As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.

Understanding the Green Sahara's collapse      (via sciencedaily.com)     Original source 

Abrupt shifts within complex systems such as the Earth's climate system are extremely hard to predict. Researchers have now succeeded in developing a new method to anticipate such tipping points in advance. They successfully tested the reliability of their method using one of the most severe abrupt climate changes of the past: the shift of the once-green Sahara into a desert.

Marine heatwaves devastate red gorgonians in the Medes Islands      (via sciencedaily.com)     Original source 

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.

New way to spot beetle-killed spruce can help forest, wildfire managers      (via sciencedaily.com)     Original source 

A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.

Scientists 'read' the messages in chemical clues left by coral reef inhabitants      (via sciencedaily.com)     Original source 

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.
