Interaction with insects accelerates plant evolution      (via sciencedaily.com)     Original source 

Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.

When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change      (via sciencedaily.com)     Original source 

Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.

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.

AI shows how field crops develop      (via sciencedaily.com)     Original source 

Researchers developed software that can simulate the growth of field crops. To do this, they fed thousands of photos from field experiments into a learning algorithm. This enabled the algorithm to learn how to visualize the future development of cultivated plants based on a single initial image. Using the images created during this process, parameters such as leaf area or yield can be estimated accurately.

Can engineered plants help make baby formula as nutritious as breast milk?      (via sciencedaily.com)     Original source 

New research may help close the nutrition gap between infant formula and human breast milk. The study shows how plants can be programmed to produce a diverse array of beneficial sugars found in human breast milk. The findings could lead to healthier and more affordable formula for babies, or more nutritious non-dairy plant milk for adults.

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.

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.

Are plants intelligent? It depends on the definition      (via sciencedaily.com)     Original source 

Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?
