Pause in recent coral recovery on much of Great Barrier Reef      (via sciencedaily.com) 

In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.

AI transformation of medicine: Why doctors are not prepared      (via sciencedaily.com) 

The success of artificial intelligence technologies depends largely on how physicians interpret and act upon a tool's risk predictions -- and that requires a unique set of skills that many are currently lacking, according to a new perspective article.

In the treetops: Ecologist studies canopy soil abundance, chemistry      (via sciencedaily.com)     Original source 

Ecologists examined the distribution patterns of canopy soils, and their soil properties, across Costa Rican forests. The researchers suggest canopy soil may store more carbon than previously thought. Consideration of the time needed for reforestation of system with tree canopies should include the time needed for canopy mat regrowth.

How good is that AI-penned radiology report?      (via sciencedaily.com) 

New study identifies concerning gaps between how human radiologists score the accuracy of AI-generated radiology reports and how automated systems score them. Researchers designed two novel scoring systems that outperform current automated systems that evaluate the accuracy of AI narrative reports. Reliable scoring systems that accurately gauge the performance of AI models are critical for ensuring that AI continues to improve and that clinicians can trust them.

Scientists dig into wildfire predictions, long-term impacts      (via sciencedaily.com)     Original source 

Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.

Study analyzes nearshore California marine heatwaves and cold spells amid changing climate conditions      (via sciencedaily.com)     Original source 

Human-caused climate change has also caused extreme ocean temperatures and conditions with detrimental impacts on marine ecosystems and ocean-related ecology.  A new study explores ocean temperature data along California's Coast, finding that certain environmental conditions and the state of the ocean led to an enhanced risk for marine heatwaves and cold spells, conditions that scientists and environmental managers will need to monitor to preserve and protect vital ecosystems critical to the California ocean economy, known as the Blue Economy.

Researchers find evolutionary adaption in trout of Wyoming's Wind River Mountains      (via sciencedaily.com)     Original source 

Scientists found that trout from lakes stocked decades ago in the Wind River Mountains have higher numbers of gill rakers, which are bony or cartilage structures in the gullets of fish that act as sieves to retain zooplankton and nourish the trout. The difference is likely a result of the trout adapting to the food sources of the once-fishless high-mountain lakes -- a change that has taken place in a relatively short period of time and at a rate that is generally consistent with the historic timing of stocking for each of the lakes.

Breakthrough in Monte Carlo computer simulations      (via sciencedaily.com) 

Researchers have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with their neighbors but also far beyond.

Global wildlife trade risks altering evolutionary history and ecosystem function, study suggests      (via sciencedaily.com)     Original source 

Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.

Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'      (via sciencedaily.com)     Original source 

About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.

An inverse model for food webs and ecosystem stability      (via sciencedaily.com)     Original source 

Researchers invert a classical approach to modeling food webs. Instead of trying to replicate stable, complex ecosystems using simplistic representations of species interactions, the authors' novel inverse method assumes the ecosystems exist and works backward to characterize food webs that support that assumption. Their work represents a significant step toward addressing a fundamental ecological question of how biodiversity promotes ecosystem stability. The findings offer insights into how nature may respond to growing anthropogenic disturbances.

Research supports use of managed and prescribed fires to reduce fire severity      (via sciencedaily.com)     Original source 

Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.

Road salt pollution in many US lakes could stabilize at or below thresholds set by the EPA      (via sciencedaily.com)     Original source 

For lakes in areas with light to moderate road density, the authors found that holding road salt application rates steady could help lakes stabilize below 230 mg/l of chloride per liter of water, the threshold designated by the EPA to protect aquatic life. Reducing application could yield additional environmental and economic benefits without threatening road safety.

Climate scientist finds new way to measure the Earth's ability to offset carbon emissions      (via sciencedaily.com)     Original source 

Scientists have determined how the Earth responds as it heats up due to climate change. Their study is the first to find the temperature-carbon dioxide release relationship at the landscape level. Plants that currently take up a quarter to a third of humanity's carbon emissions might not be able to maintain the rate of carbon dioxide removal.

Picturing where wildlands and people meet at a global scale      (via sciencedaily.com)     Original source 

Researchers have created the first tool to map and visualize the areas where human settlements and nature meet on a global scale. The tool could improve responses to environmental conflicts like wildfires, the spread of zoonotic diseases and loss of ecosystem biodiversity.

Understanding the many different ways animals are evolving in response to fire could help conservation efforts      (via sciencedaily.com)     Original source 

In our modern era of larger, more destructive, and longer-lasting fires -- called the Pyrocene -- plants and animals are evolving quickly to survive. By synthesizing the wide body of research about rapid animal evolution in response to fire, a multidisciplinary team of ecology experts hopes to leverage what we already know to help foster evolution-informed conservation plans. In this way, they suggest, we can try to harness the ways in which fire impacts animals to protect vulnerable species -- working with evolution instead of against it.
