Vanishing glaciers threaten alpine biodiversity      (via sciencedaily.com)     Original source 

With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.

Indo-Pacific corals more resilient to climate change than Atlantic corals      (via sciencedaily.com)     Original source 

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.

Unraveling the mathematics behind wiggly worm knots      (via sciencedaily.com)     Original source 

Researchers wanted to understand precisely how blackworms execute tangling and ultrafast untangling movements for a myriad of biological functions. They researched the topology of the tangles. Their research could inform the design of fiber-like, shapeshifting robotics that self-assemble and move in ways that are fast and reversible.

Early-nesting ducks at increased risk due to changes in climate, land use      (via sciencedaily.com)     Original source 

Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.

How the Amazon rainforest is likely to cope with the effect of future drought      (via sciencedaily.com)     Original source 

A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.

A healthy but depleted herd: Predators decrease prey disease levels but also population size      (via sciencedaily.com)     Original source 

Nature documentaries will tell you that lions, cheetahs, wolves and other top predators target the weakest or slowest animals and that this culling benefits prey herds, whether it's antelope in Africa or elk in Wyoming. This idea has been widely accepted by biologists for many years and was formalized in 2003 as the healthy herds hypothesis. It proposes that predators can help prey populations by picking off the sick and injured and leaving healthy, strong animals to reproduce.

Woodpecker guides post-fire forest management      (via sciencedaily.com)     Original source 

What's good for the Black-backed Woodpecker is good for restoration of burned California forests. The birds' unique relationship with fire underpins the latest research into improved post-fire management. A study describes a new tool that factors in how fires burn into forest management decisions and turns science into action for wildlife conservation.

Creating a tsunami early warning system using artificial intelligence      (via sciencedaily.com)     Original source 

Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radiation produced by the earthquake, which carries information about the tectonic event and travels significantly faster than tsunami waves. The computational model triangulates the source of the earthquake and AI algorithms classify its slip type and magnitude. It then calculates important properties like effective length and width, uplift speed, and duration, which dictate the size of the tsunami.

Researchers use AI to discover new planet outside solar system      (via sciencedaily.com)     Original source 

A research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it. A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around newly formed stars. The newly published findings represent a first step toward using machine learning to identify previously overlooked exoplanets.

Biologists discover bees to be brew masters of the insect world      (via sciencedaily.com)     Original source 

Scientists have made a remarkable discovery about cellophane bees -- their microbiomes are some of the most fermentative known from the insect world. These bees, which are named for their use of cellophane-like materials to line their subterranean nests, are known for their fascinating behaviors and their important ecological roles as pollinators. Now, researchers have uncovered another aspect of their biology that makes them even more intriguing.

A new machine-learning system can generate protein designs with certain structural features, and which do not exist in nature. These proteins could be utilized to make materials that have similar mechanical properties to existing materials, like polymers, but which would have a much smaller carbon footprint.

Nature's chefs: Scientists propose food-making as means of understanding species interactions      (via sciencedaily.com)     Original source 

An interdisciplinary group of researchers is proposing a new way to think of some interactions between species, classifying a variety of plants, animals and fungi as 'nature's chefs.' Specifically, nature's chefs are organisms that provide food -- or the illusion of food -- to other organisms. The concept offers a new perspective on species interactions, which can inform how people think about food across the tree of life as well as disparate research disciplines.
