Heat, cold extremes hold untapped potential for solar and wind energy      (via sciencedaily.com)     Original source 

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.

Researchers find energy development and tree encroachment impact Wyoming pronghorn      (via sciencedaily.com)     Original source 

While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.

Seeing the forest for the trees: Species diversity is directly correlated with productivity in eastern U.S. forests      (via sciencedaily.com)     Original source 

When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.

Species diversity promotes ecosystem stability      (via sciencedaily.com)     Original source 

What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? A new study suggests an answer to this question that has been a subject of debate among ecologists for half a century.

Forest, stream habitats keep energy exchanges in balance, global team finds      (via sciencedaily.com)     Original source 

Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.

Scientists weigh up current status of blue whale populations around the world      (via sciencedaily.com)     Original source 

The largest living animal, the blue whale (Balaenoptera musculus) which averages about 27 meters in length, has slowly recovered from whaling only to face the rising challenges of global warming, pollution, disrupted food sources, shipping, and other human threats. In a major new study, biologists have taken a stock of the number, distribution and genetic characteristics of blue whale populations around the world and found the greatest differences among the eastern Pacific, Antarctic subspecies and pygmy subspecies of the eastern Indian and western Pacific.

Researchers sought to understand how diatoms -- microscopic, photosynthetic algae that make up an estimated 20 percent of global carbon sequestration and oxygen production -- are able to bloom in an ice-covered Lake Erie and how ice decline across the Great Lakes is impacting the algae.

Artificial streams reveal how drought shapes California's alpine ecosystems      (via sciencedaily.com)     Original source 

Researchers have used a series of artificial stream channels to mimic the behavior of headwater creeks under future climate change scenarios. They found that drier conditions shifted the life cycles of the algae and insects that form the base of the alpine food web. However, because species adjusted to the shifts in a variety of ways, the stream ecosystems were generally resilient to the changing conditions.

Harnessing hydrogen at life's origin      (via sciencedaily.com)     Original source 

A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.

Why do tree frogs lay their eggs on the ground?      (via sciencedaily.com)     Original source 

A curious aspect of tree frogs is that they often lay their eggs on the ground where the risk of predation by natural enemies is greater than in the trees where they live. A research team suggested that the reason for this behavior is to protect the eggs from low temperatures. Their findings highlight the challenge faced by tree frogs: Should they attempt to maintain an optimal temperature for their eggs or risk predation?
