Study reveals new clues about how 'Earth's thermostat' controls climate      (via sciencedaily.com) 

Rocks, rain and carbon dioxide help control Earth's climate over thousands of years -- like a thermostat -- through a process called weathering. A new study may improve our understanding of how this thermostat responds as temperatures change.

Deer browsing is just one of many factors shaping North American forests      (via sciencedaily.com) 

In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.

New species of microalgae discovered      (via sciencedaily.com) 

A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers discovered Medakamo hakoo, whose DNA sequence didn't match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry.

Ancestral variation guides future environmental adaptations      (via sciencedaily.com) 

The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to -- this is known as phenotypic plasticity. New research shows that early plasticity can influence the ability to subsequently evolve genetic adaptations to conquer new habitats.

Rapid plant evolution may make coastal regions more susceptible to flooding and sea level rise, study shows      (via sciencedaily.com) 

Evolution has occurred more rapidly than previously thought in the Chesapeake Bay wetlands, which may decrease the chance that coastal marshes can withstand future sea level rise, researchers at the University of Notre Dame and collaborators demonstrated in a recent publication in Science.

How salmon feed flowers and flourishing ecosystems      (via sciencedaily.com) 

Nutrients from salmon carcasses can substantively alter the growth and reproduction of plant species in the surrounding habitat, and even cause some flowers to grow bigger and more plentiful, researchers have found.

Satellite data shows sustained severe drought in Europe      (via sciencedaily.com) 

Europe lacks groundwater -- a lot of groundwater. The continent has already been suffering from a severe drought since 2018. This is confirmed by satellite data.

Economics trump environment to save big cats, say ecologists      (via sciencedaily.com) 

Rapid economic growth has pushed rare species of big carnivores to the brink of extinction, but ecologists have suggested our appetite to once again live alongside big cats is increasing.

Immense diversity and interdependence in high temp deep-sea microorganism communities      (via sciencedaily.com) 

A new study finds that microorganisms live in richly diverse and interdependent communities in high-temperature geothermal environments in the deep sea. By constructing genomes of 3,635 Bacteria and Archaea from 40 different rock communities, researchers discovered at least 500 new genera and have evidence for two new phyla. Samples from the deep-sea Brothers volcano were especially enriched with different kinds of microorganisms, many endemic to the volcano. The genomic data from this study also showed that many of these organisms depend on one another for survival. Some microorganisms cannot metabolize all of the nutrients they need to survive so they rely on nutrients created by other species in a process known as a 'metabolic handoff.'

Asteroid findings from specks of space dust could save the planet      (via sciencedaily.com) 

New research into the durability and age of an ancient asteroid made of rocky rubble and dust, revealed significant findings that could contribute to potentially saving the planet if one ever hurtled toward Earth.

Can elephants save the planet?      (via sciencedaily.com) 

Researchers report that elephants play a key role in creating forests which store more atmospheric carbon and maintaining the biodiversity of forests in Africa. If the already critically endangered elephants become extinct, rainforest of central and west Africa, the second largest rainforest on earth, would lose between six and nine percent of their ability to capture atmospheric carbon, amplifying planetary warming.

New discovery: Endangered Amami rabbit disperses seeds for non-photosynthetic plant      (via sciencedaily.com) 

Seed dispersal is an essential process for the evolution and ecology of terrestrial plants, making discoveries of uncommon seed dispersal agents particularly interesting. Scientists now reveal that the Amami rabbit (Pentalagus furnessi) is a major seed dispersal agent for the non-photosynthetic plant Balanophora yuwanensis. To the best of our knowledge, this is the first known instance of rabbits serving as seed dispersal agents in Asia.

Unprecedented levels of high-severity fire burn in Sierra Nevada      (via sciencedaily.com) 

High-severity wildfire in California's Sierra Nevada forests has nearly quintupled compared to before Euro-American settlement, rising from less than 10% per year then to up to 43% today, a new study finds.

Forests face fierce threats from multiple industries, not just agricultural expansion      (via sciencedaily.com) 

Intact forests are important climate regulators and harbors of biodiversity, but they are rapidly disappearing. Agriculture is commonly considered to be the major culprit behind forest loss, but the authors of a new article show that agriculture isn't solely to blame. For forest loss associated with the 2014 world economy, over 60% was related to final consumption of non-agricultural products, such as minerals, metals and wood-related goods, and the authors argue that we must consider international trade markets when designing conservation strategies.

Researchers uncover secrets on how Alaska's Denali Fault formed      (via sciencedaily.com) 

New findings begin to fill major gaps in understanding about how geological faults behave and appear as they deepen, and they could eventually help lead future researchers to develop better earthquake models on strike-slip faults, regions with frequent and major earthquakes.
