Did rivers influence the evolution of Sumatran cascade frogs?
Is the geographical history of Sundaland closely linked to the evolution of the native Sumatran cascade frogs? This question was investigated by an international team led by herpetologist Umilaela Arifin of the LIB in their latest study, which was re.....»»
New research reveals terahertz waves" impact on dynamics of nanoconfined water molecules
In a new discovery, researchers have revealed novel insights into the behavior of water molecules confined within nanostructures. Their study, published in Science Advances on April 24, delves into how terahertz (THz) waves influence the dynamics of.....»»
Adaptation of photosynthetic mechanism in air plants occurs through gene duplication, study finds
Researchers at the University of Vienna, along with collaborators from France, Germany, Switzerland and the U.S., have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Till.....»»
Climate change reveals intricate dynamics of reproductive barriers in marine species
Monash University scientists have uncovered insights into how rising temperatures influence the reproductive interactions and species boundaries of marine organisms......»»
Better reservoir management could aid food security and fisheries conservation in US
After nearly a century of people building dams on most of the world's major rivers, artificial reservoirs now represent an immense freshwater footprint across the landscape. Yet, these reservoirs are understudied and overlooked for their fisheries pr.....»»
Aggressive wall lizard provides clues to understanding evolution
Body shape, color and behavior often evolve together as species adapt to their environment. Researchers from Lund University in Sweden have studied this phenomenon in a specific type of large, bright green and aggressive common wall lizard found near.....»»
Study provides new global accounting of Earth"s rivers
A study led by NASA researchers provides new estimates of how much water courses through Earth's rivers, the rates at which it's flowing into the ocean, and how much both of those figures have fluctuated over time—crucial information for understand.....»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Feds greenlight return of grizzly bears to Washington"s North Cascades
The National Parks Service and U.S. Fish & Wildlife Service filed a decision April 25 outlining a plan to capture three to seven grizzlies from other ecosystems in the Rocky Mountains or interior British Columbia and release them in the North Cascade.....»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
Managing meandering waterways in a changing world
Just as water moves through a river, rivers themselves move across the landscape. They carve valleys and canyons, create floodplains and deltas, and transport sediment from the uplands to the ocean......»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Study shows the longer spilled oil lingers in freshwater, the more persistent compounds it produces
Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year, there are many smaller-scale spills into lakes, rivers, and.....»»
Researcher finds that wood frogs evolved rapidly in response to road salts
When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research published in Ecology and Evolution a team led by Rick Relyea, Ph.D., professor of biological sciences and David M. Darrin Senior Endowed.....»»
Mantle heat may have boosted Earth"s crust 3 billion years ago
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare......»»
How evolution has optimized the magnetic sensor in birds
Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass. A team led by biologists Dr. Corinna Langebrake and Prof. Dr. Miriam Liedvogel from the University of Oldenburg and t.....»»
International study produces a comprehensive "tree of life" for flowering plants
With their own botanical collection material and their research knowledge on the evolution of cruciferous plants (plants of the cabbage family), bioscientists at Heidelberg University have contributed to a large-scale international study that has pro.....»»
Investigating the stereotypes pre-service teachers associate with pupils with special educational needs
In the course of inclusion, teachers are increasingly instructing pupils with special educational needs. Stereotypes regarding these children and adolescents can influence how the teachers deal with them. The DIPF | Leibniz Institute for Research and.....»»
A key gene helps explain how the ability to glide has emerged over-and-over during marsupial evolution
People say "When pigs fly" to describe the impossible. But even if most mammals are landlubbers, the ability to glide or fly has evolved again and again during mammalian evolution, in species ranging from bats to flying squirrels. How did that come a.....»»
Steelhead trout, once thriving in Southern California, are declared endangered
Southern California's rivers and creeks once teemed with large, silvery fish that arrived from the ocean and swam upstream to spawn. But today, these fish are seldom seen......»»
Fossil frogs share their skincare secrets: Analysis of 45-million-year-old soft tissues
Paleontologists at University College Cork (UCC), Ireland, have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts—it's all down to their skin......»»
