Ancient DNA reveals the appearance of a 6th century Chinese emperor      (via sciencedaily.com)     Original source 

What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study suggests the emperor's death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.

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.

Uncovering the mystery of Dorset's Cerne Giant      (via sciencedaily.com)     Original source 

For centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.

Persian plateau unveiled as crucial hub for early human migration out of Africa      (via sciencedaily.com)     Original source 

A new study combining genetic, palaeoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa. It highlights the period between 70,000 to 45,000 years ago when human populations did not uniformly spread across Eurasia, leaving a gap in our understanding of their whereabouts during this time frame.

Scientists uncover evidence that microplastics are contaminating archaeological remains      (via sciencedaily.com)     Original source 

A team of archaeologists discovered tiny microplastic particles in deposits located more than seven meters deep, in samples dating back to the first or early second century and excavated in the late 1980s.

Tudor era horse cemetery in Westminster revealed as likely resting place for elite imported animals      (via sciencedaily.com)     Original source 

Archaeological analysis of a near unique animal cemetery discovered in London nearly 30 years ago has revealed there was an international horse trading network, orchestrated by the elites of late medieval and Tudor England, which brought superior physical specimens to the UK for jousting and for use as status symbols.

Researchers name prehistoric amphibian ancestor discovered in Smithsonian collection after Kermit the Frog      (via sciencedaily.com)     Original source 

Scientists have uncovered the fossilized skull of a 270-million-year-old ancient amphibian ancestor in the collection of the Smithsonian's National Museum of Natural History. The team of researchers described the fossil as a new species of proto-amphibian, which they named Kermitops gratus in honor of the iconic Muppet, Kermit the Frog.

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.

Study reveals 'cozy domesticity' of prehistoric stilt-house dwellers in England's ancient marshland      (via sciencedaily.com)     Original source 

Detailed reports on thousands of artifacts pulled from 'Britain's Pompeii' reveals the surprisingly sophisticated domestic lives of Bronze Age Fen folk some 3,000 years ago -- from home interiors to recipes, clothing, kitchenware and pets.

Researchers investigate how freshwater diatoms stay in the light      (via sciencedaily.com)     Original source 

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.

New archive of ancient human brains challenges misconceptions of soft tissue preservation      (via sciencedaily.com)     Original source 

A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.

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.

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?
