Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction      (via sciencedaily.com)     Original source 

A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.

Buried ancient Roman glass formed substance with modern applications      (via sciencedaily.com)     Original source 

Researchers discover how molecules in ancient glass rearrange and recombine with minerals over centuries to form a patina of photonic crystals -- ordered arrangements of atoms that filter and reflect light in very specific ways -- an analog of materials used in communications, lasers and solar cells.

Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration      (via sciencedaily.com) 

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.

Rivers are rapidly warming, losing oxygen; aquatic life at risk      (via sciencedaily.com)     Original source 

Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.

How just one set of animal tracks can provide a wealth of information      (via sciencedaily.com)     Original source 

Rock faces in Namibia are decorated with hundreds of stone-age images not only of animals and human footprints, but also of animal tracks. These have been largely neglected to date as researchers lacked the knowledge required to interpret them. Archaeologists have now worked together with animal tracking experts to investigate the engraved animal tracks on six rock faces in more detail, and were able to determine detailed information on the species, age, sex, limbs, side of the body, trackway and relative direction of the tracks.

Shipboard cannon found off the Swedish coast may be the oldest in Europe      (via sciencedaily.com)     Original source 

Maritime archaeologists have studied what might be Europe's oldest shipboard cannon. The cannon was found in the sea off Marstrand on the Swedish west coast and dates back to the 14th century. The findings from the interdisciplinary study contribute new knowledge about the early development of artillery on land and at sea, but also bears witness to a troubled period for seafarers as well as coastal populations.

Protected nature reserves alone are insufficient for reversing biodiversity loss      (via sciencedaily.com)     Original source 

Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.

Some spiders can transfer mercury contamination to land animals      (via sciencedaily.com) 

Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.

Freshwater connectivity can transport environmental DNA through the landscape      (via sciencedaily.com) 

A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
