Bacteria-virus arms race provides rare window into rapid and complex evolution      (via sciencedaily.com)     Original source 

Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria and viruses, researchers are documenting rapid evolutionary processes in simple laboratory flasks in only three weeks.

Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken      (via sciencedaily.com)     Original source 

Experts predict 'catastrophic ecosystem collapse' of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.

Maps reveal biochar's potential for mitigating climate change      (via sciencedaily.com)     Original source 

Twelve countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%.

Cracking the code: Genome sequencing reveals why songbirds are larger in colder climates      (via sciencedaily.com)     Original source 

Scientists have unlocked the genetic basis underlying the remarkable variation in body size observed in song sparrows, one of North America's most familiar and beloved songbirds. This discovery also provides insights into this species' capacity to adapt to the challenges of climate change. The study used genomic sequencing to successfully pinpoint eight genetic variants, or DNA mutations, largely responsible for the nearly threefold difference in body size observed across the song sparrow range from Mexico to Alaska.

A database unifies the information on damage to European forests over the last 60 years      (via sciencedaily.com)     Original source 

Researchers are creating a database that harmonizes the recording of disturbances caused by insects and diseases in forests in 8 European countries by combining remote sensing, satellite images and field data.

The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal      (via sciencedaily.com)     Original source 

Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.

New algae species rewrites understanding of reef systems      (via sciencedaily.com)     Original source 

An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.

Fossils tell tale of last primate to inhabit North America before humans      (via sciencedaily.com)     Original source 

Paleontologists have shed light on the long-standing saga of Ekgmowechashala, based on fossil teeth and jaws found in both Nebraska and China. Ekgmowechashala is the last primate found in the fossil record before humans.

Crust-forming algae are displacing corals in tropical waters worldwide      (via sciencedaily.com)     Original source 

Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.

Large herbivores such as elephants, bison and moose contribute to tree diversity      (via sciencedaily.com)     Original source 

Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.

To restore ecosystems, think about thwarting hungry herbivores      (via sciencedaily.com)     Original source 

Re-establishing plantings of trees, grasses and other vegetation is essential for restoring degraded ecosystems, but a new survey of almost 2,600 restoration projects from nearly every type of ecosystem on Earth finds that most projects fail to recognize and control one of the new plants' chief threats: hungry critters that eat plants.
