Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers      (via sciencedaily.com)     Original source 

Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.

Non-native species likely to continue spreading in North America, Australia and Europe      (via sciencedaily.com)     Original source 

Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.

Research provides crucial insights into moss growth under elevated CO2 levels that may benefit climate change models      (via sciencedaily.com)     Original source 

Approximately 12,000 species of mosses exist and cover close to four million square miles of earth, equivalent to the size of Canada, and are ecologically and evolutionarily important. Mosses play an essential role in rainwater retention, decreasing plant pathogens and increasing carbon sequestration in soil, thus improving the overall soil health. Mosses also protect long-term carbon storage systems, such as bogs and permafrost.

No scientific evidence for cognitively advanced behaviors and symbolism by Homo naledi      (via sciencedaily.com)     Original source 

A new study casts doubt on claims that Homo naledi, a small-brained hominin dating to between 335-241,000 years ago, deliberately buried their dead and produced rock art in Rising Star Cave, South Africa. Recent articles suggested the recent excavations at the Rising Star Cave system provided evidence of at least three burial features, two in the Dinaledi Chamber and a third in the Hill Antechamber cavity. The group of experts have now called for a deeper dig into the science behind the findings.

Naturally regrowing forests are helping to protect the remaining old forests in the Amazon      (via sciencedaily.com)     Original source 

Secondary forests that have regrown naturally on land abandoned from agriculture  are important in counteracting the effects of forest fragmentation across the Amazon basin, according to new findings.

Diverse forests hold huge carbon potential, as long as we cut emissions      (via sciencedaily.com)     Original source 

New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.

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.

New research exposes early humans' ecological versatility      (via sciencedaily.com)     Original source 

A recent study sheds new light on the ecological adaptability of early humans at the time when they first expanded their range outside Africa, 2--1 million years ago.

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.
