Just as the pandemic hit, Christina Islas Lynggaard—a postdoc researcher at the University of Copenhagen’s Globe Institute—sat in her apartment surrounded by vacuums and filters. She tested them, eventually landing on a water vacuum, which was, for her purposes, pretty good. The rest didn’t quite make the cut—they had good suction, but the second you put a filter in them, it messed with their power supplies. “It just dies, and then the motor comes to overheat, and it was very difficult,” Lynggaard said.

All this testing was done for an interesting case, one that seems obvious in hindsight but could have valuable ecological applications. In short, Lynggaard and other researchers on her team were looking for a way to collect environmental DNA (eDNA) from the air to measure biodiversity or look for the presence of rare or invasive species.

Out of thin air

“We had no idea the best way to collect DNA from air,” Kristine Bohmann told Ars. Bohmann is an associate professor at the Globe Institute and one of the researchers involved in the effort.

    The problem with blue carbon: can seagrass be replanted … by hand?

    news.movim.eu / TheGuardian · Friday, 5 November, 2021 - 07:00

The planet’s incredible marine carbon sink is vanishing – and the only way to replace it is costly, labour-intense and takes years. Experts say it’s worth it

Blue carbon: the hidden CO2 sink that pioneers say could save the planet

Inside a wooden boathouse on the shore of Loch Craignish, a mass of fronds sit in two 1,000-litre tanks. The fronds are seagrass, and they are filled with seeds. Next to the tanks is a Heath Robinson-style series of pumps. The laboratory may be low-tech, but it is the headquarters of a pioneering, community-led climate experiment.

The goal is to restore the loch’s once-thriving seagrass meadows. “We are trying to create a seismic change in the health of this sea loch,” says Danny Renton, of Craignish Restoration of Marine & Coastal Habitats (Cromach) and founder of Seawilding, a charity backed by people living in the surrounding villages in Argyll and Bute, about three hours’ drive from the Cop26 summit in Glasgow.

    How a mass extinction resulted in the rise of the snakes

The doom of the dinosaurs was good news for snakes. According to new research , snake biodiversity began increasing shortly after the Cretaceous–Paleogene mass extinction—you know, the one brought about by a huge asteroid impact 66 million years ago. The asteroid caused around 75 percent of all species, and all of the non-avian dinosaurs, to go extinct.

But the impact gave primordial snake species opportunity and space to flourish, and they did. Currently, there are around 4,000 species of the elongated, legless reptiles. To study this evolutionary change, a team of researchers examined the diets of existing snake species to get a glimpse into the past. “After the K–Pg extinction, [snakes] just underwent this massive ecological explosion,” Michael Grundler, one of the paper’s authors and a post-doc researcher at the University of California Los Angeles, told Ars.

Rare fossils

As it turns out, snake fossils are hard to come by. It’s rare to find any great snake because their bodies are loosely articulated and can fragment quickly. “They’re really rare in the fossil record. And when we do see them in the fossil record, it’s usually just a bit of vertebrae, often not really a skull, so we can’t get a sense of their ecology,” Grundler said. “It’s not something like a big mammal or a big dinosaur that has four limbs and the bones are pretty robust. With snakes, you have all these fragile vertebrae... their skull is pretty loosely articulated as well.”

    Transition vers un système educatif eco-solidaire

    David Sauvage · Monday, 20 September, 2021 - 12:46 · 2 minutes

Avec la Covid-19, la répercussion de la pandémie au niveau social est catastrophique, les familles subissent des pressions à tous les niveaux: l'isolement social, la peur de perdre son emploi, la diminution du salaire, l’augmentation du coût de la vie.

Le gouvernement a failli à sa mission d'éducation nationale en ne permettant pas aux enfants d’aller 5 jours par semaine à l'école, et cela a augmenté la pression dans les familles, qui doivent se démener pour assurer la garde des enfants, ou laisser les enfants à eux-mêmes devant la télévision.

Oui, il fallait réduire le nombre d'élèves par classe pour des raisons sanitaires, mais cela ne veut pas forcément dire que l’autre moitié doive rester à domicile. L'éducation doit se réinventer avec la Covid-19, et des activités périscolaires peuvent être organisées pour satisfaire les mesures sanitaires dans les classes.

Au lieu de relancer les cours par classe complète, le ministère de l'éducation devrait organiser des activités périscolaires pour la moitié de chaque classe un jour sur deux;

  • Activités sportives, dont initiations à la natation, aux sports en lien avec la nature
  • Initiations à l'écologie par la visite de nos trésors vivants (wetlands, dunes de sables, forêt, cave, rivière, lac, herbier marin, récif, îles et îlots)
  • Initiations aux activités artistiques (théâtre, musique, bricolage, danse, ...)
  • Initiations à l'agroécologie et à l’alimentation saine
  • Visites de nos musées et sites historiques

L’ensemble des travailleurs sociaux du secteur public, les associations dans l’éducation et le soin pourraient participer à cette transition de l'éducation nationale, pour compenser l’isolement des confinements et la violence de la crise sociale et économique qui s’installe déjà.

La Covid-19 est aussi la maladie de la biodiversité [1], au niveau macro avec la déforestation et l'élevage intensif qui provoque des zoonoses, mais aussi au niveau micro, avec l’appauvrissement de notre microbiome [2] facteur de maladies chroniques qui nous fragilise face à la Covid-19. Cela est en partie dûe à l’industrie de la malbouffe, qui ne favorise pas l’apport d’aliments sain et varié, et d’autre part aux pesticides & insecticides de l’agrobusiness et de la monoculture. C’est pourquoi fournir des repas bio et variés gratuits aux écoliers protégera nos jeunes de la pandémie et sera solidaire avec les classes sociales qui portent le fardeau de la pandémie.

Venez construire avec nous la transition vers une économie écologique et solidaire, qui nous mènera vers une santé planétaire.

    How to protect species and save the planet—at the same time

How to protect species and save the planet—at the same time

Humanity is struggling to contain two compounding crises: skyrocketing global temperatures and plummeting biodiversity. But people tend to tackle each problem on its own, for instance by deploying green energies and carbon-eating machines while roping off ecosystems to preserve them. But in a new report, 50 scientists from around the world argue that treating each crisis in isolation means missing out on two-fer solutions that resolve both. Humanity can't solve one without also solving the other.

The report is the product of a four-day virtual workshop attended by researchers of all stripes and is a collaboration between the United Nations’ Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services and the Intergovernmental Panel on Climate Change. In light of the Paris Agreement , it’s meant to provide guidance on how campaigns that address biodiversity might also address climate change, and vice versa.

The plain-language report should prove to be hugely influential not only among governmental policymakers and conservation groups, but also among corporations, says Betsy Beymer-Farris, a sustainability scientist at the University of Kentucky, who wasn’t involved in the report but did peer review it. “It's hard for companies or even nation states to really distill academic literature,” Beymer-Farris says. The report both lays out the climate and biodiversity science and the social science of how to effect change with the help of the people who actually rely on the land for farming and grazing. “I definitely got excited when I reviewed the report,” Beymer-Farris adds. “I thought: OK, this is definitely different from what I've seen before because it's a conscious and serious engagement with a more equitable and just way forward.”

    Indigenous forest gardens remain productive and diverse for over a century

In the 1930s, an archeologist from the Smithsonian wrote a short paper remarking on the exquisite vegetation around First Nation villages in Alaska. The surroundings were filled with nuts, stone fruit, berries, and herbs—several non-native to the area and many that would never grow together naturally. Apart from this brief mention, however, the significance of these forest gardens went largely overlooked and unrecognized by modern archeology for the next 50-plus years.

In the last decades, archeologists have learned that perennial forest management—the creation and care of long-lived food-bearing shrubs and plants next to forests—was common among the Indigenous societies of North America’s northwestern coast. These forest gardens played a central role in the diet and stability of these cultures in the past, and now a new publication shows that they offer an example of a far more sustainable and biodiverse alternative to conventional agriculture.

In a collaboration with the Tsm’syen and Coast Salish First Nations, this research shows that these gardens have become lasting hotspots of biodiversity, even 150 years after colonists forcibly removed the inhabitants from their villages. In a project combining archeology, botany, and ecology, this work is the first to systematically study the long-term ecological effects of Indigenous peoples’ land use in this region. Beyond the impressive longevity of these gardens, they offer ideas for farming practices that might restore, rather than deplete, local resources to create healthier, more resilient ecosystems.

    Average westerner's eating habits lead to loss of four trees every year

    news.movim.eu / TheGuardian · Monday, 29 March, 2021 - 15:00

Research links consumption of foods such as coffee and chocolate to global deforestation

The average western consumer of coffee, chocolate, beef, palm oil and other commodities is responsible for the felling of four trees every year, many in wildlife-rich tropical forests, research has calculated.

Destruction of forests is a major cause of both the climate crisis and plunging wildlife populations, as natural ecosystems are razed for farming. The study is the first to fully link high-resolution maps of global deforestation to the wide range of commodities imported by each country across the world.
