The #Arctic is warming four times faster than the global average and #plant communities are responding through shifts in #species abundance, composition and distribution.

Species turnover was widespread, with 59% of plots gaining and/or losing species.

Proportions of species gains and losses were greater where temperatures had increased the most.

Arctic plant communities did not become more similar to each other, suggesting no biotic homogenization so far.

The Art of #DeExtinction: Reanimating #Species We’ve Lost

Save the Endangered Species Act https://act.biologicaldiversity.org/z0VvP2_CV0Cde__63LzWkg2?utm_source=Mastodon

Redefining the word “harm” to leave out habitat destruction, the biggest cause of #extinction, could be the nail in the coffin for imperiled species across the #UnitedStates and beyond, like Florida #manatees, green sea #turtles and spotted #owls. Speak up now, send a message to Acting Director Souza to protect #endangered #species and their #habitat — and the #EndangeredSpecies Act itself (via Center for Biological #Diversity ):

Imagine the #extinction of #experience - with #nature. But "Having the #language to name and describe nature is a gateway to curiosity-driven #innovation, #creativity and #discovery."

The colossal #squid was first described in 1925 based on specimens from the stomach of a commercially hunted sperm whale.

Now, an international voyage captured the first confirmed video of this #species in its natural habitat—a 30-centimeter juvenile, at a depth of 600 meters.

Colossal squid can grow up to 7 meters and weigh 500 kilograms, making them the heaviest invertebrate on the planet.

But little is known about their life cycle.

3-toed dinosaur footprint found in B.C. leads to discovery of new species
The dinosaur that made them is said to be between five and six metres long, spiky and armoured with a stiff tail or full club. The species has been named Ruopodosaurus clava.

Trump Administration Moves to Scrap Habitat Protections for All Threatened, Endangered Species https://biologicaldiversity.org/w/news/press-releases/trump-administration-moves-to-scrap-habitat-protections-for-all-threatened-endangered-species-2025-04-08/

Imo the only relevant #species definition for #deextintion is the ecological one. In other contexts this definition is absolutely silly, because it can't distinguish between a #bat and a #bird if they hunt #insects - it defines a species by their ecological #niche.

Under that definition, an elephant with hair is in fact a #mammoth because it's can live in tundra and serve as an umbrella species capable of shaping an entire #ecosystem, serving a unique role in it.

A #dire #wolf is not actually deextinct if it's not serving the ecosystem the way the OG dire wolf used to.

"The question is whether Colossal’s leaders and supporters are willing to pivot from a project that grabs news headlines to ones that would likely make positive differences. By tempting us with the resurrection of a long-dead creature, #Colossal forces us to ask: do we want conservation to be primarily about feeding an unreflective imagination? Or do we want evidence, logic, and ethics to be central to our relationships with other #species? For anyone who really cares about the #climate, #elephants, or #animals in general, #deextincting the #mammoth represents a huge waste and a colossal mistake."
