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.

One of my biggest pet peeves ever is seeing people going out of their ways to make cool-looking scientific specimens for an imaginary (or real) species and then capitalizing the specific epithet. Please do this: "Tyrannosaurus rex" and not this: "Tyrannosaurus Rex". And also set the scientific name in italics, wherever that's possible :)

To survive as a #species, aquatic organisms have developed fascinating strategies. However, there are limits to the #resilience of organisms, especially when changes occur at a high rate. This has been shown by researchers at IGB https://www.igb-berlin.de/en/news/resilient-yet-vulnerable

“High #phylogenetic distance between non-native #species and the recipient community increases #invasion success.”

- the formal definition #invasion #scientists propose in structured format for #Darwin’s #naturalisation hypothesis.

Might do a #commission special this month: answer three questions and get a #CosmicDash #OC based on your answers for $10.

Either any of the #species or I may limit it to the Floraran, as they are plant aliens and it works for April.

It’s a funny time for “abundance” to be on the agenda when literally the first source of any kind of abundance - species abundance - is rapidly declining across all #species & #ecosystems.

Of course, this is not part of Klein/Thompson’s analysis.

we are living through an #ExtinctionCrisis unlike anything in human history—over a million #species are at risk of disappearing in the coming decades. #ecosystems that have taken millions of years to evolve are unravelling before our eyes, driven by #HabitatDestruction, #climate chaos, #pollution, and endless #extraction. every species lost is a thread pulled from the web of life, and sooner or later, that web collapses. ⁠

Dear culture-shock-video-maker, if you were to lonely witness a landing of an extra-terrestrial #spaceship

Standing all alone in the nowhere and you would be conscious that you must react now somehow.

However, already the landing flap of this spaceship opens, some smoke rises, a billowing #species approaches,

... two, three tentacles reach for you and slowly driving up into your nostrils... (1/2)

when #ecosystems thrive, they protect us—absorbing #floods, softening #heatwaves, keeping #disease in check. #forests, #wetlands, #reefs, and #grasslands act as nature’s safety net, holding everything in #balance. but when we destroy them, we unravel the very systems keeping us alive. ⁠
⁠
by protecting #nature, we protect ourselves. every #tree, every #river, every #species is part of the web that holds our world together. if we want a future, we have to fight for it.
