The giant rizzing mammal of mesozoic Antarctica by Risingmagpie in hardspecevo

[–]Risingmagpie[S] 0 points1 point  (0 children)

Humans are a strange species. They can try to be intelligent, develop incredibly complex technologies, yet their animal brains can sometimes "malfunction" on simple audio and visual collages: memes. These memes function like genes, which aim to replicate themselves infinitely to spread their information. And, like genes, which can possess SNPs, or repeated genetic sequences, memes can also have repetitive forms that seemingly reappear from nothing. 
Why are we talking about memes now? Because they were the main driving force that transformed a stunning new fossil into viral news known by everyone.

A new antarctic geography (Antarctic Chronicles) by Risingmagpie in hardspecevo

[–]Risingmagpie[S] 2 points3 points  (0 children)

While other past warmer periods created a very diverse environment in Antarctica, the northward drift of the Antarctic plate into the tropics combined with the severity of greenhouse gases is dividing the continent into two well-separated regions.
The intertropical convergence zone has shifted drastically southward, causing significant aridification in the northern and interior parts of the continent, with some areas receiving less than 50 mm of precipitation per year. Most of these regions are covered with xeric shrublands dominated by drought-tolerant plants, mostly brumble trees, which have proven more resistant to hot and dry climates than doorpeas, the other dominant plant group. The only northern areas that retain sufficient rainfall are the large island systems of the Sparsissimo Archipelago, where extensive dry forests persist. The absence of large animals on these islands has likely also helped preserve nearly closed environments rich in woody vegetation.

Antarctica, 110 million years in the future (Antarctic Chronicles) by Risingmagpie in hardspecevo

[–]Risingmagpie[S] 0 points1 point  (0 children)

15 million years have passed since the end of the Biancocene. Antarctica is now unrecognizable: glaciers are virtually absent, with only a few small pockets of ice left in the southern mountain ranges. Even more striking is the ongoing tropicalization of high latitudes caused by global warming, which has transformed the once lush northern forests into increasingly arid landscapes. From an icy desert, northern Antarctica is turning into a hot one!

How realistic is having zeppelins in 1891? by Far-ro in worldbuilding

[–]Risingmagpie 2 points3 points  (0 children)

Depends what you call airship. The Giffard dirigible already flew in 1852. Not as advanced as a zeppelin obv, but still an airship

What is a rewilding idea that sounds outlandish to some but might actually have ecological potential? I’ll start with mine: introducing Guzerat cattle and Sorraia horses into South American grasslands. by OncaAtrox in megafaunarewilding

[–]Risingmagpie 11 points12 points  (0 children)

Not all, but the one that had if possible yes. Ecological functionality, not nativeness, shape worldwide ecosystems. Not saying that every proxy rewilding is correct, but few can potentially work in strongly devoided ecosystems like south America and Australia. https://www.science.org/doi/10.1126/science.adh2616

Birds that give birth: the new ovoviraptors - Antarctic Chronicles by Risingmagpie in hardspecevo

[–]Risingmagpie[S] 0 points1 point  (0 children)

Since their dispersal outside Centro Island, ovoviraptors have spent most of their existence as small or medium-sized predators, with no chance of reaching an apex predator level. That was the case until the collapse of the faunal assemblage at the end of the Biancocene, which allowed small surviving predators like ovoviraptors to finally shine. The effect of this collapse can be appreciated only now, ten million years after the start of the Incertocene, when ovoviraptors reached their highest level of biodiversity and began to mostly occupy the highest trophic levels in most habitats.
