Why did some #megafauna survive? 🦣🦘🦌
Our new study shows #extinction risk was higher for larger, flat-footed, island species— and lower for those closely related to tropical African/Asian fauna, likely filtered by earlier human impacts 👣🍖

Beavers are poised to invade and radically remake the Arctic A warming climate is enabling rodents to move north

🦫 The end of widespread fur trapping has allowed beavers to recolonize many parts of North America where they had been eliminated, but rising average temps is major factor in the advance.

‘Things keep evolving into anteaters.’ Odd animals arose at least 12 separate times Findings speak to the dramatic impact ants and termites can have on mammalian evolution

Crab-like creatures are famed for having evolved five times in evolutionary history. But anteaters have evolved at least 12 times--in half the evolutionary span. Cool story by @jakebuehler.bsky.social for @science.org

Impacts of proactive health management on cattle and horse diets and dung biodiversity in Danish rewilding areas Our findings demonstrate functional differences between cattle and horses, which suggest complementary effects on vegetation development and consequently biodiversity. Also, our results indicate that....

Key results:
Diets and dung-communities differ between cattle and horses, and feeding affects diets, but effects depend on intensity!

Figure from the paper showing our model results when considering the tropical vegetaiton collapse - a long-high temperature period following the PTME

Great to see this finally out today! We show that the collapse of tropical vegetation during the Permo-Triassic extinction is a key driver of the long-term super-greenhouse climate that followed it.
