New paper alert! 🦜

We gave wild cockatoos puzzle boxes across Canberra’s urban gradient. The finding? Urban birds approach faster, but are not better solvers.

Our results suggest that urbanization shapes neophobia independently from cognitive performance. Read it here:

Climate, ecological dynamics, and the seasonal distribution of birds in mountains Ecological dynamics related to energy use and competition drives the seasonal distribution of birds in mountains across the world.

Why is there such variation in the birds encountered as you go up or down a mountain? New paper in #ScienceAdvances examines how climate and ecological interactions drive bird distributions in mountains throughout the year:

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

Why the Shape of Continents Mattered Across 500 Million Years of Climate Change New fossil evidence shows how geography influenced who survived Earth’s climate shifts

Extinction isn’t random.

Range size matters. Temperature tolerance matters. Climate change matters.

But there’s another piece we’ve long suspected: geography.

For 500 million years, the shape of continents helped shape survival.
