New paper out! 🖨️ Glad to be part of this study, out in Science Advances: "Emergent patterns of island biodiversity in the Anthropocene" www.science.org/doi/10.1126/... Much of what looks natural in island biodiversity is a legacy of human impacts going back millennia. See main findings 👇🧵 (1/8)

Emergent patterns of island biodiversity in the Anthropocene

Human impacts substantially affect our ability to detect and understand natural biodiversity patterns.

Thank you @jonastrepel.bsky.social for including me in these reflections! It has been a pleasure working with you and learning more about the impact of large terrestrial herbivores on plant communities! 🦏🌱 ⬇️ See below for the link to the @funecology.bsky.social paper and summary

Hurray - new paper out in Functional Ecology! @funecology.bsky.social @econovoau.bsky.social

I couldn’t agree more, Sir David! “It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living.” 🐿️🌺🌵🍄🐙🐠🦁🦜 Happy 💯 Birthday!

New Science Advances paper: 60 years of change across European plant communities reveals a widespread shift toward denser vegetation, with increasing shade tolerance across habitats. Proud to co-author this important work🍃 #ecology www.science.org/doi/10.1126/...

Sixty years of plant community change in Europe indicate a shift toward nutrient-richer and denser vegetation

Bioindication reveals a 60-year shift toward denser, more productive vegetation, but a weak thermophilization signal.

Es pot tenir una societat d’individus amb sentit crític sense coneixements científics? La ciència, la filosofia i, en particular, la teoria de l’evolució són puntals necessaris que s’han de reforçar, no debilitar, en el sistema educatiu. @ara.cat @ibe-barcelona.bsky.social

🚨 #PaperAlert! #Neanderthals were elephant gourmets, but also not picky eaters! Our new study at Lehringen (~125 ka) shows evidence of elephant butchery associated with a wooden spear, alongside the exploitation of bears, beavers, and ungulates. Flexible hunters with everything on the menu 🐘🍽️ 🦣🏺🧪

First time all my PhD students met in person! It was the perfect excuse to spent the day in Montseny Natural Park and setting camera traps for the wildcat monitoring project. A great day of fieldwork and teamwork! Marina, Natàlia, Ignasi, Nerea, Maria, I am very proud of all your hard work 💪🏻

New paper! 🚨 Nice collaboration with @predator-smarts.bsky.social and other colleagues on the role of predatory-prey interactions in shaping animals cognition 🧠 #cognition #brain #animals #macroevolution

How and why does cognition vary so greatly between individuals and species? In @natrevbiodiv.nature.com, we propose the "Predatory Intelligence Hypothesis" which posits that the cognitive challenges associated with predator–prey interactions drive a cognitive co-evolutionary arms race rdcu.be/e5KIj

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.

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.

It's MSCA results day. Congrats to all the successful applicants! Commiserations to those (including those I supported) who didn't make the cut. It was so competitive this year, even more than usual (>96.8% cut-off!). Be proud of your work and treat yourself to consolation cake/beverage/walk.
