Latest work from @devisatarkar.bsky.social DPhil thesis exploring the ecological effects that modulate the link between offspring and adult body mass in great tits. The correlation is really quite plastic! Fun collaboration with @lbliard.bsky.social @iremsepil.bsky.social @davididiaquez.bsky.social

Heavier great tit nestlings 🐥 usually end up as heavier adults 🐦. Is this always a strong correlation? Our new preprint shows that the strength of this 'silver-spoon' association shifts continuously with environmental context, and is stronger in harsh conditions! www.biorxiv.org/content/10.6...

🚨Preprint alert! 🚨What if your study animal doesn't know the landscape yet? Standard movement models such as SSA assume it does. In our new study we let it learn instead, and put "learner" against "omniscient" head to head (1/4) doi.org/10.64898/202...

New preprint out with Michael Griesser and @ryangermain.bsky.social, for some comparative analyses in which we find that population growth rates of cooperative breeders are less sensitive to annual variation in precipitation and temperature doi.org/10.32942/X26...

🚨Update: Our analysis of global APC expenditure has now been expanded to cover more publishers (7 -> 14) and more years (2019-2025). We estimate $15B in APCs paid over seven years, $3.7B in 2025 alone. Elsevier crosses the $1B threshold by itself in 2025. arxiv.org/abs/2608.16322 #ScholComm

An interesting article here about publication costs: www.horizons-mag.ch/2026/06/04/t... From 1 January 2027, @snsf.ch will cap the maximum publication fee at CHF 3,500, and will no longer cover fees that are higher than this, not even partially. www.snf.ch/en/G2XqbkM4D...

In a sea of opinions about the role of LLMs in academics I offer my own. Apart from being harmful, exploitive plagiarism machines, LLMs rob us of the opportunity to experience the gift of friction in writing, which changes how we think. We must not give away that gift. doi.org/10.1002/fee....

We have published a new pre-print showing a decline in great tit adult and nestling mass of around 1 gram in 47 y. [rate of approx. -0.040 Hadanes] With @ellafcole.bsky.social, @devisatarkar.bsky.social, Sam. Crofts, @mcmahok.bsky.social & @sheldonbirds.bsky.social www.biorxiv.org/content/10.6...
Decline in body mass in adult (left) and nestling great tits. In the nestling plot, the purple line represents all nestling and the green line those that recruited to the population as breeders. Their different slope suggest an increase in the strength of selection on nestling mass something confirmed in the MS by analysing the temporal trends in selection differentials (see link for further information)
