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...

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...

Remember the summer heatwaves in the UK in 2026? The late May heatwave was exceptional: an event +4.3 sd above mean - likely to occur only once every few decades under normal conditions. It was also unusual in being early and coinciding with tit breeding season. What consequences did it have? 🧵1/n

Summary of 2026 summer 🔥 from @metoffice.gov.uk. Summer runs 1/6-31/8, so omits late May '26 heatwave, possibly even more anomalous in statistical terms. We have a new preprint led by @davididiaquez.bsky.social which analyses effects on growth & survival of Wytham tits 🧵⬇️ bsky.app/profile/davi...

Abstract. Phenotypic trade-offs, predicted to occur due to resource limitation, are not commonly detected. For this, the Y-model provides a powerful heuris
