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)
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...

Our study offers crucial insights into how wild populations may fare amid ongoing climate change, revealing how life history trajectories are shaped by interacting climate stressors and prevailing environmental conditions. Highly relevant as extreme events increase in frequency and intensity! βοΈ βοΈ π₯

Combined effects can worsen outcomes! When chicks face extreme heat + heavy rain, their mass at fledging can reduce dramatically (up to 27% π₯). Timing is also important. Late broods within a season are predicted to suffer the most, fledging up to 35% lighter under extreme heat and rain βοΈ

We show that cold snaps hit young hatchlings hardest, while older nestlings are more affected by extreme rain and heat β likely because these conditions indirectly influence the abundance and activity of caterpillars, the great titβs main food source π

Figure from the paper showing that extreme climatic events interact with ambient climatic conditions and breeding timing within a season, in a developmental stage-specific manner, to influence nestling growth in great tits
New preprint! πͺΆ
We analysed 60 years of data on 83,000+ great tits to show how extreme climate impacts on nestling growth and survival are stage-specific and context-dependent π£ ππ₯βοΈ

Great tits show early signs of splitting up: researchers uncover social clues to bird 'divorce'
Wild great tits signal βdivorceβ long before the breeding season β even in the winter, months before the couples rebreed with different partners in the following spring

Excited to share the first preprint from my PhD https://doi.org/10.1101/2024.07.11.603055 Turns out social phenotypes are not heritable in great tits!
Presenting this at #ECBB2024 tomorrow (10 am, Meerkat room). Please come along if you like social networks and birds!...

Wonderful talk this evening by @WhySharksMatter at @morethanadodo. So many cool shark facts & anecdotes!
TIL that some female sharks can just birth clones of themselvesπ¦ they donβt need no man π«’
