Integrative analysis of fine-scale local adaptation of winter moths to variable oak phenology For herbivorous insects whose fitness depends on tight phenological synchrony with host plants, spatial variation in plant phenology can impose strong selective pressures and promote local adaptation ...

New preprint! 🌳🐛

We combined experimental and genomic methods to study local adaptation of winter moths to variation in oak budburst timing in Wytham Woods, UK.

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! ⛈️ ❄️ 🔥

Combined effects can worsen outcomes! When chicks face extreme heat + heavy rain, their mass at fledging can reduce dramatically (up to 27% 🔥). 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 ⛈️

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

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! 🪶

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 🐣 🌍🔥❄️

@devisatarkar.bsky.social gave beautiful talk on the extent to which social network traits are heritable vs. shaped by the spatial & social environment at birth using long-term data on blue tits 🐣🧬

Thank you so much!!

Great tits show early signs of splitting up: researchers uncover social clues to bird 'divorce'

Wild great tits signal ‘divorce’ long before the breeding season — even in the winter, months before the couples rebreed with different partners in the following spring

New research shows that the early-life environment of great tits shapes their adult behaviour more than their genetics 🐦🍃.

Lovely to see Devi Satarkar’s first DPhil paper out in print

Had such a wonderful time at #ECBB2024 where I had the privilege of presenting my PhD work at an international conference for the first time ever! Beautiful city & campus and absolutely brilliant people & research 🤩

Thanks to everyone for being so encouraging about my work 🐣

@Ben_Sheldon_EGI @iremsepil

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!...

Presented my first ever poster at the @royalsociety conference on age and sociality this week and immensely enjoyed 2 days of really cool research and chatting with even cooler people 🤩

Massive thanks to the organisers for such an enlightening meeting ✨

Wonderful talk this evening by @WhySharksMatter at @morethanadodo. So many cool shark facts & anecdotes!

TIL that some female sharks can just birth clones of themselves🦈 they don’t need no man 🫢

Great insights on irresponsible conservation actions due to misinformation too

The review also has comprehensive descriptions of the structure and function of the receptor. Along with how it was discovered and how it came to be ✨

There's more about wound healing 🩹 in there too, with a special focus on zebrafish 🐟 research! @FrontCellDevBio

this.

Excited to share my 1st ever paper that got published last week! It's a #review on the role of CXCR3 (a chemokine receptor) in neuronal 🧠 and cardiovascular 🫀 diseases. Beyond grateful for @drchinmoypatra's encouragement and guidance as I wrote...
