Really looking forward to helping out on this! Please do spread the word if you or anyone in your groups would be interested!

Epigenetic Potential and Dispersal Propensity in a Free‐Living Songbird: A Spatial and Temporal Approach Natal dispersal is a key life history trait determining fitness and driving population dynamics, genetic structure, and species distributions. Despite existing evidence that not all phenotypes are eq...

Very excited about this work now out in
@molecology! We test whether🐦with ⬆️dispersal propensity differ in the nº CpGs across the genome, with the hypothesis that⬆️CpGs allow for⬆️epigenetically-driven plasticity facilitating environmental coping

Thanks Jannice - that is very helpful!

A while back (maybe 3-4 years?) there was a paper on common misconceptions of the genetics of various traits. One of them was eye colour in humans. I have lost this reference and can't find it anywhere. Does anyone recognise what I mean?

Host filtering and biogeography structure island bird gut microbiomes Gut microbiomes are central to host ecology and evolution, yet the mechanisms driving their diversification remain elusive, partly because host evolution and biogeography are often confounded. The rec...

Nice to see this preprint on the factors shaping Macaronesian chaffinch microbiomes out. A fantastic collaboration with @andalgalornis.bsky.social and his team. www.biorxiv.org/cgi/content/...

DeepKin: Predicting Relatedness From Low‐Coverage Genomes and Palaeogenomes With Convolutional Neural Networks DeepKin is a novel tool designed to predict relatedness from genomic data using convolutional neural networks (CNNs). Traditional methods for estimating relatedness often struggle when genomic data i...

Our genetic kinship estimation tool “DeepKin” is now available! Our neural network models trained on simulated data work effectively on real ancient data from diverse backgrounds and often outperform available tools. @compevohumang.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

I have arrived in Barcelona for ESEB 2025!

I will be talking about microRNA and the evolution of the mammalian placenta on Tuesday at 14:30 in Meeting Room 113
@eseb2025.bsky.social

🎤 Symposium: Evolution in Small Populations
I’ll be speaking on Evolutionary legacies of population collapse
🗓 Thursday, 11:00–13:15, Room 115

Looking forward to this #ESEB2025 week!

Oh. Embarrassingly easy 😂

Marina Martín Maroto (@marinamartinmaroto.bsky.social) Envision PhD Student at the University of Nottingham investigating urban adaptation in birds 🐦🏙

marinamartinmaroto.bsky.social and especially the extensive and impressive PhD work from @jack-harper.bsky.social who sadly isn't here (he's writing up)!

Also, I'm talking at #eseb2025 on the evolutionary history of a commensal species at 2 pm on Monday in S51-02. Come along to hear about how cool house sparrows are and all the exciting work from the sparrow team @melissahrowe.bsky.social @eriksroeed.bsky.social @ruthfawthrop.bsky.social

Ok firing up bluesky again because I'm back from paternity leave and heading to #eseb2025 (with the kids too)! Can someone help an old Dino out and show me how to follow the conference hashtag?

On my way to #ESEB2025 ! I’ll share some new results showing bi-directional introgression of structural variants, which cause resistance to different insecticides, between native and invasive agricultural pests 🐛 Monday 10:30am, S05 rooms 120-121

Interested in host-associated microbiomes? Attending @eseb2025.bsky.social? Then come check out Symposium S07 on Monday August 18th and hear all about how microbiomes contribute to adaptation. Gut microbiomes, climate change, thermal physiology, behaviour, invasion biology, blood-feeding, and more!

Three very happy people, including a PhD student who just successfully defended her PhD and her two supervisors standing in a sunny garden in Cambridge, UK.

Black hat with knitted butterflies, laminated real butterflies, a DNA strand missing a bit due to CRISPR knockout, colourful dots resembling a GWAS plot and a small butterfly net.

Happy people celebrating with a picnic in a garden in Cambridge, UK.

Dr Eva van der Heijden (first PhD in my group, not on Bluesky) finished her PhD with flying colours and a new hat! The hat represents her PhD with CRISPR DNA, butterflies, a tiny net, GWAS dots, etc. What a great day of celebration! @sangerinstitute.bsky.social @camzoology.bsky.social

Delighted to share our new review paper onlinelibrary.wiley.com/doi/10.1111/.... This was a whole-lab effort for my group ~2021, and these students were a dream team 🤩 (yes it took us 4 years...but I'll take credit for that...turns out having a baby in a pandemic slows things down 😜).

Looking without bias is very hard to do. We want to “let the data do the talking” but data must be interpreted against backgrounds that are not bias-free.
I want to tell you about an experiment showing how when looking at a plot, we come with bias that frames our perception.🧵⬇️

I made a starter pack of speciation researchers. Please let me know if you or someone you know would like to be added. I am particularly sad that so far there are not many speciation researchers from the Global South represented.

A high-resolution two-step evolution experiment in yeast reveals a shift from pleiotropic to modular adaptation Evolution is expected to involve mutations that are small and modular in effect, but recent findings suggest that mutations early in an adaptive process can have strong and pleiotropic effects. This s...

Do mutations that drive evolution improve many traits or few?

Does this change over the course of evolution?

Excited to share our work in PLOS Biology exploring these questions in the first 2 adaptive steps w/ Yuping Li, @gsherloc.bsky.social, @petrovadmitri.bsky.social 🧵

Question for those of you who do fieldwork and need high-molecular weight:

- How do you collect and transport your cold samples from remote fieldsites? Galápagos for me.
- Do you use a dry shipper? Do you fly with it?
- Do you use some service/company?

Any insight/reposts are very, very welcome!
