Happy to share out latest work in Ecology Letters!

We show how how genetic differences in plasticity determine fitness at different environmental scales from native to novel elevations.

Many thanks to the reviewers!

Our new pre-print (with @erichagen.bsky.social, @latinorchidbot.bsky.social, @jameswclark.bsky.social , Elizabeth Forward and Nick Priest) reveals rapid pollinator evolution in orchids, but no clear impact on diversification. Perhaps pollinator specialisation is not such a powerful force. 🐝🌱

Uncertainty in the timing of diversification of flowering plants rests with equivocal interpretation of their fossil record | Royal Society Open Science The timing of the origin of crown-angiosperms exemplifies the impact of competing approaches to establishing evolutionary timescales. Fossils of unequivocal crown-angiosperms are not known from before...

Our latest, led by @jameswclark.bsky.social of @milnerevolution.bsky.social shows that the notorious mismatch between molecular and palaeontological estimates for the timing of origin of angiosperms is a consequence of equivocal interpretation of their fossil record @bristolpalaeo.bsky.social

Delighted to see this paper from danderson123.bsky.social 's PhD out. We have been building tools for AMR gene detection for over a decade now, but multicopy genes remain challenging. Dan shows that with a gene-space de Bruijn graph and long reads, you can do well

Our 2025 Irene Manton Prize winner is Dr Jamie B Thompson! His research into the diversification of flowering plants is revolutionising our understanding of biodiversity, showing that they weren't wiped out by the asteroid that killed the dinosaurs. @jamiet-E442.bsky.social

Dating Bacteria is hard due to the lack of maxima. Assuming aerobes likely postdated the GOE gave us better resolved ages, but also surprised us, but not Dr Dayhoff, showing O2 use predated its atmospheric rise by 900 Mys and helped oxygenic photosynthesis to evolve. www.science.org/doi/10.1126/...
