Hugely proud of @sgavirneni.bsky.social for his first paper published last week in Paleobiology. With Linda Ivany, we linked marine #bivalve #extinction risk to adult resting metabolic rate (both whole-body total and mass-specific) over the past 300 million years... [1/5]

Metabolic traits are shaped by phylogenetic conservatism and environment, not just body size | PNAS Metabolic rate dictates life’s tempo, yet how ecological and environmental factors integrate to shape metabolic traits remains contentious. Conside...

Awesome to see our paper exploring competing hypotheses in macro/metabolic ecology out in PNAS.

Led by the all star @lilyleahy.bsky.social with a range of amazing folks including @funkyant.bsky.social @natejsanders.bsky.social @ianjwright.bsky.social.

Sadly leaving #sebconference to return home, but I'm blown away by the quality of talks, the careful methods, theory-led focus and awesome data across a wide breadth of systems, taxa etc. Makes an otolith geochemist feel inadequate. Thanks for having me & see you again @sebiology.bsky.social

Well that was close - having just had my Eurostar train cancelled - I think I managed to get the last available seat on the last train out tomorrow - so I WILL be there (although potentially quite tired) on Weds.

The final paper of my UoS postdoc is out now in PNAS! How to detect developmental plasticity in the fossil record:

Enjoy!! Sorry I’m heading in the opposite direction for SEB in Antwerp. See you next year in Southampton!!

If anyone at #SEBconference in Antwerp this week wants to hear about field metabolic rates in pelagic fishes (from otolith isotope analysis), I'll be talking on Wednesday - and happy to meet up / chat if schedules allign and you reply to this!

Hiring a marine biology lecturer at @universityofessex.bsky.social! Permanent position. Deadline to apply= 20 Aug. We have aquaria, lots of mass specs/genomic facilities, field trips to Crotia, Indonesia, Scotland and a super collegial department. Pls share!
