We whole genome sequenced ancient and modern Bluefin tuna and find evidence for a demographic decline beginning around the year 1900, and a loss of genetic diversity. Collab between @Unibo @archaeogenomics and many fantastic ecologists and archaeologists pnas.org/doi/10.1073/pn…

@chris_harrod Unfortunately not from the same specimens, not sure what the offsets are but I can share some values from the literature i cobbled together. Challenging because of variety of methods for muscle (whole vs collagen, fat vs defatted etc)

@AdamJonAndrews - do you have muscle-collagen comparisons for tuna?

fishy isotope people - anyone got C & N TDFs for diet-collagen? I have the Guiry & Hunt 2002 paper doi.org/10.1016/j.mare…

@CPampoulie @York_BioArCh @MMAlexande Cheers Chris, was great to work together - hopefully not for the last time ;)

Using stable isotope analyses of archaeological bones, we find Atlantic bluefin tuna have become more pelagic in recent centuries and lost a Black Sea trophic niche by the 1980s—likely due to exploitation. Great collab with @York_BioArCh and @MMAlexande doi.org/10.1111/faf.12…

I’m so pleased to share our new paper, which came out yesterday in @PNASNews pnas.org/doi/10.1073/pn…

@ZooArchGIA @SeaChangesITN Thanks so much Canan 😊

Very happy to have served in the examination committee* of this wonderful @SeaChangesITN ESR. Good luck *Was not much work...he'd already done a cum laude job. Good luck Adam and congrats to Bologna aDNA team!!!

🧬🐟Here is our preprint "Unidirectional trans-Atlantic gene flow and a mixed spawning area shape the genetic connectivity of Atlantic bluefin tuna" @ICES_ASC @planettunaIEO @FAOfish #ICCAT. We show that: doi.org/10.22541/au.16…

PhD cum laude ✅ Thankful for a great few years in Bologna and delighted to announce I will begin a permanent research position @NIVAforskning in Oslo 🇳🇴 in September 🥳 Excited to work on ecosystem consequences of offshore wind and contribute towards the green transition 🌍

Hello @AdamJonAndrews ! You are our 300th follower 🥳 - welcome to #SeaBeeNorway! Make sure you head over to seabee.no to check out the latest developments in the SeaBee Research Infrastructure 😃 #drones #datacollection #CloudComputing

Very nice multi-disciplinary summer school on human impacts organized by Canan @ZooArchGIA and others

Studying 2,242 pops worldwide from 369 species, we show that recent disturbance regimes do not predict resilience potential. @Ecology_Letters paper led by @I_CAN_actually, w @PolCapdevila90 & @MariaBeger. Layman's summary: biology.ox.ac.uk/article/resili… @OxfordBiology @PembrokeOxford

Pleasure to be a part of the @palaeovc which is kicking off today… Presenting on my PhD findings, how historical ecology has value for policy, and also the challenges of making these data relevant. Thanks to the organisers and to a good friend @PAbondio

how i feel when my paper gets 1 citation #Coronation

We found clawed lobsters exhibit greater differentiation than spinys, both rangewide & within basins, and show that the hydrographic & topographic barriers separating the Atlantic from the Mediterranean form the strongest genetic break in both species. 🦞

@chris_harrod @UoYArchaeology @TheFSBI Yes yes, will you make it?

@AdamJonAndrews @UoYArchaeology @TheFSBI For the otolith meeting?

Delighted to see our article in collaboration with @UoYArchaeology out in @TheFSBI onlinelibrary.wiley.com/doi/10.1111/jf… We looked at the variation in stable isotopes across vertebrae 🦴 centra in Atlantic bluefin tuna 🐟 and found multiple years of foraging behavior are likely archived!

@chris_harrod @UoYArchaeology @TheFSBI Thanks Chris - hope to see you in Chile in October!

@AdamJonAndrews @UoYArchaeology @TheFSBI lovely stuff! well done Adam

Similar patterns were observed in archaeological vertebrae - meaning life histories can be reconstructed also for ancient fish. Results likely to be transferable to other teleosts since tuna is probably one of the most rapidly remodeling species!

Remodeling rates are unknown but our work suggests remodeling is sufficiently slow to retain significant isotopic variation, but not all years since juvenile signatures (really low 13C, 15N) were not observed
