#isoecol2026 is now live for abstract and workshop submission! Come join us in Hong Kong! DM with any questions and please share!

Thank you for coming!

Thanks to my amazing coauthors: Rodnyel Arosemena, @jonscibulski.bsky.social , Brígida De Gracia, @sethf.bsky.social , @otolith-lin.bsky.social , Javiera Mora, Sven Pallacks, and @odealab.bsky.social !

By analyzing thousands of otoliths preserved in sediments, we found that fish were larger on average at death on reefs in Pacific Panama, compared to those along the Caribbean coast, and that this difference has widened over time.

New paper out today! "Fossil otolith assemblages reveal millennial-scale changes in reef fish biomass and trophic structure across the Isthmus of Panama" 🔓https://doi.org/10.1098/rstb.2024.0419 We used fossil fish otoliths to reconstruct community structure and energetics over millennia.

The @swimshku.bsky.social whale has returned!

Final reminder to consider submitting an abstract to join our thematic session on "Reefs through time" at the @icrs.bsky.social meeting next July. The call for abstracts closes Dec 1! See below for details. Hope to see you there!

We are so excited to welcome such a great addition to #HKU Science! Can't wait to collaborate!

New paper alert! "Isotopic evidence of increased societal diversification in Pre-Columbian Panama" www.researchgate.net/publication/...

New paper alert! See press release here! Palaeonology: A small subject has big questions www.fau.eu/2025/09/news...

Work on reef paleoecology? Join our session "Reefs through time: leveraging today's interdisciplinary tools to better understand the past of reef organisms and ecosystems" at the 2026 International Coral Reef Symposium 📆Abstract deadline: Dec 1, 2025 🔗https://www.icrs2026.nz/call-for-abstracts

Our @icrs.bsky.social 2026 session is now open for abstract submission! Consider it if you work on reef systems through time!

📊 new paper! The natural phenomenon of upwelling, which normally occurs every year in the Gulf of Panama, failed for the first time on record in 2025... www.pnas.org/doi/10.1073/... [most co-authors not on bluesky except @javsdiaz.bsky.social @jonscibulski.bsky.social]...

SWIMS will be a very busy place from tomorrow because Integrative Marine Ecology & Conservation (IMEC) MSc has launched! Tomorrow, forty-four students will start their journey at SWIMS and HKU. Their first class – Ocean Biodiversity, is at 9am. Welcome to SWIMS, everyone! @jonscibulski.bsky.social

Dr Jon Cybulski @jonscibulski.bsky.social talks about the story of his latest paper: Historical Ecology of the Southern Central American Pacific Coast. With @odealab.bsky.social More: royalsocietypublishing.org/doi/10.1098/... #marinescience #centralamerica #humanspecies #sustainability

Awesome postdoc opportunity with some really great people. If you are interested in spatial paleoecology, take a look and spread the word!

I have never been more honoured. My overhead mobility looking great.

🌊Just out! We reviewed the history of human-ocean interactions, focusing on the Pacific coast of the Southern Central Asmerican Isthmus (Panamá and Costa Rica). Over 16K years of stories on culture, environment, and ecology! royalsocietypublishing.org/doi/epdf/10.... Illustration: Madeline Dall

Very excited for our new @pnas.org manuscript investigating changes in “big and little fish” ecology over the last several thousand years in the Caribbean! See awesome thread by @odealab.bsky.social below. Go collaborative science team!!
