I second the curiosity about oxygen production - what % do you have the ocean producing? I often see ~50% as well (not air as the article states, but O2 as you say)

I want to end by saying how special this article was to lead. It really was a beautiful team effort that brought it together, and I am very proud to have represented the Isthmus and #STRI #Smithsonian with this work. SCIENCE SHOULD BE COLLABORATIVE AND MEANINGFUL. I hope you agree, and enjoy!

This was all part of the wonderful special edition "Shifting Seas: Understanding Deep-Time Human Impacts on Marine Ecosystems" in @royalsocietypublishing.org led by editor @lukeeholman.bsky.social

This would COULD NOT BE POSSIBLE without my wonderful co-authors and discipline experts (most not on BS) such as: @erinmdillon.bsky.social @odealab.bsky.social and the rest

We tried hard to fuse stories of oceans, climate, biodiversity, and early human systems to bring focus to this incredible region of study, with a hope and a need to attract more attention to it in the future!

Our work emphasises the importance of ocean–land connections for Isthmian peoples and the critical balance of livlihoods, research, and conservation efforts needed to ensure its future sustainability.

We identified three major transitions of Isthmian peoples relationships with the #ocean and its resources:
1) The shift to agriculture after megafauna extinction,
2) rising sea levels and the novel ecosystems they created,
3) Spanish colonisation and the globalisation of resource extraction

Using #STRI's vast zooarch collections, we found intersting diet trends showing the diversity of ecosystems peoples relied on over many thousands of years

My fav part was the incredible case-studies co-authors #nicole #brigida #irene @odealab.bsky.social @erinmdillon.bsky.social told about shell fishing, the pearl oyster industry, and the history of indigenous peoples under Spanish occupation.

Our proudly interdisciplinary team of paleobiologists, archaeologists, anthropologists, and global change researchers worked hard to combine vast datasets that would be intersting to a wide suite of readers. Everything from zooarchaeology to sea level change!
