Fossil isotope evidence for trophic simplification on modern Caribbean reefs - Nature Using nitrogen isotopes from ancient and modern fish otoliths and corals, the study shows Caribbean reef food webs are now 60–70% shorter and functionally less diverse, indicating human-driven trophic simplification and increased risk of collapse.

Gonzalo Salazar has his first thesis paper published today in @peerj.bsky.social

We show that the invert taxa of the very understudied salares of the Lithium Triangle differ greatly between sites and will need assessing individually
