Local genetic reference sequences can be essential for species specific studies. Applying what worked for a species elsewhere in the world (in this case largetooth sawfish, Pristis pristis) may not work where you are!!! www.biorxiv.org/content/10.1...

Yesterday our new #globalsharktrends paper came out in @science.org
@nickdulvy.bsky.social did a great thread on the paper and included some GIFs that we had made but they did not play here on @bsky.app
I'm hoping this now works.

This is such a fantastic resource amazingly led by Rima Jabado et al.! Happy to have played a very minor part as contributor to the chapter on São Tomé and Príncipe led by @gporrinos.bsky.social. Well done to the 353 contributors from over 110 countries! #OceanOptimism #Conservation

Shifting baseline syndrome explains how we normalise the continual visceration of once unimaginably rich ecosystems.

Rewilding – our minds, lands, and seas – is the solution. 🌏

The IUCN SSC SSG was established to respond to growing awareness and concern of the severe impact of fisheries on shark, ray, and chimaera populations globally. The SSG is recognized as the leading authority on the status of these species, using science to support actions for conservation.
