Paleoecology postdoc based in 🇩🇰/🇦🇺. I study past/present extinctions so we can stop future ones. Currently working on Arctic megafauna 🐋. Alaskan. FRY-myoo-ler
Pinned
Yesterday I successfully defended my joint-PhD between the University of Copenhagen and the University of Adelaide! I am now officially Dr. Nick!
And I also received favorable reviews and minor revisions on my two in-review chapters the same day!

Nice to see conservation policy outcomes from simple ideas
20+ yrs ago I had access to remote areas of Kuwait/Iraq, & saw its potential as bull shark 🦈 nursery habitat
Then spent 10+ years collecting evidence to back this up shorturl.at/0Cm0f
Now designated an Important Shark & Ray Area

It's well known that Bowheads live to be 200+ years old but here's a bonkers thing that we didn't realize until we had Nick on the pod - that means a whale alive today could potentially have been alive before whaling started AND they lived through the decades of whaling & the century of recovery🤯

I use BHL every single day in my research and teaching. I could not write my books or articles without it, I don't know what my students would do without it, and I would have to radically rethink my career without it. This is more critical with funding cuts. Please, please someone support BHL.
Foundations: please step up and take over the Biodiversity Heritage Library (BHL). This is an absolutely essential scanned archive of all of the old journals and books from the 1500s to about 1920. Has been indispensable for my research.
