New paper emerging from our Paleosynthesis project @paleosynth.bsky.social.
In www.nature.com/articles/s41..., we highlight the value of databases to #paleontology and the importantce of sustained funding. Our finding are probably applicable to other science fields as well.

What do we want?
Fossil databases! πŸšπŸ¦•
When do we want them?
Forever! πŸ—“οΈ
Nice new paper highlighting how academic funding systems and digital architecture need to change, to ensure we can protect and sustain our precious fossil data πŸ“š

(not that it compares to the evil of his theories on social darwinism but people still idolizing his naturalist work rubs me the wrong way)

Also he was a fraud. There is quite a lengthy literature on the fraudulent aspect of the embryos illustrating the 'ontogeny recapitulates philogeny' and, speaking as a radiolarian specialist, many of the radiolarian specimens he illustrated are at best chimeras or whatever fitted his theories.

Yes indeed, it s a feature they added only a couple of years ago so i would image most people don t know about it.
Similarly there was a time when there was no link to the paper on those pages.

That and the 'Download' and 'Request' button are identical, and at the same place.

If ResearchGate had a way to cancel a request, it wouldn't be an issue. The way the pages are designed, the button to request/download the paper is very prominent but the licence or the link to the paper isn't. And once you realize you just asked for a copy of an open access paper, it is too late.

Conceptual models of ice-sheet extent and associated depositional processes along a transect. During peak interglacials with inland ice-sheet retreat, icebergs calve from the retreating ice margin and drift onto the Amundsen Sea shelf. As these icebergs ground and melt, they release most of their detritus on the shelf. During early glacial stages, the ice masses around the Amundsen Sea embayment could regrow rapidly and coalesce into an ice sheet. The advancing grounded ice β€œbulldozed” the sediments, which had accumulated on the shelf during the previous interglacial, toward the shelf break. From there, the fine-grained detritus is transported down to the continental slope mainly by gravitational processes.

West Antarctic Ice Sheet glaciers underwent at least five major inland retreats during the Plioceneβ€”a period with temperatures similar to projected future warmingβ€”suggesting the possibility of meter-scale global sea-level rise in our future. In PNAS: https://ow.ly/I6NZ50XRaap

Vegetation might not be able to keep up with current rates of environmental change, given data from the pollen fossil record. Fun doing this work with David Fastovich in the lead, but sobering www.science.org/doi/10.1126/...

Is it just for me or are all the IODP Proceedings currently unreachable? I'm getting Error 403 on all of them and the individual DOIs lead to Error: DOI not found.

sorry i meant setdiff(tree$tip.label, rownames(Ages))

You would need to check setdiff(names(tree$tip.label),rownames(Ages)) in order to compare properly instead of just names(tree). tree is a list object that contain the names of the tips, the shapes of the edges, and potentially many more items.

Are you looking for a specific taxonomic group?

So given most taxonomists started publishing names before 2011 and in journal with physical copies, they might not even be aware of the existence of zoobank, and/or don't see the point of entering name (i. e. doing extra work) in it if they don't have to. That would be my guess. 2/2

Since 2011, the code of zoological nomenclature was amended to say that new names have to be entered in zoobank, IF they are published in an online-only journal. 1/2

I also have an account on Mastodon. I like it personally but only the few people I followed who were tech-oriented made the jump, perhaps unsurprisingly.

[...] my former institution in Germany and most of the people working there also did not make the jump, and (most damaging for me) i am also missing all the regional news/politicians from the region i am from in Southern France. 2/2
