Fossils for Future: the billion-dollar case for paleontology’s digital infrastructure
DOI: doi.org/10.32942/X2D...

BioDeeptime has made it into Science! "Climate is changing fast—and forests are 200 years behind". A sweeping new analysis of ancient pollen and modern data reveals this dramatic lag—and its consequences."(from ScienceDaily) - article: DOI: 10.1126/science.adr6700 CONGRATULATIONS to the authors.

Coupled, decoupled, and abrupt responses of vegetation to climate across timescales Climate and ecosystem dynamics vary across timescales, but research into climate-driven vegetation dynamics usually focuses on singular timescales. We developed a spectral analysis–based approach that...

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/...

Indeed it seems to work again. I hadnt been able to reach anything since a couple of days.

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.

Now published online in Current Biology! www.cell.com/current-biol...

And it is finally out! bg.copernicus.org/articles/22/...

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.

OK :) So yes 15% seems high indeed.

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.

I deleted my account two months ago.

[...] 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

While most of the twitter folks that I followed from english-speaking countries (and to some extent from South America) made it here, I am still missing the others: namely my Japanese colleagues (which were making the bulk of Micropaleontology Twitter) are not here yet, [...] 1/2

A group of radiolarians isolated from a plankton tow.

A bunch of cells of the nasselarian radiolarian Plagiacantha arachnoides--like a group of little spiders! Plus a couple of bonus acantharians. From the gulf of maine #protistaday #protistsonsky #marinelife

Certainly sturdier than Woodhenge and Hayhenge at least.

Functional and Character Disparity Are Decoupled in Turtle Mandibles Here, we compare functional disparity measured by biomechanical proxies and character disparity measured by discrete morphological characters in turtle jaws. Exploration of mandibular patterns reveal...

Second paper in Ecology & Evolution out in two consecutive days! 🐢🤩🐢

I guess the German chancellor would call this a "Doppel-Wumms" 😜

"The death of an acantharian" Or: why we don't have fossil acantharian skeletons like we do for their glassy and chalky cousins. I think in this case it might somehow be an active process--acantharian skeletons from cells that swarm away last longer.

Sarah, Dave and I just got a small piece published in PAGES Magazine on the legacy of IODP in term of evolutionary studies and conservation biology (with radiolarians as case study): doi.org/10.22498/pag...

Indeed my first guess would be some sort of pyloniid/tholoniid but i'm intrigued by what we see below in the middle of the specimen (are those arches? could it be some weird little nassellarian, like a trissocyclid). With additional pics showing different focal depths, it could clarify what it is.

Do you happen to have pictures of other focal depths?

Happy to have collaborated on this with Miguel! A new time-calibrated molecular phylogeny of radiolarians with insights on their hidden diversity 🧪

Radiolaria are known for their elaborate and gorgeous skeletons, found all over our oceans. But what if I tell you that half of their diversity might be naked!?

Hi! I'd like to be added to the feed if possible. Thanks!

Late Eocene to early Oligocene productivity events in the proto-Southern Ocean and correlation to climate change Abstract. The Eocene–Oligocene transition (EOT, ca. 40–33 Ma) marks a transformation from a largely ice-free to an icehouse climate mode that is well recorded by oxygen-stable isotopes and sea surface...

New article from our student Gabrielle, on Late Eocene paleoproductivity in the Southern Ocean! 🧪

The result seems more congruent with model expectations (i.e. instead of a sharp increase, a mostly stable history, with a slightly decreasing trend).
