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/...

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...

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.

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

Johan Renaudie @plannapus.bsky.social · Mar 26

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?

Johan Renaudie @plannapus.bsky.social · Mar 4

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

Johan Renaudie @plannapus.bsky.social · Mar 4

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.

Johan Renaudie @plannapus.bsky.social · Nov 26

[...] 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

"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.

Johan Renaudie @plannapus.bsky.social · Oct 29

Do you happen to have pictures of other focal depths?
