How fat is an elephant?

We jumped the gun a bit in asking How fat was Camarasaurus? a couple of years ago, or indeed How fat was Brontosaurus? last year. As always, we should have started with extant taxa, to get a sense of how to relate bones to live animals — as we did with neck posture.

So here we go. I give you a herd of Indian elephants, Elephas maximus (from here):

You will notice, from this conveniently-close-to-anterior view, that their torsos bulge out sideways, much further than the limbs.

Now let’s take a look at the skeleton of the same animal in the Oxford University Museum of Natural History (downloaded from here but for some reason the photo has now gone away):

The rib-cage is tiny. It doesn’t even extend as far laterally as the position of the limb bones.

(And lest you think this is an oddity, do go and look at any mounted elephant skeleton of your choice, Indian or African. They’re all like this.)

What’s going on here?

Is Oxford’s elephant skeleton mounted incorrectly? More to the point, are all museums mounting their elephants incorrectly? Do elephants’ ribs project much more laterally in life?

Do elephants have a lot of body mass superficial to the rib-cage? If so, what is that mass? It’s hard to imagine they need a huge amount of muscle mass there, and it can’t be guts. Photos like this one, from the RVC’s televised elephant dissection on Inside Nature’s Giants, suggest the ribs are very close to the body surface:

I’m really not sure how to account for the discrepancy.

Were sauropods similarly much fatter than their mounted skeletons suggest? Either because we’re mounting their skeletons wrongly with the ribs too vertical, or because they had a lot of superficial body mass?

Consider this mounted Camarasaurus skeleton in the Dinosaur Hall at the Arizona Museum of Natural History (photo by N. Neenan Photography, CC-BY-SA):

Compare the breadth of its ribcage with that of the elephant above, and then think about how much body bulk should be added.

This should encourage palaeoartists involved in the All Yesterdays movement to dramatically bulk up at least some of their sauropod restorations.

It should also make us think twice about our mass estimates.

Dear PLOS ONE: time to sort out your multiple review tracks

Here at SV-POW!, we are an equal-opportunity criticiser of publishers: SpringerPLOS, Elsevier, the Royal Society, Nature, we don’t care. We call problems as we see them, where we see them. Here is one that has lingered for far too long. PLOS ONE’s journal information page says:

Too often a journal’s decision to publish a paper is dominated by what the Editor/s think is interesting and will gain greater readership — both of which are subjective judgments and lead to decisions which are frustrating and delay the publication of your work. PLOS ONE will rigorously peer-review your submissions and publish all papers that are judged to be technically sound.

Which is as we would expect it to be. But their reviewer guidelines page gives more detail as follows (emphasis added):

[Academic Editors] can employ a variety of methods, alone or in combination, to reach a decision in which they are confident:

  • They can conduct the peer review themselves, based on their own knowledge and experience
  • They can take further advice through discussion with other members of the editorial board
  • They can solicit reports from further referees

As has been noted in comments on this blog, this first form, in which the editor makes the decision alone, is “unlike any other first-tier academic journal”. When I submitted my own manuscript to PLOS ONE a few weeks ago, I did it in the expectation that it would be reviewed in the usual way, by two experts chosen by the editor, who would then use those reviews in conjunction with her own expertise to make a decision. I’d hate to think it would go down the easier track, and so not be accorded the recognition that a properly peer-reviewed article gets. (Merely discussing with other editors would also not constitute proper peer-review in many people’s eyes, so only the third track is really the whole deal.)

The problem here is not a widespread one. Back when we first discussed this in any detail, about 13% of PLOS ONE papers slipped through on the editor-only inside lane. But more recent figures (based on the 1,837 manuscripts that received a decision between 1st July and 30th September 2010) say that only 4.2% of articles take this track. Evidently the process was by then in decline; it’s a shame we don’t have more recent numbers.

But the real issue here is lack of transparency. Four and half years ago, Matt said “I really wish they’d just state the review track for each article–i.e., solo editor approved, multiple editor approved, or externally reviewed […] I also hope that authors are allowed to preferentially request ‘tougher’ review tracks”.

It seems that still isn’t done. Looking at this article, which at the time of writing is the most recent one published by PLOS ONE, there is a little “PEER REVIEWED” logo up at the top, but no detail of which track was taken. PLOS themselves evidently take the line that all three tracks constitute peer-review, as “Academic Editors are not employees […] they are external peer reviewers“.

So I call on PLOS ONE to either:

A. eliminate the non-traditional peer-review tracks, or

B1. Allow submitting authors to specify they want the traditional track, and

B2. Specify explicitly on each published paper which track was taken.

Who owns a peer-reviewed, revised, accepted manuscript? YOU DO!

Suppose that, for some good and sane reason, you need to place a paper in a paywalled journal.

You do some research. You write a paper and prepare illustrations. You send it off to a journal, and a volunteer editor sends it out to volunteer peer-reviewers. You handle the reviews, revise your manuscript, write rebuttals as necessary, send in the revised version, and the editor accepts it.

Congratulations! You are now the proud owner of a peer-reviewed, revised, accepted manuscript which will shortly become a published paper that you can put on your CV and show to grant reviewers and job-search committees and tenure boards.

Note the key point here: you are the owner of the accepted manuscript. Not the journal, not the publisher. You, the author.

Any minute now the publisher is going to ask you to sign a copyright transfer agreement. Once you do that (if for some reason you decide to acquiesce) they will own your work. From that moment on, whatever you’re allowed to do with your own work, if anything, is only by their grace.

Here’s the point: in between getting your acceptance and signing away all your rights, you have a window in which you own a completed scientific work, lacking only copy-editing (if any) and typesetting. So that is your moment to make sure the world sees it. Release it now. Put it it up on arXiv or on PeerJ Preprints or on FigShare or on your institutional repository or on your own web page. There are lots of places you can post it — take your pick. Either place it in the public domain or licence it as CC BY, and do it explicitly: both options make work available for the world to use, and either way academic norms will ensure that you get credit for your work.

Of course, once you sign over copyright, you’re playing by the publisher’s rules. They may well have crazy, complex, self-contradictory rules such as Elsevier’s you-can-deposit-it-unless-mandated-to rule — they can forbid you from making the accepted manuscript available.

That’s why it’s so important to release it to the world, with a clear statement of licence, before signing the copyright transfer. Once it’s out there in the public domain or as CC BY, it can’t be rescinded. The world can see and read and use and benefit from your work, and the “publisher” can’t prevent it.

So you can ignore Elsevier’s crazy requirements — just so long as you do it before you sign up to them.

(Once your work is out there for the world to use on liberal terms, you can of course go right ahead, sign the transfer, and let the publisher publish your article behind their paywall. That’s OK: the work is out there fore people to use. And if the publisher adds significant value in their copy-editing and typesetting, people will keep buying their subscriptions.)

 

The SV-POW! open-access decision tree

As part of the progressive erosion of RCUK’s initially excellent open-access policy, barrier-based publishers somehow got them to accept their “open-access decision tree“, which you can now find on page 7 of the toothless current version of the policy. The purpose of this manoeuvre by the Publishers Association is to lend an air of legitimacy to continuing to deny citizens access to the research they funded for up to 24 months after publication. It’s to the House of Lords’ enduring shame that they swallowed this, when they must know that there is no justification for embargoes of any length.

More recently, as commentary on the Australian Research Council’s open access policy, the Australian Open Access Support Group (AOASG) published its own rather better decision tree.

But it still doesn’t go nearly far enough. So here is the SV-POW! decision tree, which we encourage you to print out and hang on your office door.

… and don’t forget, when depositing your peer-reviewed accepted manuscripts in a repository, to specify that they are made available under the CC BY licence, which most benefits the field as a whole.
