Subject: Repost: An alternative to the Companion Volume?
I am reposting this (with a few small modifications) because I think = this year's congress season is over, so more people might read it now than= the first time... ----- Original Message ----- =46rom: "David Marjanovic" <email@example.com> Sent: Friday, October 21, 2005 7:14 PM I apologize for the somewhat unusual length; I think this matter is v= ery important. Please bear with me. The idea of having a Companion Volume is to avoid having a gold rush,= a competitive race where people run to get their favorite names and definitions registered first. I wholeheartedly agree with this intent= ion. But the Companion Volume may not be an effective way to implement it.= It has two potential big problems: - If too few people contribute as authors and editors, the risk rises= that unwise* or unpopular names or definitions could be set in stone. This would just about automatically lead the LARGE number of systematists who have never heard of phylogenetic nomenclature to despise it, and perhaps it would even drive away some current adherents. If the numbe= r of people in EITHER group becomes too large, the PhyloCode will go the way of the BioCode. - If too many people are involved, it will never reach publication. * =3D will produce confusion when the topology changes in unforeseen = but foreseeable ways. The balance between these dangers is probably _very_ difficult to fin= d, and if we run out of luck, that balance might itself lie in an undesi= rable place (like containing many largely wise but rather unpopular names a= nd definitions _and_ being published 10 years from now). Therefore I would like to suggest an, in my humble opinion, safer alternative: Instead of having one volume published at once, we could spread the work over time -- by implementing the PhyloCode piecemeal. Here's how I imagine that: 1. On the website, and maybe in the first issue of the Society's jour= nal, we post a notice that people are encouraged to publish papers (prefer= ably collaboratively) on the nomenclature of their favorite clades. Such p= apers already exist; two examples (from tetrapods, where -- unfortunately -= - almost all of the current discussion on PN happens) are cited below. _____Maybe the publication of such papers should be restricted to the Society's journal. This way we would make sure that we wouldn't miss = any of them, and that all would abide to the PhyloCode. The disadvantage = would be that it would (probably) slow down the whole process. 2. The names in such a publication become _provisionally registered_. 3. A certain amount of time later (what about some five to ten years?= ) the Committee on Phylogenetic Nomenclature (or whatever part or appointee= s thereof) looks what has become of the names in that paper: Are they b= eing used? Are they being ignored? Are they still being discussed? _____If they are in general use, the CPN changes their registration f= rom provisional to durable (except maybe if the authors do not want this= =20 anymore); see the fourth point. _____If they are being ignored, the CPN deletes them from the registr= ation database. _____If the discussion is still going on, it won't be interrupted -- = the CPN extends the time of provisional registration by another term. _____Depending on the CPN's workload, the duration of a term should b= e considered a minimum (if the CPN has too much to do, it can simply consider the issue later; all terms are automatically extended to the= point=20 at which the CPN makes a decision). 4. Upon durable registration, the authors of the names stay the same,= and priority sets in. I'm not sure if the year and the registration numbe= r should change to reflect the date of durable registration, or whether= they should stay, too, which might make the Code retroactive. This issue n= eeds discussion. 5. After the nomenclature of a part of the tree has been set in stone= in this way, anyone can name newly discovered clades in that part and ca= n immediately register them durably, but should maybe not need to do so= . (This should probably be restricted to new, as opposed to converted, = names.) In other words, each part of the tree gets its own Companion Volume a= nd its own date for the implementation of the PhyloCode. _____There is, by the way, a precedent for this: under the ICZN, prio= rity starts in 1758, except for the spiders which start in 1751. (This particular publication is simply declared by the ICZN to have been published in 1758. We don't need to do such nonsense, we have the registration numbers.) I hope to have started a vigorous discussion (and to have elevated th= e impact factor of PaleoBios by an order of magnitude ;-) )! Addendum: It may not be easy to just cancel the Companion Volume; I hear there = is already a hopeful publisher, and so on. But dropping it may not be necessary. As Mike Taylor has pointed out onlist: "I'd just like to point out that David's proposal does not [necessari= ly]=20 entail discarding the Companion Volume -- merely that the definitions proposed in that volume, like all others, would originally be _provisionally_ registered, to be affirmed or rejected after a reasonable length of time. That way, we'd avoid painting ourselves into a corner." I can see two potential advantages in this particular approach: - It would greatly lower the threshold on who is enough of an "expert= " to contribute. So if, for example, we don't find an entomologist, we sim= ply define Hexapoda, Insecta, Pterygota etc. ourselves and let the entomologists discuss that. Ideally this would force them to familiar= ize themselves with PN and to start discussing definitions with each othe= r. - It might speed up publication because it would spare the editors th= e decision of whose preferred names get into the Companion Volume -- si= mply include all of them! On the other hand, it might (!) be a good thing = if our first publication were internally consistent. :-) References: - Walter G. Joyce, John F.
