[CPN] CPN action needed on species proposal

[Cantino, Philip]

Dear CPN,

Thank you, Dave, for returning the CPN to the task at hand.  Now that everyone has presumably returned from fieldwork and vacations, I hope we can bring this matter quickly to a conclusion.

Regarding item 2 in your list, I suggest that we broaden it to Art. 21 in general rather than David M's specific recommendations, because other people may have additional changes to recommend in this article.

In addition, I would like the CPN to consider adopting the following changes that were proposed by (or at least related to the proposals of) CBM:
1) Modify the Preamble to the wording suggested by CPN
2) Delete Note 3.1.1
3) Reword Art. 9.7 (but the modification I prefer differs from that recommended by CBM); see below.
4) Reword Rec. 9c (but the modification I prefer differs from that recommended by CBM); see below.
5) Delete Rec. 11.4B (because I don't think this code should recommend what people do under the rank-based codes.  What the recommendation suggests is simply sensible nomenclatural practice and therefore likely to be done anyway).

Regarding my item 3 (Art. 9.7), which concerns the required statement about the hypothesized composition of the named clade, I want to retain the option of citing species (contrary to CBM) but add a requirement that if specimens are cited in the composition statement (as may be done by authors who agree with CBM's perspective), then the author must also include the name of a species or clade (less inclusive than the one whose composition is being described) to which the specimen can be referred, unless the clade whose composition is being described does not contain any named species or subclades.  My objective here is to avoid the use of specimens alone to describe the composition of clades larger than those approximating species.  CBM should not oppose this addition because it leaves open the citation of subclades rather than species, which is what most people would do anyway, regardless of their views about species.

Regarding my item 4 (Rec. 9c), I would like to reword the recommendation slightly to include referral of less inclusive clades as well as specimens.  It would read: In order to facilitate the referral of less inclusive clades, as well as species and specimens that are not specifiers of the clade name, the protologue should include a description, diagnosis, or list of synapomorphies.  [Proposed additions are in boldface.]

Dear CPN -

After too long of a lag, we need to come back to the 'CBM species proposal' and wrap this up.  The Cellinese et al. Systematic Biology paper is now published (Syst Biol 61(5):885-891).

When we last left this, there were only two changes that the CPN agreed to consider:

1) Broadening the definition of species
2) David M's recommended changes to Art. 21

Are these the only items that we would like to consider changing based on the 'species proposal'?  Because there has been such a long pause in this discussion, I want to give a final opportunity for the CPN to consider other categories of changes before specific wording/changes are made.

Therefore, what I would like from you is a list of general categories of changes that you would like to see incorporated (an example being the suggestion to make the definition of species more neutral/general).  General categories will be much easier to discuss rather than a list of specific proposed modifications to the wording of the PhyloCode.

Please take the time to re-familiarize yourself with the proposal and respond with any general categories of changes by Monday, September 3.

Once we agree on which points we are going to consider, we will then deal with the specific wording/additions to the PhyloCode before sharing them with the authors of the original proposal.

Thanks much and best,
Dave
