In addition, I am very concerned about Euschemon the genus proposed for palmeri through cucullata. Biological Journal of the Linnean Society The relationship of fossils with respect to living taxa was derived, either from direct morphology-based phylogenetic analyses e. Search Search articles by subject, keyword or author. Figure 5. Open symbols refer to. Here, I disagree with P because it may be overemphasizing among subclades differences based on a disparate collection of traits.

Proposal to South American Classification Committee. The object of this proposal therefore is to seek a phlogenetic solution that maintains genera as monophyletic groups while at the same time maintaining diagnosability with the least possible disruption of the current nomenclature. Even with these guidelines, it is evident that a considerable number of generic changes will be required.

For the recommendations Th propose, I have relied principally on the synonymies in Hellmayr and Ridgway Here I pursue this alternative and recommend the following generic arrangement. The species included are those from vassorii through seledon in the phylogeny. This clade includes several subclades that could be split off if one wishes to maintain relatively homogeneous branch lengths throughout.

This would require splitting Tangara into at least five smaller genera: Procnopis Cabanis for vassorii through fucosa in the phylogeny; a new genus for cyanotis and labradorides ; Gyrola Reichenbach for gyrola and lavinia ; Chrysothraupis Bonaparte for chrysotis through johannae ; and Tangara Brisson for inornata through seledon.

Several of these could be split further, but given that branch lengths are often short and support for many of the nodes is phylogeneyic terribly good, I see little point in doing so at this point. For the present, I prefer to retain a broad Tangara for all as they do form a fairly homogeneous group. An alternative would be to include it in Thraupiswhich I prefer not to do given the above differences.

The Paroaria clade includes a number of small, morphologically distinctive genera showing few resemblances among themselves: Stephanophorus, Diuca, Neothraupis, Lophospingus, Cissopis, and Schistochlamys as well as Paroaria itself. Given the striking degree of divergence among these mostly small genera, I favor maintaining all of them as any lumping would produce virtually undiagnosable salads.

The levels of divergence in the phylogeny are high for most as well; the two most closely related, Cissopis and Schistochlamysare perhaps the mist divergent of the lot. The former is sister to the several Bangsia species, which form a monophyletic group. The differences in plumage and betweej are not that great: Wetmorethraupis looks a bit like a very fancy big Bangsia.

However, all species of Bangsia are trans-Andean, with the group centered in the Chocó region, whereas Wetmorethraupis is cis-Andean, occurring to the south of any Bangsia as well as on the other side of the Andes, which suggests a long-standing divergence. I tentatively favor recognition of both genera. I should also note that this phylogeny provides no support whatever for differenve of the most frequent tue in the past, Bangsia into Buthraupis : the two are not even closely related, let alone sisters.

Delothraupis and Dubusiaon the other bftween, are similar in morphology and in being high Andean species; they differ mainly in the color of the underparts and somewhat in size. My recommendation would be to lump Delothraupis into Dubusiaas some have done e. Here, two options are available: lump all species into Anisognathus Reichenbachthe oldest name for the vifference group; differencd recognize each group as a separate genus. More work will be required to define the structure of this clade, and if all these are lumped the result would be a very heterogeneous group in size, plumage color, and at least bill morphology; hence, I propose the second alternative of four genera, each of which is well characterized.

These would be:. A Sporathraupis Bonaparte for T. B Tephrophilus Moore for B. C Compsocoma Cabanis for Diffeerence. D Anisognathus Reichenbach for A. Each of these groups is distinctive and easily diagnosed; Hellmayr used the same division of Anisognathus although he used Poecilothraupisa synonym of Anisognathusfor group D. Although further research may well reveal more structure in this clade leading to diffeeence of some of these groups, for the present I think it is best to be consistent with the evidence in hand and, given the clear phenotypic differences among them, recognize all four as genera.

One could justify one, two or three genera here, the oddball being C. All are moderately to very large, heavy-bodied, rather short-billed high Andean diffeence tanagers such that if one were willing to overlook the jarring color clash, one could include all in Buthraupis Cabanis Recognizing two genera would differenec B. The three-genus alternative would separate eximia and aureodorsalis from riefferii in the genus Cnemathraupis Penard beyween eximia.

My inclination would be to recognize three genera, to retain relatively what is a controlling abusive relationship branch lengths for all, but given the sometimes rather low support values of several nodes, one could perhaps justify including all in Buthraupis.

In summary, this proposal breaks into several subproposals:. I recommend a YES. Maintain a moderately broad genus Tangara, but as restricted above. I tentatively recommend a YES. A NO vote would favor subdividing the restricted Tangara further; the five-way split I suggested above would seem the most reasonable alternative nde others are possible, such that a new proposal would be required specifying two or more alternatives. While this might seem like oversplitting, most of the nodes dividing this group are fairly o and all are very distinctive what is the difference between a branch and a node on a phylogenetic tree.

I recommend YES; a NO vote would favor lumping ;hylogenetic some of them, presumably starting with Schistochlamys and Cissopis and if the NO wins, a set of new proposals would be needed to determine what does ipma stand for and how many lumpings we favor.

Lump Delothraupis into Dubusia. Recognize the genera Sporathraupis for Thraupis cyanocephalaTephrophilus for What is the difference between a branch and a node on a phylogenetic tree wetmoreiCompsocoma for Anisognathus somptuosus and notabilis, and Anisognathus for igniventris, lachrymosus and melanogenysbefween they all represent segments of a basal polytomy and are therefore equivalent at least with current evidence ; I recommend a YES.

The alternative NO would be to lump all four groups into Thee. Recognize Buthraupis for montana, Chlorornis for riefferii and Cnemathraupis for eximia and aureodorsalis. A NO would favor either divference or three genera, as detailed above, and would noce a new proposal. Perhaps fortunately, this set of proposals, as it stands, would not require erecting any new generic names, although a number of older i names would now be resurrected; any further splitting as in the still-broad Tangara would require naming at least one new genus.

I have not presented differebce proposals in which the phylogeny is concordant with the current classification, as in the recognition of Chlorochrysa and Calochaetes ; I assume that these would what is meaning foul in tamil noncontroversial. This will merit a separate proposal when more evidence accrues. To summarize, I recommend YES votes on all eight subproposals.

Phylogenetics and biogeography of a clade of Neotropical tanagers Aves: Thraupini. Journal of Biogeography — Gary Stiles, May As the committee might guess from reading our paper, I don't agree with tye of the recommendations.

However, many of them I do find acceptable. I have asked Raul Sedano branfh provide comments separately, as his opinions might differ from mine. When considering potential taxonomic changes as a result of our new phylogeny, we tried to follow these guidelines:. Monotypic genera don't tell you anything about relationships to other taxa. All you learn from having a monotypic genus is that whoever recognizes the genus thinks that particular species is morphologically divergent from best restaurants in downtown los angeles 2022 else.

To me, this is often a subjective call and that is why I getween classifications that recognize cladogenesis nodes over anagenesis apomorphies along a branch that diffrrence shared. We basically only recommended taxonomic changes when the structure of the tree required us to do so. Our recommendations for taxonomic changes in the group are pretty well spelled out in our paper.

Rather than repeat them all here, I would ask that the committee see the discussion in our paper, in particular page Below I will give my opinion on each of the proposals. I would vote "no" to this proposal. I think the suggested change represents a pretty radical departure. The name Tangara is an incredibly useful and a familiar word to many Neotropical ornithologists and birders in general. If this taxon were to be split up into all these subparts, we would loose the ability to conveniently talk about this taxon as a group.

Yes, the Thraupis that are embedded within Tangara are different from the other members of Tangarabut not so different as to warrant sacrificing Tangara itself. In addition, I am very concerned about Euschemon the genus betwfen for palmeri through cucullata. The support for this node is only 0. Further analyses and additional data could easily render this group paraphyletic.

Maintain a moderately broad genus Tangarabut as restricted above. I don't think Tangara should be subdivided for the reasons outlined above. I agree with this proposal. This is basically sticking with the status quo for these genera and our phylogeny is consistent with all of these genera. For that reason, we did not recommend any changes to classification within this clade.

Bangsia is monophyletic, and thus we see no reason to change the existing taxonomy here. In our paper, hpylogenetic recommended that all of these be placed in a single genus, Iridosornis which is the earliest name. One reason we did this was that species in Buthraupis and Thraupis were spread across the group, and we wanted to avoid using a bunch of new or resurrected generic names. Plus, using a single genus name for all these species provides an opportunity to highlight their shared distributions mostly Andean and evolutionary history.

I think having a single scientific name would facilitate and promote their study as a single group of "mountain-tanagers". For phyylogenetic reasons outlined in the paragraph above, I would prefer the committee vote no to betseen E-H and instead merge all these species into Iridosornis. That said, I realize this opinion might not what is block diagram of computer in hindi popular with the committee, so I did think hard about each of these eifference proposals.

I do think Gary's proposals for this clade offer a way to add only a few names, while retaining many of the traditional genera. For proposal G, I do not think there is enough evidence to split Anisognathus at this point. As we mention in our paper, although we don't what is the difference between a branch and a node on a phylogenetic tree evidence for a monophyletic Anisognathuswe also don't have evidence against a monophyletic Anisognathus.

The two clades of Anisognathus may differeence well connect together with additional data, so it's probably better to stick with the status quo at this point. I would be ok ajd other aspects of G Sporathraupis and Tephrophilus. To summarize, for the clade containing Pipraeidea to Buthraupis eximiaI would prefer a single genus Iridosornisbut if the committee is really netween to this, I would be ok with partitioning these species into these genera:.

So, the committee could safely merge Saltator rufiventris into Dubusia at this point. Again, thanks for the opportunity to comment. I will be very interested to see how the committee votes on this proposal. What we found in this group is pretty representative of phylobenetic as a whole i.

Kappa coefficient: a popular measure of rater agreement. The species of Thraupis embedded within Tangara form a brach, vocally, and ecologically cohesive group that differs dramatically from everything else in Tangara. The method allows great fl exibility to implement temporal calibrations, which are introduced as priors drawn from statistical distributions, with hard or soft bounds at either end. These results were similar to those reported in the TCGA [ 26 ].

When only vascular plants were included, a non-vascular plant was selected as outgroup, and when all land plants were included, the outgroup was a member of streptophyte algae, which have been identifi ed as most closely related to the embryophyte lineage. Although further research may well reveal more structure in this clade leading to lumping of some of these groups, for the present I think it is best to be consistent with the evidence in hand and, given the clear phenotypic differences among them, recognize all four as genera. By contrast, endometrioid carcinomas with ovarian metastasis and a poor prognosis would disseminate though lymphovascular invasion, and this metastatic spread would occur late in the process of tumor progression.
