All reviews of published articles are made public. This includes manuscript files, peer review comments, author rebuttals and revised materials. Note: This was optional for articles submitted before 13 February 2023.
Peer reviewers are encouraged (but not required) to provide their names to the authors when submitting their peer review. If they agree to provide their name, then their personal profile page will reflect a public acknowledgment that they performed a review (even if the article is rejected). If the article is accepted, then reviewers who provided their name will be associated with the article itself.
I believe that you properly addressed all of the comments by the reviewer. Congratulations!
I'm glad to see that many of the suggestions by the reviewers have been addressed, but there are still a few issues (in the attached PDF) that need to be tackled before the paper is ready for submission.
There are only minor issues, concerning figure labels and some isolated suggestions along the text. Please see the annotations added to the manuscript PDF.
Both reviewers provided very thoughtful and important issues that have to be addressed before the paper is ready for publication. Pay particular attention to the relationship between the morphological variation found in your study and previous phylogenies that have been published before on the "prasinus" group.
Please also note the extensive annotated document from Reviewer 1
- There are some parts of the text that are not clear enough and must be rewritten. Besides, the author did not make explicit some relevant information. Please see the annotations added to the manuscript PDF.
- There is an issue concerning the Sections subdivision (Methods and Results are presented together). Please see this comment in the manuscript PDF.
- There are some issues with the labels of tables and figures that difficult the full understanding of what it is presented. Please see the annotations added to the manuscript PDF.
I found the paper rather too long and not easy to follow.
But what made it really hard on me was that species limits were evaluated primarily through morphometrics and that species groups were delimited only based on statistically significant differences between PCA values.
I believe that this paper adds some important knowledge on the "prasinus" group, but the morphometric data should be discussed in more direct perspective with the phylogenetic data available so far from the different papers cited. In other words, what about to contrast the significant PC pairwise value differences against genetic distances? I would be more confortable accepting purely phenetic results if I knew that they had some bearing on some tree based hypothesis of ancestry. This comparison is made throughout the paper, but it should be the main part of the results in my view.
Even if you do not contrast the morphometric data directly with one or several trees, the paper fails to provide lists of sets of discrete characters (plumage for instance) that diagnose unequivocally each different groups revealed by significant PCA value differences. In other words, is there any additional data (characters) corroborating the PCA significant differences? What are they? Do the purported hybrids between these groups vary accordingly to what is expected for the color characters? How were they considered intermediate?
In conclusion, I found this paper important because of the sheer amount of data it brings in to the subject, but it should be more concise and, if a new treatment for the complex is suggested, more detailed diagnoses should be provided as well as how they relate to already published phylogenies on the "prasinus" group.
