Reviewer 1
This review paper presents new data on the state of knowledge regarding non-indigenous Cladocera species and their invasiveness potential around the word based on a large factual material. This data makes a significant contribution to the study biogeography of invasive Cladocera. The article is well written and easy to read. I think that overall this paper is an important and valuable contribution in study of the distribution and invasive potential of alien species of cladocerans. Minor modifications suggested.
*** Thank You very much!
Materials and Methods: Literature study
In my opinion, in the Appendix A should indicate which data were confirmed by molecular data and which were not.
*** OK. Positive cases are discussed.
Conclusions
In my opinion, in Сonclusion, in the section on future research, it should be pointed that the study of biodiversity, biogeography and phylogeny cladocerans should be based on molecular genetic approach.
*** Two phrase are added.
- 703, p. 27 - Delete the literature (duplicated).

Reviewer 2 Report
This is a useful and well-referenced review of an interesting and timely topic. The field of invasion biology has accelerated in recent decades. This includes the Cladocera that form a critical energy and nutrient linkage in lentic food webs. A recent explosion of anthropogenic-related dispersal vectors, funding to study the issues, and new genetic tools to evaluate the new and old morphological evidence have created an exciting yet tumultuous time in the science of reconstructing patterns of ‘global faunal mixing’ among the Cladocera as described in the title.
I thought that this review was well balanced between information and analysis, and that it raised many interesting issues regarding what we know and what we do not know on the topic.
I have only a small list of items to suggest here.
1. Figure 1. The arrow in the upper right pointing from Russia to the USA seems unnecessary, or give it a number.
2. The last line of the caption for Fig. 1 should read: Numbers correspond to the subsections in Section 3.
3. Line 62: change ‘expand’ to ‘expanded’
4. Line 91: change ‘result of’ to ‘be the result of’
5. Line 191. The published evidence suggests that Bythotrephes was first detected in Lake Ontario in 1982, not 1986. See: Johannsson, O.E., Mills, E.L. & O'Gorman, R. (1991) Changes in the nearshore and offshore zooplankton communities in Lake Ontario: 1981- 88. Canadian Journal of Fisheries and Aquatic Sciences 48: 1546-1557. It’s probably best to use the word ‘detected’ and not ‘introduced’ in that sentence.
6. Line 524: change ‘revealing’ to ‘reveal’
7. Line 557: change ‘problematic’ to ‘problem’
8. Line 577: add the word ‘in’ before ‘Cladocera’
9. Line 624: change ‘that’ to ‘than’

*** We are very grateful for the work with the manuscript!
- Figure 1. The arrow in the upper right pointing from Russia to the USA seems unnecessary, or give it a number.
*** The number is provided
- The last line of the caption for Fig. 1 should read: Numbers correspond to the subsections in Section 3.
*** Fixed
- Line 62: change ‘expand’ to ‘expanded’
*** OK. Changed to "have expanded"
- Line 91: change ‘result of’ to ‘be the result of’
*** OK. Changed

*** OK. Reference is added, the word is changed. The reference is added also to Table 1
