Dear Editor

Thank you for the invitation to revise this nice manuscript.
The manuscript is well-written and very readable. I just pointed out some parts that need better clarification, mainly the hypothesis and some parts of the Discussion.

Page 6, lines 52-54: You did not explain interaction beta diversity yet. It is better to move this sentence to the paragraph where you explain interaction beta diversity.

Page 6, lines 58-61: Please insert a sentence explaining how Island Biogeography theory can be applied to the studies of habitat fragmentation involving multiple trophic interactions.

Page 6, lines 73-75: But can propagate more indirect effects throughout the network. See Pires, M. M., O'Donnell, J. L., Burkle, L. A., Díaz-Castelazo, C., Hembry, D. H., Yeakel, J. D., ... & Guimarães Jr, P. R. (2020). The indirect paths to cascading effects of extinctions in mutualistic networks. Ecology, 101(7), e03080-e03080.

Page 6, lines 82-85: How habitat fragmentation can result in species turnover in plant-aphid network? Is turnover among plants or aphids or both? Cite an example.

Page 6, lines 95-101: What are the expectations about these objectives?

Introduction: How network specialization can be linked with turnover and rewiring?

Page 8, line 116: Include the author of Pinus massoniana description.

Page 8, line 120: .. island area (0.08–128.04 ha) and...is it minimum and maximum areas? Please specify.

Page 10, line 154: Which GLM family did you use in the analysis? Please specify.

Page 11, line 177: Did you use a weighted or binary network for interaction beta diversity?

Page 15, lines 274-279: Does the rH2 is different from the empiric H2 of sampled communities? It can be nice to show if there are differences from the null model.

Page 15, line 283: ... our study examined the effects of habitat fragmentation on
network specialization. Please include: .. of habitat fragmentation (i.e., island area and isolation)

Page 19, lines 365-366: Interaction rewiring can result from differences in prey availability. See Ceron, K., Provete, D. B., Pires, M. M., Araujo, A. C., Blüthgen, N., & Santana, D. J. (2022). Differences in prey availability across space and time lead to interaction rewiring and reshape a predator–prey metaweb. Ecology, 103(8), e3716.

Page 19, line 366: Remove the citation in the text.

Page 19, lines 371-373: Does interaction rewiring cause the loss of interactions? This sentence needs clarification.
