5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Review of High coral heat tolerance at local-1 scale thermal refugia.

This is an interesting, well written paper having results of likely interest to a coral reef readership. Detailed comments required to be addressed in a revised manuscript are detailed below.

I have only one main concern with the data presented in this manuscript and that is the use of coral assemblage level bleaching data to examine spatial variability in assemblage wide coral bleaching but then then species specific heat tolerance data for A. digitifera. The different taxonomic resolution of the two data sets calls into question the veracity of the main results of the paper. If possible, I suggest the analyses using coral assemblage data be run with digitate Acropora or ideally A.digitifera data only. If this is not possible the authors should provide a more significant justification of the mismatched datasets in the methods and discussion to justify their results.

Detailed comments

Line 8. Change vary to varies.

Line 77. Additional non-thermal environmental variables could be discussed here, for example turbidity (Sully and Van Woesik (2020)), water flow (Page et al (2023) High survival following bleaching underscores the resilience of a frequently disturbed region of the Great Barrier Reef) is this discussion of the effect of environmental variables on bleaching.

Line 99 “From a management perspective, it is desirable if heterogeneity in recent (i.e., in the satellite record) past exposure of reefs to marine heatwave stress leads to predictable differences in coral population responses across seascapes, as this could allow managers to prioritise interventions in locations where they are likely to be most effective”. This statement would be strengthened if it also referred to those studies of winners and losers after bleaching in different regions or changes over time in bleaching winners and losers e.g. van Woesik et al. Revisiting the winners and the losers a decade after coral bleaching and McClanahan (2020) Highly variable taxa-specific coral bleaching responses to thermal stresses.

Line 173. DHW is an acronym frequently used in the coral reef literature. I suggest you replace DHW with mDHW or some other variant of DHW to avoid confusion. Please change throughout the manuscript.

Line 188. Please define SD before using this acronym.

Line 204. Given that the heat stress experiment is performed on A.digitifera, I was surprised to see the assemblage wide coral data provided as apposed to data on A.digitifera only bleaching severity. Please justify the use of the two different data sets.

Line 215. It would be more useful to here use bleaching in A.digitifera or at least digitate Acropora only colonies, rather than all hard coral taxa, given the high variability in coral taxa susceptibilities to bleaching. Please justify the use of all coral taxa here, rather than the target A.digitifera. Ideally this analysis should be replaced with the species specific or life-form specific data and analysis, otherwise justification of this exclusion should be included in the manuscript.

Line 268. Please include estimate of nubbin average size.

Line 284. Write MMM acronym in full and define on its first usage.

Line 293. I am curious as to why no ramping in light was used in this experiment to replicate sunrise and sunset? Please include rationale in manuscript.

Line 213. Change N to a lower case n throughout the manuscript.

Line 727. Potential tradeoffs between heat tolerance and reproduction could also be mentioned here, with the inclusion of relevant references.

358. Please provide more explanation of the ‘flexible’ threshold parametrisation and justification of this approach.

Line 360. Please provide a description of how colonies were chosen for this element of the project. Chosen at random from a set area of reef? This is needed to justify the result at line 530.

Line 586. The use of life-form or species level data would have negated this speculation. Please consider the use of life-form or species level data for this analysis as suggested above. Without this level of data is it difficult to ascertain that site level differences in beaching don’t just reflect difference sin communities at these sites. The justification “given widespread temporal stability of Acropora populations (Gouezo et al., 2019).”: is insufficient and a more detailed justification should be proposed or species level data used instead.

Line 631. Provide a more recent reference if possible to demonstrate higher heat tolerance of Durusdinium.

Additional Editor Comments (if provided):

Reviewer #1

I believe the authors have provided a very thorough response to my reviews and I now find the manuscript suitable for publication.

Reviewer #2

Global warming is big challenge that human faces. The study of tolerance of corals to heat is thus of great significance. The manuscript entitled “High coral heat tolerance at local-scale thermal refugia” by Lachs et al. analyzed coral responses to 36 years of satellite-derived cumulative heat stress. It was found that corals located at local-scale hotspots are not necessarily more heat tolerant than those at nearby thermal refugia. This is a good case study, which provides key scientific basis for environmental management and decision-makers. Though I am not the original reviewer, I quite enjoy reading it. The paper is well designed, and has a clear logic. It is well written, and I suggest publication of this work. I have only several minor comments, see follows.

Abstract: The Republic of Palau could be better than Palau.

Author affiliations are usually provided after the name list, and before abstract. I do not think this is a big problem, but it looks strange.

The unit for Degree Heating Weeks is “°C-weeks”, which is not a commonly used unit. It is well known in the community of people who studies heat stress, but researches in other areas who also concern climate change may not be very familiar with it. I suggest the authors explain it. For example, “a unit combining intensity and duration of heat stress”?

Can the authors give a scale bar in Fig. 1c or 1e?

A section of conclusion may not be mandatory for PLOS Climate, but it may be helpful for readers to obtain the key ideas rapidly. I suggest the authors consider this in their future research.

For Data and code availability, the authors mentioned all data and code will be available at a https://figshare.com/s/faac387cb999778055cc, but the link is still unavailable. Please check it.

Line 845: eLife, rather than Elife.
