It was a great pleasure reading this interesting and exciting work and we are extremely grateful to the authors for posting it as a preprint on bioRxiv and for their obvious commitment to open, reproducible science. In addition to most of the data used in this paper being available in a public data base, the code for the analyses is extremely well commented and available on Zenodo. Meta-analysis like this, while difficult, are absolutely necessary to illuminate larger ecological trends, and we thoroughly appreciate the effort made here. We sincerely hope that our comments are useful to the authors and we look forward to reading the final version when it is published.
