Dear Dr. Fontanini,

I have read the answers you have provided to the two reviewers that have evaluated your work. Based on that, I invite you to submit a revised version of your manuscript taking into account all the modifications mentioned in your answers to reviewers. In particular, one of the two reviewers stresses that the impact of lifestyle on the response of the different organisms is not really assessed although explicitly mentioned in the abstract. Please clarify what you mean by “lifestyle” and where it is addressed. As concerns the definition of the respiration index, one of the reviewers asks more details. On a mathematical point of view the equation is well defined but I guess that a few words explaining why this RI, a ratio of partial pressures, can be linked to aerobic stress would be helpful for a reader not expert in the field.

You manuscript will be sent for a second round of review.

Thank you so much for your efforts,
Kind regards,

Marilaure Grégoire, Associate editor.
