Macroinvertebrate-Based Biomonitoring of Coastal Wetlands in Mediterranean Chile: Testing Potential Metrics Able to Detect Anthropogenic Impacts

Round 1

Reviewer 1 Report

The manuscript entitled "Macroinvertebrate-based biomonitoring of coastal wetlands in Mediterranean Chile: testing potential metrics able to detect anthropogenic impacts" is interesting and generally well written. A method for discrimination between disturbed and non-disturbed sites would be helpful. The authors compared most of the available benthic macroinvertebrates metrics with the disturbance of the particular sites. I do not have any problems with the manuscript, the biggest pitfall of the manuscript (site macrozoobenthos evaluation from just one sampling) is commented by the authors. The significance of geometric mean body size metric is somewhat surprising - it should be discussed why this metric should correlate with site disturbance. 

Beside this, I have just two minor remarks - the reference to Table S1 should be replaced by Table S2 (l. 163); "oxigen" in Fig. 2 should be replaced by "oxygen".

Reviewer 2 Report

I enjoyed reading your paper and I think that it will be a contribution to the understanding of Chilean coastal wetlands. 

Finding that detritivore abundance responded positively to disturbance was not surprising. However, the negative response of body size to disturbance was somewhat surprising to me.  Can you attribute that response to any specific disturance?

Finally, I've enclosed a table with specific comments for your consideration.
