Please publish the revised paper.

This paper by Tilman et al has been reviewed by two referees, one of which is very positive and recommends publication after relatively minor changes; the other referee is much more critical and demands major changes. The authors responded positively to both reviewers’ comments. In the case of referee 2 often with robust replies, stating their reasons for their text quite firmly. In spite of this, the authors have taken the critical comments of reviewer 2 very seriously and the paper has been revised extensively. I recommend publication without recourse to further referees based mostly on the positive views expressed by reviewer 1.
