Correction to: The ISME Journal (2014) 8, 249–256; doi:10.1038/ismej.2013.175; published online 24 October 2013

Since the online publication of this article, the authors have identified an error concerning Figure 2, namely that the incorrect figure was displayed.

The correct figure is shown here.

Figure 2
figure 1

Intensity of antibiotic inhibition (mean zone size) among all inhibitory isolate pairs from the same (sympatric, n=118 interactions) and different (allopatric, n=667 interactions) locations. Mean zone size differed significantly among sympatric vs allopatric isolate pairs (P<0.0001, Welch two-sample t-test).

This error has now been rectified, and the corrected article appears in this issue. The html and online pdf versions have also been rectified, and now carry the correct paper.

The authors would like to apologise for any inconvenience this may have caused.
