Correction: Effects of traffic noise on the calling behavior of two Neotropical hylid frogs.

[This corrects the article DOI: 10.1371/journal.pone.0183342.].

The images in Fig 1 are incorrectly switched. The image that appears as A should be labeled as B, and the image that appears as B should be labeled as A. The authors have provided a corrected version below.

There is an error in the caption for Fig 4, “Effects of traffic noise on call parameters of the two hylids.” Where it is written “(±SD)”, it should read “(±SE)”. Please see the corrected Fig 4 caption here.

Fig 4

Effects of traffic noise on call parameters of the two hylids.

Graphs show call parameter means (±SE) at the four periods of time inside a playback, P1 (pre–stimuli, silence), N1 (noise1), N2 (noise2), P2 (post–stimuli, silence). Dashed line represents the playback order N1 (75dB) followed by N2 (65dB) and solid line the other way around N1 (65dB) and N2 (75dB). During road noise treatments, Boana bischoffi decreased call rate (A). Peak frequency was significantly different for B. bischoffi, decreasing from period P1 to P2 (C). Call duration showed changes in B. leptolineata depending on the order of the treatment (E). Letters “a” and “–b” indicate statistically different values due to treatments (intensity) or playback periods, and “*” indicate differences due to playback type/order (65 or 75dB first).
