Figure 3 in Calling phenology of anurans in a tropical rainforest in South Mexico: testing predictive models

Figure 3. Rose-diagram of anuran assemblage relative calling intensity. The length and colour (light = low, dark = high) of the bars from the centre indicate the intensity of vocalisation for the temporal section. A Rayleigh z test for unimodal orientation was performed, resulting in significant evidence of non-uniform distribution of vocalisations across the year (P = 0.0303).
