Figure 4 in Directional orientation of migration in an aseasonal explosive-breeding toad from Brazil

Figure 4. Circular histograms showing the frequency and mean vector for the directional orientation of pre- and post-reproductive migration in Melanophrŋniscus cambaraensis, excluding pseudoreplicate captures. The observed data were significantly different from expected under a uniform distribution for both pre- and post-reproductive migration, regardless of gender (Rao's spacing test, all P <0.001).
