Lunar phases remarkably influence the circadian cycle of living beings. Early amphibian studies date back to the 1960s, but only recently has more research been conducted in this field. Much still needs to be understood to establish the behavioral pattern of this group according to the synodic cycle. In the present study, we sought to determine (i) whether the vocalization activity was influenced by the lunar phases and (ii) whether the influence was species-specific or affects the community with equal intensity. We expected a great diversity of behaviors and adaptations. Rayleigh's test was used to verify whether the sample differs significantly from the null hypothesis; Rao's test was used to check sample size sufficiency; and the Kiviat diagram was used to evaluate the activity of the species in relation to the complete synodic cycle. We have observed 1691 individuals of 37 species over 882 d. The lunar cycle influenced 78 % of the species, with 32 % preferring the lower-albedo phases. The activity pattern of each species was established. These results suggest that the lunar phases influence the vocalization activity of most species. Therefore, there is a general pattern of activity related to the synodic cycles; however, the specificities still need to be better understood.

青蛙发声受月相的影响：巴西青蛙倾向于偏低反照率的相

月相显着影响生物的昼夜周期。早期的两栖动物研究可以追溯到1960年代，但是直到最近才在该领域进行了更多的研究。根据宗教法则周期，要建立这一群体的行为模式，仍然需要很多理解。在本研究中，我们试图确定（i）发声活动是否受到月相的影响，以及（ii）这种影响是否是特定于物种的，或者是否以相等的强度影响到社区。我们期望行为和适应的多样性。瑞利检验用于验证样本是否与原假设存在显着差异。Rao检验用于检查样本大小是否足够。Kiviat图用于评估物种与整个宗教会议周期有关的活动。我们已经观察到882 d内共有37种1691个个体。月球周期影响了78％的物种，其中32％的人喜欢较低的反照率相。建立了每个物种的活动模式。这些结果表明，月相影响大多数物种的发声活动。因此，存在一种与宗教会议周期有关的一般活动模式。但是，仍需要更好地了解其特异性。
