Despite several efforts to quantify the effectiveness of forest certification in developing sustainable use of forest resources, there is little evidence that certified forests are more effective in conserving fauna than non‐certified managed forest. To evaluate the impact of forest certification on the fauna, we compared the biodiversity in reference sites (n = 23), Forest Stewardship Council (FSC) certified management sites (n = 24) and non‐FSC management sites (n = 20) in the Tahuamanu region of Peru, during the dry season of 2017. Specifically, we determined if the acoustic space used (ASU), soundscapes composition, and the bird richness and composition significantly varied among the three management types. Variation in ASU was best explained by management type and mean ASU in the FSC sites was significantly greater than the reference and non‐FSC sites, possibly suggesting greater richness of acoustically active species. An ordination analysis of the soundscapes showed that there was a significant difference among the three management types. There was greater dissimilarity in soundscape composition between the FSC and non‐FSC sites, and greater overlap between FSC and reference sites. Bird identifications resulted in 11,300 detections of 226 bird species. Bird species richness and composition were not significantly different among the management types, indicating, in this context, that birds may not be the best indicators of different management strategies. The weak discrimination by the bird community is likely due to their dispersal ability, undisturbed primary forest matrix, and the occurrence of bamboo patches. The differences in ASU among the management types were most likely due to differences in acoustically active insects, which may be more sensitive to changes in microhabitat differences. Our findings correspond with the conclusions of other studies that certified forests can maintain levels of fauna biodiversity similar to those of undisturbed primary forest in the Amazon region.

FSC森林认证如何影响秘鲁Madre de Dios的声音活跃动物区系？

尽管在量化森林认证在开发可持续利用森林资源方面的有效性方面做出了许多努力，但几乎没有证据表明认证森林在保护动物方面比未认证经营森林更有效。为了评估森林认证对动物的影响，我们比较了参考地点（n = 23），森林管理委员会（FSC）认证的管理地点（n = 24）和非FSC管理地点（n = 20）在秘鲁的Tahuamanu地区，在2017年的旱季期间。具体而言，我们确定了三种管理类型中使用的声学空间（ASU），声景成分以及鸟类的丰富度和成分是否存在显着差异。ASU的变化最好用管理类型来解释，FSC站点中的平均ASU显着大于参考站点和非FSC站点，这可能表明声音活跃物种的丰富度更高。对音景的排序分析表明，三种管理类型之间存在显着差异。FSC和非FSC站点之间的音景组成差异更大，FSC与参考站点之间的重叠更大。鸟类识别结果导致对226种鸟类进行了11300次检测。在不同的管理方式中，鸟类的物种丰富度和组成没有显着差异，这表明在这种情况下，鸟类可能不是不同管理策略的最佳指标。鸟类群落的分辨力很弱，可能是由于它们的扩散能力，未受干扰的原始森林基质以及竹片的出现。在管理类型之间，ASU的差异很可能是由于声活跃昆虫的差异引起的，这种昆虫对微生境差异的变化更敏感。我们的发现与其他研究得出的结论一致，即经过认证的森林可以维持与亚马逊地区未受干扰的原始森林相似的动物多样性水平。鸟类可能不是不同管理策略的最佳指标。鸟类群落的分辨力很弱，可能是由于它们的扩散能力，未受干扰的原始森林基质以及竹片的出现。在管理类型之间，ASU的差异很可能是由于声活跃昆虫的差异引起的，这种昆虫对微生境差异的变化更敏感。我们的发现与其他研究得出的结论一致，即经过认证的森林可以维持与亚马逊地区未受干扰的原始森林相似的动物多样性水平。鸟类可能不是不同管理策略的最佳指标。鸟类群落的分辨力很弱，可能是由于它们的扩散能力，未受干扰的原始森林基质和竹片的出现。在管理类型之间，ASU的差异很可能是由于声活跃昆虫的差异引起的，这种昆虫对微生境差异的变化更敏感。我们的发现与其他研究得出的结论一致，即经过认证的森林可以维持与亚马逊地区未受干扰的原始森林相似的动物生物多样性水平。在管理类型之间，ASU的差异很可能是由于声活跃昆虫的差异引起的，这种昆虫对微生境差异的变化更敏感。我们的发现与其他研究得出的结论一致，即经过认证的森林可以维持与亚马逊地区未受干扰的原始森林相似的动物生物多样性水平。在管理类型之间，ASU的差异很可能是由于声活跃昆虫的差异引起的，这种昆虫对微生境差异的变化更敏感。我们的发现与其他研究得出的结论一致，即经过认证的森林可以维持与亚马逊地区未受干扰的原始森林相似的动物生物多样性水平。
