Phytotelmata are habitats that house several species. Oftentimes invertebrate species need to disperse themselves sometimes carried by other animals, an interaction called phoresy. Phoresy can be influenced by different factors, therefore, we aim to investigate which factors influence the phoretic potential between anurans and invertebrates from bromeliads in semideciduous Atlantic Forest, as well as whether there is specificity of invertebrates with any anuran species. We tested if (a) phoresy is more common under conditions with higher rainfall; (b) there are some species of anurans that influence the phoresy of invertebrates more than others; (c) size is an important factor to phoresy. The study was developed during six campaigns in two sites containing the bromeliad Aechmea leptantha . In each campaign, water of bromeliads was collected and all anurans found in bromeliads were processed by washing the skin to collect adhered invertebrates. We recorded the prevalence, average intensity and average abundance of invertebrates between anuran species. We verified the similarity of invertebrates between anuran taxa and we tested the hypothesis of independence between them. In order to identify which factors affect phoresy, we performed a GAMLSS analysis. Invertebrates were present on 54.4% of anurans distributed in five species: Dendropsophus decipiens , Scinax pachycrus , S. x-signatus , S. auratus and Pristimantis ramagii . The estimated densities for prevalence, average intensity and average abundance of invertebrates showed distinct shapes among the anuran species, of which not all participate in the same way in invertebrate transport. The mean phoretic potential showed a significant relationship with anuran length and rainfall.

无脊椎动物在水箱凤梨科植物中辅助潜行：种间关系

Phytotelmata 是容纳多种物种的栖息地。通常，无脊椎动物物种有时需要分散自己，有时会被其他动物携带，这种相互作用称为 phoresy。泳动会受到不同因素的影响，因此，我们的目标是调查哪些因素会影响大西洋半落叶林中无脊椎动物与凤梨科无脊椎动物之间的泳动潜力，以及无脊椎动物与任何无脊椎动物是否存在特异性。我们测试了 (a) 在降雨量较高的条件下是否更常见；(b) 有一些无脊椎动物比其他种类更能影响无脊椎动物的运动；(c) 大小是影响 phoresy 的一个重要因素。该研究是在包含凤梨 Aechmea leptantha 的两个地点的六次活动中进行的。在每个广告系列中，收集凤梨科植物的水，并通过清洗皮肤来处理凤梨科植物中发现的所有无尾类，以收集粘附的无脊椎动物。我们记录了无脊椎动物物种之间无脊椎动物的流行率、平均强度和平均丰度。我们验证了无脊椎动物类群之间无脊椎动物的相似性，并测试了它们之间独立性的假设。为了确定影响泳姿的因素，我们进行了 GAMLSS 分析。无脊椎动物存在于 54.4% 的无脊椎动物中，分布在五种物种中：Dendropsophus decipiens、Scinax pachycrus、S. x-signatus、S. auratus 和 Pristimantis ramagii。无脊椎动物的流行率、平均强度和平均丰度的估计密度在无脊椎动物物种之间显示出不同的形状，其中并非所有物种都以相同的方式参与无脊椎动物的运输。
