摘要

土壤和凤梨是巴西大西洋森林生物多样性的重要栖息地。然而,对这些环境中的单细胞真核生物和细菌的了解仍然有限。本研究利用16S和18S rRNA基因元条形码技术,比较了凤梨水缸(BWT)及其邻近土壤中单细胞真核生物、真菌、后生动物和细菌的多样性和群落结构。群落在不同生境间差异显著,但有一定的类群共享,表明生境的连通性。单细胞真核生物以纤毛虫为主,土壤中以尾虫为主。细菌群落以假单胞菌门为主,真菌组成较为均匀,各样本均以子囊菌门为优势门。后生动物群落在丰富的门之间变化,它们在BWT中的存在表明该水资源在森林内的利用。这项研究提供了这个独特生态系统中真核生物和细菌多样性的基本基线数据,突出了大西洋森林中不同的栖息地如何支持不同的群落。

Is the Composition of Communities in Bromeliad Water and Adjacent Soil Similar?

Soil and bromeliads are important habitats contributing to the biodiversity of the Atlantic Forest in Brazil. However, knowledge of unicellular eukaryotes and bacteria in these environments remains limited. This study compared the diversity and community structure of unicellular eukaryotes, fungi, metazoan, and bacteria in bromeliad water tanks (BWT) and adjacent soil using 16S and 18S rRNA gene metabarcoding. Communities differed significantly between habitats but shared some taxa, suggesting habitat connectivity. Ciliates dominated unicellular eukaryotes in BWT, while Cercozoa prevailed in soil. Bacterial communities were dominated by Pseudomonadota, while fungal composition was more uniform, with Ascomycota as the dominant phylum across samples. Metazoan communities varied among abundant phyla, and their presence in BWT suggests the use of this water resource within the forest. This study provides essential baseline data on eukaryotic and bacterial diversity in this unique ecosystem, highlighting how distinct habitats within the Atlantic Forest support different communities.
