Abstract:
:Rainforest aquatic ecosystems include complex habitats with scarce information on their unicellular eukaryote diversity and community structure. We have investigated the diversity of ciliates in freshwater and brackish environments along the Brazilian Atlantic Forest, based on the hypervariable V4 region of the 18S-rDNA obtained by high-throughput DNA sequencing. Our analyses detected 409 ciliate taxonomic units (OTUs), mostly attributed to the classes Oligohymenophorea and Spirotrichea. A total of 11 classes, 12 subclasses, 112 genera, and 144 species were reported. We found the following: (a) the ciliate communities are more diverse in freshwater- than in Atlantic Forest-associated brackish environments; (b) the ciliate communities are composed by a small amount of highly abundant OTUs, but a high number of low-abundant or rare OTUs; (c) nearly one-third of the ciliate OTUs share less than 97% sequence identity to reference sequences and (d) phylogenetic inference supports the hypothesis that the V4 region of the Ciliophora 18S-rDNA is a suitable marker for accurate evolutionary inferences at class level. Our results showed that a considerable fraction of the HTS-detected diversity of ciliates from Brazilian Atlantic Forest is not represented in the currently available molecular databases.
