Processed 12S fish eDNA sequences

This dataset contains fish eDNA sequences from the 12S mitochondrial gene. eDNA has been collected in 100 stations, 25 sites, in 5 tropical marine regions. Data collection was performed between 2017 and 2020. Raw sequences have been processed through a bioinformatic pipeline, merged, demultiplexed, dereplicated, clustered as OTUs (operational taxonomic units) and assigned to a taxa. The codes to analyse the data can be found at : https://github.com/virginiemarques/Global_eDNA. The data are used to study the patterns of tropical fish distributions across spatial scales, using two different methodologies, eDNA and visual census.
