Data from "Aquatic and terrestrial environmental DNA signals reveal decoupling of blue-green communities along an urbanization gradient". -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Urban_BGB_OTU.csv - OTU table. Rows = sites, columns = genus. Values indicate number of reads per OTU (after filtering, contamination removal, and rarefaction). Urban_BGB_taxo.csv - Taxonomy of all retained OTUs. Urban_BGB_covariates.csv - All covariate values extracted for all sites. As many sites are private, their location cannot be disclosed publically. Urban_BGB_life_history.csv - Life history (i.e., terrestrial, aquatic, or semi-terrestrial/semi-aquatic life cycle) for all shared OTUs. metabarcoding_metadata.csv - metadata to process the raw sequences. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Raw sequences are available on the European Nucleotide Archive under accession project number PRJEB88517.
