CO1 Amplicon Sequence Variants of bulk arthropod samples (mild lysis) collected with Malaise traps from the Insect Biome Atlas project in Sweden

Amplicon Sequence Variants of 418bp of CO1 from mild lysed arthropod community samples collected with Malaise traps from the Insect Biome Atlas project (https://www.insectbiomeatlas.org) in Sweden, as described in the IBA data paper (https://doi.org/10.1038/s41597-025-05151-0) . This dataset was published via the SBDI ASV portal (https://asv-portal.biodiversitydata.se) , and has been updated from ‘Metadata only’ to ‘Occurrence’ type. The current version was reprocessed from Processed ASV data from the Insect Biome Atlas Project v4 (https://doi.org/10.17044/scilifelab.27202368.v4) : ASVs re-clustered with HAPP using an updated COI reference database (COIDB v5 (https://doi.org/10.17044/scilifelab.20514192.v5) ), noise removal with the NEEAT filter, and additional clean-up (https://github.com/insect-biome-atlas/utils) . Occurrence data were compiled from the following IBA Figshare items: Processed ASV data from the Insect Biome Atlas Project v4: (https://figshare.scilifelab.se/articles/dataset/Processed_ASV_data_from_the_Insect_Biome_Atlas_Project/27202368/4) - cleaned_noise_filtered_cluster_taxonomy_SE.tsv.gz (https://figshare.scilifelab.se/ndownloader/files/68649517) - cleaned_noise_filtered_cluster_counts_SE.tsv.gz (https://figshare.scilifelab.se/ndownloader/files/68649448) - spikeins_tax_SE.tsv.gz (https://figshare.scilifelab.se/ndownloader/files/68649514) - removed_control_tax_SE.tsv.gz (https://figshare.scilifelab.se/ndownloader/files/68649490) Amplicon sequence variants from the Insect Biome Atlas project v7: (https://figshare.scilifelab.se/articles/dataset/Amplicon_sequence_variants_from_the_Insect_Biome_Atlas_project/25480681/7) - CO1_asv_counts_SE.tsv.gz (https://figshare.scilifelab.se/ndownloader/files/46381132) - CO1_asv_seqs_SE.fasta.gz (https://figshare.scilifelab.se/ndownloader/files/46381138) - CO1_sequencing_metadata_SE.tsv (https://figshare.scilifelab.se/ndownloader/files/49890690) - samples_metadata_malaise_SE.tsv (https://figshare.scilifelab.se/ndownloader/files/46381114) - sites_metadata_SE.tsv (https://figshare.scilifelab.se/ndownloader/files/50735871) The following samples were excluded from this resource due to sequencing failure: P23412_1633, P23412_1638, P23412_1641, P23412_1647; or lack of non-zero counts for annotated ASVs: P20863_1580, P23412_1318, P25061_1224, P25061_1321, P25061_1440, P25061_1463, P25061_1711, P25061_1734, P25259_1250.
