2.1 Data collection
We systematically reviewed the studies related to copepod associated
bacteriobiome. The relevant published research articles were searched
and retrieved from PubMed, Google Scholar and SCOPUS using keywords such
as copepods gut microbiome, copepod associated bacteria/microbiome,
copepods gut flora, copepod microbiome and zooplankton associated
microbiome on Jan 30th, 2020. Apart from the search for the published
research articles, we also searched in public databases (for published
Ion Torrent, Pyro, and Illumina sequence data) such as the NCBI-SRA,
ENA, DDBJ and Figshare using the above-mentioned keywords.
Overall, 11 study data were retrieved for meta-analysis (Table 1)
containing 514 next-generation sequence libraries. We have pre-processed
separately every individual file within the study and prepared the
quality control (QC) report.
