A Bibliometric Analysis of Indonesia Biodiversity Identification through DNA Barcoding Research from 2004-2021

Abstract

Abstract Indonesia is well-known for having a vast and rich endowment of unique and genetically diverse biodiversity resources. Currently, initiatives are taking place around the world to generate DNA barcode libraries to make these data available to better understand biodiversity. The objectives of this study are to document DNA barcode research trends and detect the extent to which its application has evolved in Indonesia. The analysis was investigated using a compilation of 446 published papers, obtained from Harzing's Publish or Perish 8. The number of DNA barcode publication records has increased by a geometric average of 15.4/year. The number of studies involving molecular identification (30.1%), species and genetic diversity (10%), and evolutionary or phylogenetic studies (10%) appears to have driven much of the publication activity. The top three taxa studied include fishes (32.7%), plants (24.8%), and invertebrates (12.5%; except insects). We discovered that using a single molecular marker is still dominant (62.8%). We conclude that the practices of DNA barcoding data are likely to become a valuable resource in many sectors and focuses. However, the number of Indonesian DNA barcode records in public databases is relatively lower than in other mega biodiversity countries. The establishment of DNA barcoding initiatives and a national DNA barcode reference library in Indonesia would promote DNA barcoding applications to help conserve Indonesia biodiversity.
