A Framework for Species Discovery and Identification

The Barcode Index Number (BIN) system clusters DNA barcode sequences into operational taxonomic units that often correspond to species. Each BIN is automatically generated, uniquely identified, and linked to metadata, including taxonomy, specimen images, and collection details. BINs provide a standardized framework for species identification and discovery, aiding in the study of biodiversity. This system enhances taxonomic resolution, facilitates comparisons across datasets, and supports the discovery of new species by highlighting sequences that do not match known taxa.

01

DNA Sequencing:

DNA sequences are obtained from specimens and submitted to BOLD, the Barcode of Life Data System.

02

Sequence Clustering

Similar sequences are grouped into clusters, each representing a unique BIN. These clusters often correspond to a single species or distinct genetic lineage.

03

BIN Assignment

Each cluster is assigned a unique BIN, which serves as a digital identifier for the genetic group.

04

Species Identification:

BINs provide a standardized framework for species identification and discovery, facilitating global biodiversity research and monitoring.

What are BINs?

Barcode Index Numbers (BINs) are unique identifiers for clusters of DNA barcode sequences that often correspond to species. Generated automatically by BOLD, each BIN links sequences to rich metadata, such as taxonomy, specimen images, and collection details.

Why use BINs?

The BIN system enhances species identification and discovery, supports taxonomic research, and allows for effective comparison of genetic data across diverse datasets. It serves as a critical tool in biodiversity studies, highlighting both known and potentially new species.
