Welcome to Worldmap of Fish Genetic Diversity (WFGD)

The app is designed to visualize biogeographic patterns of fish genetic diversity. So, we mined the Barcode Of Life database to extract mitochondrial barcode sequences of Cytochrome Oxidase Subunit 1 (COI) from marine and freshwater actinopterygii species.

Genetic diversity was estimated as the mean number of mutations per base pair for COI sequence across species within each cell on a worldwide grid with a 200-km spatial resolution.

• 514 cells for marine fishes
• 343 cells for freshwater fishes

The colour gradient represents the relative variation of intraspecific genetic diversity: the reddest square cells have the highest genetic diversity.
