A new preprint about unknown detection for DNA barcoding. Unknown species are sometimes overlooked when you use short fragments.

Performance and limitations of out-of-distribution detection for insect DNA (meta)barcoding
Successful applications of DNA barcoding/metabarcoding rely on the accurate taxonomic identification of sequence fragments. When biological surveys with DNA (meta)barcoding target underexplored biolog...

Scaling Up Species Delimitation From DNA Barcodes to Whole Organelle Genomes: Strong Evidence for Discordance Among Genes and Methods for the Red Alga Dasyclonium
Molecular sequence data have become a ubiquitous tool for delimiting species and are particularly important in organisms where morphological traits are not informative about species boundaries. A ran....

Open-Set Recognition of Novel Species in Biodiversity Monitoring
Machine learning is increasingly being applied to facilitate long-term, large-scale biodiversity monitoring. With most species on Earth still undiscovered or poorly documented, species-recognition mod...
