The Performance and Potential of Deep Learning for Predicting Species Distributions
Aim Species distribution models (SDMs) address the whereabouts of species and are central to ecology. Deep learning (DL) is poised to further elevate the already significant role of SDMs in ecology ...

Recent studies of species delimitation using genomic data often report poor fits of the conventional methods. Developments of new methods are required.

A Genomic Perspective on Cryptic Species Reveals Complex Evolutionary Dynamics in the Gray Zone of the Speciation Continuum
Abstract. The evolutionary dynamics of cryptic species remain poorly understood, and their detection relies primarily on methods that quantify divergence,

A new paper about DNA barcoding for "unknown" detection is now published. Detecting unknown species is generally more difficult than identifying referenced species. onlinelibrary.wiley.com/doi/10.1002/...

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....
