| dc.description | Despite increasing threats to the marine environment, only a fraction of the biodiversity of the oceans has
been described, owing in part to the widespread occurrence of cryptic species. DNA-based barcoding
through screening of an orthologous reference gene has been proposed as a powerful tool to uncover
biological diversity in the face of dwindling taxonomic expertise and the limitations of traditional species
identification. Although DNA barcoding should be particularly useful in the sea, given the prevalence of
marine cryptic species, the link between taxa identified through DNA barcodes and reproductively isolated
taxa (biological species) has rarely been explicitly tested. Here, we use an integrated framework comparing
breeding compatibility, morphology and mitochondrial (cytochrome c oxidase 1) and nuclear (elongation
factor-1-alpha) DNA sequence variation among globally distributed samples of the cosmopolitan marine
bryozoan Celleporella hyalina (L.). Our results reveal that C. hyalina comprises numerous deep, mostly
allopatric, genetic lineages that are reproductively isolated, yet share very similar morphology, indicating
rampant cryptic speciation. The close correspondence between genetic lineages and reproductively isolated taxa in the context of minimal morphological change suggests that DNA barcoding will play a
leading role in uncovering the hidden biodiversity of the oceans and that the sole use of morphologically
based taxonomy would grossly underestimate the number of marine species. | |
