説明

Abstract: DNA-based species delimitation methods often predict many putative cryptic species. Interpretation of these putative species (i.e. do they represent distinct species, or is this an erroneous estimate based on DNA variability?) is challenging because estimates of DNA-based delimitation are often difficult to verify using nongenetic data such as morphology or geographical distribution. In the present study, estimates of DNA-based delimitation methods were verified based on the biological species concept in Japanese populations of Scytosiphon lomentaria. Three DNA-based species delimitation methods (Generalised Mixed Yule Coalescent, Poisson Tree Processes and Automatic Barcode Gap Discovery) were conducted using mitochondrial (cox1) and nuclear (second intron of centrin gene) DNA sequence datasets. In the S. lomentaria species complex, five putative cryptic species (Ia–Va) were well-supported by DNA-based species delimitation, and these putative species were often found in the same locality. To ve...
