DNA sequence analysis has been of the utmost importance to delimit species boundaries in the genus Diaporthe. However, the common practice of combining multiple genes, without applying the genealogical concordance criterion has complicated the robust...
Widespread species may exhibit considerable genetic variation among populations due to their extensive distribution ranges, and may even give rise to new species in remote areas. Integrative species delimitation via multiple types can provide a robus...
Liolaemus species are the only lizards inhabiting the cold and hypoxic environments of the high Andean plateau. However, delimiting species within the Liolaemus montanus group across this region remains exceptionally challenging. Two taxonomically di...
Flavonoids and other phenolic constituents are a large group of plant metabolites that have long attracted interest from researchers worldwide due to their functions in plant physiology, as well as their huge number of benefits for human health and w...
The genus Sambucus belongs to the family Viburnaceae, and has long been a debatable taxon regarding its systematics and taxonomic assignment. It is known for its morphological and genetic variations and thus the taxonomic delimitation remains uncerta...
Over the past decades, numerous studies have attempted to capture the heterogeneity of rural areas from different perspectives. Meanwhile, rural areas have undergone various changes, primarily due to urban pressure. Rejecting a dichotomous approach,...
To date, a rather large set of both mathematical theories for species delimitation, based on single-locus genetic data, and their implementations as software products, has been accumulated. Comparison of the efficiencies of different delineation meth...
Species delimitation in herbaceous bamboos has been complex and, in some genera, a great part of its diversity has been confirmed only based on genetic information, as is the case of the genus Raddia. It includes nine species, all occurring in Brazil...
To test the performance of COI-based DNA barcoding in species delimitation, we amplified and sequenced the mitochondrial COI gene from six Schizothoracine fishes endemic to Xinjiang, China. We then characterized the COI gene dataset, quantified genet...
Dipylidium caninum (Linnaeus, 1758) is a common zoonotic cestode of dogs and cats worldwide. Previous studies have demonstrated the existence of largely host-associated canine and feline genotypes based on infection studies, differences at the 28S rD...
The genetic variation in the COI gene has had a great effect on the final results of species delimitation studies. However, little research has comprehensively investigated the genetic divergence in COI among Insecta. The fast-growing COI data in BOL...
Despite extensive research into green microalgae belonging to the genus Chloroidium, their species diversity and biotechnological potential remain poorly characterized. The strain VKM Al-418, the subject of this study, was isolated from the soil of D...
The cosmopolitan nematode Spirinia parasitifera has long been considered a single, morphologically variable species; however, mounting molecular evidence suggests that it represents a complex of cryptic taxa. In this study, we describe Spirinia korea...
Limpets are marine gastropod molluscs well adapted to intertidal rocky environments, yet their taxonomic resolution remains challenging due to extensive morphological convergence and the presence of cryptic species. In this study, we applied an integ...
Larks constitute an avian family of exceptional cryptic diversity and striking examples of convergent evolution. Therefore, traditional morphology-based taxonomy has recurrently failed to reflect evolutionary relationships. While taxonomy ideally sho...
To date, five species of reddish-brown Neotriplax have been described, but their highly similar body color and other phenotypic traits make accurate taxonomy challenging. To clarify species-level taxonomy and validate potential new species, the cytoc...
