Abstract:
DNA barcode datasets are a useful tool for conservation and aid in taxonomic identification, particularly in megadiverse tropical countries seeking to document and describe its biota, which is dropping at an alarming rate during recent decades. Here we report the barcodes for several low elevation bird species from northern Colombia with the goal to provide tools for species identification in this region of South America. We blood-sampled birds in a lowland tropical forest with various degrees of intervention using standard 3 × 12 m mist-nets. We extracted DNA and sequenced the COI barcode gen

Abstract:
MtDNA COI barcodes have frequently been used in identification to associate an unknown life stage in insects with a known species. This study reports the discovery of hoverfly larvae in the fungal fruit bodies of <i>Rhizopogon luteolus</i> Fr. &amp; Nordholm, 1817 in Finland. The identity of the larvae was firstly resolved using mtDNA COI barcodes generated from the larvae and tree-based identification confirming the species Pelecocera (Pelecocera) tricincta Meigen, 1822 and Pelecocera (Chamaesyrphus) caledonica (Collin, 1940) (Diptera, Syrphidae). Obtained pupae were reared into adult flies a

Abstract:
Large-scale sequencing of short mtDNA fragments for biodiversity inventories (‘DNA barcoding’) indicates that sequence variation in animal mtDNA is highly structured and partitioned into discrete genetic clusters that correspond broadly to species-level entities. Here we explore how the migration rate, an important demographic parameter that is directly related to population isolation, might affect variation in the strength of mtDNA clustering among taxa. Patterns of mtDNA variation were investigated in two groups of beetles that both contain lineages occupying habitats predicted to select for

We sequenced 665bp of the Cytochrome C Oxidase I (COI) barcoding marker for 257 specimens and 482bp of Elongation Factor 1-α (EF1-α) for 237 specimens belonging to the leafmining subgenus Ectoedemia (Ectoedemia) in the basal Lepidopteran family Nepticulidae. The dataset includes 45 out of 48 West Palearctic Ectoedemia s. str. species and several species from Africa, North America and Asia. Both COI and EF1-α proved reliable as an alternative to conventional species identification for the majority of species and the combination of both markers can aid in species validation.

Abstract:
Freshwater fish stocks worldwide are under increasing threat of overfishing, disease, pollution and competition from introduced species. In the Murray—Darling Basin (MDB), the largest river system of Australia, more than half the native species are listed as rare or endangered. Active management is required to counteract reduction in population sizes, prevent local extinctions and to maintain genetic diversity. We describe the first comprehensive set of DNA barcodes able to discriminate between all 58 native and introduced species of freshwater fish recorded in the MDB. These barcodes also dis

Abstract:
Species diversity can be inferred using multiple data types, however, results based on genetic data can be at odds with patterns of phenotypic variation. Tiger beetles of the Cicindelidia politula (LeConte, 1875) species complex have been taxonomically problematic due to extreme phenotypic variation within and between populations. To better understand the biology and taxonomy of this group, we used mtDNA genealogies and multilocus nuclear analyses of 34,921 SNPs to elucidate its evolutionary history and evaluate the validity of phenotypically circumscribed species and subspecies.

Abstract:
A new, externally atypical Nyodes is described from Equatorial Africa: Nyodes paludicola sp. nov. The new species is compared to the superficially most similar Nyodes steelei Laporte, 1971, and N. punctatoides Laporte, 1973, with the closest genital morphology. The new species is associated with wetland habitats and is widely distributed in West, Central and East Africa. Genetic divergence between the geographically distant populations has been assessed based on mtDNA COI barcodes.

Abstract:
Baetis jaervii sp. n. is described and illustrated. The history and relationships of this taxon to related species are elucidated on the basis of literature and determinations of genetic distance and mtDNA barcodes. B. jaervii is the only representative of the B. vernus group found in northern Europe, the nymphs of which live in lakes. The population from northern Finland earlier assigned to Baetis tracheatus should be transferred to represent B. jaervii.

Abstract:
Leukemias are a group of heterogeneous hematological malignancies driven by diverse genetic variations, and the advent of genomic sequencing technologies facilitates the investigation of genetic abnormalities in leukemia. However, these sequencing-based studies mainly focus on nuclear DNAs. Increasing evidence indicates that mitochondrial dysfunction is an important mechanism of leukemia pathogenesis, which is closely related to the mitochondrial genome variations. Here, we provide an overview of current research progress concerning mitochondrial genetic variations in leukemia, encompassing ge

Abstract:
Coral reefs are the most diverse ecosystem on the planet based on the abundance and diversity of phyla and higher taxa. However, it is still difficult to assess the diversity of lower taxa, especially at the species level. One tool for improving the identification of lower taxa are genetic markers that can distinguish cryptic species and assess species boundaries. Here, we present one such approach for an important and challenging group of reef-building corals. Porites corals are the main reef-builders of many coral reefs in the Indo-Pacific, owing to the massive growth forms of some species.
