Amphibians globally are in decline, yet there is still a tremendous amount of unrecognized diversity, calling for an acceleration of taxonomic exploration. This process will be greatly facilitated by a DNA barcoding system; however, the mitochondrial population structure of many amphibian species presents numerous challenges to such a standardized, single locus, approach. Here we analyse intra-...

Our ability to DNA barcode the birds of the world is based on the effective amplification and sequencing of a 648 base pair (bp) region of the mitochondrial cytochrome c oxidase (COI or cox1) gene. For many geographic regions the large numbers of vouchered specimens necessary for the construction of a DNA barcoding database have already been collected and are available in museums and other inst...

An international consortium of major natural history museums, herbaria and other organizations has launched an ambitious project, the 'Barcode of Life Initiative', to promote a process enabling the rapid and inexpensive identification of the estimated 10 million species on Earth. DNA barcoding is a diagnostic technique in which short DNA sequence(s) can be used for species identification. The f...

Illegal selective logging of tropical timber is of increasing concern worldwide. Madagascar is a biodiversity hotspot and home to some of the world's most sought after tropical timber species. Malagasy rosewoods belong to the genus Dalbergia (Fabaceae), which is highly diverse and has a pantropical distribution, but these timber species are among the most threatened as a consequence of intensiv...

Species inventories are essential for documenting global diversity and generating necessary material for taxonomic study and conservation planning. However, for inventories to be immediately relevant, the taxonomic process must reduce the time to describe and identify specimens. To address these concerns for the inventory of arthropods across the Malagasy region, we present here a collaborative...

A new record of the one stick sting fish Minous coccineus (Scorpaeniformes: Synanceiidae) was documented based on morphological traits and DNA barcoding. The species acquired by Department Fisheries during yearly survey “RV Meen Sandhani” from maritime area Bangladesh's continental shelf in Bay Bengal 2018 to 2019. first Bangladeshi marine waters has been verified barcoding morpho-meristic anal...

the taxonomic and phylogenetic status of several taxa previously recognized as subspecies inastragalus sect. anthylloidei is re-assessed based on dna sequences and morphologicalfeatures. we focused on astragalus ebenoides (subsp. ebenoides and subsp. naghadehensis),astragalus murinus (subsp. murins and subsp. bornmuelleri), astragalus remotiflorus (subsp.remotiflorus and subsp. melanogramma), a...

Society faces the complex challenge of supporting biodiversity and ecosystem functioning, while ensuring food security by providing safe traceable food through an ever-more-complex global food chain. The increase in human mobility brings the added threat of pests, parasites, and invaders that further complicate our agro-industrial efforts. DNA barcoding technologies allow researchers to identif...

enes with 3 What characterises DNA barcoding is the attempt to standardise the molecular approach by focusing on one or a few g appropriate levels of among-species divergence, and to secure global accessibility to a common database. Additionally, although one gene, cytochrome oxidase I (COI), has proven to be informative across diverse taxa, the aim of DNA barcoding has not been to identify a s...

In the last two decades, there has been a tremendous increase in the global use of herbal medicinal products (HMPs) due to their claimed health benefits. This has led to increase in their demand and consequently, also, resulted in massive adulteration. This is due to the fact that most of the traditional methods cannot identify closely related species in a process product form. Therefore the ur...
