Species are the fundamental units of biological diversity, but their identification and delimitation is often difficult. The difficulties are pronounced in diverse taxa such as insects. DNA barcodes, short standardized segments of the genome, have recently become a popular tool for identifying specimens to species, and are increasingly used as one of the sources of information for species delim...

Environmental conditions in coastal salt marsh habitats have led to the development of specialist genetic adaptations. We evaluated six DNA barcode loci of the 53 species of Poaceae and 15 species of Chenopodiaceae from China's coastal salt marsh area and inland area. Our results indicate that the optimum DNA barcode was ITS for coastal salt-tolerant Poaceae and matK for the Chenopodiaceae. Sam...

This study reports DNA barcodes for more than 1300 Lepidoptera species from the eastern half of North America, establishing that 99.3 per cent of these species possess diagnostic barcode sequences. Intraspecific divergences averaged just 0.43 per cent among this assemblage, but most values were lower. The mean was elevated by deep barcode divergences (greater than 2%) in 5.1 per cent of the spe...

Mangroves are salt-tolerant forest ecosystems of tropical and subtropical intertidal regions. They are among most productive, diverse, biologically important ecosystem and inclined toward threatened system. Identification of mangrove species is of critical importance in conserving and utilizing biodiversity, which apparently hindered by a lack of taxonomic expertise. In recent years, DNA barcod...

Background: Mass disasters often occur in Indonesia, thus require the rapid identification of victims. Teeth can be one primary identifiers besides fingerprints and DNA. It includes dentures worn by victim. The Denture Marking System is a technique for labeling to prevent it being swapped another. Labeling usually uses embedded barcode, made from laminated paper or gravoply plate. Purpose: To c...

Although mites are one of the most abundant and diverse groups of arthropods, they are rarely targeted for detailed biodiversity surveys due to taxonomic constraints. We address this gap through DNA barcoding, evaluating acarine diversity at Churchill, Manitoba, a site on the tundra-taiga transition. Barcode analysis of 6279 specimens revealed nearly 900 presumptive species of mites with high s...

Two new species of Monopelopia Fittkau, 1962 are described and illustrated from the Oriental region based on adult males immature stages. (Monopelopia) recta sp. n. obscurata India a DNA barcode M. is compared with congeneric sequences in NCBI GenBank. Additionally, key to genus reported Palearctic regions given.

I n 2003 zoologists proposed a short, standardized DNA sequence from a uniform locality on the genome to serve as a DNA barcode to identify the species of tissue from almost all animals—reliably, quickly, and economically. In 2008 two New York City high school students, Kate Stoeckle and Louisa Strauss (1), used the accumulating barcode reference library to prove that about 1⁄4 of fish items th...

Metzneria neli Huemer, sp. n., a new species of the family Gelechiidae, is described from France and Spain adults both sexes genitalia are figured. The differs morphologically in DNA barcode all other known representatives genus. It was formerly mixed with tristella Rebel, 1901, therefore this re-described here detail.
