The taxonomy of Sattleria Povolný from the high mountain systems on the Balkan Peninsula and the adjacent parts of the Alps (south-eastern Alps, Dinaric Alps, Rila Mountains) is revised based on recently collected material and re-examined museum vouchers. Adult morphology and molecular data of the COI barcode region support the existence of six strictly allopatric species in this area, includin...

Abstract Characterization of species diversity zooplankton is key to understanding, assessing, and predicting the function future pelagic ecosystems throughout global ocean. The marine assemblage, including only metazoans, highly diverse taxonomically complex, with an estimated ~28,000 41 major taxonomic groups. This review provides a comprehensive summary DNA sequences for barcode region mitoc...

Herein we discuss the geographic structure of genetic variation of the widely distributed lesser treefrog (Dendropsophus minutus) from the Guianas in a preliminary examination of the status of Guianan populations referred to this taxon. Current sampling is insufficient to determine the status of all lineages of this complex within South America, but our results do indicate the presence of crypt...

Greenhouses in botanical or zoological gardens are home to dozens of species of invertebrates that were introduced alongside plants or potting soil. Our study presents the description of an alien species of earwig, Euborellia arcanum sp. nov., found in tropical greenhouses in Leipzig and Potsdam (Germany) and in Vienna (Austria), including information about its biology in breeding culture. The ...

Analysis of the DNA barcode region of the cytochrome c oxidase 1 gene from a specimen of the extinct Jamaican sunset moth, Urania sloanus, places this species as a sister to the Central American U. fulgens. We found that all Urania F. species were closely related (<2.8% maximum divergence at COI), with the Cuban endemic U. boisduvalii appearing as sister to the rest. The low divergence in DNA b...

Podonomus Philippi was recently found in Brazilian inselbergs. In this study, we used sequences from the barcode region of cytochrome c oxidase I (COI) to assess Podonomus molecular diversity from mountains in Southeastern Brazil. Our results revealed the adult female and the larvae of Podonomus pepinellii Roque and Trivinho-Strixino, 2004 and extended the known geographical distribution of the...

Because many animal species are undescribed, and because the identification of known species is often difficult, interim taxonomic nomenclature has often been used in biodiversity analysis. By assigning individuals to presumptive species, called operational taxonomic units (OTUs), these systems speed investigations into the patterning of biodiversity and enable studies that would otherwise be i...

BACKGROUND Many studies have shown the suitability of sequence variation in the 5' region of the mitochondrial cytochrome c oxidase I (COI) gene as a DNA barcode for the identification of species in a wide range of animal groups. We examined 471 species in 147 genera of Hemiptera: Auchenorrhyncha drawn from specimens in the Canadian National Collection of Insects to assess the effectiveness of ...

The genus Rhachotropis has the widest geographic and bathymetric distribution of all amphipod genera worldwide. Molecular and morphological investigations of specimens sampled around Iceland and off the Norwegian coast allow the first insights into the relationships of North East Atlantic Rhachotropis. The 31 cytochrome oxidase subunit I (COI) sequences generated for this study were assigned 13...

Indicator vector analysis of a nucleotide sequence alignment generates a compact heat map, called a Klee diagram, with potential insight into clustering patterns in evolution. However, so far this approach has examined only mitochondrial cytochrome c oxidase I (COI) DNA barcode sequences. To further explore, we developed TreeParser, a freely-available web-based program that sorts a sequence ali...
