A major challenge in network ecology is to describe the full-range of species interactions in a community to create highly-resolved food-webs. We developed a molecular approach based on DNA full barcoding and mini-barcoding to describe difficult to observe plant-leaf miner-parasitoid interactions, consisting of animals commonly regarded as agricultural pests and their natural enemies. We tested...

Gobiids constitute a major proportion of fish population in both tropical and temperate freshwater as well as marine ecosystem. Due to their small size, cryptic ecology and ambiguous morphological characters, gobiids diversity was not documented completely. In this study, DNA barcodes were generated for 11 species of gobiids, collected from the Ashtamudi Lake, India. The mitochondrial COI gene ...

DNA barcoding has been proved successful to provide resolution beyond the boundaries of morphological information. Hence, a study was undertaken to establish DNA barcodes for all morphologically determined Hexacentrus species in China collections. In total, 83 specimens of five Hexacentrus species were barcoded using standard mitochondrial cytochrome c oxidase subunit I (COI) gene. Except for H...

Sand flies include a group of insects that are of medical importance and that vary in geographic distribution, ecology, and pathogen transmission. Approximately 163 species of sand flies have been reported in Colombia. Surveillance of the presence of sand fly species and the actualization of species distribution are important for predicting risks for and monitoring the expansion of diseases whi...

Unlike distinct species, closely related species offer a great challenge for phylogeny reconstruction and species identification with DNA barcoding due to their often overlapping genetic variation. We tested a sibling species group of pine moth pests in China with a standard cytochrome c oxidase subunit I (COI) gene and two alternative internal transcribed spacer (ITS) genes (ITS1 and ITS2). Fi...

The representatives of the genus Ametropus (Insecta, Ephemeroptera) were recorded 80 years ago in Georgia. Due to taxonomic uncertainty, specimens considered potentially new taxa. Since then, no other record has been documented from whole South Caucasus and its nearby regions further south. In present contribution, we provide a Alazani River (Kura Basin, Georgia). Morphological DNA barcoding CO...

We analyze the morphological and genetic variability within and between seven species of Acesta and specimens recently collected in the northwest Atlantic using traditional morphological measurements, landmark-based geometric morphometrics, and the cytochrome oxidase subunit I (COI) gene sequences, with particular emphasis on North Atlantic species. Shell morphology and external shell appearanc...

This study is focused on the aquatic environments of Sian Ka’an reserve, a World Heritage Site. We applied recently developed protocols for rapid assessment most animal taxa inhabiting any freshwater system using light traps and DNA barcodes, represented by mitochondrial gene Cytochrome Oxidase I (COI). barcoded 1037 specimens comprising mites, crustaceans, insects, fish larvae from 13 close or...

We tested the performance of DNA barcoding in Acridoidea and attempted to solve species boundary delimitation problems in selected groups using COI barcodes. Three analysis methods were applied to reconstruct the phylogeny. K2P distances were used to assess the overlap range between intraspecific variation and interspecific divergence. "Best match (BM)", "best close match (BCM)", "all species b...
