Project summary: 
Recently, the ANDEEP (Antarctic Deep Sea Biodiversity) campaigns have explored the Antarctic deep sea basins for the first time and a large number of amphipod crustacean samples were collected for morphology and DNA studies, complementing the existing collections at the RBINS of samples originating from the Antarctic continental shelf. For this short term project, we want to test the suitability of two mitochondrial genes (COI and 16S rRNA) as barcoding markers in Antarctic lysianassid amphipods. A database of these short DNA fragments will be constructed and used for rapid and standardized identifications, contributing to the Barcode of Life. Moreover, sequencing of these two mitochondrial genes might permit us to detect potential cryptic species. Molecular data have identified cryptic species in an increasing number of circum-Antarctic taxa, which have been shown to be composed of a several species with a restricted distribution. Identifying cryptic species and their distribution can be useful to investigate the response of Southern Ocean species to global climate change.
