DNA Metabarcoding: A Rapid Method for Biodiversity Assessment

DNA-metabarcoding2-2a

DNA metabarcoding refers to the automated identification of multiple species from a single bulk sample containing entire organisms. This offers unprecedented scientific and operation opportunities in order to understand biodiversity distribution and dynamics in a better way. Managing the health of global ecosystems requires detailed inventories of species and a good understanding of the patterns and trends of biodiversity. Evolutionary and ecological studies often rely on our ability to identify the species involved in the process under investigation or our capacity to provide robust biodiversity estimates. For about three centuries, the acquisition of biodiversity data was based on morphological characterization of plants and animals. The idea of identifying species on the basis of molecular markers emerged soon after the advent of molecular biology. Early methods involved the use of hybridization, restriction enzyme digestion or other molecular probes. DNA-based species identification was introduced by Arnot et al. and further development, standardized and advanced by Hebert et al. The ability to extract and store DNA for prolonged periods of time provides a unique opportunity to assess the evolution of biodiversity over time in relation to global change and to develop concrete measures to reserve these features.
