Taxonomy, or the identification of animal and plant species, can be very time-consuming, especially when a large number of objects are being analized. For example, scientific studies on the global decline of insects are often challenging from a taxonomic point of view. Molecular methods can now replace the human eye in identifying species. For the first time, researchers from the Biological Station Doñana (CISC) in Spain, with the participation of the IGB, have compared the efficiency of conventional and molecular methods using non-biting midges.
