Integrative Taxonomy

Important Tool for Species Identification

Integrative taxonomy plays a crucial role in species identification. By combining classical morphological determination with modern genetic methods, species boundaries can be verified and cryptic species discovered. In a 2018 study, AIM assisted researchers in identifying minor arachnid orders in Peru.

Barcoding supports morphological identification

At the beginning, specialists were not sure whether two morphologically distinct groups actually belonged to different species or whether the smaller individuals were juveniles of the larger one. To clarify this question, individuals of both orders were collected and subjected to a detailed morphological analysis. In addition, a leg or part of a leg from each animal was sent to AIM for the DNA Barcoding Service. The molecular results of the DNA barcoding confirmed the conclusions of the morphological analysis. This meant that the morphologically distinct groups actually belonged to different species. Furthermore, additional morphological characteristics could be identified by the genetic analysis

Integrative approach brings new insights

The combination of classical taxonomy and modern genetic methods is crucial for a comprehensive species description. Only through this integrative approach can the globally accessible, digital catalog of species be completed and new insights gained. The study in Peru is another step towards comprehensive biodiversity coverage and underlines the importance of integrative taxonomy for biological research. The further development and application of such approaches are crucial to expand our knowledge of the diversity of life and to support the protection and conservation of species in the long term.
