The current version of the key has been developed primarily using taxa and eco-morphological forms reported from European soils, reflecting the geographical context in which the QBS-ar approach was originally developed and most extensively applied.
We recognize that additional taxa, morphotypes, and regional variants may occur in other biogeographic regions. Researchers, practitioners, and soil biodiversity experts are warmly invited to contribute suggestions for improving the key and atlas.
If you observe soil arthropod groups that are common in your geographical area but are not currently represented in the key, please contact us. Such contributions will help improve the global applicability, accuracy, and completeness of this resource.
