Describing functional diversity of communities from environmental DNA
Résumé
Comprehensive assessments of functional diversity are needed to understand ecosystem alterations under global changes. The Fun-eDNA approach characterises functional diversity on the basis of eDNA-based inventories by assigning functional traits to taxonomic units. Fun-eDNA allows the joint analysis of an unprecedented number of taxa over broad spatial scales, providing a whole-ecosystem perspective of functional diversity. Fun-eDNA is increasingly used to tackle multiple questions, but aligning eDNA with traits poses several conceptual and technical challenges. Enhancing trait and eDNA databases, improving the annotation of eDNA inventories, interdisciplinary collaboration and conceptual harmonisation of traits are key steps for a comprehensive assessment of diverse taxa.
Overcoming these challenges can unlock the full potential of eDNA in leveraging measures of ecosystem functioning from multi-taxa assessments.
