Litter and fauna functional identity effects on litter decomposition
Résumé
Main issue : is functional biodiversity as a key driver of organic matter degradation ?
• Soil fauna represents a huge diversity of soil animals involved in a great number of soil ecosystem services (Lavelle et al. 2002, Kibblewhite et al., 2008)
• In spite of their crucial issues, the relations between soil fauna biodiversity and soil behaviour are still poorly understood and very poorly predicted.
• The use of functional groups and trait-based approaches improved the understanding of soil invertebrate diversity effect on soil functions compared to historiccaly taxonomic approaches.
• Soil macrodetritiovres roles are pivotal in sofar as they are implied in organic matter degradation and participate to the regulation of biogeochemical cycles of elements such as carbon and nitrogen
• Studies using a functional approach mainly concern litter decomposition in forest systems. Meadow systems are scarcely studied.
• There are only scarce studies which dela with both functional diversity of litter and soil invertebrates.
