This work addresses the impact of eight detritivorous species of soil macro-invertebrates (three
millipedes, two woodlice and three earthworms) on short-term carbon mineralization and
mechanical breakdown of beech leaves. The production rate, size class distribution and
OMcontent of invertebrate faeces were also measured. Hierarchical clustering (HC) and
multivariate analysis were performed to find relevant functional groups among the species studied.
Our results identified three groups of macro-invertebrates on the basis of their impacts on beach
leaf degradation (hierarchical clustering): (1) invertebrates that produce fresh faeces with high
N contents compared with other species (i.e. polydesmidae and a single species of lumbricidae);
(2) other lumbricidae that fragment litter into fine particles in their faeces and actively stimulate
CO2 release; (3) other arthropods that fragment litter into coarse particles and have weak impacts
on OM mineralization. These groups over-ride taxonomy, and are proposed as a tentative
functional classification of litter dwelling invertebrates. On the other hand, an idiosyncratic impact
of species was observed in each group, highlighting how much empirical data are still needed
to propose a robust functional classification of litter invertebrates |
