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 |

The massive use of inputs is often applied in common bean for nitrogen (N) supply, better plant development, and to prevent plant disease. Instead, the co-inoculation of Rhizobium, Azospirillum and Trichoderma may play the same role; however, its effects are unknown in common bean. This work aimed to evaluate the effects of co-inoculating three microorganisms on the development, nodulation and grain yield (GY) of a common bean. The experiments were carried out on a randomized block design with four replicates. The treatments were NI: not inoculated; Rt: inoculated with Rhizobium tropici; Rt+Ab: inoculated with Rt and Azospirillum brasilense; Rt+Ab+Ta: inoculated with Rt, Ab and Trichoderma asperellum; Nf120: 120 kg ha-1 of N. In the inoculated treatments, the seeds were treated with Rt inoculant and with Ta inoculant before sowing, using a dose of 10 g of each inoculant kg-1 of seed. The inoculant containing the Ab was sprayed out in a dose of 300 mL ha-1 at the V2/V3 phenological stage. Evaluations were performed for the number of nodules (NN), nodule dry weight (NDW), root dry weight (RDW), shoot dry weight (SDW), pod number (PN), grain number (GN) and GY. NN and NDW were higher in NI and Rt treatments. The Rt+Ab treatment resulted in higher SDW, whereas the same treatment and Rt+Ab+Ta provided higher RDW and SDW, resulting in values similar to those of the Nf120 treatment. Innoculation with rhizobia (Rt) provided PN and GN equivalent to those of the Nf120 treatment. The inoculation (Rt) and co-iconulation (Rt+Ab) resulted on GY of 2946.27 and 2892.42 kg ha-1, respectively, surpassing the Nf120 treatment, which was 2741.91 kg ha-1. These results indicate that Rt inoculation and Rt+Ab co-inoculation can be alternatives to the substitution of nitrogen fertilizers, guaranteeing high GY levels in common bean.
