The edaphic fauna plays an important role in the organic matter dynamics of the soil. Millipeds (Diplopoda), centipeds (Chilopoda) and isopods (Isopoda) are among the main components of the soil fauna. Vegetation structure represents one of the main factors influencing composition and diversity of these species that inhabit leaf litter and soil, what is particularly important in the Amazon Forest, where there are several singular vegetation types. Savannah and forest areas stand out in ferruginous hills, which represents one of the most poorly known and highly threatened ecosystems in the Amazon. However, sampling the edaphic fauna in high diversity sites represents a challenging task. Studies have shown that sampling method may influence observed patterns of diversity. From this perspective, the present study aimed to (i) investigate whether assemblages of Chilopoda, Diplopoda and Isopoda differ between vegetation types in the Amazon, (ii) indicate how biological parameters behave in such communities, (iii) identify which method or combination of methods is better suited to sample species richness and (iv) quantify the efficiency of each method regarding time of work and cost. Sampling was conducted by means of hand collection, leaf litter collection, hay-bait traps and soil sampling in four patches, two in the savannah (also called canga) and two in the forest. Richness was higher in forest habitats for Chilopoda and Diplopoda, while for Isopoda there was no significant difference. Species composition also differed between vegetation types for Chilopoda and Isopoda, but not for Diplopoda. Beta diversity between vegetation types was mainly determined by nestedness and balancing, while turnover was the main beta diversity component responsible for differences among methods. Soil sampling and hand collection added more species to the samples, therefore, this combination was the most efficient to access diversity. Our results support the hypothesis that differences in the soil cover promoted by distinct vegetation types influence the species diversity and composition of edaphic fauna. The differences were mainly determined by nestedness and balancing, indicating that the fauna sampled in the canga represents a subset of those present in the surrounding forest. In this sense, even in ecosystems with distinct vegetation types, the combination of soil and surface sampling methods is recommended. Lastly, the present study proposes a set of decision rules and a key to select the most appropriate method to sample the studied taxonomic groups.

Summary: The millipede Oxidus gracilis (C. L. Koch, 1847) is a cosmopolitan introduced species largely recorded in the southeast region of Brazil. The species is considered an agricultural pest with records in poly- or monocultures, and its influence on native communities of plants and invertebrates is still unknown in Brazil. From this perspective, a maximum entropy model was used to explore the predicted distribution of O. gracilis in Brazil. The results showed a highly suitable area in Atlantic Forest (AUC = 0.949 ± 0.02). Considering percent contribution, annual mean temperature (= 54.9) was the main variable which has influenced the modeling. The potentially suitable areas recovered in Atlantic Forest suggest that attention should be given to its possible invasion and the potential damage of O. gracilis to natural communities.

Modélisation de la niche écologique prédisant l’invasion potentielle du mille-pattes non indigène Oxidus gracilis (C. L. Koch, 1847) (Polydesmida : Paradoxosomatidae) dans la forêt atlantique brésilienne

Résumé: Le mille-pattes Oxidus gracilis (C. L. Koch, 1847) est une espèce introduite cosmopolite et largement observée dans la région sud-est du Brésil. L’espèce est considérée comme un ravageur agricole des mono- et polycultures, et son influence sur les communautés indigènes de plantes et d’invertébrés est encore inconnue au Brésil. Dans cette perspective, un modèle d’entropie maximale a été utilisé pour explorer la distribution potentielle d’O. gracilis au Brésil. Les résultats ont montré une zone favorable élevée dans la forêt atlantique (AUC = 0.949 ± 0.02). La température moyenne annuelle (= 54.9) a été la principale variable qui a influencé la modélisation. Les zones potentiellement favorables de la forêt atlantique suggèrent qu’il faut être vigilant quant à sa possible invasion et aux dommages potentiels sur les communautés indigènes.
