Deforestation of the Amazonian rainforest and conversion to agriculture with the use of fire creates a mosaic of occupied lands and secondary forests. Considering the fundamental role of soil macrofauna and the lack of information about its resilience to deforestation, this study characterized the earthworms, ants and other soil arthropod communities in secondary forests of 40 and 20 years of age and in cropping system and pastures prepared with slash-and-burn or chop-and-mulch in the Brazilian Eastern Amazonia. Soil macrofauna was sampled according to the TSBF (Tropical Soil Biological and Fertility) methodology. Four sub-indices and one "macrofauna soil health index" were calculated using five principal component analyses. The macrofauna index identified better soil health in chop-andmulch crops, followed by the 40 yr-old forest and the chop-and-mulch pasture. These results confirmed the fundamental role of old secondary forests for soil biodiversity conservation and the potential of the chop-and-mulch technique to mitigate the effects of land use changes. |

Abstract The production of Coffea arabica L. clone seedlings through the somatic embryogenesis technique is one of the alternatives of greatest demand for coffee producers. However, clones can face difficulties related to acclimatization carried out under greenhouse conditions, which can increase the production costs. A tested alternative with promising results is inoculation with arbuscular mycorrhizal fungi (AMF) during the seedling acclimatization process. Thus, this study aimed to promote the improvement of the seedling production process through somatic embryogenesis associated with inoculation with AMF. For the production of the clones, seedlings were used in the phase when they presented four pairs of leaves (Clone 1 "Fruiting red Catucaí" and Clone 2 "Acauã"), using "somatic embryogenesis" bioreactors, followed by inoculation with Rhizophagus clarus, Gigaspora margarita and Acaulospora mellea, a mixture of R. clarus and G. margarita and a mixture of R. clarus, G. margarita and A. mellea. After six months, agronomic parameters, leaf nutrient contents and root mycorrhizal colonization were evaluated. The studied clones behaved differently when inoculated with AMFs. Clone 1 showed the best development in the greenhouse, which was determined by the agronomic parameters. Thus, Clone 1 is indicated for the production of vigorous seedlings when associated with inoculation with AMFs.

Uma alternativa testada com resultados promissores é a inoculação com fungos micorrízicos arbusculares (FMA) durante o processo de aclimatação das mudas. Assim, o objetivo deste trabalho foi promover a melhoria do processo de produção de mudas através de embriogênese somática associada a inoculação com fungos micorrízicos arbusculares. Para a produção dos clones, plântulas foram utilizadas quando apresentaram quatro pares de folhas (clone 1 "Frutificação vermelha Catucaí" e clone 2 "Acauã") produzidos e desenvolvidos em biorreatores "embriogênese somática" e quando levadas para o viveiro inoculadas com Rhizophagus clarus, Gigaspora margarita e Acaulospora mellea, a mistura de R. clarus e G. margarita e a mistura de R. clarus, G. margarita e A. mellea.
