Despite the importance of earthworms for soil formation, more is needed to know about how Pre-Columbian modifications to soils and the landscape. Gaining a deeper understanding is essential for comprehending the historical drivers of earthworm communities and the development of effective conservation strategies in the Amazon rainforest. Human disturbance can significantly impact earthworm diversity, especially in rainforest soils, and in the particular case of the Amazonian rainforest, both recent and ancient anthropic practices may be important. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by sedentary habits and intensification patterns of pre-Colombian societies primarily developed in the second part of the Holocene period. We have sampled earthworm com-munities in three Brazilian Amazonian (ADEs) and adjacent reference soils (REF) under old and young forests and monocultures. To better assess taxonomic richness, we used morphology and the barcode region of the COI gene to identify juveniles and cocoons and delimit Molecular Operational Taxonomic Units (MOTUs). Here we suggest using Integrated Operational Taxonomical units (IOTUs) which combine both morphological and molecular data and provide a more comprehensive assessment of diversity, while MOTUs only rely on molecular data. A total of 970 individuals were collected, resulting in 51 taxonomic units (IOTUs, MOTUs, and morphospecies combined). From this total, 24 taxonomic units were unique to REF soils, 17 to ADEs, and ten were shared between both soils. The highest richness was found in old forest sites for ADEs (12 taxonomic units) and REFs (21 taxonomic units). The beta-diversity calculations reveal a high species turnover between ADEs and REF soils, providing evidence that ADEs and REFs possess distinct soil biota. Furthermore, results suggest that ADE sites, formed by Pre-Columbian human activities, conserve a high number of native species in the landscape and maintain a high abundance, despite their long-term nature.

Os objetivos deste trabalho foram testar sob condicoes de solo nu e com cobertura vegetal morta o modelo de GAML,e apresentar a ideia de velocidade de infiltracao basica variavel em funcao da energia cinetica das chuvas, a ser aplicada no modelo original de Green-Ampt no caso de solo nu. Usaram-se dez infiltrometros e um simulador de chuvas, instalados em Latossolo Vermelho-Amarelo da Fazenda Agua Limpa, Distrito Federal. Comparando os resultaods encontrados nos testes de campo com os simulados, verificou-se que o modelo GAML, simulou bem os valores de velocidade de infiltracao e de infiltracao acumulada nos infiltrometros com cobertura vegetal, poram na condicao de solo nu as simulacoes foram prejudicadas. Verificou-se tambem que em condicoes de solo nu a proposta de adotar a velocidade de infiltracao basica variavel em funcao do selamento superficial melhorou a performance do modelo de Green-Ampt, em comparacao com o modelo GAML na previsao da infiltracao de agua. |
