“…The co-inertia analysis showed significant covariance (RV: 0.33, p-value: 0.002, Monte Carlo test) between soil macrofauna and edaphic properties (Figure 3). These results coincide with previous studies describing the different relationships between soil macrofauna groups and soil properties (Lima et al, 2010;Vasconcellos et al, 2013;Oliveira et al, 2018). Figure 2.…”

“…Soil macrofauna constitutes an important component of soil biota given the significant impact of their activities in ecosystem functions (Kamau et al, 2017), besides being part of different trophic levels, presents interactions with the edaphic properties (Lavelle et al, 2006). There are physical and chemical soil properties that interact with soil macrofauna groups by influencing their metabolism, while at the same time responding to the behavior of soil macrofauna (Santos et al, 2018;Oliveira et al, 2018). The most cited physical properties are soil texture, soil density and porosity, which are associated with soil structure (Rousseau et al, 2012), while the chemical properties are associated to organic matter content, soil fertility and nutrient availability (Lima et al, 2010).…”

The objective of this study was to evaluate the occurrence of the soil macrofauna in coffee production systems, as well as their relationship with edaphic properties. Therefore, two coffee production systems were selected: coffee plantations at full-sun with conventional management (Intensive) and shaded coffee plantations with organic management (Traditional). In each crop system, three soil samples were collected randomly, in the form of blocks (25 × 25 cm), to a soil depth of 10 cm. In total, 17,109 individuals were recorded in this study being the Oligochaeta group the most representative, regardless of the coffee production system. The average density of soil macrofauna was higher in traditional coffee plantations (p < 0.05) due to the higher density of Oligochaeta, Diplopoda and Blattodea. The traditional coffee plantations provided a better soil chemical fertility reflected in the principal component analysis. Furthermore, these chemical attributes probably could affect the occurrence of the soil macrofauna groups.

“…The remaining eight land uses concentrated in the third cluster, which included pasture (PA), NR, and the other agroforestry systems. It has been proven that the age of the system (Camara et al, 2018), variations in the microclimate caused by absence of a compact canopy (Kamau et al, 2017), the quantity and quality of litter (Oliveira et al, 2018), agricultural practices (Marichal et al, 2014), the use of herbicides (Scoriza et al, 2015), and animal trampling (Morales -Márquez et al, 2018) influence the soil macrofauna. Therefore, we suggest that the unfavorable presence of any of these factors, or Pesq.…”

“…In this scenario, agroforestry systems are land uses that can exhibit great similarities to natural forests due to their forest cover and litter (Baretta et al, 2011;Oliveira et al, 2018). Practices associated with agroforestry systems such as the inclusion of vegetation that is structurally and taxonomically diverse, as well as the presence of a continuous soil cover, seem to be associated with the abundance and diversity of soil macrofauna (Moço et al, 2010;Pauli et al, 2011;Kamau et al, 2017).…”

The objective of this work was to evaluate the soil macrofauna and the bioindicator taxonomic groups associated with different land uses in the Colombian Amazon. Twelve agroforestry arrangements were studied and compared with to the native forest and pasture. For each land use, six monoliths were randomly selected and divided into four layers (litter, and 0-10, 10-20, and 20-30 cm soil depths). The variables considered in the analysis of land use effects were: individuals per square meter, order richness, Shannon’s diversity index, and Pielou’s evenness index. The greatest values for soil macrofauna density and diversity occurred in the forest, in contrast with the pasture. The principal component analysis distinguished land use according to macrofauna diversity, separating the native forest from the other land uses. The cluster analysis indicated the potential of some agroforestry systems to conserve the values of soil macrofauna density and diversity similar to those of the forest. According to the analysis of indicator value, five taxonomic groups (Diplura, Pseudoscorpionida, Araneae, Chilopoda, and Gastropoda), identified as bioindicators, are associated with preserved sites because of the sensitivity of their populations.

“…A macrofauna do solo constitui importante componente da biota edáfica, dado o impacto significativo de suas atividades nas funções do ecossistema (Kamau et al 2017). Esta, opor sua vez possui estreita relação com as propriedades físico-químicas do solo, sendo influenciada pela densidade, porosidade, textura, matéria orgânica, fertilidade e disponibilidade de nutrientes do solo, ao mesmo tempo que seu comportamento influencia na dinâmica edáfica (Rousseau et al 2014;Oliveira et al 2018;Santos et al 2018).…”

A macrofauna edáfica engloba diversos organismos que desempenham importante papel na ciclagem de nutrientes e melhorias na propriedade química e física do solo. Estes organismos são utilizados como bioindicadores do funcionamento dos ecossistemas. Visando tais fatores, objetivou-se avaliar a diversidade populacional dos organismos edáficos em áreas com diferentes pastagens cultivadas. O experimento foi conduzido na zona da mata alagoana, no município de Coruripe, Alagoas. O estudo foi realizado em quatro pastagens com cultivo de Mombaça (Panicum maximum), Tifton 85 (Cynodon spp.), Brachiaria humidicola e Brachiaria Brizantha com uma área de 100m² cada. Foram utilizadas 20 armadilhas do tipo Provid por pastagem. Após 96 horas de instalação das armadilhas, os organismos foram quantificados, identificados e agrupados conforme a ordem e/ou grupo taxonômico. Após as análises dos dados observou-se que a área ocupada com capim B. Brizantha teve a maior diversidade, sendo seguida pelas áreas com Mombaça e tifton 85. A área com menor diversidade foi a ocupada com a pastagem B. humidicola. A ordem Aranae esteve presente em todas as áreas, com representação acima de 3,85 dos indivíduos encontrados. Todas as pastagens apresentaram maior representatividade da ordem Hymenoptera. Os Coleopteras apresentaram população mais densa (2,60) e dominante (0,23) na pastagem de mombaça. A fauna edáfica é sujeita a alteração conforme a alteração da vegetação utilizada para a formação da pastagem.
