“…This is because forest systems provide habitats and food resources to soil fauna, enabling greater activity. This finding is corroborated by (RODRIGUES et al, 2016), who found that the occurrence, abundance and diversity of beneficial organisms are all favored in diversified environments. This is especially true when favorable ecological factors exist, such as microclimatic conditions, shelter and food availability Notably, the sampling date (12/5/2015) was chosen considering the climatic characteristics of the region (Figure 1), which allowed the sampling to take place in a period with lower fluctuations in the average, minimum and maximum temperatures.…”

“…The abundance of edaphic faunal organisms in the experimental plots may be associated with the canopy present in each soil occupation system. According to Rodrigues et al (2016), environmental systems in early stages have less canopy and consequently less abundance of organisms in their soil fauna. Silva et al (2018) described that the diversity of soil fauna was influenced by the canopy, especially in areas with crops, compared to areas with eucalyptus and natural savannah-type vegetation, since the canopy is denser and closer to the ground.…”

“…The soil environment can be changed through soil turning, displacing the original invertebrate fauna, altering the edaphoclimatic conditions, type of soil cover, and agrochemicals used to decrease the activity of some individuals or reduce the most sensitive groups. These changes to the soil occupation have a direct influence on the communities (SIQUEIRA; SILVA; PAZ-FERREIRO, 2014) and ecology (RODRIGUES et al 2016;SIQUEIRA et al, 2016) of edaphic fauna. Therefore, it is necessary to understand how the epigeal fauna reflects the different uses and management practices of soil (ROUSSEAU et al, 2014;MARTINS et al, 2018).…”

“…Changes in soil occupation also promote an increase in the quantity and quality of vegetal residues on soil surface. This contributes to an increase in the quantity and quality of food available to the invertebrate fauna of the soil and benefits the abundance and ecology of the epigeal fauna (BATISTA et al, 2014;MUELLER et al, 2015;BEDANO et al, 2016;FRANCO et al, 2016, RODRIGUES et al, 2016FARIAS;HERNADEZ, 2017;ČUCHTA et al, 2019). However, Assis et al (2017), Castro et al (2018), Carvalho et al (2018) and Čuchta et al (2019) described that the inadequate occupation of soil and crops contributes to an imbalance in the dynamics of the taxonomic groups that compose the epigeal fauna.…”

Diversity of Edaphic Fauna in Different Soil Occupation Systems

et al. 2019

Soil is the habitat for a number of living organisms that perform essential functions within the ecosystem; their functions and interactions are modified according to different ways of land occupation. Thus, the objective of this study was to evaluate the diversity of edaphic fauna in different soil occupation systems. The study was carried out in different soil occupation systems: millet, maize, soybean, eucalyptus, preserved cerrado, disturbed cerrado, and pasture, with 130 pitfall traps installed per treatment. Soil fauna organisms were identified at the level of large groups (orders and family), and then examined under the following biological diversity indices: Shannon index, Pielou index, average and total richness, and abundance. The highest abundance was found under millet growing conditions (9,974 individuals), and the lowest abundance values were found in soybean soil (222 individuals) and maize (824 individuals). Uniform distribution of groups in the area with soybean crops, due to the homogeneous management of the area, provided the highest biological index (H'=2.69). Principal component analysis (PCA) explained 50.9% of the data along the main axis and 34.6% of the data along the secondary axis. The different systems of soil occupation showed different abundance and diversity, demonstrating how soil occupation interferes with the dynamics of the invertebrate soil fauna.

“…Reduced biodiversity results in changes in ecological functions, such as loss of self-regulation capacity, reduced genetic variability, population imbalances, and imbalances in the relationships between different groups, which affect the environment (Lopes et al, 2017;Nicholls & Altieri, 2007;Cardinale et al, 2012;Peñalver-Cruz et al, 2019). Therefore, the study of edaphic invertebrates is a very important tool in the preservation and sustainable management of the ecosystem, in order to maintain the integrity of native forest areas and help areas under recovery, taking advantage of the interrelations with soil and vegetation provided by edaphic invertebrates (Rodrigues et al, 2016).…”

Edaphic Invertebrates as Indicators of Soil Integrity Quality

Bioindicator organisms, such as edaphic invertebrates, are constantly used to assess disturbance, as they exhibit responses such as reduced community and changes in diversity, affecting the local ecosystem. The aim of this study was to compare the impacts of disturbance on the edaphic invertebrate community in both a pasture area and a native forest area, during summer and winter. Samplings were conducted for nine days using pitfalls. Bray-Curtis analyses, NMDS, ANOSIM, and SIMPER were applied. There was difference in richness and diversity between areas and seasons. Native forest pitfalls had higher similarity in abundance and diversity in both seasons than pasture pitfalls. Specimens belonging to 20 orders were collected; of those, Collembola, Hymenoptera, Diptera, and Hemiptera had the highest number of individuals. Seasonal influence on the organisms was evident. The impact on edaphic invertebrate community located in the pasture area showed that native forest has higher complexity and structural stability.

Single cultivation versus sweet potato and popcorn intercropping: benefits over edaphic fauna in ecological-based system

et al. 2021

The objective of this study was to evaluate the diversity and abundance of edaphic fauna organisms in single and intercropped systems of sweet potato (Ipomoea batatas) and ecologically-based popcorn (Zea mays) in Red Oxisol, in the Northwest region of the state of Rio Grande do Sul, Brazil. Four sweet potato cultivars were used in single systems and intercropped with popcorn: BRS Amélia, BRS Rubissol, BRS Cuia and Crioula. The soil fauna assessment was carried out using PROVID-type traps. Richness, abundance and the dominance indices of Shannon (H') and Simpson (D) were determined. The orders Coleoptera, Hymenoptera, Collembola and Orthoptera, were dominant in both cultivation systems. The single cultivation showed a greater number of organisms in the orders Isopoda and Collembola, whereas in the intercropped system, the orders Lepidoptera and Hymenoptera stood out. The intercropping cultivation of sweet potato and popcorn shows highest diversity and abundance of soil organisms compared to the single cultivation.
