“…The main properties currently generally evaluated to characterize soil invertebrate communities are species diversity and abundance, but often they do not explain some effects of soil degradation exhaustively. Synthetic indices, such as Simpson, Pielou and Shannon indices, can integrate some information about soil fauna [4], but do not take into account the ecological role of each taxon [5], Protura and Diplura are groups that generally occur rarely and related to which scarce information is available. Nevertheless, their morphologic traits, such as their small chitin-less body, and their trophic functions make them potential indicators of soil stability [14].…”

The dramatic increase in soil degradation in the last few decades has led to the need to identify methods to define not only soil quality but also, in a holistic approach, soil health. In the past twenty years, indices based on living communities have been proposed alongside the already proven physical-chemical methods. Among them, some soil invertebrates have been included in monitoring programs as bioindicators of soil quality. Being an important portion of soil fauna, soil arthropods are involved in many soil processes such as organic matter decomposition and translocation, nutrient cycling, microflora activity regulation and bioturbation. Many studies have reported the use of soil arthropods to define soil quality; among taxa, some have been explored more in depth, typically Acari and Collembola, while generally less abundant groups, such as Palpigradi or Embioptera, have not been investigated much. This paper aims to evaluate and compare the use of different soil microarthropod taxa in soil degradation/quality studies to highlight which groups are the most reported for soil monitoring and which are the most sensitive to soil degradation. We have decided not to include the two most present and abundant taxa, Acari and Collembola, in this paper in consideration of the vast amount of existing literature and focus the discussion on the other microarthropod groups. We reported some studies for each taxon highlighting the use of the group as soil quality indicator. A brief section reporting some indices based on soil microarthropods is proposed at the end of this specific discussion. This paper can be considered as a reference point in the use of soil arthropods to estimate soil quality and health.

“…Although, this balance between soil protection and yield has been achieved under some conditions but not in others (Gómez, ). This activity, and the consequent reduction of semi‐natural habitats in landscapes, has impoverished the arthropod fauna in the agro‐ecosystem of olive orchards (Ruano et al ., ; Santos et al ., ; Cotes et al ., ; Jerez‐Valle et al ., ). Therefore, to promote biodiversity and prevent erosion during the rainy period of the year, especially in the case of perennial crops (Duarte et al ., ), the European Union encourages the generation or maintaining of ground cover vegetation (natural or sown).…”

1 Agricultural intensification has greatly affected biodiversity in recent decades. One common and recent transformation that has taken place in Mediterranean countries is olive grove intensification, although its effects on biodiversity have rarely been studied. 2 In the present study, we investigated the effect of soil management practices, with versus without soil cover crops, on the arthropod abundance, richness, diversity and species composition in Andalusia olive groves, South Spain. 3 The results obtained show that these soil cover crops positively affect the diversity of arthropods, along with other variables such as the diversity of the plant community and Shannon index of the landscape. By contrast, the number of arthropods was higher in olive groves with bare ground as a result of the abundance of two families (Entomobryidae and Aeolothripidae), which comprised more than 50% of all the individuals collected. 4 Rank abundance diagrams and multivariate analyses showed differences between the two types of soil management systems with respect to the composition of families. 5 In conclusion, soil cover crops strongly improve the diversity of arthropods in olive orchards, which helps to maintain biodiversity in these intensive agroecosystems at the same time as improving other ecosystems services, such as soil fertility and the prevention of soil erosion.

“…There is extensive scientific evidence that olive grove intensification causes a decline in the diversity of ants and other soil arthropods (Ruano et al ., ; Santos et al ., , b; Cotes et al ., ; Jerez‐Valle et al ., ). However, compared with studies on ant taxonomic diversity, there are very few studies investigating the effects of olive grove soil management intensification on any variable measuring ant functional diversity.…”

1 Agricultural intensification is one of the major drivers behind biodiversity loss in Mediterranean agroecosystems. The intensification of olive groves as monoculture in large areas of the southern Spain has had important effects on biodiversity and ecological processes. 2 In the present study, we explore the olive grove soil management practices effects on taxonomic and functional diversity of ants along a gradient of soil management intensity. We predict that both species richness and functional diversity decrease with an increasing intensification of olive grove soil management. We used pitfall traps to sample ants in 24 olive groves subject to different soil management regimes in southern Spain, and then compared ant species richness and functional diversity (FD). 3 Nonploughed organic farms showed higher species richness. Ploughing was observed to be the soil management practice with the greatest negative effect on ant species richness. 4 Three functional traits significantly responded to soil management intensity, with tibia length and head width showing a higher FD in organic farms and diet showing a lower FD in ploughed farms. 5 The results of the present study highlight the negative effects of olive grove ploughing on ant biodiversity and provide novel evidence of the nonploughing organic farming role with respect to maintaining higher levels of ant functional diversity.
