“…Moreover, several factors, e.g., environmental circumstances, soil characteristics (soil pH, soil type, organic matter content, soil structure, etc. ), species community (soil fauna, plants, and microbes), and period of sampling can affect the density, composition and species activity [8,[88][89][90][91]. This change could be explained by regional or local differences in Collembola abundance [92], but there were no found in the Shannonindex, Simpsonindex, and pielou of the total number of Collembola between six different treatments studied in our experiment.…”

Agriculture itself has been considered one of the leading reasons for biodiversity loss because of the huge quantity of land dedicated to just this activity, and agricultural intensification has impacted soil organisms at several taxonomic levels. Soil biota is a vital component of the agricultural system, providing essential ecosystem services while also having synergistic impacts on crop yield. Preservation of their diversity becomes a major element of an agricultural sustainability strategy. Many studies focused on agricultural activities' effects on soil organisms, but few of them have focused on their effects on the co-occurrence patterns of their communities. Collembola communities are frequently employed as a substitute for soil organisms; thus, as a surface-dwelling arthropods representative, we investigated assemblages of soil Collembola in reaction to the arrangement of 6 treatments varying in crop rotation (MC: monoculture (corn) vs. CS: corn–soybean rotation) and tillage types (MP: mould ploughing; RT: ridge tillage; and NT: no-tillage). We hypothesized that Collembola communities with strong furca would respond well to the agricultural practices than those with weak furca, and there would be strong co-occurrence between species of Collembola communities belonging to the treatments with less intensity of soil disturbance and more variation in crop rotation. Our study found no clear evidence of a beneficial effect of crop rotation on Collembola communities. Although Collembola with strong furca shows higher abundances in plots with mold plowing, weak furca abundances were not showing any difference (differences in abilities to move fast from harsh habitats could be the reason for different responses of these two groups). Network analysis revealed that Collembola assemblages seem to occur more responsive to tillage intensity than crop rotation. Network graphs of treatments with ridge tillage are significantly more clustered than all others. For the first time, we can show that assemblages of springtails in agriculture were distinguished by a pattern of co-occurrence alongside agricultural practices (crop rotation, soil tillage), showing variations in the disturbance of soil and soil nutrients. Our results, contrary to our expectations, demonstrated that the effects of agricultural activities on Collembola abundance and diversity could be weak after long-term application of the same treatment, but still, they will clearly affect the bonds between Collembola species by affecting their co-occurrence pattern in Collembola communities.

“…In addition, several factors can influence composition, density and activity of species, such as climatic conditions, soil properties (soil type, structure, pH, organic matter content, etc. ), species community (plants, microorganisms and soil fauna) and sampling period (Baretta et al, 2008; Cluzeau et al, 2012; Pflug & Wolters, 2002; Roźen, Sobczyk, Liszka, & Weiner, 2010; Schröder, 2008). This difference may be because of differences in regional or local variations in springtail abundance (Culik et al, 2006).…”

Tillage systems in conservation agriculture such as no‐tillage (NT) and crop‐livestock integration (CLI) have been proposed to limit the negative impacts of intensive agriculture. Soil organisms such as Collembola are good indicators because they respond to a variety of environmental and ecological factors and their community structure indicates a change in land management. In this study, we propose to assess the relationships between springtail biodiversity in management systems with a history of NT and CLI. For both management systems, nine points were sampled, distributed in a 30 × 30 m sampling grid, in three municipalities on the Southern Santa Catarina Plateau, Brazil. Springtails were collected using a metal cylinder (5 cm diameter × 5 cm deep) and identified at the species level. At the same point, samples were collected to evaluate soil properties (chemical, physical and microbiological). In total, 538 individuals were collected, distributed in 24 species, 293 individuals (18 species) in NT and 245 individuals (17 species) in the CLI system. Soil management systems studied did not affect the total number of individuals and richness. The NT system had a greater association with epigeic species, while the CLI system was more associated with hemiedaphic and edaphic species, which is related to the site‐specific differences in soil conditions. In both soil management systems, the species were influenced by a range of soil properties. The species Isotomurus sp. 1 and Lepidocyrtus sp. 1 were more influenced by soil properties in the NT system, while the species Proisotoma sp. 1, Sminthurinus sp. 1 and Tullbergia antarctica were more influenced by soil properties in the CLI system, compared to the others. Collembola community structure and species diversity were modified by the soil management systems. Our results suggest that the Collembola community may indicate changes across land management systems in conservation agriculture.

“…A mesofauna edáfica participa de várias funções e serviços do ecossistema, desempenhando papel relevante no equilíbrio do sistema biológico terrestre, refletindo no meio ambiente os impactos de origem antrópica ou natural. Os organismos da mesofauna atuam decompondo a matéria orgânica e disponibilizando nutrientes no solo, auxiliando no crescimento de plantas; influenciam na dinâmica do nitrogênio e carbono no solo, especialmente porque eles podem se mover no substrato e visitar áreas maiores durante sua busca de alimentos; e são importantes na rotatividade de nutrientes, que interfere nas atividades microbianas e consequentemente, respiração do solo e produção de alimentos (SCHRÖDER, 2008).…”
