“…More studies are needed to better understand these results, but they may be linked to the feeding habits of the edaphic invertebrates under study, which feed mainly on microorganisms and dead organic material (Coleman et al ; Filho et al ; Hopkin ). Hence, the organic matter with the adsorbed pesticide may enter the internal systems of the edaphic organisms, causing toxicity.…”

Pesticides are widely used in agricultural fields to control plant diseases, weeds, and pests; however, the unforeseeable consequences of releasing these compounds into the soil and their effects on terrestrial invertebrates are matters of grave concern. The aim of the present study was to determine the direct impact of 2 pesticides, KRAFT® 36 EC (an insecticide; a.i. abamectin) and SCORE® (a fungicide; a.i. difenoconazole), on nontarget terrestrial invertebrates. Ecotoxicological tests were performed to evaluate the chronic and acute toxicity of these compounds to a potworm (Enchytraeus crypticus), a collembolan (Folsomia candida), and a mite (Hypoaspis aculeifer). The results showed that, for both pesticides, the collembolan F. candida was the most sensitive species, followed by the enchytraeid E. crypticus and the mite H. aculeifer. Effect concentrations at 50% of organisms' reproduction calculated for F. candida, E. crypticus, and H. aculeifer were 0.06, 2.8, and >32 mg of abamectin/kg dry weight soil and 28.9, 125, and 145.5 mg of difenoconazole/kg dry weight soil, respectively. Environmentally relevant concentrations of both pesticides significantly affected the collembolan species. The existence of a potential risk from abamectin and difenoconazole for soil invertebrates even at recommended doses could be identified. Environ Toxicol Chem 2018;37:2919-2924. © 2017 SETAC.

“…Samples were collected using a 3 × 3 point grid, with sampling points at a distance of 30 m from each other and surrounded by a 20-m border, covering 1 ha for each LUS (Rosa et al, 2015;Oliveira Filho et al, 2016). A total of 270 points were sampled, consisting of nine points in five land use systems in three municipalities, in the two study periods.…”

“…Thus, organisms are separated according to their ecomorphological traits and life forms, in order to evaluate their adaptation level to soil life and to overcome the limitations of taxonomic analyses (Parisi et al, 2005). The index was designed with a view to encompass all soil faunal groups (Parisi, 2001;Parisi et al, 2005;Vandewalle et al, 2010;Mohamedova and Lecheva, 2013), but other studies have already adapted and used this methodology to study a specific group of edaphic invertebrates, e.g., springtails (Machado, 2015;Oliveira Filho et al, 2016;Silva et al, 2016), with promising results.…”

Coleopterans (Coleoptera) are major ecosystem service providers. However ecomorphological features that are comparable in a wide range of invertebrates within this group and in various environments must be found, to be able to study regions with different species, contributing to overcome difficulties of the taxonomic approach and understand the functioning of ecosystems. This research addressed the diversity of Coleoptera, using a methodology of ecomorphological traits, as well as their relation with the land use systems (LUS) and the soil properties. The following LUS were evaluated: no-tillage (NT), croplivestock integration (CLI), pasture (PA), Eucalyptus stands (EST), and native forest (NF). Samples were collected using a 3 × 3 point grid (sampling points at a distance of 30 m), in winter and summer, in three municipalities on the Southern Santa Catarina Plateau, Brazil. Coleopterans were collected using the methodology recommended by the Tropical Soil Biology and Fertility Program, based on the excavation of soil monoliths, and on pitfall traps. To evaluate the biological forms (morphotypes) and ecomorphological groups, the ecomorphological index (EMI) methodology was adopted and the modified soil biological quality (SBQ) index was determined. At the same points, samples were collected to evaluate environmental variables (soil physical, chemical, and microbiological properties). Density data underwent nonparametric univariate statistical analysis and multivariate abundance to verify the distribution of coleopterans in the LUS, and the environmental variables were considered as explanatory. Regardless of the LUS, 14 morphotypes were identified, and adult coleopterans with epigean morphologic adaptations were more abundant than hemi-edaphic and edaphic coleopterans, respectively. Morphotype diversity was higher in the systems NF, EST, and PA in summer and in NT in winter. The reductions in SBQ index were not associated with a gradient of land use intensification (NF> EST> PA> CLI> NT), and the index was higher for NF and lower for EST. Principal component analysis (PCA) indicated a different distribution of invertebrates between the LUS. For the edaphic species, better adapted to life in the soil, a relation with NT and CLI was observed, due to more favorable pH values and phosphorus content. In the NF, a greater amount of morphotypes was identified, and the properties related to soil carbon dynamics contributed to explain this distribution. Separation at the morphotype level, taking adaptation level to soil life into consideration, has proved efficient to discriminate the LUS, mainly along with other explanatory environmental variables.

“…Collembolans are bioindicators of soil quality (Machado et al, 2019;Filho et al, 2016), land use intensification impacts (Ponge et al, 2003), and soil pollution (Liu et al, 2018;Fiera, 2009). It could also be a sentinel species of the soil fauna (Caro & O' Doherty, 1999;Gobat et al, 2004) which means, if the Collembolan diversity is threatened, the soil fauna community is threatened as well.…”

The study aimed to determine the effect of Arabica coffee- Benguet pine based agroforestry system on soil-litter collembolan diversity. Under this agroforestry system, two coffee production systems were identified in this study, the Agroforestry Coffee System (ACS) and Lone Coffee System (LCS). ACS have coffee plants growing under Benguet pine trees while LCS have coffee plants that are not under any shade trees. Shannon diversity index (H’), Margalef’s richness index (Dmg), Soil temperature (ST), and Soil Moisture Content (SMC) data were gathered and subjected to linear regression with correlation analysis, and student T-test. The result of this study revealed a higher species richness of collembola under ACS (Dmg =3.52±0.47) than LCS (Dmg = 1.75±0.36). Similarly, ACS has higher diversity index (H’ = 1.68±0.66) than LCS (H’ = 0.90±0.49). ACS ST and SMC was 18.60±0.21℃ and 68.34±12.22% while LCS was 21.24±1.31℃ and 55.38±5.52%. ST had significant negative association with diversity and SMC had positive association with diversity. However, only Dmg had significant correlation with SMC. In regression analysis, 18.7% of the total variation in H’ was explained by ST. While for Dmg, 56.6% and 21.7% of its total variations were explained by ST and SMC, respectively. These results showed that ACS can conserve collembolan diversity because it creates a microclimatic condition favorable for the collembolans. This finding could serve as basis for endeavors to promote and develop agroforestry systems.
