Soil life supports the functioning and biodiversity of terrestrial ecosystems. Springtails (Collembola) are among most abundant soil arthropods regulating fertility flow energy through above- belowground food webs. However, global distribution springtail diversity density, how these relate to fluxes remains unknown. Here, using a dataset representing 2470 sites, we estimate total biomass at 27.5 megatons carbon, which is threefold higher than wild vertebrates, record peak densities up 2...
Springtails (Collembola) inhabit soils from the Arctic to Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database springtail communities that includes 249,912 occurrences 44,999 samples 2,990 sites. These data are mainly raw sample-level records at species level collected predominantly private archives authors were quality-controlled taxonomically-standardised. Despite covering continents, most come European...
Abstract The widespread use of acephate, a common insecticide, raises concerns about its potential impacts on nontarget soil organisms. This study investigated the chronic effects acephate reproduction two key fauna species, springtail Folsomia candida and enchytraeid Enchytraeus crypticus. We exposed these organisms to in both natural Cambisol tropical artificial (TAS) assess under different environmental conditions. Our results revealed significant reductions for with ranging from 38% 49%...

Here, using a dataset collected from 2,470 sites, we estimate total biomass at 29 Mt carbon (threefold higher than wild vertebrates 6 ) record peak densities up million...
Abstract The relationship between the productivity of crops agricultural interest and their interactions with physicochemical soil properties is widely explored. However, there still a gap concerning contribution biological attributes especially crop structures organism communities within soil, such as enchytraeids. This paper aimed to evaluate diversity enchytraeids in subtropical soils soybean no‐tillage system. study was conducted growing grounds working under no‐till farming systems...
The objective of this study was to identify differences in land use systems and forest management on the diversity soil fauna Collembola eco-morphotypes, their relationship with physical-chemical attributes soil. Sampling carried out Native Forest (NF), Araucaria Reforestation (AR) Eucalyptus (ER). In all, 19 taxonomic groups were identified, which Formicidae most abundant, addition 21 morphotypes springtail. For TSBF, AR presented highest abundance NF values wealth groups. Potassium...
This study investigated the impact of landscape fragmentation on springtail (Collembola) communities in subtropical regions. We collected soil core samples across landscapes with Low, Medium, and High levels. Springtail morphotypes were identified characterized using Eco-Morphological Index (EMI), incorporating physical, chemical, microbiological properties litter. Our findings reveal a negative diversity. Landscapes lower exhibited higher beta diversity, indicating more diverse distinct...
Brazil is considered a megadiverse country, but the soil fauna still very poorly known.
