Although Isotomiellaminor (Schäffer, 1896) (Collembola) is widely distributed in temperate regions, it is one of the less-studied species genetically. The genetic variability and its structure in the common springtail I.minor were investigated on a regional geographic scale using mitochondrial (COI) and nuclear (28S rDNA) markers. A total of nine populations from urban habitats of the Košice city agglomeration and four populations from natural sites of the karst landscape were used for the present study carried out in the Western Carpathians, Slovakia. Up to nine cryptic lineages (MOTUs - molecular operational taxonomic units) were independently recognised by two molecular delimitation methods. In addition, high genetic distances between lineages were observed (p-dist: 10.87-22.75% and K2p: 11.98-27.22%), comparable to the genetic distances between species. This study showed that urban and natural habitats harbour significantly different genetic lineages. Limited dispersal of MOTUs (lineages) between natural and urban populations was also supported by analysis of molecular variance (AMOVA). While the I.minor populations at urban sites were mixtures of different lineages, the populations at natural sites were monophyletic and their haplotypes/genetic lineages were clearly grouped by individual sites. Possible ecological filtering between urban and natural environments within MOTUs is discussed with respect to the evolution of parthenogenetic species I.minor in this habitat complex.

Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the species level collected predominantly from private archives of the authors that were quality-controlled and taxonomically-standardised. Despite covering all continents, most of the sample-level data come from the European continent (82.5% of all samples) and represent four habitats: woodlands (57.4%), grasslands (14.0%), agrosystems (13.7%) and scrublands (9.0%). We included sampling by soil layers, and across seasons and years, representing temporal and spatial within-site variation in springtail communities. We also provided data use and sharing guidelines and R code to facilitate the use of the database by other researchers. This data paper describes a static version of the database at the publication date, but the database will be further expanded to include underrepresented regions and linked with trait data.
