Global fine-resolution data on springtail abundance and community structure.

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.

Synthesis of the Brazilian Poduromorpha (Collembola: Hexapoda) with Special Emphasis on the Equatorial Oceanic Islands.

We present new species and records of Poduromorpha for the Brazilian oceanic islands and synthesis of this order in Brazil. Friesea noronhaensis sp. nov., Friesea rochedoensis sp. nov., Willemia insularum sp. nov. and Paraxenylla zeliae sp. nov. are described and a diagnosis of the morphospecies Acherontiella sp. Lima and Zeppelini 2015 is provided. We present comparative tables, distribution and taxonomic keys of the Friesea, Arlesia, Brachystomella, Acherontiella, Paraxenylla, Xenylla, and Willemia found in the Brazilian oceanic islands and their respective congeners recorded in Brazil.
