Incomplete species inventories for Antarctica represent a key challenge comprehensive ecological research and conservation in the region. Additionally, data required to understand population dynamics, rates of evolution, spatial ranges, functional traits, physiological tolerances interactions, all which are fundamental disentangle different elements Antarctic biodiversity, mostly missing. However, much fauna, flora microbiota emerged ice-free land continent have an uncertain presence and/or unresolved status, with entire biodiversity compendia prokaryotic groups (e.g. bacteria) being All available information requires consolidation, cross-validation, re-assessment steady systematic inclusion order create robust catalogue continent. We compiled, completed revised eukaryotic present terrestrial freshwater ecosystems new living database: terrANTALife (version 1.0). The database includes first integration compendium many microorganisms. also introduce amplicon sequence variants (ASVs) biodiversity. Available literature date were searched species, integrated, taxonomically harmonised curated by experts checklists organisms. final comprises 470 animal (including vertebrates, free-living invertebrates parasites), 306 plants Viridiplantae: embryophytes green algae), 997 fungal 434 protists (sensu lato). provide account microorganisms, including non-lichenised fungi multiple unicellular (Stramenophila, Alveolata Rhizaria (SAR), Chromists Amoeba), jointly referred as "protists". In addition, we identify 1753 bacterial (obtained from 348117 ASVs) 34 archaeal genera (from 1848 ASVs), well as, at least, 14 virus families. formulate basic tree life main lineages listed region their “known-accepted-species” numbers.
