Contribution to the fresh water Tardigrada from Barentsøya, Svalbard (78°30'N)

open access: yesFauna Norvegica, 1991
Fifteen species and one subspecies of Tardigrada were found in the littoral zone of 18 fresh water bodies on the Talaveraflya. All taxa are new records for Barentsøya; Hypsibius antarcticus and Macrobiotus dianeae were not previously reported from ...

A phase transition modulates the protective function of a tardigrade disordered protein during desiccation

open access: yesProtein Science, Volume 34, Issue 10, October 2025.
Abstract Water is essential for active life, yet some organisms, such as tardigrades, can survive prolonged periods of drying‐induced dormancy. Cytoplasmic abundant heat‐soluble (CAHS) proteins are disordered proteins that undergo a phase transition from the solution to gel state.

Freshwater tardigrades from Hopen, Svalbard (76°31'N)

open access: yesFauna Norvegica
Seventeen species of Tardigrada were found in submerged mosses of 17 freshwater bodies from the SE part of the island of Hopen (Svalbard). Fourteen species are new records for Hopen; Pseudechiniscus islandicus was not previously reported from Svalbard ...

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

Final Note of Special Issue “Tardigrades Taxonomy, Biology and Ecology”

open access: yesDiversity, 2020
Tardigrada (water bears) are microscopic invertebrates inhabiting aquatic (freshwater and marine) and terrestrial habitats. They are thriving in almost all Earth ecosystems from deepest oceans to highest mountains, from tropics to polar regions.

Biodiversity in mountain soils above the treeline

open access: yesBiological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Dietary adaptations along the northern limit of distribution: what does the smooth snake Coronella austriaca eat in Norway? Metabarcoding of stomach content and visual analysis of faeces

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators and prey species. How species adapt to high latitudes and to future climate changes will be impacted both by direct interactions with the ...

Diversidad y morfometría de tardígrados de una ciudad mediana de la región Neotropical: Santa Rosa (La Pampa, Argentina) [PDF]

open access: yes, 2007
Tardigrade diversity was studied in a medium–sized city in the Neotropical Region: Santa Rosa (La Pampa, Argentina). Samples were collected between February 1999 and January 2000 from lichens and mosses growing on sidewalk trees of the urban and ...
