Reduced ageing in the frozen state in the tardigrade Milnesium inceptum (Eutardigrada: Apochela)

Journal of Zoology, Volume 318, Issue 4, Page 253-259, December 2022., 2022
Tardigrades were subjected to subzero temperature treatment by cooling on agar plates from room temperature down to ‐30°C. The specimens were kept for seven days at ‐30°C without temperature fluctuations, after which the animals were allowed to slowly warm. Live and dead animals were recorded after thawing.

Seasonal turnover in community composition of stream‐associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding

Environmental DNA, Volume 3, Issue 4, Page 861-876, July 2021., 2021
Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. Here, we use environmental DNA metabarcoding of filtered water samples collected in both spring and autumn from five streams in Denmark to address seasonal turnover in community composition of stream macroinvertebrates.

A cDNA library of the eutardigrade Hypsibius klebelsbergi Mihelčič, 1959 and analysis of the actin gene

Journal of Limnology, 2007
A cDNA library was constructed from the glacier-dwelling eutardigrade Hypsibius klebelsbergi from more than 2000 individuals collected in the Austrian Central Alps. RNA, DNA and proteins were successively isolated by the Trizol®-method.

Ultrastructure of the digestive system of Ramazzottius tribulosus and Macrobiotus richtersi (Eutardigrada) in relationship with diet

Journal of Limnology, 2007
The ultrastructure of the digestive system of tardigrades was already described in some species, but it has never been studied in relationship to diet.

Dispersal of pollen and invertebrates by wind in contrasting Arctic habitats of Svalbard [PDF]

Polish Polar Research, 2023
Although Svalbard archipelago is considered as a natural laboratory for the environmental studies in the High Arctic, the knowledge on the transport and diversity of bioaerosols (aeroplankton) in the atmosphere is poorly recognized.
