The role of airborne transport was suggested to be especially important for the species of minute, self-fertilizing land snail. Therefore, the force of the wind plays a potentially significant role for the transportation of land snails between patches of fragmented environment. However, so far, the topic of the influence of wind gusts on the disper...

Anhydrobiosis is considered to be an adaptation of important applicative implications because it enables resistance to the lack of water. The phenomenon is still not well understood at molecular level. Thus, a good model invertebrate species for the research is required. The best known anhydrobiotic invertebrates are tardigrades (Tardigrada), consi...
Article
Water availability is one of the most important factors for terrestrial life. Terrestrial habitats may periodically become dry, which can be overcome by an organism's capability to undergo anhydrobiosis. In animals, this phenomenon has been reported for invertebrates, with tardigrades being the best-known. However, different tardigrade species appe...

Abstract. A new heterotardigrade genus, Zealandiscus gen. nov., is erected for the species Echiniscus palmai. Dorsal plates' sculpturing with sparsely distributed large hemispherical protuberances and very tiny granules distinguish this genus from all known members of the genus Echiniscus. The new genus is most similar to the genus Kristenseniscus...

We used high-throughput sequencing of 16S rRNA to test whether tardigrade species are infected with Wolbachia parasites. We applied SILVA and Greengenes databases that allowed taxonomic classification of bacterial sequences to OTUs. The results obtained from both databases differed considerably in the number of OTUs, and only the Greengenes databas...
Article
In the present study, we used integrative taxonomy to describe a population of Diploechiniscus oihonnae (Richters, 1903) from the neotype locality in Merok (Norway). We found no differences in the chaetotaxy formula between the life stages and sex of Dpl. oihonnae. The presence of filaments at B d in some specimens of Dpl. oihonnae appears to be ra...

Tardigrades are microinvertebrates inhabiting almost all aquatic and terrestrial ecosystems throughout the world. They are known for their ability to enter into cryptobiosis and to survive extreme environmental conditions (e.g. lack of water, very high and low temperatures, high doses of radiation, vacuum space). Thanks to these abilities, tardigra...
