Limnological Review, 2021 Tardigrades (phylum Tardigrada) are aquatic microecdysozoans that have adapted to survive extreme conditions through the formation of cysts or ametabolic tuns. Their body is covered by a cuticle that plays an important role in their life cycle, including

Experiences with dormancy in tardigrades
Journal of Limnology, 2004 Tardigrades often colonise extreme habitats, in which they survive using both types of dormancy: quiescence and diapause. Together with nematodes and bdelloid rotifers, tardigrades are known to enter quiescence (with several forms of cryptobiosis ...

A tardigrade in Dominican amber [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2021 Tardigrades are a diverse group of charismatic microscopic invertebrates that are best known for their ability to survive extreme conditions. Despite their long evolutionary history and global distribution in both aquatic and terrestrial environments, the tardigrade fossil record is exceedingly sparse.

FISHing for Rickettsia in tardigrades: additional evidence for tardigrade endosymbionts
Zoological Journal of the Linnean Society, 2023 Abstract Many ecdysozoans harbour endosymbiotic bacteria within their microbiota, and these endosymbionts can have a range of positive and negative effects on their hosts. Recent 16S rRNA gene amplicon sequencing studies have provided evidence for endosymbionts within the tardigrade microbiota.

Tolerance to Gamma Radiation in the Tardigrade Hypsibius dujardini from Embryo to Adult Correlate Inversely with Cellular Proliferation. [PDF]
PLoS ONE, 2015 Tardigrades are highly tolerant to desiccation and ionizing radiation but the mechanisms of this tolerance are not well understood. In this paper, we report studies on dose responses of adults and eggs of the tardigrade Hypsibius dujardini exposed to ...

A tale of two tardigrades [PDF]
Proceedings of the National Academy of Sciences, 2016 Horizontal or lateral gene transfer (HGT) involves the transmission of genetic material between separate genomes. It is a major driver of evolutionary innovation in archaea and bacteria (1⇓⇓–4), but the role of HGT in eukaryotes, especially multicellular organisms, remains controversial.

Studia Romanica Posnaniensia, 2020 Rotifers and tardigrades, microscopic animals discovered in the 18th century, have exceptional abilities to survive in hostile conditions. Exposing them to desiccation, extreme temperatures, and vacuum, scientists wanted to determine whether these ...

Evidence of avian-mediated long distance dispersal in American tardigrades [PDF]
PeerJ, 2018 Terrestrial tardigrades, commonly known as “water bears”, are part of a phylum of microscopic, aquatic invertebrates famous for cryptobiosis and space travel, but little is known about their modes of dispersal on Earth.

Frontiers in Physiology, 2023 Even for tardigrades, often called the toughest animals on Earth, a hypomagnetic field (HMF) is an extreme environment. However, studies on the effect of HMF on tardigrades and other invertebrates are scarce.
