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

Fibril Structure of Desiccation-Protective Tardigrade Protein CAHS-8. [PDF]
Angew Chem Int Ed EnglWe present the atomic structure of the fibril formed by an intrinsically disordered protein that has been shown to be responsible for remarkable environmental stress in tardigrades. X‐ray crystallography reveals a unique mechanism of fibril assembly whereby a single helix forms a stable, antiparallel coiled‐coil dimer, which then assembles into a ...

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 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.

Tun formation is not a prerequisite for desiccation tolerance in the marine tidal tardigrade Echiniscoides sigismundi [PDF]
, 2016 The so-called ‘tun’ state is best known from limno-terrestrial tardigrades and rotifers that rely on this compact body shape for anhydrobiotic survival.

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 ...

Sleeping Beauties, dormancy and resistance in harsh environments: molecular, proteomic and metabolomic aspects - Berlin, Germany, 18-20 May 2008 [PDF]
, 2008 Background Tardigrades are multicellular organisms, resistant to extreme environmental changes such as heat, drought, radiation and freezing. They outlast these conditions in an inactive form (tun) to escape damage to cellular structures and cell death ...

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.

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.
