Multiomics study of a heterotardigrade, Echinisicus testudo, suggests the possibility of convergent evolution of abundant heat-soluble proteins in Tardigrada [PDF]
BMC Genomics, 2021 Background Many limno-terrestrial tardigrades can enter an ametabolic state, known as anhydrobiosis, upon desiccation, in which the animals can withstand extreme environments.

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 ...

Homology of the head sensory structures between Heterotardigrada and Eutardigrada supported in a new species of water bear (Ramazzottiidae: Ramazzottius) [PDF]
Zoological Letters, 2023 Phylum Tardigrada is represented by microscopic eight-legged panarthropods that inhabit terrestrial and marine environments. Although tardigrades are emerging model animals for areas of research including physiology, evolutionary biology, and ...

Metabolite phosphatase from anhydrobiotic tardigrades. [PDF]
FEBS JIn this study, we determined the crystal structure of a Ferritin‐like protein widely distributed among intriguing organisms such as tardigrades, which show tolerance to extreme environmental conditions. We identified a dinuclear metal‐binding site, which we found harbors phosphatase activity toward several metabolites, including compounds related to ...

Phylogeography and morphological evolution of Pseudechiniscus (Heterotardigrada: Echiniscidae) [PDF]
Scientific Reports, 2021 Tardigrades constitute a micrometazoan phylum usually considered as taxonomically challenging and therefore difficult for biogeographic analyses. The genus Pseudechiniscus, the second most speciose member of the family Echiniscidae, is commonly regarded ...

"Everything is not everywhere": Time-calibrated phylogeography of the genus Milnesium (Tardigrada). [PDF]
Mol Ecol, 2021 Abstract There is ample evidence that macroscopic animals form geographic clusters termed as zoogeographic realms, whereas distributions of species of microscopic animals are still poorly understood. The common view has been that micrometazoans, thanks to their putatively excellent dispersal abilities, are subject to the “Everything is everywhere but ...

The importance of being integrative: a remarkable case of synonymy in the genus Viridiscus (Heterotardigrada: Echiniscidae) [PDF]
Zoological Letters, 2021 There are two predominant sources of taxonomically useful morphological variability in the diverse tardigrade family Echiniscidae: the internal structure and surface sculpture of the cuticular plates covering the dorsum (sculpturing) and the arrangement ...

Small is beautiful: the first phylogenetic analysis of Bryodelphax Thulin, 1928 (Heterotardigrada, Echiniscidae) [PDF]
Zoosystematics and Evolution, 2020 The phyletic relationships both between and within many of tardigrade genera have been barely studied and they remain obscure. Amongst them is the cosmopolitan Bryodelphax, one of the smallest in terms of body size echiniscid genera.

The complete mitochondrial genome of Echiniscus testudo (Heterotardigrada: Echiniscidae) [PDF]
Mitochondrial DNA. Part B. Resources, 2018 The complete mitchondrial genome of Echiniscus testudo, a cosmopolitan heterotardigrade collected in Japan, has been sequenced using a single molecule real-time (SMRT) sequencing long read after whole genome amplification from a single individual.

New Echiniscidae (Heterotardigrada) from Amber Mountain (Northern Madagascar) [PDF]
Evolutionary Systematics, 2019 A moss sample from the local biodiversity hotspot in lowland rainforest in the vicinity of Amber Mountain, Madagascar, yielded the discovery of two Echiniscus C.A.S. Schultze, 1840 species, of which one is new to science. Echiniscus succineus sp. nov. is
