Phylogeography and morphological evolution of Pseudechiniscus (Heterotardigrada: Echiniscidae) [PDF]

open access: yesScientific 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 ...

The complete mitochondrial genome of Echiniscus testudo (Heterotardigrada: Echiniscidae) [PDF]

open access: yesMitochondrial 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.

The importance of being integrative: a remarkable case of synonymy in the genus Viridiscus (Heterotardigrada: Echiniscidae) [PDF]

open access: yesZoological 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 ...

RevisedCornechiniscus(Heterotardigrada) and new phylogenetic analyses negate echiniscid subfamilies and tribes [PDF]

open access: yesRoyal Society Open Science, 2020
Echiniscidae are undoubtedly the most thoroughly studied lineage of the class Heterotardigrada. Recently, new subfamilies and tribes grouping echiniscid genera based on traditionally recognized morphological clues have been proposed. Here, by integrative

Multiomics study of a heterotardigrade, Echinisicus testudo, suggests the possibility of convergent evolution of abundant heat-soluble proteins in Tardigrada [PDF]

open access: yesBMC 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]

open access: yesAngew Chem Int Ed Engl
We 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 ...

The diversity of Indian Ocean Heterotardigrada

open access: yesJournal of Limnology, 2007
Information about Indian Ocean tardigrades is quite scarce and in most cases refers to species in coastal coralline sediment and occasionally in abyssal mud.

Homology of the head sensory structures between Heterotardigrada and Eutardigrada supported in a new species of water bear (Ramazzottiidae: Ramazzottius) [PDF]

open access: yesZoological 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]

open access: yesFEBS J
In 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 ...

"Everything is not everywhere": Time-calibrated phylogeography of the genus Milnesium (Tardigrada). [PDF]

open access: yesMol 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 ...
