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 ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 6, Page 578-589, July 1, 2023., 2023 Tardigrades species exhibit differential sensitivity to synthetic acid rain and natural occurring acids based on pH, acid nature, exposure duration, and species (freshwater species exhibit greater resistance). Aragonite piercing stylets of feeding apparatus maintain their morphology when tardigrades are exposed to acids.

The wealth of shared resources: Improving molecular taxonomy using eDNA and public databases
Zoologica Scripta, Volume 52, Issue 3, Page 226-234, May 2023., 2023 Abstract Public databases such as the NCBI's GenBank have been used as repositories for genomic studies for more than 30 years. In this time, our understanding of the natural world, and especially the genomic world, has expanded vastly, and the size of these databases represent this genomic revolution.

“Everything is not everywhere”: Time‐calibrated phylogeography of the genus Milnesium (Tardigrada)
Molecular Ecology, Volume 30, Issue 14, Page 3590-3609, July 2021., 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 ...

Zoologica Scripta, Volume 50, Issue 3, Page 376-382, May 2021., 2021 Abstract The Tardigrada are a clade with a disputed and complex taxonomy. The three traditional tardigrade classes are the Heterotardigrada, Eutardigrada and the dubious, monotypic Mesotardigrada. A recent molecular study by Guil et al (Zoologica Scripta, 48, 2019, 120) suggested that the Apochela, previously considered an order of Eutardigrada, should

International Journal of Ecology, Volume 2021, Issue 1, 2021., 2021 Construction of cascade dams has been shown to have impacts on fish assemblages and biodiversity. Yet, there is no literature on fish assemblages in the Murum River that connects the cascading Bakun and Murum dams in Sarawak, Malaysia. Hence, study on this modified ecosystem is necessitated to better understand the effects of the cascade dam ...

Search for putative gene regulatory motifs in CAHS3, linked to anhydrobiosis in a tardigrade Ramazzottius varieornatus, in vivo and in silico. [PDF]
Genes CellsTardigrades can survive in an almost completely dehydrated state, known as anhydrobiosis, aided by proteins like CAHS3. Research using a newly developed tardigrade‐specific vector revealed that CAHS3 expression is most pronounced in the epidermis, suggesting tissue‐specific regulation rather than uniform expression.

FEBS Open Bio, Volume 10, Issue 9, Page 1774-1781, September 2020., 2020 The tardigrade Hypsibius exemplaris has low tolerance to direct exposure to 50% relative humidity (RH) without preconditioning in a high RH environment. However, tardigrades pre‐treated with D942, a furancarboxylic acid derivative, partially acquired desiccation tolerance against 50% or even lower RH without preconditioning.

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1160-1172, June 2025.Abstract Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence the turnover of macroelements. However, the investigation of their body elemental composition is complicated due to their low dry weight or sample size hindering the application of established methodological approaches.

Journal of Biogeography, Volume 52, Issue 3, Page 735-749, March 2025.ABSTRACT Aim Tardigrades are important members of Antarctic metazoan communities with many endemic species. Major biogeographic patterns of Antarctic fauna have been identified, in particular regarding the zonation across the Gressitt line, dividing Continental and Peninsular Antarctica. Evidences suggest that Antarctic tardigrades follow this zonation
