Search for putative gene regulatory motifs in CAHS3, linked to anhydrobiosis in a tardigrade Ramazzottius varieornatus, in vivo and in silico. [PDF]

Genes Cells
Tardigrades 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.

Ramazzottius semisculptus, nuova specie di Hypsibiidae (Eutardigrada).

, 1992
Gli autori descrivono una nuova specie di Eutardigrada, Ramazzottius semisculptus, la cui cuticola presenta una scultura (costituita da tubercoli poligonali) appena visibile e limitata alla estremità caudale del corpo; talvolta essa è completamente ...

Metabolite phosphatase from anhydrobiotic tardigrades. [PDF]

FEBS 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 ...

Applicability of environmental DNA metabarcoding for the hyporheic zone of a stream bed

Environmental DNA, Volume 5, Issue 6, Page 1667-1678, November 2023., 2023
To understand whole riverine biodiversity, including hyporheric zones, it is necessary to develop a method to easily and accurately detect hyporheos communities in hyporheic zones, which currently remains poorly understood. Using eDNA metabarcoding for cytochrome‐c oxidase subunit I (COI) regions, we successfully detected various hyporheos and benthos ...

Effects of synthetic acid rain and organic and inorganic acids on survival and CaCO3 piercing stylets in tardigrades

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.

Reduced ageing in the frozen state in the tardigrade Milnesium inceptum (Eutardigrada: Apochela)

Journal of Zoology, Volume 318, Issue 4, Page 253-259, December 2022., 2022
Tardigrades were subjected to subzero temperature treatment by cooling on agar plates from room temperature down to ‐30°C. The specimens were kept for seven days at ‐30°C without temperature fluctuations, after which the animals were allowed to slowly warm. Live and dead animals were recorded after thawing.

Seasonal turnover in community composition of stream‐associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding

Environmental DNA, Volume 3, Issue 4, Page 861-876, July 2021., 2021
Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. Here, we use environmental DNA metabarcoding of filtered water samples collected in both spring and autumn from five streams in Denmark to address seasonal turnover in community composition of stream macroinvertebrates.
