Co- variation in soil biodiversity and biogeochemistry in northern and southern Victoria Land, Antarctica [PDF]

open access: yes, 2006
Data from six sites in Victoria Land (72–77°S) investigating co-variation in soil communities (microbial and invertebrate) with biogeochemical properties showthe influence of soil properties on habitat suitability varied among local landscapes as well as

Tardigrade eggs and exuviae in Antarctic lake sediments: insights into Holocene dynamics and origins of the fauna

open access: yesJournal of Limnology, 2007
The preservation of tardigrade eggs and exuviae in Antarctic lake sediments provided an opportunity to assess post-glacial colonisation and Holocene tardigrade dynamics on the southern continent.

Defining the viability of tardigrades with a molecular sensor related to death. [PDF]

open access: yesPLoS ONE, 2018
The design of experimental protocols that use animal models to assess the impact of a stress on a population or to determine the life span expectancy impact can be time-consuming due to the need for direct observations of dead and living animals.

Parallel evolution of trehalose production machinery in anhydrobiotic animals via recurrent gene loss and horizontal transfer

open access: yesOpen Biology, 2021
Trehalose is a versatile non-reducing sugar. In some animal groups possessing its intrinsic production machinery, it is used as a potent protectant against environmental stresses, as well as blood sugar.

Mechanisms of Desiccation Tolerance: Themes and Variations in Brine Shrimp, Roundworms, and Tardigrades

open access: yesFrontiers in Physiology, 2020
Water is critical for the survival of most cells and organisms. Remarkably, a small number of multicellular animals are able to survive nearly complete drying.

Deep-Sea Tardigrades from the North-Western Pacific, with Descriptions of Two New Species

open access: yesDiversity, 2022
Three deep-sea tardigrade species were identified from the sediment samples collected during the four German–Russian joint deep-sea cruises that were conducted in the North-Western Pacific: Coronarctus sonne sp. nov., Moebjergarctus okhotensis sp.

Integrated pathway modules using time-course metabolic profiles and EST data from Milnesium tardigradum [PDF]

open access: yes, 2012
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 ...

DNA Protection Protein, a Novel Mechanism of Radiation Tolerance: Lessons from Tardigrades

open access: yesLife, 2017
Genomic DNA stores all genetic information and is indispensable for maintenance of normal cellular activity and propagation. Radiation causes severe DNA lesions, including double-strand breaks, and leads to genome instability and even lethality ...
