Reaction of Tardigrades (Hypsibius) to Physical and Chemical Extremes
… undetectable metabolic activity, which allows tardigrades {Hypsibius) to escape environmental stress when conditions become unfavorable. In our research, Hypsibius was tested in a laboratory under pH levels of 3 to 10 and a salinity concentration gradient. In the pH experiment, we placed …

Marine Interstitial Tardigrades and Other Meiofauna of Huntington Beach, South Carolina.
… meiofauna. Each taxon (>1500 specimens) and tardigrades was statistically analyzed using three-way ANOVA to compare distribution patterns.</p><p>There were eighteen taxa identified and an estimated 330,338 specimens. The seven dominant taxa were Nematoda, Copepoda, Oligochaeta, Mystacocarida, …

The Observable Effects of Acetylcholine, Succinylcholine, D-tubocurarine and Quinine and Their Binary Combinations on Tardigrades
… succinylcholine, d-tubocurarine, and quinine on tardigrades and to compare these effects to known mammalian reactions. Evidence of synergism or antagonism is sought by combining each drug compound with the other three individually. Procedure. Three species of tardigrades (Milnesium tardigradum, …

A comparative Study of the Population Densities of Various Tardigrada Species
… was to compare the population density of tardigrades in regions as related to: (a) high and low particulate counts without reference to the nature of the particulate present and (b)high and low traffic flow density without reference to particulate counts. Procedure. Bark-lichen samples …

The tardigrada of southwest Virginia: with the addition of a description of a new species from Florida
… suggested phylogenetic schemes for the tardigrades were reviewed and the evidences for affinities of the Tardigrada were presented. A bibliography of the recent literature on the tardigrades was compiled.

Species Redescriptions and Novel data on Study Methodologies, Biodiversity and Phylogeny of limno-terrestrial Tardigrades [Ridescrizione di Specie e Nuovi dati su Metodologie di Studio, Biodiversità e Filogenesi dei Tardigradi limno-terrestri]
I tardigradi costituiscono un phylum di animali (Tardigrada Doyère, 1840) di dimensioni ridotte, che variano da circa 50 a circa 1000 μm, con attualmente quasi 1500 specie note (Degma & Guidetti, 2007, 2024; Guidetti & Bertolani, 2005). Si trovano ovunque sia presente almeno un velo d'acqua e sono …

Controls over the distribution of soil micro-invertebrates in the McMurdo Dry Valleys, Antarctica
… Plectus spp., Eudorylaimus spp., rotifers, and tardigrades are positively associated with higher soil moisture and organic carbon, while Scottnema lindsayae prefers dry, nutrient-poor soils consistent with previous literature. Projected increases in soil moisture favor habitat expansion for …

Molecular Mechanisms of DNA Protection by Tardigrade Damage Suppressor Protein (Dsup): Structural Adaptation and Functional Interactions
… leading to DNA damage, mutations, and disease. Tardigrades, extremotolerant organisms, exhibit remarkable resilience to such stressors, largely attributed to the DNA damage suppressor protein (Dsup). This study investigates the molecular mechanisms underlying Dsup’s DNA-protective function, …

Biodiversity, distribution patterns and trophic position of meiobenthos associated with reduced environments at continental margins
… by harpacticoid copepods, nauplii, polychaetes, tardigrades and other groups (Giere 1993). Because marine nematodes have a worldwide distribution, are the most prominent members of the smaller-sized animals and have a direct link with the sediment and with the processes that occur immediately …

Characterisation of two desiccation-linked dehydrins from Xerophyta humilis
… and micro-animals such as nematodes or tardigrades, have been observed to express Late Embryogenesis Abundant (LEA) proteins as protective mechanisms. However, despite two decades of research, little is understood about their physiological functions and this has led to extensive …

Unravelling the Origins and Evolution of the Animal Kingdom using Genomics
… species, such as platyhelminthes, nematodes and tardigrades. These HG losers, and gainers also had lineage specific homeobox clades,and caused artefactual problems in the phylogenies.

Using Fluorescent Probes to Study the Location and Interaction of Disaccharides within Lipid Bilayers
… freezing and / or oxygen deficiency. The tardigrades ability to withstand such extreme conditions is associated with a decrease in its internal water content and the excess production of a disaccharide known as trehalose. Studies have focused on better understanding this organism survival …

Comparative analysis of meiobenthic diversity across habitats in ancient lakes
… levels. While chironomids, copepods, and tardigrades dominate littoral zones, nematodes are prevalent in profundal zones across all lakes, suggesting that profundal meiofaunal communities reflect stable, low-nutrient conditions, whereas littoral communities capture location specific …

Next generation sequencing technology and phylogenomics enhance the resolution of deep node phylogenies: A study of the Protostomia
… adaptable group of ecdysozoans called the tardigrades or “water bears”. Their rapidly evolving nature has made the phylogenetic affinity of the Tardigrada ambiguous with three alternative hypotheses contesting their placement. A phylogenomic approach was implemented in order to clarify …
