A comparative Study of the Population Densities of Various Tardigrada Species
The problem. The purpose of this investigation 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 …

The tardigrada of southwest Virginia: with the addition of a description of a new species from Florida
… urged. Evidences for the consideration of the Tardigrada as a phylum were presented and a taxonomic hierarchy was erected for this disposition. To complete this taxonomic scheme, the Heterotardigrada and Eutardigrada were accorded class status, the Arthrotardigrada and Echiniscida (= …

A cause for consilience: Utilizing multiple genomic data types to resolve problematic nodes within Arthropoda and Ecdysozoa
… Loricifera, Kinorhyncha, Priapulida, Tardigrada, Onychophora and Arthropoda). Ecdysozoa is the most specious clade of animals to ever exist and the relationships among its eight phyla are still heatedly debated. Similarly also the relationships among the three sub-phyla (Chelicerata, …

Marine Interstitial Tardigrades and Other Meiofauna of Huntington Beach, South Carolina.
… differences in their distribution pattern.</p><p>Tardigrada had 326 specimens collected and 300 identified to species in five genera. Elevation was a source of significant variation for tardigrades.</p>

Next generation sequencing technology and phylogenomics enhance the resolution of deep node phylogenies: A study of the Protostomia
… 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 their position in conjunction with signal dissection experiments to minimize systematic error. The origin …

Antarctic biodiversity surveys using high throughput sequencing: understanding landscape and communities of the Prince Charles Mountains.
… large spatial scales distribution of phyla Tardigrada and Arachnida and classes Enoplea (Nematoda) and Bdelloidea (Rotifera) in inland areas are constrained by terrain-age-related accumulation of salts, while other Classes (Chromadorea, Nematoda and Monogonata, Bdelloidea) are better able to …

The Observable Effects of Acetylcholine, Succinylcholine, D-tubocurarine and Quinine and Their Binary Combinations on Tardigrades
The problem. This study seeks to determine the observable effects of acetylcholine, 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 …

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 …
