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

Wolbachia in Antarctic terrestrial invertebrates: Absent or undiscovered?
Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.Endosymbiotic bacteria Wolbachia are recognized for their role in influencing host survival and stress resistance, particularly in cold environmental conditions across various species. However, our analysis of available data reveals a notable absence of Wolbachia in species abundant in the extreme cold conditions of Antarctica.

The 18S rDNA sequences support polyphyly of the Hypsibiidae (Eutardigrada)
Journal of Limnology, 2007 To extend data on 18S rDNA gene phylogeny within the Eutardigrada and to provide additional information on unclear taxonomic status of a glacier tardigrade Hypsibius klebelsbergi, gene sequences from seven tardigrade species of the family Hypsibiidae ...

Novel 12S mtDNA findings in sloths (Pilosa, Folivora) and anteaters (Pilosa, Vermilingua) suggest a true case of long branch attraction [PDF]
, 2008 We sequenced 12S RNA mtDNA for the majority of the extant species of sloths and anteaters and compared our results with previous data obtained by our group using 16S RNA mtDNA in the same specimens and to GenBank sequences of the extinct giant sloth ...

The Macrobiotus persimilis-polonicus complex (Eutardigrada, Macrobiotidae), another example of problematic species identification, with the description of four new species. [PDF]
, 2022 In the phylum Tardigrada, as in other meiofauna taxa, the small size of the animals and the paucity of morphological characters useful for taxonomy present a challenge for systematic studies.

Insights into the segmental identity of post-oral commissures and pharyngeal nerves in Onychophora based on retrograde fills [PDF]
, 2015 Scenario on the evolution of the arthropod brain. Animation, swf file. Anterior is up. The compound brain of arthropods (sensu Richter et al. [5]) most likely evolved by a fusion of initially separate proto-, deuto- and tritocerebral ganglia.

Molecular Ecology Resources, Volume 24, Issue 7, October 2024.Abstract Molecular techniques like metabarcoding, while promising for exploring diversity of communities, are often impeded by the lack of reference DNA sequences available for taxonomic annotation. Our study explores the benefits of combining targeted DNA barcoding and morphological taxonomy to improve metabarcoding efficiency, using beach meiofauna ...
