New records of Mexican Tardigrada Nuevos registros de Tardigrada mexicanos

Revista Mexicana de Biodiversidad, 2011
In 9 moss samples collected from Mexico, 6 tardigrade species, including 4 new records for the country, were found. The new records raise the number of known Mexican water bear species to forty-one.

Freshwater tardigrades from Hopen, Svalbard (76°31'N)

Fauna Norvegica
Seventeen species of Tardigrada were found in submerged mosses of 17 freshwater bodies from the SE part of the island of Hopen (Svalbard). Fourteen species are new records for Hopen; Pseudechiniscus islandicus was not previously reported from Svalbard ...

Enhancing metabarcoding efficiency and ecological insights through integrated taxonomy and DNA reference barcoding: A case study on beach meiofauna

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 ...

Developmental and genomic insight into the origin of the tardigrade body plan

Evolution &Development, Volume 26, Issue 4, July 2024.
Three hypotheses for the homology of tardigrade segments to segments of other panarthropods. H, tardigrade head; T1‐T4, tardigrade trunk segment 1–trunk segment 4. Abstract Tardigrada is an ancient lineage of miniaturized animals. As an outgroup of the well‐studied Arthropoda and Onychophora, studies of tardigrades hold the potential to reveal ...

A new, simplified, drying protocol to prepare tardigrades for scanning electron microscopy

Microscopy Research and Technique, Volume 87, Issue 4, Page 716-726, April 2024.
Here a cheap, safe, and fast new method for Tardigrada preparation for scanning electron microscope (SEM) is proposed. The new protocol allows to minimize the number of animals sacrificed for SEM studies and is potentially applicable to the study of other meiofaunal soft‐bodied taxa.

Integrative description of a new Pseudechiniscus species and a new population of Barbaria ganczareki (Michalczyk and Kaczmarek, 2007) (Heterotardigrada: echiniscidae) from Ecuador

The European Zoological Journal
The terrestrial genera Barbaria (13 taxa) and Pseudechiniscus (54 taxa) belong to the family Echiniscidae (Heterotardigrada). In two samples collected in the Cotachi-Caypas Ecological Reserve, specimens of both genera were found.
