Identification and differentiation of Heterotardigrada and Eutardigrada species by riboprinting

Journal of Zoological Systematics and Evolutionary Research, 2007
In the last decades, the number of known tardigrade species has considerably increased to more than 960 species with new ones being discovered every year. However, the study of tardigrade species presents a general problem which is frequently encountered during the work with invertebrates: small size and remarkable degrees of phenotypic plasticity may ...

Tardigrada of Xinjiang Uygur Autonomous Region, China

Journal of Limnology, 2007
Relatively little is known of the Tardigrada fauna of China, and there are no previous tardigrade records for Xinjiang Uygur Autonomous Region, China's largest administrative division. Moss specimens of the Missouri Botanical Garden Herbarium (St. Louis,

Genetic diversity in the parthenogenetic reproducing tardigrade Echiniscus testudo (Heterotardigrada: Echiniscoidea)

Journal of Limnology, 2013
Little is known about the genetic structure of microscopic animals from mosses and lichens. A few studies have investigated the geographic variation in tardigrades from mosses, but so far no study has investigated the intra-population or local clonal ...

Community Analysis Reveals Biogeographical Patterns and Biodiversity Shortfalls in Antarctic Tardigrades

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

Tardigrades Research in Brazil: an overview and updated checklist

Arquivos de Zoologia, 2020
Tardigrades are microscopic animals, commonly referred to as “water bears”, and comprise the phylum Tardigrada. They are found in diverse habitats in terrestrial, freshwater and marine environments worldwide.

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 ...
