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

Distribution and diversity of Tardigrada along altitudinal gradients in the Hornsund, Spitsbergen (Arctic) [PDF]

Polar Research, 2015
Two transects were established and sampled along altitudinal gradients on the slopes of Ariekammen (77°01′N; 15°31′E) and Rotjesfjellet (77°00′N; 15°22′E) in Hornsund, Spitsbergen.

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.

Integrative description of Macrobiotus anshui sp. nov. from the Madeira Island and new record of Macrobiotus dolosus Bertolani, Cesari, Giovannini, Rebecchi, Guidetti, Kaczmarek and Pilato, 2022 (Macrobiotidae; persimilis-polonicus complex) from England

The European Zoological Journal
Tardigrades from England and Madeira are poorly known and up to now only a few species of the genus Macrobiotus have been reported from both regions. In this paper we describe a new species, Macrobiotus anshui sp. nov.

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 ...

Phylogenetic position, validity and diversity of the genus Milnesioides (Eutardigrada: Apochela)

Zoological Journal of the Linnean Society, 2023
Abstract The order Apochela, the only exclusively carnivorous tardigrade lineage, comprises four genera, of which Milnesium contains multiple species and is common and cosmopolitan, whereas the remaining genera (Bergtrollus, Limmenius and Milnesioides) are monotypic, rare and have restricted geographical distributions.

Islands of ice: Glacier‐dwelling metazoans form regionally distinct populations despite extensive periods of deglaciation

Diversity and Distributions, Volume 30, Issue 10, October 2024.
Abstract Aim Glaciers cover considerable portion of land and host diverse life forms from single‐celled organisms to invertebrates. However, the determinants of diversity and community composition of these organisms remain underexplored. This study addresses the biogeography, population connectivity and dispersal of these organisms, especially critical
