New records of Mexican Tardigrada

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.

A checklist of Norwegian Tardigrada

Fauna Norvegica, 2017
Animals of the phylum Tardigrada are microscopical metazoans that seldom exceed 1 mm in length. They are recorded from terrestrial, limnic and marine habitats and they have a distribution from Arctic to Antarctica. Tardigrades are also named ‘water bears’

Area, depth and elevation of cryoconite holes in the Arctic do not influence Tardigrada densities

Polish Polar Research, 2016
Water bears (Tardigrada) are known as one of the most extremophile animals in the world. They inhabit environments from the deepest parts of the oceans up to the highest mountains.

Fossil freshwater fishes from the Pliocene of northern Colombia and the palaeogeography of northern South America

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Freshwater fishes from the northwestern Colombian Andes are reported from the Pliocene Sincelejo and Ware formations. A total of 10 taxa have been identified, involving two orders, five families and nine genera. Characters from dental morphology, fin spines and cranial bones are provided as taxonomic tools for the study of fossil fishes.

Aquatic tardigrades in Poland – a review

Limnological Review, 2021
The diversity, distribution and ecology of aquatic Tardigrada in Poland remain poorly known. We reviewed the literature focused on tardigrades in Poland and recognized only 15 aquatic taxa which were reported from various freshwater and marine habitats ...

At the Edge of Survival: Exploring the Frontiers of Tardigrade Extreme Stress Tolerance

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT Tardigrades possess extraordinary resilience to extreme environmental conditions, including near‐complete desiccation, severe levels of radiation, the vacuum of space and extreme sub‐zero temperatures. Despite significant interest in their survival strategies, the molecular mechanisms underlying their survival during extreme stresses have ...

Contribution to the fresh water Tardigrada from Barentsøya, Svalbard (78°30'N)

Fauna Norvegica, 1991
Fifteen species and one subspecies of Tardigrada were found in the littoral zone of 18 fresh water bodies on the Talaveraflya. All taxa are new records for Barentsøya; Hypsibius antarcticus and Macrobiotus dianeae were not previously reported from ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

An Integrated Assessment of European Soil Health and Restoration Potential

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Soils host a significant proportion of biodiversity on Earth providing ecosystem functions vital to human well‐being, making it imperative to include them and their ecological features when addressing sustainability goals. We performed a comprehensive assessment of soil health across Europe by explicitly integrating biotic and abiotic ...
