Tardigrades Research in Brazil: an overview and updated checklist

open access: yesArquivos 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.

Suggested Involvement of PP1/PP2A Activity and De Novo Gene Expression in Anhydrobiotic Survival in a Tardigrade, Hypsibius dujardini, by Chemical Genetic Approach.

open access: yesPLoS ONE, 2015
Upon desiccation, some tardigrades enter an ametabolic dehydrated state called anhydrobiosis and can survive a desiccated environment in this state. For successful transition to anhydrobiosis, some anhydrobiotic tardigrades require pre-incubation under ...

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

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
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.

Tardigrades and Microscopes [PDF]

open access: yesMicroscopy Today, 2003
Abstract Commonly known as 'water bears', tardigrades are a phylum of microscopic animals that can be found living on mosses and lichens all over the world. The name Tardigrada means 'slow walker' which describes their sluggish, deliberate movements. Between these slow movements and their 'teddy bear' like appearance, tardigrades are the

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

open access: yesThe FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Extremely high abundances of Prasiola crispa-associated micrometazoans in East Antarctica

open access: yesPolar Research, 2022
To elucidate poorly known aspects of the microscopic metazoan distribution in ice-free parts of the Antarctic, we examined samples of the multicellular terrestrial alga Prasiola crispa, collected over the last decade in different parts of continental ...

Taxonomy, systematics and ecology of the phylum Tardigrada [PDF]

open access: yes, 2014
This thesis is based on published papers, however there have been issues encountered with copyright permissions, therefore a fuller version may be submitted in the future.I conducted a series of research programmes on various aspects of Tardigrada ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Tips and tricks how to culture water bears: simple protocols for culturing eutardigrades (Tardigrada) under laboratory conditions

open access: yesThe European Zoological Journal, 2021
Tardigrades are microinvertebrates inhabiting almost all aquatic and terrestrial ecosystems throughout the world. They are known for their ability to enter into cryptobiosis and to survive extreme environmental conditions (e.g.

An Integrated Assessment of European Soil Health and Restoration Potential

open access: yesJournal 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 ...
