The genus Milnesium (Eutardigrada, Apochela, Milnesiidae) in Argentina: description of three new species and key to the species of South America

open access: yesEuropean Journal of Taxonomy, 2022
A revision of microscope slides deposited between 2014 and 2017 in the collection of Rocha and Doma (National University of La Pampa, Argentina) revealed three new species of the genus Milnesium Doyère, 1840: M. pelufforum sp. nov., M. irenae sp.

Soil nematode communities in grasslands [PDF]

open access: yes, 2007
This thesis summarizes the results of five studies investigating the effect of plant species on soil nematode communities in grasslands. Nematodes (roundworms) are ubiquitous members of the soil fauna and have been much used as indicators of soil ...

From niche theory to demographic realities: the demographic niche concept for understanding range‐wide population dynamics

open access: yesEcography, Volume 2026, Issue 5, May 2026.
The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

Chasing (macro)elements in microinvertebrates: A new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle‐Induced X‐Ray Emission) applied to glacier tardigrades

open access: yesMethods in Ecology and Evolution
Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence the turnover of macroelements. However, the investigation of their body elemental composition is complicated due to their low dry weight or sample ...

New insights into the limited thermotolerance of anhydrobiotic tardigrades

open access: yesCommunicative & Integrative Biology, 2020
The recent discovery of an upper limit in the tolerance of an extremotolerant tardigrade to high temperatures is astounding. Although these microinvertebrates are able to endure severe environmental conditions, including desiccation, freezing and high ...

Total RNA Extraction from Tardigrades [PDF]

open access: yesCold Spring Harbor Protocols, 2018
Purification of high-quality total RNA from specimens is essential for many molecular techniques. In tardigrades (water bears), disruption of the cuticle is an important step in obtaining a good yield that is representative of all tissues of the animal.

Arbuscular mycorrhizal fungal families and exploration‐based guilds exhibit distinct responses to long‐term N, P and K deficiencies and imbalances

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1846-1862, May 2026.
Summary Many agroecosystems face nitrogen (N), phosphorus (P) or potassium (K) deficiencies due to imbalanced or insufficient nutrient replenishment after biomass harvest. How this affects the symbiosis between plants and arbuscular mycorrhizal fungi (AMF) and the abundance of exploration‐based AMF guilds (rhizophilic, edaphophilic and ancestral ...

Comparative transcriptomics suggest unique molecular adaptations within tardigrade lineages

open access: yesBMC Genomics, 2019
Background Tardigrades are renowned for their ability to enter cryptobiosis (latent life) and endure extreme stress, including desiccation and freezing. Increased focus is on revealing molecular mechanisms underlying this tolerance.

Deciphering the Biological Enigma—Genomic Evolution Underlying Anhydrobiosis in the Phylum Tardigrada and the Chironomid Polypedilum vanderplanki

open access: yesInsects, 2022
Anhydrobiosis, an ametabolic dehydrated state triggered by water loss, is observed in several invertebrate lineages. Anhydrobiotes revive when rehydrated, and seem not to suffer the ultimately lethal cell damage that results from severe loss of water in ...

Microinjection of dsRNA in Tardigrades [PDF]

open access: yesCold Spring Harbor Protocols, 2018
Classical genetic analysis in the tardigrade Hypsibius exemplaris is a challenge because these animals are parthenogens. The publication of the H. exemplaris genome has facilitated the study of targeted genes by RNA interference (RNAi), a robust mechanism to disrupt gene function. This protocol describes microinjection of double-stranded RNA (dsRNA) in
