Expanding the taxonomic catalog of Brazilian meiofauna: diversity and distribution of the neglected phyla Tardigrada, Gastrotricha, and Kinorhyncha [PDF]

Zoologia (Curitiba)
Meiofauna is a guild of microscopic organisms (delimited by the mesh width of two sieves, upper 500 μm and lower 44 μm) that inhabit the sediment grains and periphyton of aquatic environments (both freshwater and marine).

First insights into female sperm storage duration in tardigrades

Ecology and Evolution, 2022
Female sperm storage is ubiquitous in the animal kingdom and it has been shown to be linked to several evolutionary processes, from postcopulatory sexual selection to dispersal.

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 ...

Analysis of Nematode Ventral Nerve Cords Suggests Multiple Instances of Evolutionary Changes to Neuron Number

Evolution &Development, Volume 28, Issue 2, June 2026.
“Analysis of Nematode Ventral Nerve Cords Suggests Multiple Instances of Evolutionary Addition and Loss of Neurons” Han et al. DAPI staining of Xiphinema sp. (Clade 2) highlighting the neuronal‐like nuclei within the ventral nerve cord. ABSTRACT Despite their diversity in habitats, nematodes are often considered to have a highly conserved neuroanatomy.

Scalable Benthic Biomonitoring: Trade‐Offs Between Bulk and Environmental DNA Metabarcoding Across Sediment Types

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Direct eDNA metabarcoding is the most scalable method for large benthic monitoring programs, provided that sampling effort is increased to compensate for slightly lower per‐sample biodiversity recovery. ABSTRACT DNA metabarcoding offers prospects to assess benthic biodiversity in a more scalable and comprehensive way, but processing methods remain ...

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.

Investigating Low‐Temperature Stress Responses in Crustacea Aquatic Species Through Comparative Transcriptomics

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Crustaceans, such as shrimp and crabs, are pivotal to global aquaculture, yet their productivity is severely impacted by low‐temperature stress. This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species ...

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’

Five animal phyla in glacier ice reveal unprecedented biodiversity in New Zealand's Southern Alps

Scientific Reports, 2021
Glacier ice is an extreme environment in which most animals cannot survive. Here we report the colonization of high elevation, climate-threatened glaciers along New Zealand’s southwestern coast by species of Arthropoda, Nematoda, Platyhelminthes ...
