3-Dimensional reconstruction of fluorescent structures in tardigrades

Journal of Limnology, 2007
Tardigrades are microscopic animals, thus brightfield microscopy is a well established method for tardigrade observation. Modern techniques in functional genetics like fluorescence in situ hybridisation or fluorescently labelled expression markers demand

Impacts of Land Use and Flood Regime on Zooplankton Egg Banks in a Large River Floodplain

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Zooplankton egg banks are crucial in rebuilding zooplankton populations in temporary water bodies when favourable conditions return after dry periods. However, their abundance, viability, and hatching success depend on many factors, with changes in land use and flooding regimes being potentially crucial drivers.

Nearctic freshwater tardigrades: a review

Journal of Limnology, 2007
The distribution and ecology of limno-terrestrial Tardigrada in the Nearctic realm remain poorly known. This is especially true of freshwater tardigrades (i.e., species found in permanently submerged habitats), which have received much less attention ...

The Polymers of Life: Exploring Cellular Function Through Polymer Concepts

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Biomolecular phase separation reveals that a hidden layer of cellular organization is governed by the principles of polymer science. This review bridges polymer physics and cell biology, offering a primer on fundamental concepts, proposing a framework for interrogating cellular function, and synthesizing biophysical methods for decoding macromolecular ...

Species richness of soil and leaf litter tardigrades in the Great Smoky Mountains National Park (North Carolina/Tennessee, USA)

Journal of Limnology, 2013
A large database now exists for tardigrades in the Great Smoky Mountains National Park (GSMNP) consisting of 780 samples, 15,618 specimens, and 80 species including 14 new to science. We found 43 species of tardigrades in 150 soil/leaf litter samples. We

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.

Biophysics of Tardigrade Survival [PDF]

Biophysical Journal, 2016
Tardigrades, commonly known as water bears, are microorganisms that can survive extreme conditions: temperatures from −274°C to 151°C, pressures from 0 to 6,000 atmospheres, 1,000 times more radiation than the average animal, 10 days in space and over 20 years of dehydration.

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 ...

Tardigrades of North America: Additions to Montana’s Biodiversity Including a New Species, Platicrista loloensis nov. sp. (Parachela, Hypsibioidea, Itaquasconinae)

Diversity
A total of 205 tardigrades representing two orders, five families, nine genera and ten species were extracted from a moss sample (104 tardigrades) and a lichen sample (101 tardigrades) collected near Missoula, Montana, in 2016.

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

Ecography, 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.
