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.

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 ...

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 ...

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 ...

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 ...

Comparative Amplicon and Shotgun Metagenome Profiling of Soil Microbial Communities in Kauri Forests Affected by Phytophthora agathidicida

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Soils beneath symptomatic and asymptomatic kauri trees were analysed using LAMP, amplicon sequencing, shotgun metagenomics, and PICRUSt2. LAMP detected Phytophthora agathidicida in 39/60 samples, while shotgun metagenomics detected it at low abundance across all samples.

Geographic Variation in the Diet of Red Knot (Calidris canutus) Chicks Reflects Local Prey Communities

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim To describe and compare the diets of an Arctic‐breeding shorebird, the Red Knot (Calidris canutus), across three geographically distinct breeding sites. We aimed to document the dietary patterns and identify key prey groups that characterise each population's foraging ecology.
