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 ...

PRELIMINARY DATA ON TARDIGRADA FROM THE ARMENIAN FORESTED AREA

Bulletin of the Iraq Natural History Museum
Tardigrada is a phylum that has never been studied in Armenia, along with many other arthropod groups. Our research is about terrestrial tardigrade species. This study is the first paper on tardigrades from Armenia.

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.

Genome size variation in Tardigrada [PDF]

Zoological Journal of the Linnean Society, 1996
Abstract The genome size of tardigrades has been documented to date in seven species of eutardigrades, and it is among the lowest in invertebrates. In this paper the evaluation of genome size is extended to eight other species of eutardigrades and to one species of heterotardigrades, in order to obtain a more comprehensive picture of minimum DNA ...

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’

Two new species of Tardigrada from moss cushions (Grimmia sp.) in a xerothermic habitat in northeast Tennessee (USA, North America), with the first identification of males in the genus Viridiscus

PeerJ, 2020
Background The phylum Tardigrada consists of over 1,300 species that inhabit terrestrial, freshwater and marine environments throughout the world. In terrestrial habitats they live primarily in mosses, lichens, leaf litter and soil, whereas tardigrades ...

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.

Tardigrada of Xinjiang Uygur Autonomous Region, China

Journal of Limnology, 2007
Relatively little is known of the Tardigrada fauna of China, and there are no previous tardigrade records for Xinjiang Uygur Autonomous Region, China's largest administrative division. Moss specimens of the Missouri Botanical Garden Herbarium (St. Louis,

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.
