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.

Evaluation of sampling methods for periphytic fauna in macrophytes at the Espinhaço Mountain Range Biosphere Reserve, Minas Gerais State, Brazil = Avaliação dos métodos de amostragem para fauna perifítica em macrófitas na Reserva da Biosfera, Serra do Espinhaço, Estado de Minas Gerais, Brasil

Acta Scientiarum: Biological Sciences, 2008
The methods “Jar”, “Manual Removal” and “modified Ekman Dredge” wereevaluated for sampling periphyton fauna associated with aquatic macrophytes. Sixty-three samples were collected from five lentic and three lotic water bodies at the Espinhaço Mountain ...

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.

Characterising Soil Eukaryotic Diversity From NEON Metagenomics Datasets

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Belowground eukaryotic diversity serves a vital role in soil ecosystem functioning, yet the composition, structure, and macroecology of these communities are significantly under‐characterized. The National Ecological Observatory Network (NEON) provides publicly available datasets from long‐term surveillance of numerous taxa and ecosystem ...

Moss‐Accumulated eDNA Is a Promising Source for Terrestrial Biodiversity Surveys Across the Tree of Life and Biomes

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Developments in the environmental DNA (eDNA) field have revolutionised our ability to map biodiversity by providing cost‐effective and non‐invasive means to survey organisms across the tree of life. In the terrestrial realm, a variety of eDNA sources have been employed, but we lack easily accessible and cosmopolitan sources of terrestrial eDNA.

Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.

The deep sea elements of the Faroe Bank tardigrade fauna with a description of two new species

Journal of Limnology, 2007
Two new marine Tardigrada species are described from the calcareous sediments at the steep slope of the Faroe Bank in the North Atlantic Ocean. Parmursa torquata sp. nov. can be distinguished mainly by small cylindrical secondary clavae, and the presence

DNA Metabarcoding Reveals Tardigrades' Diversity and Dispersal Patterns in European Freshwater Rock Pools

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Freshwater rock pools are ephemeral and fragile habitats that support specialised animal taxa. While distributed worldwide, these habitats are usually neglected and overlooked. We used DNA metabarcoding and metaphylogeographic approaches to study inter and intraspecific tardigrade biodiversity to identify their biogeographic patterns to ...

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.
