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.

Biogeography of Micro-Eukaryotic Communities in Sediment of Thermokarst Lakes Are Jointly Controlled by Spatial, Climatic, and Physicochemical Factors Across the Qinghai-Tibet Plateau

Frontiers in Ecology and Evolution, 2022
Thermokarst lakes are formed following ice-rich permafrost thaw and widely distribute in the cold regions with high latitude and elevation. However, the micro-eukaryotic communities (MECs) in thermokarst lakes are not well studied.

Wetland biodiversity in Aotearoa New Zealand: an eDNA perspective on exotic and non‐exotic species

New Zealand Journal of Zoology, Volume 52, Issue 4, Page 410-427, December 2025.
ABSTRACT Invasive species threaten biodiversity in Aotearoa New Zealand. In wetlands − significant sites that provide an array of ecosystem and cultural services but represent <10% of their original extent − invasive species can affect hydrological function, nutrient regimes and overall ecological functionality.

New records of deep-sea Gastrotricha and Tardigrada from Iberian and Canary Basins (Northeast Atlantic) with comments on abyssal meiofauna composition and the meiofauna paradox

Вісник Харківського Національного Університету Імені В.Н. Каразіна: Серія Біологія
The “meiofauna paradox” refers to the amphi-oceanic or even cosmopolitan distribution of species of this ecological group, i.e. the marine meiofauna, as opposed to their weak dispersal potential.

Significant occurrence of Musellifer profundus Vivier, 1974 (Gastrotricha, Chaetonotida) in the Black Sea [PDF]

Check List, 2019
Specimens of the gastrotrich genus Musellifer are recorded for the first time from the Black Sea. These specimens, identified as M. profundus Vivier, 1974, were found in sediment samples collected at various depths (22&minus;135 m) and from waters ...

Fake Webs, Real Results: Artificial Spiderwebs for eDNA Collection

Environmental DNA, Volume 7, Issue 6, November–December 2025.
We designed artificial spiderwebs to see if they are as good as natural spiderwebs at capturing airborne DNA. In comparison to water eDNA methods, both natural and artificial spiderwebs revealed a distinct signature of terrestrial communities, while artificial webs served as a good proxy for natural webs ‐ without the negative impacts on spiders and ...

Dendrodasys duplus, a New Gastrotrich Species (Macrodasyida: Dactylopodolidae) from South Korea

Animal Systematics, Evolution and Diversity, 2014
A new gastrotrich species of the genus Dendrodasys (Dactylopodolidae) is described on the basis of specimens collected from sublittoral fine sandy bottoms at Uljin, East Sea and at Gujwa, the northeastern coast of Jeju Island, South Korea.

Macroecological and Biogeographic Patterns of Kinorhyncha in the Iberian Peninsula

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Biogeography and macroecology aim to understand the processes that determine patterns in nature. In the marine environment, most of what we know has been documented for fish and macrobenthic organisms. As a result, this knowledge is negatively biased towards smaller benthic organisms, including meiofauna.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

Characterizing Rocky Intertidal Biodiversity Using Environmental DNA Metabarcoding From Local to National Scales

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We assess the resolution of eDNA metabarcoding for detecting rocky intertidal taxa across three spatial scales—national, regional, and local. Distinct eDNA signals were observed at each scale, with community differences more pronounced at broader scales.
