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

open access: yesFreshwater 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.

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

open access: yesNew 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.

A huge undescribed diversity of the subgenus Hystricochaetonotus (Gastrotricha, Chaetonotidae, Chaetonotus) in Central Europe

open access: yesEuropean Journal of Taxonomy, 2022
The subgenus Hystricochaetonotus Schwank, 1990 is one of the most species-rich subgenera of Chaetonotus Ehrenberg, 1830. It has a worldwide distribution and encompasses 37 species predominantly living in the benthos and periphyton of limnetic habitats ...

Fake Webs, Real Results: Artificial Spiderwebs for eDNA Collection

open access: yesEnvironmental 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 ...

Freshwater Gastrotricha of Poland. I. Gastrotricha from the Tatra and Karkonosze Mountains [PDF]

open access: yesFragmenta Faunistica, 1986
Res\ilts of the research on gastrotrichan fauna of the Tatra and Karkonosze Moun­ tains. 39 species were recorded, solely of the fam ily Chaetonotidae. Out of the identified 33 species, 3 species (Chaetonotus sudeticus, Aspidiophorus tatraensis and A. tetrachaetus) are new' to science, Ch. formosus is new to the fauna of Europe, w hile Ch.

Macroecological and Biogeographic Patterns of Kinorhyncha in the Iberian Peninsula

open access: yesJournal 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

open access: yesMethods 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.

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

open access: yesFrontiers 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.

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

open access: yesEnvironmental 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.
