Sampling Design and Sample Processing Affect Soil Biodiversity Assessments

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Biodiversity surveys require an appropriate sampling design for optimal performance and comparability across space and time and across studies. Based on PacBio and Illumina amplicon sequencing of animals, bacteria and fungi, we assessed and compared various soil sampling designs from widely used continental and global metabarcoding‐based ...

A new record of an interesting parasitic rotifer Balatro calvus Claparéde, 1867 in Hungary [PDF]

open access: yes, 2006
Although widely distributed the parasitic rotifer Balatro calvus CLAPARÉDE, 1867 has only been sporadically observed. Here we document the presence of this species in enchytraeid (Annelida) specimens from different regions of ...

Rich freshwater rotifer fauna of small lentic ecosystems of south Andaman, Andaman Sea, India (Rotifera: Eurotatoria) [PDF]

open access: yes, 2017
Small lentic ecosystems are hypothesized to be interesting habitats for metazoan diversity. This study is undertaken to document Rotifera of small freshwater bodies of south Andaman, India. A total of 11 2 species (S), belonging to 32 genera and

Hidden Waters, Unique Communities: Subterranean Zooplankton Beta Diversity in the Caatinga Drylands

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Subterranean waters are important but understudied biodiversity reservoirs, particularly in the semi‐arid Caatinga biome. We quantified the biological uniqueness of zooplankton communities in these groundwater‐dependent systems and investigated how environmental conditions shape beta diversity.

Effects of environmental factors on species diversity of rotifers using biodiversity indicators and canonical correlation analysis (CCA) [PDF]

open access: yesبوم‌شناسی آبزیان, 2017
Rotifers are microscopic aquatic animals of phylum Rotifera, live in a diverse range of aquatic habitats. They are important in ecology of freshwater ecosystems by recycling nutrients and can alter trophic dynamic of planktonic communities.

Faunistic analysis of freshwater zooplankton in small rock pools of Maritime Antarctica

open access: yesУкраїнський антарктичний журнал, 2022
Small water bodies like the rock pools are used as a model system for evolutionary and environmental studies with a growing interest. The zooplankton in the rock pools is a most interesting and promising research object.

Planktonic rotifers of a saline-lowland river : The Salado River (Argentina) [PDF]

open access: yes, 2002
Seasonal samples of zooplankton were taken during 1997-1999 at fifteen stations in the Salado River basin, and analysed in order to study the rotifer fauna. Spatio-temporal changes in the rotifer plankton composition were examined in the main channel and

Improved COI taxonomic assignment workflow enhances detection of invertebrates in environmental DNA

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 3, March 2026.
Abstract Environmental DNA (eDNA) metabarcoding is an increasingly popular and powerful tool in ecology, offering a non‐invasive method to assess biodiversity and monitor ecosystem health across diverse environments. While the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most widely used markers for studying eukaryotic ...

Does Long-Term Macrophyte Management in Lakes Affect Biotic Richness and Diversity? [PDF]

open access: yes, 2005
We hypothesize that the richness and diversity of the biota in Lake Moraine (42°50’47”N, 75°31’39”W) in New York have been negatively impacted by 60 years of macrophyte and algae management to control Eurasian watermilfoil ( Myriophyllum spicatum L.
