Extending monitoring with sediment archive approaches: Comparison of biomonitoring, metabarcoding, and biomarkers to assess past phytoplankton dynamics

open access: yesLimnology and Oceanography: Methods, Volume 23, Issue 8, Page 578-593, August 2025.
Abstract Sedimentary archives can provide valuable insights into the study of anthropogenic impacts on marine and limnic ecosystems over centennial and millennial timescales, potentially extending the temporal breadth of observation‐based biomonitoring.

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

open access: yesMolecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

Submersed Aquatic Vegetation Enhances Density and Diversity of Epifaunal Invertebrates Compared to Filamentous Mats in the Central Baltic Sea

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
This study evaluates the relative importance of Submersed Aquatic Vegetation (SAV) and filamentous mats in shaping epifaunal invertebrate communities in the central Baltic Sea. Our results showed that diversity, vertical structure, and biomass of SAV were all positively associated with higher total epifaunal abundance and greater abundance of ...

Regulatory Coordination of Photophysical, Photochemical, and Biochemical Reactions in the Photosynthesis of Land Plants

open access: yesPlant Direct, Volume 9, Issue 5, May 2025.
ABSTRACT Balance among the sequential photophysical, photochemical, and biochemical reactions of photosynthesis is needed for converting fleeting energy in light to stable energy in chemical bonds. Any imbalance acts as either a bottleneck for limiting photosynthetic efficiency or an agent for inducing structural and functional damage to photosynthetic

Geomorphic consequences of freshwater discharge and microbial mats in a macrotidal environment: The case of the beach of Dannes (northern France)

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
This transdisciplinary study analyses the geomorphic consequences of microbial mats associated with freshwater outflows in a macrotidal environment. Microorganisms were identified using the DNA metabarcoding approach. SEM analysis of quartz collected from the beach surface provided data on the marine and aeolian forces, as well as biological processes ...

Comparison of Relative and Absolute Abundance and Biomass of Freshwater Phytoplankton Taxa Using Metabarcoding and Microscopy

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
In this study, 18S rRNA metabarcoding and microscopy revealed that the dynamics of relative and absolute abundance/biomass of phytoplankton taxa (classes, genera/species) are consistent in the southern basin of Lake Baikal in spring over 3 years. Absolute abundance/biomass of taxa (ASV, amplicon sequence variants) was obtained by combining relative ...
