Phosphorus Acquisition Strategies Among Phytoplankton and Free‐Living Bacterial Communities in the Baltic Proper

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Phosphorus is a key element for cellular functions and poses significant challenges for planktonic microbial communities under limited availability. Metagenomics highlighted that heterotrophic bacteria predominantly relied on phosphate scavenging while eukaryotic phytoplankton primarily utilized membrane remodelling to cope with limited phosphorus ...

Biosynthesis of Selenium Nanoparticles Supported on and within Diatomite through a Continuous Flow Method

Proceedings, 2020
Diatomite, also known as diatomaceous earth (DE), is a sedimentary rock formed by the deposition of shells of unicellular microscopic algae of the class Bacillariophyceae (diatoms). [...]

Effects of River Beads on Algal Nutrient Limitation Following Severe Wildfire

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Severe wildfires often increase inputs of nitrogen (N) and phosphorus (P) to streams, which can alter nutrient limitation and primary production of benthic algae. Changes in nutrient limitation, however, vary over space and time due to physical and biological factors.

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, Volume 62, Issue 2, Page 261-292, April 2026.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Unveiling Protist Composition and Diversity Patterns With eDNA Metabarcoding: Comparing Short‐ and Long‐Read Approaches

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Environmental DNA (eDNA) metabarcoding is widely used for biodiversity monitoring, but short‐read sequencing limits detailed taxonomic identification, especially for protists. In a comparison of short‐ and long‐read approaches in the Belgian North Sea, long‐read metabarcoding provided deeper taxonomic assignment under the applied workflows and improved

OnPliocaenicus costatus(Bacillariophyceae) in Lake El’gygytgyn, East Siberia [PDF]

European Journal of Phycology, 2006
Pliocaenicus is a small, mainly fossil diatom genus that only rarely occurs in modern freshwater environments in eastern Russia. The only extant taxon of this genus, Pliocaenicus costatus , was studied from phytoplankton samples collected in Lake El'gygytgyn, a deep, ultraoligotrophic and low-conductivity crater lake in East Siberia.

A Comparative Analysis of DNA Metabarcoding and Morphological Identification in Diatoms Reveals Similar Patterns of Environmental Response

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study compares the use of two universal molecular markers (COI and 18S rRNA) with morphological identification to evaluate patterns in diatom communities from high mountain mires. The results revealed a strong correspondence in beta diversity and environmental response across beta and alpha diversity. However, these molecular markers were found to

Network Component Analysis Can Identify Potential Axenisation Strategies Circumventing Antibiotic‐Use for Phototrophic Eukaryotic Microalgae

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Network component analysis of published axenisation methods reveals optimal, antibiotic‐free workflows for phototrophic eukaryotic microalgae. Distinct strategies are identified for diatoms, dinoflagellates, and green algae. Verification using microscopy, sequencing, and cell counting enhances reproducibility.
