Microcosm experiments reveal source‐specific impacts of atmospheric aerosols on plankton communities and organic matter in the sea surface microlayer

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The impact of atmospheric deposition on marine ecosystems requires consideration of the interfacial processes within the sea surface microlayer, the uppermost layer at the air–sea interface. This study examines the impact of anthropogenic and biomass burning aerosol particles on the plankton community structure and organic matter accumulation ...

Microbial Diversity of Pinnacle and Conical Microbial Mats in the Perennially Ice-Covered Lake Untersee, East Antarctica

Frontiers in Microbiology, 2020
Antarctic perennially ice-covered lakes provide a stable low-disturbance environment where complex microbially mediated structures can grow. Lake Untersee, an ultra-oligotrophic lake in East Antarctica, has the lake floor covered in benthic microbial mat

Shedding light on vampires: the phylogeny of vampyrellid amoebae revisited. [PDF]

PLoS ONE, 2012
With the advent of molecular phylogenetic techniques the polyphyly of naked filose amoebae has been proven. They are interspersed in several supergroups of eukaryotes and most of them already found their place within the tree of life.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, Volume 5, Issue 2, Page 177-191, May 2026.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

The vampyrellid amoeba Strigomyxa ruptor gen. et sp. nov. and its remarkable strategy to acquire algal cell contents

Ecology and Evolution
The vampire amoebae (Vampyrellida, Rhizaria) inhabit freshwater, marine, and terrestrial ecosystems and consume a wide range of eukaryotic prey. This includes diverse microalgae, fungi, and microscopic animals.

Metabarcoding and biomass quantification reveal seasonal parasite associations in copepods

Limnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract Parasites are important members of ecosystems, and recent metabarcoding efforts have revealed an abundance of microbial eukaryotic parasites in copepods. However, a putative linkage to host community biomass and composition has not been addressed. We performed zooplankton tows monthly for 2 yr at five stations in the Oslofjord, Norway.

Multi-marker eDNA metabarcoding reveals significant eukaryotic biodiversity gaps in the Gulf of Gdańsk, Southeastern Baltic Sea

Frontiers in Marine Science
As climate change and human pressures intensify, advancing our understanding of biodiversity and ecological shifts in vulnerable regions, such as the Baltic Sea, is becoming increasingly important.

Revealing the Physiological Patterns of Dinoflagellates in North‐Eastern Adriatic Phytoplankton

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Using metatranscriptomics, we have described the annual taxonomic and functional succession of the phytoplankton community in the north‐eastern Adriatic Sea, taking into account the effects of environmental factors on succession. The results obtained in this way represent the first comprehensive physiological characterisation of the phytoplankton ...

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.

Radiolaria divided into Polycystina and Spasmaria in combined 18S and 28S rDNA phylogeny.

PLoS ONE, 2011
Radiolarians are marine planktonic protists that belong to the eukaryote supergroup Rhizaria together with Foraminifera and Cercozoa. Radiolaria has traditionally been divided into four main groups based on morphological characters; i.e.
