The Phanerozoic diversification of silica-cycling testate amoebae and its possible links to changes in terrestrial ecosystems [PDF]

open access: yes, 2015
The terrestrial cycling of Si is thought to have a large influence on the terrestrial and marine primary production, as well as the coupled biogeochemical cycles of Si and C.

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

open access: yesEcology 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

Clubroot Symptoms and Resting Spore Production in a Doubled Haploid Population of Oilseed Rape (Brassica napus) Are Controlled by Four Main QTLs

open access: yesFrontiers in Plant Science, 2020
Clubroot, caused by Plasmodiophora brassicae Woronin, is one of the most important diseases of oilseed rape (Brassica napus L.). The rapid erosion of monogenic resistance in clubroot-resistant (CR) varieties underscores the need to diversify resistance ...

Drivers and assemblies of soil eukaryotic microbes among different soil habitat types in a semi-arid mountain in China [PDF]

open access: yesPeerJ, 2018
The effects of environmental and species structure on soil eukaryotic microbes inhabiting semi-arid mountains remain unclear. Furthermore, whether community assembly differs in a variety of soil habitat types, for example, artificial forest, artificial ...

Cyanobacterial contribution to the genomes of the plastid-lacking protists [PDF]

open access: yes, 2009
Background Eukaryotic genes with cyanobacterial ancestry in plastid-lacking protists have been regarded as important evolutionary markers implicating the presence of plastids in the early evolution of eukaryotes.

Metabarcoding and biomass quantification reveal seasonal parasite associations in copepods

open access: yesLimnology 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.

A Novel Phytomyxean Parasite Associated with Galls on the Bull-Kelp Durvillaea antarctica (Chamisso) Hariot [PDF]

open access: yes, 2012
Durvillaea antarctica (Fucales, Phaeophyceae) is a large kelp of high ecological and economic significance in the Southern Hemisphere. In natural beds along the central coast of Chile (Pacific Ocean), abnormal growth characterized by evident gall ...

Phylogenetic analysis confirms the taxonomic placement of the marine flagellate Hermesinum adriaticum (Thecofilosea, Cercozoa, Rhizaria)

open access: yesJournal of Eukaryotic Microbiology, 2022
Hermesinum adriaticum is a rare marine and brackish flagellate that is of considerable interest due to its markable and fossilizable siliceous skeleton.
