Protist community composition during early phytoplankton blooms in the naturally iron-fertilized Kerguelen area (Southern Ocean) [PDF]

Biogeosciences, 2014
Microbial eukaryotic community composition was examined by 18S rRNA gene tag pyrosequencing, during the early phase of spring phytoplankton blooms induced by natural iron fertilization, off Kerguelen Island in the Southern Ocean (KEOPS2 cruise).

Dominance of Ciliophora and Chlorophyta Among Phyllosphere Protists of Solanaceous Plants

Phytobiomes Journal, 2023
Phyllosphere microbiota play an important role in shaping plant health and function but most research has focused only on bacterial and fungal communities. As a result, little is known about the composition of diverse microeukaryotes in the phyllosphere,

Environmental DNA metabarcoding reveals biodiversity recovery in tropical forest restoration across multiple landscapes

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract Forest ecosystems have been degraded globally and restoration efforts aim to reverse loss of biodiversity and ecosystem function decline including carbon storage from the atmosphere. Assessments of restoration success predominantly emphasize increasing carbon stocks rather than species recovery.

DNA metabarcoding reveal hidden diversity of periphytic eukaryotes on marine Antarctic macroalgae [PDF]

Anais da Academia Brasileira de Ciências
Polar marine macroalgae thrive in extreme conditions, often displaying geographic isolation and high degree of endemism. The “phycosphere” refers to the zone around the algae inhabited by microrganisms.

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...

“Candidatus Finniella” (Rickettsiales, Alphaproteobacteria), Novel Endosymbionts of Viridiraptorid Amoeboflagellates (Cercozoa, Rhizaria) [PDF]

Applied and Environmental Microbiology, 2016
ABSTRACT The Rickettsiales ( Alphaproteobacteria ) are obligate intracellular bacteria that colonize a wide range of eukaryotic hosts, including diverse metazoa and protists.

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

Genetic Diversity, Community Assembly, and Shaping Factors of Benthic Microbial Eukaryotes in Dongshan Bay, Southeast China

Frontiers in Microbiology, 2020
Microbial eukaryotes are pivotal components of marine ecosystems. However, compared with the pelagic environments, the diversity distribution and the driving mechanisms of microbial eukaryotes in the marine sediments have rarely been explored.

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

BioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...

Precipitation Modulates the Impact of Human Activities on Riverine Food Webs Revealed by Environmental DNA

Ecology and Evolution, Volume 16, Issue 6, June 2026.
The effects of human activities on ecological networks are associated with climate, with increased precipitation weakening their negative impact. ABSTRACT The functionality of global rivers has been adversely affected by environmental pollution and habitat degradation.
