Tales of the crown: An integrative approach to the testate amoeba Galeripora dentata (Ehrenberg, 1830) Siemensma, 2021 (Amoebozoa, Arcellinida, Arcellidae).

European Journal of Protistology
Species delimitation in unicellular organisms remains a significant challenge, primarily due to the limited number of taxonomically informative traits and their often adaptive nature.

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 ...

When ecological transitions are not so infrequent: independent colonizations of athalassohaline water bodies by Arcellidae (Arcellinida; Amoebozoa), with descriptions of four new species

FEMS Microbiology Ecology, 2023
The salinity and humidity barriers divide biodiversity and strongly influence the distribution of organisms. Crossing them opens the possibility for organisms to colonize new niches and diversify, but requires profound physiological adaptations and is ...

Differential Effects of Long‐Term Fertilization and Plant Species Richness on Soil Fungi and Protists

Global Change Biology, Volume 32, Issue 7, July 2026.
Fertilization strongly influences plant and soil biodiversity, yet it remains unclear whether fertilization alone drives shifts in soil biota (fungi and protists) or whether associated losses in plant diversity further intensify these effects. Moreover, it is unknown whether fertilization and plant diversity decline act through similar mechanisms or ...

A brief overview of freshwater species of naked amoebae genus Mayorella Schaeffer, 1926 (Amoebozoa; Discosea)

Visnik ukrains'kogo tovaristva genetikiv i selekcioneriv
Aim. Naked amoebae are widespread in water bodies and terrestrial biotopes. These organisms are difficult to reproduce in laboratory conditions and identify by morphological and genetic characteristics.

Pyrumthecina n. Infraord.: Revisiting the Morphological Diversity and Identifying the Phylogenetic Home of Argynnia Within Arcellinida (Tubulinea: Amoebozoa)

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Arcellinida is a diverse lineage of testate amoebae within Amoebozoa, whose evolutionary history has been clarified through phylogenomics, resulting in a stable classification into suborders and infraorders. Yet, some taxa, such as the genus Argynnia, remain unplaced due to ambiguous morphology and uncertain positions in single‐gene ...

Quaternary Ice Ages Shaped Protists Phylogeography: The Case of Arcellinida in the Iberian Peninsula

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT The Quaternary glaciations profoundly shaped the biogeography of plants and animals, yet their impact on microbial eukaryotes remains largely unexplored. We tested the “genetic legacy of the Quaternary” (GLQ) paradigm in terrestrial protists using Arcellinida testate amoebae diversity distribution across the Iberian Peninsula, a well ...
