The Morphology, Ultrastructure and Molecular Phylogeny of a New Freshwater Heterolobose Amoeba Parafumarolamoeba stagnalis n. sp. (Vahlkampfiidae; Heterolobosea)

open access: yesDiversity, 2021
Heterolobose amoebae are important members of marine, freshwater, and soil microbial communities, but their diversity remains under-explored. We studied the diversity of Vahlkampfiidae to improve our understanding of heterolobosean relationships and ...

The Kaumoebavirus LCC10 Genome Reveals a Unique Gene Strand Bias among “Extended Asfarviridae

open access: yesViruses, 2021
Kaumoebavirus infects the amoeba Vermamoeba vermiformis and has recently been described as a distant relative of the African swine fever virus. To characterize the diversity and evolution of this novel viral genus, we report here on the isolation and ...

Database Release: PPSDB, a Linked Open Data Knowledge Base for Protist–Prokaryote Symbioses

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 6, November/December 2025.
ABSTRACT As the ecological and evolutionary importance of symbiotic interactions between protists (microbial eukaryotes) and prokaryotes (bacteria and archaea) is better appreciated, keeping an overview of their diversity and the literature becomes a growing and ongoing challenge.

The $Z$-invariant massive Laplacian on isoradial graphs

open access: yes, 2016
We introduce a one-parameter family of massive Laplacian operators $(\Delta^{m(k)})_{k\in[0,1)}$ defined on isoradial graphs, involving elliptic functions. We prove an explicit formula for the inverse of $\Delta^{m(k)}$, the massive Green function, which

Peritrichs (Ciliophora, Peritrichia) in the Danube: Keystone Organisms in the Formation of Diverse Protist Biofilms

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Colonial peritrichs act as physical ecosystem engineers in middle Danube biofilms, generating three‐dimensional structures during 1–28 days of colonisation. Their surfaces host filter feeder epibionts (choanoflagellates, other peritrichs, rotifers), expanding filtration capacity and promoting functional group establishment including swimming and ...
