Macroalgal Biofilm Harbours a Wide Diversity of Parasitic Protists With Distinct Temporal Dynamics

Molecular Ecology, Volume 34, Issue 5, March 2025.
ABSTRACT Marine macroalgae surfaces create a nutrient‐rich environment that promotes the formation of epiphyte biofilms. Biofilms are complex systems that facilitate ecological interactions within the community, yet parasitism remains largely unexplored.

Environmental Sequencing Fills the Gap Between Parasitic Haplosporidians and Free‐living Giant Amoebae

Journal of Eukaryotic Microbiology, 2018
Class Ascetosporea (Rhizaria; Endomyxa) comprises many parasites of invertebrates. Within this group, recent group‐specific environmental DNA (eDNA) studies have contributed to the establishment of the new order Mikrocytida, a new phylogeny and ...

The Ribosomal Operon Database: A Full‐Length rDNA Operon Database Derived From Genome Assemblies

Molecular Ecology Resources, Volume 25, Issue 1, January 2025.
ABSTRACT Current rDNA reference sequence databases are tailored towards shorter DNA markers, such as parts of the 16/18S marker or the internally transcribed spacer (ITS) region. However, due to advances in long‐read DNA sequencing technologies, longer stretches of the rDNA operon are increasingly used in environmental sequencing studies to increase ...

Detection and characterisation of haplosporidian parasites of the blue mussel Mytilus edulis, including description of the novel parasite Minchinia mytili n. sp.

Diseases of Aquatic Organisms, 2019
The edible mussel Mytilus edulis is a major aquaculture commodity in Europe, with 168000 t produced in 2015. A number of abundant, well characterised parasites of the species are known, though none are considered to cause significant mortality ...

Life cycle strategies in free‐living unicellular eukaryotes: Diversity, evolution, and current molecular tools to unravel the private life of microorganisms

Journal of Eukaryotic Microbiology, Volume 71, Issue 6, November/December 2024.
Abstract An astonishing range of morphologies and life strategies has arisen across the vast diversity of protists, allowing them to thrive in most environments. In model protists, like Tetrahymena, Dictyostelium, or Trypanosoma, life cycles involving multiple life stages with different morphologies have been well characterized.

Keystone predatory protists are associated closely with ammonia‐oxidizing microorganisms in an acidic Ultisol

Journal of Sustainable Agriculture and Environment, Volume 3, Issue 1, March 2024.
Abstract Predatory protists are widely recognized as critical biotic forces driving soil microbial communities, but their top‐down controls on ammonia‐oxidizing microorganisms (AOMs), the major players in nitrification, are largely unresolved. Here, we investigated the communities of predatory protists and their associations with AOMs using high ...

Kingdom Chromista and its eight phyla: a new synthesis emphasising periplastid protein targeting, cytoskeletal and periplastid evolution, and ancient divergences

Protoplasma, 2017
In 1981 I established kingdom Chromista, distinguished from Plantae because of its more complex chloroplast-associated membrane topology and rigid tubular multipartite ciliary hairs.

Pseudovampyrella gen. nov.: A genus of Vampyrella‐like protoplast extractors finds its place in the Leptophryidae

Journal of Eukaryotic Microbiology, Volume 71, Issue 1, January/February 2024.
Abstract Vampyrellid amoebae are predatory protists, which consume a variety of eukaryotic prey and inhabit freshwater, marine and terrestrial ecosystems. Although they have been known for almost 150 years, much of their diversity lacks an in‐depth characterization.

Rhizarian ‘Novel Clade 10’ Revealed as Abundant and Diverse Planktonic and Terrestrial Flagellates, including Aquavolon n. gen.

Journal of Eukaryotic Microbiology, 2018
Rhizarian ‘Novel Clade 10’ (NC10) is frequently detected by 18S rRNA gene sequencing studies in freshwater planktonic samples. We describe a new genus and two species of eukaryovorous biflagellate protists, Aquavolon hoantrani n. gen. n. sp.
