Coral diseases in aquaria and in nature [PDF]

open access: yes, 2013
Many reef coral diseases have been described affecting corals in the wild, several of which have been associated with causal agents based on experimental inoculation and testing of Koch’s postulates.

Dead or Alive? Challenges in Discriminating Dietary From Host‐Associated Community via RNA and DNA Metabarcoding in a Filter Feeder

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
The present manuscript uses time series of highly standardized samples of a freshwater and a marine mussel from Germany to explore chances and challenges of identifying their associated community composition by a parallel DNA and RNA metabarcoding approach.

Flagellated endosymbiotic bacteria in a marine Frontonia sp. (Oligohymenophorea, Peniculida)

open access: yesProtistology, 2001
Frontonia sp. was repeatedly found in sea water samples collected from a shore near Leghorn (Ligurian sea). Endosymbiotic rod shaped bacteria 5-6 μm long were found in the cytoplasm of each Frontonia sp. specimen examined at the fluorescent microscope following DAPI staining procedure.

Candidatus Sonnebornia yantaiensis, a member of candidate division OD1, as intracellular bacteria of the ciliated protist Paramecium bursaria (Ciliophora, Oligohymenophorea) [PDF]

open access: yes, 2014
An intracellular bacterium was discovered in an isolate of Paramecium bursaria from a freshwater pond in Yantai, China. The bacteria were abundant and exclusively found in the cytoplasm of the host which, along with the green alga Chlorella, formed a ...

Comparative Studies on the Polymorphism and Copy Number Variation of mtSSU rDNA in Ciliates (Protista, Ciliophora): Implications for Phylogenetic, Environmental, and Ecological Research [PDF]

open access: yes, 2020
While nuclear small subunit ribosomal DNA (nSSU rDNA) is the most commonly‐used gene marker in studying phylogeny, ecology, abundance, and biodiversity of microbial eukaryotes, mitochondrial small subunit ribosomal DNA (mtSSU rDNA) provides an ...

Metabarcoding Unveils the Diversity and Dynamics of In Situ Diet and Symbionts Associated With Copepods in Chinese Coastal Waters

open access: yesDiversity and Distributions, Volume 31, Issue 6, June 2025.
ABSTRACT Aim Copepods are the key secondary producers in marine ecosystems, yet their in situ diet and symbionts remain underexplored due to technical challenges, limiting our understanding of their population dynamics and ecological functions. Using DNA metabarcoding, we jointly characterised the natural diet and symbionts of copepods across Chinese ...

Adaptation of Marine Heterotrophic Protists to Long‐Term Warming Selection

open access: yesGlobal Change Biology, Volume 31, Issue 6, June 2025.
Our study unraveled profitable adaptations of marine protozoa to long‐term warming. The optimal temperature, maximum growth rates, cell homeostasis, and cell size significantly increased after warming adaptation, suggesting a resilient future for this functional group.
