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.

Metagenomic analysis of planktonic microbial consortia from a non-tidal urban-impacted segment of James River [PDF]

open access: yes, 2015
Knowledge of the diversity and ecological function of the microbial consortia of James River in Virginia, USA, is essential to developing a more complete understanding of the ecology of this model river system.

Horizontal gene transfer in bdelloid rotifers is ancient, ongoing and more frequent in species from desiccating habitats. [PDF]

open access: yes, 2015
BACKGROUND: Although prevalent in prokaryotes, horizontal gene transfer (HGT) is rarer in multicellular eukaryotes. Bdelloid rotifers are microscopic animals that contain a higher proportion of horizontally transferred, non-metazoan genes in their ...

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.

Whole-proteome tree of life suggests a deep burst of organism diversity. [PDF]

open access: yes, 2020
An organism tree of life (organism ToL) is a conceptual and metaphorical tree to capture a simplified narrative of the evolutionary course and kinship among the extant organisms.

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.

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.

Metabarcoding and metabolome analyses of copepod grazing reveal feeding preference and linkage to metabolite classes in dynamic microbial plankton communities [PDF]

open access: yes, 2016
In order to characterize copepod feeding in relation to microbial plankton community dynamics, we combined metabarcoding and metabolome analyses during a 22-day seawater mesocosm experiment.
