The Fundamental Role of Periphyton in Supplying Dietary Energy to Alpine Stream Food Webs: Current Knowledge, Limitations and Future Perspectives

Freshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT Periphyton is a key basal resource in stream food webs. It provides consumers with more easily digestible carbon than terrestrial resources, and is a major source of long‐chain polyunsaturated fatty acids (LC‐PUFA), which are essential for consumers.

Light and temperature acclimation of Rhodomonas salina (Cryptophyceae): photosynthetic performance [PDF]

Aquatic Microbial Ecology, 2002
Blooms of phototrophic cryptophytes have been observed in the highly eutrophic estuar- ine Darss-Zingst Bodden Chain (DZBC), Germany, during prolonged periods of light limitation due to ice and snow covering. The present study analyses possible mechanisms by which Rhodomonas salina, as a surrogate for bloom forming DZBC cryptophytes, maintains large ...

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

Environmental 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.

Large, double‐stranded DNA viruses tend to suppress phytoplankton populations more effectively than small viruses of diverse genome type

Limnology and Oceanography Letters, Volume 10, Issue 5, Page 745-753, September 2025.
Abstract Viruses infecting aquatic microbes vary immensely in size, but the ecological consequences of virus size are poorly understood. Here we used a unique suite of diverse phytoplankton strains and their viruses, all isolated from waters around Hawai'i, to assess whether virus size affects the suppression of host populations.
