Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

open access: yesFreshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.

The predatory feeding of Acanthocyclops viridis (Jur.) (Copepoda, Cyclopoida). [Translation from: Trudy Inst.Biol.Vodokhranil. 2(5) 117-127, 1959. ] [PDF]

open access: yes, 1959
The feeding of freshwater copepods, especially cyclopoida, has been poorly covered in research so far. The majority of existing special works on the feeding of cyclopoida illustrate this question only from the qualitative side.

Fatty Acids and Stomach Contents Reveal Dietary Overlaps of Two Prospering Squid Species in the North Sea

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Distribution ranges of cephalopods are expanding worldwide and their abundances are increasing due to ocean warming. Recently, the broadtail shortfin squid Illex coindetii (Ommastrephidae) expanded into the North Sea where it established a successful spawning stock beside the resident veined squid Loligo forbesii (Loliginidae). Stomach content analysis

Elevated carbon dioxide can boost freshwater zooplankton abundance, while warming may shift community composition, weakening phytoplankton control

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S273-S288, December 2025.
Abstract Zooplankton communities in ponds and lakes control phytoplankton growth and serve as a food source for higher trophic levels such as fish. Recent experiments have shown that several freshwater zooplankton species as well as the phytoplankton communities on which they feed can be variably affected by rising temperatures, reduced pH and higher ...
