Impacts of hypoxia on the mesozooplankton community structure in a semi-enclosed bay

Frontiers in Marine Science, 2022
Gamak Bay is frequently affected by hypoxia in summer. Therefore, this study aimed to examine the effect of hypoxia on the mesozooplankton community of this region. Mesozooplankton samples were obtained biweekly (28 times) at a hypoxic station (inner bay)

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

Freshwater 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.

A preliminary study on the feeding regime of European pilchard (Sardina pilchardus Walbaum 1792) in Izmir Bay, Turkey, Eastern Aegean Sea [PDF]

, 2005
The gut contents of Sardina pilchardus specimens captured in Izmir Bay were examined in order to determine their feeding regimes. Of the 365 stomachs examined, 321 (87.95%) contained food and 44 (12.05%) were empty. Analysis of gut contents verified that

Postglacial expansion of the arctic keystone copepod calanus glacialis [PDF]

, 2018
Calanus glacialis, a major contributor to zooplankton biomass in the Arctic shelf seas, is a key link between primary production and higher trophic levels that may be sensitive to climate warming. The aim of this study was to explore genetic variation in

Shared and Unique Patterns of Genomic Differentiation and Introgression Between Japanese Stickleback Species Across Three Sympatric Sites

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Hybridization and introgression frequently occur even between distantly related species. A central question in speciation research is which genomic regions act as barriers to gene flow and how genome‐wide differentiation persists despite hybridization between species.

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.
