Cyanobacteria and Cyanotoxins in Mediterranean Reservoirs: Ecological Variability, Risks and Implications for Water Quality Assessment

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.

Essential dietary fatty acids affect intraspecific competition in herbivorous zooplankton

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract The trophic transfer efficiency at the pelagic phytoplankton‐zooplankton interface is—among other factors—governed by the dietary availability of polyunsaturated fatty acids (PUFAs) to herbivorous zooplankton. As most zooplankton taxa cannot synthesize PUFAs de novo, the phytoplankton PUFA composition is crucial for the herbivores' fitness. As
