Ecology and Evolution, Volume 16, Issue 3, March 2026.Environmental DNA (eDNA) metabarcoding is widely used for biodiversity monitoring, but short‐read sequencing limits detailed taxonomic identification, especially for protists. In a comparison of short‐ and long‐read approaches in the Belgian North Sea, long‐read metabarcoding provided deeper taxonomic assignment under the applied workflows and improved

Ecology and Evolution, Volume 16, Issue 2, February 2026.This study compares the use of two universal molecular markers (COI and 18S rRNA) with morphological identification to evaluate patterns in diatom communities from high mountain mires. The results revealed a strong correspondence in beta diversity and environmental response across beta and alpha diversity. However, these molecular markers were found to

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.Network component analysis of published axenisation methods reveals optimal, antibiotic‐free workflows for phototrophic eukaryotic microalgae. Distinct strategies are identified for diatoms, dinoflagellates, and green algae. Verification using microscopy, sequencing, and cell counting enhances reproducibility.

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

Lista de microalgas epilíticas de la parte alta y media del río Gaira, Sierra Nevada de Santa Marta
Intropica, 2015 El fitoplancton es uno de los principales productores primarios en los sistemas acuáticos; sin embargo, en los ríos, gran parte de la comunidad de microalgas se encuentran adheridas a las rocas, lo que ayuda a conformar el perifiton.

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.
