Occurrence of toxin-producing cyanobacteria blooms in a Brazilian semiarid reservoir

Brazilian Journal of Biology
We report the occurrence of cyanobacterial blooms and the presence of cyanotoxins in water samples from the Armando Ribeiro Gonçalves reservoir (06° 08’ S and 37° 07’ W), located in the state of Rio Grande do Norte, in the semiarid region of northeastern

eDNA Metabarcoding Reveals Microbial Community Composition in Tropical Mangrove Forests in Makassar, Indonesia

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This study used environmental DNA (eDNA) metabarcoding with 18S rRNA markers to assess microbial diversity in the Lantebung Mangrove Forest, Makassar, Indonesia. It identified 103 microbial species across five kingdoms, revealing higher species richness in open‐water areas (P1) and greater individual abundance under mangrove canopy (P2).

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
