Effect of sulfate availability on phytoplankton stoichiometry

open access: yesJournal of Phycology, Volume 61, Issue 4, Page 895-910, August 2025.
Abstract Sulfur (S) is a key element in multiple metabolic pathways of phytoplankton cells. The effect of S availability on phytoplankton elemental quotas and stoichiometry has been addressed in few studies, using a limited number of species and with contradictory results.

Volatile Compounds of the Cyanophyceae – A Review

open access: yesWater Science and Technology, 1983
A relationship between blue-green algae and off-flavours in water was reported as early as 1883. Continuing research has shown that two metabolites, geosmin and methylisoborneol are major contributors to unpalatable flavours in water and aquatic organisms.

Buffer Zone Degradation and Plankton Dynamics in Northern and Northeastern Parts of Lake Tana, Ethiopia: Implications for a Tropical Highland Lake Ecosystem

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Lake Tana, a UNESCO World Biosphere Reserve Lake. The lake contains 50% of Ethiopia's freshwater and fertile land, which favoured urbanization, agriculture and irrigation, impacting its ecosystem. Understanding the effects of buffer zone degradation on plankton and water quality was vital for sustainable resource utilization.

A Biosynthetic and Taxonomic Atlas of the Global Lichen Holobiont

open access: yesEnvironmental Microbiology, Volume 27, Issue 6, June 2025.
This analysis of 794 publicly available lichen shotgun metagenomic datasets, covering 467 unique lichen species from 34 countries, revealed that lichens are complex holobionts. They harbour a variety of fungal, algal, and bacterial players with remarkable biosynthetic capabilities.
