Diversity and Abundance of Phytoplankton in the Coastal Waters of South Sulawesi

open access: yesHayati Journal of Biosciences, 2021
Phytoplankton are primary producers that can be used as seawater condition indicators. Certain phytoplankton can proliferate, causing harmful algal blooms (HABs).

Assessment of the Effect of Atrazine on Soil Algal Flora in Sudan

open access: yesApplied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Atrazine is an environmentally persistent herbicide of global concern due to its low biodegradability in soil and its high potential to contaminate surface water and groundwater. This study investigated the effects of atrazine on soil algal communities under different soil types, temperature regimes, and nutrient amendments.

Four novel taxa of cyanobacteria from a unique thermal cave habitat in Vromoner Canyon, Albania

open access: yesJournal of Phycology, Volume 61, Issue 5, Page 1394-1422, October 2025.
Abstract Thermal and cave habitats on nearly all continents have been a substantial source of new cyanobacterial genotypes and morphotypes that expanded with the dawn of the era of molecular phylogenetics. In this study, we investigated the cyanobacterial flora of an extreme habitat of recently discovered caves with sulfur‐rich thermal springs, using ...

The role of light quality and species richness in shaping phytoplankton communities

open access: yesLimnology and Oceanography, Volume 70, Issue 8, Page 2097-2108, August 2025.
Abstract In natural water bodies, the light spectrum changes with depth, often toward a higher proportion of blue light. While spectral niche partitioning and functional redundancy are important concepts, our understanding of how light spectrum changes affect phytoplankton communities is limited.
