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.
