“…This is consistent with the larger thermal breadths and lower minimal thermal growth of diatoms when compared with cyanobacteria and dinoflagellates 48 . In contrast, diatom diversity follows a latitudinal gradient with a decrease in species richness towards the poles ( Figures 2c and S6c ), where diatom communities are likely hyper-dominated by a lower number of species, as observed in previous studies 49 .…”

Diatoms constitute one of the most diverse and ecologically important phytoplankton groups, yet their large-scale diversity patterns and drivers of abundance are unclear due to limited observations. Here, we utilizeTaraOceans molecular and morphological data, spanning pole to pole, to describe marine diatom diversity, abundance, and environmental adaptation and acclimation strategies. The dominance of diatoms among phytoplankton in terms of relative abundance and diversity was confirmed, and the most prevalent genera wereChaetoceros,Thalassiosira,ActinocyclusandPseudo-nitzschia. We defined 25 distinct diatom communities with varying environmental preferences illustrative of different life strategies. The Arctic Ocean stands out as a diatom hotspot with 6 of the diatom communities being exclusive to it. Light harvesting and photoprotection were among the cellular functions in which natural diatom populations invested the bulk of their transcriptional efforts. The biogeography of diatom lineages was consistent with their copy number for genes related to photoacclimation. This comprehensive study sheds light on marine diatom distributions, offering insights amid global change and oceanic anthropogenic impacts.

“…Latitudinal gradients can be stronger or weaker depending on the prevailing hydrographic and climatic conditions at a macroscale. (63) Therefore, these conditions should be considered as potential sources of divergence among different studies on the latitudinal diversity gradients (LDG) of diatoms.…”

This article delves into using benthic diatoms as bioindicators of water quality, focusing on their ability to detect eutrophication and pollution resulting from industrialization and urbanization. We systematically analyzed 1099 articles from databases such as Web of Science and Scopus using PRISMA methodology, evaluating the efficacy, role, utilities, limitations, and influence of environmental factors of diatoms. The results show variability in water quality monitoring methods, from multivariate analyses to formulas based on species abundance. We highlighted the need for adaptability and validation of specific indices such as IDP and DDI, principally due to limitations in their transregional applicability. In South America, only four countries have developed their methods for assessment using diatoms, while others still rely on international standards. This fact underlines the importance of implementing effective local policies to manage water resources. Finally, we concluded that diatoms are crucial biological indicators for monitoring aquatic ecosystems, although challenges such as complexity in taxonomic identification and lack of standardization condition their effectiveness. In addition, biogeographical and environmental factors play an essential role in the diversity of these species, being necessary for understanding and anticipating changes in aquatic environments.
