Bioaccumulation of Lanthanum by Two Strains of Marine Diatoms Nanofrustulum shiloi and Halamphora kolbei [PDF]

Biology
Bioaccumulation by diatoms, as the first stage of biomineralisation, has been widely studied for various metals, such as cadmium, copper, zinc, aluminium, gold, silver, etc. However, despite the fact that the mining and utilization of rare earth elements

Exploring diatom diversity through cultures - a case study from the Bow River, Canada

Journal of Limnology, 2022
Diatom cultures can help answer taxonomic, biogeographic and ecological questions on a local and global scale. Unialgal cultures are derived from a single cell and provide abundant material for morphological and molecular analyses.

Biomass and physiological responses of green algae and diatoms to nutrient availability differ between the presence and absence of macrophytes

Ecological Indicators, 2021
Nutrient enrichment commonly promotes phytoplankton biomass, while the presence of macrophytes can mitigate the promotion effects of nutrient loading. However, the existing studies have seldomly focused on the impacts of macrophytes on the phytoplankton ...

Phytoplankton composition and abundance as indicators of aquaculture effluents impact in coastal environments of mid Gulf of California

Heliyon, 2021
Composition and abundance of phytoplankton in two areas of Gulf of California, one near (ND) and one far (FD) from shrimp farms discharge, were studied in 3 seasons: late fall (farms finishing operations); spring (farms not operating); and summer (farms ...

Identification of the ecological preferences of Cyclotella comensis in mountain lakes of the northern European Alps

Arctic, Antarctic, and Alpine Research, 2020
Planktic diatom ecology in the mountain lakes of the northern European Alps has only been studied sparsely so far. To fill this knowledge gap, the driving parameters of planktic diatom assemblage composition in the euphotic zones of twenty lakes located ...

Differences in biodiversity and assembly mechanisms between planktonic and benthic diatom communities in riverine ecosystems: A case study in the Ashi river

Ecological Indicators, 2023
Diatoms are an indispensable component of river ecosystem biodiversity and play an important role in aquatic ecosystems. The community assembly mechanism of diatoms has always been a central issue in the study of aquatic ecology.
