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

open access: yesEcological 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 ...

Thoughts on the evolution and ecological niche of diatoms

open access: yesEcological Monographs, 2021
. Diatoms are the most recent major algal lineage added to the geological record, appearing more than 200 million years ago. They are stramenopile protists resulting from a secondary endosymbiotic event that yielded the only photosynthetic protistan ...

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

open access: yesHeliyon, 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 ...

Characterizing the “fungal shunt”: Parasitic fungi on diatoms affect carbon flow and bacterial communities in aquatic microbial food webs

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2021
Significance Planktonic microorganisms interact with each other in multifarious ways, ultimately catalyzing the flow of carbon and energy in diverse aquatic environments.

Seasonal Compositions of Size-Fractionated Surface Phytoplankton Communities in the Yellow Sea

open access: yesJournal of Marine Science and Engineering, 2022
Little information on the phytoplankton community in the Yellow Sea (YS)—especially size-fractionated phytoplankton—is currently available, in comparison to the various physicochemical studies in the literature.

Phytoplankton of the northern coastal and shelf waters of the Yucatan Peninsula, southeastern Gulf of Mexico, Mexico [PDF]

open access: yesCheck List, 2013
Based on long-term monitoring (2001-2012) and four oceanographic cruises (2010-2012) in the coastal and shelf waters of the Yucatan Peninsula, SE Gulf of Mexico, a list of 306 strictly phytoplanktonic and tychoplanktonic species from 131 genera is ...

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

open access: yesArctic, 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

open access: yesEcological 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.

A Competitive Advantage of Middle-Sized Diatoms From Increasing Seawater CO2

open access: yesFrontiers in Microbiology, 2022
Diatoms, one of the most important phytoplankton groups, fulfill their carbon demand from seawater mainly by obtaining passively diffused carbon dioxide (CO2) and/or actively consuming intracellular energy to acquire bicarbonate (HCO3–).
