Limnology and Oceanography, EarlyView.Abstract Harmful algal blooms caused by toxin‐producing species of the diatom genus Pseudo‐nitzschia have been linked to anomalously warm ocean conditions in the Northern California Current System. This study compares summertime concentrations of Pseudo‐nitzschia spp.

Limnology and Oceanography, EarlyView.Abstract Little is known about diatom parasitism in marine systems. Guinardia delicatula, a biomass‐dominant diatom on the Northeast US Shelf (NES), is regularly parasitized by the protistan nanoflagellate, Cryothecomonas aestivalis in this region. While G.

Invasion of a littoral cladoceran Sida crystallina into the pelagic zone of Christine Lake, NH and its potential impact on the phytoplankton community [PDF]
, 2011 This study evaluated the phytoplankton community and grazing influences of the zooplankton in oligotrophic Christine Lake, NH, by assessing the body size and clearance rates of the three dominant crustaceans: Sida crystallina (0.08 individuals L-1 ...

Manganese and the Growth of Phytoplankton [PDF]
Journal of the Marine Biological Association of the United Kingdom, 1947 Inshore water collected near Plymouth during the late summer and autumn of 1945, after enrichment with nitrate, phosphate and iron, did not support continued growth of a species of Chlamydomonas, of Chlorella, of a Cryptomonad and of two species of Chrysomonads.The addition of 0-5-2-0 mg.

Study of Phytoplankton Demographic Structure and Biodiversity and its Role in Aquaculture of the Golabar Dam Lake of Zanjan Province [PDF]
بومشناسی آبزیان, 2020 The purpose of this research was to determine the Phytoplankton communities, distribution, abundance, and diversity in Golabar dam lake of Zanjan province. Phytoplankton was sampled in 4 study stations during 1 year, from autumn 2009 to summer 2010.

Trait-based numerical model for mixotrophic phytoplankton and application in Singapore water [PDF]
arXiv, 2021 A numerical model for mixotrophic phytoplankton is described in this paper. In contrast with traditional approach where nutrient uptake rates are constrained by a predefined growth rate, this model uses empirical traits to compute nutrient uptake rates, and then the growth is controlled by the nutrient uptake.

Limnology and Oceanography, EarlyView.Abstract An autonomous Zooglider navigated across the California Current Front into low salinity, minty waters characteristic of the California Current proper in both summers of 2019 and 2021. Diving to 400 m depth, Zooglider transited another near‐surface frontal gradient somewhat inshore. These frontal gradients were generally associated with changes

Temporal and spatial variations in phytoplankton productivity in surface waters of a warm-temperate, monomictic lake in New Zealand [PDF]
, 2010 Surface phytoplankton productivity measurements were carried out in morphologically complex Lake Rotoiti with the objective of defining variations between sites and seasons, and the dominant environmental drivers of these variations.

Remote sensing of phytoplankton community composition in the northern Benguela upwelling system
Frontiers in Marine Science, 2023 Marine phytoplankton in the northern Benguela upwelling system (nBUS) serve as a food and energy source fuelling marine food webs at higher trophic levels and thereby support a lucrative fisheries industry that sustain local economies in Namibia ...

Does polymixis complicate prediction of high‐frequency dissolved oxygen in lakes and reservoirs?
Limnology and Oceanography, EarlyView.Abstract As lake and reservoir ecosystems transition across major environmental regimes (e.g., mixing regime) resulting from anthropogenic change, setting predictive expectations is imperative. We tested the hypothesis that (dissolved) oxygen is more predictable in monomictic reservoirs that thermally stratify throughout the summer (warm) season ...
