Phytoplankton dynamics

open access: yesComptes Rendus. Biologies, 2004
We present a model of the phytoplankton dynamics. The distribution of the size of the phytoplankton aggregates is described by a non-linear transport equation that contains terms responsible for the growth of phytoplankton aggregates, their fragmentation and coagulation.

Phytoplankton Community Composition Determined From Co-variability Among Phytoplankton Pigments From the NAAMES Field Campaign

open access: yesFrontiers in Marine Science, 2020
Analysis of phytoplankton chemotaxonomic markers from high performance liquid chromatography (HPLC) pigment determination is a common approach for evaluating phytoplankton community structure from ocean samples.

Response of the Phytoplankton Sinking Rate to Community Structure and Environmental Factors in the Eastern Indian Ocean

open access: yesPlants, 2022
The phytoplankton sinking rate in the eastern Indian Ocean was measured during spring 2017 based on the SETCOL method. The range of phytoplankton sinking rates was −0.291 to 2.188 md−1, with an average of 0.420 ± 0.646 md−1.

Sustenance of phytoplankton in the subpolar North Atlantic during the winter through patchiness [PDF]

open access: yes, 2017
This study investigates the influence of two factors that change the mixed layer depth and can potentially contribute to the phytoplankton sustenance over winter: 1) variability of air-sea fluxes and 2) three-dimensional processes arising from strong ...

Effect of Polystyrene Microplastics in Different Diet Combinations on Survival, Growth and Reproduction Rates of the Water Flea (Daphnia magna)

open access: yesMicroplastics, 2022
Microplastic pollution is a problem not only in the marine environment but also in freshwater ecosystems. Water flea (Daphnia magna) is one of the most common omnivorous cladocerans in freshwater ecosystems.

Investigation of Dynamism of Phytoplankton Diversity and Distribution in Chabahar Bay (In Summer, Winter, Pre and Post Monsoon) [PDF]

open access: yesمحیط زیست و توسعه فرابخشی, 2021
The abundance, distribution, biodiversity and species composition of phytoplankton and the concentration of nutrient were evaluated in Chabahar Bay during 2018-2019.

Effect of large- and small- bodied zooplankton on phytoplankton in a eutrophic oxbow [PDF]

open access: yes, 2005
Macrozooplankton and microzooplankton effects on the phytoplankton were measured in situ in a eutrophic lake. Indigenous phytoplankton were incubated for 5 days in 301 mesocosms with either the macro- and microzooplankton (complete), microzooplankton ...

Combined Effect of Light and Temperature on the Production of Saxitoxins in Cylindrospermopsis raciborskii Strains

open access: yesToxins, 2019
Cylindrospermopsis raciborskii is a potentially toxic freshwater cyanobacterium that can tolerate a wide range of light and temperature. Due to climatic changes, the interaction between light and temperature is studied in aquatic systems, but no study ...

Local and regional determinants of phytoplankton communities in water reservoirs from the Cerrado biome

open access: yesActa Limnologica Brasiliensia, 2023
Aim Based on a study comprising water reservoirs within the Brazilian Cerrado biome, we seek to answer the following question: how does phytoplankton communities respond to environmental, landscape, and spatial predictors? We expected local predictors to

PIBM 1.0: an individual-based model for simulating phytoplankton acclimation, diversity, and evolution in the ocean [PDF]

open access: yesGeoscientific Model Development
Phytoplankton is a diverse group of photosynthetic organisms and accounts for almost half of global primary production. However, most existing marine ecosystem models incorporate limited phytoplankton diversity, overlook phytoplankton evolution, and ...
