The impact of environmental factors on the phytoplankton communities in the Western Pacific Ocean: HPLC-CHEMTAX approach

open access: yesFrontiers in Marine Science, 2023
The distribution characteristics, biomass, and communities of phytoplankton in the western Pacific Ocean (WPO) were investigated using high-performance liquid chromatography (HPLC)-CHEMTAX analysis.

Effect of nutrient supply on cell size evolution of marine phytoplankton

open access: yesMathematical Biosciences and Engineering, 2023
The variation of nutrient supply not only leads to the differences in the phytoplankton biomass and primary productivity but also induces the long-term phenotypic evolution of phytoplankton.

Environmental Variables Outpace Biotic Interactions in Shaping a Phytoplankton Community

open access: yesDiversity
We evaluated the main environmental factors (abiotic and biotic) driving the phytoplankton community in a shallow tropical reservoir located in an environmentally protected area.

PMOT2023: A Large-Scale Multi-Object Tracking (MOT) Dataset with Application to Phytoplankton Observation

open access: yesJournal of Marine Science and Engineering, 2023
Phytoplankton play a critical role in marine food webs and biogeochemical cycles, and their abundance must be monitored to prevent disasters and improve the marine environment.

Characterization of plankton from the Galveston estuary [PDF]

open access: yes, 1992
The purpose of this report is to summarize the published studies on phytoplankton and zooplankton in the Galveston Estuary. Before this project had begun, it was determined that there was insufficient long term data on plankton in the Galveston Estuary ...

Fatty Acid Profiles and Production in Marine Phytoplankton

open access: yesMarine Drugs, 2019
Microalgae are the primary producers of carbon in marine ecosystems, fixing carbon and subsequently generating various biomolecules such as carbohydrates, proteins and lipids.

The Chemistry of Phytoplankton

open access: yesChemical Reviews
Phytoplankton have a high potential for CO2 capture and conversion. Besides being a vital food source at the base of oceanic and freshwater food webs, microalgae provide a critical platform for producing chemicals and consumer products. Enhanced nutrient levels, elevated CO2, and rising temperatures increase the frequency of algal blooms, which often ...

Initial size structure of natural phytoplankton communities determines the response to Daphnia diel vertical migration

open access: yesJournal of Limnology, 2012
Diel vertical migration (DVM) is a common behavior of many pelagic herbivorous zooplankton species in response to predation pressure. It is characterized by a twice daily habitat shift of the zooplankton species: staying in the epilimnion only during ...

Dynamics of a stochastic phytoplankton-toxin phytoplankton–zooplankton model [PDF]

open access: yesAdvances in Difference Equations, 2019
Abstract Environmental fluctuations and toxin-producing phytoplankton are crucial factors affecting marine ecosystems. In this paper, we propose a stochastic phytoplankton-toxin phytoplankton–zooplankton model to study the effect of environmental fluctuations on extinction and persistence of the population.

Towards a functional classification of the freshwater phytoplankton

open access: yes, 2002
This paper considers the structure of freshwater phytoplankton assemblages and promotes a scheme of vegetation recognition', based upon the functional associations of species represented in the plankton.
