Phytoplankton-associated bacterial community composition and succession during toxic diatom bloom and non-bloom events

Frontiers in Microbiology, 2016
Pseudo-nitzschia blooms often occur in coastal and open ocean environments, sometimes leading to the production of the neurotoxin domoic acid that can cause severe negative impacts to higher trophic levels.

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

Marine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Assimilation of diazotrophic nitrogen into pelagic food webs. [PDF]

PLoS ONE, 2013
The fate of diazotrophic nitrogen (N(D)) fixed by planktonic cyanobacteria in pelagic food webs remains unresolved, particularly for toxic cyanophytes that are selectively avoided by most herbivorous zooplankton.

Quantifying the impact of submesoscale processes on the spring phytoplankton bloom in a turbulent upper ocean using a Lagrangian approach

Geophysical Research Letters, 2016
The spring phytoplankton bloom in the subpolar North Atlantic and the mechanisms controlling its evolution and onset have important consequences for marine ecosystems and carbon cycling.

Sixty Years of Sverdrup: A Retrospective of Progress in the Study of Phytoplankton Blooms [PDF]

Oceanography, 2014
One of the most dramatic large-scale features in the ocean is the seasonal greening of the North Atlantic in spring and summer due to the accumulation of phytoplankton biomass in the surface layer.

A seasonal diary of phytoplankton in the North Atlantic [PDF]

, 2014
In recent years new biological and physical controls have been suggested to drive phytoplankton bloom dynamics in the North Atlantic. A better understanding of the mechanisms driving primary production has potentially important implications for the ...

Identification of Phytoplankton Blooms under the Index of Inherent Optical Properties (IOP Index)

Proceedings, 2017
Phytoplankton blooms are sporadic events in time and isolated in space. This complex phenomenon is produced by a variety of both natural and anthropogenic causes.

Strong responses of Southern Ocean phytoplankton communities to volcanic ash [PDF]

, 2014
Volcanic eruptions have been hypothesized as an iron supply mechanism for phytoplankton blooms; however, little direct evidence of stimulatory responses has been obtained in the field.

Emiliania huxleyi and climate change: a genetic and biogeographic investigation of bloom dynamics for a key phytoplankton species in the global carbon cycle [PDF]

, 2010
Emiliania huxleyi is a ubiquitous coccolithophore present throughout the global ocean and capable of forming large blooms with significant effects on the global carbon cycle. Developing our understanding of E.

Links between Phenology of Large Phytoplankton and Fisheries in the Northern and Central Red Sea

Remote Sensing, 2021
Phytoplankton phenology and size structure are key ecological indicators that influence the survival and recruitment of higher trophic levels, marine food web structure, and biogeochemical cycling.
