Unravelling winter diatom blooms in temperate lakes using high frequency data and ecological modeling
temperate lakes winter diatom blooms winter phytoplankton ecological mode
2021/3/3
In temperate lakes, it is generally assumed that light rather than temperature constrains phytoplankton growth in winter. Rapid winter warming and increasing observations of winter blooms warrant more...
Coexisting in a Sea of Competition Similar Diatom Species Seek Out Nutrients in Different Ways
Diatom Species Seek Out Nutrients Different Ways
2015/4/13
Diversity of life abounds on Earth, and there's no need to look any farther than the ocean's surface for proof. There are over 200,000 species of phytoplankton alone, and all of those species of micro...

We introduce a trait-based description of diatom functional diversity to an existing plankton functional type (PFT) model, implemented for the eutrophied coastal ecosystem in the Southern Bight of the...
Research into diatoms commenced with the advent of the light microscope in the early 19th century and progressed to an advanced state in the 1950s. Since then the application of many new techniques, i...
Quantifying diatom aspirations: Mechanical properties of chain-forming species
Quantifying diatom aspirations Mechanical properties chain-forming species
2014/4/2
Diatoms developed a variety of mechanisms to form chain-like colonies, resulting in diverse morphologies and bulk mechanical properties. These properties affect translation, rotation, and deformation ...
Methionine synthase interreplacement in diatom cultures and communities: Implications for the persistence of B12 use by eukaryotic phytoplankton
Methionine synthase interreplacement diatom cultures communities: Implications persistence of B12 eukaryotic phytoplankton
2014/4/2
Three proteins related to vitamin B12 metabolism in diatoms were quantified via selected reaction monitoring mass spectrometry: B12-dependent and B12-independent methionine synthase (MetH, MetE) and a...
Iron and copper limitations differently affect growth rates and photosynthetic and physiological parameters of the marine diatom Pseudo-nitzschia delicatissima
Iron and copper limitations differently affect growth rates photosynthetic and physiological parameters marine diatom Pseudo-nitzschia delicatissima
2014/4/2
In ～ 50% of the ocean, iron (Fe) limits phytoplankton growth, including that of the diatom Pseudo-nitzschia. Fe-limited Pseudo-nitzschia spp. may produce the potent neurotoxin domoic acid (DA) to acce...
Accumulation of Gel Particles in the Sea-Surface Microlayer during an Experimental Study with the Diatom Thalassiosira weissflogii
Sea Surface Microlayer Extracellular Polymeric Substances
2013/1/11
Since the early 80’s, the sea-surface microlayer (SML) has been hypothesized as being a gelatinous film. Recent studies have confirmed this characteristic, which confers properties that mediate mass a...

Diatoms developed a variety of mechanisms to form chain-like colonies, resulting in diverse morphologies and bulk mechanical properties. These properties affect translation, rotation, and deformation ...
Application of PTR-MS to an incubation experiment of the marine diatom Thalassiosira pseudonana
dimethyl sulfide, isoprene, methanethiol
2011/4/12
Emission of trace gases from the marine diatom Thalassiosira pseudonana (CCMP1335) was continuously monitored
with a proton transfer reaction-mass spectrometry (PTR-MS) in an axenic batch culture sys...
Long-term pigment dynamics and diatom survival in dark sediment
Long-term pigment dynamic dark sediment
2011/4/8
In order to investigate survival of diatoms and long-term pigment dynamics in dark sediment, we incubated
samples of homogenized, sieved, tidal-flat sediment for 1 yr in darkness. Microscopic observa...
The path to preservation: Using proteomics to decipher the fate of diatom proteins during microbial degradation
The path to preservation: Using proteomics decipher the fate diatom proteins microbial degradation
2010/7/17
We drew upon recent advances in tandem mass spectrometry-based proteomic analyses in order to examine the proteins that remain after a diatom bloom enters the stationary phase, precipitates out of the...
Diatom sinking speeds: Improved predictions and insight from a modified Stokes’ law
mproved predictions insight
2010/4/17
Accurately predicting the size-dependant sinking rate of diatoms is necessary to fully understand the cycling of
oceanic carbon and silicon. Stokes’ law predicts that sinking velocity should be propo...
