2014/4/4
We measured specific growth rates of Stephanodiscus minutulus, Nitzschia acicularis (diatoms), and Limnothrix redekei (cyanobacterium) under fluctuating and constant light in semi-continuous culture a...
Can photoinhibition control phytoplankton abundance in deeply mixed water columns of the Southern Ocean?

2014/4/17
To study how natural Southern Ocean phytoplankton communities acclimate to rapid fluctuations in irradiance levels that result from deep wind-driven mixing of the upper water column, we measured their...
Patterns in microphytobenthic primary productivity: Species-specific variation in migratory rhythms and photosynthesis in mixed-species biofilms

2014/5/9
The importance of temporal changes in the vertical distribution of microphytobenthic algae on the overall functioning of intertidal biofilms were investigated with low-temperature scanning electron mi...

2014/5/26
Negative effects of prey species on consumers could be due to deterrence, nutritional insufficiency, or toxicity of the prey. These effects can be discerned in experiments in which the suspect prey is...
What controls the mixed-layer depth in deep-sea sediments? The importance of POC flux

2014/5/26
The depth of biogenic particle mixing, i.e., the mixed-layer depth (L), is fundamental in models of organic-matter recycling and paleoreconstructions for deep-sea sediments. Factors postulated to cont...
Baltic Sea nitrogen fixation estimated from the summer increase in upper mixed layer total nitrogen

2014/6/9
We estimated nitrogen fixation from the increase in total nitrogen (N2 gas excluded) in the upper 20 m during the summer biomass increase of heterocystous filamentous cyanobacteria at the off-shore La...
