Unprecedented slow growth and mortality of the rare colonial cyanobacterium, Nostoc zetterstedtii, in oligotrophic lakes
Unprecedented slow growth rare colonial cyanobacterium
2014/4/4
Centimeter-large colonies of Nostoc zetterstedtii from a Swedish oligotrophic lake had the lowest growth and
mortality rates of any studied temperate macrophyte. Annual growth rates at two shallow si...
Calcium carbonate precipitation induced by the growth of the marine cyanobacterium Trichodesmium

Interactions between changing pCO2 N2 fixation, Fe limitation in the marine unicellular cyanobacterium Crocosphaera
2014/4/21
We examined the physiological responses of steady-state iron (Fe)-replete and Fe-limited cultures of the biogeochemically critical marine unicellular diazotrophic cyanobacterium Crocosphaera at glacia...
Agent-based modeling of the complex life cycle of a cyanobacterium (Anabaena)ina shallow reservoir
Agent-based modeling complex life cycle cyanobacterium a shallow reservoir
2014/4/18
The cyanobacteriumAnabaena flos-aquaeand many other phytoplankton species have a complex life cycle that includes a resting stage (akinete). We present a new agent-based (also known as individual-base...
