CO2 concentrating mechanisms in algae: mechanisms, environmental modulation, and evolution.
The diversity of CCMs, their evolutionary origins, and the role of the environment can exert regulatory effects on the expression of the CCM components are discussed.
The Evolution of Modern Eukaryotic Phytoplankton
The geological, geochemical, and biological processes that contributed to the rise of the dinoflagellates, coccolithophores, and diatoms all contain plastids derived from an ancestral red alga by secondary symbiosis are examined.
Plant nutrient-acquisition strategies change with soil age.
Phytoplankton in a changing world: cell size and elemental stoichiometry
It is suggested that cell size and elemental stoichiometry are promising ecophysiological traits for modelling and tracking changes in phytoplankton community structure in response to climate change.
Ocean acidification due to increasing atmospheric carbon dioxide
The oceans cover over two-thirds of the Earth’s surface. They play a vital role in global biogeochemical cycles, contribute enormously to the planet’s biodiversity and provide a livelihood for…
The 15N natural abundance (d15N) of ecosystem samples reflects measures of water availability
Global and seasonal data are presented, a proximate mechanism for the overall relationship between water availability and ecosystem delta(15)N is postulated and, newly, a mechanism accounting for the highly delta( 15)N-depleted values found in the foliage and soils of many wet/cold ecosystems is proposed.
Temperature and algal growth
Genotypic variation in the temperature optimum for resource-saturated growth of microalgae has been used to provide envelopes of μm (maximum specific growth rate) as a function of temperature to suggest that, at their temperature optima, the cells are close to their maximum potential growth rate, based on the known kinetic properties of their catalysts.

A number of lines of evidence suggest the intrinsic PSi(OH)4 of about 10‐10 m s‐1 in the plant cell plasmalemma, while relatively low, could maintain the intracellular concentration of Si( OH)4 equal to that in the medium for a phytoplankton cell of 5 μm radius growing with a generation time of 24 h.
ADAPTATION OF UNICELLULAR ALGAE TO IRRADIANCE: AN ANALYSIS OF STRATEGIES
Comparison of the photon flux densities at which photoinhibition occurs in dinoflagellates and diatoms suggests that the former often experiencephotoinhibition at comparatively low irradiances, and this tolerance of a large absolute range of photon fluxdensities may, in part, explain why di atoms are often associated with spring blooms.
