Changing phytoplankton niches
Friday, 05 May 2015
Our study of phytoplankton niches at Station Cariaco show that phytoplankton can evolve and change their niches over a 10-15 year period. The figure below shows the distribution of mean phytoplankton niche for temperature, irradiance, and nitrate concentration in a cooler period (blue) and a warmer period (red). Temperature and irradiance niches shift to track changes in the environment. The niches of some phytoplankton shift to lower nitrate concentrations as nitrate …
