Temperature-Correlated Changes in Phytoplankton Community Structure Are Restricted to Polar Waters
WOS:000359666100045 Globally distributed observations of size-fractionated chlorophyll a and temperature were used to incorporate temperature dependence into an existing semi-empirical model of phytoplankton community size structure.
