Phytoplankton biomass is controlled by a combination of “bottom-up” factors such as temperature, light and nutrients and “top-down” factors, in particular zooplankton predation. In a recent study we analysed large-scale data on ocean chlorophyll, copepod abundance and temperature in order to assess the general importance of bottom-up and top-down factors in controlling phytoplankton biomass.
