Interaction matters: Bottom‐up driver interdependencies alter the projected response of phytoplankton communities to climate change

Abstract: Phytoplankton growth is controlled by multiple environmental drivers, which are all modified by climate change. While numerous experimental studies identify interactive effects between drivers, large‐scale ocean biogeochemistry models mostly account for growth responses to each driver separately and leave the results of these experimental multiple‐driver studies largely unused. Here, we amend phytoplankton growth functions in a biogeochemical model by dual‐driver interactions (CO2 and temperature, CO2 and ligh… Show more

“…Our results highlight a variability over 5-10 years (Figure 8a) and suggest a potential change in seasonality and annual CO 2 sink if primary production changes in the future (e.g. Bopp et al, 2013;Leung et al, 2015;Fu et al, 2016;Kwiatkowski et al, 2020;Krumhardt et al, 2022;Seifert et al, 2023).…”

“…The implications of physiological rate changes in exponentially proliferating organisms are often not easy to grasp but are ultimately the drivers of bloom dynamics and biogeochemical cycling ( 51 – 53 ). For better illustration, we calculated theoretical biomass accumulation based on growth rates for each of our treatments without dilution (i.e., as in a bloom modeled without loss terms; fig.…”

“…Several studies (Donahue et al, 2019;Seifert et al, 2020, Seifert et al, 2023 presented that phytoplankton community composition can be significantly affected by changes in environmental conditions. Looking at the Equation 1 when the coefficient of the explanatory is negative (Table 2), the evolution of the parameter of this coefficient is opposite to the phytoplankton density, i.e., when the observed parameter increases, the phytoplankton growth drops and vice- versa.…”
