Modelling planktic foraminifer growth and distribution using an ecophysiological multi-species approach
We present an eco-physiological model reproducing the growth of eight foraminifer species ( Neogloboquadrina pachyderma , Neogloboquadrina incompta , Neogloboquadrina dutertrei , Globigerina bulloides , Globigerinoides ruber , Globigerinoides sacculifer , Globigerinella siphonifera and Orbulina univ...

We present an eco-physiological model reproducing the growth of eight foraminifer species ( Neogloboquadrina pachyderma , Neogloboquadrina incompta , Neogloboquadrina dutertrei , Globigerina bulloides , Globigerinoides ruber , Globigerinoides sacculifer , Globigerinella siphonifera and Orbulina universa ). By using the main physiological rates of foraminifers (nutrition, respiration, symbiotic photosynthesis), this model estimates their growth as a function of temperature, light availability, and food concentration. Model parameters are directly derived or calibrated from experimental observations and only the influence of food concentration (estimated via Chlorophyll- a concentration) was calibrated against field observations. Growth rates estimated from the model show positive correlation with observed abundance from plankton net data suggesting close coupling between individual growth and population abundance. This observation was used to directly estimate potential abundance from the model-derived growth. Using satellite data, the model simulate the dominant foraminifer species with a 70.5% efficiency when compared to a data set of 576 field observations worldwide.
