Abstract

INTERPRETING THE DIVERSITY AND BIOGEOGRAPHY OF PHYTOPLANKTON WITH AN OCEAN MODEL

Numerical models provide a platform with which to synthesize understanding of fundamental physiological and biophysical constraints at the individual scale, and examine how these constraints play out at the ecosystem scale. Simulations provide both diagnostic and prognostic opportunities, particularly when working hand-in-hand with field and laboratory studies. They also provide accessible visualizations of ocean processes for communication with the public. We will describe numerical simulations of diverse phytoplankton communities in the global ocean using a trait-based model. The simulations predict patterns of phytoplankton biogeography and diversity which provide hypotheses for, and are tested by, data from the TARA Oceans global survey. They allow us to infer the relative roles of factors (e.g. predation, dispersal) that shape patterns of diversity and community assemblage. We will describe a museum exhibit to illustrate the diversity and biogeography of marine plankton based on visualizations of the simulations.
