“…It is therefore common for models to use different Q 10 factors for phyto-and zooplankton (e.g. Archibald et al, 2022). However, the temperature response of phototrophic plankton is more complex, and recent experimental work has shown a strong dependence on the resource environment (Schaum et al, 2017;Thomas et al, 2017;Marañón et al, 2018).…”

Here we review, synthesize, and analyse the size-based approach to model unicellular plankton cells and communities. We first review how cell size influences processes of the individual the cell: uptake of dissolved nutrients and dissolved organic carbon, phototrophy, phagotrophy, and metabolism.We parameterise processes primarily from first principles, using a synthesis of existing data only when needed, and show how these processes determine minimum and maximum cell size and limiting resource concentrations. The cell level processes scale directly up to the structure and function of the entire unicellular plankton ecosystem, from heterotrophic bacteria to zooplankton. The structure is described by the Sheldon size spectrum and by the emergent trophic strategies. We develop an analytical approximate solution of the biomass size spectrum and show how the trophic strategies of osmotrophy, light-and nutrient-limited phototrophy, mixotrophy, phagotrophy depend on the resource environment. We further develop expressions to quantify the functions of the plankton community: production, respiration and losses, and carbon available to production of higher trophic levels, and show how the plankton community responds to changes in temperature and grazing from higher trophic levels. We finally discuss strengths and limitations of size-based representations and models of plankton communities and which additional trait axes will improve the representation of plankton functional diversity.

“…It is also less than the Q 10 values often used in plankton simulation models (e.g. Archibald et al, 2022). The reason for the relatively slow increase in division rates is that the cells are generally limited by encounter with resources (nutrients, Figure 16: Effect of varying the temperature between 0 and 25 degrees in oligotrophic/eutrophic conditions (left/right columns; Fig.…”

Here we review, synthesize, and analyse the size-based approach to model unicellular plankton cells and communities. We connect cell-level processes to cell size and to first principles of diffusion, geometry, and fluid mechanics. We scale cell-level processes up to the plankton community size distribution to show that first principles determine overall plankton community structure and function. We first review how cell size influences processes of the individual the cell: uptake of dissolved nutrients, phototrophy, phagotrophy, and metabolism. We parameterise processes by combining first principles with a synthesis of existing data. We show how uptake processes determine limiting resource concentrations and trophic strategies. The strategies at the cell levels scale directly up to the structure and function of the entire unicellular plankton ecosystem. The structure is described by the Sheldon size spectrum and by the emergent trophic strategies. We develop an analytical approximate solution of the biomass size spectrum and show how the trophic strategies depend on the resource environment. The functions of the plankton system are primary production, respiration and losses, and carbon available to production of higher trophic levels. We show how these functions vary with the environment in a chemostat setting, in a water column and in the global plankton ecosystem. We finally discuss strengths and limitations of size-based representations and models of plankton communities.HighlightsReview of how cell size affects resource uptake, losses, and metabolism.Closed-form solutions of limiting resources and size spectrumScaling from cell-level processes to global-scale size structure and ecosystem functions.
