Using a nutrient-unicellular-multicellular mechanistic size-based model (that includes the ontogenetic development of copepods) coupled to a global ocean circulation model, we investigate how food-web structure and organisms' size regulate carbon export efficiency at a global scale. This work illustrates the complex relation between the planktonic food web and export efficiency, and highlights the central role of zooplankton and their size structure in regulating particulate carbon export.

Pinti J., Andersen K. H., Visser A. W. (2021) Co-adaptive behavior of interacting populations in a habitat selection game significantly impacts ecosystem functions. Journal of Theoretical Biology.
In this paper, we consider population dynamics and behaviour (diel vertical migration) of two interactive populations. This work is an extension of Pinti & Visser 2019 (AmNat, see below) in which populations were assumed to have fixed biomass. Considering the population dynamics of interactive populations solves counter-intuitive results that emerge when there is e.g. a high predation pressure on prey. Furthermore, we explore the consequences of these games for ecosystem functions (trophic transfer efficiency and carbon export), and show that ignoring the role of behaviour in multi-trophic population models can lead to inaccurate predictions of ecosystem functions.

On land, the optimal path from a point A to a point B is always a straight line, but this is not true in the oceans where one has to consider currents. In addition, we show that different behavioural traits (such as the importance of arriving early, the necessity to save energy or the boldness level of the individual) lead to different optimal migration tracks. Then, we develop a method that can deduct the behavioural traits of the organisms from their observed tracks. The method works reasonably well for artificially-generated tracks, but is yet to be tested for observed migration tracks.

Using a game-theoretic model, we show how traits influencing predator-prey interactions shape the diel vertical migrating behavior of copepod communities. We reproduce diel vertical migration patterns for a a range of copepods in different environments in the California Current, and we show how reverse vertical migration patterns can emerge. To our knowledge, it is the first time that a mechanistic model captures reverse vertical migrations.

Can we apply economic principles to fish ecology and diel vertical migration? It appears that the way fish and zooplankton behave in the presence of other individuals can be derived from game theory, a mathematical notions first developed to describe the interactions between several economic players.
