Exploring the relation between the size spectrum of plankton communities and carbon export in the ocean

In the oceans, a nearly constant biomass of organisms is found in equal log- intervals of body-size. This large-scale regularity is referred to as the size spectrum. In this new modelling study, we find that parameters of the size spectrum correlate strongly with the export and export efficiency of particles into the deep ocean. These...

The seascape of fear and the biological carbon pump

Organisms adapt to predation risk by changing their behavior. A new study from the Centre for Ocean Life demonstrates how defensive behaviors of marine pelagic organisms, from phytoplankton to fish, may significantly change the intensity of the biological carbon pump and, hence the ability of the ocean to sequester carbon.

Optimality of long-distance migrations

In a new paper, researchers from the Centre for Ocean Life explore the way behavioural traits can influence long-distance migration patterns of large organisms such as sea turtles in the ocean.

Trophic interactions drive diel vertical migration patterns

Using a game theoretic and mechanistic model, researchers from the Centre for Ocean Life showed how traits influencing predator-prey interactions shape the diel vertical migrating behavior of copepod communities.

Predator prey games in multiple habitats reveal mixed strategies in diel vertical migration

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 mathematical notions first developed to describe the interactions between several economic players.
