Abstract:\u00a0<\/i><\/p>\n
The role of predation in the microbial world is like that in the macroscopic world: it makes energy flow between organisms to form food webs, regulates the dynamics of prey populations, and it is a source of biodiversity. However, mechanistically, predation plays out very differently in the two worlds since in the microbial world viscosity impedes predator-prey contact, there is no vision to facilitate prey (and predator) perception, and observed behaviors are often counterintuitive. I will demonstrate how various groups plankton, from few micron-sized nanoflagellates to mm-sized copepods, have overcome the impeding effect of viscosity by a fascinating diversity of adaptations, and how microbial predators have balanced the fundamental problem of eating without themselves being eaten. The latter trade-off is a key ingredient in the trait-based models of pelagic ecosystems that have been developed at DTU during the past years.<\/p>\n
The presentation will be rich in videos and animations.<\/p>\n<\/div>\n
