ARCTOS Guest seminar with Thomas Kiørboe: Predation in a microbial world
We are happy to announce a second ARCTOS Seminar in March, with a focus on microbial ecology!
The seminar will be held on Wednesday, March 11th at UiT Lille auditorium E-102 (Norges Fiskerihøgskole, NFH) and via the Teams link below. We will hear from guest researcher Thomas Kiørboe from the Technical University of Denmark.
There is an opportunity for a student presentation (20 min) at the seminar, please reach out to arctos@bfe.uit.no if you are a PhD candidate or Master’s student interested in giving a talk.
Program:
14:00 Welcome
14:10 Thomas Kiørboe (professor, Technical University of Denmark) ‘Predation in a microbial world’
Abstract:
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.
The presentation will be rich in videos and animations.
