Bio-Modelling Seminar Series (BMSS)

Tid: 2017-10-23 15:15 till 16:00 Seminarium

You are most welcome to the next Bio-Modelling Seminar by Ken Haste Andersen, Professor in theoretical marine ecology at AQUA, DTU, and Deputy chair in the Centre for Ocean Life.

Characteristic sizes of life in the ocean  The size of an individual organism is a key trait to characterize its physiology and feeding ecology, often through power-law relationships. However, such size-based scaling laws may have a limited size range of validity or undergo a transition from one scaling exponent to another at some characteristic size. I review size-based scaling laws for resource acquisition, mobility, sensory range, and progeny size for all pelagic life in the ocean, from bacteria to whales. Further, I develop simple theoretical arguments for observed scaling laws and the characteristic sizes of a change or breakdown of power laws. The characteristic sizes are used to divide life in the ocean into seven major realms based on trophic strategy, physiology, and life history strategy. Such a categorization represents a move away from a taxonomically oriented description toward a trait-based description of life in the oceans. Finally, I will discuss life forms that transgress the simple size-based rules and identify unanswered questions.


 Please contact me if you would like to have a meeting with Ken before the seminar. 


Kind regards,
