Title: Conflicting missions: How zooplankton feed, survive, and reproduce
Abstract: The fundamental Darwinian missions of any organism - to feed, survive, and reproduce - may conflict with one another: feeding may compromise survival, and reproduction may interfere with feeding. Natural selection has tailored the morphology and ecology of organisms to balance these tradeoffs. By means of video clips and animations I will show examples of how marine zooplankton - that live in a viscous and nutritionally dilute environment - execute the missions and optimize their behavior to balance the tradeoffs. A mechanistic understanding of the behavioral traits and a quantification of the tradeoffs allow predictions of optimal behavior in various environments. Using a trait-based approach I will finally demonstrate how such insights may be used to predict trait biogeography and properties of pelagic ecosystems.
