Cycles, Phase Analysis, and Synchronization in Ecological Populations - A Tale of Population Dynamics

Explore a conference talk on population dynamics in ecology, focusing on cycles, phase analysis, and synchronization. Delve into the hare-lynx cycle, time series analysis of lynx abundance in Canada, and tri-trophic population models. Examine phase evolution extraction from time series data and coupled predator-prey models. Investigate self-sustained oscillations in single populations and chemostat models. Learn about synchronization experiments and size-structured population modeling, with a focus on Antarctic krill population cycles. Analyze long-term cyclic persistence in laboratory predator-prey systems using wavelet analysis techniques. Discover methods for extracting phase relationships and identifying cyclic succession patterns in ecological populations.
