Explore the quantitative foundations of ecological and evolutionary dynamics in this comprehensive lecture from the ICTP-SAIFR Training Program in Quantitative Ecology. Delve into topics such as evolutionary cycles, genotypic phenotype mapping, fitness landscapes, and evolutionary time. Examine concepts like absorption rate, evolutionary branching, and phage-bacterial interaction networks. Investigate different types of networks, including nestedness and modularity, and learn about measurements, studies, and data related to interaction networks. Discover adaptive dynamics, Darwinian demons, heavy seeds, virus latent periods, and invisibility plots. Gain insights from speakers Joshua Weitz, Stephen Beckett, and Jacopo Marchi from Georgia Tech as they present advanced concepts in quantitative ecology and evolution over the course of 1 hour and 24 minutes.
