Explore the ecological and evolutionary consequences of ontogenetic niche and habitat shifts in this 48-minute Santa Fe Institute seminar. Delve into the complex life cycles of animal species that occupy different ecological niches throughout their development. Examine how physiologically structured population models (PSPMs) can be used to analyze the dynamics of populations with ontogenetic habitat shifts. Discover how these shifts can lead to alternative ecological equilibria and create dependencies between predator species in different habitats. Investigate the evolutionary implications of mortality changes in adult habitats, including delayed regime shifts to contrasting ecological states. Learn about individual energetics, energy allocation, foraging specialization trade-offs, and the evolution of metamorphosis. Gain insights into eco-evolutionary dynamics of life cycles and the potential for evolutionary bistability in metamorphosis.
