Explore the fascinating world of root systems and their impact on biogeochemical cycling in this 54-minute talk by Mingzhen Lu at the Santa Fe Institute. Delve into the evolution of roots over 400 million years, examining how they have adapted to changing climates and reshaped the biosphere. Learn about the intersection of geography, ecology, and economics as Lu discusses the hidden network beneath our feet. Discover the relationship between the "Wood-Wide Web" and urban systems, and how plants domesticated mycorrhizal fungi. Investigate evolutionary trends revealed by paleoecological studies of roots and their implications for the future of technology and civilization. Gain insights into the intense belowground resource competition in plant communities and the maintenance of biome boundaries. Consider the parallels between root systems and economic systems, exploring concepts of recycling innovation and generalist strategies. Reflect on the lessons that root systems offer for addressing global challenges and creating more sustainable futures. Read more
