This week on the show, Dr. Quave speaks with conservation biologist Dr. Daniel Villar about the deep connections between culture, ecology, and traditional knowledge in the Central Andes. Their conversation centers on Lake Titicaca, one of the world’s highest navigable lakes, where Dr. Villar has studied how traditional ecological knowledge (TEK) shapes and responds to environmental change.  They discuss the many uses of the totora sedge—a plant once used to build floating islands, craft artisanal goods, and provide food for people and livestock—and how its management reflects centuries of indigenous governance and adaptation. Dr. Villar also shares his insights on the role of ethnobiology in conservation, the value of cultural diversity in protecting biodiversity, and how his research sheds light on climate resilience. Don’t miss this fascinating look at the science of survival through the lens of cultural and ecological evolution. #Ethnobiology #LakeTiticaca #TEK #BioculturalDiversity  #FoodiePharmacology #Conservation #Andes #IndigenousKnowledge
