The video tutorial covers biodiversity, explaining its three levels: genetic, species, and ecosystem diversity. It discusses the importance of biodiversity in maintaining healthy environments and the ability to respond to changes. The video also explores environmental stressors, population bottlenecks, and the differences between specialist and generalist species. Finally, it explains how biodiversity is measured through richness and evenness.
