The video discusses natural disturbances and their effects on ecosystems, focusing on two key concepts: resistance and resilience. Resistance refers to an ecosystem's ability to remain unchanged despite disturbances, while resilience is the ability to recover and return to a pre-disturbed state. The video also covers the intermediate disturbance hypothesis, which suggests that moderate disturbances can increase biodiversity. Finally, it contrasts natural disturbances with modern anthropogenic changes, highlighting the increased frequency and intensity of human-induced disturbances.
