Even small changes can have profound effects on ecosystems from "summary" of The Serengeti Rules by Sean B. Carroll
In the Serengeti, one of the most iconic ecosystems on Earth, a simple experiment was carried out that revealed an astonishing truth - even small changes can have profound effects on ecosystems. By removing a single species - the top predator, lions - from the equation, the entire ecosystem underwent a dramatic transformation. The absence of lions led to a boom in the population of herbivores, which in turn decimated the vegetation, ultimately leading to a collapse in biodiversity. This phenomenon, known as a trophic cascade, illustrates the delicate balance that exists within ecosystems. Each species plays a crucial role in maintaining the equilibrium, and even the slightest disruption can have far-reaching consequences.
