Robert Whittaker

Definition

Robert Whittaker was a prominent American ecologist known for his groundbreaking work in the classification of ecosystems and biogeography. He is best recognized for proposing the Whittaker classification system, which categorizes ecosystems based on their climate, vegetation, and geographical distribution. This classification is essential for understanding how microbiomes interact within different biogeochemical cycles.
