Which major North American drainage system is listed as part of the historical distribution of the Yellow Bullhead?
Answer
The Great Lakes drainage system
The Yellow Bullhead (*A. natalis*) maintains a broad and historically significant distribution across a substantial portion of North America. This established range covers diverse climatic and ecological zones, underscoring its adaptability. Specifically, its historical distribution encompasses the area associated with the Great Lakes drainage system. Extending from this region, its range continues southward, covering the eastern United States and reaching coastal areas such as the Gulf Coast states. This extensive coverage, from the northern Great Lakes down to the southern Gulf regions, demonstrates the species' capacity to thrive across varying environmental gradients.
