Which three major desert systems host the Crotalus atrox population concentration in the US?
Answer
Sonoran, Chihuahuan, and Mojave Deserts
The Western Diamondback Rattlesnake is deeply entrenched in the major desert ecosystems of the southwestern United States. The text explicitly states that the species is firmly established within the Sonoran Desert, the Chihuahuan Desert, and the Mojave Desert. These regions provide the necessary low elevation, arid to semi-arid conditions, characterized by sand and scrub, which align perfectly with the snake's fundamental habitat requirements and ecological preferences throughout its distribution within the US boundaries.
