Pumas have one of the largest ranges of any wild mammal in the Americas, extending from Yukon in Canada to Patagonia in Southern Chile and Argentina. While this range suggests a high level of habitat adaptability, their actual abundance within their geographical distribution might be comparatively more constrained by certain physical and biological factors including availability of prey, human activities such as persecution and habitat change, presence of large carnivores that could be territorial competitors with larger or overlapping territory including cougars and jaguars and other limiting resource factors.
