Research overview: the reduction of puma subspecies from thirty-plus to six

The puma once carried more than thirty named subspecies across its vast range, but molecular work drastically reduced this count. This overview explains how genetic analysis revealed that North American pumas, despite occupying a huge area, are genetically nearly uniform owing to a recent recolonization, justifying a single North American subspecies. It discusses how the revised scheme recognized roughly six subspecies, concentrated in South America where the ancestral diversity lies. The piece highlights the conservation impact, particularly for the Florida panther, whose subspecies status and severe inbreeding prompted a genetic rescue using pumas from Texas. It exemplifies the broader pattern of molecular data collapsing inflated, morphology-based felid subspecies lists and reshaping how a wide-ranging cat's geographic variation is understood and managed.
