Research overview: regional genetic structure in jaguars

Although jaguars are best treated as a single species, they do show some geographic genetic structure relevant to conservation. This overview surveys studies documenting differentiation across the jaguar's range, often associated with barriers such as the Amazon River and the divide between Central and South American populations. It discusses how this structure defines management units and informs strategies to maintain connectivity, since northern populations in Mexico and Central America are more isolated and threatened. The piece explains the distinction between recognizing formal subspecies and identifying conservation-relevant populations, a recurring theme in felid taxonomy. It connects regional structure to landscape genetics, showing how rivers, habitat, and human barriers shape gene flow in a wide-ranging big cat, and why preserving corridors matters even within a largely panmictic species.
