Research overview: population structure and subspecies of the snow leopard

Although the snow leopard was traditionally treated as a single undivided species, genetic studies using noninvasive samples have proposed dividing it into several geographic subspecies or management units across its vast but fragmented mountain range. This overview surveys the mitochondrial and nuclear evidence for structure among northern, central, and western populations, the cautions raised about limited sampling, and the implications for transboundary conservation across the many countries the snow leopard inhabits. It discusses how range-wide genetic monitoring informs estimates of connectivity and population size, and why defining units matters for coordinating protection of a cat that crosses numerous international borders.
