在阿尔泰山追踪雪豹，气候变化下的生存希望
In the remote, precipitous fastnesses of the Altai Mountains, where the borders of Mongolia, Russia, Kazakhstan, and China converge in a tangle of rocky ridges and alpine meadows, the snow leopard (Panthera uncia) remains the most spectral of large predators. Elusive to the point of near-myth, each individual occupies a home range that may span hundreds of square kilometres, stitching together a mosaic of inhospitable scree slopes and icy crags. For conservation biologists, simply confirming a leopard’s presence demands a combination of dogged patience and technological ingenuity, for the cat leaves behind little more than ephemeral paw prints in the snow and the occasional scrape on a boulder.
Modern monitoring techniques have transformed the effort. Camera traps triggered by body heat and motion capture fleeting, ghost-like images at dawn and dusk, while genetic analysis of scat samples can identify individual leopards with enough precision to estimate a population’s size and relatedness. Yet the data come slowly: a single camera array might yield only a handful of usable photographs over an entire season. The work is performed in thin, lung-burning air at over four thousand metres, where the wind scours the skin and the sun’s ultraviolet radiation is a constant hazard. It is a science of incremental revelations, each new record a small triumph against a vast, indifferent landscape.
