Fragmented jaguar populations face increasing inbreeding as habitat connectivity declines, threatening long-term genetic health and adaptive capacity.
Inbred jaguars from isolated populations show reduced fitness, higher disease susceptibility, and lower reproductive success than genetically diverse individuals. The welfare consequences of inbreeding manifest as chronic health problems across the lifespan of affected animals. Maintaining habitat corridors that allow dispersal between populations prevents inbreeding accumulation that would eventually threaten the viability of isolated groups.
