The consequences of demographic reduction and genetic depletion in the endangered Florida panther

This study characterized the health and genetic status of the Florida panther, a tiny, isolated puma population reduced to a few dozen animals. The authors documented inbreeding-associated problems including poor sperm quality, cryptorchidism, cardiac defects and apparent immune compromise, alongside heavy parasite and pathogen burdens. They argued that demographic collapse and genetic depletion together undermined the population’s viability and disease resistance. The findings provided the scientific basis for the landmark genetic restoration that introduced Texas pumas to revive diversity. As an epidemiological reference, the paper links inbreeding to infectious and parasitic disease susceptibility in a wild felid, illustrating how small population size compounds disease risk and shaping conservation strategy for one of North America’s most endangered cats.
