Population genetics reveals high connectivity of giant panda populations across human disturbance features in key nature reserve

A surprising lack of genetic isolation was found among giant panda populations within the Sichuan Giant Panda Sanctuaries, despite significant human disturbance. Researchers analyzed 539 fecal samples from Wolong Nature Reserve using tetra-microsatellite markers, identifying 142 unique genotypes and estimating a population size of 164 individuals (95% CI: 153-175). Contrary to expectations, no significant genetic boundaries were detected, even across the national road G350 that bisects the reserve. This suggests higher connectivity than previously assumed, likely due to high migration rates, including confirmed road-crossing events. The study highlights the importance of maintaining habitat corridors for gene flow preservation amid increasing development and tourism threats.
