In recent decades, as the population size of amphibians has significantly declined, the survival status of amphibians has been studied by a growing number of ecologists and conservationists. Zoige wetland is not only the largest plateau peat bog in the world but also one of the biodiversity conservation hotspots in China. Three species of amphibians inhabit this region, Rana kukunoris, Nanorana pleskei, and Bufo gargarizans minshanica. Previous studies showed that the populations of the three species have decreased at different rates. In the present study, we monitored the population ecology of the Asiatic toad (B. gargarizans minshanica) in Zoige wetland using artificial cover from 2011 to 2014. The results showed that:the population fluctuated significantly at the sampling sites; the analysis of age structure showed that the population has been increasing; the number of individuals had an apparent positive linear relationship with the distance from the brook (P<0.01); the number of individuals increased with the distance from the brook; and the line shape was more effective than the square shape in monitoring this species (P=0.018). We also found that the fatness of sub-adults of Asiatic toad did not exhibit significant difference among the seasons. We hypothesize that the Asiatic toad has high migratory capacity, as it may migrate along fixed routes circularly. For those species that have a broad home range and move long distances, such as the Asiatic toad, we should protect the optimal habitats of the species and prevent their fragmentation.
