两栖类的

The niche breadths of adults and subadults of three anuran species (Rana kukunoris, Nanorana pleskei and Bufo minshanicus ) in Zoige Wetland Nature Reserve, Sichuan, China were studied. The results showed that the niche breadths of B. minshanicus adults on the 5 dimensional axes including character of pasture, number of yak dung, vegetation coverage, temperature and humidity of ground surface, were narrower than those of R.
