摘要：

To account fully for the pattern of translocation of soil by pocket gopher activity in Mima moundfields, I investigated soil mining in relation to location along the mound-intermound topographic gradient. From September 1986 to November 1987, at Miramar Mounds National Landmark in coast San Diego County, California, the total soil mined by pocket gophers (Thomomys bottae) was estimated by measuring the mass of soil deposited in surface heaps and counting the numbers of plugged surface-access tunnels on mound and intermound zones associated with 10 Mima-type mounds. Surface heap deposition was greatest in late fall and early winter, whereas the digging of surface-access tunnels was most frequent in spring and early summer. Total soil mining equalled 28.54Mg.Ha-1.yr-1. -from Author
