Abstract:
We describe surplus-killing of endangered giant kangaroo rats (Dipodomys ingens) by endangered San Joaquin kit foxes (Vulpes macrotis mutica) and consider the conditions that may have promoted such killing. We also use results of extensive mark-recapture surveys of rodents to document a decline in local density of the giant kangaroo rat that was likely caused by surplus-killing.
