AbstractSmall mammals in desert environments are important links in ecosystem energy flow, with their densities often effecting the abundance of their primarily predators. Granivorous small mammals also affect seed dispersal and can shape vegetation characteristics. Consequently, factors affecting small mammal abundance are important in understanding community and ecosystem structure and dynamics. Small mammal abundance has been attributed to levels of precipitation/primary productivity (bottom up) and/or removal by predation (top down). However, small mammal abundance can vary greatly over the landscape in relatively short (
