We have sought works that promote unusual and unexpected connections among seemingly disparate subjects, and that are distinguished by the unique talents and perspectives of their authors. Previous volumes spanned topics as diverse as treeshrew behavior and grassland ecology, but none have addressed such an extremely complex conservation dilemma as the one explored herein. Cane Toad Wars engagingly recounts the most recent phase in Richard Shine’s illustrious, career-long obsession with a fascinating continent and its biota. Previously, Rick had mainly studied the natural history of lizards and snakes, but here he turns to the ecological, cultural, and political processes underlying a notorious alien’s success story—indeed, his creatures of choice are famously emblematic of human intervention gone haywire. Technically, alien species are those not present in a region prior to modern times; invasive species are aliens whose exploding populations negatively aff ect native eco- systems and/or human welfare. Averaging roughly two pounds each, Cane Toads were introduced from the Neotropics to the Land Down Under in 1935 to control beetle pests in commercial sugarcane. Th ey are veritable eating and breeding machines and—squat bodies notwithstanding—astonishing long- distance hoppers. Within decades, these drab (some would say grotesque) amphibians had failed at their intended purpose but increased dramatically in population size and distribution, their explosive deployment causing cata- strophic declines among some endemic wildlife. In the pantheon of invasive species, Cane Toads were soon superstars. vii
