Teacher toads: Buffering apex predators from toxic invaders in a remote tropical landscape
Even after research identifies new approaches for wildlife management, translating those methods for delivery can be logistically challenging. In tropical Australia, invasive cane toads (Rhinella marina) fatally poison many anuran-eating native predators. Small-scale trials show that vulnerable predators exposed to small (nonlethal) toads can learn to delete toads from their diets, increasing survival of those predators after toads invade. We deployed this method in the remote Kimberley region of tropical Australia, with >200,000 eggs, tadpoles, or metamorph toads released in advance of the expanding toad invasion front. Remote camera surveys before and after “teacher toad” deployment showed that large monitor lizards (Varanus panoptes) were almost extirpated from control plots but remained abundant in treatment plots, indicating broad-scale success of this novel intervention.
期刊介绍：
Conservation Letters is a reputable scientific journal that is devoted to the publication of both empirical and theoretical research that has important implications for the conservation of biological diversity. The journal warmly invites submissions from various disciplines within the biological and social sciences, with a particular interest in interdisciplinary work. The primary aim is to advance both pragmatic conservation objectives and scientific knowledge. Manuscripts are subject to a rapid communication schedule, therefore they should address current and relevant topics. Research articles should effectively communicate the significance of their findings in relation to conservation policy and practice.
