Inadvertent consequences of community‐based efforts to control invasive species

摘要: Attempts to manipulate species abundances can have unforeseen consequences. Our studies suggest that community-group efforts cull cane toads (Rhinella marina) invading Australia may interfere with the toad's local enemies. Abundance of toad parasite Rhabdias pseudosphaerocephala and ant Iridomyrmex reburrus (a predator) decrease when community groups spray antiseptic (Dettol) at pond edges kill toads. trials show Dettol kills parasitic larvae repels predatory ants; thus, control reduce natural regulation. Conversely, volunteer “toad-busters” traversing isolated localities collect spread via muddy footwear. remain alive in boot-treads for least a week, our field data reveal changed dynamics areas where are most active. Thus, impacts culling activities on this invasive be exacerbated or undermined by inadvertent interference host–parasite predator–prey interactions.
