13. How might conservation biologists control cane toad populations?

Biologists says that resting toads has been meta physical as apparatus that remove them will often wipe out frogs. Toads in Queensland that lagged lost the invasion arch and hang they were infected mutually a lungworm virus which slows full adults and, in empirical tests, kills completely 30% of baby toads.

14. What are the ramifications (pros and cons) of introducing a natural predator of cane toads?
