can toads are considered a pest in australia are there anyways that they can adapt to their surroundings without the food chain being damaged
I do not know anything promising about the cane toad population explosion in Australia. The toads do not even do what they were imported to do, eat cane beetles.
The following excerpt on eradication attempts is from wikipedia:
" Currently, most attempts to curtail the invasion of cane toads have been unsuccessful. Many of these strategies involve the physical trapping of toads. Since the largest selective pressure on cane toads currently is intraspecies competition, these physical removals often only improve the conditions for untrapped toads. Also, since migration is high, any area purged of toads would most likely be reinvaded quickly. Also, trapping methods will also capture unintended native species.[24]
Many new ideas have been proposed to control the cane toad population. Some have suggested introducing a native viral or bacterial pest of the toads, but this has potential to once again invade native species. Two similar strategies have been proposed, both of which focus on fecundicity. One involves the release of sterile males into the population. These males would compete for resources with other males, while themselves not being able to reproduce. A second strategy would be to insert a gene in female toads which would allow them to only create male offspring. In theory, this would limit the reproductive rates and control the population. It is difficult to determine the efficacy and dangers of these approaches, as these methods have never been attempted, especially on a large scale. ... "
