However, almost all species detected initially were detected at the end of the monitoring period, and again on a follow-up survey after a further 10 years. The overall impact of cane toads on endemic frogs has been largely one of rarefaction rather than elimination. Rather than having a ...
Cane toads (Rhinella marina) are spreading through tropical Australia with a devastating impact on native species. Predators that try to eattoadsare killed by the invader's powerful poisons; in some local populations of crocodiles, goannas and quolls, more than 95 percent of the animals are kille...
The issue is that Australia has no native toad species, so none of the predators(食肉动物)knew how to avoid the toxic toads. As the cane toads advanced east to west across the continent, "they left a wake of dead animals in their paths, "says Sean Doody, an ecologist at the University...
Although invasive species are viewed as major threats to ecosystems worldwide, few such species have been studied in enough detail to identify the pathways, magnitudes, and timescales of their impact on native fauna. One of the most intensively studied invasive taxa in this respect is the cane ...
another animal species that was introduced in Australia from abroad and had a harmful impact on its native ecosystems.Second,the toads could be captured and destroyed by volunteers.Cane toads can easily be caught in simple traps and can even be captured by hand.Young toads and cane toad eggs ...

The Australian Cane Toad The cane toad, Bufo marinus, or giant toad, was introduced to Australia by the sugar cane industry with government sanction, in order to control two specific pests of sugar cane. The grey backed cane beetle and the frenchie beetle. Native to Central and South America...
(Phys.org) —Climate change is one of a number of stressors that cause species to disperse to new locations. Scientists must be able to predict dispersal rates accurately, as the movement of a new species into an area can have a significant, and sometime
Accurate predictions of the potential distribution of range-shifting species are required for effective management of invasive species, and for assessments of the impact of climate change on native species. Range-shifting species pose a challenge for traditional correlative approaches to range prediction,...
