The cane toad is estimated to have a critical thermal maximum of 40–42 °C (104–108 °F) and a minimum of around 10–15 °C (50–59 °F). [43] The ranges can change due to adaptation to the local environment. [44] Cane toads from some populations can adjust their thermal tolerance within a few hours of encountering low temperatures.

The arrival of cane toads has also exerted selection pressures on the feeding behaviour and toxin tolerance of snakes. Red-bellied black snakes from regions where cane toads are well-established, have developed increased resistance to toad toxins. [ 24 ]
A young cane toad. The cane toad in Australia is regarded as an exemplary case of an invasive species.Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the ...
Like in Australia, cane toads were introduced in Florida in the 1930s to attack cane beetles, but the local theory suggests their numbers really took off by accident in the 1950s.
Cane toads are an invasive, non-native species in Florida, originally found in parts of Central and South America and the Rio Grande Valley in southern Texas. They were brought to Florida in the ...
Australian park rangers believe they have stumbled upon a record-breaking giant toad deep in a rainforest. Dubbed "Toadzilla", the cane toad, an invasive species that poses a threat to Australia's ...
Cane Toads: An Unnatural History is a 1988 documentary film about the introduction of cane toads to Australia. Cane toads were introduced to Australia with the aim of controlling a sugar cane pest, the cane beetle , but they over-multiplied and became a serious problem in the Australian ecosystem .
This makes the rakali one of the very few natural defenses in the fight to contain the cane toad’s population boom and spreading westward. Since the early twentieth century (when cane toads were blindly introduced to supposedly control sugar cane beetles on farms), the toads in Australia have multiplied from an initial 100 animals to as many ...
