Cane sprouts in shady areas of WA


They have found cane bushes moving throughout the day in some shaded areas of Western Australia even though the toxic pest is usually nocturnal.

It is believed that feared amphibians are active at night in Australia to avoid heat.

But the Kimberley region has sandstone gorges, some of which offer the shade enough to provide more comfortable habitats.

Several miles away, in more exposed places, other stocks of cane toads remain nocturnal.

Researcher at the Macquarie University, Simon Clulow, said it was amazing to see that the species change from this fundamental behavior.

"This suggests that frogs are particularly good at changing their behavior in response to their environment, something known as behavioral plasticity, which could help their invasive expansion into new environments," he said.

The team looked at cane toads near the border of invasion to the Wilderness Questro Park from 2013 to 2015.

Using remote cameras in eight locations, the researchers tracked the toads activity and dissolved some who were active during the day to examine their eating habits.

Principal author, Sean Doody, of the South Florida University of Saint Petersburg, said the team found that toads that were active during the day were more likely to flee from # 39; an observer than the night toads.

"This increase in the fall may have been due to the fact that they are at greater risk for predators at night, or to be more conspicuous for predators during the day," he said.

It is not known whether the toads prefer to be active during the day, or if the change was beneficial.
