Invasive plant protects Australian lizards from invasive toad: Study
Date:2/23/2012

An invasive plant may have saved an iconic Australian lizard species from death at the hands of toxic cane toads, according to research published in the March issue of The American Naturalist. It's an interesting case of one invasive species preparing local predators for the arrival of another, says Richard Shine, a biologist at the University of Sydney who led the research.

Cane toads were introduced in Australia in the 1930s to control beetles that destroy sugar cane crops, but the toads quickly became an ecological disaster of their own. They produce toxins called bufadienolides, which have proven deadly to many native Australian species that feed on frogs and toads.

Bluetongue lizards are one of the vulnerable species, and their numbers began to shrink significantly after the toads arrived in northern Australia. But there's reason to believe that bluetongue populations elsewhere Australia will fare better as the toads spread across the continent.

"Our study was stimulated by a puzzling observation that arose during research on the ecological impacts of invasive cane toads in Australia," Shine and his colleagues write. "Some lizard populations were vulnerable to bufotoxins whereas others were notand the populations with high tolerance to bufotoxins included some that had never been exposed to toads."

Why would these populations have evolved a tolerance to the toad toxin when no toads were present?

The answer, according to Shine and his colleagues, is likely an invasive plant species known as mother-of-millions, which happens to produce a toxin that's virtually identical to that of the cane toad. After it was imported from Madagascar as a decorative plant some 70 years ago, mother-of-millions has since run amok in parts of Queensland and New South Whales and become part of the diet for local bluetongues.

Shine and his colleagues collected bluetongues from places with and without mother-of-
