Aussie meat ants may be invasive cane toad's Achilles' heel

Ecologists in Australia have discovered that cane toads are far more susceptible to being killed and eaten by meat ants than native frogs. Their research published in the British Ecological Society's journal Functional Ecology reveals a chink in the cane toad's armour that could help control t...

Racing cane toads reveals they get cold feet on Southern Australia invasion

Cane toads weren't allowed to compete in the Olympics, but scientists have raced cane toads in the laboratory and calculated that they would not be able to invade Melbourne, Adelaide or Hobart and are unlikely to do well in Perth or Sydney, even with climate change. According to research by Dr ...

Invasion of the cane toads

Why do some invasive species expand rapidly in a new environment while others do not" Scientists from the United States and Australia are beginning to make headway on this question after analyzing how fast cane toads invaded different regions of Australia. Using over 70 years of data o...

Replacing corn with perennial grasses improves carbon footprint of biofuels

...that would take decades to repay. While perennial grasses add carbon to the soil each year, DeLucia said, it could take up to a century for the sugar cane to rebuild soil carbon to former levels on native land.
