Global warming threatens Australia's iconic kangaroos
Date:10/15/2008

As concerns about the effects of global warming continue to mount, a new study published in the December issue of Physiological and Biochemical Zoology finds that an increase in average temperature of only two degrees Celsius could have a devastating effect on populations of Australia's iconic kangaroos.

"Our study provides evidence that climate change has the capacity to cause large-scale range contractions, and the possible extinction of one macropodid (kangaroo) species in northern Australia," write study authors Euan G. Ritchie and Elizabeth E. Bolitho of James Cook University in Australia.

Ritchie and Bolitho used computer modeling and three years of field observations to predict how temperature changes that are considered to be likely over the next half-century might affect four species of kangaroos. They found that a temperature increase as small as a half-degree Celsius may shrink kangaroos' geographic ranges. An increase of two degrees may shrink kangaroos' ranges by 48 percent. A six-degree increase might shrink ranges by 96 percent.

Ritchie says that generally accepted climate models predict temperatures in northern Australia to be between 0.4 and two degrees warmer by 2030, and between two and six degrees warmer by 2070.

The most significant effects of climate change are not necessarily on the animals themselves, but on their habitatsspecifically, in amounts of available water. This is particularly true in Northern Australia, says Ritchie.

"If dry seasons are to become hotter and rainfall events more unpredictable, habitats may become depleted of available pasture for grazing and waterholes may dry up," the authors write. "This may result in starvation and failed reproduction or possible death due to dehydration for those species that are less mobile."

And although kangaroo species may be mobile enough to relocate as the climate changes, the vegetation and topography for which they are ad
