The quick and the tough: Australia's gnamma animals
Few transformations on earth are as rapid and dramatic as those of gnammas after rain. In no other habitat are you likely to see zero species one week and 50 three weeks later.
In a land of extremes, zoologist Brian Timms is tracking life in one of the most extreme habitats of all.

Plant life in the snow country
While less than 0.15 percent of our continent is carpeted in snow and qualifies as alpine, the Australian Alps bioregion is a biodiversity hotspot.
Plant ecologist Susanna Venn reveals how some of nature's greatest beauties are also its toughest, and just what it takes to thrive in the alpine zone.
