Extreme conservation : life at the edges of the world / Joel Berger.

At the intersection of continents : Beringia's silent bestiary
Motherless children in black and white
Before now
Beyond Arctic wind
Where worlds collide
Muskoxen in ice
When the snow turns to rain
Sentinels of Tibetan plateau
Below the margins of glaciers
The ethereal yak
Birthplace of angry gods
Gobi ghosts, Himalayan shadows
Counting for conservation
To kill a saiga
Victims of fashion
In the valley of Takin
Pavilions where snow dragons hide
Adapt, move, or die
The struggle for existence
A postapocalyptic world: Vrangel
Nyima.
