Asia covers a vast area that reaches almost halfway round the Earth from east to west. As you'd expect with such a huge land area, it contains a diverse array of habitats. Biogeographically, Asia is part of the Eurasian landmass and some species - such as bears and golden eagles - are found on both continents. Asia began to take its present form about 50-55 million years ago when the Indian tectonic plate collided with the main body of Asia, birthing the Himalayas and the Tibetan Plateau and cutting the warm south off from the cold heart of the continent.
Timelapse illustrates the vigorous race for light, and life, set off by a tree fall.
It took four years to shoot this sequence. The cameraman set immoveable posts in place in the Borneo forest and returned each week to take a still, carefully aligning the frames. The resulting shots were then stitched together digitally to create a timelapse sequence.
Bizarre and ancient life forms in the freezing depths of the world's deepest lake.
The cold here could kill someone in under a minute. The cameraman wore a dry suit and poured boiling water over his regulator before diving to stop it freezing. The seals are extremely shy, so the cameraman had to position remote cameras along a predicted route from their ice lairs. These are the first images of the Baikal seals under the ice.
