Frogs: The Thin Green Line(en)

An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

Electric Amazon(en)

The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth. Hiding in the vast rivers and streams is an electric grid, a bizarre community of fish with a highly sophisticated electric sixth sense. Using electricity, these "Super" fish can communicate wirelessly, control each other remotely and emit shocks that can stop a human heart. This cryptic world has mystified scientists throughout the ages. Now an intrepid scientist, Will Crampton ventures back into the dark jungles where the inspiration for our technology driven world first emerged, in an attempt to unravel their secrets and unlock the electric code.

The Search for Snow(fr)

In the northern hemisphere, snow is produced by atmospheric low pressure areas that move in from the western Atlantic in the form of huge cloud masses. Snow is vital to the balance of mountain ecosystems. Many animal and plant species at high altitudes depend on it for their survival. But due to global warming, snow is falling less and less. Will there be no more snow in the future? In the Alps and eastern US the situation is clear: as temperatures rise, snow falls less and less, and snow periods tend to shorten. This threatens the mountain flora and fauna. What future do the marmots or alpine bells have without a heat-insulating layer of snow? What future do the marmots or alpine bells have without a heat-insulating layer of snow? What will happen to the conifers in North America without the annual frost protection? Research teams are looking at the implications for snow-adapted species. The documentation shows animal mountain dwellers, who hope for the long-awaited snow every winter.
