AETN Exploration Wed.: Koalas, Ice Age & Salmon
Posted on 15 Jan 2013
Travel from eucalyptus forests to an archaeological dig in the Rockies and the feet of Alaskas most active volcanoes this AETN Exploration Wednesday, Jan. 16, at 7 p.m. Nature investigates the lives of koalas, NOVA opens a portal to the Ice Age, and Life on Fire investigates the origins of salmon that continue a pioneering journey … to the heart of an active volcano!
In Nature: Cracking the Koala Code, you can begin to examine the day-to-day dramas of an extended family of koalas, seen through the eyes of the scientists studying their every move and vocalization. Fascinating social dynamics include territorial displays, vicious fighting and the surprising life and loves of a "traveling salesman" a rogue male who truly plays the field. New science even "cracks the koala communication code," providing insights into their basic language and social structure.
Next, at 8 p.m., in NOVA: Ice Age Death Trap, archaeologists race against developers in the Rockies to uncover a unique site packed with astonishingly preserved bones of mammoths, mastodons and other giant extinct beasts. Their discoveries open a vivid window into the vanished world of the Ice Age.
Finally, at 9 p.m., Life on Fire: The Surprise Salmon travels north to the fresh water that feeds the rivers is snowmelt from North America's highest mountains and most active volcanoes. Time and again, they erupt and poison the rivers. Scientists have only just begun to piece together what might have happened nearly 2,000 years ago, when one race of salmon faced the death of their natal river and were forced back to the open ocean on an exceptional adventure. Navigating between the sulphurous waters, bears, sharks and eagles, the fish escaped the Earth's wrath to give birth to descendants that continue their pioneering journey to the heart of an active volcano.
