Scientists Look to Soil for Answers on Climate Change

3m 7s

Plant life on our planet is reacting to the changing climate. So scientists like Jane Zelikova are turning to the soil for an insight as to what is going on. Here in Kansas we see her and her research colleague Dr. Megan Machmuller digging down to take soil and root samples. She explains how grass systems play a vital role in carbon sequestration and the importance of necromass.

Senegal Chimpanzees Seek Shade In a Cave

2m 47s

In Senegal a troop of critically endangered West African chimpanzees seek shade in a cave to avoid the savanna temperatures which at the peak of the dry season push the chimps to their limits. This is a behavior never recorded before, and as with many precious resources, when the whole troop arrives, tempers can flare. As the climate continues to warm their limits will be pushed even further.

The Zebra Finches' Battle to Survive

3m

In the Australian Outback, we follow Mylene Mariette as she sets up an unusual experiment that reveals something extraordinary about the zebra finches battle to survive. When it gets really hot out here, these small birds can sing to their unhatched eggs, alerting them to the baking conditions. This in turn causes the new born chick to be smaller, increasing their chance for survival.

The Wild Camels of Mongolia's Gobi Desert

On the Turks and Caicos Islands, animals have a far greater ability to adapt to a changing world than we thought. Anthony Herrel studies how Silver Key anoles have evolved to keep up with destructive weather in the tropics. With changes in legs, feet, and aerodynamics, evolution is taking place at incredible speeds.

Catching Darwin's Finches on the Galápagos Islands

2m 24s

Early morning on the Galápagos Islands and Jaime Chaves is catching Darwin’s finches, endemic to these islands, in order to continue decades of work studying the size of these birds' beaks. The beaks are changing shape and size, not over millions of years but from one generation to the next, and now scientists like Jaime are studying the role humans are playing on the lives of these birds.

A Sea Lion Chase

2m 32s

In a remote cove on the Galápagos islands sea lions have recently started to hunt yellowfin tuna in response to dwindling fish stocks. The tuna are faster than the sea lion so they rely on teamwork.
