Plants are able to communicate with each other in ways we are only now beginning to understand. Some plants can differentiate between roots of their "family" and roots of other kinds of plants when they touch underground. See how plants "talk" to each other and find out what they talk about!

In this final episode we complete our journey, travelling back from the March equinox to the end of June. Kate Humble is in the Arctic at a place where spring arrives with a bang, whilst Helen Czerski chases a tornado to show how the earth's angle of tilt creates the most extreme weather on earth.
There is no uncommon sight hanging on the trees of Asian black bears, chipmunks, scurrying about in search of food, as well as the sika deer, gracefully descend to the water to supplement your diet with brown algae. The very presence of deer and deer attracts the largest predator in this region - the Amur tiger. But the world's largest wild cat is also at risk. Poaching and destruction of habitat of tigers in the Ussuri taiga in Russia for many years have created a real threat of extinction of this rare animal.
Dr Helen Czerski looks at the anatomy of an avalanche. From shocking eyewitness footage from within an avalanche, to detailed CT scans showing the microscopic changes that cause them, we can now capture exactly what happens as snow transforms into a deadly and unpredictable danger.
The world's cities are growing at a faster rate than any other habitat on the planet. And while most of us imagine them to be concrete jungles devoid of nature, for animals of all shapes and sizes they are just a new habitat filled with new and surprising opportunity. With similar needs to humans, these wild animals face similar challenges, and like us, if they play their cards right, they can find everything they need in the city. With the natural world shrinking, and our urban centres continuing to grow, adapting to life in the city has never been more important. This first episode examines what it takes for these wild residents to thrive in the newest and fastest changing habitat on the planet. From smooth-coated otters at home in Singapore and huge colonies of megabats in Adelaide to reticulated pythons living on the streets of Bangkok, experience our cities through fresh eyes - the eyes of the animals that live in them, and discover a wilder side to a world we think we know.
