The Auckland Islands are an isolated archipelago of islands far south of New Zealand. They might seem bleak, but they are a surprising sanctuary for wildlife. In summer, hordes of giant sea lions descend upon a desolate beach, and testosterone-driven males begin bloody battles for mating rights. When the pregnant females return to give birth on the beach, chaos ensues. The pups are always in danger of being squashed by overly eager males. Some of the rarest penguins on the planet, the yellow-eyed penguins, are also breeding here and must constantly evade the huge brawling male sea lions. Southern royal albatross, giant petrels and skuas are other species that go to extremes to ensure their offspring’s survival. The drama of summer in the sub-Antarctic islands peaks as the sea lion pups dare to take their very first ocean swims.
Why are vultures bald? Why do some orangutans have big cheeks? And if giraffes have long necks to help them reach the highest leaves, why do they mostly eat low-lying shrubs? Embark on a whirlwind tour around the world as we explore some of nature's most-fascinating evolutionary wonders.
A journey through nature, commerce and adventure, The Fruit Hunters takes us from the dawn of humanity to the cutting of edge of modern agriculture — a series that will change not just the way we look at what we eat, but what it means to be human. The Fruit Hunters' first episode, "The Evolution of Desire," explores the origins of fruit's diversity and tells the story of humanity and fruit's intimate co-evolution. Every variety of fruit has a story, the story of the person who cultivated an individual plant, and then shared something wonderful with the world. To preserve this diversity is to retain this living memory. A passionate few, the fruit hunters, fight to preserve this diversity in a world increasingly dominated by economically driven monoculture.
This film explores why it pays to work as a team as it reveals some of the most captivating and awe-inspiring group parenting stories from the animal world. For most group-living species, living together means dividing the labour. From elephants taking part in hostage negotiations for their babies to banded mongoose all giving birth on the same day, female lions forming a sisterhood to see off interloping males and musk oxen rallying together to defend their calves from hungry wolves... it's truly amazing what some animal parents are prepared to do for the next generation!
As a whole, Africa is a dry continent with deserts dominating the landscape. Wild Africa explores how these deserts were created, and the amazing ways in which animals and plants have evolved to cope with the meagre and unpredictable rainfall, intense solar radiation, shortages of food and lack of shelter. By traveling through the African deserts, Wild Africa reveals that given enough time, a diverse variety of animals and plants can make a living in even the harshest conditions.
Africa's coasts were formed by the break-up of Gondwanaland 100 million years ago. They define the familiar shape of this special continent, and touch on a variety of environments including deserts, mountains, forests, wetlands and savannahs. Wild Africa takes us back in time to witness the birth of Africa and also carries us on a spectacular journey around the edge of the continent.
The Lake Erie water snake, once on the brink of extinction, now looks to be rebounding--thanks mainly to the invasive goby fish that's wreaking havoc on the Great Lakes ecosystem. Can scientists studying this environmental anomaly find a healthy ecological balance?
