Description
"Throughout the world, closely related species are found on landmasses separated by wide stretches of ocean. What explains these far-flung distributions? Why are such species found where they are across the Earth? Since the discovery of plate tectonics, scientists have conjectured that plants and animals were scattered over the globe by riding pieces of ancient supercontinents as they broke up. In the past decade, however, that theory has foundered,...

Description
Tells a story that encompasses two great, insightful theories that together explain the strange patterns of life across the world, evolution and plate tectonics. Includes many fascinating tales, of pygmy mammoths and elephant birds and of radical ideas by bold young scientists first dismissed and later, with growing evidence, widely accepted. From publisher description.

Description
The prairies of the American west, the pampas of Argentina, the steppes of Russia, and the veldt of South Africa all share at least one thing in common: they are covered with miles upon miles of grass. This program can help students learn to identify the climates, life-forms, and behavioral adaptations that correspond to each type of grassland biome. Factors that threaten the survival of these habitats' distinctive animal communities-and of the ecosystems...
10) Desert biomes
Description
Whether it's a stretch of sand dunes in equatorial Africa or a cactus-covered plain in California, any place that receives less than ten inches of rain per year is considered a desert. By comparing and contrasting arid and semi-arid regions, this program provides students with a balanced picture of the Earth's desert biomes. The program also investigates how the few plants and animals that inhabit these ecosystems survive the extreme temperatures...
11) Tundra biomes
Description
About a fifth of the Earth's land surface is tundra: cold, dry, treeless, and home to a diverse range of inhabitants including lichens and lemmings, sedges and snowy owls, and dwarf willow bushes and musk oxen. By viewing this program, students can develop a fundamental appreciation for the world's Arctic and Alpine tundra biomes. The plants and animals that populate tundra environments are clearly identified, along with the adaptations that enable...
12) Outback
Description
The Australian continent is covered by desert, including parts of the country's interior where saline lakes and bizarre rock formations can also be found. Yet these deserts are full of life. Aboriginal communities have adapted to the harsh conditions and have not been displaced here as they have in other areas. The wildlife in this area has also had to adapt. From kangaroos and dingoes, to the prolific birdlife and feral animals that thrive in this...
Description
Scientist, cartographer, and ecological pioneer, Alexander von Humboldt set himself a vast goal: "to find out how the forces of nature interact upon one another." This program follows the first two years of Humboldt and Bonpland's explorations as they charted rivers, gathered samples, and documented thousands of species of fauna and flora in Colombia, Cuba, and the Andes. Along with striking location footage, many of the expedition's original maps,...
Description
At one time, lush, steaming jungles covered much of the planet's land mass. Through this program, students can expand their understanding of rainforests and how their inhabitants live. Special attention is given to the threats to these incredibly rich ecosystems, home to more than half of the different kinds of animals and plants that live on Earth.

Description
This Science Screen Report studies how deserts form and how organisms adapt to these harsh environments. Defining a desert as a vast area of windy, arid land, the program identifies the Gobi and Sahara as common examples as well as regions of the Arctic and Antarctic. It demonstrates that many of these supposed wastelands contain surprisingly high levels of biodiversity, and shows how overgrazing and population increase can desertify forest habitats...
19) Fiji
Description
Situated in the South Pacific north of New Zealand, the Republic of Fiji was settled as far back as 3500 BC. With the help of foreign settlers, Ratu Seru Epenisa Cakobau united part of Fiji's warring tribes under his leadership and established a united Fijian kingdom in 1871. The British subjugated the island in 1874 and brought over Indian contract laborers. This film examines how, after gaining independence from British rule in 1971, Fiji has struggled...
20) Agriculture
Description
Before agriculture, early humans were hunter-gatherers, moving from place to place to follow herds of animals. The development of agriculture gave rise to the beginning of civilization and cities. Learn about the origins of agriculture, the science of soil, the needs of plants, farming techniques, and the future of farming.
