The Red Centre of Australia is one of the most inhospitable environments on Earth, and yet it teems with an extraordinary array of wildlife. Most of which is found nowhere else. Some of the secrets of this location include the diversity of Australia's various environments. Part of the "Nature's Microworlds" series.

The gray whale has survived the threat of extinction throughout the nineteenth and twentieth centuries. Today, these wonderful giants find refuge in the lagoons of Ojo de Liebre and San Ignacio. These sanctuaries also promote responsible tourism and sustainable fishing methods. Part of the "Bios: Nature and Society" series.
The Great Barrier Reef is the largest reef on the planet and exists in nutrient poor waters. How does the reef support all the diverse organisms that live on the reef? This episode discusses the relationship between coral and algae, which is the key to the survival of the entire ecosystem. Part of the "Nature's Microworlds" series.
Canada's coastal forest is part of an ancient forest system of redwood, spruce, and cedar trees. It is also home to some of the largest aggregations of top predators in North America. The trees of this forest are huge, and forest productivity here rivals even some of the world's biggest tropical rain forests. Part of the "Nature's Microworlds" series.
Host Steve Backshall examines what is by far the largest ecosystem on the planet: the deep sea. It contains some of the most extraordinary and bizarre life forms. There is even life on the deep seabed, where armies of sea urchins, giant wood louse, and deep sea crabs feed from a thick layer of sediment. Part of the "Nature's Microworlds" series.
Conservation efforts benefit everyone, and this episode explores the various efforts to protect the monarch butterfly. Today, the governments of Canada, Mexico, and the United States maintain a common political project in favor of the conservation of these insects. Part of the "Bios: Nature and Society" series.
This episode explores the necessary and yet often times annoying relationship between humans and insects. Some of the insects highlighted include honey bees, driver ants, silk worms, locusts, Anopheles mosquitos, aphids, money spiders, and army ants. Part of the "Nature's Micorworlds: Insect Specials" series.
The habitats of several jungle animals are severely threatened. Organizations are working with local inhabitants to develop conservation models that ensure the jaguar, the scarlet macaw, the Howler monkey, and other species will continue to have a place to call home. Part of the "Bios: Nature and Society" series.
Landscapes and various formations provide an account of the geological history of the planet. The Great Desert of Altar offers enigmatic landscapes that team with biodiversity, and conservation efforts ensure the preservation of the various fauna and flora of the region. Part of the "Bios: Nature and Society" series.
In part three of the exploration of north Florida and south Georgia, a group of students go looking for the gopher tortoise. While at Birdsong Nature Center, they learn the importance of the turtles' burrows. Part of the "Roaming the Red Hills" series.
Insects can be found in baking deserts, lush rainforests, and all points in between. For most, their size seems insignificant; however, the influence insects have on the planet is immense. They make it possible for reptiles, amphibians, and mammals to exist. Part of the "Nature's Microworlds: Insect Specials" series.
At the end of the Yucatán Peninsula is the village Punta Allen. This fishing village is home to the Vigía Chico Fishermen's Cooperative, which practices conservation methods to help combat the effects of tourism. Part of the "Bios: Nature and Society" series.
Arthropod are the most abundant and diverse group of animals in the world. They inhabit every continent and every ocean, and they outnumber all other animal groups combined. This episode investigates what arthropods are, where they come from, and how they have succeeded through genetic mutation, diversity, exploitation, and coevolution. Part of the "Nature's Microworlds: Insect Specials" series.
Deep in Southern Mexico's jungle, the Villa Luz limestone caves support an ecosystem that thrives in a highly poisonous, acidic environment. This rare type of cave is found in few spots on Earth. Geologists and biologists wear gas masks and protective outerwear to explore the caves. All life forms, from microbial colonies to spiders, fish and bats, are interdependent upon the toxic soup of water, sulphur-oxide and hydrogen monoxide for survival.
After Charles Darwin first visited the island archipelago of Galapagos in 1839, it took him another twenty years to decipher that the scene he'd witnessed was the most perfectly preserved biodiversity on the planet. His theory of evolution, published 150 years ago, pulled back the curtain on a debate that had been simmering for years, and still percolates. Today Darwin would be surprised by the tourist mecca Galapagos has become--200,000 visitors a year, 40,000 permanent residents. The impact on the most unique collection of endemic wildlife in the world has been heavy. Too many people are bringing too many of their ways (and invasive species) from the outside world that are threatening the future of this one-of-a-kind place. What would Darwin think of how Galapagos has evolved in the twenty-first century?
Ecological succession is the gradual process by which ecosystems change and develop over time. In this episode, Pinky and Petunia discuss how nothing remains the same and habitats are constantly changing. Part of "The Amoeba Sisters" series.
Psychiatrist and author Dr. Norman Doidge travels across North America to meet some of the pioneering researchers who made revolutionary discoveries about the plasticity of the human brain. He also visits with people, once thought to have had incurable brain injuries, who are now living normal lives. Known in scientific circles as "neuroplasticity," this radical new approach to the brain provides an incredible way to bring the human brain back to life.
Why are trees and other plants green? Seems like a simple question, but the answer is full of surprises. Using a special camera that can pick up light just beyond the visible range, into the near-infrared, viewers get to see trees like never before. These otherworldly images can reveal not only why trees are green on Earth, but what color photosynthetic life on other planets might be. Part of the "It's Okay to Be Smart" series.
The bobtail squid is no bigger than a walnut and is a tasty mouthful for predators in the coastal waters of Hawaii. However, the species continues to thrive in these waters in part because of its symbiotic relationship with a bioluminescent bacteria, which renders the squid virtually invisible to predators. Part of the "I Contain Multitudes" series.
Anyone who has ever driven in freezing rain knows all too well the potential hazards of an ice storm. These powerful winter weather events are also capable of catastrophic impacts on forest ecosystems. Syracuse University bio-geochemist Charley Driscoll and U.S. Department of Agriculture (USDA) Forest Service ecologist Lindsey Rustad are part of a team to monitor how a forest ecosystem responds to and recovers from ice storms. Part of the “Science Nation” series.
