Eco, the little bear, travels around the world observing human interactions with the environment. During his journey, he meets many other friends from the animal kingdom and gets a firsthand look into some of the environmental and social problems facing the planet. Eco and his friends provide ways for humans to ensure a healthy planet for the future. Part of "Eco S.O.S." series.

What do crocodiles and leopards have in common? Century-old specimens of both are helping to decode the biodiversity of ecosystems that are under threat today. Researcher Evon Hekkala and curator Joel Cracraft help unravel the mystery of cryptic species. Part of the "Shelf Life" series.
A massive new study has just been released showing that human activities are threatening Earth’s other life-forms in some very bad ways. One million species may be at risk of extinction. Part of the "It's Okay to Be Smart" series.
Sean Carroll, professor at University of Wisconsin-Madison, discusses the delicate balance of ecological systems. He explains how one seemingly minor change in one species can upset an entire ecosystem. Part of the "Ask a Scientist" series.
Around the globe, unique species face extinction from hunting and habitat destruction. George, a Pinta Island tortoise from the Galapagos Islands, is the very last of his kind. Other species were on their way to joining George as the last of their kind--until help arrived.
Five species of sea turtles are found in Florida’s waters and all are listed as threatened or endangered. Biologists off the Gulf Coast of Florida conduct in-water research and monitoring of the turtle species. They are collecting data on population trends and habitat utilization. Part of "The Science Behind" series.
In this episode, host Emily Graslie meets with Bill Stanley, Director of the Gantz Family Collections Center, to discuss the discovery of a new species. The species was stored in the museum's mammal collection for decades until found by professor Kristofer Helgen. Part of "The Brain Scoop" series.
Research in biology would be impossible without a common framework for grouping and distinguishing species. Carl Linnaeus was the first to propose a classification system of organisms. His system developed into the organizational structure used in the life sciences today. Viewers also learn how new scientific names are created and how the existing system has been further refined using DNA studies.
The hydrilla, a non-native invasive plant species, is overtaking Florida's Wakulla Springs, threatening many species that call the waterway home. The hydrilla has such a stranglehold on the springs that its aggressive growth cycle has made it impossible to totally eradicate. Instead efforts are being made to control the plant's growth in an effort to stop its encroachment into Florida's northern panhandle. Segment of video from Wild Chronicles Series.
Peter Pritchard has seen each of the world's 300 species of turtles, but has a real affinity for the giant leatherback sea turtles on a Guyana beach. His conservation efforts with a local community insure that children learn about the turtles' habitats, behaviors, and characteristics. Watch a turtle lay her eggs and see the newly hatched babies race for the sea. Gives additional pertinent facts about this ancient species.
Some conservationists believe that perhaps half of all species on earth will become extinct in the next 50 to 100 years. To prevent that, several groups work to assist efforts at conserving biodiversity. Some of the efforts include taxonomy (cataloging species), managed retreat (letting nature retake areas), saving seeds, and propagating endangered plants. Man's efforts toward destruction and development must be balanced with sustainability.
The lionfish is invading the Atlantic and Caribbean waterways with catastrophic results. This non-native species has no local predators and is propagating at a rate that adversely impacts the coral reef habitats of the Eastern United States, Caribbean, and South America. This is a story of communities banding together to ensure the protection of native species. Scientists and citizens are monitoring the situation, and high school marine biology students are studying the feeding behavior of this voracious predator.
Freshwater mussel species are critical to river ecosystems. But, many species are in trouble. Nearly 70% of freshwater mussel species are considered threatened in some way, according to zoologist Caryn Vaughn at the University of Oklahoma. With support from the National Science Foundation, Vaughn studies the role mussels play in freshwater ecosystems. They work hard filtering impurities from the water. The major problem for freshwater mussels now is habitat fragmentation and channelization by dams.
Invasive animals are often most abundant in habitats impacted by humans. Understanding why this is true may reveal important insights about the ecological impact of many invasive species. The invasive fire ant, Solenopsis invicta, is a notoriously pesky species that benefits when humans disturb natural areas. With support from the National Science Foundation, Dr. Joshua King at the University of Central Florida and Dr. Walter Tschinkel at Florida State University have been exploring the underlying causes and consequences of the association of fire ants with human-altered ecosystems. Part of the National Science Foundation Series “Science Nation.”
New research led by scientists at the University of California, Berkeley, suggests that the shape of some animals' pupils could reveal whether one is hunter or hunted. An analysis of 214 species of land animals shows that a creature's ecological niche is a strong predictor of pupil shape. Species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. In contrast, those with horizontally elongated pupils are extremely likely to be plant-eating prey species with eyes on the sides of their heads.
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
Bullfrogs have arrived in the Arizona Desert, and conservationists are hopping mad. The alien species is wrecking havoc on native frog species. Segment of video from Wild Chronicles Series.
Florida is home to many different wildlife species. The local residents, artists, and scientists provide a glimpse into the state's iconic wildlife. They also share their passion for ensuring the survival and conservation of each species.
In this episode, a cardiologist is called in to consult on a male chimp's annual checkup. Plus, meet a kookaburra and a tawny frogmouth, two unique Australian bird species. Part of "The Wildlife Docs" series.
Hagerman Fossil Beds National Monument in Idaho is home to over two hundred different species of fossil plants and animals: including saber tooth cat, mastodon, bear, camel, ground sloth, and many other species. Over 3,000 new fossil fragments are found each year.
