Provides an overview of some natural and human-made wonders of the world. Natural forces created mountains and canyons, unique bodies of water, and diverse ecosystems. People made ancient cliff dwellings, Stonehenge, pyramids, the Great Wall, and Hoover Dam, some very significant structures. All reveal the history of earth and its inhabitants.

Sea star wasting syndrome is the largest marine disease event ever seen. Microbiologist Ian Hewson shares what inspires him to study oceanic ecosystems, and how scientists from Cornell University are solving this ecological mystery.
Water fleas are crustaceans, and they are the foundation for the web of life in water ecosystems. They are the most plentiful food source for other water ecosystem organisms. One of nine segments in a series, with all nine available on a DVD.
Predators play a fundamental role in maintaining the health of ecosystems. Research strongly supports the contributions of wolves in particular to the functioning and stability of the overall landscape. Students will learn about conservation methods to reintroduce and protect wolves in the wild. Part of the "Saving a Species" series.
Ants play important roles in many ecosystems, and a team of scientists are surveying ant populations in Gorongosa Park. Leading the study is Leeanne Alonso, she is cataloging the different species of ants in Gorongosa National Park and establishing a species census to monitor the ongoing recovery of the park.
In this footage, two citizen scientists are studying butterflies and conducting biological surveys of varied ecosystems in the Red Hills and Apalachicola National Forest. They document the wide diversity of butterflies in the region. Part of the "Roaming the Red Hills" series.
Zoology is the study of animals and their behavior, and zoologists may study a particular species or group of species. They also study the interactions between animals and various ecosystems. Part of the "I Can Be Anything I Want to Be A to Z" series.
Students learn about the differences between Asian and African elephants and how elephants make a dramatic impact on their ecosystems. After learning about elephants as "landscape architects," students apply the inquiry process to investigate the different tasks of elephants' trunks. Part of the "You at the Zoo" series.
Ana Luz Porzecanski is a conservation biologist who studies wildlife, ecosystems, and the interactions between humans and nature. She also explores ways for various species to coexist and thrive in the same environment. Part of the "Meet the Ologist" series.
Amy Battocletti is a Navy veteran who was awarded an NSF Graduate Research Fellowship in 2014. She’s a doctoral candidate in biology at Georgetown University, conducting research on the impact of genetic variation within plant species in salt marsh ecosystems. Part of the Scientists and Engineers On Sofas 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.
The intertidal oyster reefs along Florida’s Gulf Coast are highly productive ecosystems, but they are threatened by rapid decline. Dr. Kimbro is studying this economically important habitat in order to find a way to restore it. Part of the series "In The Grass, On The Reef."
Contains 8 segments: "Matter and Energy for Life," "Ecosystems," "Populations," "Homeostasis: The Body in Balance," "Inheritance," "Behavior and the Nervous System," "Biodiversity," and "The Biosphere." Students have opportunities to become involved in hands-on activities. Supports the learning of key concepts in biology in tandem with the textbook also offered by the publisher.
This episode features the development of a new camera that detects cancer. Its design is based on the structure of a butterfly's eye. Scientists are also experimenting with ominphobic materials that repel dirt. Studies also reveal that animals are beginning to recolonize ecosystems that were once prime hunting grounds for them. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" 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.
Explores the Olympic Peninsula of Washington State which has a greater variety of habitats than anywhere else in the world. Introduces its abundant plant and animal life and explains the delicate balance between them. Considers the importance of water and rainfall, from the temperate rain forests at the coast, to the lowland forests, mountain forests, and glaciers.
Year after year massive fires continue to rip through the wildland-urban interface (WUI) in Colorado. Some scientists fear that the forests may not be able to recover due to a warming climate. Colorado University PhD student Monica Rother investigates post-fire ecosystems in an effort to predict what the Colorado Front Range might look like in a warmer, drier future. Part of the WildFire PIRE series.
The colorful rock formations at John Day Fossil Beds preserve a world class record of plant and animal evolution, climate change, and ecosystems that span over 40 million years. With over 10,000 square miles of land, visitors can explore the prehistoric past of Oregon and see the impact of geologic forces on earth’s landscape.
Photosynthesis converts light energy from the sun into chemical energy stored in organic compounds, which are used to build the cells of producers and ultimately fuel ecosystems. After providing an overview of photosynthesis, a series of animations describe the inside of the cells of a leaf to explain how the reactions of photosynthesis happen.
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.
