Non-native plants in homeowner's yards endanger wildlife, and experts recommend planting more than 70 percent native plants so plants, insects, and birds can thrive. Additionally, researchers are tracking the spread of neurodegenerative diseases in brains. Other segments include fracking wastewater accumulation found in freshwater mussels' shells and a new protein sequencing method used in biological research. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.

Bird lovers across Cyberspace have arrived at the Migration Celebration. When the trillers are a no-show, Professor Bobson knows something is amiss. After he cancels the event, phone calls and social media posts start reporting triller sightings all over Cyberspace. The Professor and kids recruit dozens of citizen scientists to record their observations when they see a triller. When all the citizen scientists have reported back, it leads to a shocking discovery. What is the data telling them? Part of the "Cyberchase" series.
Recapping themes from the prior modules and previewing the junco research of the future, this closing segment reinforces the broad range of important scientific findings involving the Junco. Featuring sound bites from more than a dozen diverse scientists who study juncos, this segment emphasizes the importance of emerging genetic and genomic research tools to complement research in the field. Viewers are reminded to consider all that can be learned from a little backyard bird. Part of Ordinary Extraordinary Junco (Outro).
As a boy growing up in Brazil 40 years ago, Marc Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now, with support from the National Science Foundation, the materials scientist and mechanical and aerospace engineer at UC San Diego, is conducting the first ever detailed engineering analysis of toucan beaks. He says makers of airplanes and automobiles may benefit from his findings. In fact, panels that mimic toucan beaks may offer better protection to motorists involved in crashes.
Researchers hitch a ride with the Mexican Navy to visit the breathtakingly beautiful but critically endangered island habitat of Guadeloupe Island. Led by Drs. Borja Mila and Ellen Ketterson, the team sets out to collect some of the first modern data and genetic samples from the juncos found on the remote island, with the goal of learning the origins and evolutionary history of this mysterious species. What they find could have important implications for the future of this fascinating but imperiled population of juncos. Part of Ordinary Extraordinary Junco (Chapter 5).
In autumn, a strong wind blows flower seeds high in the air and carries them far across the land. One by one, many of the seeds are lost. Some are burned by the sun, while others fall into the ocean. Birds even eat some of the seeds. But some survive the long winter and, come spring, sprout into plants. Soon only the tiniest seed remains, growing into a giant flower and, when autumn returns, sending its own seeds into the wind to start the process over again. Based on the children's book by Eric Carle.
In this episode, citizen scientists are using a wide array of technology applications to collect data on environmental concerns. A group of individuals are using an app to count birds, which generates data on a changing climate. Surfers, using smart tech, track ocean acidification and coastal temperatures. Other projects include collecting data on the migration of monarch butterflies and surveying horseshoe crab populations. In Uganda, World Bank economists and local partners generate data for sustainable development. Part of "The Crowd and the Cloud" series.
Investigates the physical features of a number of "ugly" animals to demonstrate the efficiency of their odd appendages or disproportionate body parts. Studies the nose of the star-nosed mole, the fleshy protuberances in the mouth of the snapping turtle, the warthog's warts and tusks, the vulture's head, the northern elephant seal's proboscis, the proboscis monkey's nose and protruding stomach, the naked mole rat's lack of hair or fur, the whip scorpion's alien appearance, the mouths of deep sea denizens, and the bat's head.
In contrast to the peaceful wildlands featured in the prior segments, the urban campus of the University of California-San Diego (UCSD) seems like an unlikely place to find field biologists studying juncos. But in the early 1980s, some juncos decided to make this atypical urban and coastal habitat their year-round home. Since then, scientists have documented a remarkable array of changes in the physical traits, behaviors, and physiology of the colonist population of juncos at UCSD when compared to juncos from the nearby native range. Part of Ordinary Extraordinary Junco (Chapter 6).
Professor Lawrence Gilbert and his team at the University of Texas at Austin have discovered a population of tropical butterflies that exemplify "evolution in action," and a rare research opportunity. Gilbert says they may be witnessing a species of butterfly splitting into two different species. The stars of this research are the Heliconius butterflies, found in Central and South America. Despite the genetic similarities between the two groups of the butterflies, one group is showing a color preference during mating. With support from the National Science Foundation, Gilbert and his team are working to gain insights about genetics, behavior, ecology, and evolution.
Hummingbirds live only in the Americas, and their diversity numbers 350 species. They are part-time carnivores that must catch animals that compromise ¼ of their diet. Demonstrates how they can hover, fly backward, and move their wings in figure eights at 200 wind-beats per second in slow and stop motion images. Also reveals that every night their bodies go in torpor (mini-hibernation) so they don't starve while they can't consume nectar. Also sees how they co-evolve with flowers through pollinating mutualisms, and acquired their aerial skills by evolving from ancestors of swifts, their nearest relatives.
One of the oldest, most successful arthropods on Earth, horseshoe crabs have existed for over 350 million years. But in recent years their populations, have crashed by 75% from overfishing, resulting in moratoriums on catching them. Few of us know that most human lives depend on the valuable, shockingly blue blood of these "living fossils." Even more surprising, a tiny shore bird, the red knot, is so dependent on them that the crabs' population crash may make these long-distance flyers extinct. This mystery of mutual dependencies emerges from filmmakers and scientists revealing a disturbing ecology story ranging from the Arctic regions to the southern tip of the Americas.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, having made their way beyond the great valley, Moko and Totemie discover a blanket of white stretching out in front of them. An old man tells them that once they get to the other side they will see what so many others have dreamt of seeing, but that they must fly like birds. He offers them a strange kite. As the wind picks up, they hang on tight and fly off from the salt pan.
