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.

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.
University of California, Berkeley seismologist Peggy Hellweg discusses the difference between a tremor and an earthquake. She also explains how TremorScope stations record deep tremors along the San Andreas Fault in central California. These stations reveal complex faulting behavior in the deep crust that is surprisingly different from earthquakes in the upper crust.
What is happening with New Zealand forests? A team of University of Colorado fire scientists dig deep into the forests of New Zealand to find clues about past wildfires. They also hope their discoveries will reveal how to protect the fragile ecosystems in the future. Part of WildFIRE PIRE series.
Margaret Leinen, a paleoceanographer and climatologist, shares tales of leading the University of California’s delegation to the Paris Climate Conference. She also discusses her excitement about the imminent arrival of the new research vessel Sally Ride, named for the late astronaut who was the first American woman in space. Part of "The Constellation: Sally Ride Science Conversations" series.
For nearly 40 years, Dr. Ellen Ketterson and her research team from Indiana University have been studying juncos in the mountain forests of Virginia. This segment introduces viewers to the junco, the researchers, and the core methods they use to study birds. Set in field, lab, and aviary locations, one landmark study is highlighted in detail: a long-term field experiment investigating the complex effects of the hormone testosterone on behavior, physiology, and evolutionary fitness. Part of Ordinary Extraordinary Junco (Chapter 2).
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).
What does the dream science internship look like? How about a month of field work in the rugged mountains of Tasmania and New Zealand? This dream came true for three bright students from Salish Kootenai Tribal College in NW Montana. Part of WIldFIRE PIRE series.
Patrick Sanan, who studied mathematics at UC San Diego, explains how he combined geometry and physics to create the virtual tiger in the Oscar award-winning motion picture "Life of Pi."
Scientists Bruce Maxwell and his team explores how invasive lodgepole pine is affecting the landscape of New Zealand and possibly creating a greater risk of wildfire. Part of WildFIRE PIRE series.
Volcanologist Michael Manga and his students study geysers in Chile and Yellowstone National Park. They thread sensors and cameras into the boiling water in an effort to come up with an explanation for why geysers erupt periodically.
On January 4th, 2013 a catastrophic bushfire ripped through Tasmania. In the aftermath, scientists and residents are struggling to figure out if events like this are likely to happen more frequently in the coming years with climate change. Part of WIldFIRE PIRE series.
Cornell geophysicist Katie Keranen traveled to Oklahoma to study the increased occurrences of earthquakes. During her research, she discovered the increase in seismic activity is linked to the disposal of wastewater from fracking.
Join a group of international fire scientists and students as they venture deep into Tasmania's Cradle Mountain National Park to better understand the role of fire in the ecosystem. Part of the WildFIRE PIRE series.
An introduction to sign vocabulary that is specific to science. Many interpreters, teachers, and students are unfamiliar with specialized sign vocabulary because the concepts occur infrequently in daily communication. In this video a Deaf professional signs vocabulary related to his field of expertise. The signs being demonstrated are commonly accepted by the Deaf community, but may not be the only sign for a specific word. Signs often vary across the country, so viewers are encouraged to confirm that signs used in this video are those used in their area/region of the country. Where appropriate, more than one sign or combinations of signs are demonstrated in this video for the same English word.
Juncos, also known as snowbirds, are readily observed in backyards, city parks, and forests. These little gray birds are so common they can be easily overlooked. But for scientists who study animal behavior, ecology, and evolutionary biology, the junco is a rock star. Part of Ordinary Extraordinary Junco (Intro).
Throughout North America, the species known as the dark-eyed junco exhibits striking differences in feather color, body size, and behavior from place to place. These variations among subspecies have caught the attention of biologists interested in diversification, evolution, and speciation. This segment features footage from junco habitats across the continent as researchers try to decode the riddle of the Junco’s evolutionary history. Part of Ordinary Extraordinary Junco (Chapter 3).
Less familiar to residents of the US and Canada are several junco groups that inhabit the highlands of Mexico and Central America. In this segment, researchers from around the world travel to remote high elevation habitats to study unique junco groups. They explore the concepts of endemism, geographic isolation, and the role of genetic data in classifying species. Part of Ordinary Extraordinary Junco (Chapter 4).
Explore how the nature of highly seasonal rainfall cycles and periodic fires create conditions that have shaped Mediterranean-climate ecosystems. Part of the "Mediterranean-Climate Ecosystems" series.
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).
