Lorena Gómez visits the Museum of La Salle University and takes a tour with Cristian, an expert on biodiversity. The tour highlights the fastest animals and insects in the world. Students learn about the fastest insect, the Australian tiger beetle, and the cheetah, the fastest animal on the planet.

Australia is home to great biodiversity from the rainforests on land to the Great Barrier Reef in the sea. It is the world's largest coral system and is located off the coast of Queensland, Australia. Part of the "Around the World" 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.
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.
Argentina is experiencing a decrease in native forests due to deforestation. As part of the process, only fifteen trees are replaced for every hundred cut down. This depletion of natural vegetation has devastating consequences for the environment. These consequences are immediate and long-term, if not reversed. Deforestation affects climate, biodiversity, conservation, and water absorption. Chapter 5 of Air: Climate Change Series.
Exciting discoveries can be found in the most unremarkable of places, and scientists were surprised by the diversity of lichen species growing on a rusty car door. They stumbled upon the door during a trip to Puerto Rico and brought it back to the museum to study the biodiversity. Part of "The Brain Scoop" series.
An important part of the conservation effort in Gorongosa National Park is to identify the species living in the park to ensure their protection and monitor their recovery. Every year, teams of scientists conduct biodiversity surveys in different areas of the park. Piotr Naskrecki leads a survey project in a particularly remote area, the limestone gorges of the Cheringoma Plateau, to study the bat population.
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.
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.
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.
Part of the "Branches on the Tree of Life" series. The term "algae" is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates, red algae (plastids with chlorophyll A), diatoms, yellow-brown algae and brown algae (chlorophylls A and C), and green algae (chlorophylls A and B). Explores the diversity, structure, ecological roles, and modern classification of these primary producers.
Great weather, abundant harvests, fabulous food, some of the world's most cosmopolitan and romantic cities are all attributes associated with Mediterranean climates. However, these regions are also critical biodiversity hotspots. This episode offers an overview of the world's Mediterranean-climate zones, pointing out their similarities, unique characteristics and importance, while also illuminating the factors that threaten them. Part of the "Mediterranean-Climate Ecosystems" series.
African penguins are critically endangered. Their colonies have been reduced by 70 percent in the last decade. Commercial fishing is a great factor in the penguins' population decline as the world's oceans are being overfished. With penguin chicks’ growth and health in crisis, a hands-on rescue strategy could sustain struggling colonies while conservationists work to ensure the species’ survival.
Can damage to coral reefs be repaired? Two researchers are looking for solutions to this question. Dr. Steve Palumbi conducts research on the corals around Ofu Island in American Samoa. He is trying to determine why these native corals can withstand ocean temperatures that, in other coral species, would lead to coral bleaching. Along with graduate student Megan Morikawa, Palumbi is testing whether these heat-resistant corals can be transplanted to reefs that have been damaged or destroyed.
Elizabeth Hadly has been studying biodiversity in Yellowstone National Park for 30 years. Accompanied by biologist Sean Carroll, she demonstrates different ways in which climate change is impacting the park’s ecosystems. Bark beetles are surviving the winter at higher elevations and killing a large number of white-bark pine trees, disrupting the food web that includes squirrels and grizzly bears. Climate change is also causing ponds to dry up, reducing the pond habitat and decimating the local amphibian population. Although the park provides protected environments for animals, it is not immune from global threats like climate change.
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?
