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.

Ecosystems and biomes exist around the globe in various regions. Students will explore the plant and animal life found in tropical rainforests, deserts, and oceans. Part of the Real World Science series.
Different processes in nearby coastal oceans drive the ecosystems found in the Mediterranean climate zones. Atmospheric processes over the oceans influence seasonal rainfall patterns, while currents and ocean temperatures affect both local and regional climate conditions. Part of the "Mediterranean-Climate Ecosystems" series.
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.
Characteristics of the Mediterranean climate include great weather, abundant harvests, and some of the world’s most cosmopolitan cities. These climate zones also house diverse ecosystems, which are dependent of the geology of the regions. Part of the "Mediterranean-Climate Ecosystems" series.
Does anyone ever think about the four pounds of garbage they produce every day? Get down to the nitty-gritty and discover the delicate ecosystem of a landfill, including the potentially harmful byproduct methane gas. Viewers follow the stinky trail from curb to dump to uncover the fate of trash and the science behind decomposition. Part of the "Break It Down" series.
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.
The climate, animals, and plant life vary greatly in different parts of the world. Students explore how wildlife and the environment work together in harmony. They also learn how to identify and locate the seven major biomes found on Earth. Part of the "Way Cool Science" series.
The biosphere is a thin zone of land, air, and water that is home to all living things on earth. Discusses its features as well as characteristics of ecosystems and biomes, including biotic and abiotic components. Also covers types of terrestrial and aquatic biomes, and how ecosystems can change through a process called succession. Defines terminology, and concludes with a summary and quiz.
What is biodiversity? Students explore the concept of biodiversity as it applies to a wide range of ecosystems on Earth.
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.
Rising acidity in sea water is harmful to all ocean life. This short animated video explains how burning fossil fuels is increasing the acidity of the world's oceans. This is also impacting the fragile underwater ecosystems.
The American South is home to some of the world’s most spectacular ecosystems, from coral reefs to salt water marshes. These two national monuments are underwater paradises and support a diverse and complex system of plant and animal life.
The intertidal ecosystems lining Florida’s Gulf coast are economically important, but in decline. Dr. Randall Hughes and Dr. David Kimbro, two Florida State University marine ecologists, hope that by studying them, they might gain knowledge that will help preserve salt marshes, oyster reefs, and seagrass beds. Part of the series "In The Grass, On The Reef."
Living and nonliving things make up the world. Students will learn how living things interact with each other and with nonliving things in an ecosystem.
Ecological succession is the gradual process by which ecosystems change and develop over time. In this episode, Pinky and Petunia discuss how nothing remains the same and habitats are constantly changing. Part of "The Amoeba Sisters" series.
Presents an overview of a typical ecosystem, introducing and explaining terminology, while stressing the interdependence of its living and nonliving components. Explores basic principles of ecology, and mentions various ecosystems and their general characteristics. Short quiz follows the summary.
Explore the vastly different ecosystems of the rainforest and the jungle. This video discusses the diversity of their vegetation, animals, and insects. From the Kool Books series narrated by Hector Bonilla.
Ana Luz Porzecanski is a conservation biologist. She studies wildlife and ecosystems. In this interview, she discusses how humans and nature can coexist and thrive together. Part of the "Meet the Ologist" series.
Symone Johnson, educator at National Aquarium, provides an overview of the series "Coral Comeback." She outlines coral reefs and discusses their importance to healthy ocean ecosystems. Part of the "Coral Comeback" series.
