The next programme deals with flying insects. It begins in Central Europe, where the Körös River plays host to millions of giant mayflies as they rise from their larval skins to mate. — the climax of their lives. Mayflies and dragonflies were among the first to take to the air about 320 million years ago, and fossils reveal that some were similar in size to a seagull. Damselflies are also looked at in detail.
On an island in the world's largest freshwater lake, a single, isolated population of moose battle for survival against a pack of wolves. Find out how this delicate ecosystem in the midst of Lake Superior reveals invaluable scientific information on the dynamics of predator-prey relationships.
Explore the stark landscape, frigid sea, and wild animals in one of the most remote and inhospitable places on Earth. National Geographic Pristine Seas Explorer-in-residence Enric Sala leads a group of scientists on the first international scientific expedition to Franz Josef Land. His team works with Russia's most formidable biologists, geomorphologists and ornithologists to understand how climate change is affecting this remote ecosystem. From diving in subzero temperatures to running away from polar bears to avoiding titanic icebergs, the Pristine Seas team faces some of its most dangerous challenges to date.

On a summer’s night, there’s nothing more magic than watching the soft glow of fireflies switching on and off. Few other life forms on land can light up the night, but in the dark depths of the oceans, it’s a different story: nearly 90% of all species shine from within. Whether it’s to scare off predators, fish for prey, or lure a mate, the language of light is everywhere in the ocean depths, and scientists are finally starting to decode it. NOVA and National Geographic take a dazzling dive to this hidden undersea world where most creatures flash, sparkle, shimmer, or simply glow. Join deep sea scientists who investigate these stunning displays and discover surprising ways to harness nature’s light—from tracking cancer cells to detecting pollution, lighting up cities, and even illuminating the inner workings of our brains.
