С.1, эп. 1: Koalas
19 ноября 2017 г.1 минTo most animals, eucalyptus leaves are toxic if you eat enough of them. Yet koalas eat almost nothing else. Their secret? Microbes. The tannins in eucalyptus keep the leaves from being digested, but the koala's gut is packed with bacteria that unlock the nutrients.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 2: Cats & Rats
22 октября 2017 г.1 минCats are cunning, stealthy hunters and for prey like rodents, the smell of a feline means stay away. But we see a rat heading straight toward danger. It's been tricked by a microbe.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 3: Coffee Borer Beetle
5 ноября 2017 г.1 минCaffeine is one of the world’s most popular psychoactive drugs. Caffeine is made in coffee plants--and can act as a deterrent to insect predators but one beetle has found a countermeasure--microbes.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 4: Puffer Fish
15 января 2018 г.1 минThese tropical fish have a signature defense. But inside some is more protection--a potent toxin made by microbes. Those with spines have even more security; and there’s a third defense that some of these fish share. A neurotoxin on the skin and inner organs that’s produced by bacteria. It can be deadly to many creatures including humans. Oddly, some blowfish with this toxin are a delicacy.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 5: Snowflake
3 декабря 2017 г.1 минMicrobes are the key to snow. When liquid water turns to ice, crystals sometimes need a place to start growing. Without that seed, water can cool to minus 40 degrees before freezing. Often, a bacterium acts as the seed. Bacteria are all around us, even swept up into the clouds by winds. There, they help ice crystals to form.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 6: Iguana
28 января 2018 г.1 минAfter they lay their eggs, iguana mothers don't stick around to help their young. Hatchlings must seek out the adults' droppings, loaded with microbes that will help them break down plants. Teamwork plays a part too. Highly social, the iguanas huddle in pods, spreading bacteria from one to another. Sharing germs gives these babies a boost at this fragile time of life.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 7: Hoopoe
11 февраля 2018 г.1 минThe Eurasian hoopoe have a difficult road to adulthood. But they have protection from bacteria; a gland on the mother secretes a bacteria laden-paste that the mother smears on her eggs. These microbes help to defend the egg and chick against disease. The foul smelling paste may even drive away predators. So this bacterial partnership protects the hoopoe against threats, both big and small.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 8: Weevil
18 марта 2018 г.1 минA grain weevil spends its early days nestled inside a cereal seed, but after it emerges into the world as an adult, the insect is in dire need of defenses. That credit goes to a microbial partner living inside the weevil’s gut, who produces the perfect chemicals to help build a sturdy, external skeleton.Бесплатный пробный доступ к каналу PBS DocumentariesС.1, эп. 9: Locusts
1 апреля 2018 г.1 минInside the gut of a locust is a powerful bacterial symbiont: a microbe that holds the key to coordinating the monstrous insect swarm. When the time is right, the microbe releases a chemical to help cue their insect host to take flight and head to greener pastures.Бесплатный пробный доступ к каналу PBS Documentaries
