Скачать или смотреть Phragmites snorkeling: How does it survive water level fluctuations?

Guest speaker: Dr. Brian Sorrell of Aarhus University. This webinar focuses on the special adaptations that allow Phragmites survival in deep water, and how it responds to changes in water level. For Phragmites, staying alive means staying in contact with the air, with shoots acting as snorkels to transport oxygen down to the underground rhizomes. More frequent floods and fluctuations in water level are expected with climate change, so how will Phragmites cope with these changes? The speaker will explain the special, highly efficient gas transport in Phragmites stems and how recent discoveries about its gas transport are providing insight to its ability to survive different water regimes and water depths.
