Superquark - S29E04: The Challenge of Courtship in Rivers and Lakes

The journey into the game of seduction continues with BBC documentaries in the fourth episode of "Superquark." The setting will be freshwater, which occupies only a small portion of the Earth's surface but is a vital habitat for millions of creatures that gather to find a mate. Success depends on perfect timing, which must be tied to the arrival of rains or the melting of ice. When you gaze at a river or a lake, you're often captivated by their beauty and the sense of peace they inspire, but this isn't the case for animals. They are among the most challenging arenas for courtship. We'll then explore a lesser-known aspect of transplants, one that nonetheless saves countless human lives. We'll discuss the Emilia-Romagna Region Skin Bank, connected to the Burns Center at the "M. Bufalini" Hospital in Cesena, one of five Italian skin tissue banks accredited by the National Transplant Center.
