My guest today is Dr. Rafa Medina from Augustana College in Rock Island Illinois and he comes to us with a wonderful citizen science opportunity. Dr. Medina is interested in moss evolution and how polyploidy may factor into the equation. To better understand this process, Dr. Medina and his colleagues are hoping that you can provide samples from all over North America and Europe of a common moss affectionately referred to as goblet or bladder moss (Physcomitrium pyriforme). Join in and learn how you can be a part of this incredible research.
