Another post recommended by Juan Carlos. (If he keeps coming up with fodder for the blog I might just have to make him a co-author on the blog and have him write the posts too. ) Thanks for sharing the link!
This is a video from the California Academy of Sciences in which Jim Shevock discusses mosses. He covers their reproduction, water requirements and dessication tolerance. There are also a number of great shots of mosses in the field. It is a nice video I think to introduce folks to mosses and to simulate some excitement about them.
