John, The Cotton Grass entry was great. It really illustrated the idea of adaptations to a biome and along with the excellent series of pictures, it's a great teaching tool for environmental science. Please keep looking for these types of examples - they will be invaluable in the class room and I'm already seeing some opportunities to ask my students to start with the information you provided and then hypothesize how warming might affect the growth and success of that plant over time. The best part of this is that you are seeing examples that the textbooks will never have in them and making them available to all of us down south.
Take care and keep up the fine work!
Mike
