Climbed a volcano on the weekend. I went from dry forest to rain forest to montane forest to shrubs to grasslands to bare moonscape alpine zones. The vegetation changed, the animals did, the weather did (oh boy, the storm near the top!). But I still found bromeliads at 1600m! And they had mosquito larvae in their tanks. Students, come and work on altitudinal gradients on volcanoes in Costa Rica! (but bring better rain gear, flimsy ponchos do not like strong winds ;-))
